Jukebox and Classic Cars

As you arrive into Hamilton off the expressway from the north, you will see at one of the roundabouts, a car on top of a pole.

We went through here with Gary and Dianne before they headed back to Taupo and were sitting in the carpark getting ready for a cuppa while waiting for Fiona. She was really taken with the Messerschmitt.

Mike’s Fridge upgrade – The Detail

Mike and Wendy are the proud owners of a French Rapido A class Motorhome which they bought nearly a year ago.

He discovered after he received it that his fridge wasn’t doing what he wanted it to and being the clever person that he is, and a Plumber and Gasfitter with more than 40 years experience,  he decided to do something about it.

Some of you will remember his earlier post but this greatly expands on what he did earlier.

In Mike’s words and pictures .. Go Mike:

RAPIDO OTT RV FRIDGE UPGRADE

French Import: Rapido
Model: 890F
Year of manufacture: 2014
Length: 7.39m
Width: 2.35m
Height: 2.82m
Fridge make: Dometic
Fridge model: RMD 8505
Fridge climate classification: SN
Type of Gas: LPG

rap2My name is Michael Brick. We were luckily enough to purchase a Rapido A class motorhome which we really love.

Over the past year there have been a few upgrades mainly to accommodate our needs. Firstly I installed a new LPG regulator which was part of certification requirements and a pipe system upgrade to accommodate the two gas bayonets at the rear of the motorhome, then the outside shower and finally the OTT FRIDGE UPGRADE.

The original fridge installation carried out by Rapido was to good manufactures specifications, however the fridge’s cooling ability was not meeting my specifications.

At this stage I would like to point out I am not a fridge technician, however I have 45 years experience as a Certifying Plumber and Gasfitter.

THE OTT FRIDGE:

Unfortunately the data plate revealed an: “SN climate classification” SN = Subnormal, suitable for use in ambient temperatures of +10°C to +32°C suited for European countries.

Ouch!!! I was told, better to have had the ST climate classification.
ST = Subtropical, suitable for use in ambient temperatures of +16°C to +38°C suitable for NZ climatic conditions.

To find a solution I wrote to Dometic NZ with the following questions and was pretty chuffed to get a very comprehensive reply.

Q. What are the differences between the “SN” and the “ST” climate classification fridges.

A. “T” rated fridges have something called VIP vacuum insulation panels, high value insulation, better insulation in the door et.

If you purchased a “T rated” fridge and put it in the existing cavity it would not go any better. The main issue is the venting. If you take the top vent out and can see the condenser fins it will not work. The bottom of the top vent should be above the top of the fins and a deflector plate from the top/back of the fridge to the inside/top of the vent. While this may seem a subtle difference it makes all the difference.

MY INSTALLATION.

THE COOLING TOWER

Proper baffling of the upper portion of the cabinet is a must to prevent eddies of air from hindering the hot air from escaping.

A lack of airflow across the condenser fins may require additional fans to help circulate and exhaust the hot air from the cooling compartment.

1www1). FAN BRACKET:

Through the LS300 vent aperture I lowered a 25x25mm aluminum angled bracket to 40mm below the condenser fins, then fixed to the side walls. The fan was then lowered and fitted to the alloy bracket (long screw driver needed).

2www2). THE BAFFLE: This pre made baffle was lowered through the LS300 vent aperture. The long flat portion slides between the alloy bracket and the outside wall of the motorhome. The top of the baffle is set 6mm below the bottom of the condenser fins.

3www3). THE FLUE: Spills temperatures of over 200 degrees into the cooling tower next to the cooling fins of the condenser. To stop this heat spilling around the fins I created a division in the baffle then fitted a curved shield around the chimney/flue pipe to guide hot gases up towards the vent aperture.

4wwwThis photo shows the position of the baffle. The top edge is  placed 10mm below the cooling fins. The cold air travelling up the tower is diverted onto the cooling fins.

5wwwThis photo shows how the bottom of the baffle interlocks with the fan bracket. The baffle can be raised or lowered to, to set the correct distance from the condenser fins.

4). BOTTOM FAN:  this is placed at the bottom of the cooling tower. Controlled by a 70 degree temperature thermostat (normally open) and a switch wired into the fans power supply so that I have control over when the fan is on.
Duratech 120mm: YX-2584
Air flow: 64.3 (CFM)
Current: 0.22A
Fan Speed: 1500 rpm
Noise: 25dBA
Burner Pressure: 2.75kPa

6www5). TOP FAN: This is placed under the cooling fins of the condenser. Controlled by a 50degree temperature thermostat (normally open) and a switch wired into the fans power supply so that I have control over when the fan is on.
Duratech 120mm: YX-2584
Air flow: 64.3 (CFM)
Current: 0.22A
Fan Speed: 1500 rpm
Noise: 25dBA

7www6). FRIDGE FAN: This is a  double fan assembly fixed to the cooling fins by an alligator clip.

These fans are controlled by a 100 degree temperature thermostat (normally shut) and a switch wired into the fans power supply so that I have control over when the fan is on. Wires for the fans run through the hole provided for the thermistor cable. To gain access to this hole, the cooling fins have to be removed.
Air flow: 14.7 (CFM)
Current: 0.18

7). FRIDGE FAN: This is a single fan fixed to the bottom of the 2nd shelf right hand side of the fridge. Testing in many spots found this to be the best position.
Controlled by a 100 degree temperature thermostat (normally shut) and a switch wired into the fans power supply so that I have control over when the fan is on.
Duratech 90mm: YX-2572

Fan Speed: 1500 rpm
Noise level: 20dBA

8www8). TEMPERATURE THERMOSTATS:

9www9). FAN SWITCHES: there is full control of all fans.

10www10). THERMOMETERS: Two type K thermometers are visible for convenient monitoring of temperatures.

The top thermometer: Its wire probe is placed under the 100 degree thermostat. When temperatures of 100 degrees are reached, the fridge fans have turned off. In essence the fans just tricks the fridge into cooling for longer periods.

If the fans were installed with no means of control the cooling cycle remains on too long, which under certain circumstances may cause overheating of the ammonia.

The bottom thermometer: This records temperatures of the rich ammonia solution eg the cooling process. It’s wire probe is attached to the liquid heat exchanger which is below the absorber tank.

The digital Manometer:
This shows the fridges correct burner pressure of 2.75kPa.
Note: If you increase this pressure you can expect your flame to produce more heat and higher temperatures throughout your cooling system.

11www11). TESTING: While comparing the fridges performance on LPG I noticed the ammonia temperatures were a lot higher than when testing on 230 volts. With concerns there maybe a overheating issue I wrote to Dometic NZ. Again, I was very pleased with there informative response.

A. Dometic AU.

While running on an element such as 12 volt DC or 240 volt AC the heat input is over a very precise area around about 85 mm in height this is shorter than the actual element as the filament in the body of the element is short than the over all of the element.

The electric elements are held against the pump tube using steel tubes welded to the side of the pump which directly conducts the heat energy into the side of the pump tube.

The gas flue is welded to the pump tube in the same area as the electric elements for about 90 mm so you end up with the 2 electric sleeves and the gas flue tube all welded to the pump for the same distance and in the same vertical location.

The difference is the electric elements only produce heat energy over a short distance you could say the full length of the welded sleeve about 90 mm, yet the gas flame running up the gas flue heats the full length of the gas flue. The part of the gas flue welded to the pump does all the work adding heat energy into the pump in the right place to separate ammonia from water.

The fact the gas flue runs up the pump tube means there is added heat energy leaking into the overall vertical height of the pump tube which does not happen when running on electricity.

The gas flue is located so it does not touch the pump tube above the weld but it is still very close and encased in insulation which holds in the extra energy.

The result is while running on gas you have a number of things happening which do not happen while running on electricity.

The steel pump tube on gas is hotter all the way to the top and conducts more heat all the way across the condenser.

There are also chemical reactions taking place inside the tube which raise the condenser surface temperatures due to the prolonged heat input over the full length of the pump.

With the added heat to the pump above the weld the pump tends to add more steam to the mix leaving the pump area so the ratio of ammonia vapour and water changes when compared to electric operation.

With more steam (Water) in the mix the condenser must work harder shedding more heat as it turns the steam into water which runs back to the pump.

Stating the above is true however added heat to the condenser without increasing the airflow to remove that heat will raise the surface temperature. This all designed into the unit and is expected.

Just because the temperature goes up in some areas when running on gas doesn’t mean the overall result is not the same as when on electric.

Higher surface temperatures through the condenser while running on gas is not unusual.

The top thermometer is 1 degree out. The correct reading is fridge -1, freezer -19.

The Markets

After the Covi Show, I picked up Fiona  and we decided to head up north. Waipu sounded good and we with the weather looking good for the weekend, we knew we could probably stay at the Caledonian Park.

The trip was easy and we scooted up the motorway and up  to Waipu arriving early in the afternoon. We were greeted with a No Camping sign which looked a bit flash but looked as though it might have been forgotten about and left out by accident.

It is such a nice place to stay that I thought it was worth a phone call  to see what was up. The really nice chap on the other end said that it was because they had two weddings over the next two Saturdays and they didn’t want big motorhomes being in their faces just outside the window  BUT ! .. if we were to park down the other end and and park end on, we were welcome to stay the night.. yippee !

Parked end on at the end of the field. Alan and Bev on the right. The wedding in the hall in the distance

$10 a night with power, just behind the main street in Waipu, fabulous spot and walking distance to everywhere.

Just after we got settled, a knock on the door from another motohomer asking about the sign. I gave him the number, explained about the weddings and he parked more into the trees than I was. Fiona wanted her TV signal so that prevented me from getting right underneath  🙂

Alan and Bev were English and had been here for most of summer and are retired camp ground owners and have been coming here to see their family. Nice couple and they’re currently trying to sell their motorhome to go back to the UK.

We decided we’d walk down to the McLeod Pizza barn where the pizzas are fantastic. Thin bases with heaps on them and very good value.  I had been suffering from hayfever so was feeling pretty knackered so after that, we headed back to Rafe and crashed.

Under the trees in the sun
Under the trees in the sun the next day

The next morning, the sun was out and it was market day. Every Sunday, they have a market at the hall in the main street. Great vibes with local people doing their thing.

As the day went on, Bev and Alan left to go down the coast and several new people came in with their vans. It really is a great spot in fine weather. The grass is solid but I’m not sure I’d want to be there after or during a heavy all day rain. Their is some gravel parking with power around the other side for that but being under the trees in the sun was very pleasant.

Later in the day, our water pump started making some funny noises like louder and a bit whiney. I texted Jonas the importer and he suggested we get it looked at as we passed the repairers at Silverdale. On the way home the following day, we stopped of at Vantage RV to get it checked out. Johan turned the galley tap on and looked at me with a “yuk” type face. “We won’t waste any time with this” as he left and went and got another pump and installed it there and then. The submersible pump showed signs of being on its last legs, with water creeping up the wire into the pump motor and Johan reckoned it was not far off seizing. It must have been a duff one from the start. The whole process took less than an hour and we were off back to Milford.

Hats off to Jonas (Dethleffs NZ) and Johan and the team at Vantage RV for very prompt service.
The whines from the pump were bad, imagine the whine from Fiona if she had no water 🙂

Karangahake History

On the way back from Waihi we stopped in for a look at the Karangahake gorge.

The two Batteries over the bridges. Karangahake at its best!

We are intending to do the bike trail but it’s all about gathering up more knowledge before we take this on.

It’s a really interesting area with several short walks that are not part of the trail. We had a look at a couple of the old power stations and batteries while we were there which takes an hour according to the sign. The walking doesn’t take anything like that and it’s well worth a look. 

Click on the images to see them in hi res or slideshow

Karangahake was a small town which included all the things you’d expect to see in a town like Te Aroha or similar. 

We walked across the swing bridges and up the hill past the power station, the two batteries built down the hillsides. The ore was swung across the river from the tops of hills in a flying fox type of setup before processing with cyanide. It really was a huge setup. It’s not until you’re up there that you realise the scale of it all and looking at the remains, what it must have taken to build the buildings themselves and the infrastructure to go with it.

We walked all around and as the weather deteriorated, we worked our way closer to Rafe in the carpark. Another one of those feature areas that I’ve driven past lots of times and was really pleased we stopped for a look.

The Goldfields train

Isn’t just great having the NZMCA app now running on our iPads. Even though I’ve had the gps files installed in Rafes in dash gps, it’s really nice sitting in the deck chair with the iPad and figuring out where to next with the app.

We found in the iPad, a great spot in Waihi that sounded fantastic. It’s at the Goldfields railway station at Waihi. For $10 per night, there are 6 powered sites and more space for others as well. There is also access to water and the Rail Trail toilets as the Rail Trail ends at the railway station. About 15 minutes walk away is the centre of town.

We arrived and plugged in, paid for the park and we’re just in time for the last train ride to Waikino and back. The perfect way to check out the bike trails before walking or biking the Karangahape gorge trails.

The train stops for 15 minutes or so, just enough time for a beer, glass of wine or just a coffee or ice cream. A great way to spend a couple of hours and fun too.
There are 3 return trips each day from Waihi.

Gulf Harbour

Over the last few months there has been quite a lot of discussion on the NZMCA forum on the changes to the Free camping area at Gulf Harbour.

Nice spot for overnighting with a great view

We were going to spend a night with my brother in law John and his other half Marnie at Silverdale and as we were a bit early, we decided to check it out and stop for a cup of tea. The weather wasn’t playing the game so it wasn’t looking its best as the nice overnighting spot that it is.

Nice for a cup of tea, Great outlook right back to the City

I think the council have done quite a good job of separating the boat trailer car parking, the Motorhome parking and the ferry parkers.

The sign writing is nice and clear and allows plenty of room for everyone.

My only comment for improvements would be to take a leaf out of Taupo councils book and paint the 3m fire safety gap, as No Parking between each park, so the tourists and those not aware,  don’t try to jam in late at night.

Oops, maybe here for the day
Oops, maybe just stopping  for a moment.. Nice long trailer parking for the boaties.

We only stopped for a look and moved on to Silverdale but a big improvement.

Wairakei Steam

I don’t know how many times I’ve driven past Wairakei over the years but as we left Gary and Diannes place this time and we had  plenty of time, I thought we’d get a closer look at where some of our power comes from.

The plumbing undera bridge and the steam

After taking a couple of wrong turns and ending up at a  semi rural café and camping ground down a dusty road and getting rafe all covered in muck and another turn ending up at a Contact office block, we found the Lookout road alongside a BP service station. There is very little to say where the lookout is but the road leads along fences, past lots of expensive looking plumbing and you end up driving up a hill to the lookout. Well worth the effort.

Amazing to think that all that heat comes out from under our feet and creates our power or at least some of it.

Tug Racing lots of images

Anniversary Day on the Waitemata Harbour (Auckland Harbour for our off shore friends) is always a spectacle. Especially for those of us that like to smell some diesel and hear some noise  🙂

Oh and by the way –  this is still a motorhoming blog 🙂 .. apologies for all the marine things but its that time of the year !

Wenderholm – another great Auckland Park

With the heatwave, if you can call it that, we set off for a park beside a beach where we could swim.

Our friends Rob and Helen have stayed regularly and highly recommended Wenderholm Self Contained parks. The park is well setup with a boat ramp (tidal), Electric BBQ’s and Picnic Tables that are free to use and nice new toilets too.

Remember to click on the images for Hi Res

I was surprised it was so busy for a Monday but it was hot and it is still holiday time. As the day went on, more motorhomes arrived and while we had a glass of wine before tea, a visitor from Wellington was out entertaining us with his metal detector looking for treasure.
He found a house key, several coins and said he’d previously found an expensive ring!

I’m think that I would prefer to park in a fenced off parking area like Sullivans Bay, another Auckland City Park further north.  In saying that, where we were and because there were a few of us, it gave the impression that it was a motorhome area and cars didn’t park near us.

The Beach at Dusk

We have had a  situation  where we’ve been at beachs where the day trippers have been quietly drinking all day and leave to drive home where they can barely walk.(Not this one)

All in all, a nice place to stay, nice beach and things to cook on too.

Left right, left right, attention !

What a great weekend! The weather was great and we had things to do.

After Fiona had finished work, we headed out to one of our favorite spots, the NZMCA park at Ardmore, a hop skip and a jump from Alex, Sarah and the Grandkids.

As always, remember to click on the images to see Hi Res.

Rob & Helens Autotrail and Rafe
Rob & Helens Autotrail and Rafe

Our friends, Rob & Helen and their daughter Chloe were heading off for a week or so to Napier and Gisborne so it was great we could pop in to Ardmore to see them off. When we arrived at about 7:30pm, they were off on a walk so they were a bit surprised to see us there when they returned as we hadn’t confirmed that we would be there.

Alex, Sarah and the boys came over after their tea and we all caught up in Rafe. Lots of fun.

The Ardmore NZMCA park is in an airfield precinct so a little noise comes with the territory, usually small planes and sometimes Helicopters.

That morning, things were different. At 8am, we heard the repetitive bark of a Sergeant Major type next door in the cadet parade ground teaching St John Juniors how to march. It was quite interesting to watch too as some didn’t know the left from the right so there were some interesting moves happening.
They were all togged up in their black uniforms and looked good, some even wearing their medals. There was one trainer who forgot his black clobber and was doing it all in his Red shorts.

As Fiona said, good on him for volunteering his time on a Saturday morning but it did sort of spoil the overall look.

About 9:30, we said goodbye to Rob, Helen and Chloe and they headed off to Taupo for their trip to Hawkes Bay and beyond. We left as well and went around to Alex, Sarahs and the Grandkids for the morning and around lunchtime, headed towards one of our other favorite places, Rays Rest at Miranda.  We were  catching up our friends Gary and Chris who were helping other friends Mark and Tina with their first trip out in their new, second hand Motorhome.
Rays Rest is a great spot and the weather was behaving as well.

Rays Rest

After arriving early in the afternoon, we caught up for cups of tea and later a couple of drinks and then  headed off in Gary’s van down to get the fish and chips for tea from the famous Kaiaua fish and chips shop.  Gary wasn’t drinking so that worked well.  It was nice to see how much progress Mark had made on his motorhome as when he got it, it leaked and had quite a lot of dampness in its linings. .. now all gone.  More on this in another post soon.

We had a great night together and called it quits and hit the hay.

The next morning was nice in diffused sunshine with little wind. We sat on the foreshore watching people fish and just soaked up the atmosphere.

Gary, Chris, Tina and Mark were going to carry on to Thames and Coromandel so after lunch, we left them and headed home. A nice weekend.
