Got the retractable hose what modifications do I need to do to it?

Take the spring out and get rid of the hose. Should take 100 feet of quarter in hose. You will also need a short length to go from the side of the hose reel to the machine.

[Simon Gerrard]

Be careful taking the spring out btw.

[Adrian Walton]

HI Simon thanks for that any ideas were the oriface would be? The machine is definitely not  dumping water as i've had the pipe off the thermal valve and not a drop when machine is up to temprature and water box is stone cold.

[Simon Gerrard]

I don't have one but have just looked at a picture of one and it appears to be between and slightly below the two solution quick connects. Usually a brass nut and then you will need an allen key to get the jet out which is inset about a quarter of an inch in the housing. They are usually a stainless steel fitting with a small hole in it, you will probably find that it is blocked, so clear it and you shouldn't have a problem. A good way of checking it is working is to undo the brass nut and a fine jet of water should start appearing, if not it will need cleaning. You should check this regularly.
That jet keeps the water moving around the system from the heat exchanger to the water box. If you leave the machine standing for too long the water box will get too hot and the thermovalve will open allowing cold water into the water box hence preventing an overheat shutdown.

An orifice jet looks like this:

[Adrian Walton]

Not sure i've ever seen one of those on my machine i think chris at alltec said there wasn't one on it.On the front there is a stainless steel nut which is a check valve for the chemical pump and the other is a brass nut with a big filter behind it which has never had a bit of scale in it any time i,ve taken it out in the eight years i,ve owned it.

[Simon Gerrard]

Hmm, that's odd. Best ask a Thermalwave guy.

Centre of the bottom panel, two brass nuts, one will house the orifice. Section 5 of the manual

I have the Bluewave not the Thermalwave although the manifold looks simlar,on page 67 part no 10 is the filter i was refering to and shows nothing else behind it and part no 9 is a check valve for the chemical pump.
think i,m going to have to take a few bits off and see if i can find something that's blocked.

[Adrian Walton]

Just seen the bits your talking about on page 68, not sure mine has this.

[Simon Gerrard]

Adrian,
I've asked the question on truckmounters, someone on there will have one.

Simon

[Adrian Walton]

Thanks simon i think mine is the only one in the uk as alltec only ever brought the one over but i think the plumbing on the petrol versions is the same.

I luckily live in a very soft water area. The importance of descaling cannot be over stressed  but using acid rinse
Buy the proper stuff.

Sorry to hijack this thread but i have a similar problem with my Bluewave Diesel, plenty of heat but waterbox is staying cold and machine overheats if left idle for any length of time or using a hand tool on full revs.
If you look into the waterbox you can see a tiny stream of hot bubbles coming back in but not enough to get it hot to open the thermal valve, Ive descaled it but no improvment.
thanks Adrian

Ive got the Thermal Wave. On the Bluewave is the engine water cooled?

[Adrian Walton]

Hi Dave, yes it's a water cooled kubota diesel.

[Dave_Lee]

The only times I have had cutting out and re-starting problems with my Thermal Wave was when the engine coolant level in the radiator was slightly low and another occasion when the Waste tank high water level switch stuck in the up position.
Dave.

[Adrian Walton]

Dave the only reason its cutting out is because the engine is overheating due to water not circulating around the whole system and it not being able to dump the excess hot water ,it sounds like it has a blocked oriface but it dosn't appear to have one so something else must be blocked or scaled up.

[Simon Gerrard]

Adrian,
Every TM has a recirculating jet, otherwise we would all be plagued by your problem. Have you checked your water pump belt isn't loose and that the radiator is full?

None of mine have them.
