Easy Installation Guide.

(UNIT ONLY - Kit NOT included with this product, kits can be purchased in our Ebay Store)

Mount your heat exchanger using the bracket provided.

Your heat exchanger has 4 connections. The coloured collars on the connections identify the relevant hot/cold connections.

2 large ones are for connection to your vehicle coolant system.
2 small ones are for for your fresh/shower water.

Although your Heat Exchanger will work when mounted in any position it is most efficient when mounted upright or on its side with the hot fresh water out and the engine coolant in hoses (both red collars) uppermost. 

Heat Exchangers are designed to be fitted in parallel with your vehicle heater system. Cut both heater hoses and tee off to your heat exchanger from both hoses. Best results are obtained by operating your shower with the vehicle heater turned off as this directs the flow of water over the heating coils and increases the heating efficiency.

Mount the bumper bracket on your bumper or other easily accessible location. 
Connect the 2 barbs on the bracket to the inlet and outlet on your heat exchanger.

If mounting your Heat Exchanger high up in the engine bay, it may be necessary to rotate the exchanger so the "engine out" connection is vertical. Start and run the engine for a short time. This will eliminate any air lock that may have formed.

Note: If you have a shower enclosure or wish to wash away from your vehicle, you can gravity feed fresh water from a drum or bucket on the bonnet through the heat exchanger into another container.

First burst of water will be very hot as this was trapped in the heat exchanger, water temp will drop to around 50-60 deg C and then be delivered continuously for showers etc.

Do not install the Heat Exchanger or hot water outlets inside the passenger compartment! All components should be under bonnet/ under car or on bumper bar.
