Temperature and adjustmentThe thermostat cannot be adjusted and ispre-set to approximately 70°C.Water heaters (as with all other gasappliances) should be switched off and thegas cylinders turned off when the caravan isin motion.TO OPERATE THE HEATER ON MAINSELECTRICITYEnsure that the caravan is connected to thesite mains and the supply is adequate. (Theimmersion heater uses approximately 3.75amps.)1. Switch on the isolation switch. If it is theilluminated type, the light should indicatethat the heater is working.2. To switch OFF, switch off the isolationswitch.Over TemperatureImportant: If the mains electrical supply tothe heater is switched on but the heater isnot working, the over temperature thermostatmay have operated.This can be due to:1) Switching the heater on without water inthe tank. Always check that the heater isfull of water before switching on.2) Failure of the normal operatingthermostat. Manually reset the overtemperature thermostat by pressing thebutton in the centre of the electricalFASTDRAINDRAINPLUGconnection box. If the operatingthermostat has failed the overtemperature thermostat will again trip out.If this occurs DO NOT USE THEIMMERSION HEATER and consult yourCarver Dealer.FROST PRECAUTIONSIMPORTANT:During periods when the heater is likely tofreeze (e.g. when the caravan is stored duringthe winter) it MUST be drained down toprevent damage.Fitted EquipmentTo fast drain the system:1. Park the caravan on level ground.2. Ensure that the gas and electricity areturned off.3. Open all hot and cold taps and showerheads if fitted.4. Remove drain plug and store in safe placein caravan (e.g. kitchen sink).5. Using a flat bladed screwdriver, turn thefast drain 90°.The water system will now drain - this islikely to take 5 minutes.Remember that at least 9 litres (2 gallons) ofwater should drain from the system.At the start of the season insert the drainplug and sterilise the system by using asterilising fluid, e.g. Chempro SDP or similar.DO NOT USE DOMESTIC BLEACH,CAMDEN TABLETS OR SODIUMMETASULPHIDE.If a filter is fitted it is recommended toreplace it at the start of the season.TO RECOMMISSION THE HEATERClose cold taps and drain plug andreconnect the pump. Let the system fill withwater until water flows steadily from the hottaps. About two gallons of water will berequired. Once the hot taps are flowing freelyclose them and switch on the Cascade 2 GEheater.49
