Operational instructions of caravan combi heater
Start-up heater
Use special liquid crystal switch to operate.
Fuel oil, electricity, mixing mode, heating water tank or unheated water tank for main engine heating are set according to need.
-- Check the power supply capacity of RV camps, and choose the operation mode of 900W (3.9A/7.8A) or 1800W (7.8A/15.6A) accordingly.
-- Check whether the smoke exhaust cap is unobstructed.
-- Open Liquefied Gas Tank Switch Valve
-- The tank is full of water when needed
Filling of water
Check whether the relief valve/drain valve is closed.
--Turn on the pump power supply (main gate or pump switch)
--Open the hot water tap in the kitchen or bathroom and keep the valve open until the air in the container is discharged and the water is continuously discharged.
--In the absence of water heater heating, if only the cold water system is in operation, the water heater will also be full of water. To avoid frost damage, the water heater must be drained through a safety/drainage valve, even if it is not running.
--In the case of frost, the frozen residual water can prevent filling. The water heater can thaw (no more than 2 minutes) if it is turned on for a while. The ice can be thawed through the inside of the heater.
--If the heater is connected to the central water supply system (rural or urban water supply system), a pressure reducer must be used to prevent pressure exceeding 2.8 bar (0.28 MPa).
-- Open the circulating pump
-- Open the hot tap in the kitchen and bathroom until the air is exhausted and the water tank is filled, and the water is not interrupted.
