The heater has an integrated resistor pack offering 3 speed control; OFF 1 2 & 3. No switch is supplied with the kit, please view our range of multi position switches in our store.
Please ensure your supply is fused appropriately, it is recommended to use a 12 to 15a fuse and that your cable is rated higher than the fuse.
Please note that a corrosion inhibitor such as glycol or anti-freeze should be used to prevent corrosion and prolong the useful life of all components used in the vehicles cooling system.
The water valve is not a bypass design, when in the OFF position no water will flow back to the engine, therefore this heater is unsuitable for use on a vehicle which also uses the heater circuit as the engines thermostat bypass circuit. If your engine has no seperate thermostat bypass circuit then please look at our other version of this heater without water valve and also our bypass type water valves.
Please make sure that no foreign matter can be ingested into the fan, this is the quickest way to destroy blower motors and could potentially cause a fire. For example, this is particular important if the heater unit is installed onto or close to the floor of the vehicle. If you intend to mount this outside of the interior compartment then it would be recommended to install a filtered cover to protect the blower and ensure long operation life.
