It is absolutely necessary to bleed the air out of the UTV’s
engine cooling system. Incomplete bleeding of cooling system
can result in engine damage. If you don’t have sufficient
experience with this process, we strongly recommend
professional service technician assistance. We are not
responsible for damages when cooling system bleeded
incompletely. Please note that aditionall heater system will
absorbed more than 2 liters of coolant fluid.
1. Important: After the heater system installed check the system for leaks.
Turn on the electric vent switch and confirm that the engine is cold.
Start the engine, open bleeding valve and wait untill engine warmes up.
Important: Allways check engine temperature – if it overheats turn of engine.
2. To achieve engine operating temperature depress the accelerator to increase
The engine RPM. This will increase the preasure and flow of the water pump
forcing more coolant through the heater. After operating temperature ceache turn
of engine and open it. Trapped air should come out from heater system
throughout bleeding valve. Repeat this procedure until heater/cooling system is
completely bleeded out.
The DFK Cab heater, like the heater in a car, generates heat from the vehicle’s
engine.
In nearly all cases, the heater should generate enough heat from your UTV, side
by side, or tractor engine that you may need to turn the heater off periodically
otherwise the air in the cabin may be too hot.
It is important to check the coolant level regularly at least 4-5 times during the first
several days of operation and fill as necessary until the coolant level has stabilized.
The heater will draw and retain coolant, sometimes at the expense of coolant to
the engine. This can cause engine overheating if not managed properly.
