A/C and Heater

Wet type heater

When error codes F01 / F02 / F07 are read on the cab heater digital indicator, fill the fuel level and turn the cab heater switch off and on. Repeat this procedure until the air inside the cab heater fuel system is completely eliminated, and cab heater operates normally. (Do not turn the heater switch off and on before filling the fuel tank) When any error code is repeated less than 3 times, cab heater continues to operate normally. However, when (an) error code(s) are repeated more than 3 times successively, cab heater switches to protection mode and indicates an F12 error. In this case, circuit breaker shall be turned off and on again, and thus cab heater shall be reset after refilling the fuel tank. When the reset procedure is completed, cab heater switch shall be turned off and on. Error F12 may be indicated 1 or 2 times as per the air amount in the cab heater fuel line. In this case, resetting procedure shall be repeated.

CAUTION Pump is delicate. High quality diesel fuel shall be used against freezing. Fuel consumption: 0.7 l/h during the initial start-up when the temperature inside the cab is low; and 0.4 l/h for the operating phase. Blowing temperature from the nozzle is 75°C. Thermostat operates between +5°C and -28°C. Do not cover the blower and the intake nozzle inside the cab. This is important as it affects the service life and the speed of the motor. CAUTION In-cab auxiliary heater hot air outlet is behind the driver’s seat. Therefore, dangerous material such as flammable or explosive material shall not be placed between the driver’s seat and bed.
