HEATING SYSTEM
General description
The heater is switched on and adjusted by rotating the control knob at the roof console, then switching
on the blower and setting the selector at the preferred speed .
To warn the cab up quickly, the knob should be rotated fully clockwise and the blower set to speed 3.
The screen is demisted or defrosted by air directed through a slot vent . For defrost or fast demist, all
other vents should be closed off.
IMPORTANT:
Ventilation is provided by a single blower unit serving both the heating system and the air conditioning
system.
After reaching the desired temperature adjust the system to suit your needs.
NOTE:
-For ideal system operation, the engine must run at 1000 rpm
Warning
Before starting the engine, make sure the system is off
(by turning off the ventilation fan) so as not to overload the battery.
After the system at full power for a long period of time, never turn it off suddenly but
let it first idle for about 20 seconds.
