21 - AIR CONDITIONING CONTROLS (OPTION AIR CONDITIONING)
The air conditioning only comes on when the forklift truck has been started up. When using your air
conditioning, you must work with the doors and windows closed.
In winter: So as to ensure correct operation and complete efficiency of the air conditioning unit, start up
the compressor once a week, if only for a short spell, so as to lubricate the internal seals.
In cold weather: Warm the I.C. engine before switching on the compressor, so as to allow the coolant
that has collected in the liquid state at the lowest point of the compressor circuit to turn into gas under the
effect of the heat given off by the I.C. engine, as the compressor is liable to be damaged by coolant in the liquid state.
If your air conditioning does not seem to be working properly, have it examined by your dealer (see: 3 - MAINTENANCE: F - EVERY 2000 HOURS OF SERVICE). Never
try to repair any possible problems by yourself.
DESCRIPTION OF THE AIR CONDITIONING CONTROLS
A - Air conditioning system ON/OFF control switch with indicator lamp. Only works when control switch "C" set to 1, 2 or 3.
B - Air temperature control.
C - Air flow and fan speed control. When this control is set to "0" the air conditioning system will not work.
NOTE: Possible losses of water under the lift truck are due to condensate discharges caused by the drying effect of the installation,
especially with high outside temperatures and high relative humidity.
For the air conditioning to perform properly, the air intakes must not be blocked by frost, snow or leaves.
When the facility is running, at least one of the cab air grilles must be open so as to avoid any risk of freezing to the evaporator.
