ROPS CAB, AIR CONDITIONING AND HEATING INSTALLATION - OPERATION Continued
AIR CONDITIONING ONLY Continued:
(Normal operation)
1. Switch the blower switch to achieve the desired airow.
2. Turn the temperature regulator clockwise to set the desired
cooling temperature. When the set temperature in the cab is
reached the thermostat will switch off the compressor and
the blower will continue to run.
When the temperature rises above the set temperature, the
compressor will automatically restart.
3. If cab heating is required, switch off the air conditioning and
turn the hot water valve anti clockwise to increase heating
to the desire amount. The blower speed is controlled by the
rotary switch as with the air conditioning.
4. If the mower has been left in strong sunlight and the interior
has a high temperature, set the blower speed to maximum to
provide fast cooling.
ROPS CAB, AIR CONDITIONING AND HEATING INSTALLATION - MAINTENANCE
1. All work on the refrigerant part of the air conditioning
system should be carried out by fully qualied personnel.
2. The air conditioning system can be used for many months
of the cutting season. The regular prescribed maintenance
must be carried out to prolong the life of the system and
ensure efcient operation. Failure to carry out the prescribed
and documented maintenance could invalidate the warranty
on the system and its components.
3. Do not spill compressor oil on the vehicle surface. It can
cause discolouration of vehicle paint and deterioration of
acrylic or ABS plastic components.
4. After the rst four weeks of use check all connections for
tightness.
5. Even if the air conditioning system is used infrequently,
the maintenance schedule must be followed as ageing and
refrigerant loss can occur with time. Refer to Fig 89.
6. Clean the condenser and evaporator ns with compressed
air in the opposite direction to the normal air ow. If there
is a build up of greasy deposit, it can be cleaned with a non
abrasive soap solution.
