Air Conditioning Operating Tips
IMPORTANT: For the most efficient operation of the air conditioning
system, operate the blower fan at either medium or high speed and then vary
the temperature control to arrive at a comfortable setting.
NEVER operate the blower fan in the medium speed position when the Air
Conditioning temperature control is in the coldest position. Failure to operate
the blower fan at a high enough speed when the air conditioner is operating
can result in evaporator icing (freeze) up and no cooling.
The blower speed and temperature control will have to be adjusted to-
gether for the most efficient cooling depending upon outside temperature.
Remember: high cooling - high fan speed. If the cab air is too cold ALWAYS
adjust the temperature control to a warmer setting before reducing the blower
speed.
Under normal operating conditions, with the cab sealed properly and the
windows and doors closed, temperatures of 10to 25 fahrenheit degrees (5.5to
13.8 celsius degrees) depending upon relative humidity) lower than the out-
side temperature can be expected. Humidity is also greatly reduced when
operating the air conditioning system, making the cab even more comfortable
to the operator.
NOTE: If you notice that the air conditioner stops working, refer to page
