MAIN MOTOR HEATER

1. When the motor heater switch is in the ON
position, the motor heater will be activated
until the switch is set to OFF or the compres-
sor starts.
2. In extremely wet environments, the motor
heater should be run for 2 hours prior to start
of compressor.
3. The heater should run for 2 hours once a
month when the compressor is unused for
an extended period of time. Additionally, the
heater should be run for 2 hours prior to ini-
tial startup following an extended storage
period.
The main motor heater will be switched off
once the motor is started.
If the machine is energized and the motor
heater switch is on, the heater will be ener-
gized as long as the machine is not running
and the E-Stop is not depressed.

FAN ROTATION SWITCH

This switch controls the direction of rotation of the
cooling fan. The direction should be set to
FORWARD in warm weather. In cold weather below
32°F (0°C), the fan can be operated in REVERSE.
This will help to prevent freezing of control lines as
well as help to maintain the proper operating
temperature of the compressor. Operating the fan in
REVERSE during warm temperatures can cause
high operating temperatures and ultimately the
shutdown of the compressor.
