2.7 SHIPPING BOLT REMOVAL
The unit is shipped with a bolt in the motor sup-
port to prevent possible belt damage caused by
bouncing during shipment. This bolt must be
removed prior to checking motor rotation or oper-
ating the unit.
In addition, a jackscrew is located under the base
and offers support to the motor during shipment.
This jackscrew must be loosened as far as possi-
ble without removing it prior to operating unit. A
locknut is provided to keep the jackscrew in
place.
Locate the shipping bolt and jackscrew in the motor
support as shown in Figure 2.7-1 and remove the
shipping bolt.
2.8 ROTATION CHECK
Locate the rotation decal on the motor and check for
correct rotation. The correct rotation when viewed
from opposite the drive end on the motor is clockwise.
If compressor is operated in the opposite direc-
tion of rotation, airend damage can result and is
not warrantable.
For the compressor motor rotation check, the motor
jogging should be as short a time as possible.
1. Assure that the Start/Stop button is in the stop
(depressed) position.
2. Check coolant level. To check coolant level, slowly
loosen the fill plug one complete turn. As the fill plug
is unscrewed approximately one turn, a small amount
of pressure may be released. Do not remove the fill
plug until all pressure has been vented. Once
pressure is vented, finish removing the fill plug. The
proper coolant level is when the coolant is at the top
of the fill port. Add coolant if necessary.
