4.1 Fluid level check

The compressor is shipped fully charged with the proper
amount of fluid. However, it is necessary to check the
fluid level at the time of installation and during compres-
sor operation. Check the fluid level when the compressor
is in the SHUT DOWN mode (fluid level may not be visi-
ble when operating), and by looking at the sight glass on
the receiver tank (see Figure 6-5 on page 47). The full
level is at half the sight glass. Add fluid if fluid level is not
visible in the sight glass when machine is shut down.

4.2 Electrical preparation

Energized internal components are a potentially
fatal shock hazard. Disconnect all power
before performing any work on the compressor's
electrical system.
Interior electrical wiring is installed at the factory.
Required customer wiring should be done by a qualified
electrician in compliance with OSHA, National Electric
Code and/or any applicable local electrical codes. Cus-
tomer to supply power via cam-lock located on end of
enclosures. An electrical check should be made to
ensure that the first start-up will be successful. The com-
pressor and drive should be properly grounded/earthed

in accordance with applicable codes, regulations, and
requirements.
Feeder cables should be sized by the customer/electrical
contractor to ensure that the circuit is balanced and not
overloaded by other electrical equipment. The length of
wiring from a suitable electrical power source is critical
because voltage drops can adversely effect the perfor-
mance of the compressor. Refer to Table 4-1: Incoming
conductor wiring.
Table 4-1: Incoming conductor wiring
480V 45°C
380V 45°C
Parallel feeder cable connections to incoming terminal
cam-locks L1-L2-L3 should be tight and clean. These are
located on end of package. Behind the access door
located above the cam-locks is the package circuit
breaker disconnect, supplied for additional safety.
The applied voltage must conform to the motor and com-
pressor data plate ratings.
• Check incoming voltage. The incoming voltage
must match the compressor's wire rating/speci-
fications.
• Check motor starting device and overload
heater sizes.
• Check all electrical connections for tightness.
