Section 4-Installation - Sullair E900H User Manual

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 compressor operation. Check the fluid level
when the compressor is in the SHUT DOWN MODE
(fluid level may not be visible when operating), and
by looking at the sight glass on the receiver tank
(See Figure 6-5). 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
WARNING
Energized internal components are a poten-
tially 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. Customer 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 compressor and drive should
be properly grounded/earthed in accordance with
applicable codes, regulations, and requirements.
Section 4
INSTALLATION
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 performance of the
compressor. Refer to Table 4-1: Incoming Conductor
Wiring.

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
compressor data plate ratings.
1. Check incoming voltage. The incoming volt-
age must match the compressor's wire rat-
ing/specifications.
2. Check motor starting device and overload
heater sizes.
3. Check all electrical connections for tightness.
