OUTDOOR INSTALLATION (SHELTERED)
Many times a compressor must be installed outside
due to available space or other jobsite conditions.
When it is necessary, there are certain items that
should be incorporated into the system to help
ensure trouble-free operation. The unit must be
purchased with a TEFC motor. The standard
machine has NEMA 4 rated controls, which are
watertight.
4.3 SERVICE AIR PIPING
Review carefully the total air system before installing
a new compressor. Items to consider for the total air
system include liquid carryover, pipe sizing,and the
use of a receiver. The installation of a drip leg or
multiple drip legs, installation of a line filter(s) and the
installation of isolation valve or valves.
PIPE SIZING
Pipes should be sized as a minimum to match the
dimensions of the compressor’s discharge
connection. All piping and fittings should be rated for
the discharge pressure.
USE OF AUXILIARY RECEIVER
An auxiliary receiver should be used in cases where
large demand swings are expected.
ISOLATION VALVE(S)
If isolation of the compressor from the service lines is
required, isolation valves should be installed close to
discharge of the compressor. They should be
installed with drip legs that drain sloping downward
from the base in order to drain properly. Install a vent
to the piping downstream of the compressor outlet
connection.
When two compressors are operated in parallel,
proved an isolation valve and a drain trap for each
compressor before the common separator/sump.
A built-in aftercooler reduces the discharge air
temperature below the dew point. For most ambient
conditions, considerable water vapor is condensed.
To remove the condensation, each compressor with
built-in aftercooler is supplied with a combination
condensate separator/trap. A drain line should be
installed on the condensate drain.
4.4 COUPLING ALIGNMENT
CHECK
No coupling alignment check is required. For
maintenance requirements refer to parts
replacement and adjustment procedures in the
maintenance section of this manual.
4.5 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 sump tank. To be
able to see the fluid level it may be necessary to start
the machine and build the sump tank pressure up to
10/20 psi and then shut down. If no fluid level is seen
in the sight glass add fluid to the center of the glass.
Do not overfill in any case. When a complete fluid
change is performed, fill the sump tank to the
maximum allowable fluid level, which is center of the
sight glass.
NOTE
Discharge air contains a very small amount
of compressor lubricating oil, and care
should be taken to ensure that this oil would
not interfere with downstream equipment.
Downstream filters and an air dryer can
remove any carryover.
NOTE
VSD compressors are NEMA 12 rated which
makes them unsuitable for outside instala-
tion or in locations where they will be
exposed to outside elements. All ship loose
are NEMA1 rated.
NOTE
For low-volume systems that do not require
an auxiliary receiver, compressor response
time may need to be adjusted. Consult the
Sulliar Service Department for assistant.
