2.1 LOCATION OF COMPRESSOR
The ES--11 Series compressor package may be
placed on any level surface capable of supporting its
weight and rigid enough to maintain a level com-
pressor frame. The compressor frame must be lev-
eled and secured with foundation bolts, and full uni-
form contact must be maintained between the frame
and foundation. No piping loads shall be transmitted
to the compressor at the external connections.
2.2 VENTILATION AND COOLING
Select a location to permit sufficient unobstructed
air flow in and out of the compressor to keep the op-
erating temperature stable. The minimum distance
that the machine should be from surrounding walls
and ceiling is what is needed for service and three
(3) feet (914mm) or more from the compressor fluid
cooler.
For water--cooled compressors, it is necessary to
check the cooling water supply. The proper water
f low s hould be as s hown in Table 1 in t his s ec t ion.

Table 2 indic at es t he v ent ilat ion r equir em ent s nec -
essary to keep the compressor running at a normal
operating temperature. The fan air requirement is
the volume of air which must flow through the com-
pressor for proper ventilation. The specified heat
rejection requirement is the amount of heat that is
radiated by the compressor. This heat must be re-
moved to assure a normal operating temperature. It
is possible to use this heat for space heating, provid-
ing no additional pressure drop is created across the
fan. Consult a Sullair office for assistance in utilizing
this heat.
DO NOT install a water--cooled or an air--cooled/af-
tercooled compressor where it will be exposed to
temperature less than 32

NOTE
Be certain the watercooler drain plugs are in place
prior to start--up.
2.3 SERVICE AIR PIPING
Service air piping should be installed as shown in
F igur e 2 -- 1 . A s hut -- off v alv e s hould be ins t alled t o
isolate the compressor from the service line. Also
notice that the service line should be equipped with
water legs and condensate drains throughout the
system.
WARNING
!
“The Plastic Pipe Institute recommends against the
use of thermoplastic pipe to transport compressed
air or other compressed gases in exposed above
ground locations, e.g. in exposed plant piping.” (I)
Sullube 32 should not be used with PVC piping sys-
tems. It may affect the bond at cemented joints. Cer-
tain other plastic materials may also be affected.
(I) Plastic Pipe Institute, Recommendation B,
Adopted January 19, 1972.
2.4 FLUID LEVEL CHECK
A fluid sight glass on the sump housing serves as a
level indicator. During operation, the level should
not exceed 1/4 to 1/2 of the sight glass. With the
compressor shut down the level will rise to the bot-
tom of the fluid fill plug located above the sight glass.
2.5 ELECTRICAL PREPARATION- STANDARD
ELECTRO/MECHANICAL
Interior electrical wiring is performed at the factory.
Required customer wiring is minimal, but should be
done by a qualified electrician in compliance with
OSHA, National Electrical Code, and/or any other
applicable State, Federal and local electrical codes
concerning isolation switches, fused disconnects,
etc. Sullair provides a wiring diagram for use by the
installer.
NOTE
Customer must provide electrical supply power
disconnect within sight of machine.
A few electrical checks should be made to help as-
sure that the first start--up will be trouble--free.
WARNING
!
Lethal shock hazard inside. Disconnect all power
at source before opening or servicing.
1. Check incoming voltage. Be sure that compres-
sor is wired for the correct incoming voltage.
