4.1 MOUNTING OF VACUUM SYSTEM
A foundation or mounting capable of supporting the
weight of the machine, and rigid enough to maintain
the Vacuum System frame level and the vacuum
unit in alignment is required. The Vacuum System
frame must be leveled and secured with foundation
bolts, and full uniform contact must be maintained
between the frame and foundation. No piping loads
shall be transmitted to the compressor at the exter-
nal connections.
4.2 VENTILATION AND COOLING
For air-cooled Vacuum Systems, select a location to
permit sufficient unobstructed air flow in and out of
the system to keep the operating temperature sta-
ble. The minimum distance that the machine should
be from surrounding walls is four (4) feet (1219mm)
and preferably six (6) feet (1829mm) or more at the
end of the machine above the cooler.
For water-cooled machines, it is necessary to check
the cooling water supply (refer to Table 4A).
Table 4B indicates the ventilation requirements nec-
essary to keep the machine running at a normal
operating temperature. The fan air requirement is
the volume of air which must flow through the
machine for proper ventilation.
The specified heat rejection requirement is the
maximum amount of heat that will be radiated by
the machine. This heat must be removed to assure
a normal operating temperature. It is possible to
use this heat for space heating, providing no addi-
tional pressure drop is created across the fan.
Consult a Sullair representative for assistance in
utilizing this heat.
DO NOT install a water-cooled machine where it
will be exposed to temperature less than
32ºF(0ºC).
4.3 VACUUM SYSTEM PIPING
A shut-off valve should be installed to isolate a
machine from the vacuum system. The system's
lines should be equipped with water legs and con-
densate drains throughout the system.
It is recommended that the discharge of the
Vacuum System be piped to an open and well ven-
tilated area.
4.4 COUPLING ALIGNMENT CHECK
With the vacuum unit directly flange mounted to its
drive, the coupling supplied with your machine is
always properly aligned for operation. However,
prior to start-up and handling, it is advised to
recheck the coupling hub gap.
4.5 FLUID LEVEL CHECK
The Sullair Vacuum System is also supplied with
Table 4A - Water Flow Requirements (Water-cooled)
HORSEPOWER
WATER FLOW
GPM Liter/Min
30 3.1 11.7
40 3.9 14.8
50 4.7 17.9
The proper water flow should be as follows
when using 80ºF (27ºC) water (water pressure
should be between 15 and 75 psig [103 and
517kPa]).
