Mounting Of Compressor; Ventilation And Cooling; Service Air Condensate Piping - Sullair DR13 125H Operator's Manual And Parts List

2.1 MOUNTING OF COMPRESSOR

The compressor package should be placed on a
surface or foundation that is capable of supporting
its weight, while remaining level and free of deflec-
tions which may affect the driveline mounts or the
inboard pipework.
If the package is to be secured to a foundation, it is
recommended that the package frame be leveled
and secured to the foundation with adequate an-
chorage, and that a good grade grouting be used
to insure full contact between the load bearing sur-
faces. Use 3/4" (19mm) foundation bolts.
The DR compressor/motor driveline is self---al-
igned by the use of a rigid distance piece and sup-
ported by flexible vibration isolation mounts. Poor
leveling or excessive deflections may adversely af-
fect the operation and longevity of these devices.
No piping loads or moments should be transmitted
to the air and water connections provided with the
package.

2.2 VENTILATION AND COOLING

Select a location that allows an unrestricted flow of
ambient ventilation
(approximately 18,000 CFM). The maximum allow-
able ambient temperature is 115_F (46_C). Heat
rejection to the surrounding environment will be up
to 20% greater than the motor horsepower (this is
Figure 2 ---1 Service Air Piping (Typical)
air through the package
because of the latent heat of condensation of the
moisture removed from the intake air and the heat
from the motor inefficiency). The 200HP model will
discharge up to 615,000 BTU/hr to the surrounding
environment (smaller models correspondingly
less).
Maintain a 3ft. (914mm) minimum separation be-
tween the package and any surrounding walls.
Note that the electrical enclosure has a 32.5 in
(826mm) access door hinged on its right side.
WARNING
!
Note that the cooling air intake to the package and
the hot air discharge are both on top of the pack-
age. There should be no restriction to the free
flow of cooling air and discharge air, and care
should be taken to ensure that cooling air and dis-
charge air remain separate.
If ductwork is installed, the total restriction on in-
take and outlet combined must not exceed 0.12 in
H O (30 Pascals).

2.3 SERVICE AIR CONDENSATE PIPING

It is recommended that service air piping be in-
stalled as shown in Fig 2---1. A shut---off valve
should be included to isolate the package from the
supply line as required. The use of water legs and
