or danger of shifting from outside vibration or moving
vehicles may require the use of mounting bolts and
shims to provide uniform support for the base. Belt
alignment and tension should be checked after installa-
tion. (For information on belt alignment and tension see
Section 7, page 1.)
OIL RESERVOIR DRAIN -The oil drain is piped from the
botTom of the reservoir to the side of the frame. This drain
is approximately 2 inches above the floor level. If this is
not sufficient to conveniently drain the oil some other
methods of providing drain are:
1. Elevate the comPressor unit on a suitable structure
to
obtain the deSired drain height,
~CAUTION
If the compressor unit base is raised
above floor level, the space between
the floor and the base bottom must be
closed with solid material all around to
prevent recirculation of hot air from the
oil cooler end and over temperature
operation.
2. Construct an oil sump or trough below the floor
level and pump or bail the drained oil.
3. Pump oil from the reservoir filler opening or drain
to a container.
ENCLOSURE - The compressor, electric motor, oil
cooler and afTercooler are mounted inside the enclosure.
Service doors are provided for maintenance access. Be
sure to allow enough space around the unit for the doors
to open completely.
Any of the enclosure doors maybe removed by opening
the door and lifting it up slightiyto disengage the hinges.

~DANGER
Do not operate compressor with fan
and belt guard removed. Exposed fan
and belts may cause injury to person-
nel.
The motor inspection/air filter service panel is held by
two latches and lifts away from the enclosure. The air
outlet panel is attached by screws to the enclosure and
is not readily removable.
INSTALLATION FOR COLD WEATHER OPERATION
- It is recommended that the unit be installed inside a
shelter that will be heated to temperatures above freez-
ing (32"F, O"C). This will eliminate many of the problems
associated with operating units in cold climates, such as
freezing in control lines and downstream of the cooler.
Refer to Engineering Data Sheet 13-9-411 for the ad-
vantages of using the heat recovered from rotary com-
pressors. This heat recovery could easily pay for an
adequate shelter for the unit.
When an outside installation must be made, the precau-
tions required will depend on how severe the environ-
ment. The following are general guidelines for outside
installations:
Cold Weather (Down To + 10"F)
1. Be
sure
all drains, traps and control lines including
pressure transducer lines are heated to avoid freez-
ing of condensate. Heat tape with thermostat con-
trol is generally satisfactory for this purpose and
