Installation
Caution
Never move the unit by pushing or forking against
the separat or shell or its mounting supports.
Removing the skid
If the unit is rigged into place, you can remove the skid
by taking off the nuts and bolts that are fastening the unit
mounting supports to the skid before lowering the unit
onto the mounting surface.
If the unit is skidded into place, perform the following steps:
1. Remove the cross mem bers from the skid
2.
Remove the nuts anchoring the unit to the skid.
3.
Using a 10-ton
jack under the separator, raise the unit
at the compressor end until it clears the two
mounting
bolts.
4.
Spread the skid to clear the unit mounting support,
then lower the unit to the surface.
5. Repeat proced ure on opposite end.
Checking the motor/compress or
rota tion
Warning
Make sure coupling hubs are tightened to the shaft
before rotating the motor to prevent them from
coming loose and possibly causing serious injury or
death.
Warning
Injury may occur if loose clothing or hair becomes
entangled on the spinning motor shaft.
Compressor rotation is
clockwise when facing the
end of the compressor
shaft. Do not, under
any
ci
rcumstance, attempt to
check the motor rotation
with the coupling center

section installed, because this may result in damage to the
com pressor. Bump the motor to check for correct com-
pressor rotation. After verifica
-
tion, install disc drive spacer, as
applicable.
Compressor/motor
coupling installation
HPS compressors are primarily de-
signed for connecting to an
electric
drive motor using a
tunnel mount.
If the application requires it, the
compressor can also be driven with
a foot-mounted motor. The tunnel
mount ensures correct alignment of the compressor and
motor so that the shaft seal and coupling operate correctly.
Figure 3: Direction of rotation
Figure 4: Motor tunnel
The rotor and bearing design set limitations must not be
exceeded (See CoolWare). Refer to Compressor Control
Panel instructions in
090.040-O, Quantum HD Control Pan-
el
for additional information on setpoint limits.
No align‑
ment is required in the field.
See
Installing the coupling
Figure 5: Coupling
1. Install the motor and compressor
coupling hubs and
keys on their respective shafts. Ensure that they can
slide horizontally so that after installing the
disc packs,
no axial stress is transferred to the disc packs by a
stuck coupling hub. Use no lubricants.
2. Rotate both hubs so that the keys are 180° opposed.
