SEPARATE THE COMPRESSOR
The VFD blocks access to the compressor mounting bolts. It must
be removed before the compressor can be separated from the con-
denser. Remove the VFD from condenser using the Remove the
Controls/Drive Enclosure section on page 27. Refer to Table 20.
Table 20 — Compressor Fastener Identification
1. Disconnect the oil supply line in 2 places (Fig. 28 or 29). Cap
the oil lines and fittings.
NOTE: Compressor oil lines and fittings between the oil filter and
compressor must be kept extremely clean to prevent obstruction of
the compressor inlet bearing oil orifice. Cap all orifice lines and
fittings during disassembly. The compressor inlet bearing oil ori-
fice is located at the lubrication block on top of the compressor.
2. Disconnect the motor cooling inlet flange, the motor cooling
drain flange, optional economizer vapor line flange, and bear-
ing oil drain flange (Fig. 28 and Fig. 29). Remove the econo-
mizer muffler bracket.
3. Brace the end of the discharge pipe assembly closest to the
compressor if it has not already been removed. Place an oil
pan under the compressor flange to collect oil that may
have accumulated in the discharge pipe assembly. Unbolt
the discharge pipe assembly from the compressor. It may
also be necessary to loosen the bolts that attach the dis-
charge pipe assembly to the condenser.
4. If the cooler has been removed (not applicable for P compres-
sor), rig the suction elbow and unbolt the suction elbow at the
compressor and vaporizer vent line flanges (see Fig. 18). If
the cooler is still in place, it may be necessary to loosen the
bolts that secure the suction elbow to the cooler.
5. Carefully remove the perforated insulation cutouts that cover
the compressor lifting points. See Fig. 28 and 29. Replace the
lifting shackle thread protector after the compressor is re-
installed to prevent insulation adhesive from fouling the
threads.
6. Rig the compressor with lifting eyelets installed in the two
M30 threaded holes provided in the top of the compressor
housing (Fig. 28 and 29). Use only M30 forged eye bolts or
M30 hoist rings with a sufficient working load limit to safely
lift the compressor. The rubber vibration isolators may pull
out of the compressor mounting bracket when the compressor
is lifted off of the condenser. Applying leak detection soap
solution to the outside of the vibration isolators will make it
easier to press the isolators back into position.
7. Cover all openings.
NOTE: To reassemble, follow steps in reverse order. Connect sen-
sors and cables after major components have been secure to re-
duce the risk damaging them.

CAUTION
Do not rig the heat exchanger before the control center and
compressor are removed. The assembly has a high center of
gravity and may tip over when lifted at the tubesheet rigging
points, which could result in equipment damage and/or serious
personal injury.
