SEPARATE THE VAPORIZER FROM THE CONDENSER
The VFD mounting brackets (Fig. 30 and 31) extend beyond the
outboard edge of the tubesheet. The vaporizer extends beyond the
perimeter of the condenser tubesheet.
1. Cut the vaporizer hot gas supply line near the oil concentrator
(Fig. 30 and 31).
2. Cut the vaporizer hot gas return line (Fig. 32).
3. Cut the bearing oil drain line near the oil sump (Fig. 32).
4. Unbolt the vaporizer vent line flange shown in Fig. 32. (Cut
for P compressor.)
5. Cut the oil supply line as shown in Fig. 32.
6. Cut the oil reclaim line as shown in Fig. 32.
7. Disconnect all wires and cable leads to the vaporizer assem-
bly (see Fig. 33) including:
a. oil sump temperature sensor
b. oil sump pressure cable and oil pressure leaving filter
cable
c. oil reclaim cable
d. vaporizer heater cable in the vaporizer heater junction
e. oil pump cable
f. oil sump heater conduit from its junction box
(Fig. 30 and 31)
g. vaporizer temperature sensor (Fig. 30 and 31)
8. Rig the vaporizer with the lifting points on the vaporizer
mounting bracket and remove the 4 bolts that secure it to the
9. Cover all openings.
NOTE: To reassemble, follow steps in reverse order. Connect sen-
sors and cables after major components have been secured to re-
duce the risk damaging them.
Step 4 — Install VFD
1. Install terminal box frame mounting studs into tapped holes
using short threaded end (see section E-E in Fig. 34 and 35).
Do not exceed 120 ft-lb (163 N-m).
2. Install thermal insulators, insulation frame assembly, and ter-
minal box frame prior to attaching motor power cables.
3. Torque motor terminals to 45 to 55 ft-lb (61 to 75 N-m).
4. There may be 1 or 2 motor power cables per terminal iden-
tified as T1, T2 and T3. Position motor end lugs on termi-
nal studs with Belleville washer located against the front
terminal lug with the convex side facing toward the front
terminal nut. Clinch the 2 cables together with wire ties
before tightening terminal nuts. Install front terminal nut
finger tight. Hold front terminal nut stationary while tight-
ening rear terminal nut to 45 to 50 ft-lb (61 to 68 N-m).
See Fig. 36 and 37.
