DRIVE COUPLING INSTALLATION
Refer to Figure 6-4 . For coupling installation the tools
required will be one set of Allen wrenches. All ES-8
compressors are flange-mounted to the motor
making them self-aligning, eliminating the need for
alignment procedures. Proper hub separation is s
hown in
Figure 6-4 .
CONTROL SYSTEM ADJUSTMENT
All components in the Control System are designed
and manufactured to close tolerances to help
eliminate any need for adjustments.
DANGER
DO NOT touch the electrical contacts, terminal or
leads with any part of the body or any uninsulated
metallic object. Severe electrical shock may occur.
PRESSURE VALVE ADJUSTMENT
If pressure valve adjustment is required the
adjustment procedure below should be followed:
1. Start compressor.
2. Lower line pressure (P2) until machine goes
on load.
3. Loosen hex nut on the regulator valve to
adjust machine modulation. Adjust screw in
or out until on load/off load modulation of
compressor takes place.
4. Close service valve downstream from
receiver tank. The pressure will increase
depending on the regulator valve adjustment
screw setting. Adjust screw until line pres-
sure (P2) rises to the Supervisor II prepro-
grammed off load setting. Tighten hex nut.
5. Open service valve and observe correct on
load/ off load modulation.
