WARNING
!
Before doing compressor/dryer maintenance,
disconnect compressor from power source and
lock out power source. Isolate compressor/dryer
from line pressure by closing recommended dis-
charge shut---off valve and releasing all internal
pressure from compressor/dryer.
1. Insert a 100mm maximum length, 6mm diame-
ter pin into the radially drilled hole in the separa-
tor cap. Loosen, unscrew counterclockwise and
remove the cap.
2. Pull out the old element by gripping the end of
the element with channel lock pliers or a similar
tool.
3. Install new o---rings on separator cap and sepa-
rator element filter and oil lightly to make installa-
tion easier.
4. Insert and push the new element into place.
5. Reinstall the cap. Hand---tighten using a 100mm
maximum length, 6mm diameter pin in the ra-
dially drilled hole.
DRIVE COUPLING INSTALLATION
Refer t o Figure 9 --- 4. For coupling installa tion 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 sepa-
r a t ion is s h ow n in Fig u r e
CONTROL SYSTEM ADJUSTMENT
All components in the Control System are de-

cur.
PRESSURE REGULATOR ADJUSTMENT
If pressure regulator adjustment is required, the
adjustment procedure below should be followed:
1. Start compressor.
2. Lower line pressure (P
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 pressure (P
Supervisor II preprogrammed off load setting.
Tighten hex nut.
5. Open service valve and observe correct on load/
off load modulation.
INLET CONTROL VALVE
