1. Disconnect the tubes at the tops of the sight
glass assemblies.
2. Unscrew male connector (for left-side glass), or
the straight thread tube connector (for right-side
glass) from sight glass/orifice blocks.
3. Remove used filter assembly, and replace with
new assembly.
4. Coat/lubricate the O-rings will silicone grease.
5. Reattach the connectors to the sight glass/orifice
blocks.
DIFFERENTIAL
PRESSURE REGULATOR
ADJUSTMENT
. The differential pres-
sure regulators are adjusted by loosening the jam
nut on the end of the cone shaped cover of the
pressure regulator. When the jam nut is loose, turn
the adjusting screw clockwise to increase or coun-
terclockwise to decrease the setting.
Above 100 psig (6.9 bar), the spiral valve regulator
should allow pressure to flow into the chamber of
the spiral valve actuator. The spiral valve should
start to rotate at this time.
At approximately 108 psig (7.5 bar), the Sullicon
regulator should allow pressure to flow into the con-
trol chamber of the Sullicon Control. The Sullicon
Control level should start to move at this time. Cycle
the Control System several times and recheck all
pressure settings.
COMPRESSOR DRIVE COUPLING
The performance and life of couplings depend
largely upon how you install and maintain them.
Before installing couplings, make certain that
foundations of equipment to be connected meet
requirements of
must be aligned after installation and prior to ini-
tial start-up of the compressor.
The use of stainless steel shims under the motor
feet is recommended. Measuring misalignment and
positioning equipment within alignment tolerances
is simplified with an alignment computer. These cal-
culations can also be done graphically or mathe-
matically.
ANNUAL MAINTENANCE- DRIVE COUPLING
Disconnect all power at source before attempting
maintenance or adjustments.
from
are exceeded,
realign coupling to installation limits.
2. Check outer blades of discpacks near bushings
for fatigue cracks. Discpacks can be checked
while coupling is in operation by using a strobe
light. Replace cracked discpacks and recheck
alignment. A slight bowing or “S”-like distortion is
normal.
3. Check tightening torques of all drive bolts.
Standard mechanics tools, torque wrenches, a
straight edge and feeler gauges or dial indicators
and brackets and micrometers are required to
install couplings. A 17mm end wrench is required
for shrink disc locking screws. For best results use
a dial indicator to check final alignment and make
certain bolts are tightened to the required elonga-
tion or torque listed in
The drive bolts have been factory tightened to the
required elongation indicated in
, and should not be disturbed.
