MAINTENANCE
2. The pipe ends should be free of surface
scratches, gouges, dents, etc. A special finish is
not required.
JOINT INSTALLATION FOR 1 1/2" --- 4" PIPE
1. Install the retainer (1), gasket (2), and sleeve (3)
on one side of the pipe in sequence.
2. Install the remaining retainer (4) and gasket (5)
on the other pipe end.
3. Position the retainer (4) and gasket (5) to proper
pipe gap "G" as shown.
4. Slide the sleeve (3) to the gasket (5) and move
gasket (2) and retainer (1) into position as
shown. The pipe MUST be inserted to the
proper depth into both gaskets, to obtain re-
quired gap "G".
COUPLER INSTALLATION
1. Install both V couplings, encompassing the re-
tainer, gasket and sleeve. DO NOT tighten
either coupling until the entire joint has been as-
sembled. Tighten nuts as shown in Table 2. Re-
tightening of the coupler (6) will be necessary if
leakage occurs.
2. Tighten the nuts to the torque value shown in
Table 2. RECOMMENDED
TORQUE MUST BE MAINTAINED. Retighten-
ing of the coupler will be necessary if leakage
occurs.
SPECIAL NOTES
1. Assembly of the gaskets can be made easier by
dipping the gaskets in the fluid to be sealed. The
use of other rubber lubricants can be detrimen-
tal to the life of the gaskets. NEVER LUBRICATE
THE METAL PARTS.
2. Flexible joints are not intended to support end
loads caused by internal pressure or other
forces causing pipe separation.
MOTOR CONNECTION INSTRUCTIONS
1. Once a year while the equipment is discon-
nected from the power source and locked out
for maintenance, remove the cover to the motor
conduit box.

2. Inspect the rubber boots' or connections' insu-
lating materials covering the motor connections
for signs of thermal damage.
3. If boots or insulating material remain pliable and
there is no sign of damage, connections are sat-
isfactory.
4. If boot or insulating material show distress as
mentioned above, then investigate to determine
the source of thermal damage and repair the
connection as necessary.
5. Replace the damaged boot(s) with new boot(s)
as required or retape connections per National,
State or Local codes.
6. Replace the conduit cover prior to reconnecting
the power source.
Electrical shock hazard. Disconnect all power at
the source before attempting maintenance.
6.8 TROUBLESHOOTING
The information contained in the Troubleshooting
chart has been compiled from field report data and
ASSEMBLY
factory experience. It contains symptoms and
usual causes for the described problems. Howev-
er, DO NOT assume that these are the only prob-
lems that may occur. All available data concerning
the trouble should be systematically analyzed be-
fore undertaking any repairs or component re-
placement procedures.
A detailed visual inspection is worth performing for
almost all problems and may avoid unnecessary
additional damage to the compressor.
a. Check for loose wiring.
b. Check for damaged piping.
c. Check for parts damaged by heat or an electrical
short circuit, usually apparent by discoloration
or a burnt odor.
Should your problem persist after making the rec-
ommended check, consult your nearest Sullair Dis-
tributor or the Sullair Corporation.
