MAINTENANCE
39
7.1 GENERAL
As you proceed in reading this section, it will be
easy to see that the Maintenance Program for the
air compressor is quite minimal yet important. The
use of the service indicators provided for the fluid fil-
ter, air filter and fluid separator, will alert you when
service maintenance is required. When the mainte-
nance message is displayed by the Supervisor
Controller
TM
, maintenance for that specific item is
required. See instructions for each item in Section
7.7, Parts Replacement and Adjustment proce-
dures.
7.2 DAILY OPERATION
Prior to starting the compressor, it is necessary to
check the fluid level in the sump. Should the level
be low, simply add the necessary amount. If the
addition of fluid becomes too frequent, a simple
problem has developed which is causing this
excessive loss. See the Troubleshooting Section
(7.8) under Excessive Fluid Consumption for a
probable cause and remedy.
After a routine start has been made, observe the
Supervisor control panel and be sure it monitors the
correct readings for that particular phase of opera-
tion. After the compressor has warmed up, it is rec-
ommended that a general check of the overall com-
pressor and Supervisor be made to assure that the
compressor is running properly.
DO NOT remove caps, plugs, and/or other com-
ponents when compressor is running or pres-
surized.
Stop compressor and relieve all internal pres-
sure before doing so.
7.3 MAINTENANCE AFTER INITIAL 50 HOURS OF
OPERATION
After the initial 50 hours of operation, a few mainte-
nance requirements are needed to rid the system of
any foreign materials if any. Perform the following
maintenance operations to prevent unnecessary
problems.
1. Clean the return line strainers.
2. Clean the return line orifices.
3. Change the fluid filter element.
4. Clean the control line filters.
7.4 MAINTENANCE AFTER 1000 HOURS
After 1000 hours of operation, it will be necessary to
perform the following:
1. Clean the return line strainers.
2. Lubricate the Sullicon Control linkage.
3. Replace the fluid filter element.
7.5 FLUID CHANGE
Standard models are filled with the long life lubri-
cant Sullube.
Sullube should be changed under the following con-
ditions, whichever occurs first:
1. Every 8000 hours.
2. Once a year.
3. As indicated by fluid analysis.
A fluid sample analysis at every 4000 hours is rec-
ommended. Return fluid to Sullair Corporation in
Michigan City for free analysis. To facilitate this, a
sample bottle is included with the compressor.
7.6 SEPARATOR MAINTENANCE
Replace the separator elements when a message is
displayed or after one (1) year, whichever comes
first. The separator elements must be replaced.
DO
NOT clean the separator elements.
