7. Scrape the old gasket material from the cover and
flange on the sump. Be careful not to let the
scraps fall in the sump.

CONTROL SYSTEM ADJUSTMENT
Refer to Figures 6-4 and 6-5. Prior to adjusting the
control system, it is necessary to determine the de-
sired operating pressure range and also the maxi-
mum pressure at which your compressor is to oper-
ate. The pressure must not exceed the maximum op-
erating pressure which is stamped on the compres-
sor serial number nameplate. The following explana-
tion applies to a typical installation with a desired op-
erating range of 100 to 110 PSIG(689 to 758kPa).
This information will apply to a compressor with any
other operating range except for the stated pres-
sures.
Remove the appropriate panels and covers to the
pressure switch, pilot valve, and pressure regulator.
With the shut-off valve closed (or slightly cracked
open) start the compressor. Observe the line pres-
sure gauge and pressure switch contacts. When the
linepressurereaches the desired pressure, thepres-
sure switch contacts should open. If the pressure
switch contacts do not open or they open prior to the
