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.
8. Insert the new separator elements (P/N's
250034---116 and 250042---862) into the sump
taking care not to dent them against the tank
opening.
9. Clean the underside of the receiver/sump tank
cover and remove any rust. Paint surface with an
epoxy paint. DO NOT REMOVE GASKET STA-
PLES.
10. Replace the cover plate, washers and caps-
crews. Torque to 55 ft.---lbs. (75 Nm).
11. Reconnect all piping making sure return line
tubes extend to the bottom or 1/4" (6mm) above
the bottom of the separator element. This will as-
sure proper fluid return flow to the compressor.
12. Clean both return line strainers before restarting
the compressor.

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
operating pressure which is stamped on the com-
pressor serial number nameplate. The following ex-
planation applies to a typical installation with a de-
sired operating range of 100 to 110 psig (6.9 to 7.6
bar). This information will apply to a compressor
with any other operating range except for the stated
pressures.
Remove the pressure switch cover. With the shut---
off valve closed (or slightly cracked open) start the
compressor. Observe the line pressure gauge and
pressure switch contacts. When the line pressure
reaches the desired pressure, the pressure switch
contacts should open. If the pressure switch con-
tacts do not open or they open prior to the desired
pressure, the pressure switch setting will require ad-
justment ( r ef er to Figur e
DANGER
