Refer to FIGURE 5–4, page 38, for the following
instructions:
1.
To remove cannister (3) rotate tie bolt (10) coun-
terclockwise until the cannister is free of head as-
sembly (1).
2.
Remove the element (6) from the cannister. Re-
move indicator assembly (5) from the element by
inserting a screwdriver between the indicator as-
sembly and element and carefully prying down-
ward. Inspect O–ring (4) for cuts or excessive
wear and discard the element. Rinse out cannister
with clean fluid to remove any contamination.
3.
Remove O–ring (2) from the head assembly and
inspect for cuts or excessive wear. Wipe O–ring
area of the head (1) with clean cloth and after cov-
ering O–ring with oil, reinstall in the head assem-
bly. Check the indicator assembly (5) machined
bore in the head for burrs or deep scratches and
carefully smooth out if required.
4.
Install the indicator assembly (5) into the new ele-
ment. Place the element into the cannister making
sure the spring (8), washer gasket (9) and tie bolt
(10) are in proper position.
The large diameter end of the spring
should contact the new element.
5.
Place cannister as previously assembled into
head assembly and rotate clockwise until torqued
to 20 foot–pounds.
6.
If leakage appears at bottom of cannister, replace
washer gasket (9). If leakage appears at top of
cannister, replace O–ring (2). If this does not stop
the leakage, the cannister must be nicked or dis-
torted by overtorquing and should be replaced.
COMPRESSOR OIL COOLER (RADIATOR TYPE) –
(FIGURE 5–5) The air–cooled oil cooler module is re-
mote mounted. The oil cooler requires pipe and electri-
cal connection to the main compressor unit. Connect-
ing piping and wiring are furnished by the user. See
”Installation”, Section 2, page 8.
Do not obstruct the air flow to and from the oil cooler.
Allow two (2) feet clearance on all sides of the oil cooler.
See FIGURE 2–2, page 8, for cooling air flow require-
ments. Keep both faces of the oil cooler core clean for
efficient cooling of the compressor oil. Oil cooler mal-
functions may be traced by checking oil pressure drop
through the cooler; check by installing pressure gauges
at fittings in the inlet and outlet oil piping near the end

of the cooler. At normal operating air service pressures
(65 to 150 psig), with the unit warm, a pressure drop of
2 to 25 psig can be expected between the inlet and out-
let side of the cooler. The controller will show the reser-
voir temperature which is the air temperature in the res-
ervoir and the approximate oil temperature into the
thermal mixing valve.
An oil filler stand pipe and plug must be located in the
piping on the oil cooler module for ease of filling the oil
cooler when it is mounted at a distance from the com-
pressor unit. When filling a remotely mounted oil cooler,
be sure all lines to and from the compressor unit are
also filled to prevent excessive drawdown of the oil sup-
ply in the oil reservoir. A vent line should be installed be-
tween the oil cooler and compressor oil reservoir as an
aid in filling and to prevent siphoning.
Failure to remove condensate from an
idle cooler in freezing temperatures
will cause permanent cooler damage.
Drain condensate after system shut-
down. It is the owner/operator’s re-
sponsibility to ensure that conden-
sate has been drained and cooler
dried out to prevent cooler damage.
HEAT EXCHANGER (OIL) PIPING – All remote ele-
vated cooler applications must be sent through Engi-
