7. Add oil, if necessary, to bring level to the center of
the green range on the gauge.
On unloaded operation and after shutdown some oilwill
drain back into the oil reservoir and the oil level gauge
will read “FULL.” DO NOT DRAIN OIL TO CORRECT.
On the next start, oil will again fill the system and the
gauge will indicate operating at the proper level. DO
NOT OVERFILL as oil carryover will result. The quanti-
ty of oil required to raise the oil level from “ADD to
“FULL” is shown in FIGURE 5-6, page 48. Repeated
addition of oil between changes may indicate exces-
sive oil carryover and should be investigated.
Use only CLEAN containers and funnels so no dirt en-
ters the reservoir. Provide for clean storage of oils.
Changing the oil W-llbe of little benefit if done in a care-
less manner.
~CAUTION
Excessive oil carry-over can damage
equipment.
Never fill oil reservoir
above the “FULL” marker.
COMPRESSOR OIL FILTER (FIGURE 5-1) - This
screw on oil filter is a vital part in maintaining a trouble-
free compressor, since it removes dirt and abrasives
from the circulated oil. The oilfilter relief valve is located
in the oil filter head. The relief valve opens in the event
the element becomes dirty enough to block the flow of
oil.
~cAuTlON
Improper oil filter maintenance will
cause damage to equipment. Replace
filter element every 1000 hours of op-
eration. More frequent replacement
could be required depending on oper-
ating conditions. A filter element left
in service too long may damage
equipment.
Use onlv the replacement element shown on the filter
tag or refer to the parts list for the part number. Use the
following procedure to
not disturb the piping,
replace the filter element. Do
~DANGER
Air/oil under pressure will cause
severe personal injury or death. Shut
down compressor, relieve system of
all pressure, disconnect, tag and
lockout power supply to the starter
before removing valves, caps, plugs,
fittings, bolts, and filters.
~DANGER
Compressor, air/oil reservoir, separa-
tion chamber and all piping and tub-
ing may beat high temperature during
and after operation.

Stop the unit and be sure no air pressure is in the
oil reservoir.
Remove the spin-on element.
Clean the gasket face of the filter body.
Coat the new element gasket with clean lubricant
used in the unit.
Screw the new element on the filter body and tight-
en by hand. DO NOT OVERTIGHTEN THE ELE-
MENT.
Run the unit and check for leaks.
COMPRESSOR OIL COOLER - RADIATOR TYPE
(FIGURE 1-5, page 3) - The oil cooler motor and fan
is mounted on the oil cooler module; air is exhausted
through the oil cooler and away from the unit. Do not
obstruct air flow to and from the oil cooler. Allow a mini-
mum of three (3) feet clearance around the cooler.
Keep both faces of cooler core clean for efficient cool-
ing of compressor oil.
THERMAL CONTROL (THERMOSTATIC MIXING)
VALVE (FIGURE 5-7, page 50) is installed in system
as shown in FIGURE 5-1, page 43. This valve is used
to control temperature of the oil in both air-cooled ra-
diator and water-cooled heat exchanger type oil cooler
systems, On start-up with unit cold, element is open to
bypass, allowing oil to pass directly from the reservoir
to compressor during warm-up. As oil warms, element
gradually closes to the bypass allowing more of the oil
from the cooler to mix with oil from the bypass.
