COLD AMBIENT OPERATION – See “Installation for
Cold Weather Operation,” page 10, and FIGURE 2–3,
page 11.
ADDITION OF OIL BETWEEN CHANGES must be
made when the oil level is at the bottom of the red range
on the gauge as read while the unit is running.
To add oil, follow these steps:
1. Be sure the unit is completely off and that no air
pressure is in the oil reservoir.
2. Disconnect, tag and lockout the power supply to
the starter.
3. Wipe away all dirt around the oil filler plug.
4. Remove the oil filler plug and add oil as required
to return the oil level to the center of the green
range.
5. Install the oil filler plug, run and check for leaks.
DO NOT OVERFILL . The quantity required to raise the
oil level from “ADD” to “FULL” is shown in
FIGURE 5–2. Repeated addition of oil between oil
changes may indicate excessive oil carry–over and
should be investigated.
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.
Compressor, air/oil reservoir, separa-
tion chamber and all piping and tub-
ing may be at high temperature during
and after operation.
Excessive oil carry–over can damage
equipment. Never fill oil reservoir
above the “FULL” marker.
LUBRICANT CHANGE PROCEDURE – Upgrading to
a longer life lubricant is essentially a very worthwhile
practice. Following are the primary steps to be com-
pleted when upgrading or changing the type of lubri-
cant.
1. Thoroughly drain system:
– Drain oil from air end and cooler while hot.
– Break low point connections and drain oil
from pipe runs.
– Dump oil from the filter and reinstall used fil-
ter.
