Safety Steps (Continued)
1. Make sure repairs are done in a clean, dry,
well lighted and ventilated area.
2. When cleaning, use air pressure less than
30 psig (2.1bar). Also use effective chip
guarding and personal protective
equipment per OSHA standard 29 CFR
1910.242 (b).
3. Relieve all internal pressure prior to
opening any line, fitting, hose, valve, drain
plug, connection or other component, such
as filters and line oilers, and before
refilling optional air line anti-icer systems
with antifreeze compound.
4. Keep sound reducing material, any
external surfaces of the air compressor or
internal surfaces of the enclosure free from
fluids and build-up. Clean with water
based industrial cleaner or steam clean as
necessary. Remove then replace sound
reducing materials as needed to clean all
surfaces. Immediately replace any sound
reducing material with torn or punctured
protective covering to prevent
accumulation of liquids or build-up inside
the material. NEVER use flammable
solvents for cleaning purposes.
5. Keep electrical wiring, including all
terminals and pressure connectors in good
condition. Replace any wiring that has
cracked, cut, or otherwise damaged
insulation. Replace terminals that are
worn, discolored or corroded. Keep all
terminals and pressure connectors clean
and tight.
6. Keep all body parts and any hand-held
tools or other conductive objects away
from exposed live parts of the electrical
system. When making repairs or
adjustments, stand on a dry, insulated
surface and DO NOT contact any other
portion of the compressor
.
7. DO NOT leave compressor unattended
with exposed electrical components. Be
sure to tag and disconnect all power if
temporary absence is necessary.
Compressor components can
become hot during operation.
Avoid bodily contact with hot
liquids, hot surfaces and sharp
edges and corners, or burns or
personal injury could result.
Lubricating Oil
To avoid water condensation during operation,
keep oil temperature between 160˚ - 190˚ F
(70˚ - 88˚ C). Failure to do so causes pump
damage. Contact Polar Air service if temperature
drops below 160˚ F (70˚ C).
Changing Oil
1. Shut down compressor and allow machine
to set for 5-10 minutes.
Air/Oil Separator tank is a
pressurized component. To
avoid serious injury, be
sure system pressure is
relieved before removing
fill plug. Be aware oil
temperature may be very
hot. Use caution when opening fill plug.
2. Drain oil completely. Be sure to include
oil in system piping, cooler and air/oil
separator tank. Close drain valve.
3. Remember to remove and change oil filter,
taking care to avoid hot oil during
replacement.
4. Open oil fill port and add new oil.
Oil Capacities:
7.5– 10 HP – 5 liters (1 gal/2.5 pints)
15 – 20 HP – 6 liters (1 gal/4.6 pints)
25 – 30 HP – 11 liters (2 gal/7.25 pints)
40 – 60 HP – 20 liters (5 gal/2.25 pints)
75 – 100 HP – 30 liters (7 gal/7.4 pints)
125 – 150 HP – 70 liters (18 gal/4 pints)
175 – 200 HP – 80 liters (21 gal/1 pint)
DO NOT OVERFILL. Residual
oil may still be in the compressor. The above
capacities can be used for guidelines, but use the
upper arrow fill line on the sight glass (See page
7). Over filling causes oil to blowout the inlet
valve and through the air filter, also oil could
push past the separation system resulting in oil in
the air lines.
