INSTALLATION AND BREAK-IN PROCEDURES (Cont.)
AWARNING
EXCESSIVE VIBRATION MAY WEAKEN THE
AIR TANK AND CAUSE AN EXPLOSION. THE
OUTFIT MUST BE MOUNTED AS DESCRIBED
AND ILLUSTRATED BELOW.

The air compressor must be bolted to the floor.
Bolting holes are provided in the base feet.
Mount the air compressor on a solid level founda­
tion with no strain to the air tank feet. Solid shims
may be used if necessary.
Piping
ACAUTION
Plastic or PVC pipe is not designed for use with
compressed air. Regardless of its indicated pres­
sure rating, plastic pipe can burst from air pres­
sure. Use only metal pipe for air distribution lines.
If a pipe line is necessary, use pipe that is the same size
as the air tank valve. Piping that is too small will restrict
the flow of air. If piping is over 100 feet tong, use the next
larger size. Bury underground lines below the frost line
and avoid pockets where condensation can gather and
freeze. Apply pressure before underground lines are
covered to make sure all pipe joints are free of leaks.
Lubrication and Oil
ACAUTION
Compressors are shipped without oil. Do not at­
tempt to operate №is air compressor without first
adding oil to the crankcase.
Place unit on a level surface. Remove oil fill plug and
slowly add a special compressor oil such as Sears 9-
16426or SAE-20-20W SF motor oil until it is even with the
top of the oil fill
hole. {It must not be allowed to be lower than 3/8" - 6
threads down - f rom the top.) When fi II ing the crankcase,
the oil flows very slowly. If the oil is added too quickly,
it will overflow and appear to be full. (Crankcase oil
capacity is 16 fluid ounces.) Under winter-type condi­
tions use SAE10W oil. (Multi-viscosity oil -10W30 - will
leave carbon deposits on critical components reducing
performance and compressor life.) Replace oil fill plug.
Wiring Instructions
AWARNING
IMPROPER GROUNDING CAN RESULTIN ELEC­
TRICAL SHOCK. WIRING OF THE PRESSURE
SWITCH, ELECTRIC MOTOR AND MANUAL ON/
OFF SWITCH SHOULD BE DONE BY A LICENSED
ELECTRICIAN
IN ACCORDANCE WITH NA­
TIONAL AND LOCAL CODES AND ORDINANCES.
To prevent added current draw and motor overheating
we recommend the use of 12 gauge (AWG) wire, not
exceeding a 70 foot length. The wire must be rated at a
minimum temperature of 75® C.
When connect! ng wires, make surethat:(1)the electrical
box is large enough; (2) service is of adequate amperage
rating: (3) the supply line has the same electrical charac­
teristics (voltage, cycles and phase) as the motor; (4) the
line wire is the proper size and (5) no other equipment is
operated from the same line. Various national and local
codes and standards have been set up covering elec­
trical apparatus and wiring. These should be consulted
and observed. Our recommended wire sizes may be
smaller than the minimum set up by local ordinances. If
so, the larger size wire should be used to prevent
excessive line voltage drop. For wiring instructions, see
the diagram inside the pressure switch cover.
