Place uniton a level surface. Remove oil fill plug (A) and
slowly add a compressor 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 -from the top at any time.)
When filling the crankcase, the oil flows very slowly into
the pump. If the oil is added too quickly, itwill overflow
and appear to be full. Crankcase oil capacity is
approximately 16 fluid ounces. Replace oil fill plug.
NOTE
Drain end refill the compressor pump crankcase
after the first 1O0hours of operation,
Extension Cords
Fig. 7
To avoid voltage drop and power lossto the motor, and to prevent overheating, use
extra air hose instead of an extension cord.
If an extension cord must be used:
• use only a 3-wire extension cord that has a 3-blade grounding plug and a 3-slot
receptacle that will accept the plug on the extension cord.
• make sure the extension cord is in good condition.
• the extension cord should be no longer than 50 feet.
• the minimum wire size is 12 gauge (AWG). (Wire size increases as gauge
number decreases. 10 AWG and 8 AWG may also be used. DO NOT USE 14
AWG or 16 AWG.)
Voltage and Circuit Protection
Refer to your Parfs Manual for voltage and circuitprotection requirements of your
compressor. Use onlya fuse or circuitbreakerthat is the same ratingas the branch
circuiton whichthe air compressorisoperated. If the compressor is connected to a
circuit protected by fuses, use only dual element time delay fuses.
Piping
I_ Plastic or PVC pipe is not designed for use with
compressed air. Regardless of its indicated pressure rating, plastic
pipe can burst from air pressure. Use only metal pipe for air
distribution lines.
If a pipe lineis necessary, use pipe that is the same size as the airtank outlet.
Piping that istoo small will restrict the flow of air. If piping is over 100 feet long, use
the next larger size. Bury underground lines below the frost lineend avoid pockets
where condensation can gather and freeze. Apply pressure before underground
lines are covered to make sure ell pipe joints are free of leaks.
Connect the piping to the 3/8" NPT air outlet opening at the end of the air tank.
