OPERATING INSTRUCTIONS (CONTINUED)
On/Off Cycling of Compressor
Risk of Bursting. Drain tank every day to prevent corrosion and possible injury due
to tank damage. Do not operate drain with more than 40 psi in tank or drain valve
may be damaged. Drain tank of moisture daily using the drain valve in the bottom of the tank.
Unit care and maintenance. Drain liquid from tank daily.
In the
AUTO
position, the compressor pumps air into
the tank. When a shut-off (preset “cut-out”) pressure is
reached, the compressor automatically shuts off.
If the compressor is left in the
AUTO
position and air
is depleted from the tank by use of a tire chuck, tool,
etc., the compressor will restart automatically at its
preset “cut-in” pressure. When a tool is being used
continuously, the compressor will cycle on and off
automatically.
In the
OFF
position, the compressor will not operate.
Drain Tank. Disconnect, tag, unplug and lock out power
source; release pressure. Drain moisture from tank by
opening drain valve underneath tank (See Figure 8).
MOISTURE IN COMPRESSED AIR
Moisture in compressed air will form into droplets as it comes from an air compressor pump.
When humidity is high or when a compressor is in continuous use for an extended period of
time, this moisture will collect in the tank. When using a paint spray or sandblast gun, this
water will be carried from the tank through the hose, and out of the gun as droplets mixed
with the spray material.
IMPORTANT:
This condensation will cause water spots in a paint job, especially when
spraying other than water based paints. If sandblasting, it will cause the sand to cake and
clog the gun, rendering it ineffective. A filter in the air line, located as near to the gun as
possible, will help eliminate this moisture.
