Operation (continued)
ON/OFF CYCLING OF THE COMPRESSOR
The air compressor unit (A) is designed to cycle on and off. When the shut-off (preset “cut-out”) pressure is reached, the compressor
automatically shuts off.
When 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 in use, the compressor will cycle on and off automatically as needed to maintain air pressure in the tank.
MAGNETIC STARTER
CAUTION:
Repeated overloads can cause damage to the
motor and void the product warranty.
The magnetic starter is a large relay that switches high current from the main power line in response to a signal from the pressure switch.
The starter also has a device to protect the electric motor against overheating due to overcurrent. This protection is accomplished by heater
elements that become hot in response to the motor current. The heaters are sized so that overcurrent causes them to interrupt power to the
section of the starter controlling motor current, turning the motor off. After the heater elements cool, reset the starter to resume operation.
In normal operation, the starter requires no attention. If an overload occurs, follow the thermal overload reset instructions in the
Maintenance section of this manual.
MOISTURE IN COMPRESSED AIR
WARNING:
Drain the tank every day to prevent corrosion
and possible injury due to tank damage. For optimal
performance of the tank drain, the tank pressure should be
between 10 - 50 psi. Do not operate the drain with more than
40 psi in the tank or the drain valve may be damaged. Drain
the tank of moisture daily using the drain valve in the side of
the tank or at the bottom of the tank.
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 fi lter in the air line,
located as near to the gun as possible, will help eliminate this
moisture.
IMPORTANT:
Drain liquid from the tank daily.
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.
Follow the tank draining instructions in the Maintenance section of this manual.
