OPERATING INSTRUCTIONS (CONTINUED)
Recommended Break-In Period
The compressor should be run continuously for one hour to allow proper seating of the piston rings.
1. Open drain cock completely and run the compressor for 60 minutes.
2. Turn off the compressor and close drain cock. The compressor is now ready for use.
Pressure Switch, Start - Stop
NOTE: This compressor has a maximum operating
pressure of 175 psi. Do not alter pressure settings on
control components above this limit.
The compressor unit starts and stops based on preset
pressure switch settings of 145 psi cut-in and 175 psi
cut-out. The pressure switch contains an unloader
which is a small valve that vents air to allow the motor
to start easily (see Figure 11).
The unloader valve on the pressure switch should hiss
for a short period of time when the compressor shuts
off. This relieves the head and the exhaust tubing of
any pressure and allows the compressor to start under
no load. Because compressors have high starting
torque the unloader is necessary for proper starting of
the compressor.
The check valve is a one way valve that keeps the air
in the tank when the unit shuts off. The easiest way to determine if the check valve is working properly is to make
sure that the pressure switch unloader quits hissing after the compressor shuts off. The hissing should last for
several seconds and then quit.
Crankcase Breather
During severe operating conditions or initial start-up, some oil may accumulate at the crankcase breather
opening. This is normal and will diminish as the pump accumulates run time and the piston rings become fully
seated.
Draining Tank
Condensate must be drained from the tank daily,
use manual tank drain (see Figure 12). Refer to
instructions provided with the automatic drain.
