AIr CoMPressor PuMP
The pump compresses air into the air tank. Working air is not
available until the compressor has raised the air tank pressure
above that required at the air outlet.
AIr IntAke fIlter
The filter (J) is designed to clean air entering the
pump. To ensure the pump continually receives a
clean, cool, and dry air supply the filter must always
be clean and the filter intake must be free from
obstructions.
Motor oVerloAD ProteCtor
The motor has a thermal overload protector. If
the motor overheats
for any reason, the overload protector will shut
off the motor. The
motor must be allowed to cool down before
restarting. To restart:
1. Set the Auto/Off switch to OFF(O) and
unplug unit.
2. Allow the motor to cool.
3. Depress the red reset button (R) on the motor.
4. Plug the power cord into the correct branch circuit receptacle.
5. Set the Auto/Off switch to AUTO(–) position.
DuAl Control
Dual control allows the compressor to operate in the
constant run or the stop/start mode of operation. The
pilot valve (M) is used to control the compressor when
operating in the constant run mode. The pressure
switch is used to control the compressor when
operating in the stop/start mode. The mode of
operation is determined by the amount of time the compressor will be
required to supply air. If the demand for air is infrequent, then the unit
should be operated in the stop/start mode to minimize unnecessary
run time and to save energy. If there is a frequent or extended demand
for air, and/or the unit is located in a remote area where access to the
compressor is difficult, the unit should be operated in the constant run
mode to minimize the number of times the motor must start in an hour
to ensure good motor life.
DuAl VoltAGe
J
The dual voltage (N) feature allows the
compressor to operate in 115 or 230 volt
operation. The advantage of running in the 230
volt operation is a lower current draw. Lower
R
current draw may be necessary in areas with a
poor power source. Lower current also reduces
operating costs. See 230 Volt Conversion
under Installation.
PIlot VAlVe
When the maximum air tank pressure is obtained, the pilot valve
(M) will blow-off.
INSTALLATION
Assembly (Fig. 1)
InstAllInG Hoses
WARNING: Risk of unsafe operation. Firmly grasp hose in hand
M
when installing or disconnecting to prevent hose whip.
1. Ensure regulated pressure gauge reads 0 psi.
2. Grasp the hose at the quick connect plug and push the plug
into the quick connect body (E). Coupler will snap into place.
3. Grasp the hose and pull to ensure coupler is seated.
