equipment . .Follow .all .instructions .
• . Only .persons .well .acquainted .with .
these .rules .of .safe .operation .should .
be .allowed .to .use .the .unit .
Components
Pressure switch .- .Auto/Off .Switch .- .In .
the ."AUTO" .position, .the .compressor .
shuts .off .automatically .when .tank .
pressure .reaches .the .maximum .preset .
pressure . .In .the ."OFF" .position, .the .
compressor .will .not .operate . .This .switch .
should .be .in .the ."OFF" .position .when .
connecting .or .disconnecting .the .power .
cord .from .the .electrical .outlet .or .when .
changing .air .tools .
regulator .- .The .regulator .controls .the .
amount .of .air .pressure .released .at .the .
hose .outlet .
ASME Safety valve .- .This .valve .
automatically .releases .air .if .the .tank .
pressure .exceeds .the .preset .maximum .
Pressure Gauges .- .The .gauge .attached .
to .pressure .switch .will .show .air .
pressure .in .tank . .The .gauge .attached .to .
regulator . .will .show .air .pressure .at .the .
hose .outlet .
removal of Existing Switch
1 . . . Disconnect .power .and .release .all .air .
pressure .from .tank .
2 . . . Remove .existing .pressure .switch .
cover .screw(s), .then .remove .cover .
3 . . . Locate .cut-outs .on .the .back .of .
pressure .switch .(See .Figure .3) . .Insert .
tip .of .small .screwdriver .into .cutouts, .
then .push .to .release .wires .
4 . . . Remove .ground .screw .(See .Figure .3) .
5 . . . Remove .strain .relief .screw .(See .
Figure .3) .
6 . . . Pull .unloader .tube .off .existing .
pressure .switch . .Remove .screw .
holding .pressure .switch .to .pressure .
switch .assembly . .Then .remove .switch .
from .unit .
7 . . . Disconnect .unloader .tube .from .
check .valve .
8 . . . Remove .the .remainder .of .pressure .
switch .assembly .by .unscrewing .tank .
fitting .
New Switch Installation
New switch must
have same maximum
pressure as existing switch. Pressure
rating is listed on the bottom of
assembly.
1 . . . Screw .pressure .switch .assembly .onto .
tank .
2 . . . Replace .existing .unloader .tube .
connection .at .check .valve .with .new .
quick .connect .supplied .in .kit .
3 . . . Insert .new .unloader .tube .into .quick .
connect .fitting .on .check .valve .
4 . . . Insert .other .end .of .unloader .tube .
into .unloader .valve .on .pressure .
switch . .Unloader .tube .can .be .cut .if .
supplied .length .is .too .long .
5 . . . Loosen .pressure .switch .cover .screw, .
then .remove .cover .
6 . . . Two .strain .relief .clamps .will .be .
provided .in .the .kit . .Determine .which .
strain .relief .clamp .to .use .based .on .
the .diameter .of .the .line .cord .
7 . . . Loosely .attach .strain .relief .clamp .to .
pressure .switch .with .screw .provided .
in .kit . .Insert .motor .and .line .cord .into .
switch . .Tighten .strain .relief .clamp .
screw .to .hold .cords .securely .
8 . . . Position .black .motor .wire .
underneath .screw .head .#4 .(See .
Figure .4), .then .tighten .screw .to .
secure .wire . .Position .black .line .wire .
underneath .screw .head .#2, .then .
tighten .screw .to .secure .wire .
9 . . . Position .white .line .wire .underneath . .
screw .head .#1, .then .tighten .screw .
