Speedaire Operating Instructions and Parts Manual
Model 5Z598C
Installation (Continued)
1.Air compressor is equipped with a cord having a ground wire with an appropriate grounding plug. Plug must be used with an outlet that has been installed and grounded in accordance with all local codes and ordinances. Outlet and plug must have the same configuration. DO NOT USE AN ADAPTER.
2.Do not modify the provided plug. If it does not fit the available outlet, the correct outlet should be installed by a qualified electrician.
3.Inspect plug and cord before each use. Do not use if there are signs of damage.
Risk of electrical shock. If repairing
or replacing cord or plug, the grounding wire must be kept separate from the

BREAK-IN PROCEDURES
This procedure is only required the first time the air compressor is put into service and when the check valve has to be replaced.
1.Set the pressure switch OFF/AUTO lever to the OFF position.
2.Plug power cord into the correct branch circuit receptacle.
3.Turn regulator clockwise, opening it fully, to prevent air pressure build- up in the tank.
4.Move the OFF/AUTO lever to AUTO. Compressor will start.
5.Run the compressor for 15 minutes. Make sure the regulator is open and there is no tank pressure buildup.
6.After 15 minutes, close the regulator by turning it counter- clockwise. Air tank will fill to
Operation
AIR COMPRESSOR PUMP
To compress air, the piston moves up and down in the cylinder. Air is drawn in through the air intake valves on the downstroke of the piston. Exhaust valve remains closed. On the upstoke of the piston, air is forced out through the exhaust valve, through the outlet tube, through the check valve and into the air tank. Working air is not available until the compressor has raised the air tank pressure above what is required at the air outlet.
CHECK VALVE
When the air compressor is operating, the check valve is "open", allowing compressed air to enter the air tank. When the air compressor reaches "cut- out" pressure, the check valve closes, allowing air pressure to remain inside the air tank.
UNLOADER VALVE
The unloader valve located on the side of the pressure switch, is designed to automatically release compressed air from the compressor head and the outlet tube when the air compressor reaches

SAFETY VALVE |
|
|
| ||
|
|
| |||
If the pressure switch does not shut off |
| ||||
the air compressor at its |
| ||||
pressure setting, the safety valve will |
| ||||
protect against high pressure by |
| ||||
"popping off" at its preset pressure. |
| ||||
REGULATOR |
|
|
|
| |
Air pressure coming from the air tank |
| ||||
is controlled by the regulator knob. |
| ||||
Turn the knob clockwise to increase |
| ||||
pressure and |
| ||||
decrease pressure. To avoid minor |
| ||||
readjustments after making a change |
| ||||
in pressure setting, always approach |
| ||||
the desired pressure from a lower |
| ||||
pressure. When reducing from a higher |
| ||||
to a lower setting, reduce to a pressure |
| ||||
lower than what is desired, then raise |
| ||||
the pressure to the desired setting. The |
| ||||
outlet regulated air pressure may need |
| ||||
to be adjusted while operating, |
| ||||
depending on the air requirements of |
| ||||
the accessory. |
