Installation

LOcation

It is extremely important to install the compressor in a clean, well ventilated area where the surrounding air temperature will not be more than 100°F.

A minimum clearance of 18 inches between the compressor and a wall is required because objects could obstruct air flow.

Do not locate the

compressor air inlet near steam, paint spray, sandblast areas or any other source of contamination. This debris will damage the motor

Household use only. Store indoors.

Electrical installation

1.Check and tighten all bolts, fittings, etc., before operating compressor.

2.Operate compressor in a ventilated area so that compressor may be properly cooled.

3.Compressor should be located where it can be directly plugged into an outlet, but if this is not possible, an extension cord may be used. It should be selected using the extension cord chart on page 3 as a guide.

4.To avoid loss of power and overheating, it is better to use additional air hose instead of extension cords to reach work area.

Wiring

1.Local electrical wiring codes differ from area to area. Source wiring, plug and protector must be rated for at least the amperage and voltage indicated on motor nameplate, and meet all electrical codes for this minimum .

2.Use a slow blow fuse type T or a circuit breaker.

Overheating, short circuiting and fire

damage will result from inadequate wiring, etc.

All wiring and electrical

connections should be performed by a qualified electrician. Installation must be in accordance with local codes and national electrical codes.

NOTE: 120 volt, compressor can be operated on a 120 volt, 15 amp circuit under the following conditions:

a.No other electrical appliances or lights are connected to the same branch circuit.

b.Voltage supply is normal.

c.Extension cords are of the minimum gauge specified in this instruction manual.

d.Circuit is equipped with a 15 amp circuit breaker or a 15 amp slow blow fuse type T.

3.If above conditions cannot be met or if nuisance tripping of current protection device occurs, it may be necessary to operate compressor from a 120 volt, 20 amp circuit.

Grounding instructions

This product must be grounded. In the event of an electrical short circuit, grounding reduces the risk of electric shock by providing an escape wire for the electric current. This product is equipped with a cord having a grounding wire with an appropriate grounding plug. The plug must be

plugged into an outlet that is properly installed and grounded in accordance with all local codes and ordinances.

Figure 4 - Grounding Method

improper installation of the grounding

plug is able to result in a risk of electric shock. When repair or replacement of the cord or plug is required, do not connect the grounding wire to either flat blade terminal. The wire with insulation having an outer surface that is green with or without yellow stripes is the grounding wire.

Do not use adapter with this product!

Never connect

green (or green and yellow) wire to a live terminal.

Check with a qualified electrician or serviceman when the grounding instructions are not completely understood, or when in doubt as to whether the product is properly grounded. Do not modify the plug

provided; if it does not fit the outlet, have the proper outlet installed by a qualified technician.

This product is for use on a nominal 120V circuit and has a grounding plug similar to the plug illustrated in Figure 4. Only connect the product to an outlet having the same configuration as the plug. Do not use an adapter with this product.

Extension cords

To avoid loss of power and

overheating, it is better to use additional air hose instead of extension cords to reach work area.

Moisture in compressed air

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.

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 filter in the air line, located as near to the gun as possible, will help eliminate this moisture.

Use only a 3-wire extension cord that has a 3-blade grounding plug, and

a 3-slot receptacle that accepts the plug on the product. Make sure your extension cord is not damaged. When using an extension cord, be sure to use one heavy enough to carry the current your product draws. An undersized cord results in a drop in line voltage and loss of power and overheating. [The table on page 3 shows the correct size to use depending on cord length and nameplate ampere rating. When in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.]

Operation

Pressure Switch - ON/Off Switch (Figure 5) - In the ON 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.

 

Pressure

Switch

Figure 5 - ON/OFF Switch

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.

Exhaust Tube - This tube carries compressed air from the pump to the check valve. This tube becomes very hot during use. To avoid the risk of severe burns, never touch the exhaust tube.

Check Valve - A one-way valve that allows air to enter the tank, but prevents air in the tank from flowing back into the compressor pump.

Handle - Designed to move the compressor.

Drain Valve - This valve is located on the side of the tank. Use this valve to drain moisture from the tank daily to reduce the risk of corrosion.

Drain liquid from tank daily.

Reduce tank pressure below 10 psi, then drain moisture from tank daily to avoid tank corrosion. Drain moisture from tank by opening the drain valve located underneath or on the side of the tank.

Before first start-up Break-in procedure

(Complete this procedure before using compressor for the first time. Once completed, it is not necessary to repeat.)

1.Turn regulator knob fully clockwise (to the right) to open air flow and open drain valve.

2.Turn On/Off switch to OFF position.

Operation (Cont.)

5.Turn On/Off switch to OFF position.

6.Unplug power cord.

7.Close drain valve.

The compressor is now ready for use.

Before each start-up operating procedure

1.Turn regulator knob fully counter clockwise (to the left) to close air flow.

2.Connect air hose to outlet of regulator.

3.Turn On/Off Switch to OFF position.

4.Plug in power cord.

5.Turn On/Off Switch to ON position and let compressor run until it reaches automatic shutoff pressure.

6.Attach tire chuck or tool to end of hose.

7.Turn regulator knob clockwise (to the right) to desired pressure of tool being used.

On/Off cycling of compressor

In the ON position, the compressor pumps air into the tank. When a shut-off (preset “cut-out”) pressure is reached, the compressor automatically shuts off.

If the compressor is left in the ON position and 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 being used

continuously, the compressor will cycle on and off automatically.

In the OFF position, the pressure switch cannot function and the compressor will not operate. Make sure switch

is in OFF position when connecting or disconnecting power cord from electrical outlet.

ASME Safety Valve

Do not remove or attempt to adjust

the safety valve!

Check the safety valve by performing the following steps:

1.Plug the compressor in and run until shut off pressure is reached (see Operating Procedure).

2.Wearing safety glasses, pull the ring on the safety valve (see Figure 6) to release pressure from compressor

tank. Use your other hand to deflect fast-moving air from being directed toward your face.

Figure 6

3.The safety valve should automatically close when pressure in the tank has been released. If the safety valve does not allow air to be released when you pull on the ring, or if it does not close automatically, it MUST be replaced.

Safety valve must be replaced if it

cannot be actuated or it leaks air after ring is released.

pressure gaugeS

Gauge attached to regulator indicates air pressure going to hose (and any tool attached to end of hose).

Gauge attached to pressure switch indicates air pressure in tank.

Maintenance

Release all pressure and disconnect

power before making any repair.

1.Check compressor for any visible problems, especially check air filter to be sure it is clean.

2.Pull ring on safety valve and allow it to snap back to normal position (Figure 6).

Safety valve must be replaced if it

cannot be actuated or it leaks air after ring is released.

3.Daily with compressor shut off: Depressurize system prior to draining tank. Drain moisture from tanks by opening drain cocks on the side or underneath end of tank.

NOTE: Drain cup should be emptied regularly.

Figure 7

Do not remove drain plug with tank under pressure.

4.Turn power OFF and clean dust and dirt from motor, tank, air lines and pump cooling fins.

NOTE: The air filter in the filter housing on the side of the head must be checked and cleaned periodically, more often if used under very dusty conditions or when a great deal of fog from spraying is allowed to circulate near unit.

Important: Unit should be located as far from spraying area as hose will allow to prevent over-spray from clogging filter.

Drain Cup valve operation

1.To open, slowly turn drain knob counter-clockwise 2 to 4 turns until water or air begins to escape into the cup.

NOTE: Do not turn or force the knob more than 2 to 4 turns, taking care not to remove the knob.

2.To prevent overflow, monitor the cup at all times when draining.

3.When the cup is partially full or draining is complete (whichever happens first), shut off drain by turning knob clockwise.

4.Empty the cup, disposing of the water properly.

5.If water remains in tank, continue draining until the unit is empty.

Turn counterclockwise to
