INSTALLATION HOW TO SET UP YOUR UNIT Location of the Air Compressor • Locate the air compressor in a clean, dry, and well ventilated area. Locate the air compressor at least 12" away from the wall or other obstructions that will interfere with the flow of air. Locate the air compressor as close to the main power supply as possible to avoid using long lengths of electrical wiring. NOTE: Long lengths of electrical wiring could cause power loss to the motor. The air filter must be kept clea

Wiring Instructions RISK OF ELECTRICAL SHOCK. Improper electrical grounding can result in electrical shock. The wiring should be done by a qualified electrician to comply with national and local electrical codes. A qualified electrician needs to knows the following before wiring: 1. The amperage rating of the electrical box should be adequate. Refer to the product specifications, found in the front of this manual, for this information. 2. The supply line should have the same electrical characte

Use pipe that is the same size as the air tank outlet. Piping that is too small will restrict the flow of air. If piping is over 100 feet long, use the next larger size. Bury underground lines below the frost line and avoid pockets where condensation can gather and freeze. Apply pressure before underground lines are covered to make sure all pipe joints are free of leaks. A flexible coupling is recommended to be installed between the air discharge outlet and main air distribution line t

2. Recheck all wiring. Make sure wires are secure at all terminals connections. Make sure all contacts move freely and are not obstructed. 3. Open the globe valve fully to permit air to escape and prevent air pressure build up in the air tank during the break-in period. 4. Move the On/Auto/Off lever to "ON/AUTO" position. The compressor will start. 5. Run the compressor for 20 minutes. Make sure the globe valve is open and there is minimal air pressure build-up in tank. 6. Check all air line fit

Air Filter - Inspection and Replacement Hot surfaces. Risk of burn. Compressor heads are exposed when filter cover is removed. Allow compressor to cool prior to servicing. Keep the air filter clean at all times. Do not operate the air compressor with the air filter removed. A dirty air filter will not allow the compressor pump to operate at full capacity. Before using the compressor pump, check the air filter to make sure it is clean and in place. If it is dirty, replace it with a new filter.
