INSTALLATION

Please read and follow the installation instructions carefully to avoid injury or damage to the compressor and your vehicle. Each of our air compressors and parts have been carefully produced and packaged. Before you begin installation, please familiarize yourself with Installation Parts List (Fig.

1. of this manual.

Guidelines for Selecting Mounting Location:
The selection of proper mounting location for your air compressor will help ensure a long and trouble free compressor service life. Please pay close attention to the following guidelines:

1. Select a FLAT, UPRIGHT AND SECURE location where the compressor can be mounted.
2. To maximize air compressor performance, locate compressor as CLOSE TO THE BATTERY as possible so that length of positive lead wire required is at a minimum.
3. Choose mounting location that is as cool as possible and AWAY FROM HEAT SOURCES. The cooler the ambient temperature, the less chance the compressor will overheat.
4. This compressor is moisture & dust resistant, but NOT DIRT OR WATERPROOF. Do not mount compressor in locations where the unit is likely to come in contact with the elements.
5. If it is necessary to mount the air compressor further away from the battery, such as inside your vehicle or in the bed of your pickup, use a positive lead wire for remote installation. Refer to the wire gauge guide on the back of this manual.
6. Do not mount compressor near areas where flammable liquids are stored.
7. Use thread sealant for proper fitting installation. Thread tape is not recommended. Properly sealed, recommended torque is 12 to 15ft. lbs.

MOUNTING AND WIRING

1. Disconnect ground cable from vehicle’s battery.
2. Temporarily position the air compressor in the location where it will be mounted.
3. Route ground wire to the negative post of the battery or to an appropriate grounding point and cut ground wire to length as needed.
4. Mount the air compressor with the four sets of 13/64″ (5 mm) bolts, nuts, washers, and locking washers provided. (See Fig. 2 for Mounting Instructions) Use of thread sealant is recommended.
5. Your air compressor comes with a heavy duty heat-resistant leader hose with 3/8″ fittings. This leader hose is designed to prolong the life of your air line. Do not remove the leader hose from the air compressor.
6. IMPORTANT: Please note, the leader hose that came with your compressor may have a built-in inline check valve. Do not remove inline check valve from leader hose.
7. Connect compressor positive lead wire to one of the leads of your pressure switch (sold separately).
8. Make sure that your compressor setup is properly fused. The compressor will pull no more than 23-Amps peak.
9. Always locate fuse as close as possible to power source.
10. Before connecting to power source, re-check to make sure that all connections are made properly.
11. Connect and test compressor system by running the compressor for a short time to build up pressure in your air tank.
12. Once air pressure reaches preset cut out pressure of your pressure switch, the compressor will shut off. Inspect all air line connections for leaks with soap and water solution. If a leak is detected, the air line may not be cut squarely or pushed all the way in.
    Repair connections as needed.

OPERATING INSTRUCTIONS

1. IMPORTANT: Always operate the compressor at or below the MAXIMUM PRESSURE RATING of the compressor (200 PSI).
2. Always observe the MAXIMUM DUTY CYCLE of the air compressor. Refer to Compressor Applications and Specifications Sections of this manual for details. Operation exceeding maximum pressure ratings and/or duty cycle will result in damage to the air compressor.
3. Your air compressors are equipped with AUTOMATIC THERMAL OVERLOAD PROTECTORS. This feature is designed to protect the air compressor from overheating and causing permanent damage. The thermal overload protector will automatically cut power to your air compressor should the internal operating temperature of the air compressor rise above safe levels during excessive use.
4. Should at any time during use, your air compressor automatically shut off, do not attempt to restart them. Cut power to the air compressor. The automatic thermal overload protector will automatically reset when internal temperature of the air compressor drops below safe levels. After allowing air compressor to cool off for about 30 minutes, you can safely resume use of the air compressor.
5. To prevent discharge of your vehicle’s battery, we recommend that you keep the vehicle’s engine running while operating air compressors.
6. ONLY OPERATE AIR COMPRESSORS IN WELL-VENTILATED AREAS.
7. Compressor performance is enhanced when operating compressor with vehicle’s engine running.

MAINTENANCE & REPAIRS

1. Periodically check all electrical, fittings connections. Clean and tighten as needed.
2. Periodically check all mounting screws. Tighten as needed.
3. Replace Air Filter Element periodically. Replacement frequency depends on operating frequency and operating environment. For frequent use in dusty environments, we recommend that you replace air filter element once a month.
4. Regularly clean dust and dirt from compressor cooling fins and motor housing.
5. Your air compressor is equipped with a permanently lubricated, maintenance-free motor. Never try to lubricate the compressor.
6. All repairs should be performed by Manufacturer or Manufacturer’s Authorized Service Agencies only.

CAUTION: Never touch the air compressor or fittings connected to the air compressor with bare hands during or immediately after use. The leader hose and fittings connected to leader hose will become very HOT during and after use. If necessary, wear heat resistant gloves to handle fittings, air line, and leader hose.

COMPRESSOR APPLICATION GUIDE

To ensure that you get the highest level of satisfaction from your compressor’s performance, refer to information below:

VIAIR® COMPRESSOR REFERENCE CHART

ABOUT COMPRESSOR DUTY CYCLE:
Duty cycle refers to the amount of time a compressor can be operated in a given time period at 100 PSI, and a standard ambient temperature of 72° F. It is commonly expressed in percentage format: Compressor on time ÷ (on time + off time) = Duty Cycle%.

NOTE: All compressors, regardless of rated duty cycle, require sufficient rest time in between cycles to allow for partial or complete heat dissipation. Heat dissipation rates may vary depending on ambient temperatures and operating conditions.

ABOUT RATED WORKING PRESSURE:
To ensure trouble free service life of your compressor, always operate compressor within rated working pressure of the compressor. Never use a pressure switch with a higher cut-off pressure than compressor’s rated working pressure.
