2. Safety Information

Always observe the following safety precautions to prevent injury or damage to the equipment:

• Electrical Safety: Ensure the compressor is connected to a properly grounded electrical supply matching the specified voltage (208-230V or 460V). Disconnect power before performing any maintenance or service.
• Pressure Safety: Never exceed the maximum operating pressure of 175 PSI. Do not tamper with the safety relief valve.
• Moving Parts: Keep hands, hair, and clothing clear of moving parts such as belts and pulleys. The belt guard must always be in place during operation.
• Hot Surfaces: The compressor pump and discharge lines can become very hot during operation. Avoid contact to prevent burns.
• Ventilation: Operate the compressor in a well-ventilated area to prevent the accumulation of carbon monoxide and to ensure proper cooling.
• Drainage: Regularly drain condensate from the air tank to prevent corrosion and maintain air quality.
• Personal Protective Equipment (PPE): Wear appropriate safety glasses or goggles, hearing protection, and other necessary PPE when operating or servicing the compressor.

3. Setup and Installation

3.1 Unpacking and Inspection

Carefully remove the compressor from its packaging. Inspect for any shipping damage. Report any damage to your supplier immediately.

3.2 Location Requirements

Place the compressor on a firm, level surface capable of supporting its weight (approximately 938 lbs). Ensure adequate clearance around the unit for ventilation and maintenance access. The operating environment should be clean, dry, and well-ventilated. This unit is designed for outside usage.

3.3 Electrical Connection

This compressor requires a 208-230V or 460V, 3-phase electrical supply. Consult a qualified electrician for proper wiring and connection to ensure compliance with local electrical codes. The unit features magnetic starters mounted and wired for TEFC motors on 10/15/20HP models.

3.4 Initial Checks

4. Operating Instructions

4.1 Starting the Compressor

1. Ensure all connections are secure and the power supply is connected.
2. Open the air outlet valve slightly to allow the compressor to start without full load.
3. Turn on the main power switch. The compressor will start automatically and build pressure.
4. Once the desired pressure is reached, the compressor will shut off automatically due to the auto start/stop pressure switch operation.

4.2 Adjusting Pressure

The operating pressure can be adjusted using the pressure regulator, typically located near the pressure gauge. Turn clockwise to increase pressure and counter-clockwise to decrease pressure. Monitor the pressure gauge during adjustment.

4.3 Shutting Down

1. Turn off the main power switch.
2. Close the air outlet valve.
3. Bleed any remaining air pressure from the tank using the manual condensate drain or an air tool connected to the outlet.

5. Maintenance

Regular maintenance is crucial for the longevity and efficient operation of your air compressor.

5.1 Daily Maintenance

• Drain Condensate: Open the manual condensate drain valve at the bottom of the tank to release accumulated moisture. Close the valve once all water has been expelled.
• Check Oil Level: Verify the oil level in the compressor pump.

5.2 Weekly Maintenance

• Inspect Air Filter: Check the air filter for dirt and debris. Clean or replace if necessary.
• Inspect Belts: Examine drive belts for wear, cracks, or proper tension. Adjust belt tension as needed; easy access is provided for this adjustment.

5.3 Monthly/Quarterly Maintenance

• Change Oil: Replace the compressor oil according to the manufacturer's recommendations or every 300 operating hours, whichever comes first.
• Inspect Safety Valve: Briefly pull the ring on the safety relief valve to ensure it operates freely.
• Check for Leaks: Listen for air leaks around fittings and connections. Tighten as needed.
