5. Setup and Installation

Proper installation is crucial for the performance and longevity of your DG03 Pump. Ensure all safety precautions are followed.

1. Preparation:
   • Disconnect the power supply to the existing air compressor.
   • Completely drain any air pressure from the tank.
   • Remove the old compressor pump, noting the connections for the intake, exhaust, and mounting.
2. Mounting:
   • Position the DG03 Pump on the compressor tank's mounting plate.
   • Verify that the mounting hole dimensions (Front to Back: 6-1/2", Side to Side: 5-7/8") align with your compressor's mounting pattern.
   • Secure the pump using appropriate bolts and washers (not included).
3. Pulley Installation:
   • Attach the 10-inch pulley to the motor shaft. The pulley features dual set screws for a secure fit.
   • Ensure proper alignment between the pump pulley and the motor pulley to prevent belt wear.
   • Install the drive belt, ensuring it has the correct tension (refer to your compressor's original manual for tensioning guidelines).

4. Connecting Air Lines:
   • Connect the intake line to the 1/2" FNPT intake port.
   • Connect the exhaust line to the 3/8" FNPT exhaust port.
   • Ensure all connections are tight to prevent air leaks.
5. Lubrication:
   • Before first use, fill the pump with SAE 30 non-detergent oil or full synthetic 10W-30 oil.
   • Use the oil sight glass to monitor the oil level. Fill until the level is at the center of the sight glass.

6. Electrical Connection:
   • Ensure your motor is rated for 3HP and 220V, drawing at least 15 amps.
   • Reconnect the power supply to the air compressor system.

6. Operating Instructions

Once installed, the DG03 Pump operates as part of your air compressor system. Refer to your air compressor's main instruction manual for general operating procedures.

• Initial Start-up: After installation, run the compressor for a short period (e.g., 15-30 minutes) without load to allow the oil to circulate and components to seat.
• Monitoring: During operation, periodically check the oil sight glass to ensure proper lubrication. Listen for unusual noises or vibrations.
• Pressure Regulation: The pump will build pressure until the system's pressure switch activates, shutting off the motor. It will restart when pressure drops below a set threshold.

7. Maintenance

Regular maintenance ensures optimal performance and extends the life of your DG03 Pump.

• Oil Level Check: Check the oil level before each use or daily. Maintain the oil level at the center of the sight glass.
• Oil Change: Change the pump oil after the first 50 hours of operation, then every 3 months or 200 hours, whichever comes first. Use SAE 30 non-detergent oil or full synthetic 10W-30. The oil drain hole is located opposite the shaft for easy access.
• Air Filter Inspection/Replacement: Inspect the intake air filter monthly. Clean or replace it if it appears dirty or clogged. A clogged filter reduces pump efficiency and can cause overheating.
• Belt Tension: Periodically check the drive belt tension. Adjust if too loose or too tight according to your compressor's specifications.
• General Cleaning: Keep the pump exterior clean, especially the cooling fins, to ensure efficient heat dissipation.
