4. Setup and Installation
Proper installation is crucial for the safe and efficient operation of the Suntec A2RA-7710 pump. Refer to your specific Reznor Waste Oil Heater manual for detailed instructions on pump replacement.
Installation Steps:
- Power Disconnection: Ensure the main power supply to the waste oil heater is completely disconnected and locked out.
- Drain Oil: If necessary, drain any oil from the existing pump and associated lines to prevent spills.
- Remove Old Pump: Carefully disconnect all oil lines and electrical connections from the old pump. Unbolt and remove the old pump from its mounting flange.
- Inspect Mounting Area: Clean the mounting surface on the heater to ensure a flush fit for the new pump.
- Install New Pump: Mount the Suntec A2RA-7710 pump onto the heater's mounting flange, ensuring the shaft aligns correctly with the motor coupling. Secure with appropriate bolts.
- Connect Oil Lines: Reconnect the inlet and outlet oil lines to the corresponding ports on the new pump. Ensure all connections are tight to prevent leaks. Use thread sealant if recommended by the heater manufacturer.
- Electrical Connections: Reconnect electrical wiring according to the heater's wiring diagram. Double-check all connections for security and correct polarity.
- Prime the Pump: Before restoring power, it is essential to prime the pump to remove any air from the oil lines. Consult your heater's manual for the specific priming procedure. This typically involves opening a bleed valve and allowing oil to flow until air bubbles cease.
- Leak Check: After priming, visually inspect all connections for any signs of oil leaks.

5. Operation
Once installed and primed, the Suntec A2RA-7710 pump operates in conjunction with the waste oil heater's control system. The pump's primary function is to draw waste oil from the supply tank and deliver it under pressure to the burner nozzle.
Initial Startup:
- Ensure all installation steps, especially priming, have been completed.
- Restore power to the waste oil heater system.
- Initiate the heater's startup sequence as per its manufacturer's instructions. The pump should begin to operate, delivering oil to the burner.
- Monitor the system for proper oil flow and pressure. Adjust the pump's pressure regulator if necessary, referring to the heater's specifications for recommended pressure settings.
Note: The pump's pressure regulator is factory-set but may require fine-tuning during initial startup or after significant system changes. Adjustments should only be made by a qualified technician.
