For Carlin EZ-Temp aquastats, refer to the pre-packaged installation guide for proper set-up procedure. Refer to drawings for correct models. Connect the power supply to the aquastat and run through a fused disconnect switch (attached to heater in field). See Figure 1. Gravity System: The oil burner is normally equipped with a single-stage pump equipped for one line (gravity) flow. Use 1/2" O.D. soft copper tubing and attach with flared fittings. DO NOT USE COMPRESSION FITTINGS. Install the shut off valve and oil filter in the oil line. Follow the pump manufacturer’s instructions (attached to the pump). Lift System: The burner should be ordered with a 2-stage pump. Run a 2-line system (suction and return lines). Install the bypass plug according to the instructions attached to pump (plug is in a bag with an instruction sheet). – 5 – PLACE THE WATER SYSTEM IN OPERATION Warning: Handhole cover may loosen during shipping – check for tightness before putting heater in operation. – 5 – PLACE THE WATER SYSTEM IN OPERATION Warning: Handhole cover may loosen during shipping – check for tightness before putting heater in operation. For any horizontal run exceeding the maximum length specified in Figure 4, or any lift of more than 10 feet, a booster pump must be used. Booster pumps may be obtained from Sun Tec Hydraulics, Rockford, Illinois. Booster pumps must be installed as close to the oil supply tank as possible. Suction and return lines should be the same diameter and both go within 6” of the bottom of the tank. The return line should stop slightly above the suction line. Use a minimum of fittings. Make bends in the tubing with as large a radius as possible. DO NOT USE COMPRESSION FITTINGS. Caution must be used in the final connection to the burner so as not to strain the fuel unit. Before attaching the tubing to the burner, form a coil in the tubing to minimize any vibration. Bury the oil lines in the floor for quiet operation, making sure there are NO CONNECTIONS OR FITTINGS UNDER THE FLOOR.

Fill the tank with water, opening a hot water faucet to allow trapped air to escape from the heater. Open the cold water inlet valve. Shut off each faucet as it delivers water that is free of air. Inspect for leaks. Never operate an empty or partially full heater. 2. Be sure the oil tank is filled with #1 or #2 heating oil. Remove the transformer hold down screw and swing the transformer back open on the hinge. Rotate the blower wheel a few times to loosen the pump shaft. Swing the transformer closed and fasten. 3.
