2. Set manual disconnect switch to the ON position.

3. Fill the suction line (line between the supply tank and the pump) with

clean used oil. (Do not use new motor oil.)

4. Locate the rubber tubing connecting the pressure switch in the main

control box and the compressor.

• Disconnect the tubing at the fitting on the compressor. This will prevent

oil from flowing to the burner.

5. Remove the cad-cell wire from the F1-F2 terminals of the ignition

controller.

• Either attach a piece of tubing to the bleeder valve on the strainer tee

(see page 26) on the burner assembly or place a container underneath

to collect oil.

• Loosen the bleeder valve.

6. Set the thermostat to a temperature above room temperature.

NOTE: On initial start-up it will take approximately ten minutes to heat

the oil. Once the oil is warm enough, the green light will come on and the

unit will be ready to start. This delay only occurs on initial start-up or when

the disconnect switch has been turned off for an extended time.

• After the motor starts, place a jumper across the cad-cell terminals

(F1-F2) on the ignition controller.

• Observe the remote fuel pump motor to make certain it is running.

• Open the bleeder valve on the remote pump and wait until a full flow

of oil is obtained without any air.

IMPORTANT NOTE: If air bubbles are present and do not stop, there is a

suction line leak.

• Check the piping between the tank and the pump and correct the leak.

• Once a full flow of oil is present without any sign of air, close the

bleeder valve on the remote pump.

• Observe the bleeder valve at the strainer tee and wait until a full flow

of oil is obtained without any air.

• Tighten the bleeder valve on the strainer tee and remove the oil con-

tainer.

NOTE: DO NOT replace the rubber tubing previously disconnected from

the compressor and DO NOT re-connect the cad-cell wires.

7. Allow the system to operate for several minutes.

• Check the system for leaks at all connections.

• Observe the return line to the tank - oil should be flowing.

• Correct all leaks and re-test the system.

8. When the system checks out as having no leaks, turn disconnect

OFF, replace the rubber tubing and cad-cell wires removed earlier.

9. Remove the jumper from the F1-F2 terminals of the ignition

controller.
