4. Locate the rubber tubing connecting the pressure switch in the
main control box and the compressor.
• Disconnect the tubing at the tting on the compressor. This will
prevent oil from owing 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 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
ow 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 ow 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
ow of oil is obtained without any air.
• Tighten the bleeder valve on the strainer tee and remove the oil
container.
NOTE: DO NOT replace the rubber tubing previously disconnected from
the compressor and DO NOT reconnect 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 owing.
• Correct all leaks and retest 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.
