Cleaning the Supply Line Filter and
Internal Pump Screen
Cleaning the lter and the pump screen requires breaking the suction
line. The suction line is the portion of the supply line from the tank to the
remote pump. If air leaks develop in the suction line, the heater will not
operate properly.
Follow all instructions, including “recharging the Suction Line,” (page 26)
to avoid creating an air leak.
Replacing the Supply Line Filter
1. Remove the old lter canister.
• Carefully unscrew and remove the lter canister. Dispose of prop-
erly.
2. Replace the lter canister.
• Attach a replacement lter canister, P/N 176535.
Cleaning the Internal Pump Screen
1. Check the Screen
• Disconnect the inlet oil line from the pump.
• Using a ashlight, look into the pump inlet.
a) If the portion of screen visible at the inlet appears to be
clogged, go to Step 2.
b) If the screen appears unclogged, reconnect the inlet line
making sure that the connection is tight. Do not remove
the pump cover. Go to the instructions for “Recharging the
Suction Line” (below).
2. Remove and Clean the Screen
• To access the screen, the pump cover must be removed.
• Remove the four bolts that hold the pump cover. (Be
careful, pump is full of oil).
• Remove the cover being careful not to lose or damage the
gasket.
• Remove the circular screen and clean with a solvent and
compressed air.
