ing equipment.
Turn off the system and ensure power and gas supply is shut off before
servicing equipment.
Read this manual carefully before installation, operation, or service of
this equipment.
System Tubing and Vent
Pipe
Venting must be intact. Using a flashlight, look for obstructions, cracks on the
pipe, gaps in the sealed areas or corrosion.
The area must be free of dirt and dust or blockage.
Remove any carbon deposits or scale using a wire brush.
Replace pipe if there are any holes due to corrosion. Seal any gaps in venting
to prevent condensate leakage.

Compressed air or a vacuum cleaner may be used to clean dust and dirt.
Check for corrosion, if any parts have corroded through, replace as neces-
sary.
Ensure all hex nuts are tight for proper seal.
Suspension Points Make sure the pump is hanging securely.
Look for signs of wear on the mounting angles, wall mounting points or ceiling
mounting points.
Pump Boot Inspect pump boot at pump inlet and outlet for cracking or deterioration.
Replace if cracks are found.
Ensure band clamps are tight at all connection points.
Condensate Trap, Drain
Cap
Check connection of tee to drain cap and between tee and condensate trap.
Seal connections between tee and drain cap to prevent condensate leakage.
Screw condensate trap tightly into drain cap or pump inlet assembly to pre-
vent leakage.
Condensate trap should be filled with water.
