5.1.2.3: Checking and cleaning the Heat Exchanger and back up Pump
The heat exchanger should be checked for weeds, leaves, debris or any other obstructions
around the sides of the unit and the heat rejection coils and fins. The coils and fins can be
cleaned with compressed air or a commercial coil cleaner, being careful not to distort the
fins. During the winter months, be sure to remove any snow accumulation around the
sides and top of the system or on the fan blades. Also check for leaks or excessive
vibrations in the plumbing and fan. If your system has a back up pump for your cooling
system, it will need to be cycled on approximately every 3 months to prevent it from
seizing up.
