EXCHANGER COIL MAINTENANCE
A clean coil is crucial to the efficiency of the unit. If necessary, clean the coil with a
vacuum cleaner.
If the coil must be disassembled on account of a leak:
●
Disconnect the water coil and the condensate drain.
●
Remove the fan motor assembly (see the information above)
●
Remove the condensate drain pan (see the information above)
●
Unscrew the side screws from the exchange coil and remove it from its housing
between the unit's support feet.
Note: The condensate pan can be removed without having to remove the coil.
CASING MAINTENANCE
To maintain the appearance of the unit, wipe it clean with a slightly soapy, damp sponge and
buff it with a soft, dry cloth. Use water-based non-abrasive cleaners.
