Air Coil
To obtain maximum performance, the air coil should be cleaned
before start-up. A 10% solution of dishwasher detergent and
water is recommended for both sides of the coil. A thorough
water rinse should follow. UV based anti-bacterial systems
may damage e-coated air coils.
NOTICE! Installation Note - Ducted Return: Many horizontal
WSHPs are installed in a return air ceiling plenum application
(above ceiling). Vertical WSHPs are commonly installed in a
mechanical room with free return (e.g. louvered door). Therefore,
filter rails are the industry standard and are included on Heat
Controller, Inc., commercial heat pumps for the purposes of
holding the filter only. For ducted return applications, the filter rail
must be removed and replaced with a duct flange or filter rack.
Canvas or flexible connectors should also be used to minimize
vibration between the unit and ductwork.
