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 will 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 HC
Series 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.
