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
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 Johnson Controls
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
frame. Canvas or flexible connectors should also be used
to minimize vibration between the unit and ductwork.
