CLIMATEMASTER WATER-SOURCE HEAT PUMPS
Horizontal Installation, Cont’d.
Figure 3: Typical Horizontal Unit Installation
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, lter rails are the industry
standard and are included on ClimateMaster commercial
heat pumps for the purposes of holding the lter only. For
ducted return applications, the lter rail must be removed
and replaced with a duct ange or lter frame. Canvas
or exible connectors should also be used to minimize
vibration between the unit and ductwork.
