Introduction
This pool/spa heat pump is an electromechanical machine that incorporates
a pressurized refrigerant gas in a sealed system. ONLY trained and qualified
service personnel should attempt to install or service this equipment.
Without proper training and knowledge of such equipment, any attempt to
install or service the unit could result in serious injury or even death.
This manual contains important information on the use, maintenance, chemistry requirements and
installation of your new heat pump. Proper installation and operation of the unit will increase the
benefits you receive from the unit.
This heat pump is an extremely efficient, economical machine designed specifically for pool and
spa heating. It is similar in design and operation to a typical residential air conditioning system.
The heat pump employs a hermetic motor/compressor operating in a refrigeration cycle to extract
heat from ambient air and deliver it to the circulating pool water.
As with all pool/spa heat pumps, compared to other types of pool heat pumps such as gas- or oil-
fired, this heat pump has lower heating capacity on a BTU/hr basis. As a result, it will be required
to operate longer to accomplish the desired results. It may, at certain times, operate as much as 24
hours per day. However, this should not be of concern to the owner, because the unit is designed
to operate continuously. Even though it may operate continuously for many hours, it will still heat
the pool with greater economy than other types of fossil fuel heaters.
You are advised to put a pool cover over the pool at night and other non-use periods. This will
keep evaporation, the cause of the greatest heat loss, to a minimum, and so greatly reduce overall
pool heating costs. During warmer weather, the pool cover may be required only at night.
I. Installation
• The placement of the pool heat pump is very important to minimize installation costs while
providing maximum efficiency of operation, and to allow adequate service access.
• The unit is designed for outdoor installation and must not be installed in a totally enclosed
area such as a shed or garage, unless ventilation is provided to ensure adequate air exchange
for proper operation. Recirculation of cold discharge air back into the evaporator coil will
greatly reduce the unit’s heating capacity and efficiency.
• When installed in a geographical location where freezing temperatures can be encountered,
the water circuit should be drained to prevent possible freeze-up damage. See Section IX,
Freeze Protection.
• The unit should be located as close as possible to the existing pool pump and filter to
minimize water piping.
• All models feature an "up-flow" discharge for quiet operation. Air is pulled up through the
evaporator coil and discharged through the top grill. Allow at least 8 ft clearance above the
unit for unrestricted air discharge. Do NOT install the unit under a porch or deck.
