Heat Pump Overview

Your Pentair heat pump will provide you with years
of heated pool enjoyment. Heat pumps operate by
taking heat from the surrounding air and transferring
it into the water. The warmer the air and the more
humidity in the air, the more latent heat is available
for heating your pool. With a properly sized heat
pump for your pool, the heat pump should raise your
pool on average 1°F (-17°C) per hour depending on
air temperature, humidity, and water temperature.
The ideal or rated condition for the heat pump is
80°F (27°C) air temperature, 80% relative humidity,
and 80°F (27°C) water temperature. As conditions
decrease from 80/80/80, the heat pump performance
will decrease slightly.
Heat Pumps are best utilized to maintain a set water
temperature; they are not intended to provide instant
or fast heating. It is not reasonable to expect a heat
pump to perform like a gas heater which has a much
higher BTU output and faster response. Additionally,
gas heaters are not dependent on environmental
conditions. Swimming pool heat pumps are very similar
to home heating and air conditioning heat pumps and
therefore should be treated similarly.
Proper operation and use of the heat pump is to set
it at your desired temperature and leave it. Your heat
pump will turn on and off automatically to maintain your
desired temperature much like your home HVAC unit.
To take advantage of the sun's energy, operate your
heat pump during the heat of the day.
Your heat pump will still operate when the temperature
drops at night, but the output will be decreased. It is
acceptable to shut the heat pump off and not use it
for extended periods of time. When you have a need
to heat your pool, please plan accordingly since it
may take the heat pump days to heat your pool back
to your desired temperature, depending on your pool
temperature and environmental conditions.
Heat Pump Installation Requirements
Correct installation is required to assure safe operation.
The requirements for Pentair heat pumps include the
following:
• Dimensions for critical connections.
• Field assembly (if required).
• Appropriate site location and clearances (pages
2-3).
• Proper electrical wiring (pages 9-11).
• Adequate water flow (page i).
This manual provides the information needed to
meet these requirements. Review all application and
installation procedures completely before continuing
the installation.

BEFORE INSTALLING THE HEAT PUMP

General Installation Information

1. Installation and service must be performed by a
qualified installer or service agency, and must conform
to all national, state, and local codes.
2. Heat pumps get electrical power from an external
source and provide a dual electronic thermostat
control system for pool/spa combinations or preheat
convenience.
3. This heat pump is specifically designed for heating
fresh water swimming pools and spas. Do not use it as
a general service heater. Consult your dealer for the
appropriate Pentair products for these applications.

General Features

• Dual digital thermostats offer precise temperature control
to maintain the desired separate water temperatures in
pool/spa combinations without overheating or wasting
energy.
• Long-life corrosion resistant composite plastic cabinet
stands up to severe climates and pool chemicals.
• 100% pure titanium heat exchanger assures corrosion-
free performance for extra long life.
• Self-diagnostic control panel monitors and troubleshoots
heat pump operations to ensure safe, dependable
operation.
• Autoset (time clock over-ride) feature monitors water
temperature and turns the water circulation pump on and
off as needed to maintain desired pool temperatures.
• Extend (time clock over-ride) feature monitors water
temperature and turns the water circulation pump on and
off as needed to prolong a heating cycle that has been
interrupted.
• Automatic Defrost feature senses refrigerant temperature
and prevents the heat pump from freezing, allowing the
heat pump to operate at even lower temperatures.
• Compatible with all automated control packages. RS-
485 communication compatible with IntelliTouch
EasyTouch
Control Systems.
®
• Thermostatic expansion valve (TXV) controls refrigerant
flow for optimum efficiency and BTU output over a wider
operating range.
• Elevated base pan for positive drainage of condensation.
• 2-inch plumbing connections for easy installation.
• Separate isolated electrical compartment prevents
internal corrosion, extends heater life.
• Highest efficiency available, meets or exceeds existing
codes and standards.
• Adjustable timer allows the operator to set the heat
pump to run for a predetermined time. Incremental by 10
minutes to a maximum of 99 hours.
• An extensive list of operational conditions, alarms and
water temperatures are logged on the control board. This
information is available for the user to track performance
and troubleshoot issues.
