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. per
hour depending on air temperature, humidity, and water
temperature. The ideal or rated condition for the heat
pump is 80° F air temperature, 80% relative humidity, and
80° F 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.
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.
•
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.
•
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.
RS485 communication compatible with
IntelliTouch
®
and 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 to set the heat pump to
run for a predetermined time. Incremental by 10
minutes to a maximum of 99 hours.
BEFORE INSTALLING THE HEAT PUMP
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 8-11).
• Adequate water flow (page 6).
This manual provides the information needed to
meet these requirements. Review all application and
installation procedures completely before continuing
the installation
