IMPORTANT SAFETY PRECAUTIONS

Codes and Standards

The ThermalFlo HP heat pump is listed by ETL as complying with the latest edition of the “UL Standard for Safety for

Heating and Cooling Equipment”, UL 1995 and CSA C22.2 No. 236.

All Pentair Water heat pumps must be installed in accordance with the local building and installation codes as per the

utility or authority having jurisdiction. All local codes take precedence over national codes. In the absence of local

codes, refer to the latest edition of the National Electric Code (NEC) in the United States and the Canadian Electric

Code (CEC) in Canada for installation.

DANGER —Risk of electrical shock or electrocution.

The electrical supply to this product must be installed by a licensed or certified electrician in

accordance with the National Electrical Code and all applicable local codes and ordinances.

Improper installation will create an electrical hazard which could result in death or serious

injury to pool or spa users, installers, or others due to electrical shock, and may also cause

damage to property. Read and follow the specific instructions inside this guide.

WARNING —To reduce the risk of injury, do not permit children to use this product unless they are closely

supervised at all times.

WARNING —For units intended for use in other than single-family dwellings, a clearly labeled emergency

switch shall be provided as part of the installation. The switch shall be readily accessible to

the occupants and shall be installed at least 5 feet [1.52 m] away, adjacent to, and within sight

of the unit.

IMPORTANT SAFETY PRECAUTIONS (continued)

Consumer Information and Safety

The ThermalFlo series of heat pumps are designed and manufactured to provide many years of safe and reliable service

when installed, operated and maintained according to the information in this manual and the installation codes referred to

in later sections. Throughout the manual, safety warnings and cautions are identified by the “ “ symbol. Be sure to read

and comply with all of the warnings and cautions.

WARNING — The U.S. Consumer Product Safety Commission warns that elevated water temperature can be

hazardous. See below for water temperature guidelines before setting temperature.

WARNING — The following “Safety Rules for Hot Tubs” recommended by the U.S. Consumer Product Safety

Commission should be observed when using the spa.

1. Spa or hot tub water temperatures should never exceed 104° F. [40° C.]. A temperature of 100° F. [38° C.] is considered

safe for a healthy adult. Special caution is suggested for young children. Prolonged immersion in hot water can induce

hyperthermia.

2. Drinking of alcoholic beverages before or during spa or hot tub use can cause drowsiness which could lead to

unconsciousness and subsequently result in drowning.

3. Pregnant women beware! Soaking in water above 100° F. [38° C.] can cause fetal damage during the first three

months of pregnancy (resulting in the birth of a brain-damaged or deformed child). Pregnant women should stick

to the 100° F. [38° C.] maximum rule.

4. Before entering the spa or hot tub, the user should check the water temperature with an accurate thermometer. Spa

or hot tub thermostats may err in regulating water temperatures.

5. Persons with a medical history of heart disease, circulatory problems, diabetes or blood pressure problems should

obtain their physician's advice before using spas or hot tubs.

6. Persons taking medication which induce drowsiness, such as tranquilizers, antihistamines or anticoagulants should

not use spas or hot tubs.

Hyperthermia occurs when the internal temperature of the body reaches a level several degrees above normal body

temperature of 98.6° F. [37° C.]. The symptoms of hyperthermia include: drowsiness, lethargy, dizziness, fainting, and an

increase in the internal temperature of the body.

The effects of hyperthermia include:

1. Unawareness of impending danger.

2. Failure to perceive heat.

3. Failure to recognize the need to leave the spa.

4. Physical inability to exit the spa.

5. Fetal damage in pregnant women.

6. Unconsciousness resulting in danger of drowning.

Swimming Pool Energy Saving Tips

It is important to note that a heat pump will not heat a pool as fast as a large gas or electric pool heater. If the pool water is

allowed to cool significantly, it may take several days to return to the desired swimming temperature. For weekend use, it

is more economical to maintain the pool water temperature at or near your desired swimming temperature. If you do not plan

to use your pool for a prolonged period, then you might choose to turn the heat pump completely off or decrease the

temperature setting of the control several degrees to minimize energy consumption.

Pentair offers the following recommendations to help conserve energy and minimize the cost of operating your heat pump

without sacrificing comfort.

1. The American Red Cross recommends a maximum water temperature of 78° F. [25° C.]. Use an accurate pool

thermometer. A difference of 4° F. [2° C.] , between 78° F. and 82° F. [26° C. and 28° C.], will significantly increase energy

consumption.

2. Carefully monitor the water temperature of your pool in the summertime. You can reduce heat pump usage due to warmer

air temperatures.

3. During the winter or when on vacation for longer than a week, turn off the heat pump.

4. Find the proper setting on the heat pump temperature control and use the Keypad Lock function to discourage further

adjustments.

5. Set the pump time clock to start the pump no earlier than 6:00 AM during the pool-heating season. This is the time when

nightly heat loss balances.

6. Where possible, shelter the pool from prevailing winds with well-trimmed hedges or other landscaping, cabanas, or

fencing.

7. Always use a pool cover when practical. Besides providing a valuable safety feature, a pool cover will reduce heat

loss, conserve chemicals, and reduce the load on filter systems.

Introduction

ThermalFlo Overview

The ThermalFlo heat pump gets electrical power from an external source and provides a dual electronic

thermostat control system for pool/spa combinations or preheat convenience.

ThermalFlo HP heat pumps transfer the heat from the outside air to your pool, providing the most energy

efficient pool and spa heating available. Compared to gas, oil, or electric heaters, ThermalFlo HP heat pumps

operate up to 80% less, saving you hundreds of dollars in energy costs each year. Our heat pumps are not only

highly efficient, they’re also clean and safe to operate. ThermalFlo HP heat pumps are ETL-listed pool heat

pumps using R410-A, the environmentally safe and clean refrigerant.

The non-polluting ThermalFlo HP Heat Pump is so energy efficient, it will keep your pool comfortably warm

for far less than gas or electric heaters.

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 Water products for these applications.
