Water Chemistry

(Corrosive water voids all warranties)

For your health and the protection of your pool equipment, it is essential that your water be chemically balanced. The following levels must be used as a guide for balanced water.

Recommended Level(s) Fiberglass Pools Fiberglass Spas Other Pool & Spa Types

Water Temp. (Deg. F) 68 to 88 89 to 104 68 to 104

pH 7.3 to 7.4 7.3 to 7.4 7.6 to 7.8

Total Alkalinity (PPM) 120 to 150 120 to 150 80 to 120

Calcium Hardness (PPM) 200 to 300 150 to 200 200 to 400

Salt (PPM)

Free Chlorine (PPM)* 2 to 3 2 to 3 2 to 3

Total Dissolved Solids (PPM)

*Free Chlorine MUST NOT EXCEED 5 PPM! ** In salt water chlorinated pools, the total TDS can be as high as 6000ppm.

• Occasional chemical shock dosing of the pool or spa water should not damage the heater providing the water is balanced.

• Automatic chemical dosing devices and salt chlorinators are usually more efficient in heated water. Unless controlled, they can lead to excessive chlorine level which can damage your heater.

• Further advice should be obtained from your pool or spa builder, accredited pool shop, or chemical supplier for the correct levels for your water.

Warnings — Pay Attention to These Terms

ndicates the presence of immediate hazards which will cause severe personal injury, death

DANGER:

I or substantial property damage if ignored.

WARNING:

CAUTION:

NOTE:

This manual, as well as the pool/spa heat pump pool heater itself, contains ANSI-approved product safety signs and labels. Please read these signs and labels, as they convey important safety information about hazards that may be potentially present in and around the heat pump pool heater.

CAUTION: Elevated water temperature can be hazardous. The U.S. Consumer Product Safety Commission has these guidelines:

1. Spa 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.

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.

Indicates the presence of hazards or unsafe practices which could cause severe personal injury, death or substantial property damage if ignored.

Indicates the presence of hazards or unsafe practices which could cause minor personal injury or product or property damage if ignored.

Indicates special instructions on installation, operation, or maintenance which are important but not related to personal injury hazards.

CAUTION: Improper chemical content in a swim­ming pool or spa can damage the heat pump pool heater. DO NOT add pool chemicals to the skimmer. This will damage the heat pump pool heater and could void the heat pump pool heater warranty. ALWAYS follow the product manufacturer’s direc­tions when adding any chemicals to your pool.

WARNING: These heat pump pool heaters are charged with R-410A refrigerant. Ensure that all service work is done with gauges and equipment suitable for R-410A.

3. Pregnant Women Beware! Soaking in water over 102°F (39°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, users should check the water temperature with an accurate thermometer; spa or hot tub thermostats may err in regulating water temperatures by as much as 4°F (2.2°C).

5. Persons with a medical history of heart disease, circulatory problems, diabetes, or blood pressure problems should obtain a physician's advice before using pools or hot tubs.

6. Persons taking medications which induce drowsi­ness, such as tranquilizers, antihistamines, or anticoagulants, should not use spas or hot tubs.

Introduction

Installation Considerations

WARNING: This pool/spa heat pump pool heater is

an electromechanical machine that incorporates a

ressurized refrigerant gas in a sealed system.

p ONLY trained and qualified service personnel are

uthorized to install or service this equipment.

a 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 and troubleshooting of your new heat pump pool heater. This unit must be properly installed, maintained and operated for optimal per­formance.

This heat pump pool heater is an extremely efficient, economical machine designed specifically for swim­ming pool heating. It is similar in design and operation to a typical residential air conditioning system. The unit 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 heat pump pool heaters, compared to other types of heaters such as gas or oil-fired, this heat pump pool heater has lower heating capacity on a BTUH/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.

Place a cover or blanket over the pool at night and other non-use periods. This will keep evaporation, the cause of main heat loss, to a minimum, and will great­ly reduce pool heating costs. During warmer weather, the cover may be required only at night.

WARNING: Do not install the unit within 3 ft of

ossil fuel burning heaters. Air intake along the

f sides of this heat pump pool heater could disturb the combustion process of the unit, and could cause damage or personal injury.

• Mount the unit on a level, sturdy base, preferably a concrete slab or blocks. The size of the base should be at least 3 ft by 3 ft.

• You must install the 4 black rubber sound iso­lation pads (each 2 inches square) that ship with the unit. The pads are shipped in a bag with the unions, gaskets and the I&O manual. Install pads under the 4 corners of the unit to reduce vibra­tion and sound transmission to the base.

CAUTION: The unit’s supporting base must be high enough to keep it completely free of standing water at all times.

Situate the heat pump pool heater carefully to mini­mize installation costs while providing maximum efficiency of operation, and to allow adequate service access, as follows:

• For unrestricted air intake and service access, position each side of the unit at least 1 ft (30 cm) from walls, pipes and other obstructions.

WARNING: This unit is designed for outdoor instal­lation; DO NOT install it in an enclosed area such as a shed or garage.

• Recirculation of cold discharge air back into the evaporator coil will greatly reduce the unit’s heat­ing capacity and efficiency.

• This unit features an ‘up-flow’ discharge for quiet operation. Air is pulled up through the evaporator coil and discharged through the top grill. Allow at least 5 ft (1.5 m) clearance above the unit for unre­stricted air discharge. DO NOT install the unit under a porch or deck. Refer to Fig. 1.

• To minimize water piping, locate the unit as close as possible to the existing pool pump and filter.

• If the location of the heat pump pool heater is below the water line of the pool, the water pres­sure switch might need to be adjusted or an external water flow switch might be needed.

Fig. 1: Installation Clearances

• Irrigation water should be directed away from the heat pump pool heater-water spray can damage the heat pump pool heater.

• Rain water run offs- the heat pump pool heater can withstand normal rain. Install rain gutters to prevent direct steams of rain water to the heat pump pool heater.

• It is important to keep the area next to the heat pump pool heater clear of shrubs, bushes and chemicals containers. They could prevent air from circulating fully through the heat pump pool heater, and will affect the operation of the heat pump pool heater or damage the heat pump pool heater.

• When installed in areas where freezing tempera­tures can be encountered, drain the water circuit to prevent possible freeze-up damage. See the Freeze Protection Section.

• For high wind installation requirements, refer to the diagram on page 8.
