3 Owners/users should contact the factory service department for advice at: Pentair Pool Products, Inc. (800) 831-7133 RETURN ON INVESTMENT The costs of installing a heat pump are somewhat higher than a gas heater but you will save enough in opera- tional costs to offset the dif ference, probably in the first year or two. After a few heating season[...]

5 W ARNING The heater must be electrically grounded and bonded in accordance with local codes, or in the absence of local codes, with the latest national electrical codes ANSI/NFP A No. 70. All wiring must comply with all local codes, or in the absence of local codes, with the latest national electrical codes ANSI/NFP A No. 70. For proper wire and/[...]

DUAL THERMOST A T CONTROL P ANEL THERMOST A T The thermostat dial is just like any other , when you set it at a certain setting the heater will heat up to that temperature and then shut off. When the pool/spa wa- ter temperature drops below this setting the heater will come on and start heating the water back up to the setting on the thermostat. Y [...]

7 POOL MODE "Y ellow": The yellow pool mode indicator light lets you know that you have selected the pool mode with the pool /spa select switch, (dual thermostat control only). This light will be of f when the control is in spa mode. SP A MODE "Orange": The orange spa mode indicator light tells you that you have selected the spa[...]

9 W A TER HEA T EXCHANGER The compressed hot gas releases its heat to the pool water inside the heat exchanger . The ex- changer is a tube within a tube construction, wa- ter passing through the inner tube, and the hot refrigerant passing through the outer tube. The refrigerant is transformed into a liquid (con- densed) state as it releases it&apos[...]

NORMAL RUNNING TIME The heat pump system extracts the heat from the out- side air and delivers it to your pool. Therefore it pro- duces more BTU's (heat) the warmer it is outside. So take advantage of the higher air temperatures during the day by setting the timer for the warmest hours. W in- ter operation (during cold fronts) may require long[...]

THERMOST A T SETTING There are no temperature reading numbers printed on the thermostat dial due to calibration changes from unit to unit. The demand for exact temperatures should be regulated by using a high quality thermometer right in the pool water . Normal temperatures for pools are 78 to 82 degrees F . Spa temperatures are 98 to a maximum of [...]

RERADIA TION CONVECTION EV APORA TION WIND CONDUCTION Pool Shell Pool Surface W arm Pool W ater UNDERST ANDING HEA T LOSS It is important to understand how your pool loses heat. The greatest heat loss occurs at the water surface. Y ou will need to adjust the operational time to compensate for added heat loss during the colder months. See the diagra[...]

CONTROLLING HEA T LOSS A good way to control heat loss is to slow the wind speed through your pool area by placing plants such as shrubs or bushes around the pool's perimeter . Plants will break up the air flow and diffuse the wind speed. If the pool area is to be fenced in, choose a wood shadow box type design. A solid type fence or wall does[...]

OWNERS MAINTENANCE & CARE There are some considerations that should be taken concerning the environment where your heater is installed. The heater is usually placed near the pool filtering system. There are certain things in this area you will need to be aware of to insure long life and prevent unnecessary damage. SPRINKLERS Make sure there are[...]

15 W A TER PIPING LEAK ? When the unit operates, it will produce condensation that will drain from the bottom of the unit. Do not mistake condensation with a water piping leak. There is a certain procedure to follow to check the unit for leaks: Shut the heat pump and filtering system off. Allow all the condensation to drain from the unit for at lea[...]

FIL TER CLEANING & CARE Y our filter system should be cleaned at least twice a month. See manufacturer's directions for proper filter cleaning methods. Size and conditions may require you to clean the filter more often. A filter is considered "dirty", whenever it restricts the flow rate by 10% or more. Y ou can use the pressure g[...]

Often times, when these auto vacuums begin to wear , they require more suction from the pump to operate. Diverting all vacuum through the auto vac may help it run better but will restrict the overall water flow through the entire system and the heater . If you have a low water flow situation where the heater is not getting enough water through the [...]

The heat pump in equipped with a internal "Automatic Bypass" valve. A variable rate spring valve is used to regulate the wa- ter flow through the heat ex- changer . Steady flow will be de- livered over a wide range of flow rates. This automatic valve can handle a maximum flow rate of 90 gallons per minute. The automatic valve will com- pe[...]

8" 2 LB CHEMICAL RESIST ANT CHECK V AL VE Part# 888-018 LOOP ABOVE TO POOL CHLORI- NA T OR FROM HEA TER The chemical resistant check valve and loop must be in- stalled with all types of chlorinators to prevent chlorine migration to the heater . The loop should extend at least 8 inches above the chlorinator top. The chemical resistant check val[...]

W A TER BALANCE MAINTENANCE The chemical balance of your pool/spa water and the methods used in adding pool chemicals will directly effect the life of your heater . Like no other precaution you could take, it is very important that these guidelines are followed in order to prevent damage to the heat exchanger/water coil and possibly the entire syst[...]

21 These chemical outlines should not be considered as a “how to” balance your pool/spa water , but just a refer- ence on how chemical balance effects the heater and gives suggested test values. Y ou should always consult a pool professional and follow all chemical manufacturers di- rections, unless they conflict with this manual. CHLORINE Chlo[...]

22 T OT AL ALKALINITY T otal Alkalinity is a test given to determine the over- all mineral content of the water . T otal alkalinity lev- els should be within the range from 90 p.p.m. to 120 p.p.m. The total alkalinity is described as a buffer against acetic conditions and acts as a stabilizer for the pH. It keeps the pH from fluctuating up and down[...]

CHLORINA TOR PLACEMENT 1. All chlorinators should have a chemical resistant check valve and a loop plumbed at least 8 inches above the chlorinator , between it and the heater , as far down line from the heater as possible. 2. Never plumb a chlorinator into the suction side of the circulation pump. All automatic chemical feeders should be as far dow[...]

24 COMMERCIAL FEEDERS W e strongly suggest that all chemical feeders be placed "down line" of the heater . In a "closely monitor ed" commercial pool situation where a vacuum type filter system is used in conjunction with a surge tank, there are some exceptions to chemical injection. Some liquid chlorine (sodium hypochlorite) fee[...]

25 SHUT DOWN & FREEZE PROTECTION PROCEDURES When shutting the unit down for the end of the swimming season, you must consider some items to protect the unit from inclement weather . It is best in most situations to shut the unit of f by turning the thermostat all the way down, to the "left". Leave power (cir cuit breaker), to the unit[...]

MANDA TOR Y BONDING T O POOL STEEL (This is in addition to electrical ground) Make sure that the unit cabinet is bonded to the pool steel. Most codes require that the circulation pump be bonded as well. Y ou can connect at that point using at least a #6 gauge or larger solid copper wire. Use the external bond lug on the cabinet to insure a good bon[...]
