INSTALLATION GUIDELINES
IMPORTANT NOTICE: The following are the installation requirements that must be followed in order to meet
the general factory specifications. The installer may engineer other types of installation techniques that are suited for each particular installation, regarding placement and plumbing, but should still follow this basic format. The factory warranty will not warrant other field installed options unless factory parts are used according to this booklet. This information is intended for a licensed professional contractor only.
!
WARNING
The pool owner or operator should not attempt to perform or change any aspect of the installation, because serious bodily injury and or electrocution may result.

pitched no more than 1/4 inch away from the com­pressor end (front) of the heater. Pitch slab from
front to back 1/4" maximum and level from side to side. CONDENSATION DRAINAGE
The heat pump will precipitate water that drains from the unit at a steady rate while it is running. This con­densation is from the humidity in the outside air. The more humidity, the more condensation it will pro­duce. There are several drain ports in the bottom of
12" Min. Clearance On Sides
the unit, make sure they do not become clogged with debris.
HEATER ELEVATION
If the heater is to be installed more than 6 feet above, or more that 3 feet below the pool water level, you may need to install an external flow switch as shown in the plumbing section of this manual. If a solar system or special equipment is in use, you may re­quire either a special water pressure switch or the use of an external flow switch as shown in "Water Flow Switch Section",

SPRINKLER LOCATION
Relocate or remove any sprinkler heads that have the chance of spraying on or into the unit. are absolutely no sprinkler heads near the heater that will in any way spray on or into the heater. Sprinkler
damage is not covered under the warranty agree­ment. Make sure they are a sufficient distance away so
normal wind currents will not carry the mist to the heater.
The heater is designed to handle the wettest weather conditions that are typical of rain and humidity, etc. However, sprinkler heads force high pressure water into the unit from the side at an odd angle. Most sprinkler systems are connected to a well system. Most well water is high in minerals, sulphur and other aggressive con­taminates. These contaminates will leave a build up on the evaporator coils and electronics causing corrosion and hamper the efficiency. If you are located within 15 miles of the coast, salt may be in the well water also.
Make sure there
!
CAUTION
Chemicals should NOT be stored near the heater. The fan may draw corrosive chemical vapor through the unit causing damage. Do NOT store anything on top, under­neath or around the heater. You will need access to the disconnect breakers in the event of an emergency.
CLEANING
To clean the heater you should take a sponge and mild soapy water and wipe the surfaces clean. Do not use a pressurized garden hose to clean the heater. Never force water into the unit from any direction. You may use a garden hose at low pressure with no nozzle attachment to rinse the air coils. Pour a mild liquid soap into the water stream as you rinse the air coils. Clean the evapo­rator air coils at least 4 times a year. If you live near the sea coast, you will need to clean at least 6 times a year or more to remove salt and sand. Clogged evaporator coils will reduce the efficiency of the unit and cause corrosion. A professional should clean the coils peri­odically, every year or two.
ROOF CLEARANCE & RUN OFF
Be aware of roof slope and overhang above the heater. Sharp sloping roofs without gutters will allow massive amounts of rain water, mixed with debris from the roof to be forced through the unit. Roof valleys that collect run of f from two slopes are especially important to avoid. If space is limited, determine if a gutter or down spout is needed to protect the heater. Low roof overhangs may obstruct the air flow out of the unit and require 48 inches of clearance, See diagram below.

INTERNAL AUTOMATIC BYPASS
The heat pump in equipped with a internal "Automatic Bypass" valve. A variable rate spring valve is used to regulate the wa­ter flow through the heat ex­changer. Steady flow will be de­livered 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 com­pensate for flow loss due to nor­mal filter debris accumulation or changes if flow due to valving and other conditions.

EXCESSIVE FLOW BYPASS MANIFOLD FOR LARGE 2 H.P. PUMPS OR OVER 90 G.P.M.
If the pool circulation pump is over 2 HP OR if the total flow exceeds 90 GPM you will have to add the "excessive flow valve" as shown here. Do not install a bypass valve that will completely shut off flow to the heater, see "Shut­down Procedures".
Some larger water pumps may be restricted if the pipe size is not adequate therefore reducing its overall flow rate. When determining if you need an excessive bypass valve, one has to consider the hydraulic restriction of the filter, valving, amount of 90˚ fittings and the distance of pipe to the pool in the exist­ing filtering system. If you have a 2 HP water pump that does not exceed 90 G.P.M. considering the above, you may not need
the excessive bypass. Excessive water flow can damage the
heat exchanger. SPECIAL NOTE: See chlorinator place­ment instructions (Pg. 10).

The chemical resistant check valve and loop MUST be installed 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 valve should be placed on the pipe leading "up" to the chlorinator. Therefore, the weight of the water above the check valve will hold it closed even if the spring is weak or damaged. Mount the check valve as low as possible. Be sure to keep the chlorinator, pump and filter lid o­rings lubricated with silicone grease to insure a good seal. If it looses its seal, it will allow the chlorine to migrate to the heater when the system shuts off. The loss of vacuum will allow reverse flow.

!
Air leaks or suction leaks that allow air into the system will cause turbulence and damage to the sacrificial fittings. Cor­rect immediately ! Do not add isolation valves unless required for seasonal shut down & freeze pr otection procedures. Stag­nant water left in the heat exchanger can cause corrosion !
CAUTION
CHLORINATOR PLACEMENT & CHEMICAL USE
Chlorinator placement, water balance and where chemicals are added are very important aspects of installation. The failure to protect the unit from chemical damage which is not covered under the warranty.
PROTECT HEAT EXCHANGER
You want to prevent any chemicals from running through the piping and heat exchanger of the heater. Eliminate chlorinating devices which inject chlorine so­lution through the suction side of the filtering system, thus the chlorine passes through the heat exchanger at full strength before it has a chance to mix and dilute with the rest of the pool water. Do not add isolation
valves unless done for seasonal shut down & freeze protection procedures. Stagnantwater left in the heat
exchanger can cause corrosion !
CHLORINE MIGRATION
Some chlorinating devices will back siphon when the system is shut off, therefore allowing the chlorine solu­tion from a chlorinator to flow through the heat ex­changer causing damage. You have to make sure your filtering system does not have a vacuum leak that would allow the system to lose prime. When this happens, water will move backwards through the chlorinator thus moving the chlorine solution into the heat exchanger.
CHLORINATOR PLACEMENT
A) 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.
B) Never plumb a chlorinator into the suction side of the circulation pump. C) Do not use chemicals through the skimmer basket. D) All automatic chemical feeders should be as far down line of the heaters water flow as possible. E) Off line type chlorinators should be tapped into the plumbing only as shown on the diagram. See pool/spa combinations that require special place­ment. F) Do not install a chlorinator in at a higher eleva­tion than the heater itself even if a loop and check valve is used. This may allow chlorine to migrate to the heat exchanger. Chlorinator should be the low­est point in the system.
ADDING CHEMICALS
Do not place any chemicals in the skimmer throat. Chlorine tablets placed in the skimmer will allow a concentrated solution of chlorine to pass through the heat exchanger. Do not place any chemicals in the pump lint trap cavity or filter. Do not over load chlorinator feeder cavity. Excessive amounts of chlorine tablets will increase the chance of migra­tion of acidic and concentrated chlorine to the heat exchanger causing damage. 25% of maximum is suggested. When adding any chlorine make sure that the pH does not drop below 7.4 and the alkalinity does not drop below 90 p.p.m. Fiberglass pools, spa & liner pools PH & chlorine levels are difficult to maintain. Please be advised heater damage may occur if mini­mum water balance levels are not maintained.
COMMERCIAL FEEDERS
In a commercial pool situation where there is a vacuum type filter system is used in conjunction with a surge tank, there are exceptions to chemical injection. Some liquid chlorine (sodium hypochlorite) feeders and liq­uid muriatic acid feeders will inject their solutions into the surge tank on the suction side of the unit. As long as the liquid chlorine and, muriatic acid is diluted with 75% water in a supply tank and fed at a slow enough rate, you can allow this type of chemical injection to take place. As long as the water in the surge tank has not conflicted with the chemical values described in this booklet. You should test the surge tank while the feeders and circulation pumps are running, just as you would the pool water. Then adjust the solution or rate of feed accordingly.
Never place chlorine tablets in the surge tank. Never
allow a tablet type chlorinator to inject solution into
the surge tank under any circumstance.

STANDARD PLUMBING 1 OR 2 UNITS
The following diagram is for standard plumbing of either one or two units. Plumb the unit in "after" the filter and "before" the chlorinator. SPECIAL NOTE: See chlorinator placement instructions in this manual (Pg. 10). Be advised that if your circulation pump is over 2 HP OR if the total flow exceeds 90 GPM, you will have to add the "excessive flow valve" as shown below. Some larger water pumps may be restricted if the pipe size is not adequate therefore reducing its overall flow rate. When determining if you need an excessive bypass valve, one has to consider the hydraulic restriction of the filter, valving, amount of 90˚ fittings and the distance of pipe to the pool in the existing filtering system. If you have a 2 HP water pump that does not exceed 90 G.P.M., considering the above, you may not need the excessive bypass See the diagram shown at the bottom of this page.

POOL & SPA COMBO PLUMBING
Heating a connected pool and spa spill over with one heater. For a single pump system.
The following is a schematic of the suggested plumbing set up when using the standard dual thermostat kit. This design is used for pool/ spa combinations where the pool and spa are connected via a spill over, when one filtering pump is used to circulate the water to either the pool or spa. The motorized valves turn to isolate the pool or spa when the dual thermostat is activated by the user. The motorized valves shown, can be manual if automatic operation is not desired. See "Dual Thermostat Kit". Note the chlorinator placement to protect the heater. A separate hydrotherapy pump is suggested for newly constructed pools to eliminate restriction to the spa jets.
Remember
::
: If the water pump is larger than 2 HP the excessive water flow valve may be needed.

SEPARATE POOL & SPA PLUMBING
Heating a separate pool & spa, "without" a spill over, with one heater. Two pump system.
The following schematic is the suggested plumbing set up when using the dual thermostat kit. This design is for "separate" pool and spa combinations, where the two are totally isolated from one another. The motorized valve turns so that the heater is isolated to either the pool or the spa when the dual thermostat is activated by the user. The motorized valves shown can be manual if automatic operation is not desired. Please note the 10 pound spring valve and ball valve used as a bypass when the valves are turning. This will eliminate the possibility of "dead heading" by the user.
NOTE: An exchange of water between the pool & spa may occur. This will depend on pump size, pipe size and equipment distances. The possibility of the spa flooding over or draining should be considered. Most commercial pool/spa codes do not allow this type of plumbing set up.

PLUMBING WITH SOLAR PANELS
Always plumb through the heat pump first before plumbing to solar. If the water flow is not adequate to provide proper flow for both, you will have to operate one or the other by adjusting the 3-way valve accordingly or increase your pumps size. Low water flow to the heat pump will cause the unit to cycle on & off. In some cases an external flow switch may have been installed in place of the existing pressure switch, if the draining of the solar panels effect the heater. A special use water pressure switch may be substituted for the factory water pressure switch in most cases, call the factory for advice. The static pressure created by the solar panels may allow the unit to operate without water flow.

SPECIAL NOTE: Do not run water through the solar panels at night or on very cloudy days. This will have a cooling effect and counteract the heat pumps heat input to the pool water. There should always be a vacuum relief valve on the solar panels to eliminate static pressure. Do not run the solar and the heat pump when there is no
available heat coming from the solar. The user must manually turn solar off & on if there is no automatic device installed by the solar contractor. These automatic solar switching devices are usually optional.
15
COMMERCIAL PLUMBING
When plumbing a heating system into a high rate commercial filtering system, you should be prepared to evaluate the entire system in order to accommodate the heaters. The control of the water flow is most critical. The more planning done prior to this type of installation will prevent service problems later.
PLACEMENT AREA
Inspect the placement area and be sure that the pip­ing does not obstruct any serviceable items such as electric or other utilities. When installing multiple units, be sure to allow enough spacing for proper air flow. You do not want the units competing for air flow.
CHEMICAL FEEDERS
Inspect all chemical feeding devices and storage tanks. Follow the chemical feeder and chemical in­troduction guidelines described in this manual. The life of the unit depends on you following these suggestions to prevent chemical damage to the unit. Keep chemical storage tanks well away from the units so that the chemical vapor is not drawn into the unit
FLOW METERS
We strongly advise the use of flow meters when in­stalling on a commercial application. The usually higher water flow must be controlled. When in­stalling flow metering equipment to gauge water flow, be sure to follow the manufacturers directions to the letter. There are certain pipe length require­ments, before and after the flow meters placement. An improperly placed or sized flow meter will give a false reading.
WATER FLOW SEQUENCE
Water is drawn into the filter surge tank from the pool. The circulation pump forces water to the diverting valve. The diverting valve is partially closed in order to force a certain amount of water through the heater plumbing manifold. The diverting valve is closed until the proper flow rate is indicated on the flow meter.
You should set the diverting valve so the flow meter reads approximately 35 to 40 G.P.M." More flow may be required depending upon hydraulic restriction and "feet of head" on the filtering system. Special considerations must be made to insure proper flow rate to the heater(s).
The water flow is diverted to the heater's internal bypass where it is automatically adjusted as long as the proper flow rate has been set at the main diverting valve. The internal bypass will regulate the water flow through the heat exchanger. This water is heated and returned to the main water flow. The balance of the water is "bypassed" and returned to the main water flow.
A flapper check valve is used to prevent the possibil- ity of reverse flow. The shut off valves are used to isolate the heater from the water flow for servicing and may be required by local codes.
A loop 8 inches above chlorinator (or other chemical injectors) and the 2 to 5 lb. check valve will prevent chemical damage to the heater. See page 10 and 11 for the required chemical damage protection precautions.
per heater".
INDEPENDENT BOOSTER PUMP
In some situations, it will be necessary to install a booster pump that will provide the water flow needed for the heaters. This pump will be indepen­dent of the circulation pump to prevent filtering re­striction. They should be wired on a relay so they both run together . Call the factory for advice. Booster pumps should be used when the heaters are installed too far away from the filtering system or if the heat­ers are at a different elevation than the pool or if the filtering system is not capable of providing good flow at all times, to satisfy the health department.
Keep all chemical and chlorine feeders as far down line from the heater as possible to prevent the possibil­ity of corrosion to the heater.

OPTIONAL WATER "FLOW" SWITCH
Some installations require an external water “FLOW” switch in place of the water “PRESSURE” switch. This switch will keep the unit from running without water flow.
BELOW WATER LEVEL
If the unit is installed three feet or more below water level, the pressure switch will be effected by static pres­sure. This static pressure may cause the “pressure" switch to stay activated thus allowing the unit to run when the water flow stops. You then may require the external flow switch or the special use water pressure switch.
LONG RUNS & LOW FLOW
The "flow" switch or special water pressure switch may be needed on systems when the heater is installed more than 30 or 40 feet from the circulation pump. Weak or heavy load filtering systems will slow the water flow and cause the standard water pressure switch to cycle.
SUCTION LEAKS
Be advised that suction leaks that allow air into the sys­tem will cause erratic operation of the water "pressure" switch and water "flow "switch. The air turbulence causes the switch to malfunction.
SOLAR PANELS
If you have a solar system plumbed in the same system as the heat pump, you may experience static pressure on certain brands of solar panels. Often times the pres­sure switch will detect back pressure created from el­evation of the solar panels.
Some solar systems may reverse flow (drain) when the circulation pump shuts off. This may cause problems with the internal "pressure" switch. In some cases you may have to add check valves to control the reverse flow. Check with the solar panel manufacturer or in­staller before using check valves. Make sure that your solar system is capable of draining into the pool, via a vacuum relief valve.
These and other conditions may require the use of this added type of flow switch or special use water pressure switch. Reverse flow and static pressure may allow the unit to run without water flow or cycle off and on, causing damage.
The added “flow” switch only detects water movement and will not be effected by static, low or high pressure, therefore, it is best suited in these situations.
18
WATER FLOW SWITCH INSTALLATION
In most cases the existing water pressure switch located inside the access compartment can be changed to this spe­cial use water pressure switch. This water pressure switch can be set at a higher rating to offset the static pressure in some cases. The factory part number is #408. Install this switch in place of the existing water pressure switch when needed. If it does not solve the static pressure problem then use the optional Grid™ flow switch. The factory part num­ber is #888-032.
See "Water Pressure Switch" for more information re­garding the water pressure switch.
Plumb the optional water FLOW switch externally on the water

Then connect them to an insulated two pair cable with 14 to 12 gauge wire.

net and wire accordingly. Make sure all connections are water tight. Use the proper slip connectors. Leave the existing water pressure switch in place or remove and replace with a 1/4 inch machine threaded "copper" or "p.v.c." plug. Use teflon tape and pipe sealer.
Start the circulation pump and heater. Adjust the set screw clockwise until the unit shuts off. Then turn the set screw clock­wise until the unit starts, then add three more turns clockwise.
Test run all equipment that may slow the water flow and readjust as needed. Make sure the heater shuts off when the circulation pump does.

NOTE: COMPRESSOR TIME DELAY
BE AWARE THERE IS A 5 TO 7 MINUTE TIME DE­LAY BEFORE THE COMPRESSOR WILL START ONCE THE UNIT IS TURNED ON OR WHENEVER IT RESTARTS.
SET THE WATER PUMP TIMER
Set the circulation pump timer for 24 hours until the pool reaches temperature. Then it can be reset for 8 to 18 hours per day, depending on pool size and weather conditions, time of the year, some fall/winter condi­tions may require a 24 hour run time.
CHECK FLOW AT AUTO BYPASS
Make sure the pump is running with a full prime. Elimi­nate any suction leaks that allow air into the system. Confirm that the internal automatic bypass valve is work­ing properly. Turn the power to the heater "OFF" Confirm there are no air leaks at the pump skimmer basket. The auto valve should have no air passing through it. Air pumped through the heater due to a suction leak on the existing pool filtering system will cause turbulence and physical erosion to the heat exchanger.

OPERATIONAL SEQUENCE
WATER FLOW & EXISTING WATER PUMP
To filter the pool water each day, the water pump will come on & off according to the existing timer device. The heater will only heat if there is water running through it and it op­erates long enough.
WATER PRESSURE SWITCH
When water starts flowing through the unit the water pressure switch will activate and allow the unit to run. When the circulation pump timer stops the water flow, the wa­ter pressure switch will shut the unit off. When the pump restarts for the next day, the pressure switch will activate and allow the heater to run again.
THERMOSTAT CONTROL & SETTINGS
Turning up the thermostat will start the unit. When the pool water has been heated to the thermostat setting, the unit will shut off. When the pool water temperature loses one to two degrees, the thermostat will activate the unit. There are no temperature graduate numbers printed on the thermostat face. To obtain an exact temperature for a pool, turn the t-stat 3/4's of the way up and then place a pool type thermometer in the pool water itself. Once the water has reached your target temperature on the thermometer, turn the thermostat knob backwards until the heater just shuts off. There­fore your thermostat will be set at the thermom­eter reading.
THERMOSTAT CONTROL & SETTINGS FOR HEAT & COOL MODELS
For heating mode on these models, make sure toggle is selected to heat and follow the pre­vious instructions above. For cooling mode, make sure toggle is selected to cool. Turning down the thermostat counter clockwise will start the unit running. When the pool water has been cooled to the thermostat setting, the unit will shut off. When the pool water temperature rises one to two de­grees, the thermostat will activate the unit. There are no temperature graduate numbers printed on the thermostat face. To obtain an exact temperature, turn the t-stat all the way down and then place a pool type thermometer in the pool water itself. Once the water has reached your target temperature on the thermometer, turn the thermostat knob forwards until the heater just shuts off. Therefore your
thermostat will be set at the thermometer reading.

FAN-AIR CIRCULATION
Once the t-stat is activated the fan will begin to turn. To collect the heat from the air, the fan circulates warmer air through the evaporator air coil at about 4200 cubic feet per minute. The fan runs independently from the compressor. The compressor will start within 5 to 7 minutes after the fan.
EVAPORATOR AIR COIL
The fan circulates the warmer outside air through the evaporator air coil to collect any available heat. The cooler refrigerant ab­sorbs this heat. This evaporates the refriger­ant into a gas. Therefore the compressor can compress the gas to maximize the gained heat from the air.
COMPRESSOR
Once the fan is running, the compressor will start 5 to 7 minutes later and is controlled by a time delay device. The compressor pumps and com­presses refrigerant gas. When gas is compressed it gets very hot and intensifies the energy and then is released to the pool water. This com­pressed hot gas is pumped through the heat ex­changer where it delivers heat to the pool water passing through the same heat exchanger.
WATER HEAT EXCHANGER
The compressed hot gas releases its heat to the pool water inside the heat exchanger. The ex­changer is a tube within a tube construction, water passing through the inner tube, and the
hot refrigerant passing through the outer tube. The refrigerant is transformed into a liquid (condensed) state as it releases it's heat to the pool water. Therefore, it is also referred to as a condenser coil. The alloy exchanger is de­signed for maximum transfer surface area and strength.

WATER PRESSURE SWITCH CHECK
The water pressure switch is preset at the factory and should only be adjusted "if needed". The water pressure switch is designed to shut the heater off when the water circulation pump shuts of f. The water
pressure switch will keep the unit from running when there is no water flow. The water pressure switch has a 1 to 5 psi pressure range on water pressure rise or fall.
After you have plumbed and wired the heater, you should check to see if the heater will shut off when the circu­lation pump shuts off. Also, test run other pool equipment (automatic pool vacuums, spas, solar panels, etc.), that may restrict the water flow. If the heater stops running when these items are operating, you may have to adjust the water pressure switch to compensate for flow restriction. The unit will suffer severe damage if it operates without enough water running through the heat exchanger. If the system will not work due to low or fluctuating water flow with the above mentioned items, you may require another optional, external water "FLOW" switch (part# 888-032) OR a special use pressure switch (part# 408). A "flow" type switch can be used in place of the existing water pressure switch inside the unit.
If the heater does not shut off when the circulation pump does, or the heater cycles off and on, there may be a problem in the filtering system or other equipment creating back pres­sure on the system. Items such as solar panels, units in­stalled above or below water elevation or suction leaks caus­ing water to back siphon through the unit, may keep the pressure switch engaged. Determine what can be done to improve water flow to accommodate the addition of the new heater.

The water pressure switch is preset at the factory and should only be adjusted slightly by one to two turns maximum, in either direction. Adjust only when the heater does not shut off with the water circulation pump.
Turn the adjustment clockwise and the switch will require "more" pressure rise or drop to activate and deactivate the heater.

CAUTION
NOTE: Be careful not to turn the adjustment knob too far counterclockwise or the adjust­ment knob and internal spring may come apart.

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 off by turning the thermostat all the way down, to the "left". Leave power (circuit breaker), to the unit “on” unless the pool or spa water temperature
drops below 50 degrees F.
SHORT TERM FREEZE PROTECTION PROCEDURES When the outside air temperature is forecast to drop below 32 degrees F for a short time:
You should set the circulation pump timer to run 24 hours per day in order to circulate water through the unit and filtration system. Standing water inside the piping will freeze and damage the water heat exchanger and refriger­ant system. Shut the heat pump off and do not try to heat the pool during freezing temperatures. If the unit is left running it may ice up and the compressor will stop running. The defrost control inside the unit will shut the compressor off, but allow the fan to run. The fan will circulate air through the unit to help defrost the evaporator air coil. If you know that the temperatures are going to be below 36 degrees F, you should eliminate the possibil­ity of icing and just shut the unit off. Do not use the circuit breaker as the “on/off” switch, if you want to shut down for a long period of time use the discconnect. (See page 27)
LONG TERM FREEZE PROTECTION / DRAIN VALVE INSTALLATION If you live in a climate that has a seasonal swim season due to winter, you should follow these long term freezing procedures.

(Hose bibb)

IN
2-way
Shut Off
Valves
Shut the water pump off. Close both shut off valves. Open both drains and allow water to exit. Use pressurized air on the water in, one spigot only, to force the rest of the water out the other spigot.
If you live in an area that experiences freezing temperatures, the heat exchanger/water coil and bypass plumbing must have all water removed to prevent freeze and chemical dam­age to the heat pump system. This procedure should be done prior to the first freeze along with your other pool winteriz­ing routine. When you drain the filter system and piping you should include the heat pump as well.
There should be two spigot type drains, (hose bibbs), plumbed into the heater's water in and water out piping. Place these valves as close to the heater and at the lowest point possible so as much water will drain as possible. Install two shut off valves on the water in and out lines as shown here. The rest of the water should be blown out with pressurized air to insure all water is removed. A antifreeze designed for pool equipment may be used, see a local pool professional.
!
CAUTION
Do not add isolation valves unless you intend to clear the heat exchanger of water with pressurized air! Stagnant water left in the heat exchanger can cause corrosion and will freeze causing damage!

ELECTRICAL WIRING GROUND &
EQUIPMENT COMMON BONDING
A certified electrician should prepare to wire the heater according to national, local codes and specifications from the factory in regards to supply voltage and amperes. Most codes require that a power disconnect be placed near the heater for emergency shut off.
!
WARNING
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/NFPA No. 70. All wiring must comply with all local codes, or in the absence of local codes, with the latest national electrical codes ANSI/NFPA No. 70. For proper wire and/or breaker size, please refer to specification sheet and your local licensed electrician.
REQUIRED BONDING TO POOL STEEL
Make sure that the unit cabinet is bonded to the pool steel. Most codes require that the circulation pump be bonded as well. You can connect at that point using at least a #8 gauge or larger solid copper bond wire. Use the external bond lug on the cabinet to insure a good bond.

START CAPACITOR FOR 208 VOLTAGE
The compressor must be protected from low voltage situations to meet the warranty requirements. A unit drawing high amps due to low voltage, is not consid­ered a proper installation. Contact the factory service for advise about low supply voltage. Many coastal com­munities have 208 volts. 208 volt supply requires
changing transform leads to 208V from 240V, see wiring schematic.
TIME DELAY COMPRESSOR
NOTE: The compressor will attempt to start after a 5 to
7 minute time delay has passed from when the unit was activated. If the compressor starts then shuts right off, allow the 5 to 7 minute time delay to pass before expect­ing the compressor to start.
Inform the owners not to use the circuit breaker as the on/off switch or the unit will not preheat as needed between cycles. Turn the thermostat all the way down when you do not want the unit to heat.

Required Transformer Line Side Leg Change for 208 Voltage
The high voltage side of the 24 volt transformer must be rewired for 208 voltage. The orange 240 volt lead should be swapped with the unused red 208 volt lead connected to the line side of the main contactor. If the transformer is not rewired, the transformer will not produce an adequate amount of voltage to operate the contactor coils in the various relays of the heater. This can cause intermittent contact and damage to the compressor and contactors. Trace the orange wire to the terminal board, remove it and replace it with the red wire. Cap and secure the orange wire.
NOTE: If the unit has the factory optional dual thermostat kit and motorized plumbing valve kit, you must rewire the transformer on the motor valve kit as well. Damage due to improper low voltage instal­lation is not covered under the warranty.
