A NOTE TO YOU
Thank you for buying our Waterco Heat Pump Pool Heater
A heat pump pool heater is a highly efcient, cost effective method of pool heating. Intelligent operation and care
will result in many years of enjoyment and pleasure.
The Waterco heat pump pool heater is a self contained unit designed specically for pool heating. The unit
operates on the proven principle of heat pump technology. Using the latest technology in heat collection available,
the Earth and its atmosphere, the Waterco pool heater processes the sun’s free energy extracting heat from the
sun warmed air and transferring it efciently to the pool water. Because the Waterco pool heater moves the free
heat from the outside air to the pool water, rather than create heat, as a fossil fuel or electric resistance heater
does, the Waterco pool heater can heat your swimming pool with up to 80% lower operating costs than other less
efcient, while maintaining your water temperature at all times during the pool heating season.
In general, compared to other types of pool heaters such as gas or oil red, the Waterco pool heater has a lower
heating capacity on a kW/ hr basis. Therefore, it will be required to operate longer to accomplish the desired
results. At certain times, it may be necessary to run the heat pump up to 24 hours per day. However, this should
not be of concern to the owner because the heater is designed to operate continuously. Even though it may
operate continuously for many hours, it will still heat the pool with far greater economy than other types of
heaters.
As with all pool heaters, you are advised to use a pool cover at night and when the pool is not in use. This will
keep evaporation, the greatest source of heat loss, to a minimum, greatly reducing the overall pool heating costs.
During warmer weather, the pool cover may not be required.
Please complete and mail in the Ownership Registration Card provided at the end of this guide. The card helps
us to notify you about any new information on your heater.

INSTALLATION INSTRUCTIONS
Location
The location of the pool heater is very important in keeping installation costs to a minimum, while providing for
maximum efciency of operation as well as allowing adequate service and maintenance access.
The unit is designed for outdoor installation and should not be installed in a totally enclosed area such as a shed,
garage, etc. unless ventilation is provided to ensure adequate air exchange for proper operation. Re-circulation of
cold discharged air back into the evaporator coil will greatly reduce unit heating capacity and efciency.
The unit should be located as close as possible (3.0m is ideal) to the existing pool pump and lter to minimize
water piping. The use of 90 degree bends and short radius elbows in the water piping should be kept to a
minimum.
Mount the unit on a sturdy base, preferably a concrete slab or blocks. The base should be completely isolated
from the building foundation or wall to prevent the possibility of sound or vibration transmission into the building.
The size of the base should not be less than the base of the pool heater.
Contact your dealer to learn about our patio tile which ensures stability and reduces vibration.
Waterco models discharges air either from the top of the unit. Air is pulled through the evaporator coil and
discharge through the grille. Clearance should be allowed in front and around the unit for unrestricted air
discharge and service access. See Figure 1.
IMPORTANT
Water Piping
The piping sequence: pool pump / lter / heater / pool (inline chlorinators, if used, must be downstream (after
the heater) to minimise harm to the pool equipment). See “Caring for your Pool Heater” section for more details
on chlorination and chemical feeding. Rigid PVC piping is recommended, all joints should be glued with PVC
glue. If rigid PVC is not available, you can use soft or exible piping with stainless steel clamps. When the piping
installation is complete, operate the pool pump and check the system for leaks. Then check the lter pressure
gauge to see that excessive head pressure is not indicated.
NOTE: The installation of a bypass which isolate the heater from the water circuit is highly recommended. Make sure the
heat exchanger is not deprived of water circulation for several days, high chlorine gas could cause excessive
corrosion. If the disconnect switch is turned off, be sure the pool water is allowed to circulate through the unit, or
is drained out of it.
Plumbing Diagram
1. Any kind of Automatic Chlorination System MUST be installed after (downstream) of the Heat Pump.
2. Filter MUST be connected before (upstream) the Heat Pump.
3. A bypass should be installed on all systems for water ow adjustment and ease of service.
!
VITAL
When connecting the heater,
tighten the connections by hand
only. Too much pressure may
damage the water in or water
out of the heat exchanger.
IMPORTANT
Piping
The piping and plumbing between the heat pump and other equipment should be minimised. During colder
months, signicant heat loss will occur through the piping.

I pg 09
Heat Pump Swimming Pool Heaters
Flow Check Valve
This is concerned with the installation of heat pumps below the pool water level. The heat pump operates on a
pressure switch that activates the unit when the pool pump is switched on.
If the heat pump is installed more than 1.5 metres below the pool water level, the weight of the water keeps the
pressure switch activated and the heat pump running - even when the pool pump is switched off.
In this situation, to prevent the heat pump running when the pool pump is switched off, a ow check valve must
be installed in-line with the pressure switch.
The procedure on the following pages should be carried out: (This installation was carried out on a 105 three
phase model, but the same procedure applies to all models)
Installation Above Water Level
For installations where the heat pump is installed above water level, installers must ensure that sufcient water
ow is diverted to the heat pump. Flow is detected by the pressure switch. If the volume of water passing through
the heat pump is insufcient, the pressure switch will not activate and will not turn on the unit.
Bypass
A bypass must be installed with all heat pumps. This will allow the user to control the water ow through the unit,
as well disconnecting it easily for servicing.
Three Phase Connections
When installing the three phase heat pumps, the electrician must ensure at all times that the connections are done
according to the tags placed on the wires. The wiring is tagged: L1, L2, L3, and N.

It is essential that the electrician installing three phase heat pumps is present when the units are started up for
the rst time.
Wrongly connected heat pumps are indicated by the compressor running backwards, and making excessive
noise after the 3 minute time delay. This can damage the compressor if it is left to run.
If this occurs, the unit should be turned off immediately, and the wiring should be changed by swapping any two
(2) phases to x the problem - one phase needs to stay in the same position.
This is necessary as certain households/ properties may have three phase power supplies that are not wired to
Australian standards.
Electrical
To ensure your safety and ensure the adequate functioning of your heat pump, all electrical work should be
performed by a fully qualied and licensed electrician in accordance with local electrical codes.
An adequate and dedicated circuit breaker and copper wiring must be used. Refer to the electrical installation
diagram found on the inside of the access panel. It may be necessary to install a ground circuit breaker.

Bonding
Because all metals have different electrical potentials, ALL metal and electrical components of the pool system
MUST be bonded together. This includes the metal framework of the pool, the light, the pump, the lter (if metal),
the heater, any automatic chlorine generator, and any other metal or electrical equipment.
On some older pools, this substructure bond wire may not exist. In these cases, a 0.9 - 1.2m solid copper rod
must be driven into the ground near the equipment, all electric equipment and metal components must be
bonded to each other and to the copper rod. Warranty will be void if system is not properly bonded.

Heat Pump Swimming Pool Heaters
To Start-Up the unit
When the unit is turned on or after a power shut down, the panel lights up and either indicates OFF or the
temperature of the pool water circulating inside the heater. Program in the desired pool water temperature.
Once programmed the fan starts and the compressor starts after a 3 to 5 minute delay.
NOTE: The fan motor and the compressor will start at the same time when the unit has been stopped for a lond period.
To Start the unit
The unit can be stopped by switching off the electrical power supply or by programming the desired water
temperature below the actual pool water temperature.
Initial Heating
The speed of heating is dependent upon ve basic factors:
1. Size of the pool.
2. How many degrees the water is to be heated.
3. Ambient air temperature - the warmer the air the less time is required to heat.
4. Use of a solar blanket (see the following section).
5. The size of the heater.
To achieve initial heating your pool heater and pool pump may work up to 24 hours per day until desired
temperature is achieved. The initial heating time may vary depending upon the above ve factors. After initial
heating, operating time may be reduced to match daily heat loss.
Pool Solar Blanket
A pool solar blanket should be used whenever possible. Blankets minimise heat loss and conserve heat in your
pool. Like a jacket holds body heat in on a chilly day, or closed doors and windows hold heat in a home, the
blanket controls heat losses. Un-blanketed pools lose 2-3 times more heat than blanketed pools.
Heater Running Time
Most units should be sized to operate during the pool ltering cycle time of 8-12 hours daily, providing an even,
steady ow of warm water. On warmer days the heater will run less because the heat loss will be less. Heat pump
pool heaters are able to operate 24 hours per day when necessary.
Defrost Cycle
When the ambient air temperature is between 3˚C and 7˚C, or if the evaporator is dirty or clearances are not
respected, condensation water on the ns of the evaporator tends to frost. In such a case, the control will activate
the defrost cycle until all the frost is gone. A normal defrost cycle (compressor stopped) lasts between 5 and 10
minutes. The pool heater won’t be damaged if it is running at less than 7˚C. In these conditions, the unit will have
more frequent defrosting cycles.
Temperature Differential
It is possible for a temperature variation to occur between the probe and the pool thermostat measurement, due
the quality of the pool thermostat .i.e., the value displayed is different from the temperature displayed on the pool
thermometer. Example: if the water is at 26˚C and the heat pump displays 24˚C.
To calibrate this variation, perform the following procedure;
Read the pool water temperature (ex: 26.6˚C),
Now read the temperature displayed on the heat pump thermostat (24˚C),
To determine the differential subtract the pool water temperature from the heat pump temperature,
26 (80) -24 (76) = 2˚C. Therefore we must compensate for 2˚C.
To calibrate the probe perform the following procedure;
Enter the digital programming mode by simultaneously pressing on the up and down arrows,
Once the temperature displayed is ashing press on the ON/OFF button,
The display will now show the calibration value, which varies -4˚C,
Using the up and down arrows, enter the calibration value, 2˚C. The degree function will ash
for negative values and will not ash for positive values.
Once the calibration has been entered wait until the new temperature appears.

I pg 15
Heat Pump Swimming Pool Heaters
Winterising
Set the water temperature setting to OFF. Turn the pool heater breaker OFF. If the unit is stored in a place where
the temperature drops below the freezing point of 0˚C, it is mandatory that the water accumulated in the unit
be drained completely before freezing weather prevails. The water piping MUST be disconnected to drain
the heat exchanger in preparation for winter. Once the piping is disconnected, the unit MUST be drained of all its
water by tipping it (75˚). It is recommended to ush the inside of the heat exchanger with the garden hose and to
drain the unit again. Using 2 pool return caps, block the water in and water out to prevent any intrusion. Do Not
leave the water piping connected to the heater over the winter.
DO NOT put anything under the water connect ions of the unit to lift it up. This can keep water inside the heater
and cause freezing damages.
Unit may be covered for the winter. The use of a material that will allow air to go inside the heater is
recommended.
It is also possible to ll the heat exchanger with pool anti-freeze only, but ensure that the anti-freeze contains an
elevated pH to prevent corrosion. This is optional and requires appropriate hardware.

Protection Devices
The integrity and performance of your pool heater and its components is protected by controls. In normal use, the
Waterco unit should never reach the thermal protection level. However, should it happen, you should verify your
operating conditions as described below.
The Waterco unit is designed to operate with a minimum water circulation of 113lpm. The high pressure switch
will shut off the compressor if there is not sufcient water ow through the unit. Check for dirty lters, clogged
skimmers or the bypass valve position. They are usually the cause of this condition.
The Waterco unit also has a built-in water pressure switch that will interrupt the operation of your unit should
water circulation through the unit stop. If there is still a demand for heat, turn on your pool pump and the heater
will start up once the normal water ow is re-established.
Your heat pump pool heater features other protection devices that could stop the unit:
High pressure cut-out switch,
Low pressure cut-out switch,
Thermal protection for the compressor and the fan motor

I pg 17
Heat Pump Swimming Pool Heaters
There Is Water Around The Unit
While your Watero pool heater is in the heating mode, a large quantity of warm and humid air passes over the
evaporator and causes condensation.
It is normal to see condensation dripping under the heater.
To verify that the water is really a water leak you will need to stop the heater and leave the pool pump
running for over 5 hours. If water is still coming out of your heater after this period you should call Waterco
for service.
The Fan Is Running But Not The Compressor
The unit is in its 3 or 5 minutes time delay protection mode.
The unit is on defrost. The compressor will start again automatically a few minutes.
The Compressor Is Running But The Fan Is Not
If the unit was just installed and the compressor starts before you have programmed the desired temperature,
it is possible that the electrical hookup was made on the wrong side of the contactor (relay). Contact your
electrician.
The fan motor may be defective. Contact Waterco’s service dept.
TROUBLESHOOTING

GENERAL IMFORMATION AND TROUBLESHOOTING
Basic Troubleshooting Guide
HEAT PUMP TROUBLESHOOTING
Using a terminal block, connect the two stripped pressure switch wires into one end, and the blue and white
wires of the ow check valve into the other end as shown (it makes no difference in which way the blue and white
wires are plugged in)
Rubber Grommet
Cut and strip this pressure switch wire leaving two exposed ends.
Feed the ow check valve wire through the underside of the control box. A rubber gromment with some silicone
sealant should be used in the entry point here to prevent any damage to the wire.
The front plastic shell can be pulled back, and the ow check wire can be fed through the underside of the control
bax.
The screws from the front of the unit need to be removed. This allows access to the underside of the power box,
where the ow check valve wire will be fed through.
Pressure Switch
Soft metal cover that needs to be pushed open with a screwdriver.
Pressure switch wire that needs to be cut, this is where the ow check valve will be wired in series.
The valve must be installed horizontally, with the stem facing up.
During installation, it is best to use some form of ducting for the lead wire of the ow check valve, and have it
running along the ground (or even underground), to prevent any trip hazards.
