A NOTE TO YOU
Congratulations!
Thank you for choosing a Waterco Electroheat ECO-V inverter heat pump to heat
your pool.
Using the latest technology in heat capture, the Waterco pool heat pump converts
the energy released by the sun and transfers it efficiently to your swimming pool.
During certain periods it may be necessary to operate your pool heat pump
continuously during the day in cooler periods however, this should not be of concern
as your Waterco pool heat pump can heat up your pool approximately 80% more
economically than the fossil fuel heating or heaters with electric elements. Waterco
pool heat pumps are designed specifically to heat or cool your swimming pool
economically.
To appreciate the benefits this product will bring you, make sure to operate the unit
when the atmospheric conditions specified in this document are present in addition
of using a solar blanket to minimize heat loss which will influence operating costs and
size of the unit required. Pools not covered with a solar blanket lose 2 to 3 times more
heat, regardless of types of heating!
This manual applied to the following models:
Electroheat ECO - V inverter 5kW heat / cool with auto evaporator deicing

INSTALLATION INSTRUCTIONS
Location
To gain maximum efficiency for your pool heat pump please follow all instructions
when “positioning the unit”. It is also important to allow clearances for future service
and maintenance procedures.
The unit is designed for outdoor installation and should not be installed in a totally
enclosed area such as a shed, garage, etc., unless ducted and fan assisted ventilation
of the cold exhaust air is provided to ensure adequate air exchange for correct
operation.
The unit shall be sited in a well ventilated area in order to avoid trapped cold discharge
air. Re-circulation of cold discharged air back into the evaporator coil should be
avoided and will greatly reduce unit’s heating capacity and efficiency.
The unit should be located as close as practically possible to the existing pool pump
and filter 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 arranged to
support the whole length of the unit. 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 heat pump.
Use of anti vibration mat between the base of the unit and final installation location
material is highly recommended to reduce potential vibration noise issues.
Fitting the two supplied drainage spigots to the rear of the base must be installed
prior to final installation of the unit.
The unit should be maneuvered into its final position and the anti vibration mounts
(supplied by installer) fitted under each foot.

Figure 1
Installation Clearances
Air is pulled through the evaporator coil and discharged from the top grill. Clearances
must be allowed in front and around the unit for unrestricted air discharge and
service access. See Figure 1. Failure to comply to the set clearances may cause
diminished unit performance and reduced unit longevity.
Clearance to rear minimum 30cm
Clearance to side
minimum 60cm
Clearance to side
minimum 60cm
No obstruction to front
2.5m minimum

Water Piping
The supplied plumbing layout must be followed without exception:
1. pool pump
2. filter
3. pool heat pump
4.chlorinator (when installed).
Rigid PVC piping is recommended with all joints primed and glued with a suitable PVC
adhesive cement. If rigid PVC pipe is not available,a suitable flexible hose of adequate
diameter may be utilised with stainless steel clamps. When the piping installation is
complete, operate the pool pump and check the system for leaks. Then check the
filter pressure gauge to see that excessive pump head pressure is not indicated.
Water Flow Rate
The recommended water flow rate range varies depending on the size of the heat
pump to ensure maximum heat transfer efficiency is within the specified limits. The
optimal flow rate is the mid point of this range. Use the bypass valve to adjust the
flow rate to within the recommended range. See Performance Specifications table
page 13.
Water By-pass Kit
A bypass kit consisting of 3 X two way valves must be installed for adjustment of
water flow and ease of service. Waterco offer prefabricated water bypass kits to fit
their heat pump domestic range. Ask your local Waterco sales office for details.
07 I Pool Heat Pump

Pool Heat Pump I 08
1. A check valve or a loop MUST be installed between the pool heat pump and any
automatic chlorinator to prevent highly chlorine concentrated water from flowing
back to the pool heat pump when the pool pump is not running.
2. These units are fitted with a flow switch which are not effected by water pressure.
Therefore, the fitment of a flow check valve due to the installed height either
above or below water level is not required.
3. For units installed above the pool water level the return water to the pool valve on
the bypass valve set should be closed approximately 15-20% to ensure the heat
exchanger is completely full of water to allow the heat transfer to occur.

Electrical
All electrical work should be performed by a fully qualified and licensed electrician
in accordance with local electrical codes.
An adequate circuit breaker and copper wiring must be used. Electrical requirements
are available on the name plate of the pool heat pump. It may be necessary to install
an earth leakage circuit breaker.
Waterco recommend connecting the unit to an isolating switch to allow ease of
service and maintenance.
Electrical Connection
Standard 60 Hz power supply : 208/240 v - 60Hz-1 phase
Standard 50 Hz power supply : 208/240 v - 50Hz-1 phase
Breaker Size
Please consult name plate on the base or the side of your pool heat pump for starting
amperage and required breaker size.
Electrical Wire Size
Please consult a qualified and licensed electrician.
THE POOL HEAT PUMP MUST BE DISCONNECTED BEFORE
OPENING THE ACCESS PANEL.

The power cable ground must be connected to the electrical
panel and to the ground lug of the pool heat pump. An
improper installation may be a potential cause of fire,
electrical shock or injury.
!

Pool Heat Pump I 10
Bonding
In some locations bonding of the pool equipment and pool substructure may be
required by law. 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 filter (if metal), the
pool heat pump, any automatic chlorine generator, and any other metal or electrical
equipment bonded to your pool.
On some older pools, this substructure bond wire may not exist. In these cases, a 3-4
foot solid copper rod must be driven into the ground near equipment; all electric and
metal components must be bonded to each other, and to the copper rod. Warranty
will be voided if system is not properly bonded.
CAUTION: Some of these systems may leak stray voltage and currents into the
water causing severe electrolysis. This dramatically shortens the life of the pool
heat pump and will void the warranty.
When an automatic chlorinator is installed on a pool circulation system, it is
important the equipment is correctly installed and bonded (earthed). Some systems
may leak stray voltage and currents into the water causing severe electrolysis which
could shorten the life of the pool heat pump.
NOTE: Bonding to pool pump is not required to above ground pool pumps but all
other equipment must be bonded.

Manometer Instruction
Refrigerant Charge Indicator Gauge
The refrigerant charge gauge is provided to monitor the refrigerant charge within
the heat pump. When the heat pump is operating, the gauge needle would point to
the pressure value of refrigerant with the maximum value of protection of 42kg/Cm2.
When the heat pump is off, the gauge needle would point to the same value as actual
ambient temperature (e.g. 28°C) and related air pressure (e.g. 18kg/Cm2).
If the needle is pointing in the range of 0 - 3 then it may indicate low refrigerant
charge and should be checked by a qualified technician.

Adjustment Of The Bypass Valves
Waterco ECO-V pool heat pumps do not require the water by pass valves adjusted
to cope with cooler water temperatures. In the event of low water temperatures, the
ECO - V inverter pool heat pumps increase the operating frequency of the compressor
which in turn increases the output capacity of the unit.
It is essential water flow through the unit is within the range specified in the
Performance Specifications table opposite. The bypass valve may be used to tune
the water flow within range.
The adjustment may vary according to pool pump size.
OPERATION OF YOUR POOL HEAT PUMP
Initial Heating
To achieve initial heating, your pool heat pump and the pool pump may require
extended operation until desired temperature is achieved. The initial heating time
may vary depending upon the five factors listed below. After initial heating, operating
time may be reduced to match daily heat loss.
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 required to heat.
4. Use of a solar blanket.
5. The size of the pool heat pump.
If a combination of the atmospheric and water temperatures are below the minimum
listed concurrently the pool heat pump should not be operated and be switched off.
Generally, atmospheric conditions (air temperature) will be warmer during day time
hours. To accelerate the initial heating period owners may opt to increase the ambient
air temperature artificially around the evaporator area of the pool heat pump until the
pool water temperature has reached the minimum required as stated below.
Pool Heat Pump I 14

Pool Heat Pump Running Time
Most units should be sized to operate during the pool filtering cycle time of 8-12
daytime hours daily during warmer months and up to 8 hours daily during the
daytime in winter months. On warmer days the pool heat pump will run less because
the heat loss will be less.
Condensation
Your pool heat pump will accumulate condensed water (approx. 4 to 6 litres or
1 to 1.5 gallons per hour), therefore causing water to drain out of the unit base.
In order to avoid water accumulation, you may use decorative rocks around the
concrete slab or a basin under the unit. (Please note this is a normal characteristic
of a pool heat pump and not a service or warranty issue.)
A hose may be connected to the supplied spigots fitted prior to final unit installation
to direct the condensate away from the heat pump.
Pool Solar Blanket
A pool solar blanket should be used whenever possible. Blankets minimize heat loss
through evaporation and conserve heat in your pool. Un-blanketed pool can lose 2-3
times more heat than a blanketed pool.
Defrost Cycle
When any of the following conditions occur the electronic control of your unit will
activate a defrost mode until most of the frost from the evaporator has melted.
Condensation of water on the evaporator coil tends to frost up quicker when the
following occur.
1. When atmospheric conditions are as stated above;
2. When the evaporator is dirty;
3. When installation clearances are not respected.
Defrost is activated for between 3 to 20 minutes.

MAINTENANCE OF YOUR POOL HEAT PUMP
Waterco pool heat pumps have been specifically engineered to give you years of
satisfaction and enjoyment in the pool.
Cabinet Cleaning
To clean the plastic and painted surfaces use mild soapy water and a soft clean cloth.
Never use solvents or abrasives.
Cleaning Evaporator
The evaporator at the rear of the unit must be kept clean and un-obstructed in order
for your pool heat pump to have better efficiency and avoid problems which may
void your warranty. The dirt collected in the evaporator can be removed with a gentle
water spray and the use of a soft brush. Be careful not to damage the aluminum fins.
Cleaning drainage holes
The condensate drainage holes in the base of the unit must be kept free of debris.
Blocked drainage holes may cause water to collect in the unit and become stagnant
or, interfere with electrical components and wiring.
Issues caused by blocked drainage holes in the base of the unit are not covered under
warranty.
Units Located In Coastal Locations
Care and maintenance procedures for Waterco Pool Heat Pumps installed in coastal
locations.
Exposure to salt may result in evaporator coil damage shortening the life of the
equipment.
Electroheat ECO-V pool heat pumps are fitted with evaporators treated with
hydrophilic blue fin technology. The advantages are:
The epoxy coating on the coils prevents accumulation of salt, acid, dust and water
deposits which minimises the effects of corrosion.
Hydrophilic blue fin condensers do not allow water droplets to accumulate which can
increase the efficiency of the pool heat pump.
Pool heat pumps located within 1 kilometre from the coast should be given a monthly
rinse with potable water straight from the garden hose connected to the municipal
water system to remove the salt build up on the evaporator coil and exposed metal
surfaces.
