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 17kW - heat / cool with automatic evaporator deicing electroheat eCO-V 21kW - heat / cool with automatic evaporator deicing electroheat eCO-V 25kW - heat / cool with automatic 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. 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. 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 supplied drainage spigots to the underside 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) fitted under each foot. each foot may then be bolted down to the concrete slab (supplied by other).

Pool Heat Pump I 06

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.

No obstruction within 4 metres to allow cold air dispersal clearance to rear minimum 60cm

Clearance for service access 60cm

Figure 1

Clearance to side minimum 60cm

07 I Pool Heat Pump

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 between 110 - 195 litres per minute.

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.

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.

09 I Pool Heat Pump

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.

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 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.

Remote Control Connections

1. Switch off power to heat pump at main circuit breaker panel/isolator.

2. unbolt and remove the front access panel.

3. Open control box cover.

4. To connect a 2-Wire Control such as Waterco Aquamaster™: ii) locate the main printed circuit board and cable connected to terminal IN1

(overload protector).

ii) Cut the loop cable in terminal IN1 and connect the two ends of the cut cable separately to the two ends of the incoming external controller cable and make electrically safe. use 1mm 2 minimum cable size with a minimum 1.2mm thick insulation rated for a temperature of at least 105°C / 221°F.

5. Close control box cover.

6. re-install the access panel. To control heaters that are operated in parallel, connect wiring at same locations on heater control. It is imperative that each control circuit is isolated from the other control circuits; to avoid current flow from one heater to another through the control circuits.

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.

Waterco recommend atmospheric conditions as well as the pool water temperature should not be below the minimum operating temperatures as stated below in order to obtain efficiency and avoid codes from appearing on the electronic control temperature display ; these codes are not generally an issue with the pool heat pump at these conditions and is not covered by the warranty.

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.

Model electroheat eCO-V

Atmospheric conditions must be above

0°C / 32°F

Pool water temperature must be above

10°C / 50°F

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.

15 I Pool Heat Pump

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 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.

Pool Heat Pump I 20

Winterising Procedure

!

If the pool heat pump is stored in a place where the temperature drops below the freezing point of 0˚C / 32°F; it is mandatory that the water accumulated in the pool heat pump be drained completely before freezing weather prevails. Improper winterizing may damage the pool heat pump and will void the warranty.

• Turn the pool heat pump “OFF”.

• Turn the pool heat pump breaker “OFF”.

• The water piping MUST be disconnected to drain the pool heat pump’s heat exchanger in preparation for winter.

• Once the piping is disconnected, the pool heat pump’s heat exchanger MUST be emptied; the use of a water vacuum cleaner is strongly recommended or if you do not have this tool you may tilt the unit (75˚) until all the water is out.

• It is recommended that pool heat pump’s heat exchanger is rinsed out with a gentle water spray at the inlet and outlet water connections of the pool heat pump and then drain the heat exchanger again.

• With the help of 2 pool return winter plugs, block the water Inlet and Outlet connections to prevent access by vermin.

• Clean the drainage holes located at the bottom of the base of the unit.

• unit may be covered for the winter.

• It is also possible to fill the heat exchanger with pool anti-freeze, but ensure that the antifreeze contains an elevated pH to prevent corrosion. This is optional and requires appropriate hardware.

21 I Pool Heat Pump

GENERAL SAFETY INSTRUCTIONS

DO NOT DEPRIVE YOUR POOL HEAT PUMP OF WATER FLOW FOR MORE THAN 24

HOURS WITHOUT DRAINING IT. Make sure you leave the bypass valves as shown in Figure 1.

At the end of each season, when the pool heat pump is no longer in use, and proper pool water chemistry is not maintained, it should be disconnected from the water line and drained to prevent any possible corrosion or damage to the pool heat pump. refer to Figure 1 below or winterising procedure (page 24).

TROUBLESHOOTING

Please ensure the unit and any related equipment is installed in accordance with the installation manual. If not, the Waterco warranty will not apply and the customer may be liable for service call charges.

Nothing Is Working And The Electronic Control Does Not

Operate

1. ensure the circuit-breaker has not tripped and/or the fuses have not blown;

**Take note that only an electrician can verify if the circuit breaker is defective; if this is the case, repairs will not be covered under the warranty.

2. For three phase models, this situation could occur when phases are not in the appropriate order. The green led light on the front panel will not light up.

Please have a qualified electrician swap over two of the incoming phase wires.

Nothing Is Working But The Electronic Control

Temperature Displays Digits Or A Code

1. Identify the analyser code that the electronic control displays and refer to the

Service Analyser codes section;

2. If the electronic control displays digits, make sure that the electronic control is programmed correctly, refer to the Operation of your pool heat pump and reprogram if necessary.

**Note that this situation could occur when the electrical voltage is not respected as stated on the pool heat pump name plate. This situation is not covered by the manufacturer warranty.

Fan Doesn’t Work (the fan blades are not moving)

1. IMPOrTANT: For safety, switch OFF the circuit-breaker.

2. Try to rotate the fan blades of the fan with a rod to see if the motor is jammed or seized

3. If the fan blades do not turn freely leave the unit switched OFF and call for service;

4. If the fan blades turn freely switch ON the circuit breaker and the pool heat pump again.

** Note that your fan motor may have an electrical fault if the blades turn freely when the unit is switched OFF and does not start when the unit is switched ON.

23 I Pool Heat Pump

Fan Blades Turn, But Compressor Is Not Functioning

The pool heat pump has a built in delay timer which prevents the compressor from starting immediately. The delay can be 3 to 5 minutes in duration after the fan blades have turned. Furthermore if the unit is in defrost mode the compressor will not start for 3 to 20 minutes.

1. Check that air being discharged from the fan blades is colder than the ambient air.

If the air being discharged by the fan blades is colder, it means that the compressor is functioning correctly.

2. Turn off the pool heat pump then immediately turn it back on;

3. As soon as the fan blades start turning, wait a minimum of 3-5 minutes. The compressor should start up after this time and you will be able to identify a different sound made by the compressor when it starts;

4. If the compressor is functioning, but shuts off immediately, consult the following section “Compressor Starts and Stops”.

5. If the problem persists, call your local Waterco office for assistance.

Compressor Starts And Stops

1. Check that the unit has been installed correctly (refer to installation procedures).

2. Check that the water inlet and outlet of the unit have not been connected incorrectly.

There Is Water Around The Pool Heat Pump

It is a normal occurrence for water condensation, to be seen running from the unit base. There will be on average 1 to 1.5 gallons (4 to 6 litres) of condensed water per hour being discharged from the unit base. In order to avoid water accumulation, you may use decorative rocks around the concrete slab or a basin under the unit. be sure that clearances around the unit are respected.

To test the unit and confirm you have no pool water leaking from the unit perform the following test which is best performed early in the morning and continuing for the whole day:

1. Turn off the pool heat pump from the circuit breaker and the pool pump.

2. Open the bypass valve. (refer to drawing on page 5)

3. Close the IN and OUT water valves on the unit.

4. restart the pool pump. The pool heat pump must remain OFF.

5. When all of the water around the base of the pool heat pump has dried, open the water IN and water OUT valves on the pool heat pump.

6. Close the bypass valve to allow full water flow through the pool heat pump.

If water is now seen running from the outside of the pool heat pump or inside the pool heat pump after a short period of time you should call for service. If no water is seen after a short period of time it would be assumed the water was condensation which is normal.

Pool Heat Pump I 24

Pool Heat Pump Has Ice Formed On The Evaporator Coil

1. IMPORTANT: For safety, switch OFF the circuit-breaker.

2. Allow the ice to melt and then inspect the evaporator to ensure it is free of debris and leaves.

3. If the evaporator is dusty or dirty, clean it with a light spray of water and allow it to dry (do not use high pressure it may damage the evaporator fins).

4. When the unit is dry, you may switch it back ON from the circuit breaker.

5. ensure that the clearances around the unit are respected.

6. When the unit has been switched ON ensure the fan motor is working (fan blades will be turning) while the compressor is operating.

7. If the fan blade does not turn and the compressor is functioning; notify customer service.

**If the pool heat pump requires service, the owner of the pool heat pump will need to ensure the unit has been switched OFF to allow any ice to melt prior to any technician attending.

Pool Heat Pump Is Functioning, But Does Not Reach The

Desired Temperature Setting

Improper installation may cause this situation and will need to be corrected by the owner.

1. ensure the by-pass valves are in the correct positions to ensure sufficient water flow, insufficient water flow will cause the compressor to shut off early.

2. If you have installed a timer or the pool heat pump is equipped with an integrated timer, be sure it is programmed to allow the pool pump to work for sufficient time in order to reach the programmed temperature.

3. ensure the evaporator is cleaned regularly with a light spray of water and allowed to dry before re-starting the pool heat pump to avoid premature ice build up on the evaporator.

4. Waterco recommend the use of a solar cover to retain heat in pool water. Pools without covers lose 2 to 3 times more heat than pools with solar covers.

5. Make sure the electronic control of your pool heat pump has been programmed correctly;during this test the pool heat pump and water pump must be working continuously (eg; the desired water temperature must be set correctly).

6. If the unit continually fails to reach the desired water temperature, we suggest completing the following analysis chart and forwarding it to Waterco in order to avoid unnecessary service fees.

25 I Pool Heat Pump

Circuit Breaker Trips

If you have purchased a remote control (or other equipment), ensure the equipment is correctly installed. If an operational issue originates from incorrect operation or installation of this equipment, Waterco’s warranty will not apply and you will have to pay the cost of the service call.

1. The amperage of the circuit breaker ANd the electrical wiring must be as the instructions on the pool heat pump name plate, otherwise notify your installer or electrician to correct this problem, as this is not covered under the warranty.

2. If the circuit breaker and electrical wiring are as stated, make sure the drains, located on each side of the base of the pool heat pump are not obstructed.

The Pool Heat Pump Is Noisy

1. Check the pool heat pump is level and on a solid base to prevent any vibrations issues.

2. ensure the noise is coming from the pool heat pump, not from other equipment which will not be covered by the warranty (for example: noise coming from the bypass valve, pool pump, etc);

3. An improper installation may cause this situation it will need to be corrected by the owner.

The Temperature Shown On Pool Heat Pump Is Not The

Same That Is Shown By The Pool Thermometer

It is possible to have a temperature variation between the temperature shown on the electronic control temperature display of the pool heat pump and a pool thermometer which may be read from different locations.

- Check that there are no leaks on the pool plumbing (there should be no air leaks in the pipework);
