IMPORTANT THINGS TO NOTE

• Ensure you meet the minimum clearances and recommended installation locations as outlined in the manual.
• All heat pump accessories are contained in a plastic bag inside the packaging of your heat pump unit.

PRE-INSTALLATION

1. Position the heater on a level pad in the desired location on the pool water return line (as shown in the example image below).
2. Install the supplied antivibration rubber pads under the feet of the unit.
3. Install the supplied condensation barb to the underside of the unit and direct the condensation to an appropriate drainage point.

AIRFLOW CLEARANCES
Ensure the heater is installed in a well-ventilated area with plenty of fresh air, a minimum gap between walls/fences etc of 1500mm on the sides and 500mm overhead clearance.

PLUMBING INSTALLATION
NOTE: Evo heat pumps standard plumbing fitting size can accept 32mm or 50mm NB PVC pipe for connection to the pool or spa filtration plumbing.

1. Attach the supplied barrel unions to the cold inlet and hot outlet (hand tighten).
2. Use plumbing tape and ensure the ‘O’ ring is in position when sealing.
3. Install a 3-way valve at the cold-water inlet and create a bypass by connecting a “T” piece to the heated line.
4. Make the plumbing connections and brace pipework where necessary.

ELECTRICAL CONNECTION
NOTE: Electrical connection should only be completed by licensed personnel and in accordance with all relevant Australian Standards, applicable laws and local legislations.

1. Remove the external cover to the electrical terminal by removing the screws and the terminal cover panel.
2. Feed the electrical cable in through the conduit nipple and attach the electric supply wires to the applicable Active Neutral and Earth connections located in the electrical terminal.
3. To complete the electrical connection, install electrical conduit, UF cable or other suitable means as specified (as permitted by local electrical authorities) and connect the cable to a dedicated power supply branch circuit equipped with the appropriate size circuit breaker, or time delay fuse protection.

INITIAL STARTUP & COMMISSIONING
NOTE: The water pump must be running and water circulating through the heat pump for the system to operate.

1. Turn on your water filter pump and check for water leaks and verify flow to and from the pool.

2.  Turn on the electrical power supply to the Evo Heat unit

3. Press the ON/OFF button of the controller so that the outlet temperature is displayed on screen, the unit will start within 60 seconds.

4. Press the MODE button to select a mode, continue pressing the button until the small sun icon appears for heating.

5. Go back to the main menu, press the UP or DOWN arrow keys to adjust the target temperature settings. Leave the new temperature idle on the screen for 5 seconds to automatically save the adjustment.

6. After the system has been running for approximately 5 minutes, check the Temperature Differential (TD) of the entering cold water to the exiting heated water.
   a. On the main screen, the larger numbers on the display refer to the outlet water temperature. The smaller numbers below this refer to the inlet water temperature.
   b. Review the inlet and outlet water temperatures and adjust the water flow by opening or closing the 3-way valve installed at the cold-water inlet to achieve a target TD of approximately 2°C (ex. 26°C inlet water and 28°C outlet water).

7. If there is any interruption to water flow (i.e. when the water pump is turned off), the unit will automatically turn off and display an E03 error code – no water flow. This is normal and the system will restart once water flow is reinstated.

INITIAL HEAT UP TIME
Initial heat up times will vary depending on the size of your pool, environmental conditions and the capacity of the system installed. After installation please allow the unit and pool pump to run continuously until the desired pool water temperature is reached (it may take several days for the pool to initially reach the set temperature).
Once the pool water reaches the desired set temperature, the unit will shut off. The unit will automatically restart (provided your pool pump is running) when the pool temperature falls more than 1°C below the desired set temperature.

Installation

5.1 System Installation
Upon receiving the unit, check the packaging for any obvious signs of damage. Inform Evo Heat immediately if there is any evidence of rough handling. When the heater has been removed from the packaging check the refrigerant gauge on the front panel of the unit. The gauge should be showing a pressure of approx. 10 – 20 on the outside red band – any less than this figure means there may be a leak in the refrigerant system, and you should immediately contact your Evo Heat Dealer.
Only the main unit and the water unit in the illustration are provided; the other items are necessary spare parts for the water system that are to be provided by customer or the installer.

When starting for the first time:

1. Open valve and charge water.
2. Make sure that the pump and the water-in pipe have been filled with water.
3. Close the valve and start the unit.

The schematic diagram is for reference only. Please check the water inlet/outlet label on the heat pump while plumbing the unit.
IMPORTANT: Evo Heat heat pumps MUST be connected by a licensed electrician. Under no circumstances should an unlicensed person attempt to install or repair an Evo Heat heat pump themselves. Heater electrical installation undertaken by an unlicensed installer will void the warranty. Correct installation is required to ensure safe and efficient operation of your pool heater.
Before installation it is very important to ensure 5 variables are carefully checked to allow the unit to operate correctly.

• Heater Condition
• Location
• Clearances & Air Flow
• Adequate water flow & plumbing
• Correct electrical connection & supply

5.2 Location of Installation
Evo recommend the heat pump should ONLY be installed in an outdoor location with appropriate ventilation. Installing the heater indoors without adequate ventilation, or in a poorly ventilated enclosed space, will result in very poor performance and can, in extreme cases, damage the heater.
The Evo unit should be installed:

• At least 3.5m away from the water’s edge.
• No greater than 7.5m from the water’s edge (to avoid heat loss from the piping).
• No greater than 5m below the water level of the pool/spa.

Make sure the heat pump is not located where large amounts of water may run- off from a roof into the unit. Sharp sloping roofs without gutters will allow excessive amounts of rainwater mixed with debris from the roof to be forced through the unit. A water deflector may be needed to protect the heat pump.
Ensure the heat pump is not installed close to harsh or corrosive chemicals.
The heat pump should be installed on a flat level surface. If a suitable outdoor location is unavailable please contact Evo Heat for specialist technical advice.
5.3 Airflow Clearances

Ensure the heater is installed in a well-ventilated area with plenty of fresh air, a minimum gap between walls/fences etc of 1500mm on the sides and 500mm overhead clearance. At minimum gap of at least 50mm is required at the rear of the unit.
Leave sufficient space for unobstructed airflow into and out of the heater. Do not locate the heater in an enclosed area, or the discharged cold air will recirculate into the unit and consequently lower the heating efficiency as well as possibly icing up.
If the installation location does not comply with these suggested clearances, contact Evo Heat’s Tech Support to discuss possible solutions.
5.4 Adequate Water Flow
All Evo Heat heat pumps have a factory pre-set internal water flow switch. If there is insufficient water flow the unit will not operate.
It is VITAL that that there is sufficient water flow to the unit. Incorrect water flow can cause a loss of efficiency and possible damage to the unit. Optimal water flow rates are listed within this manual. It is imperative that water flow is kept as close as possible to these flow rates.
Before connecting the heater to the plumbing all piping must be thoroughly flushed to ensure no debris can enter the heater. Failure to remove pipe debris can jam or damage the flow switch and may cause damage to the heater. When cleaning the pool, it is advisable to turn off your heater as restricted water flow may cause the heater to shut down and indicate low water flow fault (E03 error) or high pressure fault (E01 Error).
A Variable speed pump or bypass valve and plumbing MUST be fitted to allow water flow to be adjusted through the heater. Do not direct connect a water pump with higher flow than required to the heat pump.
5.5 Rubber Feet
All Evo Heat units are provided with rubber feet which we highly recommend being installed. The rubber feet help reduce vibration of the unit and provide a space below the heat pump to install the drainage barbs.
5.6 Condensate Drain Barb
Fit the condensate drain barb into the 2 holes under the unit if you need to direct water away from the heater.
If the barb is too stiff, place it in hot water to soften.
5.7 Drainage & Condensation
** During operation, water in the air condenses on the fins of the evaporator. In high humidity, the condensate may be several litres per hour, giving the impression that the unit is leaking. This process is a normal function of heat pumps.
The heater will automatically activate reverse cycle or de-icing mode when required which also increases condensate discharge. This normally occurs at temperatures below 8˚C. The condensate water will discharge through the base of the heater. As an option, a 20mm clear vinyl tube pipe can be connected by hand to the drain on the base of the unit to direct condensate water to an appropriate location.
NOTE
A quick way to verify that the water is condensation is to shut off the unit and keep the pool pump running. If the water stops running out of the base pan, it is condensation. Another method is to test the drain water for chlorine – if the is no chlorine present, then it’s condensation
5.8 Plumbing**
The unit’s exclusive rated flow titanium heat exchanger requires no special plumbing arrangements except bypass (set the flow rate according to the nameplate). The water pressure drop is less than 10kPa at max.

Flow Rate
Since there is no residual heat or flame temperatures the unit does not need copper heat sink piping. PVC pipe can be run straight into the unit.
Location
Connect the unit in the pool pump discharge (return) line downstream of all filter and pool pumps, and upstream of any chlorinators, ozonates or chemical pumps.
Standard models have slip glue fittings which accept 32mm or 50mm PVC pipe for connection to the pool or spa filtration piping. By using a 50NB to 40NB you can plumb 40NB.
Consider adding a quick coupler fitting at the unit’s inlet & outlet to allow easy draining of the unit and to provide easier access should servicing be required.
Ensure pipework connecting to the inlet/outlet unions is appropriately supported, any movement in this pipework can caused the rubber O-ring to pinch and leak.
5.9 Electrical Connection
Always use a qualified Electrician to perform any electrical work. A licensed electrician must read the information before connecting.
Ensure the power cable and circuit breaker are of a suitable size for the heater being installed. Also check that there is adequate voltage and current available at the heater connection to run the unit.
Voltage range should be 220-240 volts for single phase, and 380-415 volts for 3 phase units. Voltage ranges outside these parameters will cause heater damage and void your warranty.

1. Ensure power is disconnected during installation or service.
2.  Always comply with the national and local electrical codes and standards.
3. Ensure the electrical cable size is adequate for heater requirements at the installation location.
4. The heater must be equipped with a circuit breaker and isolation device.
5. The circuit breaker must be installed between the heater and the water circulation pump if the water pump is hard-wired into the heater. Please note recommended circuit breaker sizes make no allowance for a water pump hard wired into the heater.
6. The unit must be well earthed. Remove the front panel to access the electrical connection terminals of the heater. The electrical wiring diagram is affixed to the inside of the front panel or at the back of this manual.

5.10 Initial Start-Up
For the unit to heat the pool or spa, the filter pump MUST be running to circulate water through the heat exchanger.

1. Turn on the filter pump. Check for water leaks and verify there is flow both to and from the pool.
2. Turn of the unit’s electrical power supply, then press the ON/OFF button on the unit to start it.
3. After a few minutes of running, make sure the air leaving the unit is roughly between 5-10°C cooler.
4. With the unit in operation, turn the filter pump off. The unit should then turn off automatically.
5. Allow the unit and the pool pump to run for at least 24 hours a day until the desired temperature is reached. Once this temperature is reached, the unit will periodically slow down and turn off if the temperature is maintained for at least 45 minutes. The unit will automatically restart (as long as the pool pump is running) when the pool temperature drops more than 0.2°C below set temperature.

Maintenance

9.1 F.A.Q

DO I NEED TO GET MY UNIT SERVICED?
It is recommended that you get your Evo Heat unit serviced once a year by your local certified air conditioning or refrigeration technician. If your unit is located in a coastal area, more frequent maintenance may be necessary.

9.2 Advanced

Prior to beginning work on systems containing flammable refrigerants, safety checks are necessary to ensure that the risk of ignition is minimized. For repair to the refrigerating system, the following precautions shall be complied with prior to conducting work on the system. prolonged period of no usage.| All maintenance staff and others working in the local area shall be instructed on the nature of work being carried out. Work in confined spaces shall be avoided. The area around the workspace shall be sectioned off. Ensure that the conditions within the area have been made safe by control of flammable material.
PRESENCE OF FIRE EXTINGUISHER| WORK PROCEDURES
If any hot work is to be conducted on the refrigeration equipment or any associated parts, appropriate fire extinguishing equipment shall be available to hand. Have a dry powder or CO2 fire extinguisher adjacent to the charging| Work shall be undertaken under a controlled procedure to minimize the risk of a flammable gas or vapours being present while the work is being performed.
CHECKING FOR PRESENCE OF REFRIGERANT| VENTILATED AREA
The area shall be checked with an appropriate refrigerant detector prior to and during work, to ensure the technician is aware of potentially flammable atmospheres. Ensure that the leak detection equipment being used is suitable for use with flammable refrigerants, i.e. non-sparking, adequately sealed or intrinsically safe.| Ensure that the area is in the open or that it is adequately ventilated before breaking into the system or conducting any hot work. A degree of ventilation shall continue during the period that the work is carried out. The ventilation should safely disperse any released refrigerant and preferably expel it externally into the atmosphere. prolonged period of no usage.
CABLING| DETECTION OF FLAMMABLE REFRIGERANTS
Check that cabling will not be subject to wear, corrosion, excessive pressure, vibration, sharp edges or any other adverse environmental effects. The check shall also consider the effects of aging or continual vibration from sources such as compressors or fans.| Under no circumstances shall potential sources of ignition be used in the searching for or detection of refrigerant leaks. A halide torch (or any other detector using a naked flame) shall not be used.
REPAIR TO INTRINSICALLY SAFE COMPONENTS| LABELLING
Do not apply any permanent inductive or capacitance loads to the circuit without ensuring that this will not exceed the permissible voltage and current permitted for the equipment in use.
Intrinsically safe components are the only types that can be worked on while live in the presence of a flammable atmosphere.
The test apparatus shall be at the correct rating. Replace components only with parts specified by the manufacturer. Other parts may result in the ignition of refrigerant in the atmosphere from a leak.| Equipment shall be labelled stating that it has been de- commissioned and emptied of refrigerant. The label shall be dated and signed. Ensure that there are labels on the equipment stating the equipment contains flammable refrigerant.
NO IGNITION SOURCES| No person carrying out work in relation to a refrigeration system which involves exposing any pipe work that contains or has contained flammable refrigerant shall use any sources of ignition in such a manner that it may lead to the risk of fire or explosion. All possible ignition sources, including cigarette smoking, should be kept sufficiently far away from the site of installation, repairing, removing and disposal, during which flammable refrigerant can possibly be released to the surrounding space. Prior to work taking place, the area around the equipment is to be surveyed to make sure that there are no flammable hazards or ignition risks. No Smoking signs shall be displayed.
---|---
CHARGING PROCEDURES| In addition to conventional charging procedures, the following requirements shall be followed.
· Ensure that contamination of different refrigerants does not occur when using charging equipment. Hoses or lines shall be as short as possible to minimize the amount of refrigerant contained in them.
·  Cylinders shall be kept upright.
·  Ensure that the refrigeration system is earthed prior to charging the system with refrigerant.
· Label the system when charging is complete (if not already).
·  Extreme care shall be taken not to overfill the refrigeration system.
Prior to recharging the system, it shall be pressure tested with OFN. The system shall be leak tested on completion of charging but prior to commissioning. A follow up leak test shall be carried out prior to leaving the site. The safety wire model is 5*20_5A/250VAC, and must meet the explosion- proof requirements.
CHECKS TO THE REFRIGERATION EQUIPMENT| Where electrical components are being changed, they shall be fit for the purpose and to the correct specification. At all times the manufacturer’s maintenance and service guidelines shall be followed. If in doubt consult the manufacturer’s technical department for assistance.
The following checks shall be applied to installations using flammable refrigerants:
• The charge size is in accordance with the room size within which the refrigerant containing parts are installed;
• The ventilation machinery and outlets are operating adequately and are not obstructed; If an indirect refrigerating circuit is being used, the secondary circuit shall be checked for the presence of refrigerant;
• Marking to the equipment continues to be visible and legible. Markings and signs that are illegible shall be corrected;
• Refrigeration pipe or components are installed in a position where they are unlikely to be exposed to any substance which may corrode refrigerant containing components, unless the components are constructed of materials which are inherently resistant to being corroded or are suitably protected against being so corroded.
---|---
CHECKS TO ELECTRICAL DEVICES| Repair and maintenance to electrical components shall include initial safety checks and component inspection procedures. If a fault exists that could compromise safety, then no electrical supply shall be connected to the circuit until it is satisfactorily dealt with. If the fault cannot be corrected immediately but it is necessary to continue operation, an adequate temporary solution shall be used. This shall be reported to the owner of the equipment, so all parties are advised.| Initial safety checks shall include:
• That capacitors are discharged: this shall be done
in a safe manner to avoid possibility of sparking;
• That there no live electrical components and wiring are exposed while charging, recovering or purging the
system;
• That there is continuity of earth bonding.
REPAIRS TO SEALED COMPONENTS| 1. During repairs to sealed components, all electrical supplies shall be disconnected from the equipment being worked upon prior to any removal of sealed covers, etc. If it is necessary to have an electrical supply to equipment during servicing, then a permanently operating form of leak detection shall be located at the most critical point to warn of a potentially hazardous situation.
2. Particular attention shall be paid to the following to ensure that by working on electrical components, the casing is not altered in such a way that the level of protection is affected. This shall include damage to cables, excessive number of connections, terminals not made to original specification, damage to seals, incorrect fitting of glands, etc.
Ensure that apparatus is mounted securely.
Ensure that seals or sealing materials have not degraded such that they no longer serve the purpose of preventing the ingress of flammable atmospheres. Replacement parts shall be in accordance with the manufacturer’s specifications.
NOTE: The use of silicon sealant may inhibit the effectiveness of some types of leak detection equipment.
Intrinsically safe components do not have to be isolated prior to.
LEAK DETECTION METHODS| The following leak detection methods are deemed acceptable for systems containing flammable refrigerants.
Electronic leak detectors shall be used to detect flammable refrigerants, but the sensitivity may not be adequate, or may need re-calibration. (Detection equipment shall be calibrated in a refrigerant-free area.) Ensure that the detector is not a potential source of ignition and is suitable for the refrigerant used. Leak detection equipment shall be set at a percentage of the LFL of the refrigerant and shall be calibrated to the refrigerant employed and the appropriate percentage of gas (25 % maximum) is confirmed.
Leak detection fluids are suitable for use with most refrigerants but the use of detergents containing chlorine shall be avoided as the chlorine may react with the refrigerant and corrode the copper pipe- work.
If a leak is suspected, all naked flames shall be removed/extinguished.
If a leakage of refrigerant is found which requires brazing, all of the refrigerant shall be recovered from the system, or isolated (by means of shut off valves) in a part of the system remote from the leak.
Oxygen free nitrogen (OFN) shall then be purged through the system both before and during the brazing process.
REMOVAL AND EVACUATION| When breaking into the refrigerant circuit to make repairs or for any other purpose conventional procedures shall be used.
However, it is important that best practice is followed since flammability is a consideration.
The following procedure shall be adhered to:
Remove refrigerant; Purge the circuit with inert gas; Evacuate;
Purge again with inert gas;
Open the circuit by cutting or brazing.| The refrigerant charge shall be recovered into the correct recovery cylinders. The system shall be “flushed” with OFN to render the unit safe. This process may need to be repeated several times.
Compressed air or oxygen shall not be used for this task.
Flushing shall be achieved by breaking the vacuum in the system with OFN and continuing to fill until the working pressure is achieved, then venting to atmosphere, and finally pulling down to a vacuum. This process shall be repeated until no refrigerant is within the system. When the final OFN charge is used, the system shall be vented down to atmospheric pressure to enable work to take place. This operation is absolutely vital if brazing operations on the pipe-work are to take place.
Ensure that the outlet for the vacuum pump is not close to any ignition sources and there is ventilation available. working on them.
---|---|---
RECOVERY| When removing refrigerant from a system, either for servicing or decommissioning, it is recommended good practice that all refrigerants are removed safely.
When transferring refrigerant into cylinders, ensure that only appropriate refrigerant recovery cylinders are employed. Ensure that the correct number of cylinders for holding the total system charge is available. All cylinders to be used are designated for the recovered refrigerant and labelled for that refrigerant (i.e. special cylinders for the recovery of refrigerant). Cylinders shall be complete with pressure relief valve and associated shut- off valves in good working order. Empty recovery cylinders are evacuated and, if possible, cooled before recovery occurs.
The recovery equipment shall be in good working order with a set of instructions concerning the equipment that is at hand and shall be suitable for the recovery of flammable refrigerants. In addition, a set of calibrated weighing scales shall be available and in good working order. Hoses shall be complete with leak- free disconnect couplings and in good condition. Before using the recovery machine, check that it is in satisfactory working order, has been properly maintained and that any associated electrical components are sealed to prevent ignition in the event of a refrigerant release. Consult manufacturer if in doubt.| The recovered refrigerant shall be returned to the refrigerant supplier in the correct recovery cylinder, and the relevant Waste Transfer Note arranged. Do not mix refrigerants in recovery units and especially not in cylinders.
If compressors or compressor oils are to be removed, ensure that they have been evacuated to an acceptable level to make certain that flammable refrigerant does not remain within the lubricant. The evacuation process shall be carried out prior to returning the compressor to the suppliers. Only electric heating to the compressor body shall be employed to accelerate this process. When oil is drained from a system, it shall be carried out safely.
DECOMMISSIONING| Before carrying out this procedure, it is essential that the technician is completely familiar with the equipment and all its detail. It is recommended good practice that all refrigerants are recovered safely.
Prior to the task being carried out, an oil and refrigerant sample shall be taken in case analysis is required prior to re-use of reclaimed refrigerant. It is essential that electrical power is available before the task is commenced.
a) Become familiar with the equipment and its operation.
b) Isolate system electrically.
c) Before attempting the procedure ensure that:
– Mechanical handling equipment is available, if required, for handling refrigerant cylinders;
– All personal protective equipment is available and being used correctly;
– The recovery process is always supervised by a competent person;
– Recovery equipment and cylinders conform to the appropriate standards.
d) Pump down refrigerant system, if possible.
e) If a vacuum is not possible, make a manifold so that refrigerant can be removed from various parts of the system.
f) Make sure that cylinder is situated on the scales before recovery takes place.
g) Start the recovery machine and operate in accordance with manufacturer’s instructions.
h) Do not overfill cylinders. (No more than 80 % volume liquid charge).
i) Do not exceed the maximum working pressure of the cylinder, even temporarily.
j) When the cylinders have been filled correctly and the process completed, make sure that the cylinders and the equipment are removed from site promptly and all isolation valves on the equipment are closed off.
k) Recovered refrigerant shall not be charged into another refrigeration system unless it has been cleaned and checked.
