5.3 – Hydraulic connections

· A new pressure-relief valve (not included) must be installed and set to 6 bars on the domestic cold water supply of the appliance. The use of a membrane valve is recommended. This valve must conform to all local and national standards.
·The pressure-relief valve should be installed as close as possible to the appliance’s cold water inlet and the water flow should never be hampered by any accessory (valve, pressure-reducer, etc.).
· The pressure-relief valve drainage outlet should be sized according to building regulations and standards and must never be obstructed. It should be connected to a vertically draining pipe, using a funnel which allows an open space of at least 20mm and which is at least equal in diameter to the appliance’s piping connection.
· The pressure-relief valve drainage outlet must be installed in a frost-free place and in a downward-sloping position. · If the pressure of the domestic cold water supply is higher than 5 bars, a pressure-reducer should be installed above the pressure-relief valve
near the starting point of the installation (a pressure of 3-4 bars is recommended). · It is advised to fit a shut-off valve above the pressure- relief valve. · For installations equipped with:
– small diameter piping – ceramic plate valves A domestic expansion vessel, or anti-hammer valves which are adapted to the installation should be installed as close as possible to the shut-off valve.

· The following materials should be used for the domestic hot water circuit: – copper – stainless steel – brass – plastic materials
Consequently, the appliance should always be connected to copper domestic hot water pipes with a cast-iron or steel link, or with dielectric
fittings (included) to avoid an iron/copper galvanic bridge.
· Flush the supply line piping before connecting the appliance to the domestic installation so as not to introduce any particles, metallic or
otherwise, into the appliance.
· Respect all standards in effect in the country of use, notably sanitation regulations and pressure safety regulations. · The maximum domestic hot water temperature at distribution points should never exceed 50oC for the toilets, and 60oC for other uses.
Adequate thermostatic mixing valves should be installed to any avoid risk of burns.
· In regions where water contains very high levels of limescale (TH>20°F), it is recommended to treat the water with a softener. Softened water
should conform to the criteria defined by the country of use’s regulations.
· Not respecting the conditions below, see DTU-60-1, will render the warranty on the tank null and void (values given are for water at a
temperature of 20°C).

5.4 – Condensates drainage
The cooling of the air circulating in the evaporator can lead to the formation of condensate, the quantity of which varies according to the level of humidity in the air. Condensate must be evacuated via a drain pipe at the rear of the appliance to a waste water drain. To ensure correct drainage, the following points must be observed:
· Drainage must be via a siphon (the hose must not be used as a siphon) to the waste water system ; · Fill the siphon with water ; · The drain pipe must be immersed in the water in the siphon ; · A minimum 3° slope must be maintained ; · It is forbidden to bend the hose ; · Do not connect to a nipple.

The siphon is essential, as if it is connected directly to the waste water, rising sewage can damage the appliance’s refrigeration circuit!

The condensate plug, supplied in the documentation packet, is fitted to the overflow of the condensate discharge tee.

It is compulsory: · On a ducted installation, during the building air- tightness test, to prevent air leaks. · For installations with a long duct or in collective ducts, coupled with an anti-depression siphon, it prevents noise caused by water being sucked into the siphon.
For an unducted installation or one with a short length of duct, it is not necessary to use the plug.

5.5 – Electrical connections
Do not connect the Domestic hot water heat pump to a power line that has been previously used for a boiler with an automatic peak/off-peak time control. The domestic hot water heat pump must be connected to a power supply at all times and the peak/offpeak time control must be managed using the programming on the control panel, or through use of an independent cable. Grounding is mandatory.
Power supply: 230V single phase + ground
The power supply should comply with the regulations in effect in the country of installation, as well as the NFC 15-100 standard. A means of disconnection which ensures total power cut-off in Category III conditions should be installed in the fixed piping in compliance with the installation regulations. Protect the appliance with:
· a 10A (D-curve) all-pole circuit-breaker with a minimum 3mm contact opening.
· A protective 10A (D-curve) circuit-breaker with a 30mA differential.
If the power supply cable is damaged it must be replaced by the manufacturer, their customer service technicians, or by a qualified professional so as to avoid any risk of injury or danger.
5.5.1 – External control
Only an external «dry contact», voltagefree connection is authorised. Otherwise, there is a risk of damage to the electronic circuit board.

It is not advised to operate the Domestic hot water heat pump during off-peak hours to optimise performance.
It is not necessary to connect the electricity meter’s timer switch to program the Domestic hot water heat pump for peak/off-peak time operation. The appliance’s control panel can be used to program time slots for the Domestic hot water heat pump or for the electrical back-up to run (see § «Programming» for daily programming options).

5.5.1.1 – Peak/off-peak hours contact
It is also possible to connect the electricity meter dry-contact to the Domestic hot water heat pump without using programming.

– Switch open – Switch off

= Load shedding = Normal operation

The load shedding level can be selected and programmed for the appliance (see § «Load shedding»).

By default, the electrical back-up does not run during peak hours.

· Remove the protective casing. · Remove the black cover from the electronics board. · Pass a 0.75mm² 2-wire cable with metal tips through a cable gland
at the back of the appliance and bring the end of the cable around to the electronics board. The other end of the cable should be connected to the timer switch. · Insert the 2-wire cable through a grommet from the electronics box. · Connect the 2-wire cable to «Input 1» indicated on the electronics board, after removing the existing red bridge.
5.5.1.2 – Controlled ventilation
The domestic hot water heat pump can be used to continuously ventilate a room even if the heating cycle is complete. To stop the fan from operating, connect a timer on a moisture sensor. Use the same procedure as for the timer switch, but connect the 2-wire cable to «Input 2» on the electronics board.
– Switch open = The fan will not operate – Switch closed = Th fan will operate
· Set the regulator to «External control ventilation mode» : f a n mode 3
5.5.1.3 – Connection to electricity provider
To prevent the electrical back-up from running during peak hours, connect the dry contact originating from the electricity counter, to terminal 1.
– Switch open = Back-up not allowed to run – Switch closed = Back-up allowed to run By choosing load shedding level 0 or 1 (see § «Load shedding»), the electrical back-up alone is prevented from running (load shedding =1) both the heat pump and the electrical back-up are prevented from running (load shedding = 0). Only a external connection, using a voltage-free «dry contact» is authorised (otherwise there is risk of damaging the electronic circuit board). · Pass a 0.75mm² 2-wire cable with metal tips through a cable gland at the back of the appliance and bring the end of the cable around to the electronics board. The other end of the cable should be connected to the timer switch. · Insert the 2-wire cable through a grommet from the electronics box. · Connect the 2-wire cable to «Input 1» indicated on the electronics board, after removing the existing red bridge.

5.5.1.4 – Connection to the PV function
This function enables the appliance to operate in auto-production mode, which means that it will use the energy produced by the PV function to supply the heat pump as well as the electrical back-up, and to heat the water in the tank. The connection is made between the energy manager electrical box (not supplied) and connectors 1 and 2 on the electronics board. · Remove the protective casing. · Remove the black cover from the electronics board. · Connect the PV function cable to connector 1 on the electronics board. · If the PV function regulator has 2 control contacts, connect them to connectors 1 and 2 on the electronics board § « Electrical wiring diagram» in
the appendix. · Terminal n° 1 : a low level of electrical energy is produced by the PV function. · Terminal n° 2 : a high level of electrical energy is produced by the PV function.
CAUTION: Connectors 1 and 2 are for DRY CONTACTS ONLY. They must NEVER be connected to 230V.

SET-UP AND USE

Deterioration risk : the hot water tank must be filled with water before it is switched on or connected to a power supply.
· Leave the appliance unplugged. · Open the hot water outlet which is located at the highest point
of the appliance. · Open the cold water inlet on the pressure-relief valve. · Fill the tank until water is coming out of the highest water outlet. · Close the hot water outlet.
Before turning the appliance on, ensure that the entire circuit is watertight.
The domestic hot water heat pump operates primarily with
the heat pump as long as the air intake temperature remains in the authorised range of -7°C to +35°C to provide a water temperature of up to 55°C. Outside of this range, the electrical back-up ensures the heating of domestic hot water.
The temperature of the domestic hot water provided by the Heat Pump is adjustable up to 55oC.
In the case of significant domestic hot water usage, the domestic hot water heat pump has a T°C mini function which increases the heating power once there is less than 1/3 of the volume of the tank remaining at 38°C (see § «T°C MINI -minimum temperature-»). A different parameter allows to activate the back-up if the heating time is too long (see § «max time»).
If more domestic hot water is required from time to time, the
domestic hot water heat pump has a «BOOST » function
(activated by the user) which ensures that the water heats to the desired temperature (for example: 50°C) quickly with the help of the heat pump and the electrical back-up. This function is deactivated as soon as the desired temperature is reached (for example : 50°C), (end of heating cycle). Periodically check that there are no alerts (in case of an alert, refer to § «Error message codes»).

area.

  1. Do not smoke

7.1 – Water circuit / Condensates drainage
Check that condensates are draining properly: – Remove the upper cover. – Check that the drainage outlet is not blocked. – Clean the condensates recovery trough, where deposits from the air intake may have gathered. – Clean the flexible drainage hose.
The pressure limiting device must be operated regularly to eliminate limescale and to check for blockages.
Check that all hydraulic connections on the domestic hot water heat pump are watertight.

The R290 refrigerant in the heat pump circuit poses no risk to the environment, but it is flammable.
The R290 refrigerant is odourless, do not damage the pipes in the refrigerant
circuit,
do not handle a flame or any other flammable source on the inside of the appliance.
If the refrigerant is leaking, unplug the appliance, air out the room, and contact customer service.
Do not use any mechanical means to speed up defrosting.
Do not pierce or burn the appliance: in case of intervention on the refrigerant circuit, the refrigerant must be recovered.
The refrigerant circuit containing flammable refrigerant fluid complies with national gas regulations.
…/…

To access the heat pump and the electrical connections you will first need to partially dismantle the air duct, starting with the Ø80 inside pipe and then the insulated elbow:
1- Partially unscrew (or remove) the 2 screws which fix the shell to the lower part of the appliance.
2- Turn the hood slightly to the right to free the notches.
3- Lift the hood and shell up together vertically.

32

– INSTALLATION DOMESTIC HOT WATER HEAT PUMP 100L & 150L AIR MANUAL –

7.2 – Air intake circuit
The only maintenance work needed on the air intake circuit is to clean the evaporator (at least once per year and dependent on the quality of air intake).
If using air filters check if they are clean regularly. Clean and replace if necessary.
The fan blades are sharp-edged and may cause injury; take care not to damage or deform them.
7.3 – Electrical maintenance
It is mandatory to periodically inspect the cleanliness and the absence of dust deposits on the electronic circuit board and the electrical connection terminals:
· of the compressor; · of the electrical resistance; · of the different condensers.
Verify the correct tightness of all lugs. Adapt the frequency of inspection to the air quality. In a dusty environment more frequent maintenance and inspection is necessary, at minimum once per year. · Check that the wiring is not subject to wear, corrosion, excessive
pressure, vibration, contact with sharp edges or any other adverse effects due to its environment. · Maintenance must also take into account the effects of long-term continuous vibration from components such as the compressor and fan.
Neglecting to clean the circuit board and other electronic components in a dusty environment can lead to a risk of overheating and ignition.
7.4 – Drainage
When draining the tank, ensure that there is a sufficient air intake at a high point of the tank so as to avoid any depressions in the tank. Materials and products to avoid:
– brushes with steel bristles and steel wool pads – scouring powder – all bleach based or chloride products

  1. Switch off the power supply.
  2. Shut off the cold water inlet valve on the safety group and ensure there is an air intake valve on a high point of the appliance.
  3. Open the hot water valves.
  4. Set the safety group to the drainage position.
    7.5 – Modification
    Any modification of the appliance is prohibited. Any replacement of components must be done by a professional with original parts from the manufacturer.

7.6 – Decommissioning
7.6.1 – Leak detection
In the event of a prolonged absence with the power supply to the housing and the product disconnected, ask a qualified professional to drain the product or protect it from freezing. Under no circumstances should potential ignition sources be used for the detection or detection of refrigerant leaks. A halogen flare (or other detector using an open flame) shall not be used.
· Electronic leak detectors may be used to detect refrigerant leaks, but for flammable refrigerants, sensitivity may not be adequate or may require recalibration.
· Ensure that the detector is not a potential ignition source and is suitable for the refrigerant used. Leak detection equipment must be set to a percentage of the lower flammability limit of the refrigerant and must be calibrated for the refrigerant used. The value of 25% of the lower flammable limit is used as the maximum.
· Liquid leak detectors are also suitable for use with most refrigerants but the use of chlorine-containing detergents should be avoided as chlorine can react with the refrigerant and corrode copper from the piping.
· If a leak is suspected, all open flames must be suppressed / extinguished.
7.6.2 – Removal and evacuation
· When opening the refrigeration circuit to perform repairs – or for any other purpose – conventional procedures must be used.
· For flammable refrigerants, it is important to use best practice as flammability must be considered.
· The following procedure must be followed :
– Remove the refrigerant ;
– Purge the circuit with inert gas ;
– Evacuate to the atmosphere;
– Purge with inert gas ;
– Open the circuit by cutting or brazing.
· Refrigerant must be recovered in a suitable recovery bottle.
· The system must be purged with nitrogen without oxygen.
· This process may need to be repeated several times. Compressed air or oxygen should not be used to purge refrigerant systems.
· The purge of refrigerants must be performed by breaking the vacuum in the system with nitrogen without oxygen: By filling up until the working pressure is reached, an evacuation to the atmosphere, and finally by vacuum pulling.
· This process must be repeated until there is no more refrigerant in the circuit.
· When the last oxygen-free nitrogen charge is used, the circuit must be brought to atmospheric pressure to allow intervention.
· Ensure that the vacuum pump outlet is not near potential ignition sources and that ventilation is available.

– INSTALLATION DOMESTIC HOT WATER HEAT PUMP 100L & 150L AIR MANUAL –

33

7.6.3 – Charging process
· Ensure that contamination of different refrigerants does not occur when using charging equipment. Hoses or lines should be as short as possible to minimize the amount of refrigerant they contain.
· Cylinders must be held in an appropriate position according to instructions.
· Make sure the refrigeration system is grounded before charging the system with refrigerant.
· Label the system when the load is complete (if not already done).
· Extreme precautions must be taken to not overload the refrigeration system.
· Before recharging the system, it must be pressure tested with the appropriate purge gas.
· The system must undergo a leak test at the end of the load but before commissioning. Another follow-up leak test must be performed before leaving the site.
7.6.4 – Decommissioning
· Before performing this procedure, it is essential that the technician knows the product and all its specificities.
· It is recommended to use best practices to ensure that all refrigerants are safely recovered. Before the task is performed, an oil and refrigerant sample must be taken in case an analysis is required before recycling the recovered refrigerant. It is essential that a power supply is available before the intervention begins.
a) Familiarize yourself with the product and how it works
b) Electrically isolate the system.
c) Before attempting the procedure, ensure that:
– mechanical handling equipment is diponible, if necessary, for the handling of refrigerant cylinders ;
– all personal protective equipment is available and used correctly ;
– the recovery process is being overridden at all times by a competent person.
– recovery equipment and cylinders comply with appropriate standards.
d) Perform a «pump down» on the appliance where possible.
e) If it is not possible to vacuum, make a manifold so that the refrigerant can be removed from various parts of the system.
f ) Make sure the recovery bottle is on the scale before the start of fluid recovery.
g) Start the recovery group and operate it according to the instructions.
h) Do not overfill bottles (no more than 80% in volume of liquid charge).
i) Do not exceed the maximum operating pressure of the cylinder, even temporarily.
j) Once the cylinders have been filled correctly and the process completed, ensure that the cylinders and product are removed from the site quickly and that all isolation valves on the product(s) are closed.
k) Refrigerant must not be loaded into another refrigeration system unless cleaned and verified.

7.6.5 – Recovery
When transferring refrigerant into the recovery bottles, ensure that only the appropriate bottles are used. Make sure you have enough bottles to recover the entire system load. All cylinders used are dedicated to the refrigerant recovered and labeled for it (i.e., special cylinders for refrigerant recovery). Cylinders must be complete with pressure relief valve, associated shut-off valves and in good working condition. Empty recovery cylinders are evacuated and, if possible, cooled prior to recovery.
· Recovery equipment must be in good working order with all instructions at hand and must be suitable for recovery of all refrigerants including, where applicable, flammable refrigerants. In addition, a set of calibrated scales must be available and in good working order.
· Hoses must be complete with leak-free disconnects and in good condition. Before using the recovery machine, verify that it is in good working order, has been properly maintained and that all associated electrical components are sealed to prevent ignition in the event of a refrigerant leak. Consult the manufacturer if in doubt.
· The recovered refrigerant must be returned to the supplier in the appropriate recovery bottle and the transfer note filled in correctly. Do not mix refrigerants in recovery units and especially not in recovery bottles.
· If compressors or compressor oils need to be replaced, make sure they have been vacuum pulled to an acceptable level to ensure they are not left in the flammable refrigerant lubricant. Vacuum pulling must be done before the compressor is returned to the supplier. Only electric heating of the compressor body should be used to accelerate this process. When oil is drained from a system, it must be done safely.
7.6.6 – Recycling and Disposal
· The product must be labelled indicating that it has been taken out of service and emptied of the refrigerant.
· The label must be dated and signed.
· Ensure that there are labels on the product indicating that it contains a flammable refrigerant.
Entrust the disposal of the packaging to the installer who installed the product.
The above symbol requires: – Do not dispose of the product with the household waste. – Dispose of the product at a collection point for used electrical and electronic equipment.
