fig. 10 - Drilling

fig. 11 - Wall mounting

5.3 Aeraulic connections

In addition to the spaces indicated in 5.1, the heat pumprequires adequate air ventilation.

Create a dedicated air channel as indicated in fig. 12.

fig. 12 - Example of air outlet connection

Install each air channel, making sure:

• It does not weigh down on the equipment.
• It allows maintenance operations.
• It is adequately protected to prevent the accidental intrusion of materials inside the equipment.
• The connection to the outside must be done with suitable, non-flammable piping.
• The total equivalent length of the extraction pipes plus the delivery, including grilles, must not exceed 12m .

The table gives the characteristic data of commercial ducting components with reference to nominal air flows and diameters 125mm

Data	Smooth straight pipe	Smooth 90° curve	Grille UM
Type
Effective length	1\m
Equivalent length	122m

During operation, the heat pump tends to lower the room temperature if the air ducting is not to the outside.

A suitable protection grille must be installed at the air extraction pipe to the outside to prevent any foreign bodies from entering inside the equipment. To ensure maximum product performance, the grille must be selected from those with low pressure loss.

To avoid the formation of condensation water: insulate the air extraction pipes and the ducted air cover connections with a steam-tight thermal covering of adequate thickness.

Install silencers if deemed necessary to prevent noise due to the flow. Equip the pipes, wall outlets and connections to the heat pump with vibration-damping systems.

ATTENTION!: The simultaneous operation of an open-chamber hearth (e.g. open fireplace) and the heat pump causes a dangerous negative pressure in the room. The negative pressure can cause the return of exhaust gases into the room.

Do not operate the heat pump together with an open-chamber hearth.

Only use sealed-chamber hearths (approved) with separate combustion air supply.

Keep tight and sealed the doors of boiler rooms that do not have the inflow of combustion air in common with living areas.

5.4 Securing and connections of EGEA

The product must be installed on a stable, flat floor that is not subject to vibrations.

5.5 Plumbing connections

6.6 Additional functions

6.6.1 Anti-Legionella

The display shows the symbol

Every two weeks, at the set time, a water heating cycle is carried out by means of the heating element inside the tank, up to the anti-legionella temperature, maintaining it for the set time.

If, on reaching the anti-legionella temperature, the cycle is not performed correctly within 10 hours, it is stopped and will be run again after 2 weeks.

If the request for the anti-legionella function occurs with HOLI-DAY mode selected, the anti-legionella cycle will be carried out immediately when the unit is reactivated after the set days of absence.

Anti-legionella parameters Range Default
Anti-legionella temperature set-point (P3) 50÷75°C 75°C
Anti-legionella cycle duration (P4) 0÷90 min 30 min
Anti-legionella cycle activation time (P29) 0÷23 h 23 h

6.6.2 Defrost function

The display shows the symbol

This equipment has an automatic evaporator defrost function which is activated, when the operating conditions require it, during heat pump operation.

Defrosting occurs through the injection of hot gas into the evaporator, allowing it to be rapidly defrosted.

During defrosting, the heating element, which the equipment is provided with, is switched off unless otherwise set via the installer menu (parameter P6).

The max. duration of defrosting is 8 minutes.

6.6.2.1 Frost protection

The display shows the symbol

This protection prevents the water temperature inside the tank from reaching values close to zero.

With the equipment in standby mode, when the water temperature inside the tank is below or equal to 5^ (parameter configurable via installer menu), the frost protection function activates, which switches on the heating element until 12^ is reached (parameter configurable via installer menu).

8.2 Heating element safety thermostat reset

This equipment has a manual-reset safety thermostat connected in series with the heating element immersed in water, which interrupts the power supply in case of overtemperature inside the tank.

If necessary, proceed as follows to reset the thermostat (reserved for qualified technical personnel):

• Unplug the product.
• Remove the bottom cover by first undoing the locking screws (fig. 40).
• Manually reset the tripped safety thermostat (fig. 41). In case of tripping, the central pin of the thermostat comes out by

about 2mm

• Refit the previously removed bottom cover.

fig. 41 - Safety thermostat reset

Any maintenance operation must be carried out by qualified personnel according that prescribed in the chapter 10 of this manual.

ATTENTION!: Intervention of the safety thermostat can be caused by a fault linked to the control board or by no water inside the tank.

ATTENTION!: Carrying out repair work on parts with safety function compromises safe operation of the equipment. Replace faulty parts with original spare parts only.

NB!: Intervention of the thermostat excludes operation of the heating element but not the heat pump system within the permitted operating limits.

ATTENTION! If the operator is unable to eliminate the fault, switch off the equipment and contact the Technical Assistance Service, communicating the model of the product purchased.

9. MAINTENANCE

ATTENTION!: Any repairs to the equipment must be carried out by qualified personnel. Improper repairs can put the user in serious danger. If your equipment needs any repair, contact the service center.

ATTENTION! Before undertaking any maintenance operation make sure the equipment is not and cannot accidentally be electrically powered. Therefore, disconnect the power at every maintenance or cleaning operation.

9.1 Sacrificial anode check/replacement

The magnesium (Mg) anode, also called "sacrificial" anode, prevents any eddy currents generated inside the boiler from triggering surface corrosion processes.

In fact, magnesium is a weakly charged metal compared to the material of which the inside of the boiler is coated, therefore it attracts first the negative charges that form with the heating of water, consuming itself. The anode therefore "sacrifices" itself by corroding itself instead of the tank. The boiler has two anodes, one fitted in the lower part of the tank and one fitted in the upper part of the tank (area more subject to corrosion).

The integrity of the Mg anodes must be checked at least every two years (preferably once a year). The operation must be performed by qualified personnel.

Before doing the check:

• Close the cold water inlet.
• Proceed with emptying the boiler (see par. "9.2 Boiler emptying").
• Remove the bottom cover 1.
• Disconnect the heating element safety thermostat electrical connection from the power board and remove the water NTC probes from the dedicated pipe in the element flange.
• Remove the flange by unscrewing the bolts 3. The corrosion of the anode 4 can then be checked; if it affects more than 2/3 of the anode surface, proceed with replacement.

fig. 42
fig. 43

The flange has a special gasket which must be replaced if the anode is checked or replaced.

9.2 Boiler emptying

If not in use, especially in case of low temperatures, it is advisable to drain the water inside the boiler. For the equipment in question, just open the drain cock as per the example hydraulic connections chap. "Plumbing connections" on page 81 (see fig. 15).

NB! In case of low temperatures, remember to empty the system to avoid freezing.

Any maintenance operation must be carried out by qualified personnel according that prescribed in the chapter 10 of this manual.

10. MAINTENANCE OPERATIONS ACCORDING TO IEC EN 60335-2-40_A1_2007 (ANNEX DD)

ATTENTION

Do not use any means to accelerate the defrosting or cleaning process, other than those recommended by the manufacturer.

The unit must be placed in a room that does not have continuous ignition sources (e.g. naked flames, a gas appliance or electric heater in operation).

Do not pierce or burn.

Remember that refrigerant fluids may be odorless.

The unit must be placed, installed and operated in a room larger than 10m^2 with ceiling at least 2 meters high, the air inlet and outlet must be ducted to the outside according to that given in par. 5.3 of this manual.

The overall volume of the installation compartment must be greater than 20m^3

The product is supplied with an R290 refrigerant charge of 150g; any recharging operations can only be performed at the manufacturer's production site.

Any maintenance operation must be performed by qualified personnel in accordance with the instructions in this manual.

FIRE RISK

The product must be installed in a room equipped with adequate air change to prevent the risk of fire in case of a refrigerant gas leak.

In the above is not possible, the installer must carry out the necessary works to ensure that no refrigerant gas stagnation occurs.

Periodically check that there are no obstructions in the openings that ensure the change of air inside the installation room.

The product must not be installed in a compartment where there are naked flames, e.g. open-chamber gas boilers, wood stoves, electric stoves and in general any other possible source of ignition.

Smoking near or inside the installation compartment is prohibited.

Operating with naked flames near or inside the installation compartment is prohibited.

10.1 Product maintenance

Any maintenance operation on the product must be carried out by qualified personnel having an appropriate Refrigeration Engineer License regarding the knowledge and management of plants containing HC gases such as R290 (Propane). During any routine or extraordinary maintenance or failure the manufacturer recommends that maintenance personnel use a suitable HC gas detector equipped with the necessary safety devices to prevent ignition in the presence of a potentially explosive atmosphere. Always ensure adequate ventilation of the installation compartment before carrying out any work on the product, as the refrigerant gas used is odorless.

Maintenance personnel must therefore implement all the procedures and precautions necessary to prevent any dangerous situation in the presence of a flammable gas.

The product does not have a charging or recharging valve, as this operation cannot and must not be performed for any reason on site. In case of a leak in the refrigeration circuit or if it is partially or entirely empty, the maintenance technician must have the entire system replaced.

During maintenance operations, the operator in charge must check the following points.

Installation conditions

Check that:

• The dimensions of the installation compartment are those specified in this manual.
• Sufficient ventilation of the room is ensured.
• The markings and graphic signs on the product are present and legible.
• There are no signs of damage or corrosion on the product that could impair its operation or cause refrigerant gas to escape.

In case of differences in the product installation conditions, maintenance personnel are required to inform the owner and proceed with elimination of the non-conformities found.

Checks and repairs of electrical components

Check that:

• There are no conditions of imminent danger for the operator;
• The circuit is not powered.
• If it is not possible to operate without power supply, make sure the owner has been notified regarding the situation.
• The electric capacitors have been safely discharged without producing sparks.
• There is continuity in the ground connection.
• The electrical components are replaced only with original spare parts.
• No cuts or joints are made on the cables of the electrical components.
• The cables and wires do not have any damage which could compromise the integrity of the product and the safety of people and/or property.

Note: Only original replacement electrical components are guaranteed by the manufacturer as safe and tested by a third party for use with flammable refrigerants

Leak detection

• Do not use any kind of flame to detect refrigerant leakage.
• Use electric detectors only if sure of their efficiency and safety in an explosive environment; for this purpose the instrument must be able to detect an R290 leak equivalent to a maximum of 25% of the LFL (Lower Flammability Level).
• Alternatively, specific leak detector sprays can be used for refrigerant gases; the product used must be non-corrosive type.

In order to be used safely, the leak detection instruments must have a calibration tool normally called a calibrated leak. Checking the sensitivity of the detector with the aid of the calibration tool must be carried out far from the place of installation in order to ensure correct calibration.
