Data Smooth straight pipe Smooth 90 ° curveGrille UM Type Effective length1 \ \ mEquivalent length1 2 2 m During operation, the heat pump tends to lower the room tem-perature if the air ducting is not to the outside. A suitable protection grille must be installed at the air extrac-tion 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 replace) 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 inow of combustion air in common with living areas. 5.4 Securing and connections of EGEAThe product must be installed on a stable, flat floor that is not subject to vibrations.5.5 Plumbing connections Connect the cold water supply line and the outlet line to the ap-propriate connection points (fig. 13).

5.6.1 Remote connections

The equipment is prearranged to be connected to other remote energy systems or energy meters (solar thermal, photovoltaic, Off-Peak) INPUTS

• Digital 1 (DIG1). NOT USABLE. (THE TWO WIRES, WHITE AND BROWN, OF THE 6-CORE CABLE ARE NOT TO BE USED).

• Digital 2 (DIG2). Digital input for photovoltaic. In case of a photovoltaic system connected to the plant, it can be used to subtract energy in the form of hot water in times of over- production. If there is a voltage-free contact, e.g. from the in- verter, which closes when there is overproduction of energy, it can be connected to the two green and yellow wires of the 6-core cable supplied with the.equipment. Set the parameter P23 = 1 to activate the supplement with photovoltaic.

• Digital 3 (DIG3). Input for Off-Peak. This function, available only in some countries, allows the equipment to be activated only when there is a signal coming from outside with prefer- ential tariff. If the electric contactor has a voltage-free contact which closes when the preferential tariff is available, it can be connected to the two gray and pink wires of the 6-core cable supplied with the equipment. Set the parameter P24 = 1 to activate Off-peak in ECO mode or P24 = 2 for Off-peak in AUTO mode.

5.6.1.1 Remote connection

ATTENTION!: Intervention of the safety thermo- stat 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 opera- tion 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 elimi- nate the fault, switch off the equipment and con- tact the Technical Assistance Service, communi- cating the model of the product purchased.EGEA 90LT - 120LT cod. 3541T580 - Rev. 03 - 05/2020

ATTENTION!: Any repairs to the equipment must be carried out by qualied personnel. Improper repairs can put the user in serious danger. If your equipment needs any repair, contact the service center. ATTENTION!: Before undertaking any mainte-nance operation make sure the equipment is not and cannot accidentally be electrically powered. Therefore, disconnect the power at every main-tenance or cleaning operation.9.1 Sacricial anode check/replacementThe magnesium (Mg) anode, also called "sacrificial" anode, pre-vents any eddy currents generated inside the boiler from trig-gering 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 an-odes, 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 per-formed by qualified personnel.Before doing the check:• Close the cold water inlet.• Proceed with emptying the boiler (see par. “9.2 Boiler empty-ing”).• 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 advis-able 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 quali-fied personnel according that prescribed in the chapter 10 of this manual.EGEA 90LT - 120LT

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 ap-pliance 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 10 m with ceiling at least 2 meters high, the air inlet and outlet must be ducted to the outside accord-ing to that given in par. 5.3 of this manual. The overall volume of the installation compartment must be greater than 20 m

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 quali-fied 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 installa-tion 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 installa-tion compartment is prohibited.EGEA 90LT - 120LT cod. 3541T580 - Rev. 03 - 05/2020

Any maintenance operation on the product must be carried out by qualified personnel having an appropriate Refrigeration En- gineer License regarding the knowledge and management of plants containing HC gases such as R290 (Propane). During any routine or extraordinary maintenance or failure the manu- facturer recommends that maintenance personnel use a suit- able HC gas detector equipped with the necessary safety devic- es to prevent ignition in the presence of a potentially explosive atmosphere. Always ensure adequate ventilation of the installa- tion compartment before carrying out any work on the product, as the refrigerant gas used is odorless. Maintenance personnel must therefore implement all the pro- cedures 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 par- tially 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 es- cape. 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 peo- ple and/or property. Note: Only original replacement electrical components are guar- anteed 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 safe- ty in an explosive environment; for this purpose the instru- ment 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. Check- ing 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 ensurer correct calibration.EGEA 90LT - 120LT
