Dimensional characteristics Water heater : mm

GENERAL POINTS The water heater with smooth-tube heat exchanger can be connected to each gas or oil furnace. The position of the heat exchangers provides complete heating of the water in the accumulator. The tank is protected by an enamel covering giving protection up to 850°C, in accordance with the requirements of DIN 4753. The water heater must be installed by an approved installer, in an area that is protected against freezing. Enamelled tanks are suitable for nor

mal domestic hot water and approved for mixed setups (copper tubing, zinc tubing). Unused connections must be blocked. The directives in force and the instructions from the local water service as well as DIN standards must be followed. The tank is linked to the hydraulic distribution network via a cold water connection and to usage points via a hot water connection. If hot water is taken from a usage point, cold water then enters the reservoir where it is heated to the temperature set using the thermostat (not provided with the product). It is advisable to maintain the water temperature between 60° and 65°C, as this guarantees the best performance for the unit and ensures the following: - Maximum level of hygiene, - Maximum limit for thermal loss, - Limiting the formation of limescale deposits. INSTALLATION Installation instructions ONLY HIGHLY QUALIFIED PERSONNEL ARE AUTHORISED TO PERFORM THIS OPERATION, OTHERWISE THE WARRANTY WILL BECOME VOID The information given below determines the validity of the warranty.

1. The installation must:

a. Be installed by a qualied installer. You must conform to current national standards. It is necessary to respect the instructions for the water heater, b. Provide, when necessary, a pressure reducer for inlet water, c. The system is required to have a safety assembly (maximum calibration: 7 bar) which must be installed with the unit in a location where there is no possibility of freezing.

2. The storage temperature must remain below 90°C.

3. To prevent corrosion, it is necessary to regularly check the charge level of the battery that supplies the protech spark plug and replace it if there is a fault. 4. In case of installation in a location above a living area (roof space, attics, suspended ceilings, etc.), insulate the pipes and provide a holding tank with water evacuation. In all cases, a connection to mains drainage is necessary. Recommended installation space For maintenance operations to take place, there must be: - a clear space of at least 50 cm in front of the plastic cover to allow access to the electrical components, - direct access to the safety assembly, - particular case of installation in a bathroom (NF C15 100). Denition : Space envelope (A): The space envelope is the space outside the bathtub or the shower basin, and is limited on one side by the vertical cylindrical surface around the bathtub or shower basin, and on the other side by the horizontal plane 2.25 m from the base of the bathtub or shower tray. Protection space (B): The protection space is the accessibility area for a person inside the bathtub or the shower basin, which lies outside the spa

ce envelope. It is limited by the vertical cylindrical surface 0.60 m from the base of the bathtub or the shower basin and limited by a horizontal plane located 2.25 m above the base of the bathtub or shower basin. This standard is applicable in France, and of course the installer must re- main aware of any changes to this standard. For installation in other coun

tries, please refer to the applicable local regulations. Advice : To prevent overconsumption of energy, it is recommended that the heater be positioned as closely as possible to the hot water usage points. (a distance of less than 8 metres is recommended).22 Technical Installation Instructions and User Guide

Safety assembly The unit must be installed with a safety assembly that meets current national and EU standards, connected to the cold water inlet tube and suitable for the maximum working pressure indicated on the technical label. It is advisable to use a safety assembly with a membrane. The safety assembly must be installed as close as possible to the cold water inlet and the water ow must not be obstructed by other acces

sories. If, for technical reasons, the safety assembly cannot be installed with a direct link to the cold water inlet, a rigid link must be used. In any case, the link must be made using a material that is able to withstand the temperatures and pressures indicated on the technical label. The outlet for the safety assembly should never be obstructed and should be linked to vertical evacuation tubes with a diameter at least as large as that of the unit's connections. It is recommended that the safety assembly be installed as low down as possible so that the unit can be drained suciently. If the supply pressure is greater than 4/5 bar, a pressure reducer must be installed upstream of the safety assembly. It is recommended that a stop valve be positioned upstream of the safety assembly. Always use new connection piping to make connections to a water supply network, never install used pipes. These pipes must also conform to the EN 61770 standard. Water connection and preliminary operations - Verify that the useful thermal power from the generator exceeds the power that the tank can absorb by more than 15%. - Verify that the volumes and the pre-charge pressure of the secondary circuit expansion reservoir are suitable for the system. - If the water in the circuit is excessively hard, install (upstream of the tank), a correctly adjusted water softener. - If impurities are found in the water in the circuit, install a suitable lter, making sure that the circulators have sucient ow and a sucient extractor and that they rotate regularly. - Verify that the thermostat sensor is correctly positioned. - Verify that the thermostat controls are functioning correctly. - Install a safety assembly that meets current national and EU standards, and which is suitable for the maximum working pressure indicated on the product identication label.23 Technical Installation Instructions and User Guide

STARTING UP For domestic water use, ll the accumulator with cold water and remove the air from the circuit by opening a valve to decant the hot water. Fill the primary circuit's hot water exchanger and remove the air from the unit. Set the temperature for domestic hot water in the tank by adjusting the thermostat (not provided with the unit). It is strongly advised to maintain the temperature between 60° and 65°C. Only a qualied technician is authorised to start up the unit. Regularly check that all the control, regulation and testing devices are functioning properly. OPERATION This tank allows hot water to be provided easily, for domestic use as well as industrial use. The tank is linked to the hydraulic distribution network via a cold water connection and to usage points via a hot water connection. If hot water is taken from a usage point, cold water then enters the reservoir where it is heated to the temperature set using the thermostat (not provided with the product). It is advisable to maintain the temperature between 60° and 65°C, as this guarantees the best performance for the unit and ensures the following: - Maximum level of hygiene, - Maximum limit for thermal loss, - Limiting the formation of limescale deposits. The water in the tank's reservoir is heated through inow of the primary hot water that ows through the coil inside the unit. Important: - The unit must never be turned on when it is empty, as this risks damaging its electrical components. - Never block the safety assembly opening.27 Technical Installation Instructions and User Guide

PROTECH The PROFESSIONAL TECH system, an exclusive solution, is an electronic system which protects against corrosion and ensures the maximum life of your water heating tank, even where water quality is poor. The electronic circuit allows a dierence in potential to be created between the tank and the titanium electrode, in such a way as to guarantee optimum protection of the tank and prevent corrosion. Optimum functioning of the protection system REQUIRES A PERMANENT CONNECTION TO A 230V SUPPLY, even when the hot water generator is not running. To be able to disconnect the protection system for longer than 2 hours without risking the length of the tank's useful life, it is essential to drain the tank beforehand! !! The electronic circuit is linked to the 230V network, and also to the tank being protected and the titanium protection electrode, as shown in the diagram on the following page. Correct functioning of the protection system is indicated by the green indicator light coming on, which shows that the circuit terminals are live. In case of a fault, the red indicator light will signal that there is a short circuit between the electrode and the tank, that one of the cables (tank or electrode) is detached, or that there is no water in the tank. Therefore, your hot water generator is correctly protected if the green indicator light is on and the red light is o. If this is not the case, please call your installer. Note for the installer Important: do not carry out any operation without having rst cut the electricity supply from the 230V network, (as this is a quick operation, it can be carried out without rst draining the tank and not necessarily cause corrosion). The electronic circuit can be replaced very easily, without draining the tank, by: - Unplugging the two supply lines that lead from the electronic circuit to the supply terminal block, - Unplugging the quick connector with polarising slot that links the circuit to the tank and the electrode, - Detaching the electronic circuit from its support (plastic clips in the 4 corners), - To replace a defective circuit with a new one, perform the above steps in reverse order. Diagnosing electronic circuit failure

GREEN light is not on : -- Verify that the circuit supply line is plugged in (if not, plug it in), - Check that the electronic circuit is being supplied (if not, replace the supply cable), - Verify that the power being supplied is 230V (if not, supply 230V), - If all the above have been veried and there is still a fault, replace the electronic circuit (installer).

RED light is on : - Verify that the tank is full of water (if not, ll it so that the following checks can be carried out), - Verify that the quick connector is properly positioned (if not, correct this), - Verify that the electrode connection cable (that enters the glove nger in the base) is properly connected (pull it gently from above to make sure it is connected) (if not, replace the base and its electrode), - Verify that the tank connection cable is properly connected to the tank (if not, connect it correctly), - Verify that the two cables coming from the quick connector are not damaged or stripped, etc. (if they are, replace the base and its electrode), - If all the above have been veried and there is still a fault, replace the electronic circuit (installer). Request the assistance of your installer.28 Technical Installation Instructions and User Guide

THE CURRENT MUST BE CUT BEFORE ANY OPERATION IS CARRIED OUT ON THE UNIT All operations must be carried out by a qualied technician. We recommend subscribing to a maintenance contract and planning to replace the safety assembly at least every 5 years, if necessary. Every year (twice a year if the water is treated by a water softener), the unit must be drained so that the Protech anode can be checked to make sure it is functioning properly. For these operations, contact your trusted installer. Exterior cleaning The external parts of the tank must be cleaned using a damp cloth and appropriate cleaning products that are available commercially. In any case, the use of abrasive products, solvents, spirits, alcohol, etc. is not recommended. Draining Unplug the water heater and the hydraulic supply. Open the hot water valve to let air in. Open the drainage valve on the safety assembly. Remove limescale In cases of very hard water, it is advisable to remove limescale at least twice a year. To do this, it is rst of all necessary to empty the hot water tank and then remove the upper ange to be able to ac

cess the interior. Carry out the task using a suction device and a plastic or wooden brush (to remove the most resistant sediment). Clean it again and rinse it with a spray of water. While cleaning, be careful not to damage the enamel layer that protects the inside of the reservoir. Replace the upper ange, install a new seal and ll the reservoir, making sure there are no leaks.
