The equipment can be mounted only on a flat, fixed surface. of furniture. Note! Minimum necessary distances/ free spaces for mounting are valid also for mounting with/ within pieces 8 Installation Danger! Danger of death by poisoning and explosion because of breeches in the gas pipes and connections in case of incorrect installation! Installation and commissioning can be done only by a company authorized and agreed by KÖBER SRL-Vaduri Branch! This company will assume responsibility for the correct installation and commissioning. 8.1 Conditions for the installation of the central heating station Installation directions Fig.1.3 The central heating station will be subject to corrosion from the moment it is filled with water! To receive warranty during the entire warranty period it is essential to take into consideration the following directions in order not to increase the corrosion! - The burning gas must have the sulphur content within the limits of the applicable European standard: it is accepted for a short period of time to have a maximum of 150 mg/m3, but the yearly average must be of 30 mg/m3. - The burning air must not contain chlorine, ammonia, alkaline agents, halogenated hydrocarbs, freon, plaster particles, lints, dirt or dust; - Installation of the central heating station in the proximity of a swimming pool, washing machine or cleaner can result in the contamination of the burning air with these compounds. - - Water ph must be within the following limits: 7,5<pH<9,,5 It is recommended to check the water and thermal agent ph frequently and if the value does not fall within the limits provided by the manufacturer, it will be treated again. - Water asperity must be within the limits 5 F <TH <15 F (5 F (French degrees), equivalent to 50 mg CaCO3 or an equivalent quantity of other Ca and Mg salts). - It is recommended to have repeated station startup cycles with the fuel tap off in order to air the installation. - If the central heating station is not used for a long period of time during the cold season, full emptying of the installation is recommended to prevent damage caused by freezing Protection of the station in order to keep the warranty Before and during installation, the central heating station must be kept away from impurities: construction dust, sand, copper dust, fats etc as well as welding splashes, scoria. In any of theses cases, the installation must be washed with clean water mixed with a highly concentrated cleaning agent. Genereally, in order to keep the warranty it is necessary to apply any neccesary treatment to prevent the contamination of water with the following: Black mud (magnetite - Fe3O4) formed as a result of the continuous electrolyte corrosion occurring in any installation which is not protected with an inhibitor. Red mud (rust - Fe2O3) produced during oxidation. Calcarous deposits produced especially on the hottest areas of the central heating station. A combination of these three factors mentioned above causes the majority of the problems occurring with heating systems. 6 din 17

7 The presence of these substances (black mud/ red mud/ calcarous deposits) means that the standard measures to prevent problems of the heating system were not observed. This is one of the causes resulting in losing warranty! 8.2 Gas connecting pipe Danger of death by poisoning and explosion because of breeches in the gas pipes and connections in case of incorrect installation! Installation of gas pipes is allowed to be performed only by an authorized agent. During installation all legal stipulations, as well as the local regulations of gas distribution companies are to be observed. When installing the gas pipe it is essential that it is not tensed so as not to create areas of leakage! Maximum safety pressure for the gas valve is 60 mbar! Going above this pressure limite may resul in damage. Work pressure with G20 natural gas functioning must be 20 mbar! Gas pressure at the entry into the gas valve if GPL gas is used must be maintained between mbar! Is is obligatory to istall a pressure regulator on the fuel input circuit, adjusted at 20 mbar. In case parasite voltage appears on the gas pipe, it can be insulated by installing an electroinsulating piece (according to the Technical Norms for the planning and execution of natural gas input systems). Central heating boilers C15SPV24MEFM/C17SPV31MEF function on GN natural gas or liquefied gas GPL. The gas connecting pipe is made of stainless steel with an interior diameter of 16.4 mm. The gas input pipe must not have a diameter smaller than that of the gas connecting pipe of the central heating station. The fuel input must be done according to applicable legal stipulations. 8.3 General directions for the heating installation Before connecting the central heating station carefully wash the entire heating installation! In this way, you eliminate from the pipes various debris such as welding splashes, scoria, grummet, putty, dirt or similar. Otherwise, these substances can form deposits in the heating switcher and can cause damage or malfunctioning. It is obligatory to install an impurity filter on the return of the thermal circuit installation! When installing connecting pipes it is essential for these not to be tensed to avoid creating areas of leakage! Maximum working pressure allowed is 3bar. Recommended working pressure is 1.5 bar! It is forbidden to use the central heating station without thermal agent or partilally filled danger of explosion! It is forbidden to use the central heating station if it is not completely aired! The equipment is provided with a 7l capacity and 1 bar loading pressure expansion vessel. Before installing the equipment, check whether this volume is sufficient. If not, an additional expansion vessel must be installed on the aspiration side of the pump. Check the pressure inside the expansion vessel before commissioning. Pressure inside the expansion vessel must be 0.8 1bar. 8.4 General directions for the hot water circuit Connect the central heating station to the hot water installation. It is obligatory to install filters to de-harden the water and a mechanical impurity filter on the cold water input connecting pipe! When installing connecting pipes it is essential for these not to be tensed to avoid creating areas of leakage! The apparition of pressure shocks (input pressures higher than 3-4 bars in addition to symoultaneously activating quick closing taps) can affect the components of the hydraulic circuit inside the central heating station. We recommend the installation of a pressure regulator adjusted to 3-4 bars! Damage caused by the apparition of pressure shocks or by the use of higher pressure than recommended on the cold water input circuit is not covered by the warranty! We recommend the installation of a pressure regulator! Damage caused by the use of pressure higher than recommended on the cold water input circuit is not covered by the warranty! It is forbidden to install one-way valves on the the cold water input circuit. The cold water input pipe of the hot water preparation circuit will always be open (closing the network is done only by activating the taps at the consumer points) to allow take-over of possible dilatations on this circuit. Note! It is recommended that the distance between the hot water connecting pipe of the central heation station and the nearest conumer is minimum 6m of pipe. Otherwiswe, there is always the risk of hot water burns. 7 din 17

8 8.5 Connecting pipe of the safety valve Danger of hot water burns! The connecting pipe of the pressing of the safety valve is connected to the drain pipe to the sewage system. Otherwise, there is always the risk of flooding, for which the manufacturer of the central heating station is not responsible. 8.6 Air/ burnt gases input/ output pipes The central heating station does not use air from the room where it is installed or from the neighbouring rooms. Admission of air necessary to an efficient and not dangerous burning is always from the outside. The kit will obligatory have an incline of 3% (approximately 2 ) in order to eliminate condensation towards the exterior. It is obligatory to install central heating stations in rooms with ventilation in accordance with applicable norms. Danger! It is forbidden to run the station without the air/ burnt gases input/ output pipes because it endangers the life and health of people. Installation is carried out only by authorized personnel using original spare parts provided by the manufacturer. In order to obtain the efficiency declared by the manufacturer, while at the same time observing the limits of compounds from resulting burning gases, it is necessary to mount the diaphragms delivered with the central heationg station. 8.7 Electric grid connection The central heating station must be connected to one-phase network of 230V - 50Hz with protection null. Dispersion withstand of the earthing switch (earthing) must comply with applicable norms (maximum 4 ohm, and the working null must not have residual current). Electric powering of the central heating station will be executed from a separate circuit provided with differential protection fuses of 30 ma. External connections must comply with applicable norms. Connection to the electric grid of the building must allow the entire electric insulataion of the central heating station for situations when interventions are required. Grid connection is done taking into account the symbolism of colours as follows: Brown = phase, Blue = null, Green and Yellow = earthing. The current plug must be accessible so that the user can easily disconnect it. It is not allowed to mount the central heating station with a defective electric installation or with no earthing. Danger of death by electric shock with electric contacts! 8.8 Installation filling and emptying The following operations are executed to fill the installation: - electrically power the central heating station; - open the filling tap (fig. 1.4) of the central heating station and of the thermal/ house water installation: - charge the boiler with a pressure of 0.4 bar shown on the display; - open the air vent of the pump; - activate the boiler pump to air the installation: for activation long press J7 ( ) and the pump will turn on, while the central heating station is OFF (Stand-by); - set the needed hydraulic characteristic on the pump (5, 6 or 7 m H2O); - continuue to charge the boiler up to 1.5 bar, pressure shown on the display; - close the filling tap of the central heating station; - check the system to be water-proof. If there is leakage, solve the problem; - leave the pump on until all noises on the installation stop.

10 Graphic context station startup When started, the station is in an intermediary state for 5 seconds, necessary to initialise the system. During this interval the diplay shows only the message On on the S1 symbol on the interface (see figure 1.6) Graphic context - Stand-by This context is associated with an inactive/ waiting state of the central heating station. In the stand-by state all the activation elements are inactive and every burning demand is ignored. An exception to the rule: the anti-freezing function (generated by a value of water temperature Fig.1.7 in the installation lower than 9 C, which will initiate a burning cycle to prevent the freezing of the thermal agent in the installation. Intrarea si iesirea din acest regim se face prin apasarea tastei POWER cel putin o secunda. Actiuni posibile: - POWER - comutarea intre starea ON/ Entering and exiting this regine is done by pressing POWER key for at least one second. Possible actions: - POWER comute between ON/OFF states; - LIGHT activation or deactivation of light functions. Figure 1.7 is a good example of display in the stand-by state (pressure on the thermal installation 1,8 bar) Graphic context error state The display of an error is sometimes asociated with a state of malfunctioning/ error of the station. There are three types of errors: - Critical errors: all the activating/state elements of the central heating station are inactive and any burning request is ignored. Getting out of this critical error state is done by pressing the RESET key; Fig Normal errors: all the activating/state elements of the central heating station are active and any burning request is ignored. Getting out of a normal error state is done by pressing the RESET key; - Informative errors: all the activating/state elements of the central heating station are active and all burning requests are accepted. Getting out of an informative state is done automatically when the cause of error disappears. In this context the diplay flashes a message with the error code. Possible actions: - RESET reset critical or normal errors; - LIGHT - activation or deactivation of light functions possible only if the central heating station is not in a state of critical error. Figura 1.8 is a good example of display of an error (in our case E20) Graphic context waiting state Waiting state is associated with a functioning state of the station, but with no burning request. All the activating/state elements of the central heating station are active and all burning requests are accepted if no error is present. In this state, the display shows pressure and thermal temperature, as well as the functioning mode summer/ winter. Fig.1.9 Possible actions: - POWER - comute between ON/OFF states; - IN/SU comute between summer/ winter functioning modes; - LIGHT - activation or deactivation of light functions; - CH+ - display and setting of maximum thermal temperature; - CH- - display and setting of minimum thermal temperature; - DHW+ - display and setting of maximum hot water temperature; - DHW- - display and setting of minimum hot water temperature. Figura 1.9 is an example of display in the waiting state (pressure in the heating installation is 1,4 bar, working mode is summer, and the temperature in the installation is 17 C) Graphic context functioning state This state is associated with the presence of flame or the functioning of the circulation pump of the station. In this state, all the activating/state elements of the central heating station are active and the burning request is accepted. The display shows the delivered instant temperature on the circuit meeting the request (heating ot hot water symbols S5 or S6), regardless of the presence or lack of flame, the pressure inside the installation and the functioning mode summer/ winter. Possible actions: - POWER - comute between ON/OFF states; - IN/SU comute between summer/ winter functioning modes; - LIGHT - activation or deactivation of light functions; - CH+ - display and setting of maximum thermal temperature; Fig CH- - display and setting of minimum thermal temperature; - DHW+ - display and setting of maximum hot water temperature; - DHW- - display and setting of minimum hot water temperature. Figures 1.10 and 1.11 are two examples of graphic display of this context. Figure 1.10 pressure in the heating installation is 1,8 bar, central heating station is in winter mode, flame is present, heating demand is satisfied and the instant thermal temperature is 43 C; Figura 1.11 pressure in the heating installation is 1,7 bar, central heating station is set on winter mode, flame is present, station deliveres hot water, and the instant hot water temperature is 53 C Graphic context adjustment of functioning parameters The adjustment of the main functions of the station (thermal temperature, hot water temperature) can be Fig.1.11 done both in the waiting state and in the functioning state When we enter the state display of these values, the last value previously set will be displayed. Only in the period the set value is displayed we can make changes of its value. Practically, at any moment of functioning of the station, by pressing J1 (CH+) or J2 (CH-) keys, the set value of the thermal temperature will be displayed and can be changed. 10 din 17

11 Similarlry, at any moment of functioning of the station, by pressing the J3 (DHW+) or J4 (DHW-) keys, the set value of the hot water temperature will be displayed and can be changed. While doing these settings, the display will show the value of the set temperature (thermal or hot water), the pressure in the installation and the functioning mode of the station (winter/ summer). Getting out of this setting mode is done automatically if no key is pressed for at least 3 seconds. Fig.1.12 Figures 1.12 and 1.13 are two examples of displaying temperature in the setting mode. Figure 1.12 pressure in the heating installation is 1,8 bar, central heating station is set on winter mode, set value of thermal temperature is 42 C; Figure 1.13 pressure in the heating installation 1,6 bar, central heating station is set on winter mode, set value of hot water temperature is 60 C. Fig Graphic context - Service submenu In the Service submenu, various functioning parameters of the central heating station can be viewed/ changed/ checked. This submenu can be accessed only by service personnel authorised by KOBER SRL Vaduri Branch, 9.2 Central heating station startup To startup the station press POWER key fig.1.5. Choosing the functioning mode winter/ summer By pressing J7 key ( ) you can change the functioning mode winter/ summer. This can be viewed on the display, symbol S5/S6 will be activated; Adjusting temperature on the thermal circuit The adjustment of temperature is done by pressing J1 and J2 keys. Press J1 to increase temperature and J2 respectively to decrease temperature; Adjusting water temperature on the hot water circuit The adjustment of temperature is done by presing J3 and J4 keys. Press J3 to increase temperature and J4 respectively to decrease temperature; 9.3 Functioning as waste hot water station (WHW) The station can function as WHW in both seasons winter and summer. The WHW request has priority over the heating request in the winter mode. The station can function as instant WHW or as accumulation boiler WHW (the boiler is purchased separately). For the functioning of the station as an accumulation boiler WHW station please contact an authorised service company. In intant regime, the minimum flow of hot water detected by the station is 2.4 l/min. For confort in using the station as a WHW station we recommend to exploit the station at a flow of approximately 7-8 l/min. When the station functions with low flows, the station functions continuously at the minimum charge as long as the hot water temperature is under the threshold limit of 63 C. When the hot water temperature reaches the mentioned limit of 63 C, the burner is closed and a new burning will happen when the hot water temperature is lower than the limit of 60 C. When the station functions with high flows, the hot water temperature will be the opposite of the hot water flow, but lower than the set temperature. With instant WHW configuration on request the CONFORT function can be activated/ deactivated. Please contact an authorized service company. This function allows the delivery of hot water as soon as possible, while keeping the boiler hot. If the function is active, the boiler starts when the hot water temperature is equal to the set hot water temperature; the boiler stops when the hot water temperature is 8 C ( fixed value) higher than the set hot water temperature. If the water heated in this way is not consumed within one hour, the CONFORT function is automatically deactivated. 9.4 Functioning as heating station (HS) The station functions in this mode when winter season is selected. For the selection of the type of heating installation (floor or radiators) please contact an authorised service company. If a thermoregulator is connected to the electronic board, the stations functions in thermal mode only when the surrounding temperature is lower than the set temperature in the thermoregulator. 9.5 Preset functions related to station safety 1. Anti-freezing protection function. If the temperature in the installation drops below 9 C, the system turns on the heating at minimum charge until the temperature reaches 30 C. 2. Post-circulation of the hot water and heating pump function. The post-circulation cycle starts only if the system is not in the BURNING state. Advantages: a) it prevents the water from becoming stationary at high temperatures inside the heat switch. In this way, calcareous deposits are reduced significantly b) it prevents water from boiling inside the heat switch in the post-heat interval. These advantages have as result the protection of the heat switch. 3. Pump anti-blocking system and three-way valve. If the station did not go through a burning cycle in the last 24h, the pump will be started for 12 seconds to avoid its blocking. In this time the three-way valve is also activated and deactivated. 4. Post-ventilation After each station stop, the ventilator still functions for some time to evacuate completely the burning gases out of the station and also the water vapours they contain. In this way, both the ventilator control electric circuit and the primary heat switch, which cools down partially, are protected. 5. Legionella bacteria prevention function This function is active for the functioning of the station as accumulation boiler WHW. When hot water is prepared in the boiler, the ANTILEGIONELLA function is actived automatically. This function implies that once a week (on Wednesdays, between 03AM 04AM) the temperature of the water in the boiler is kept at the value of 65 C. 9.6 Setting additional functions Setting additional functions is done only in the "Service" menu. Please contact an authorised service company. 11 din 17

13 9.8 Station switch off in safety conditions If the user observes abnormal functioning of the equipment, if error codes are displayed repreatedly or if the user cannot understand the actions of the central heating station, the user must stop the functioning of the station immediately and in maximum safety conditions. For this, the user must perform the following operations: - Press ON-OFF key and interrupt the functioning of the station; -Disconnect the central heating station from the main power line by unplugging it (if applicable); - Interrupt the fuel circuit by turning off the gas taps; -Interrupt the flow of house water and of heatined water by turning off the corresponding taps for these circuits; After the station is switched off in safety conditions, the user will contact the authorized service company in the area. 9.9 User training It is obligatory for the specialized personnel commissioning the station to instruct the user about the following aspects: 1. Central heating station switch on/ off procedure in safety conditions by checking the following elements: - electrical power connection; - fuel (gas) connection; - feeding and filling the thermal circuit; - the station filling tap must be turned off; - the pressure in the installation by reading the control panel (1.5bar); - the station taps on the house water circuit must be turned on. 2. The functioning way of the station and possible problems that may occur. Also each key and symbol on the control panel must be explained. 3. Warn the user that a drop in the water pressure of the system is caused by loss of thermal agent which needs to be mended before using the station again. 4. Warn the user on the works performed on the air/ gases input/ output systems. Warn the user that changing them is strictly forbidden. 5. It is recommended that the user should have the station verified by an authorized person at least once a year. 6. Warn the user about the the precautions that need to be taken against freezing. 7. Hand the user the user manual of the central heating station. At the end of training a commissioning statement is signed (table 2), by which the user signs that they are aware of the correct way of using the central heating station.. This statement is also signed by the authorized person who commissioned the central heating station. The authorised person who commissions the station has the right to refuse to sign the station commissioning statement if they notice defects of the local connecting installations and will not sign the commissioning statement until these defects have been remedied Quality Conditions and Warranty The company KÖBER S.R.L. - VADURI BRANCH as the manufacturer, guarantees the correct functioning of the central heating station if are observed ALL conditions for the installation, commissioning, use and periodical technical revision established in the Warranty Certificate given by the manufacturer and signed by the authorized company in the presence of the beneficiary when the product is purchased.
