1 IMPORTANT INFORMATION The boiler’s guarantee does not cover any damaged caused by the non-observance of any of these instructions. This manual must be conserved and given to any new user. This appliance is not destined for use by anyone (including children) with reduced physical, sensorial or mental capacities or those who do not know how to use the appliance, unless they are supervised or instructed by a person responsible for their safety.
The boiler must be located in a place free from frost and moisture. This boiler is not designed to be installed in the open air. The boiler must be installed in an upright position. The boiler must be located above 200 mm above any object to allow the heating elements to be replaced. Please maintain the shown clearances around the CMX and CM boiler. 10 200 10 The boiler must be installed in a solid wall able of resist the weight of the boiler when full of water.
• • • • • • • • • • • • • • • • • Ensure that the mains voltage available coincides with that shown on the rating label. The electrical installation must comply with the current regulations. The cross-section of the power conductors must be sufficient for the rated power or the power to which the boiler has been limited. Install the necessary electrical protections as indicated in the current regulations.
3 COMMISSIONING 3.1 HEATING Check that the drainage points located in the lower part of the installation are completely closed. Open the purges of the installation and the boiler. Use a good corrosion inhibitor in the heating system. Use the inhibitor according to the manufacturer’s instructions. The heating system should be filled using the approved installed filling loop until the water pressure gauge reads between approximately 1 and 1.5 bar.
4 LIMITATION OF THE MAXIMUM OUTPUT It is possible to limit the maximum output of the boilers by selecting the combination required in the table corresponding to each model. The boiler output will never exceed the selected value. The boiler will continue to modulate in heating mode on all the lower steps, adapting to the installation’s consumption. It is necessary to employ an external ambient thermostat or a chrono thermostat. The output in S.H.W.

6 USING THE BOILER 6.1 TURNING ON AND OFF When the boiler is connected to the mains it will perform a general self-check and, if any defect is detected, it will be indicated on the heating or S.H.W. displays. Push the button to start the boiler up. The same button will turn the boiler off when pushed again. If the heating display only shows a small red dot, the heating function is switched off. To start the heating, push the button. The same occurs with the Sanitary Hot Water (S.H.W.
We can modify the setting of the temperature of the water by pushing either the and using the same buttons to adjust the value that flashes on the display. The modified setting will be stored after a few seconds or instantly if we push the button or the button button. If the setting is higher than the actual temperature of the heating water and the S.H.W is not connected, the heating will connect and a small red indicator of the consumption of heating resistances will light up.
6.3.4 Heater safety FLOW FAILURE If the error E3 appears on the display, the boiler has detected a flow failure in the heating circuit. The possible causes of this error are: - A blocked pump. All the thermostat valves are closed and there is no circuit that permits the water return. The circuit pressure is insufficient. The heating circuit is blocked. After solving the cause of the error, the boiler must be turned off and re-started to eliminate the display message.
6.4 .4 SANITARY HOT WATER (S.H.W.) The CMX15 and CMX18 boilers have a mixed function of modulated heating and the preparation prepa of sanitary hot water. The S.H.W. function has priority over the heating and so the outputs are never added together. A 50-litre litre header tank lagged with CFC free insulation accumulates the sanitary hot water. 6.4.1 Adjusting the S.H.W. temperature To switch on the S.H.W. push the button.
7 MAINTENANCE Gabarrón electric boilers do not need any special maintenance, only the following should be checked: -Check the pressure indicated by the pressure gauge frequently, ensuring that it is between 1 and 1.5 bar when cold. - Never start the boiler when it is empty. - Never start the boiler when the S.H.W. tank is empty; to fill it for the first time open a hot water tap and wait until water comes out of it. -Precaution against freezing.
