Increase the set point temperature: Press the key Decrease the set point temperature: Press the key Never press the PGM and EXIT keys For other settings, please contact Atlantic. Information on the control panel Identification number plate on the control panel The maximum acceptable current is Icw = 23 kA.
INSTALLATION The “multi-elec” electric boiler should be installed in a louvered plantroom in order to ensure an ambient temperature below 30ºC and relative humidity between 30 and 80%. The boiler should not be used in a corrosive atmosphere or in an external position. Adequate access should be left around the boiler in order to carry out maintenance.
STARTING THE BOILER Remove the power fuses Check that the boiler is filled with water Check that the immersion heaters are sound. If isolation is below 2MΏ, please find the reason and remdy it. Turn the power on using the main switch and the key switch ...
SERVICING Loss of water velocity through the boiler can lead to temperature rise Consider a sediment vessel on the return to capture sediment deposit Blocking immersion heaters irrigation can destroy them NOTE : The immersion heaters can be destroyed by blockage of the water flow It is essential that a periodical cleaning is carried out on the main heat exchanger and the sensors.

The following check list should be satisfied before the commissioning takes place. To arrange the commissioning Atlantic should be given a minimum of ten days notice of the date and time required.
