GENERAL INFORMATION FOR ELECTRICAL INSTALLATION
•
Check the insertion of the thermostat sensor in the thermowell, the so-called insertion all
the way.
•
The tank can be connected to any hot water heating boiler up to the 50 kW power output.
To adjust the distance from the wall, connect the wire of the external protective bonding!
•
The tank is powered directly from boiler by control voltage 230 V/50 Hz.
•
Elastic cable CYSY 4Cx0.75 can be used for cross connection.
•
Connecting terminals are identified on the tank's terminal board.

The control panel accommodates a capillary thermostat knob to set the desired water
temperature and an orange pilot light that is on when the tank's heating is on.
FIRST COMMISSIONING
To connect the tank to water supply system, hot water heating system, power supply and, after
testing the safety valve (accordingly with the manual attached to the valve), the tank can be put
in operation. Before opening the power supply, the tank must be filled with water. The process
of first heating must be executed by licensed professional who has to check it. Both the hot
water outlet pipe and safety armature parts may be hot.
During the heating process the pressurized connection water that increases its volume due to
heating must drip off the safety valve. In non-pressurized connection water drips off the
overflow combination faucet. When heating is finished, the set temperature and the actual
temperature of consumed water must be more-or-less the same. After connecting the heater to
the water main and electrical power system, and after checking the safety valve (following the
instructions attached to the valve), the heater can be put into operation.
- there is voltage on terminal 2 if tank is heated
- there is voltage on terminal 1 if tank is not heated
