5.5. Connection of units withoutregulation

Unit – the fan operation – can be switched on and off only by the ON/OFF controls at the power supply to

the fan.

Switching/disconnection of the supply voltage can be solved by e.g.: timer, spatial thermostat.

Other regulation elements will not be connected to the regulator functionality. Their regulation must be

dealt with separately.

The supply voltage to the fan 1~230V/50-60Hz must not be modified in any way, otherwise there is a risk

of damage to the unit fan.

The fan connected in this way only operates at maximum speed and cannot be regulated.

If there are no objects in the unit that could damage the unit (e.g. tools);

If all the hydraulic connections are properly connected (tightness of the vent valve, connection branch and

the mounted valve);

If all electrical connections are connected correctly according to technical documentation, including

connection of regulation and accessories;

If the unit has all the assembly and installation screws tightened, and the lamellas properly deflected.

All connections must be made in accordance with the technical documentation supplied to the unit and

the documentation supplied to the control elements.

After the first start, check the basic functionality of the individual parts of the unit (fan operation, heating),

and also focus on the tightness of hydraulic system.

Check the other functions of the entire assembly according to the instructions for use of the selected

regulator.

Before any maintenance and cleaning of the unit, the unit must be disconnected from the power supply,

and the heating water supply to the unit exchanger must be switched off. Work must be carried out only

after the exchanger has cooled down. Otherwise, there is a risk of burns and injuries caused by rotating

parts!!!

Regular inspection of the unit, especially the water exchanger, is recommended to perform every 500 hours

of operation of the unit.

The unit must also be checked before the start and at the end of the heating season.

If the unit is not used for a longer period of time, it is necessary to switch off the supply voltage to the unit.
