5. Principles of heater operation
The properly installed DAFI heater used as intended is completely safe in
use. Before the installation of the heater and before putting it into operation,
it is absolutely necessary to observe the following conditions:
- the heater cannot be mounted in rooms, where temperature falls below
1°C.
- do not leave the damaged or disassembled heater connected to power
supply.
- use the electrical wires with minimum section which corresponds to the
rated current of the heater (see also section 6.2 of the instructions),
- observe unconditionally the sequence of connections,
- before connecting the heater to the power source, you must check whether
the heater is deaerated (see section 7.1 h of the instructions),
- it is prohibited to use a damaged or faulty device,
- it is prohibited to install the heater in shower enclosures.
Any use of the DAFI heater which is contrary to its purpose causes the
manufacturer to not accept the responsibility for the produced damage. The
manufacturer does not accept responsibility for the damage and effects re-
sulting from unauthorised modifications and repairs of the heater.
6. Sequence for connection of the device to the water supply system and
the wiring system.
In the first place, the DAFI water heater must be connected to the water system.
Only after deaeration of the water supply system and the heater, the device may be
connected to the wiring system.
6.1 Connection to the water supply system
The DAFI heaters are low-pressure devices and may operate in water supply ne-
tworks with the pressure of not less than 100 000 Pa and not more than 600 000
Pa. This may be the municipal water supply system or the local one with a pressure
booster, in the case of single-family buildings.
In the case of fluctuations of water pressure caused, among other things, by using
automatic flushing valves nearby the heater and in the case of pressure increase
above 600 000 Pa, install the pressure reducer.
WARNING - Do not switch on the heater if it is likely that the water in
the heater is frozen.
6.2 Connection to the wiring system
The heater with the power greater than 3.7 kW must be connected
on a permanent basis to the wiring system provided with the earthing
terminal.
