Limiting the regulation range; locked settings.
For various safety reasons (unintentional scalding, preventing children or unauthorised person from handling), the
regulation range can be limited, or the setting on the thermostat blocked.
To limit regulation - pull off the thermostat knob (it will be tough at first) and you will find two cylindrical pins
2,15mm on the back side of the knob
- pull off one pin and insert it to the corresponding hole of the selected maximum temperature.
- put the knob back on (to the stop).
To block the setting – set the selected temperature
pull off the thermostat knob without changing the setting, there are two pins on the back side of
the knob
Pull off both of them and fit them to the holes corresponding with the selected temperature so
that the gap between the pins was without a hole, and the position was opposite the set
temperature.

WALL MOUNTING
Prior to mounting, check the loading capacity of the wall and, depending on the type of masonry, choose a
suitable anchorage material, or reinforce the wall, if needed.
that, from the front view, the right edge of the heater was placed at least 600mm from the opposite wall (Fig.
3, 4). In combined and electric heaters, elbows have to be attached to the hot service water inlet and outlet
prior to their suspension in brackets right under the ceiling and, by turning these elbows, mounting left has to
be determined - either from the right, or from the left (Fig. 1; 2).
With regard to various types of carrying masonry and broad assortment of special anchorage material
available at the market, we do not provide heaters with this material. The anchorage system has to be selected
individually, depending on the conditions. We recommend an authorised company perform mounting on the wall
and anchorage, or discuss the anchorage with a professional.

PLUMBING FIXTURE
Connection of heaters to plumbing fixtures is illustrated on Figures 1 and 2. For potential disconnection of the
heater, the service water inlets and outlets must be provided with screw coupling Js 3/4".For operation, the heater must
be equipped with a safety valve. Safety valve is mounted on the cold water inlet identified with a blue ring.
The heaters must be equipped with a drain valve.
Each hot service water pressure heater must have a membrane spring loaded with a safety valve. The safety valve
must be easily accessible, as close to the heater as possible. The input pipes must have at least the same clearance as
the safety valve. The safety valve is placed high enough to secure dripping water drain by gravity. We recommend
mounting the safety valve onto a branch pipe. This allows easier exchange without having to drain the water from the
heater. Safety valves with fixed pressure settings from the manufacturer are used for the assembly. Starting pressure of
a safety valve must be identical to the maximum allowed heater pressure, and at least 20% higher than the maximum
pressure in the water main. If the water main pressure exceeds such value, a reduction valve must be added to the
system. No stop valves can be put between the heater and the safety valve. During the assembly, follow the guide
provided by the safety equipment manufacturer. It is necessary to check the safety valve each time before putting it
into operation. It is checked by manual moving of the membrane from the seat, turning the make-and-break device
button always in the direction of the arrow. After being turned, the button must click back into a notch. Proper
function of the make-and-break device results in water draining through the safety valve outlet pipe. In common
operation, such a check needs to be implemented at least once a month, and after each heater shutdown for more than
