To block the setting – set the selected temperature by pulling off the thermostat knob without changing the setting

and you will find two pins on the back side of the knob; pull both of them and fit them into

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. The water heater shall only be mounted in vertical

position so that the lower edge of the heater was placed at least 600 mm above the floor (Fig. 4, 5). In combined

heaters, elbows have to be attached to the heating water inlet and outlet and, by turning them, the mounting either

from the right or from the left has to be determined (Fig. 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". 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 to the right. 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 5 days. Water may be dripping off the drain pipe of the safety valve; the pipe must be open into the

air, pointed down; environment temperatures must not drop below zero.

When draining the heater, use a recommended

drain valve. First, close water input into the

heater.

Find necessary pressure values in the following

table.

For proper safety valve operation, a backflow

valve must be mounted on the inlet pipes,

preventing spontaneous heater draining and hot water penetrating back into the water main.

When assembling the security equipment, follow ČSN 06 0830.
