USE

The TPK series heating flanges are designed as main heating devices for electric heaters from DZD type
OKCE S as secondary heating devices for OKC NTR(R)/BP, OKC NTR/HP, OKC NTRR/HP/SOL and accumulation
tanks of heating, solar and other systems. Heating flange can be used to heat water also in other facilities
provided the installation instructions are achieved. With their construction, they are only designed to heat
water up to tank pressure of 1 MPa and temperature of 110 °C.

DESCRIPTION

Heating flange is an enameled weld of flange and wells. TPK is equipped with a thermostat and a safety fuse
with external control and relevant electric installation. The electric wiring is placed underneath a plastic cover.

FUNCTION

After setting the heating temperature between 5 °C - 74 °C, the in-built PTK is unmanned. The thermostat
activates heating elements and after reaching the set temperature the thermostat turns off. The operation
of the element is indicated with lit up control glow lamps. If the thermostat fails, the safety fuse deactivates
power supply if 95 °C is reached. The safety fuse is non-reversible, i.e. that it has to be turned on once
the failure is removed.

ADVANTAGES OF USE

- Heating flange with elements in steel wells is more resistant in waters rich in calcium, with increased

formation of scale.

- Placing the elements in steel wells increases the lifetime of the heater tank. Electric potential is better

kept at corresponding values.

- If the element fails, it can be replaced without draining water from the tank.

ENERGY SAVING

Low water temperature in the heater proves to be especially economic. Therefore, the temperature should
be set to be adequate for intended hot water consumption, not higher. This helps to save electricity
and prevents lime sediment occurrence.

OPERATION AND TEMPERATURE SETTING

The temperature of water in the heater can be adjusted as needed by the thermostat, either continuously
or in three steps as indicated. This allows energetically economic operation. To set the temperature, 3 main
marked symbols are used:

• * accumulator freezing protection

• Approx. 60 °C, hot water - to prevent scalding, setting this degree is recommended as it is

the economic operation with minimum energy loss and minimum scale occurrence

• maximum, approx. 74 °C, hot water

Attention: When the thermostat wheel is in the utmost left position, this is not the zero position

nor is the heating turned off.

During day mode operation, the thermostat should not be set to temperatures above 60 °C.
