c) Open the cold water inlet valve to the heater.

d) As soon as the water starts running through the hot water valve, the heater is filled and the valve closes.

e) In case of a leakage (flange lid), we recommend fastening the flange lid bolts.

f) Fasten the electric installation cover.

g) In case of service water heating by electric energy, turn on the electricity (for combined heaters, the heating

water valve at the heating water entry to heating insert must be closed).

h) When heating service water with electric energy from the hot water heating system, turn the electricity off

and open the valves of heating water input and output, possibly de-aerate the exchanger.

i) When commencing operation, flush the heater until the cloudiness in the water is gone.

Make sure to fill in properly the warranty certificate.

HEATER CLEANING AND ANODE ROD EXCHANGE

Repetitive water heating causes limestone sediment on both the tank walls and chiefly the flange lid.

The sedimentation depends on the hardness of water heated, its temperature, and amount of hot water consumed.

We recommend checking and cleaning the tank from scale and eventual replacement of the anode rod after two

years of operation. The anode life is theoretically calculated for two years of operation; however, it changes with

water hardness and chemical composition in the place of use. Based on such an inspection, the next term of anode rod

exchange may be determined. Have the company in charge of service affairs clean and exchange the anode. When

draining water from the heater, the combination faucet valve for hot water must be open, preventing occurrence of

under-pressure in the heater tank which would stop the water from draining.

IMPORTANT NOTICES

Without a confirmation of performed electrical installation issued by an authorised company, the

warranty certificate shall be void.

Check and exchange the Mg anode regularly.

You have to apply for approval of a local power supplier to connect the heater.

No stop valves can be put between the heater and the safety valve.

If the overpressure in the water main exceeds 0.48 Mpa, a pressure control valve must be mounted before the

safety valve.

All hot water outputs must have a combination faucet.

Before filling the heater with water for the first time, it is recommended to fasten the flange connection nuts of

the tank.

It is not allowed to handle the thermostat, aside from temperature resetting with a control button.

All electric installation handling, adjustment and replacement of the regulation elements shall only be performed

by an authorised service company.

The thermal fuse must not be turned off! In case of thermostat defect, the thermal fuse interrupts electric

power input to the heating element if the water temperature in the heater exceeds 90 °C.

As an exception, the thermal fuse may also switch off due to water overheating caused by overheating the hot

water heating system boiler (in case of a combined heater).

We recommend you operate the heater with one type of energy.

Disposal of packaging material and functionless product

A service fee for providing return and recovery of packaging

material has been paid for the packaging in which the water heater

was delivered.

The service fee was paid pursuant to Act No. 477/2001 Coll., as

amended, at EKO-KOM a.s. The client number of the company is

F06020274. Take the water boiler packages to a waste disposal

place determined by the town. When the operation terminates,

disassemble and transport the discarded and unserviceable heater

to a waste recycling centre (collecting yard), or contact the

manufacturer.
