PUTTING THE HEATER INTO OPERATION
After connecting the heater to the water supply, the hot water heating system, the electric network, and after testing
its safety valve (based on the valve manual attached), the heater may be put into operation.
Procedure:
a) Check both water and electric installation; for combined heaters, check also the installation to the hot water
heating system. Check proper placement of thermostat sensors; The sensors in the thermowell have to be
inserted all the way.
b) Open the hot water valve on the combination faucet
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) When heating service water with electric energy from the hot water heating system, open the heating water
inlet and outlet valves, possibly de-aerate the heat exchanger.
h) When commencing operation, flush the heater until the cloudiness in the water is gone.
i) 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 discharging water from the heater, the combination faucet valve for hot water must be open in order to avoid
creating underpressure that would prevent water discharge.

IMPORTANT NOTICES
−
Check and exchange the Mg anode regularly.
−
No stop valves can be put between the heater and the safety valve.
−
If the overpressure in the eater main exceeds 0.6 MPa, a reduction valve must be mounted before the
safety valve.
−
All outlets of hot water must be equipped with 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, setting, and regulation feature exchange, may only be implemented
by a service company.
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 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 product packages to a waste disposal place designated to that purpose by the
municipality. When the operation terminates, disassemble and transport the discarded and
unserviceable heater to a waste recycling centre (collecting yard), or contact the
manufacturer.
