Термекс Praktik 100 V ЭдЭ001641 [17/64] Possible faults and remedies

When performing maintenance condition of aluminum anode and scale on TÈH are checked. At the

same time residue that may accumulate in the bottom of the EWH is removed. If there is scale on TEH,

then it can be removed by using scale removing means or mechanically. When removing residuals from

EWH do not apply excessive force and do not use abrasive cleaners.

Importance of the first maintenance is that by intensity of scale and residues, aluminum anode

consumption terms for next maintenance services can be decided and, consequently, service life can be

extended. In case of non-observance of the above requirements EWH service life reduces, increases

the probability of EWH breakdown and validity of guarantee expires.

Put a rubber hose on the cold water supply inlet pipe or discharge valve and direct the second end to

џ

the drain.

Unscrew the relief valve or open drain valve.

џ

Open a hot water faucet on the mixer.

џ

Drain water from the EWH through cold water supply inlet pipe or discharge valve.

When conducting EWH maintenance by forces of special organization the appropriate mark shall be

made in the warranty card. When replacing the aluminum anode independently by the consumer

aluminum anode purchase receipt shall be attached to present manual.

Specifying security measures

Electrical safety and corrosion protection of EWH are guaranteed only if there is an effective

earthing in accordance with applicable electric installation rules and regulations.

When installing and operating EWH the following is not allowed:

To power EWH if EWH is not filled with water.

џ

If pressure in the supply line is more than 0.6 MPa, an appropriate pressure reducing valve

shall be installed at cold water inlet ahead of safety valve (not supplied) to reduce water

pressure to normal.

To connect EWH to the water supply without safety valve.

џ

To drain water from EWH with power switched on.

џ

To use spare parts not recommended by the manufacturer.

џ

џ

Water freezing in the appliance is prohibited because it causes its malfunction which is not a warranty

case.

Attention should be paid to children so that they do not play with EWH. EWH is not intended for use by

persons (including children) with limited physical, sensory or mental capabilities, or by persons who do

not know how to use the EWH, except for cases when this happens under the supervision or instructions

EN

by persons responsible for safety of the EWH.

Possible faults and remedies

If an operational fault occurs EWH shall be disconnected from the mains, water supply shall be cut off.
