2.4 FIRST COMMISSIONING

PROCEDURE OF FILLING THE TANK WITH WATER

1. Open the stop valve on the tank inlet

2. Open the hot water valve on the combination faucet. Once water starts flowing out through the

combination faucet the filling is completed and the faucet shuts off.

3. Check the joints for tightness.

4. When start using, keep flushing the tank until the cloud disappears.

5. Make sure to fill in properly the warranty certificate.

2.5 INSPECTION, MAINTENANCE & CARE FOR THE APPLIANCE

If water contains too many minerals, an expert has to come to remove the scale that forms

inside the tank, as well as free sediments. This has to be performed after one or two years

of operation. The cleaning is carried out through the hole in the flange – dismantle the flange

lid and clean the tank. A new sealing has to be used for re-fitting. Since the inside of the tank

has special enamel, which must not get in contact with the scale removing agent – do not work

with decalcification pump. Remove the lime layer with a timber and suck it off, or wipe it off

with a clout. After that, the appliance must be rinsed thoroughly and the heating process is

checked the same as during the initial putting in operation. Do not use any abrasive cleaning

agents (such as liquid sand, chemicals - acid, alkaline) or dye thinners (such as cellulose thinner,

trichlor, and the like) to clean the outer shell of the tank. For cleaning use a wet clout and add

a few drops of liquid cleaning agent for household applications. Repetitive water heating

causes lime scale sediment on both the tank walls and chiefly on the flange lid. The

sedimentation depends on the hardness of heated water, its temperature, and the 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. If the anode is only blocked with sediments clean its surface and, if used up, mount

a new one. Have a company in charge of service affairs deal with the cleaning and exchanging

of the anode. When draining water from the tank, the mixing faucet valve for hot water must

be open, preventing the occurrence of under-pressure in the tank receptacle that would stop

water from draining.

PROCEDURE OF EXCHANGING ANODE ROD IN UPPER PART OF THE TANK

Turn off control voltage to the tank

2. Drain water from 1/5 tank.

PROCEDURE: Close water inlet in the tank

Open the hot water valve on the combination faucet

Open the drain tap of the tank

3. Anode is screwed in under the plastic cover in the upper lid of the tank

4. Unscrew the anode using adequate wrench

5. Pull the anode out and follow reversed steps to install a new one

6. During the fitting, make sure the grounding cable (300-500l) is connected properly; this is the

condition of the anode's proper functioning

7. Fill the tank with water
