EN

4. 

In order to secure the water heater’s safe operation, the safety return-valve must undergo regular cleaning 

and inspections for normal functioning /the valve must not be obstructed/, and for the regions with highly 

calcareous water it must be cleaned from the accumulated lime scale. This service is not provided under 

warranty maintenance.

5. 

In order to prevent injury to user and third persons in the event of faults in the system for providing 

hot water, the appliance must be mounted in premises outfitted with floor hydro insulation and plumbing 

drainage. Don’t place objects, which are not waterproof under the appliance under any circumstances. In the 

event of mounting the appliance in premises not outfitted with floor hydro insulation, a protective tub with a 

plumbing drainage must be placed under the appliance.

6. 

During operation – regime of heating the water – water drops through the drainage opening of the protection 

valve are usual. The protection valve should be left open to the atmosphere. Measures should be taken to lead 

and collect the leakages in order to prevent damages.

7. 

If the probability exists for the premise’s temperature to fall below 0°С, the water heater must be drained.

In the event you must empty the water heater, first you must cut off its power supply. 

Draining procedure for boilers designed to be installed ABOVE SINKS: 

1. 

First shut the cold water supply valve  

2. 

Open the hot water valve on the mixing-faucet 

3. 

The water tap 7 (

fig 4a

) must be opened to drain the water from water tank. If there is no such tap 

build in the pipe line, than the water can be drain directly from inlet pipe of water tank after when 

you disconnect it from water main

Draining procedure for boilers designed to be installed UNDER SINKS: 

1. 

Switch the boiler off the power supply network.

2. 

Dismantle the connecting water fittings from the boiler.

3. 

Disassemble the boiler from its installation place, turn it so the pipes point to the floor and pour 

the water in a vessel you have prepared for the purpose. Wait until all the water drains out of the 

boiler.

Connection to the electrical network

----------------------------------------------------------------------------------------------------------------------------------------------------

1. 

Do not switch on the water heater unless you established it was filled with water.. 

2. 

Upon connecting the water heater to the electric mains care must be taken to connect the safety lead.

3. 

Models without power cord,  the circuit has to be supplied with a safety fuse (16A) and with inbuilt 

device to ensure disconnection of all pole pieces in the conditions of over-voltage from category III.

4. 

If the power supply cord (of models that have one) is damaged, it must be replaced by a service representative 

or a person with similar qualification, to avoid any risk.

5. 

During the heating the appliance could produce a hissing noise (the boiling water). This is common and 

does not indicate any damage. The noise gets higher with the time and the reason for this is the accumulation 

of limestone. To remove the noise the appliance must be cleaned from limestone. This type of cleaning is not 

covered by the warranty.
