Instructions for use and maintenance

EN

1. 

Mounting 

We recommend the mounting of the device at close proximity to 

locations where hot water is used, in order to reduce heat losses during 

transportation. In the event the device is mounted in a bathroom, the 

selected location must exclude the possibility of water spray contact 

from the showerhead or portable showerhead attachment.

The appliance is affixed to a wall via the mounting brackets attached to 

the unit’s body (if the brackets are not attached to the unit’s body, they 

must be affixed in place via the provided bolts). Two hooks are used 

for suspending the appliance (min. Ø 10 mm) set firmly in the wall (not 

included in the mounting set). The mounting bracket’s construction 

designed for water heaters intended for vertical mounting is universal 

and allows a distance between the hooks of 220 to 310 mm (fig. 1a). For 

water heaters intended for horizontal mounting, the distances between 

the hooks vary for the different models and are specified in the table 

2 to Fig. 1c. For water heaters intended for floor installation - table 2 

to Fig. 1b.

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.

Notice

: the set does not include a protective tub and the user must 

select the same.

2. 

Water heater connection to the pipe network.

Fig. 3: a) - for vertical; b) - for horizontal installation; c) - for floor 

installation 

Where: 1 - Inlet pipe; 2 - Safety valve; 3 - reducing valve (for water main 

pressure > 0,6 MPa); 4 - Stop valve; 5 - Funnel connected to the sewer 

network; 6 – Hose; 7 - Drain water tap.

Upon connecting the water heater to the water mains you must consider 

the indicative color markings /rings/ affixed to the pipes: blue for cold /

incoming/ water, red for hot /outgoing/ water.

The mounting of the safety return-valve supplied with the water heater 

is obligatory. The safety return-valve must be mounted on the cold water 

supply pipe, in observance of the direction arrow stamped on its body, 

indicating the incoming water’s direction. Additional stopcocks must not 

be mounted between the safety return-valve and the water heater.

Exception: If the local regulations (norms) require the usage of another 

protection valve or mechanism (in accordance with EN 1487 or EN 

1489), then it must be bought additionally. For mechanisms operating in 

accordance with EN 1487 the announced operational pressure must be 

no more than 0.7 MPa. For other protection valves, the pressure at which 

they are calibrated must be 0.1 MPa lower than the one marked on the 

appliance’s sign. In these cases the safety valve which the appliance is 

supplied with should not be used.

The presence of other /old/ safety return-valves may lead to a 

breakdown of your appliance and they must be removed.

Other type of stopping armature is not allowed between the 

protection return valve (the protective device) and the appliance.

The attaching of the safety return-valve to threads longer than 

10 mm is not allowed, otherwise this may damage the valve 

and poses danger for your appliance.

With appliances for vertical assembly, the safety valve has to 

be connected to the ingoing pipe with the safety plastic panel 

of the appliance being taken off. 

The safety valve and the pipe between the valve and the water 

heater must be protected from freezing. During hose draining 

- its free end must be always open to the atmosphere (not to be 

immersed). Make sure that the hose is also protected from freezing.

Opening the cold-water stopcock of the water supply piping network 

and opening the hot-water stopcock of the water-mixing faucet 

carries out the filling of the water heater with water. After the filling 

is complete, a constant stream of water must begin to flow from the 

water-mixing faucet. Now you can close the hot water stopcock.

In the event you must empty the water heater, first you must cut off 

its power supply. The inflow of water from the water mains must first 

be terminated and the hot water tap of the mixing-faucet must be 

opened. The water tap 7 (fig 3a and 3b) 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 as follow:

 •

Models equipped with safety valve with lever - You can drain the 

water from the water heater by lifting the safety return-valve’s lever. 

Water will drain from the safety return-valve’s drainage opening

 •

Models equipped with safety valve without lever - water can be 

drain directly from inlet pipe of water tank after when you disconnect 

it from water main

In the event of removing the flange, the discharge of several liters of 

water, which remain in the water tank, is normal. 

Measures must be undertaken to prevent damage from 

discharging water during draining. 

In case that the pressure in the water mains is over the value 

pointed out in the above paragraph I, then it is necessary to 

assemble a pressure reduce valve, otherwise the water heater 

would not function properly. The Manufacturer does not assume 

any liability for problems arising out of the appliance’s improper 

use.

3. 

Water heater connection to the electrical network 

Make sure the appliance is full of water prior to switching on 

the electrical mains power.

3.1. 

Models with power cord with a plug are connected by 

inserting the plug into a contact. They are switched off the power 

supply by drawing the plug out of the contact.

The wall-plug must be properly connected to a separate electrical 

circle that is provided with a protector. It must be earthed.

3.2. 

The appliance has to be connected to a separate electricity 

circuit of the stationary electrical wiring. The connecting has to be 

constant- with no plug contacts. 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. 

The connecting of the conductors of the supply cord of the 

appliance has to be carried out as follows:

 •

conductor with brown insulation – to the phase conductor of 

the electrical wiring (L)

 •

conductor with blue insulation- to the neutral conductor of the 

wiring (N)

 •

conductor with yellow-green insulation – to the safety 

conductor of the wiring (

)

3.3. 

Models without power cord

The appliance has to be connected to a separate electricity circuit of 

the stationary electrical wiring. The circuit has to be supplied with a 

safety fuse 16A (20A for power > 3700W). Copper single core (rigid 

– non stranded) conductor shall be used for the connection – cable 

3 x 2.5 mm² (cable 3 x 2.5 mm² for power > 3700W).

The electrical circuit supplying the appliance must have an in-built 

device ensuring the splitting of all terminal poles under conditions 

of super-voltage of category III.

To install the power supply wire to the appliances remove the 

plastic cover. 

Connect the power wires in compliance with the marks on the 

terminals, as follows:

 •

the phase - to mark A, A1, L or L1;

 •

the neutral - to N (B or B1 or N1)

 •

The safety wire must be obligatory connected to the screw joint 

marked with 

. 

After the installation, put the plastic cover back in its place!
