IMPORTANT! 

Please, use accessories, provided by the manu-

facturer, to install the water heater. Electric water 

heater must not be mounted on a wall prior you make 

sure that the bracket is installed firmly and securely. 

Otherwise the electric water heater may fall down 

from the wall, which may cause its damage and 

even serious accidents involving bodily injury. When 

determining points for bolt holes, it is necessary to 

provision some spare space between the lower part 

of the water heater and the floor, and as to the FSL2/

FSP2 line there also must be some space between 

the right side of the water heater and the wall on the 

right, not less than 0.6 m to make it convenient to 

perform maintenance if necessary.

Fig. 7 shows the way to mount the water heater for one consumption point.

1. Electric water heater should be mounted on a firm wall. If the wall is not 

robust enough to hold the weight equal to the doubled weight of the overall 

water heater weight, fully filled with water, then it should be mounted on a 

special support.

2. G1/2 diameter pipes are used to connect the water heater to the water 

pipeline.
3. To prevent a leakage when connecting pipes, use rubber sealing gaskets 

on the threaded pipe ends.
4. Screw a relief valve to the inlet nozzle, marked blue and embossed arrow 

of the water flow direction, so that the water flow direction coincides with 

direction of the arrow on the valve’s case.

5. Water heater with the mounted valve must be connected to the water 

main – install a shut-off valve at the water inlet point. You need to connect 

a drain pipe to the opening of the pressure relief of safety valve. Next you 

should put a drain pipe to the sewer.
6. Connect the desired number of consumption points to the outlet nozzle, 

marked red.
7. Check leak integrity of joints: open the shut-off cock and one of the cock 

assemblies. After the tank is filled with water, as evidenced by issue of water 

from the cock assembly, shut the cock assembly and check the leak integrity 

of all joints.

Connection to water main

1. The heater must be connected to water main with at least 0.1 MPa 

pressure; maximum pressure is 0.7 MPa.

NOTE:

In places or on the wall, where water may get to, the 

power outlet installation height must be not less than 

1.8 m.

NOTE:

Do not mount additional accessories, such as a shut-

off valve, between the relief valve and the inlet nozzle.

NOTE:

The water heater is the appliance, operating in such 

a manner that pressure of water in the water heater 

corresponds to the pressure of water in water main. 

If pressure in the main exceeds 0.7 MPa, then it is 

necessary to mount a pressure reducer before the 

water heater so that pressure doesn’t exceed 0.7 MPa.

** Depending on the product batch, GFCI can be located not within the power cable electric 

plug.

2. After you chose the proper place to install the water heater, determine 

points for holes for expansion hook bolts (to be determined in accordance 

with the data sheet for the appliance you chose). Drill two holes of the 

corresponding depth in the wall using a drill, dimensionally fit for expansion 

bolts, enclosed with the water heater, insert bolts, turn the hook upwards, 

securely tighten nuts and then hang the electric water heater on these hooks 

(see Fig. 8).
3. Fix a power outlet to the wall. Requirements to the outlet are as follows: 

230V/10A, single-phase, three-wired. It is recommended to place the outlet 

on the right side above the water heater.
4. If a bathroom is too small, the water heater can be installed elsewhere, 

unexposed to direct sunlight and unavailable for moisture. However, to 

reduce heat losses in pipelines, the location, where a water heater is to be 

installed, must be as close to the place, where hot water is used, as possible.
