Connection to water mains
The water heater shall be connected to the water mains with water pressure 

from 0.03 to 0.6 MPa. The water heater can be fed with water from a tank, 

where water level shall be at least by 4 m above the water heater level

NOTE:

nstallation of the water heater in the operation place and 

arrangement of a power supply line shall be performed 

by a specialized organization, representatives of the 

manufacturer’s service department, or specialists 

having permits for installation of electric equipment 

with observations of safety requirements.
If the installation and operation instruction manual 

of the water heater is violated, the appliance is not 

subject to warranty service and the manufacturer does 

not bears the responsibility.

NOTE:

Before installation of the water heater, flush water 

pipes with flowing water.

Fig. 2

When pressure in the water mains exceeds 0.6 MPa, OBLIGATORY 

installation of a pressure reducing valve is required.

It is recommended to use a shutoff safety valve at the cold water inlet.

Connect the water heater to the water pipeline (threaded pipe outlet with 

obligatory installation of a valve to shut off water feed to the water heater) 

using a separate flexible hose (! not included to the package).

CERTAINLY install all sealing gaskets included to the package and coarse 

filter, which is fitted at the cold water inlet.

At that, it is necessary to observe the OBLIGATORY REQUIREMENT

:

The water feed shutoff valve shall be installed upstream of the water heater 

inlet.(Proper installation of the water heater is shown in Fig.2)

PROHIBITED:
Installation of a shutoff valve at the hot water outlet from the water 

heater.

 (Fig.2a) This will result in failure of the water heater and may inflict 

harm to the user.

Make sure that the water heater is operable passing water flow through it.

Check tightness of all connections and, if necessary, tighten nuts and 

mounting screws including screws in flanges of the heating vessel.

Connection to electric mains

The water heater shall be connected to the 220VAC electric mains with a 

three-core electric cable (not more than 15 m long to the maximum).

Minimum wire section of 3x1.5 mm2 (copper) with a 16A circuit breaker - 

for water heaters of WHEL-3... series

Minimum wire section of 3x2.5 mm2 (copper) with a 25A circuit breaker - 

ATTANTIONS! 

When the water heater is operated in particularly 

difficult (including obsolete) water pipeline systems with 

a large quantity of suspended particles and impurities 

in flowing water, application of purification filters at 

the inlet of the water heater is OBLIGATORY. Use this 

recommendation; otherwise, non-fulfilment of this item 

may affect service life of the product and warranty 

service conditions (up to refusal of warranty liabilities 

by the product manufacturer and manufacturer’s 

service departments).
