Connection to electric circuit:

- It is necessary to increase wire section, if the water heater and electric 

cable itself are located on a thermally insulated or heating wall.
- The water heater shall be connected to the electric mains stationly (exept 

WHEL-3...).
- Install an external circuit breaker for protection of the electric circuit 

(16/25/30A depending on series of the water heater).
- Lead the electric cable into the water heater.
- Fix bare ends of the electric cable in a connection box hardly tightening 

them with screws and in strict correspondence with the box marking (refer 

to Fig.3)
- Check connection tightness of all internal electric contacts including 

removable contact groups and bolt contact connections on heating 

elements. If there are loose connections, they shall be fixed and tightened.
- Connect the electric cable with the fixed method (exept WHEL-3...) 

to the 220VAC power supply source using a circuit breaker (16/25/30A 

depending on series of the water heater) with obligatory electric grounding.
- Install the enclosure of the water heater and tighten three mounting 

screws.
- Switch on the 220VAC power supply and check operability of the water 

heater with the practical method in all operation modes.

Water heater operation

- Feed water to the water heater and switch on electric power supply.
- Water flow is controlled by the mixer at the water inlet to the water heater. 

It is prohibited to install a mixer and/or shut off water feeding at outlet from 

the water heater.
- Water heating is activated using a switch (Fig.4; Fig.5)
- It is necessary to wait for 10-20 sec until temperature of heated water is 

ATTANTIONS! 

The water heater requires obligatory connection of 

electric grounding.

It is necessary to increase wire section, if the water 

heater and electric cable itself are located on a 

thermally insulated or heating wall.

The water heater shall be connected to the electric 

mains permanently (with a fixed method).
