PROPER ASSEMBLY IMPROPER ASSEMBLY
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.
NOTE:
Before installation of the water heater, flush water pipes with flowing
water.
ATTENTION!
It is prohibited to use the water heater without reliable grounding.
Connection to electric mains
1. The power cord is led in through the side face of the appliance.It is pro-
hibited to use a plug socket for connection of the water heater to the elec-
tric mains, except for WHN-4 OS, WHP-4 OS models.
2. The water heater shall be connected to the 220VAC electric mains with a
three-core copper electric cable having the following minimum wire
section:for WHN-4 OS, WHP-4 OS models - 3x1.5 mm2 and a 16A circuit
breaker; for WHN-5 OS, WHP-5 OS models - 3x2.5 mm2 and a 25A circuit
breaker.It is necessary to increase wire section, if the water heater and
4. For connection of power supply:
- Remove the front panel;
- Strip off insulation of the power wires to length not less than 7-10 mm and
strip off insulation of the grounding wire to length not less than 2-2.5 mm;
- Lead the electric cable through the side face in the rear panel of the appli-
ance enclosure cutting the electric cable gland at the center with a sharp
knife;
- Remove the clamping plate of the electric cable keeping the installation
screws and make sure that the cable does not cross sharp edges and does
not contact with hot surfaces;
- Connect the electric cable wires with the terminal block according to the
appliance marking (refer to Fig.6);
- Make sure that all clamping screws of the terminal block are secured.A
loose connection may result in heating of wires;
- Install the clamping plate of the electric cable to the main position using
the installation screws and make sure that the power cord cannot be re-
moved;
- 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;
- Install the front panel.

refusal of warranty liabilities by the product manufacturer and manufac-
turer's service departments).
electric cable itself are located on a thermally insulated or heating wall.
3. The water heater shall be connected to the 220VAC power supply
source permanently (except for WHN-4 OS, WHP-4 OS) with obligatory
connection to the electric grounding loop. Make sure that resistance of
the grounding loop is < 4 .
