Water heaters fitted with a supply cord without
a plug
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 and with inbuilt device to
ensure disconnection of all pole pieces in the conditions
of over-voltage from category III (a device with a distance
between the studs of at least 3 мм). The sections of its
conductors for the various powers are listed in Table 1.
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 (

Connecting:
•
Unscrew the four screws on the back of the appliance .
Remove the front panel
•
It is obligatory that the phase conductor is connected
to the terminal indicated by L, the neutral conductor
is connected to the N terminal and the safety one is
connected to the terminal indicated by
•
Put back the front panel of the appliance. Tighten the
four screws on the back.
•
Install the appliance to the holder (hook)
OPERATION METHOD
After accomplishing the heater installation and before
switching the power on, open the cock for flow control
until a steady water jet starts running from the outlet.
Do not turn on the supply voltage of the appliance if
there is a possibility for the water in it to be frozen.
ATTENTION! It is obligatory to do the following before
using the appliance after interruption and restoring of
the water supply, in regions where water supply is often
interrupted:
•
Switch off power to the appliance- if the model is
fitted with a cord and a plug – unplug it from the
socket. For the other models – switch off the shut-
down device built into the wiring of the appliance (see
item 3.1 and item 3.2 from section VI)
•
to fill the appliance with water – open the tap until a
steady jet of water starts running , not interrupted by
air from the water system
•
switch on the power to the appliance again
Do not use the appliance before you have made sure that
it is full of water!
When water runs or supply is interrupted, it is usual
to hear a sound from the switching over of the
automatic device for switching on and off of the
electrical heater.
Specific features of the various models:
1.
Models for the kitchen
The heater of the appliance switches on automatically
when you run water from the red-coloured handle of
the mixing tap. You can control the temperature of the
outgoing water by regulating the water jet from the
same handle. By increasing the water jet you lower the
temperature; when decreasing the jet the temperature
goes up. The heater switches off automatically when water
from the red-coloured tap stops running.
When you wish to use only cold water, use the blue-
coloured tap.
RECOMMENDATION! Control the temperature of the
hot water only by changing the water flow rate by
using the red-coloured tap. Do not mix hot and cold water.
It is possible that a little water leaks out of the outlet of the
spout after shutting the mixing tap. This is not a fault but
is caused by the emptying of the leading-out pipe of the
water tank because the appliance has a constantly open to
the atmosphere outlet.
Do not over-tighten the taps to their end position to
avoid damaging them!
Never block the S-spout and never shut the outlet of
the mixing tap. Regularly remove the scale from it.
