TECHNICAL DESCRIPTION

The water heater is intended for use only for domestic purposes in
the household and is used to heat water from common water
supply network, which composition and features comply with the
specified values in water quality legislation, such as its chlorides
composition should be less than 250 mg/l and its electric
conductivity should be more than 100 µS/cm, while its pH within
the limits of 6.5-8 for the water heaters with enameled water tanks,
and electric conductivity less than 200 µS/cm for the water heaters
with chrome-nickel steel water tanks.
Water heaters are divided into two main groups - working with
contained therein under pressure water and freely flowing water.
Pressurized water heaters are equipped with combined return
valve, which prevents runtime water pressure to exceed exposure
limits. Water heaters with free flow of water on only one consumer
(sink) are equipped with a special mixer and can only be installed
over the sink.
Water heaters are manufactured with two types of corrosion
protection of the water container - steel with durable enamel
coating and an additional cathodic protection of anodes with
special alloy or water containers, high chrome-nickel steel
(marked with the letter "H" in the number of modification). In
production are as well modifications with the anode status
indicator - anode tester ( "A").
The thermal insulation of the water container is of foamed
polyurethane.
Heaters with free flow are shown in Fig. 1, under pressure for
mounting over the sink - in Fig. 2, a pressure to be mounted under
the sink - in Fig. 3.
The parameters of basic water heaters with enameled water tank
are recorded in the table.
INSTALLATION OF THE WATER HEATER ON THE
WALL OF THE PREMISES
The water heater can be installed only in normal fire safeguarded
premises and where temperature cannot fall under 0°C. For water
heaters under pressure the availability of a siphon on the
installation for waste waters or another system of the same
purpose is needed, as during normal usage water may leak from
the safety valve aperture. At the same time the siphon will facilitate
the water tank maintenance, prevention and servicing operations
when water needs to be drained out of the water tank.
When choosing a place of installation the dimensions of the
device, its security from dripping water, method of attachment and
connection to water and electricity installations are taken into
account.
WARNING! The water heater is equipped with a power cord
with plug and can be installed in a room for bathing!
In the water heater packaging is placed a suspension plate (Fig. 4)
and 3 pcs. screws and dowels for concrete. With two of the dowels
and screws fasten the hanging plate securely to the wall of the
room. The location of the plate is selected so as to provide
sufficient space for the device and the fittings thereof, and its water
and electrical connections. For water heaters with free flow of
water mounted over a sink, the distance between the outlet of the
water supply pipe for cold water from the wall in which is located
the mixing tap and the dowel holes that must be drilled in the wall
are shown in the table. Attention! These distances are
approximate - the exact dimensions are determined by fitting the
specific device! The wall must be of sound and dense material
(such as concrete). It is unacceptable for hanging the unit on
decorative walls or made of hollow material. Once the plate
suspension is mounted, then the tank is hung on it. For this
purpose on the device rear side there are provided holes. After the
suspension of the appliance using the third set dowel and screw fix
the unit rigidly to the wall through the opening of the ear of its hull,
located to the side of the cover with the management bodies - see
Figures 1-3.
WARNING! Failure to comply with these requirements may
result in damage to the device, other devices and the room in
which the appliance is installed. In these cases, such damages
are not covered by the warranty obligations of the manufacturer
and the seller.
CONNECTION OF THE WATER HEATER TO THE
WATER SUPPLY NETWORK
Connecting water heater with a free flow
The connection of the water heater with free flow over a sink is
carried out in accordance with Fig. 1. IT IS COMPULSORY TO
USE the mixer and flexible pipes (hoses) placed in the original
package. The mixer is a special type and is intended to serve for
both hot and cold water from the appliance and to ensure free and
constant connection to the outlet pipe device (pipe for hot water)
with the atmosphere. The mixer is screwed in the wall to the
conduit for cold water. The connection of the hoses to the mixer
and heater are carried out in accordance with Fig. 1. Connect the
outlet from the mixer top on the side of the knob with red markings
to the pipe of the tank marked with a blue insert and arrow to the
pipe. The outlet from the upper side of the mixer on side of the knob
with a blue insert is connected with the tank pipe marked with a red
insert and arrow to the pipe. The hoses should not be crossed!
Such connection is a prerequisite for the water heater proper and
safe operation.
The water tank of the appliance is filled with water by the knob with
red marking and waiting until from the output of the mixer flows out
water. With this knob is regulated the flow of cold water in the water
tank. Warm water flows freely from the water tank through its
exhaust pipe, hose and the mixer output. After closing the knob
with red marking, the water in the outlet pipe of the appliance and
the hose for hot water flows out - this is not a defect and to avoid
damage to the mixer the knob with red marking should not be
tighten too much.
Connecting water heaters under pressure
With an arrow towards the pipe and blue color is marked the cold
water pipe and with an arrow from the pipe and red color insert - the
hot water pipe.
WARNING! IT IS MANDATORY in the cold water to the unit to
be mounted the supplied combined return valve and to keep the
arrow on the valve body indicating the direction of flow through
water flow.
IT IS PROHIBITED to mount any valve between the combined
valve and the water heater! It is absolutely forbidden to block
the side hole of the combined valve!
The connection of the water heater under pressure above sink is
carried out in accordance with Fig. 5.
The connection of the water heater under pressure under sink is
carried out in accordance with Fig. 6.
IT IS FORBIDDEN to install the combined valve in the space
above the unit!
