material. The heat-transfer liquid must be with temperature not
higher than 85 °С and in its circuit must be installed a control
device set at this temperature in order not to allow thermal cut-out
of the electrical heating element during normal operation. The
pressure of the heat-transfer liquid in the heat exchangers must
not exceed the stated working pressure of the heater.
WATER HEATER INSTALLATION ON THE WALL
OF THE PREMISE
The water heater can be installed only in normal fire safeguarded
premises and where temperature cannot fall under 0 °C. The
availability of a siphon on the installation for waste waters as
during normal usage of the water heater, 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.
The type and nature of wall construction material, the appliance
dimensions, the way of fixing it, the location of its fixing elements
and tubes, its protection against dripping water must be taken into
account when choosing the proper place for installation. All these
data are duly marked on the appliance production plate with its
serial number. The appliance must be mounted where it is
protected against water dispersion or water pouring over. In order
to reduce heat loss it is recommended to keep minimum distance
between the heater and the places where the hot water is used.
If you purchased a water heater with factory-fitted power cord with
plug, the unit cannot be installed in a wet premise! The location of
the device must comply with the requirements for the electric
installation and its contact. Refer to the electrical connection of this
instruction.
It is obligatory that there are spaces provided between the
appliance and the surrounding walls and the ceiling of the premise,
as follow:
For vertical water heaters – at least 70 mm between the
џ
appliance and the ceiling; at least 50 mm between the
appliance and the side wall; at least 350 mm below the
appliance to facilitate servicing and possible repair.
For horizontal water heaters – at least 70 mm between the
џ
unit and the ceiling; at least 70 mm between the side cover
(outlets excluded) and the wall; at least 350 mm between the
electric part plastic cover and the wall to facilitate the
servicing and possible repair, and a sufficient distance below
the unit for installation of water connections and drain the
water from the tank.
In tanks with heat exchangers must be kept a distance from
џ
the coil terminals side and the joints for additional
thermostats necessary to connect the additional control and
safety units.
Water heater should be installed steadily on the wall of the
premises. For this purpose steel bolts (studs), tightly fixed in the
wall, with diameter 10-12 mm are used. The fixing elements should
be secured against pulling aside the wall – they should be anchor
or passage bolts (depending of the wall construction material). It is
recommended that the elements on which the heater will be
suspended are designed for three times greater loads than the
appliance total weight and located in the water therein. Installation
of the water heater on decorative walls (made of single bricks or of
other light materials) is strictly forbidden. On Fig. 1,2,3,7 and in the
tables are shown the distances between the bolts (studs) for
mounting the units.
WARNING! The bearing plates of horizontal water heaters
must be securely clamped to the premise wall. Under the bolts
heads (nuts on studs) must be placed support washers!
WARNING! Non observance of the requirements for fixing the
water heater on the wall may cause damages of the appliance,
damages on other appliances and the premises, where the
device is located, as well as corrosion of the casing or even
more serious failures and damages. In such cases eventual
failures and damages are not a subject to manufacturer and
seller warranty liabilities and will be at the expense of the party
which has not observed the present manual instructions.
The water heater mounting to the premise wall must be completed
only by a specialist.
WATER HEATER CONNECTION TO THE WATER
SUPPLY NETWORK
The plumbing to which the water heater will be connected, as well as
any other elements included in it shall have to withstand sustained
water temperatures above 80°C and for short periods - above
100°C, as well as to pressure at least twice high the appliance
working pressure.
Upon connection of the water heater to the water supply grid, the
arrows and indication rings around the water heater pipes for hot
and cold water must be observed (inlet and outlet pipes). With an
arrow towards the pipe and blue color is marked the cold water
pipe and an arrow starting from the pipe in red color - the hot water
pipe. Some appliances pipes are additionally marked with badges.
The pipes outlets are with threading 1/2". A schematic diagram for
water heater connection is shown on Fig 8. When the water heater
works at the water pipe tank pressure and that of the safety valve.
In the event where the conduit pressure is greater than 0,5 MPa it
shall be required the installation of reduce valve (pressure-
reducing valve). Where local regulations require use of additional
devices that are not included with the unit supply set and are not
placed in the packaging, these must be purchased and installed
according to regulations.
The water heater is equipped with a combined check-safety valve.
The latter is factory-fitted on the cold water pipe. Exception is made
for horizontal mounted water heaters with heat exchangers or
without and their modifications, where the pipes for hot and cold
water pass through the cylinder of the shell of the unit. For these
models the combined check-safety valve is located in a bag
attached to the appliance packaging and MUST OBLIGATORY be
mounted on the cold water pipe. During that installation follow the
arrow on its hull showing the direction of water flow through it.
WARNING! It is FORBIDDEN to install any kind of shut-off
fittings between the combined valve and the water heater! It is
absolutely forbidden to obstruct the lateral opening of the
combined valve and/or to block its lever!
Where the plumbing pipes are copper or of another metal, other
than that of the water tank, or where brass fasteners are used,
obligatory to install on the water tank inlet and outlet non-metallic
couplings (dielectric fittings).
ATTENTION! For units with heat exchangers. Any additional
tubular outlets (excluding those of the serpentines) that will be
connected with the plumbing, and the holes for additional
thermostats and / or thermomanometer must be closed with a
package insert or other suitable for the purpose. The connections
must be sealed for a water pressure of at least 1.6 Mpa.
It is recommended to set up a draining system for any dripping
