from the opening of the safety valve. 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.
Dimensions of the appliance, the way of fixing, the location of the elements
for the fixing and the tubes, its protection against dripping water (as marked
on its serial number plate), the way of fixing and connection to the water
main and electrical installations should be taken into account when
choosing the proper place for installation. The appliance must be installed
where it is protected against water dispersion or water pouring over.
The water heater is designed for floor installation The place must be leveled
carefully. By screwing or unscrewing the unit feet is achieved its vertical
position.
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 guide instructions.
Installation of the water heater should be performed only by qualified
persons!
WATER HEATER CONNECTION TO THE WATER
SUPPLY NETWORK
All water tank outlets are marked with signs with the corresponding text.
Where the plumbing pipes are copper or of another metal, other than that of
the water tank, or where brass fasteners are used, it is compulsory to install
on all of the water tank inlet and outlet pipes non-metallic couplings
(dielectric fittings).
In the water heater packaging is placed a combined check-safety valve.
When connecting the device to the water supply network it is compulsory to
install the check-safety valve on the cold water pipe. The check safety valve
must not be installed in the space above the water heater. The arrow on the
valve body indicating the direction of water flow must be observed. The
lateral valve opening, intended to drain the expanded during heating water,
should point downwards.
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!
It is necessary to make a system for draining dripping water from the
combined valve lateral opening. This pipe will also capture the water flowing
out of the valve during prevention works. This draining pipe must have a
constant downward slope and located in frost secure environment and its
ends to be constantly kept open to the atmosphere.
The draining outlet must be sealed hermetically at water pressure of at least
1,6 МРа. We recommend to install on the draining outlet a suitable check
safety valve. Where necessary it shall ease the water drain from the unit.
In cases where recirculation shall not be used the system must also be
sealed watertight to water pressure at least 1.6 MPa.
In case of pressure of more than 0.5 MPa in the water within the pipe feeding
the tank, before the shut-off valve must be installed special lowering
pressure reducer valve (reducer) (See Fig. 2).
In the pipelines for hot and cold water to which the tank is connected may be
installed other elements that are prescribed by the system designer in order
to provide domestic hot water, but only on the places and in the manner
provided in the project.
Once the water heater is connected to the water supply main, its water tank
should be filled up with water. It is carried out in the following order:
џ Open completely the turn-cock for hot water of the most distant mixing
tap;
џ The shut-off valve opens;
џ Wait until a flow of dense and strong jet of water comes from the mixing
tab outlet;
џ Close the turn-cock for hot water of the mixing tap;
џ Lift the combined valve lever and wait for about 30-60 seconds until a
thick and powerful stream of water runs out from the valve side
opening;
џ Loose the lever of the combined valve.
WARNING! If no water is coming out of the opening of the combined valve or
the flow is weak (during normal water pressure), this should be considered
as a malfunction indicating that impurities from the plumbing or caused by
sewage connections have blocked the safety valve of the combined valve.
IT IS FORBIDDEN to proceed with appliance electric connection before
eliminating the reason for malfunction.
WARNING! Failure to comply with the requirements for connection to the
water supply system may cause partial filling up of the water tank and
malfunction of the heating element, or when the combined valve is not
installed at all or has been improperly installed this may even cause
destruction of the water tank, the room and/or other damages to tangible
and intangible property. Such consequences are not within the scope of
manufacturer or seller warranty liabilities and shall be at the expense of the
party, which has not observed the present manual instructions.
WARNING! The combined reciprocating safety valve is one of the unit
safety components ensuring security for water heater users. It is specifically
FORBIDDEN to use the water heater with a defective or
removed/unmounted combined safety valve!
WARNING! In case of possible temperature fall below 0 °С in the premise
where the water heater is installed it is compulsory to drain off the water
completely from its tank.
You may drain off the water from the tank with the shut-off valve installed to
the unit draining outlet as follows:
џ First close the shut-off valve installed on the pipeline feeding the
system with cold water - Fig.2.
џ Open the hot water cock of the closest mixing tap or disconnect the
tank hot water pipe connection.
џ Open valve installed to the unit draining outlet.
џ Wait until the water is completely drained off and stops flowing. The
outflowing water must be accordingly directed to a siphon for waste
water.
WARNING! When draining the water out of the water tank all necessary
precautions must be taken to prevent damages from flowing out water.
WARNING! IT IS FORBIDDEN to allow coolant circulation through the heat
exchanger when the unit water tank is empty.
The water heater connection to the water supply system must be performed
only by qualified persons.
WATER HEATER CONNECTION TO THE
POWER SUPPLY NETWORK
WARNING! Do not proceed to connect the water heater to the power supply
network unless you have made sure that its water tank is full with water!
Check!
The heat exchanger terminals are connected to the power supply network
as provided for in the system design for domestic hot water. It is necessary in
the coolant line to install a suitable expansion vessel and safety devices
preventing increasing its pressure above the recommended values.
WARNING! It is prohibited to fit stop valves or other devices with the same
objective on heat exchanger both ends (inlet and outlet) simultaneously. In
cases where the water heater heat exchanger shall not be used and is not
connected to the heat source circuit, it must be filled with propylene glycol
solution suitable for heating systems.
In order to assist the management of coolant flowing through the heat
exchanger, in the plastic cover of the unit is mounted a control panel with
user adjustable thermostat.
Connecting the heat exchanger of the water heater to an alternative heat
source circuit must be completed only by qualified technicians in the field
from a company specializing in such services and in accordance with the
design.
WATER HEATER CONNECTION TO THE
POWER SUPPLY EARTLING
Given the connection to the heater electric devices that help manage the
coolant flow it is necessary to connect the appliance to the room grounding
circuit in order to avoid the risk of electric shock.
The grounding wire is connected to the screw terminals of the flange plate,
located under the plastic cover on top of the unit. Its terminal is marked with
the sign of protective grounding.
WARNING! Failure to comply with the requirements concerning connection
