CONNECTING THE SYSTEM TO THE MAIN WATER SUPPLY
EN
NETWORK
IMPORTANT! Connecting the waterheater to the main water supply network
should be fulfilled in compliance with a project created by a hvac designer!
A Presence of WRITTEN DOCUMENT for additional components is required for
warranty recognition! Only qualified technicians must install this device!
Installation of the device with one heat exchanger should be done in accordance
with Fig.24. Installation of the storage tank with two heat exchangers should be
done in accordance with Fig.23. Models without heat exchangers – the same as for
models with one or two heat exchangers. Parallel installation acc. to Fig.25.
OBLIGATORY elements of installations are:
•
Inlet pipe.
•
Main water tap.
•
Pressure regulator. When pressure in the mains is over 6 bars it is required. In this
case, the set pressure is according to the calculations of the designer, but should be
not higher than 0.5 MPa! When pressure in the mains is under 6 bar, its presence is
strongly recommended. In all cases the presence of a pressure regulator set at 0.4
MPa is important for the proper functioning of your device!
•
Non-return valve. Its type should be defined by HVAC designer according to the
local and European lows, standards and technical norms.
•
Safety valve. Use only safety valves inside supplied kit. For schemes different
than 23, 24,25,26 or 27, safety valve must be defined by HVAC designer and have
to be in accordance with the local and European lows, standards and technical
norms. (Pnr = 0.8 МРа; EN 1489:2000). Valve dimensions acc. to Table.8
IMPORTANT: Between the storage tank and safety valve there must not be
any kind of stop valves or taps!
IMPORTANT: The presence of other /old/ safety valves may lead to a
breakdown of your appliance and they must be removed.
•
Safety valve drainage pipe. Must be implemented in accordance with the local
and European lows, standards and technical norms. It must have sufficient slope
for water runoff. Both ends should be open to the atmosphere and to be secured
against frost. Take safety measures against burning when safety valve is open!.

•
Water heater drainage.
•
Drainage tap.
•
Hose.
•
Expansion vessel. In the storage tank there is no volume to accommodate the
expansion of water due to its heating. The presence of the expansion vessel is
obligatory in order not to lose water through the pressure relief valve! Its volume
and type must be defined by HVAC designer and have to be in accordance with the
system technical requirements, local and European lows, standards and technical
norms. Its installation shall be carried out by a qualified technician in accordance
with its operating instructions. Reference data on the volume of expansion vessel
could be found in Table 9.
In order that you do not use the circulation outlet "R" and the outlets for the
temperature sensors "TS1" , TS2" and "TS3" as well as the outlet for the heating
element "EE" is necessary to put an end caps before filling the water heater with
water.
For models without heat exchanger – outlet marked with "AV" is intended for
connection of air vent device which allows removing the air from the water tank. For
long-lived service, it is advisory always to remove completely the air from the tank!
TO FILL UP THE STORAGE TANK is necessary to open the most distant tap,
used for supplying hot water in the installation (of the mixing-faucet) and the
tap (2) for supplying cold water near it. When the water heater is full, from the cold
water tap will continuously run water
IN THE EVENT YOU MUST EMPTY THE STORAGE TANK , first you must
cut off its power supplies if any. The inflow of water from the water mains must
first be terminated (tap 2) and the most distant hot water tap of the mixing- faucet
must be opened. Open the drainage tap (8) for full emptying of water tank!
IMPORTANT! All of the above mentioned rules for tank connection to water
mains are in relation of your safety! They comply with european and local
regulations and are obligatory!
Manufacturer assumes no responsibility for problems resulting from incorrect
assembly of the unit to the water supply net and because of using components with
unknown origin, not with compliance to the local and european standards!
CONNECTING THE SERPENTINES (HEAT EXCHANGERS) WITH
4.
HEATING INSTALLATION USING ALTERNATIVE AND RENEWABLE
SOURCES
ATTENTION! Qualified P&P specialist and technicians must perform all
assembly works for connection to the heat sources.
The connection of the serpentines (heat exchangers) with the heating installation
should be done considering the marked outlets and inlets as described below:
IS1 (MS) – Inlet of heat exchanger 1
OS1 (ES) –Outlet of heat exchanger 1
IS2 (M) –Inlet of heat exchanger 2
OS2 (E) - Outlet of heat exchanger 2
Make sure that the system is empty of air. The presence of air may cost incorrect
work of the boiler.
Maximum temperature of the heat transfer fluid: 110°C. Maximum pressure of the
heat transfer fluid: 0.8MPa!
A safety valve ((11) - Fig. 23, 24, 26,27) inline coil heat exchanger have to be fit
according to HVAC designer requirements but its adjustment must not be higher
than Pnr = 0.8MPa. (EN 1489:2000)

Instructions for use and maintenance
An expansion vessel according to HVAC Designer requirements must be installed!
It is recommended an installation of non-return valve (4). By this way, when
the external heat source is not working, your device will be preserved by
thermosyphon fluid circulation and associated heat loss from the tank!
I
MPORTANT! Manufacturer assumes no responsibility for problems resulting
from incorrect assembly of the heat exchangers to the additional heat
sources!
CONNECTING BUFFERS FOR DOMESTIC HOT WATER. EXAMPLES.
5.
The buffers for DHW are intended for domestic hot water accumulation with its
subsequent usage when there is a peak in the consumption!
As an example is shown Fig.26 for buffers.
ATTENTION! Connecting buffers DHW to the main water supply is shown on
Fig.26.

PROTECTION AGAINST CORROSION - MAGNESIUM ANODE
The magnesium anode protects the water tank's inner surface from corrosion.
The anode element is an element undergoing wear and is subject to periodic
replacementIn view of the long-term and accident free use of your water heater,
the manufacturer recommends periodic inspections of the magnesium anode's
condition by a qualified technician and replacement whenever required, and this
could be performed during the appliance's technical preventive maintenance.
(once per two years). For replacements, please contact the authorized service
stations!
VII.
OPERATING MODE
Before using the water heater make sure that the appliance is connected with the
heating installation in correct way and is filled with water.
VIII.
PERIODIC MAINTENANCE
At normal use of the appliance, under the influence of high temperature,
lime scaleis deposited upon the heating element's surface - (Fig.30/ Fig.31)
The manufacturer recommends preventive maintenance of your appliance
every two years by an authorized service center or service base. This protective
maintenance must include cleaning and inspection of the anode protector, which
shall be replace with a new one if need arises. Each preventive maintenance of
the said type must be entered in the appliance's warranty card and must outline
date of performing the preventive maintenance, name of person and company
performing the preventive maintenance, and signature.
Sign a contract for service and inspection with an authorized repair
specialist. It is recommended conducting maintenance once per year or
two depending on water quality.
THE MANUFACTURER DOES NOT BARE THE RESPONSIBILITY FOR ALL
CONSEQUENCES CAUSED BY NOT OBEYING THE INSTRUCTIONS, GIVEN
HEREBY.
IX.
INSTRUCTIONS FOR ENVIRONMENTAL PROTECTION
Old appliances contain valuable materials and because of this should
not be disposed with other products. To protect the environment we
kindly ask you to surrender them in approved centers only!
