Storage tanks are delivered on an individual transport pallet. If the high capacity
water heaters are used in premises with low humidity and flat floor you can leave
the pallet as it is mount on the appliance, otherwise – please follow the described
steps bellow (Fig. 5):

Put the appliance in horizontal position;
Unscrew the three bolts which hold the pallet to the water heater;
Mount the adjustable feet directly to the appliance;*
Put the storage tank in vertical position and adjust the level using the feet.
*If the adjustment feet are delivered in separate parts you can assemble them as
follow (Fig. 6):
put the part 1 on bolt 2 which is unscrewed from the pallet
put the washer 3 which is removed from the pallet
Screw on the nuts 4 which are delivered with the appliances

ATTENTION! In order to prevent injury to user and/or third persons in the
event of faults in the system for providing hot water, the appliance must be
mounted in premises outfitted with floor hydro insulation (or) plumbing drainage.

2. MOUNTING OF “SOFT” PU INSULATION (800-2000L)

For the installation of insulating material two persons, in the case of very big
boiler, three persons are needed. The temperature of the room where the fitting
takes place should be at least 18°C. The insulation set should be stored at above
mentioned temperature at least one hour before operating!
In the next step both sides of the zipper have to be pulled with light traction into
the direction of the arrows shown in FIG.11. Please take care that the prefabricated
holes stay in place and the connections are accessible all the time.
It is important to make sure that both sides of the zipper do not remain more than
20mm apart from each other after being fitted (Fig.11). Now push both sides of the
zipper to the boiler and fix them on the first position. If necessary, the insulation
can be narrowed (Fig.11) down again.
Once the insulation material has been fitted correctly and fastened with the zipper,
the foamed material is inlayed and closed with a plastic lid on the top. Finally,
rosettes can be fixed onto the connections (Fig.11).
The insulating set should only be stored in a dry place! We cannot be held
responsible for damage because of failure to observe these instructions!

3. CONNECTING THE SYSTEM TO THE MAIN WATER SUPPLY NETWORK

IMPORTANT! Connecting the water heater 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.8. Installation of the storage tank with two heat exchangers should be
done in accordance with Fig.7; Fig.12. Models without heat exchangers – the
same as for models with one or two heat exchangers. Parallel installation acc. to
Fig.9.

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 7, 8, 9,12 or 13, 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.4

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!.
Fig.10 a, b, c.
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 5.

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!

4. CONNECTING THE SERPENTINES (HEAT EXCHANGERS) WITH

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. 7, 8, 9, 12) 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)
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!

IMPORTANT! Manufacturer assumes no responsibility for problems resulting
from incorrect assembly of the heat exchangers to the additional heat
sources!

VI. 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. The manufacturer
recommends preventive maintenance of your appliance every two years by
an authorized service center or service base – (Fig.30 / Fig.31).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.
