The ATTACK, s.r.o. company is the largest manufacturer of the accumulation tanks in Slovakia
with the widest offer of these items.
1. GENERAL INFORMATION
This instruction manual is an inseparable and important part of the product. Read the instruc-
tions given in this manual carefully, as they contain important information about safety, installa-
tion, usage and maintenance. Keep this manual to be eventually used in future. This appliance is
constructed for accumulation and subsequent distribution of the heat energy from the heat sourc-
es as well as for preparation of the D.H.W.
It is forbidden to use this appliance for other purposes than given above (e.g. as a D.H.W.
tank), except of the tanks with a built-in D.H.W. tank. Producer takes no responsibility for
damages caused by unsuitable or incorrect usage.
Before starting the work on device or its maintenance, disconnect the electrical power inlet. If
there are any marks of fault on the appliance, stop the operation and call a service technician.
2. DESCRIPTION OF DEVICE
The tanks serve for accumulation and subsequent distribution of the heat energy from solid fuel boil-
ers, heat pumps, electric boilers, etc. The accumulation tanks ATTACK AS, HRS, TUVS and SS are acces-
sorized with an extra exchanger for a heat source with separated circuit (e.g. for solar system). The accu-
mulation tanks ATTACK HR, HRS, TUV, TUVS are equipped with a built-in system for D.H.W. preparation.

ACCUMULATION TANKS
DESCRIPTION
The accumulation tanks ATTACK HR, HRS are made from the quality steel
and serve for accumulation of the heating water as well as for preparation of
the D.H.W. by an internal enameled exchanger. The ATTACK HRS model is
accessorized with an extra exchanger to be connected to the solar system.
Tanks of this type have a built-in magnesium anode in the D.H.W. tank
to increase resistance against corrosion. The manual deaeration valve is in-
stalled in the upper part.

4. OPERATION
Tanks accumulate heat from the heating systems for domestic or industrial use. Different types of
boilers and heating systems, renewable energy sources (heat pumps, sun collectors) or electricity
can be used to heat the water in the accumulation tank.
Heat in the tank is accumulated either by flow of the heating liquid from the heat source or by
flow of the heating liquid and the heat transfer (e.g. from solar system) through the tubular ex-
changer, or by warming by the electrical bodies installed inside the tank.
In the built-in D.H.W. tank or built-in instantaneous D.H.W. warming is the warmth accumulated
from the water in the accumulation tank.
5. INSTALLATION
The installation must be in conformity with the valid regulation and it can be done only by
a qualified specialist.
Faults caused by the incorrect installation, usage and operation cannot be considered as a war-
ranty case.
5.1 CONNECTION TO THE HEAT SOURCE
Place the accumulation tank on the ground, as close as possible to the heat source. Install the insu-
lation. Connect the heating circuits to all inlets and outlets as it is given in the table in the chapter 3.
Mount the deaeration valve at the highest place of the system and insulate all the connection
distributions.
5.2 CONNECTION OF THE ELECTRICAL HEATING BODIES
The accumulation tank can be accessorized with the electrical heating bodies. The electrical
heating bodies can be connected to the electricity mains directly (body with an own thermostat)
or through the regulator of the whole heating system.
6. PUTTING INTO THE OPERATION
Fill the heating circuits with the appropriate liquids and deaerate the whole system. Check the
tightness of all the joints and the pressure in the system.
CAUTION: Accumulation tanks HR/HRS are filling as follow. The first, will be filled inside
tank and then remainder of accumulation tank. In case of nonobservance of process the
inside tank can be damaged.
Set the parameters of the regulation of the heating system as it is given in the documentation and rec-
ommended by the producer. Check the correct function of all control and regulation elements regularly.
Quality of the heating water significantly influences the lifetime of the heating systems. Unsuitable
quality of water may cause problems like the corrosion of device and creation of the limescale, especially

13
ACCUMULATION TANKS
on the heat-exchange surfaces of device. Quality of the heating water depends on the quality of the
water filled into the system by starting the operation and quality and amount of the water additionally
filled into the system. Quality of the water additionally filled into the system is defined in the STN 07 7401.
To prepare the D.H.W. in a built-in tank or an instantaneous system, it is necessary to install the
safety valve of 6 bar on the cold water inlet. It is also necessary to ensure the treatment of the
D.H.W. against the limescale and dirts from the water distribution network.
Hardness of water cannot exceed 5 mval / l. Warranty does not relate to the blockage of the tank
or the flow copper exchanger by a limescale.
7. MAINTENANCE
To clean the external parts of the tank you need a wet cloth and a suitable detergent. Never use
abrasive cleaners, diluents, petroleum-based cleaners, etc.
Check the tightness of joints on the flange of the HR, HRS tank at least once a year, eventually
fix the nuts. If there is untightness even after fixing the nuts, replace the sealing under the flange.
Maintenance of the accumulation tank HR, HRS concerns test and replacement of the anode rod.
The magnesium anode adjusts the electric potential inside the tank to the value preventing cor-
rosion of the tank. Theoretical life-time of the anode takes 2 years of operation, but it changes ac-
cording to the callosity and the chemical composition of water at the place, where the tank is used.
It is recommended to make a test every 6 months and in the case of need, to replace the anode rod.
This additional protection element should be considered as important.
Procedure of replacement of the anode rod:
1. Discharge approximately 1/3 of the water in the tank
Procedure: close the valve at the water inlet into the tank,
open the valve of hot water on the mixing tap,
open the discharge valve of the tank.
2. Undo the upper cover of the accumulation tank.
3. Use a suitable tool to screw the anode out.
4. Install a new anode and mount the dismantled parts back.
5. Fill the tank with water, pressurize it and check the tightness.
The anode must be replaced only by a specialized service company!
8. DISPOSAL
Packaging must be disposed following the valid prescriptions.
After expiration of the lifetime it is necessary to dispose the product in conformity with the legal
prescriptions.

SPECIFICATION OF THE ANNUAL CHECKS OF THE ACCUMULATION TANKS
(performed by the authorized service)
1. CHECK OF THE STATE OF THE TANK
The accumulation tank does not need a maintenance indeed, it is only necessary to make a check
of the pressure and tightness of all the joints. In case of the water leakage from the tank or leakage
of the liquid from the heating circuits, stop the operation of device and seal the joints to ensure the
stated operating conditions.
2. CLEANING AND MAINTENANCE OF THE TANK
To clean the external parts, use a wet cloth and a suitable detergent. Never use abrasive cleaners,
diluents, petroleum-based cleaners, etc.
It is not necessary to clean the internal side of the tank, because it is connected to the closed
heating circuit with a permanent filling.
3. ELECTRICAL HEATING BODIES IF THEY ARE CONNECTED
If there are electrical heating bodies installed in the tank, it is necessary to make a check of the
function of thermostats, state of the contacts and fixation of the screws of all terminals.
