Accessories
Important notice: please note that below given accessories or fittings are not supplied with the tank
package. Necessary accessories and fittings must be supplied seperately to continue guarantee
coverage.
Safety accessories:
Safety and control equipments should be installed and operated according to parts mentioned below
in order to limit the domestic water temperature maximum 95°C

4
• Thermostatic control device
• Energy cut-off device (safety cut-off functioned thermostat)
• Temperature reducing valve, pressure reducing valve or safety relief valve
All equipments which are necessary to limit the water temperature under 95°C, must compliant with
the local regulations.
Safety Valve : In case of high pressure in the tank, discharges the overpressure.
Expansion Vessel : Absorbs pressure fluctuations that may occur in the system.
One-way Valve : Allows fluid moving inside the system on desired direction and avoids the flow back
to the opposite direction.
Filter : Used to block dirts from the water.
Valve : Used to allow or stop the flow of domestic water into the system
Pump : Enables the circulation of fluid used in the system.
Manometer : Used to measure the pressure of the system.
Thermometer : Used to measure the temperature of the liquid in the system.
Pressure Reducer : In case the water pressure in the system exceeds the allowed pressure of the
device, an appropriate pressure reducer must be installed to decrease the pressure of water.

Recommendations
Warning: THE MOST IMPORTANT POINT IS INSTALLING THE SAFETY VALVE, DURING INSTALLATION OF
A WATER HEATER TANK.
Domestic water inside the tank expands when it is heated. The expansion rate of water according to
the temperature is given at the chart below. E.g. water expands 2,88% at 80˚C. This extra volume of
water should be removed from the water heater tank as water is incompressible. If the expanded
water is not removed from the tank, this will increase pressure inside the tank which can cause
damages on the weakest point of the tank.

Expansion Tank Installation
There must be a closed membrane type proper expansion tank installed in the system together with
wter heater tank. It should be selected as minimum 10% volume of the water heater tank volume. E.g.
together with a 1000 lt water heater tank, a 100 lt expansion tank must be installed in the system.
Expansion tank can be used under 8 bar pressure and initial pressure should be set to %10 lower then
the operation pressure. The most important protection precaution is to install a proper safety valve
and expansion tank in the system. Always install the expansion tank and the safety valve between the
water heater tank domestic cold water inlet and the valve of the main water line.
Before Commissioning
• Tank must be installed by a qualified staff by taking all safety measures and precautions
according to the local and general regulations.
• The domestic water used in the system must conform standards defined in the last page
of this manual. The warranty does not cover cases where the domestic water does not
conform these standards.
• Make sure that all hydraulic and electrical connections are done properly.
• Check all hydraulic connections against leakage.
• Make sure to take precautions against leak, electric shock, damages because of the
movement of tank, etc.
• If an electric heater installed, it must be grounded. While working on electric connections
take all measures and cut the electric current to avoid injuries or risk of death because of
electric shock.
Commissioning
• Make sure that water heater is completely filled with water before start operation of your
water heater and cold water inlet must be connected to main water supply continuously.
• After completely filling the tank with water, in order to release remaining air inside the
tank, open the domestic hot water tap.
• Electric connections of the device must be done by a qualified electrician.

8
• Check the cable cutaway, voltage value and grounding and then set the regulation
thermostat if available.
• Do not turn on the electric heater before completely filling the water heater tank,
otherwise electrical heater will blow and damage as produced just inside the water.
• It is important to install a residual current device to the power supply when you use
electrical products on the tank.
BSX Heat Pump Single Coil Tanks Installation
Important notice: maximum 8 bar safety valve must be installed.
Maintenance
• It is suggested to clean inside the water heater through the cleaning flange in order to
remove dirts that may exist in the water.
• If the product have electrical heater or instruments, please disconnect all electric
connections and turn-off completely before any maintenance or cleaning operation.
• Gaskets on the product will be damaged after removing them. In case they are removed
for any reason, they should be replaced with a new one.
• Cleaning the device by chemicals is not recommended. Hazardous chemicals will damage
the enamel coating and also harmful to human health if not well cleaned.
• Please be sure that the accessories e.g. valves, one-way valve, strainer, safety valves,
expansion tank and thermometer are in always in operation, to avoid any damage on tank
and system.
• Please remove and clean the filter of the strainer periodically.
• The magnesium anode bar should be checked annually. The substitution frequency can be
determined after the first check. The quality and contaminents of water is important for
the life of the anode.
• If the magnesium anode bar diameter is less than 12 mm it should be replaced with a new
one with a minimum diameter of 26 mm.
• The magnesium anode bar is a sacrificial part therefore it is out of warranty.
• Tanks operated without magnesium anode bar or operated with magnesium anode bar
less than 12 mm are out of warranty.
• When the water heater tank is out of operation, please be sure that the water discharged
completely and tank is empty to protect the tank against freezing.

9
• While cleaning the interior of the tank, please be sure about not damaging the enamel
coating inside.
• After cleaning the interior of the tank, please be sure that flange, sensor(s) and
thermostat connections are not leaking.
Checklist For Troubleshooting
Problem: electrical heater (optional) is not working;
Possible reasons:
• Electric connection might be not connected,
• The switch might be off,
• The building’s main fuse might be switched off.
Problem: no domestic hot water at the tap;
Possible reasons:
• The hot-cold water valve might be turned-off.
• Main water supply might be off
• The strainer might be blocked and out of order.
Problem: domestic water at the hot side of the tap is not hot;
Possible reasons:
• Heating system or solar collector loop might be out of order,
• Circulation pump might be switched-off or out of order.
Problem: there is not enough hot water supply from the water heater tank;
Possible reasons:
• The tank/system capacity might not be adequately selected,
• The hot water might return back to the system if a one-way valve is not being used,
• There might be a problem with the controller.
Problem: safety valve on water heater is leaking;
Possible reasons:
• The main water line pressure might be above 6 bar,
• Safety valve gasket might be blocked and remain open because of dirt/limescale.
