General Information - Samsung RC090MHXEA Installation Manual

General information

f SAMSUNG Eco Heating system with cylinder unit is designed to withstand SAMSUNG durability and reliability
requirements. We cannot guarantee neither good operation nor reliability of total system with other brand tanks.
f The piping, valves and system configuration of cylinder unit should be followed a relevant local or national regulations.
f A pressure relief valve in accordance with an opening pressure of max. 0.9MPa should be connected.
f The electrical box must be opened by a licensed electrician.
f Switch off the power supply before opening the electrical box lid.
f Make sure that the installation location of cylinder unit including piping and valves is frost free.
f Please leave this manual with the end user after installation
f All cylinders are manufactured in accordance with the requirements of BS EN 12897. The tundish must be positioned so
that it is visible to the occupant and is away from electrical devices.
Heat pump system application
f The Cylinder is an unvented hot water storage cylinder fitted with a high efficiency internal primary heat exchanger
especially designed for use with heat pump systems.
f All Cylinder models are fitted with 3kW (240Vac, 50Hz) immersion heater for raising the temperature of the stored water
to about 60°C after the heat pump heating cycle if necessary.
f Heat pumps can normally only heat the domestic hot water to between 45 – 55°C, therefore provision should be made to
periodically heat the cylinder to about 65°C to prevent growth of legionella.
• Cylinder unit shall be located and installed indoors (garage, multipurpose room, boiler room).
• Always ensure that the ambient temperature around unit have to be above 0°C around the year.
CAUTION
• If the unit and the pipes are exposed to freezing temperature, It can cause damage to the hydraulic system.
Special care must be taken to prevent freezing of the total water system.
• If the unit stops for a long time because of a power supply failure, pump operating failure, or winter vacation,
drain all water from the system.
• Cylinder unit shall be always full of water. Check that water is fully filled with water by opening the pressure relief
valve. Air present in the water system may cause malfunction or fire.
• Water quality must be according to EN directive 98/83 EC.
• Make certain that back flow preventer (check valves) must be installed on main supply line to prevent from
contaminating the city water. It is recommended to install the make-up water assembly to prevent from
contaminating the city water. Check valves in the make-up water assembly can prevent running water inside
hydro unit from contaminating water supplies during installation or maintenance works.
• Before running the cylinder unit, check if valves are opened for inlet and outlet port of water pumps. And make
sure to have direction of valve slot be straight in horizontal.
