For this aim within their structure is mounted a fuse to prevent that the system reaches a higher
than acceptable pressure.
The heat pump heaters are intended to heat water not only with their heat pump system, but
as well with 2 000 W electric heater. It is possible to heat water only with the appliance electric
heating element.
WATER HEATERS WITH SOLAR HEAT EXCHANGERS
These models water heaters provide the opportunity to save electricity thanks to the
integrated heat exchanger. When operating the latter allows heating the water volume from
alternative heat source such as a solar collector. It is necessary to use within the system a heat
transfer fluid not exceeding 85°
С
.
WARNING!
IT IS ABSOLUTELY FORBIDDEN to allow heat transfer fluid circulation through
the heat exchanger when the water tank is empty. IT IS ABSOLUTELY FORBIDDEN to close
simultaneously the heat exchanger inlet and outlet.
For heat transfer fluid always use a solution of propylene glycol diluted with water in a ratio
consistent with environmental climatic conditions. Installation and connection of the water
heater heat exchanger to it must be carried out only by qualified and licensed companies with
same business in accordance with specific project.
INSTALLING THE WATER HEATER (INDOOR UNIT) TO THE WALL
The water heater (indoor unit) may be installed only in premises with regular fire safety and
where temperature may never drop below 0°
С
. It is necessary as well that the floor in the
premise be equipped with trap for wastewater, as it is possible during normal operation from the
relief valve outlet from time to time to drip water. The wastewater trap shall ease maintenance,
prevention and service operations for the water heater requiring drain of tank water.
The place for installation of the water heater must comply with its dimensions, way of
mounting, and location of fixing elements and pipes and its waterproof class of protection. The
latter is noted on the appliance plate serial number. It is absolutely necessary that the appliance
is protected from dripping or spraying with water.
Water heater must be rigidly mounted to the premise wall. For the purpose apply firmly
fastened in the wall steel bolts (pins) of 10-12 mm diameter. The fasteners must be secured
against pulling out of the wall, i.e. these must be anchor bolts or bolts passing through the wall
section (depending of wall material). It is not allowed to mount the water heater on decorative
walls (of single bricks or lightweight materials).
