General safety instructions

WARNING Burns
There is a risk of scalding at outlet temperatures in ex-
cess of 43 °C.
WARNING Injury
!
The appliance may be used by children over 8 years of
age and persons with reduced physical, sensory or men-
tal capabilities or a lack of experience and expertise,
provided that they are supervised or they have been
instructed on how to use the appliance safely and have
understood the potential risks. Children must never play
with the appliance. Children must never clean the ap-
pliance or perform user maintenance unless they are
supervised.
WARNING Injury
!
For safety reasons, only operate the appliance with the
front casing closed.
Note
The DHW cylinder is under supply pressure. During the
heat-up process, expansion water will drip from the safe-
ty valve.
f If water continues to drip when heating is complet- f
ed, please inform your qualified contractor.
Material losses
!
The system's active frost protection is not guaranteed if
the power supply is interrupted.
f Never interrupt the power supply even outside the f
heating season.

Appliance description

The buffer cylinder and DHW cylinder with indirect coil are ar-
ranged one above the other and can be separated for easier han-
dling.
The appliance has a plastic jacket with foam insulation and is
equipped with a removable front casing. The appliance is connect-
ed hydraulically and electrically to the heat pump. All hydraulic
connections are made at the top (heating) and rear (DHW).
In addition to the DHW cylinder and the buffer cylinder, further
system components are integrated:
- Highly efficient circulation pump for a heating circuit without
mixer
- 3/2-way diverter valve
- Cylinder charging pump (only in HSBC 300 cool)
DHW cylinders
The steel cylinder is coated on the inside with special direct enam-
el and is equipped with a signal anode. The anode with consump-
tion indicator protects the cylinder interior from corrosion.
The heating water heated by the heat pump is pumped through an
indirect coil inside the DHW cylinder. The heat channelled through
the indirect coil is thus transferred to the domestic hot water.
Buffer cylinder
The steel cylinder provides hydraulic separation between the flow
rates of heat pump and heating circuit. The heating water heat-
ed by the heat pump is transferred to the buffer cylinder by the
cylinder charging pump (only in HSBC 300 cool). When a demand
is issued, the integral heating circuit pump delivers the heating
water to the heating circuit.
