2. Safety
2.1 Intended use
This appliance is intended to be used for seasonal heating and
cooling of interiors and for DHW heating.
The appliance is intended for domestic use. It can be used safely
by untrained persons. The appliance can also be used in non-do-
mestic environments, e.g.in small businesses, as long as it is
used in the same way.
Any other use beyond that described shall be deemed inappro-
priate. Observation of these instructions and of the instructions
for any accessories used is also part of the correct use of this
appliance.
2.2 General safety instructions
WARNING Burns
There is a risk of scalding at outlet temperatures in ex-
cess of 109 °F (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. Cleaning and user maintenance must
not be carried out by children without supervision.
!
WARNING Injury
For safety reasons, only operate the appliance with the
front casing closed.
!
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
heating season.
Note
The DHW tank is under supply pressure. During the heat-
up process, expansion water will drip from the safety
valve.
f If water continues to drip when heating is complet-
ed, please inform your qualified contractor.

OPERATION
Appliance compatibility
ENGLISH
www.stiebel-eltron-usa.com HSBC 300 Integral | 5
3. Appliance compatibility
The appliance can be operated in conjunction with the following
air source heat pumps:
- WPL 15 A2W Premium
- WPL 25 A2W Premium
4. Appliance description
The buffer tank and DHW tank with indirect coil are arranged one
above the other and can be separated for easier handling.
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 & cooling) and rear
(DHW).
In addition to the DHW tank and the buffer tank, further system
components are integrated:
- Heat pump manager
- Highly efficient circulation pump for a heating circuit without
a mixer
- 3/2-way diverter valve
- Primary tank pump
DHW tank
The tank is steel and coated on the inside with a special direct
enamel and is equipped with a signal anode. The anode with
consumption indicator protects the tank interior from corrosion.
The heating water heated by the heat pump is pumped through
an indirect coil inside the DHW tank. The heat channeled through
the indirect coil is then transferred to the domestic hot water. The
integral heat pump manager (WPM) regulates the DHW heating to
the required temperature.
Buffer tank
This steel tank provides hydraulic separation between the flow
rates of heat pump and heating circuit. The heating water heated
by the heat pump is transferred into the buffer tank by the tank
charging pump. When a demand is issued, the integral heating
circuit pump delivers the heating water to the heating circuit.
Heat pump manager (WPM)
The system is controlled by means of the integral heat pump man-
ager.
Note
The heat pump manager has an automatic summer/win-
ter changeover so you can leave the system switched on
in summer.
fPlease observe the instructions for the heat pump manager.
5. Cleaning, care and maintenance
fHave the electrical safety of the appliance and the function
of the safety assembly regularly checked by a qualified
contractor.
fNever use abrasive or corrosive cleaning agents. A damp
cloth is sufficient for cleaning the unit.
Signal anode with consumption indicator
!Material losses
If the consumption indicator changes color from white to
red, have the signal anode checked by a qualified con-
tractor and if necessary replaced.

1 White = Anode OK
2 Red = Requires checking by qualified contractor
6. Troubleshooting
Problem Cause Solution
The water does not heat
up. The heating does not
work.
There is no power. Check to ensure circuit
breaker in breaker panel
hasn’t tripped. Reset if
necessary.
If you cannot solve the problem, contact your qualified contractor.
To facilitate and speed up your inquiry, please provide the serial
number from the type plate (000000-0000-000000).

9. Preparation
9.1 Installation site
!Material losses
Never install the appliance in wet rooms.
Install the appliance near the draw-off point in a dry room free
from the risk of frost. To reduce line losses, keep the distance short
between the appliance and the heat pump.
Ensure the floor has sufficient load bearing capacity and evenness
(for weight, see chapter "Specification/ Data table").
The room must not be subject to a risk of explosions arising from
dust, gases or vapors.
If you are installing the appliance in a boiler room together with
other heating equipment, ensure that the operation of the other
heating equipment will not be impaired.
