INSTALLATION
Preparation
8 | HPG-I (C)S Premium www.stiebel-eltron.com
The room in which the appliance is to be installed must meet the
following conditions:
- No risk from frost
- The room must not be subject to a risk of explosions arising
from dust, gases or vapours.
- When installing the appliance in a boiler room together with
other heating equipment, ensure that the operation of other
heating equipment will not be impaired.
- The minimum volume of the installation room must be ob-
served (see chapter "Preparation/ Safety concept").
- Load bearing floor (for the weight of the appliance, see chap-
ter "Specification/ Data table").
f Ensure that the safety valve for the brine circuit is installed
in the installation room. Alternatively, outdoor installation is
also possible.
f Ensure that the substrate is level, even, solid and permanent.
f For installation on floating screeds, make provisions for quiet
heat pump operation.
f Isolate the installation surface around the heat pump by
means of a recess. After completing the installation, seal the
recess with a waterproof, sound insulating material, suchas
silicone.

f Maintain the minimum clearances to ensure trouble-free op-
eration of the appliance and facilitate maintenance work.
8.4 Electrical installation
WARNING Electrocution
Carry out all electrical connection and installation work
in accordance with national and regional regulations.
WARNING Electrocution
The connection to the power supply must be in the form
of a permanent connection. Ensure the appliance can be
separated from the power supply by an isolator that dis-
connects all poles with at least 3mm contact separation.
This requirement can be met by using contactors, circuit
breakers, fuses/MCBs, etc.
!
Material losses
Provide separate fuses/MCBs for the two power circuits,
i.e. for the compressor and the electricemergency/boost-
er heater circuits.
Note
The specified voltage must match the mains voltage. Ob-
serve the type plate.
Note
The appliance includes an inverter for the variable speed
compressor. In the event of an error, inverters can cause
DC residual currents. If RCDs are provided, they must be
type B AC/DC-sensitive.
A DC residual current can block type A RCDs.
f Ensure that the appliance power supply is discon-
nected from the distribution board.
