2. Safety
2.2 Safety instructions
Observe the following safety instructions and regulations.
Heat pump systems and accessories may only be installed by a
recognised specialised company.
The qualified technician is responsible for observing all applicable
regulations during installation and commissioning.
Only operate the device when it is fully installed with all its safety
equipment.
Beware of electrocution
Switch off the power supply immediately if cables are
damaged. Make sure it is secured against being switched
on again unintentionally.
Beware of electrocution
Make sure all cable entries are fitted with the appropriate protection class.
Beware of burns and scalding
Before working on the system, let the pipes on the relevant section cool down as necessary and reduce the
system pressure to ambient pressure.
Beware of injury
The appliance may be used by children aged 8 and up
and persons with reduced physical, sensory or mental
capabilities or a lack of experience provided that they
are supervised or they have been instructed on how to
use the appliance safely and have understood the resulting risks. Children must never play with the appliance.
Children must never clean the appliance or perform user
maintenance unless they are supervised.
Beware of damage
The 3-way switching valve is designed for use in STIEBEL
ELTRON or Tecalor heat pump systems and may not be
used for applications outside the stated range, particularly in aircraft or other means of transport.
2.1 Proper use
The 3-way switching valve distributes and regulates the flow in
STIEBEL ELTRON or Tecalor heat pump systems. Any different or
extended use is considered improper, especially use with other
media to be heated. Proper use also includes observing the installation instructions. Only use the device for the purpose stated by
the manufacturer and do not make any modifications to it.
This appliance is designed for domestic use. It can be used safely
by untrained persons. The appliance can also be used in a nondomestic environment, e.g. in a small business, as long as it is
used in the same way.

DEVICE DESCRIPTION
3.3 Function
The 3-way switching valve is controlled using a servo or
lift drive.
Note
As well as the flow direction A – AB and B – AB which
is marked with an arrow on the housing, the opposite
direction AB – A and AB – B is also permitted in STIEBEL
ELTRON or Tecalor heat pump systems.

HUV 1 | HUV 2 only: The servo drive is constantly regulated by a
control system and moves the ball of the 3-way switching valve,
that acts as a restrictor, to the position specified by the actuator
signal. The valve opens by turning clockwise and closes by turning
anticlockwise (factory setting).
HUV 65 | HUV 80 only: The lift drives are regulated by a 3-point
control system and move the closing element, which acts as a
mixer, to the opening position defined by the actuator signal.

4.1 Installation position
The 3-way switching valves can be installed either vertically or
horizontally.
Beware of damage
!
The 3-way switching valves may not be installed suspended, i.e. with the tappet facing down.
Permissible installation positions
90° 90°
C26_03_01_0997
4.2 Hydraulic connection
Beware of damage
The conditions in VDI 2035 regarding water quality must
be complied with. So that the 3-way switching valve controls the flow for a long time, we recommend the use of
contamination filters.
Beware of damage
Make sure the ball is correctly positioned in
the 3-way switching valve (note the mark on
the spindle).

Beware of burns and scalding
Let the pipes on the relevant section cool down as necessary and reduce the system pressure to ambient pressure.
Beware of damage
Switch off the pumps for the relevant pipe section and
close the associated shut-off valves.
The system may only be started up again once the 3-way switching
valves with integrated servo drive have been correctly fitted and
the pipes correctly filled.
