Safety notes
Authorised personnel
Assembly, installation, commissioning and maintenance must
only be carried out by a qualified and authorised HVAC or electrical
technician.
Read the instructions before start-up
The instructions must be read through before installation
and commissioning of the unit. Pay particular attention
to the section on safety precautions.
The manufacturer assumes no responsibility for failure to follow
the instructions. This applies to both personal injury and product
damage.
Installation requirements
The unit must be connected to the household installation
in a frost-free location.
Hanging and fastening
It must be ensured that both the wall and the fastenings
of the unit can bear the unit’s gross weight.
Heat source
The unit is designed for connection to heat network.
An alternative energy source can be used as long as the operating
conditions are equivalent to heat network at all times.
Handling
All lifting and handling of the heat interface unit must be carried
out in an ergonomically responsible manner.
Lifting the unit
When lifting the heat interface unit, only lift by the pipes that
are fixed to the back plate. Otherwise, to the extent possible,
the heat interface unit must be lifted by the back plate.
Please refer to the section “Lifting instructions”.
Re-tightening
As the unit has been subjected to vibrations during transport and
lifting/handling it is important that all union connections are re-
tightened.
After filling the system with water and once it is in operation,
all union connections must be re-tightened again.
Modifications
Modifications to the electrical connections on the heat interface
unit may only be carried out by an authorised electrician.
If changes are carried out to the heat interface unit’s configuration
or structure, the manufacturer can assume no responsibility.
Resistance to water on electrical equipment
Electrical components are not protected against water ingress.
Safety valve
A safety valve(s) must always be fitted in accordance with local
regulations.
Connection
The possibility to shut off all energy sources to the heat interface unit
at all times must be established, including the electrical connection.
It must be ensured that wires and cables do not come into contact
with the hot pipes. It must also be ensured that wires and cables are
not placed against sharp edges.
Warning of high pressure and temperatures
Particular attention must be given to the installation’s permitted
system pressure and operating temperature.
The maximum permitted flow temperature and pressure are stated
on the unit label.
The risk of personal injury or product damage increases considerably
if the recommended operational parameters are exceeded.
Warning of hot surfaces
Particular attention must be given to hot surfaces, as these can cause
burns to the skin.
Warning of sharp edges
It is recommended that suitable work gloves are used in connection
with handling and lifting of the heat interface unit.
