Instructions
Please read these instructions carefully before installing and com-
missioning this unit. The manufacturer accepts no liability for loss
or damage resulting from failure to comply with these instructions
for use. Read and follow these instructions carefully to prevent the
risk of physical injury and/or damage to property. Exceeding the
recommended operating parameters appreciably increases the risk
of personal injury and/or damage to property.
Installation, commissioning and maintenance must be carried out
by quali ed and authorised personnel (both plumbing and electri-
cal work).
Once the system has been installed and is operating, there is normally
no need to alter the settings or other functions. The distribution sys-
tem unit is very reliable and easy to operate.
Heat source
The distribution system is primarily designed for connection to dis-
trict heating. Alternative energy sources can be used if the operating
conditions are equivalent to district heating at all times.
Application
The Danfoss stainless steel distribution systems are prefabricated solu-
tions for oor heating, which can be installed separately or be imple-
mented with the Danfoss at station range, in connection with a boiler
or as an extension of an existing heating system.
Choise of materials
Only use materials that comply with local regulations.
Storage
Before installation, the unit(s) must be stored in a dry, heated (i.e.
frostfree) room.
(Relative humidity max. 80 % and storage temp. 5 °C to 70 °C).
The units must not be stacked higher than the limit at the factory.
Units supplied in cardboard packaging must be lifted using the han-
dles incorporated in the packaging. Units must be placed on pallets
for transport/moving across large distances.
As far as possible, do not lift the unit by the pipes.
Retighten ALL pipe connections after transport/moving.
Disposal
Dispose of the packaging in accordance with the local regulations for
disposal of used packaging materials. The unit is made of materials
that cannot be disposed of together with household waste.
Close all energy sources and disconnect all connection pipes. Dis-
connect and dismantle the product for disposal in accordance with
the applicable local regulations for the disposal of the individual
components.
Connection
It must be possible to cut o all energy sources to the system – includ-
ing electrical connections – at all times.

Potential equalization/grounding
Potential equalization is an electrical equalizer connection to secure
against user contact with dangerous voltage, which may occur for
example between two piping systems. Potential equalization reduces
corrosion in heat exchangers, water heaters, district heating units and
plumbing installations. Equalization of potentials should be e ected
according to local regulations.
Warning! Hot surfaces
Parts of the unit may be very hot and can cause burn injuries.
Be very careful when you are in the immediate vicinity of the unit
Emergencies
In the event of re, leaks or other hazards, immediately shut o all
sources of energy to the unit, if possible, and call for appropriate
assistance.
If the domestic hot water is discoloured or malodorous, shut o all
ball valves on the unit notify all users and call for professional as-
sistance without delay.
Warning about damage during transport
On reception of the unit, and before installing it, check for any evi-
dence of damage during transport.
The unit must be handled and moved with the greatest care and
attention.
NB! - Tightening of connections
Before lling the unit with water, ALL pipe connections MUST be
retightened, as vibrations during transport may have caused leaks.
Once the unit has been lled and the system is hot, ALL pipe connec-
tions MUST be retightened once more. DO NOT OVERTIGHTEN THE
PIPE CONNECTIONS.
