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 physi-
cal 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 qualified and authorised personnel (both plumbing and electrical
work).
Once the system has been installed and is operating, there is normally
no need to alter the settings or other functions. The distribution system
unit is very reliable and easy to operate.
Heat source
The distribution system is primarily designed for connection to district
heating. Alternative energy sources can be used if the operating condi-
tions are equivalent to district heating at all times.
Application
The Danfoss stainless steel distribution systems for multi family houses
are prefabricated distribution units with incoorporated metering
station. The distribution systems serve to distribute floor heating and
the metering stations serve to measure the heating consumption,
typically for each single apartment in an apartment block.
Choise of materials
Only use materials that comply with local regulations.
Corrosion
The maximum chlorine content of the medium must not be higher
than 300 mg/l. The risk of corrosion increases considerably if the rec-
ommended chlorine content is exceeded.
Storage
Before installation, the unit(s) must be stored in a dry, heated (i.e.
frostfree) room.
(Relative humidity max. 80% and storage temp. 5–70°C).
The units must not be stacked higher than the limit at the factory. Units
supplied in cardboard packaging must be lifted using the handles
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. Discon-
nect and dismantle the product for disposal in accordance with the ap-
plicable local regulations for the disposal of the individual components.
Connection
It must be possible to cut off 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 re-
duces corrosion in heat exchangers, water heaters, district heating
units and plumbing installations.
Potential bonding should be carried out according to 60364-4-41:
2007 and IEC 60364-5-54: 2011.
Bonding poing is marked on the mounting plate below right corner
with an earthing symbol and there will be a hole in the station
mounting plate and a label with earth symbol.
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 fire, leaks or other hazards, immediately shut off all
sources of energy to the unit, if possible, and call for appropriate
assistance.
If the domestic hot water is discoloured or malodorous, shut off
all ball valves on the unit notify all users and call for professional
assistance 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 filling the unit with water, ALL pipe connections MUST be
retightened, as vibrations during transport may have caused leaks.
Once the unit has been filled and the system is hot, ALL pipe connec-
tions MUST be retightened once more.
DO NOT OVERTIGHTEN THE
PIPE CONNECTIONS
.
Handling
We recommend that you wear suitable safety footwear while
handling and installing the unit.
