2.0 Safety notes
Instructions
This operating manual should be read carefully before installation and
start-up of the substation. The manufacturer accepts no liability for
damage or faults that result from non-compliance with the operating
manual.
Please read and follow all the instructions carefully to prevent accidents, injury and damage to property. The risk of persons being injured
and equipment damaged increases considerably if the recommended
permissible operating parameters are exceeded.
Installation, assembly work, first start-up and maintenance work may
be carried out only by qualified and authorized personnel in compliance with the safety regulations (both heating and electrical work).
Connection
The substation must be equipped with features that ensure that
the substation can be separated from all energy sources (also
power supply).
Warning of hot surfaces
Parts of the substation may become hot and hot surfaces can
cause serious burns. Please be extremely cautious in close proximi-ty to the substation.
Energy source
The substation is designed for district heating as the primary source
of energy. However, also other energy sources can be used where the
operating conditions allow it and always are comparable to district
heating.
Application
The substation is designed only to operate with water or a water-glycol
mixture (up to 40%), and other heating media may not be used.
Connect the substation to the house installation in a frost-free room,
where the temperature does not exceed 50 °C and the humidity does
not exceed 60%. Do not cover or wall up the substation or in any other
way block the entrance to the station.
Choice of material
Choice of materials always in compliance with local legislation.
Corrosion protection
The maximum chloride compounds of the flow medium should not
be higher than 300 mg/l. The risk of equipment corrosion increases
considerably if the recommended permissible chloride compounds
are exceeded.
Safety valve(s)
We recommend mounting of safety valve(s), however, always in compliance with local regulations.
Sound level.
≤ 55 dB.
Warning of high pressure and high temperature
The stations work at a maximum supply temperature from the
district heating network of 120°C and the stations work with a operating pressure of 16 bar, which may put the user at risk of burns
from touching the surface or from the emissions of hot media
(water/steam). The risk of persons being injured and equipment
damaged increases considerably if the recommended permissible
operating parameters are exceeded.
Emergency
In case of danger or accidents - fire, leaks or other dangerous circumstances - interrupt all energy sources to the station if possible,
and seek expert help.
In case of discoloured or bad-smelling domestic hot water, close
all shut-off valves on the substation, inform the operating personnel and call for expert help immediately.
Warning of transport damage
Before substation installation, please make sure that the substation has not been damaged during transport. Always transport
the substation with the utmost care and caution.
IMPORTANT - Tightening of connections
Due to vibrations during transport all flange connections, screw
joints and electrical clamp and screw connections must be checked and tightened before water is added to the system.
After water has been added to the system and the system has
been put into operation, re-tighten ALL connections.
(Do not overstrain! - See item 7.7)
3.0 Storage and Handling
If the substation is stored before installation, make sure that the place
is dry and heated.
(Humidity max. 60% and storage temperature 5-70 °C).
Do not stack the unit higher than factory shipped. Units that are
shipped in cardboard packaging are to be lifted by the carrying
handles of the packaging. Transport / removals over great distances
should be carried out on pallets.
During and after unpacking, the substation can be lifted by using
straps, fitted around the pipes or it can be lifted by hand in the
pipes Lifting in the pipes can cause leaks. ALWAYS re-tighten.
Handling
When working on the substation suitable safety shoes must be
worn.
4.0 Disposal
Dispose of packaging material in accordance with local regulations.
This product consists of materials, which must not be disposed of
together with domestic waste. Switch off the complete power supply and dismantle the product and sort the components in various
groups before disposal. Always observe the disposal rules of the local
legislation.

The temperature for the heating circuit is controlled by the
Danfoss ECL controller in combination with an electronic actuator.
The supply temperature is calculated by the controller on basis of
the outdoor temperature.
For variants with Danfoss ECL 300 the domestic hot water temperature is also controlled by an electrical actuator in combination with the electronic controller, incl. of an immersion sensor for
mounting in the DHW cylinder.
Please note:
Your substation may look different than the substation shown, as
variants with other components may be supplied.
Instructions for the fitted components will always be supplied together with the substation.

12.3.1 Differential pressure controller
The self-acting differential pressure controller AVP-F reduces the
fluctuating pressure in the district heating network to a small
and invariable operating pressure in the substation and thereby
ensures the best possible operating conditions.
The control valve opens on falling differential pressure to maintain constant differential pressure, and closes on rising differential
pressure.
The differential pressure controller is preset from factory and
should not be adjusted afterwards.

13.0 Circulation pump
The Kompakt H substations come standard with Wilo circulation pumps.
Alternatively Grundfos pumps may be used. The Wilo Wilo installation
and operating instructions will in such cases be replaced by Grundfos
installation and operating instructions.
Substation start-up / pump
Do not start up the pump until the system has been filled with the
flow media and vented.
On traditional heating systems the selector switch (the red button)
must be turned left for selection of constant pump operating mode.
It is recommended to set the pump at highest speed of rotation before start-up. Then set the pump at lowest possible speed of rotation,
in due consideration of the electricity consumption and the heating
comfort. (The factory setting of the selector switch, “the red button”
does not comply with the flow rate required for the system)
Floor heating
Select variable pump control mode for floor heating. Turn the red but-
ton to the right.
Set the pump at lowest possible speed of rotation, in due consideration
of the electricity consumption and the heating comfort.
Summer operation
The circulation pump for heating is automatically switched off in periods without heat demand. To prevent the pump from blocking in
periods without heat demand, the controller automatically switches
on the pump for some minutes every third day. In this period the
circulation pump should be set at the highest speed of rotation.
The shut-off valve/summer valve S in top of the station can be closed
during this period. It is recommendable to vent the system after the
summer period.
If the heating requirement increases the pump setting can be changed
by means of the selector switch
S
For more information about venting of pump etc. please refer to enclosed installation and operating instructions:

13.1 Alternative Circulation pump Grundfos Magna 25-100
For systems with Grundfos circulation pumps please follow the enclosed Grundfoss Installation and Operating Instructions for setting
of pump.
In general, Grundfos recommends:
• AUTOADAPT (factory setting)
(This control mode is suitable for most installation. During operation, the pump auto matically reduces the factory-set setpoint and adjusts it to the actual system characte ristic).
• Proportional-pressure control (systems with relatively large pressure losses).
• Constant-pressure control (systems with relatively small pressure losses).
• Automatic night-time duty
Please note that the system can not be vented through the pump.

15.0 Maintenance
Maintenance work
Is only to be carried out by qualified and authorised personnel.
Inspection
The operator or other authorised personnel is obliged to perform inspections at regular intervals and if necessary carry out maintenance
work according to these and other instructions. Within the scope of the
above maintenance work all strainers should be cleaned, all connections
should be tightened and the operation of the safety valves should be
checked by turning the valve head in the indicated direction.
Rinsing/cleaning of plate heat exchanger
Brazed heat exchangers can be rinsed. For optimum cleaning the flow
rate should be a min. of 1.5 times normal flow rate, preferably in backflush mode. This will remove any deposits formed on the inside of the
plate heat exchanger. In case of more serious deposits, a cleaning liquid,
approved by Danfoss (f.ex. Kaloxi or Radiner FI) can be pumped through
the heat exchanger. Both are environmentally friendly cleaning fluids
and can be disposed of through the usual domestic sewerage system.
Afterwards rinse thoroughly with large amounts of water.
Deacidification of plate heat exchanger
After long operation, because of the relatively high temperatures in
the plates or tubes, the heat exchangers are expecially subject to
calification. Any deacidification of the plate heat exchanger is done as
shown on the drawing to the right. For brazed plate heat exchangers
weak inhibited acid solutions (e.g. 5% formic, acetic or phosphoric acid)
may be used.
Measures after maintenance work
After maintenance work and before switching the system on again:
– Check that all screwed connections are tight.
– Check that all safety features, covers, that were removed, have been
replaced properly.
– Clean the working area and remove any spilled materials.
– Make sure that all tools, materials and other quipment that were
used, have been removed from the working area.
– Connect to energy supply and check for leaks.
– Vent the system.
– If necessary adjust the system again.
– Make sure that all safety features on the device and the system work
properly.
For the janitor or other supervisors
Meter reading
It is recommended to read the heat meter at regular intervals, and to
write down the meter readings.
Cooling / Return temperature reading
The cooling, i.e. the temperature difference between district heating
supply and district heating return is of great importance for the total
heat economy. It is therefore very important to observe the supply
and return temperatures. Normal temperature difference is 30-35 °C.
Please note, that the lowest district heating return temperature is directly dependent on the return temperature from the heating circuit
and the cylinder circuit. Therefore, please observe these return temperatures.
Tightening of connections
When reading the heat meter, all fittings and connections should be
checked for leaks. If leaks are detected, contact qualified and authorized personnel immediately.
Please note that the connections may be supplied with EPDM rubber gaskets - in general connection sizes from ¾” to and incl. 1½”
for Kompakt H stations. Therefore take care not to overstrain the
union nuts, as this may result in leaks. The manufacturer accepts
no liability for leaks that result from overstrain of union nuts.
