Installation
Unpacking
2.1
Remove the transport packaging and check that the product has not been damaged in transit and that
the consignment agrees with the specifications.
When lifting the unit take care not to apply stress to pipes and heat exchanger as this may weaken
them. Avoid lifting the unit by holding the heat exchanger.
Note
: Risk of injury lifting heavy objects.
Micro RTC:
Make sure that each individual room thermostat and its relay box are kept together. They are pre-
configured at the factory. If they are separated see
Preparation
2.2
Choose a suitable installation area in accordance with official regulations.
The system may generate sounds during operation caused by pumps, regulators systems, flows etc.
This should be taken in consideration during installation of the unit so that possible operational sounds
affect the surroundings as little as possible. This means that the system should be installed on well-
insulated walls, such as outer walls or on concrete walls.
Check the applicable regulations of the primary heating supplier. The available differential pressure
should be for :
o
AquaMicro: at least 50kPa and at most 600 kPa
o
Micro DPC, RTC STC, STC2 and HTC at least 50 kPa and at most 400 kPa
Where the differential pressure is higher, a differential pressure controller should be added to the
installation.
Flush out the heating and hot water systems.
Mount the first fix-jig (option) to the connection points. Tighten with 45 Nm.
Carefully loosen the electrical plug from the insulation and attached it to the correct power cable.
See
Make sure that the cable is fasten in the insulation

Mounting
2.3
Mount the substation on the wall using four screws or bolts suitable for the material of the wall and for
the weight of the unit. The unit may be mounted at any height on the wall, but a distance of 1500
–
1800 mm from floor to keyhole fixing may be taken as a guide. The hole pattern for screws/bolts and
the piping connection measures is shown in
