Important notes
Information on the installation manual
This manual enables operating or service personnel
to correctly install the product described below and
to use it safely and efficiently.
It is essential that these individuals read and fully
understand this manual before starting any work.
The basic prerequisite for safe working is to comply
with the safety notes and all instructions in this
manual.
The local regulations for health and safety at work
and general safety regulations also apply.
Qualified staff
Specialist personnel
Specialist personnel are individuals who have suffi-
cient professional or technical training, knowledge
and actual experience to enable them to carry out
their assigned duties, understand any potential haz-
ards related to the work under consideration, and
recognise and avoid any risks involved.
Limitation of liability
The information in this manual has been compiled
with reference to the applicable standards and
guidelines, the state of the art, and our expertise
and experience of many years.
The manufacturer does not accept any liability for
damages resulting from:
Non-compliance with this manual
Incorrect use
Operation or handling by untrained individuals
Unauthorised modifications
The actual scope of delivery may differ from the
information in this manual for special constructions,
additional order options or as a result of recent
technical changes.
Personal protective equipment
Personal protective equipment must be worn for
any work in order to reduce health or safety haz-
ards to the minimum.
The appropriate protective equipment for a job must
be worn for as long as the job takes.
Industrial safety helmet
Industrial safety helmets protect the head from
falling objects, suspended loads, and the effects of
striking the head against stationary objects.
Protective gloves
Protective gloves protect hands from friction, abra-
sions, punctures, deep cuts, and direct contact with
hot surfaces.
Safety shoes
Safety shoes protect the feet against crushing,
falling parts, and slipping on slippery ground.

Transport and storage
Transport
CAUTION!
Danger of injury from sharp edges, sharp cor-
ners and thin sheet metal parts!
Sharp edges, sharp corners and thin sheet metal
parts may cause cuts or grazes.
– Be careful when carrying out any work.
– Wear protective gloves, safety shoes and a
hard hat.
NOTICE!

damage.
Fig. 4: Carrying the unit in pairs
Use only lifting and transport gear designed for the
required load. Always secure the load against tip-
ping and falling.

check the unit for transport damage and complete-
ness.
Storage
Please note:
Store the unit only in its original packaging
Protect the unit from the effects of weather
Protect the unit from humidity, dust and con-
tamination
Storage temperature: –10 to 50 °C
Relative humidity: 95 % max., non-condensing

Safety shoes
Protective gloves
Assemble the device before attaching the plaster-
board bulkhead!
Only work in pairs; preferably use a lift.
DANGER!

Active chilled beams Type DID-E28

Installing the plasterboard bulkhead
The DID-E2 active chilled beams must be clad with
a plasterboard bulkhead provided by others after
attachment to the ceiling. When doing so, the fol-
lowing points must be observed:
The plasterboard bulkhead and material are
provided by others.
The plasterboard bulkhead must be self-sup-
porting; the device may not bear any static
loads of the plasterboard bulkhead.
Install the plasterboard bulkhead so that the air
distribution of the device is not affected.
Hygiene VDI6022
If there is a connection between the secondary
air and the plasterboard bulkhead (e.g. Ä Fig. 8)
the VDI6022 must be observed, e.g. provide a
cleaning option for the plasterboard bulkhead and
for the heat exchanger of the ventilation device.
We therefore recommend direct secondary air
intake through the grille into the ventilation device
Ä Fig. 6.

1 Extension spigot for supply air (optional)
2 Plasterboard bulkhead (provided by others)
3 Suspension (provided by others)
4 Installation subframe for secondary air grille
(optional)
Assembly of the installation subframe (optional)
Create an assembly opening in accordance
with nominal size of the secondary air grille.
Fasten by clamping to the plasterboard bulk-
head (clamping range 9-30 mm)
The installation subframe can be assembled
directly under the device (direct connection to
the device) or at a distance from the device.
The VDI 6022 must be observed here, e.g.
provide cleaning option for plasterboard bulk-
head.
CAUTION!
Risk of injury from a falling secondary air
grille!
If the secondary air grille is not secured, there is
a risk of injury from the grille falling.
Safety cables are provided on the optional instal-
lation subframe for securing the grille. When
adjusting the grille, attach the safety cables to the
grille.
If an installation subframe is not being used, the
grille must be secured on site against falling.

Assembly of extension spigot for supply air
(optional)
Create an assembly opening in accordance
with the nominal size of the supply air grille.
Disassemble the spigot on the device (loosen
screws) and insert it from outside through the
plasterboard bulkhead into the device, then re-
attach it to the device.

Connecting the water pipes
CAUTION!
Hot surface!
Danger of burn or scald injuries when working on
the hot water system.
Before working on the unit, shut down the
system, depressurise it and let it cool down.
The heat exchanger is fitted with water flow and
water return connections:
Fig. 9: Example DID-E2 with 4-pipe-system, water
connections on the right
2-pipe system: 2 water connections
4-pipe system: 4 water connections
Flow and return can be freely selected
Make sure that the water temperature does not fall
below the dew point.

Safety shoes
Protective gloves
Ensure that the surfaces are clean
1. Insert seal and tighten screw connection by
hand.
NOTICE!
Incorrect assembly will damage the heat
exchanger!
Always use a suitable tool to counter the tight-
ening force in order to prevent any damage.
2. Tighten screw connections with a spanner.
NOTICE!
Subzero temperatures will damage the heat
exchanger!
Only fill the heat exchanger if there is no danger
of freezing.
3. Fill the heat exchanger and vent it. To fill the
system, use clean tap water (pH value 6.5 to
9) or a water glycol mixture (max. 30%
glycol).
4. Check the system for leaks immediately
after installation and then in regular inter-
vals.
Connecting the ductwork
DID-E2 active chilled beams are fitted with a pri-
mary air spigot.

For ventilation devices with volume flow controller
(VC), the electrical connection must be made once
assembly is complete. Wiring is done in the terminal
box Ä Fig. 1/2.

Commissioning
Before you start commissioning:
Check active chilled beams for correct position
Remove protective films, if any
Ensure that all connections are correct
Ensure that all active chilled beams are clean
and free from residues and foreign matter
Ensure that the water system including the
heat exchanger has been filled and vented
Commissioning
Carry out the following steps for commissioning:
Switch on the ventilation system.
Switch on the supply voltage (for devices with
volume flow controller).
Check the cooling and/or heating operating
modes (open/close valves).
Set the airflow direction on the grille.
Cleaning
Cleaning the casing
The casing may be cleaned with a damp cloth.
Sticky dirt or contamination may be removed with a
commercial, non-aggressive cleaning agent.
Cleaning agents that contain chlorine must not be
used.
Cleaning the heat exchanger
Personnel:
Specialist personnel
Protective equipment:
Industrial safety helmet
Safety shoes
Protective gloves
CAUTION!
Hot surface!
Danger of burn or scald injuries when working on
the hot water system.
Before working on the unit, shut down the
system, depressurise it and let it cool down.
CAUTION!
Danger of cutting your fingers on the fins of
the heat exchanger
The heat exchanger has thin fins, which are very
sharp; when you touch them, there is a danger of
your cutting your fingers.
To avoid injuries, proceed carefully and wear pro-
tective gloves when you work on the heat
exchanger.
1. To clean the heat exchanger, depending on
the installation situation, disassemble the
secondary air grille or open the cleaning
opening.
2. Carefully clean the heat exchanger with an
industrial vacuum cleaner. Be careful to not
damage the fins. We recommend using a
soft brush with the suction inlet.
3. After cleaning, screw-fix the grille and close
the cleaning opening.

CAUTION!
Risk of injury from a falling secondary
air grille!
If the secondary air grille is not secured,
there is a risk of injury from the grille
falling.
Safety cables are provided on the optional
installation subframe for securing the
