Safety notes
The units were subjected to
extensive material, functional and
quality inspections prior to delivery.
However, dangers can emanate
from the units if they are used
improperly or not as intended by
untrained personnel.
Always observe the following
safety instructions:
■The respective building code
regulations must be observed as
a basic rule
■The operator is responsible for
the proper unit installation, the
correct electrical installation and
the safe operation of the units
■The units must be set up,
installed and operated in such a
way that no one is endangered
or stressed by radiated heat
■The units may only be fastened
to structures or ceilings made
of construction materials of
sufficient load bearing capacity
■The fastening must take place
with bearing anchors, which are
to be fastened to the unit
■Assembly, connection of the
heating medium, connection
of the electrical system and
the maintenance may only be
carried out by trained, qualified
persons
■The units may not be installed
or operated in potentially
flammable or explosive
environments, or in extremely
dusty / aggressive air
Planning notes
In order to achieve an optimum
comfortable temperature in a
room, the planning of the room
heating or room cooling must
follow some fundamental rules.
Heating mode
The following data is required to
plan the room heating:
■Room heating requirements
QH(kW)
■Basic measurements of the room
(length, width, height)
■Desired air exchange
■Required room temperature
■Required heating medium
temperatures for supply and
return flow
The air outlet temperature of the
units should not fall below 34° C
or exceed 42° C.
If the outlet temperature is below
34 ℃, there is the risk of unpleasant
cool drafts in the work area.
If the outlet temperature is
higher than 42° C, an increased
temperature in the ceiling area
occurs.
The casting distance of the
warm air flow is reduced and
the air in the work area cannot
be sufficiently penetrated by the
warm air flow and mixed.
Undesired "cold air zones" form in
the work area and excessive warm
air pockets form in the ceiling area.
The result is unnecessary heat
losses.
Cooling mode
The following data is required to
plan the room cooling:
■Room cooling load
QH(kW)
■Basic measurements of the room
(length, width, height)
■Required room temperature and
possibly relative humidity
■Required cooling medium
temperatures for supply and
return flow
In order to prevent unpleasant
draughts in the work area, the
air outlet temperature in cooling
mode should be no more than
6 - 8 K below the ambient
temperature.
If the temperature difference is
excessive (> 8 K), unpleasant “cold
air zones“ may form.
The circulated total air quantity of
the units per hour should be 4 to 5
times the room volume so that the
system can react dynamically and
effectively.
If the air circulation is undercut,
the desired room climate control is
very slow-acting and delayed.
In order to prevent the units
dripping, the fan should be set
to the lowest speed and the air
discharge direction should be
selected to be parallel to the
ceiling (horizontal). The medium
temperature may also have to be
adjusted accordingly in order to
reduce condensate dripping.

5
■The units must be installed away
from traffic zones and installed
by crane, for example
■The units may only be operated
in completely assembled
condition
■Safety components (e.g.
protection grids) must not
be removed or rendered
inoperative
■The units may only be used as
intended within the specified
output limits and with the
approved conveying media
■The intake protection grid must
always be free of dirt and loose
objects; the unit outtake may
not be covered or closed
■Never insert foreign objects into
the unit
■The units may not be exposed
to direct jets of water
■Do not operate the units in wet
areas with high humidity (e.g.
automatic car washes, etc.)
■All electrical cables for the
units must be protected against
damage (e.g. by animals etc.)
Unit description
The units are stationary, indirectly
fuelled recirculation cooling/
heating units with Cu/Al finned
heat exchangers for connection
to a pumped cold / hot water
network up to max. 90 °C.
The units have an exclusive
and low design, have universal
applications, and are easy to install
and service.
NOTE
Fault-free function of the units
is only guaranteed if the inlet
temperature at the unit inlet
and the pump performance are
appropriate for the selected
unit classification.
The tube heat exchangers are
made of copper tubes with
aluminium fins on top.
A condensate pump is installed
ready for connection to remove
the condensate that occurs in
cooling mode.
For optimised air guidance,
individually adjustable fins are
installed in the top of the housing
and fins that can be adjusted
completely are installed in the
bottom.
The air discharge direction
(horizontal or vertical) can be
adjusted individually to the on-site
requirements my changing the
fan’s direction of rotation.
The plastic housing can be
removed from the bearing housing
parts by removing the locking bar.
The integrated securing straps
prevent the hood falling down.
The plastic housing on the
units consists of materials that
extinguish themselves in the event
of fire (corresponding to fire class
V-0).
The units conform to the
fundamental health and safety
requirements of the appropriate
EU regulations, and are simple to
operate.
The units are used wherever high
and low-ceilinged rooms have to
be heated or cooled and wherever
great value is placed on exclusivity.
Examples of large rooms include:
■Exhibition halls
■Salesrooms
■Malls
■Business premises
■Warehouses
■Production halls
■Design offices
■Large entrance areas
The units must be installed on
the ceiling or roof structure in
a horizontal position.
The units are equipped with
an aerodynamically designed,
2-speed, high-performance axial
fan with a 400V/50 Hz external
motor.
The inner, load-bearing unit
structure is made of galvanised
steel sheet.
Help by reducing energy
usage in stand-by operation!
If the unit, the system or
the components are not
being used, we recommend
disconnecting the power
supply.
Our recommendation does
not apply to safety relevant
components.

Installation examples
The units are designed for use
in both high and low-ceilinged
rooms.
The fan’s direction of rotation can
be changed (pole switching) in
order to adjust the air direction
individually to the structural or
personal requirements.
Therefore, if the units are used in
low-ceilinged rooms, the air flow
can be controlled horizontally
in the room by the individually
adjustable air discharge fins that
are in the top part of the housing.
This prevents people being
exposed to direct airflow.

Commissioning
Drainage when at risk of
freezing
Complete static drainage of
the finned heat exchangers is
not possible in the condition as
installed.
If necessary, drainage is only
possible with the assistance of
compressed air.
Important information
regarding anti-freeze protection!
In order to prevent frost damage,
a frost protection device must be
used at temperatures below 0 °C.
In systems that are
decommissioned in rooms at risk of
freezing, the heat exchanger may
never contain "only" water.
The heating medium (water) must
then be supplemented with a
suitable antifreeze with a sufficient
mixture ratio for the environment.
In the process, the hydraulic
output loss must be taken into
account.
■ Note that if using a speed
controller (accessory), the
regulating device output must
be attuned to the total output
of the connected motors
■ Check whether all air discharge
and intake openings are opened
accordingly
CAUTION
Commissioning can only take
place once it has been assured
that the proper assembly
and electrical installation
correspond to the applicable
provisions of the EC Directives.
CAUTION
No guarantee claims can be
accepted for frost damage on
the finned heat exchangers!

respective switching speeds
■ Check the motor protection
function of the fan
■ Check the entire system for
tension-free installation and
potential vibrations
■ Check the heating/cooling
medium supply lines for proper
connection, tightness and
insulation
■ Ensure that no more
condensate is formed, as
the condensate pump is also
disconnected from the power
supply in this case and is
therefore not functioning
■ Wait until the fan stops
■ Shut off the water circuit and
safeguard it to prevent it being
opened inadvertently
■ Allow the finned heat
exchanger to cool
Cleaning the units
■ Only dry clean the unit surfaces
or clean with a moistened

■ Clean the heat exchanger fins
by blowing, with suction or
using a smooth brush
The units are basically
maintenance-free. Perform a visual
inspection on the units and finned
heat exchanger surface every six
months and before the heating
period begins.
If the units are subjected to
excessive dust, perform the
inspections at more regular
intervals.
To do this, remove the 3 locking
bars from the corners of the
