Planning information
For an optimal room temperature,
several basic rules must be followed for room heating and cooling
planning.
Heating mode
The following data is required for
room heating planning:
■ Room heat demand
QH (kW)
■ Basic room dimensions
(length, width, height)
■ Required air change
■ Required room temperature
■ Required heating medium tem-
perature for flow and return
The air inlet temperature of the
units should not be below 34°C
and not above 42°C.
At an outlet temperature below
34°C, there is a risk of
unpleasant, cool draughts in the
area of workplaces.
Cooling mode
The following data is required for
room cooling planning:
■ Room cooling load
Qk (kW)
■ Basic room dimensions
(length, width, height)
■ Required room temperature and
possible relative humidity
■ Required cooling medium tem-
peratures for flow and return
To avoid unpleasant draughts at
workplaces, the air outlet temperature in cooling mode should
be maximum 6 – 8 K below the
ambient temperature.
An excessive temperature difference (> 8 K) can lead to the
formation of unpleasant “cold air
zones”.
The circulated total air volume of
the units per hour should be about
4 to 5 times the room volume.
Safety information
The units were subjected to extensive material, functional and
quality inspections and tests prior
to delivery.
The units can however constitute
a hazard if used improperly by
untrained persons or not for the
intended purpose.
Always observe the following safety information:
■ The locally applicable building
regulations must be observed.
■ The operator is responsible for
correct installation of the units,
correct electrical installation and
safe operation of the units.
■ The units must be installed
and operated in a manner that
excludes any risk to persons
through radiated heat.
■ The units must only be attached
to constructions or ceilings with
sufficient load bearing capacity.
■ Attachment must take place
using suitable anchors to be
attached to the unit.
If the outlet temperature is abo-
ve 42°C, an increased upcurrent
of hot air will occur in the ceiling
area.
The range of the hot air current is
reduced and the air in the room
is inadequately penetrated by the
hot air current and intermixed.
Undesired “cold air zones“ form
in the room, and in contrast, an
excessive cushion of hot air forms
in the ceiling area.
This causes unnecessary heat
losses.
4
With inadequate air circulation
volume, the required room climate
is achieved very slowly and with
delay.
An excessive air circulation volume
is preferable since the system is
able to respond more dynamically
and effectively.
The air circulation volume can be
increased using external aids (e.g.
ceiling fans).
■ Only trained specialists may
install and connect the heating
medium, establish electrical connections and carry out maintenance.
■ The units must not be installed,
mounted and operated in locations subject to fire and explosion hazards or exposed to dustladen/aggressive atmospheres.
■ The units must be installed out-
side traffic zones, e.g. also the
operating areas of cranes.
Unit description
■ The units must only be operated
in a completely assembled and
mounted condition.
■ The units must only be opera-
ted within the specified capacity
limits and with the approved
operating media.
■ Safeguards, e.g. barriers must
not be removed or rendered
inoperational.
■ The units must only be operated
within the specified capacity
limits and with the approved
operating media.
■ The air intake grilles must
always be kept free of dirt and
loose objects and the air outlet
must not be closed.
■ Never insert foreign objects into
the unit.
■ The units must not be exposed
to a direct jet of water.
■ Do not operate the units in wet
areas with high humidity (e.g.
car wash).
■ All electric cables of the units
must be protected against damage e.g. animals, etc.
NOTE
Perfect functioning of the units
is only ensured when the flow
temperature at the unit inlet
and the pump capacity correspond to the selected unit
classification.
These units are stationary, indirectly recirculated air cooling/heating
units with copper/aluminium fin
heat exchangers for connection to
a pumped cold/ hot water system
up to max. 90°C.
The units are in an exclusive design, compact, universal and are
easy to install and service.
The units are suitable for heating/
cooling rooms with high or low
ceilings and where special importance is attached to exclusivity.
For example in large rooms such
as:
■ Exhibition halls
■ Sales rooms
■ Shopping centres
■ Business premises
■ Warehouses
■ Production halls
■ Foremen’s offices
■ Large entrance areas
The units must be mounted horizontally on ceilings or roof structures.
The units are fitted with an aerodynamic, powerful two-speed axial
flow fan with 400V/50Hz external
rotor motor as standard.
The inner supporting unit construction is made of galvanised
sheet steel.
The heat exchangers have copper
tubes with aluminium fins.
For removal of the produced
condensate in cooling operation,
a ready to connect condensate
pump is provided.
For an optimal air flow, individually
adjustable louvres are provided at
the top of the housing and fully
adjustable louvre segments are
provided at the bottom.
The air discharge direction (horizontal or vertical) can be individually adjusted to suit the local requirements by changing the direction
of rotation of the fan.
The plastic housing can be detached completely from the supporting lower housing part by
removing the securing clip. The
integrated securing strips prevent
the cover from falling.
The plastic housing of the units is
made of self-extinguishing material
(fire class V-0).
The heaters comply with the basic
health and safety requirements of
the pertinent EU regulations and
are easy to operate.

Mounting the unit
The following information must be
observed for safe unit installation:
■ The units must be arranged so
that accessed areas and workplaces are not located in the
direct air stream.
■ The units must only be moun-
ted on ceilings or roof structures with sufficient load
bearing capacity.
■ The units must be mounted
horizontally and free of stress.
■ The heat exchangers must be
connected so that no vibrations
can be transferred from the unit
to the pipe system or vice versa.
■ Suitable connection fittings,
shut-off valves, vent valves, etc.
must be mounted locally.
Ensure that no persons are standing under suspended loads during installation!
For marking the points of attachment, please use the supplied template
in the packaging. It must be ensured that sufficient space is available
between the unit and ceiling for the media connections.
Fixed bracket (standard) Adjustable bracket (option)
The adjustable brackets (option) can be individually aligned for adjustment.
Maximum mounting heights and operating limits
The maximum mounting heights depend on the maximum range and
direction.
Heating mode
■ For mounting on ceilings and
in rooms with low and high
ceilings, the maximum mounting heights of the unit must be
observed.
■ Before connecting the units to
an existing hot water heating
system, the boiler and pump
must be checked for sufficient
capacity.
■ For maintenance and repairs, a
suitable repair switch (accessory) must be fitted.
■ The gap between the fan im-
peller and unit housing must be
checked for the same distance.
The maximum mounting heights and ranges (at 0.2 m/s) apply to an air
outlet temperature of 20K over the room temperature and ideal conditions of the primary air flow.

We reserve the right to make dimensional and design changes in the interest of technical advances.
Mounting examples
The unit are designed for use in
rooms with high and low ceilings.
The direction of the air flow can
be individually adjusted to the suit,
the building conditions or personal
requirements by changing the direction of rotation of the fan (pole
reversal).
In this way, the air flow, when
using the units in rooms with low
ceilings, can be controlled horizontally by means of the individually
adjustable air louvres located at
the top of the housing.
This prevents persons being exposed to a direct air stream.

Where systems in rooms at risk
from frost are not used for extended periods, under no circumstances must “only” water be
present in the heat exchanger.
In such cases, a suitable antifreeze
agent must be added to the heating medium (water) in a mixing
ratio that is adequate for the place
of use.
The hydraulic capacity loss must
also be taken into account.
Before using for the first time
ATTENTION

position.
Precautions for extended periods
of non-use
■
Disconnect the electrical con-
nection in all poles.
■
Shut-off the hydraulic connec-
tion.
■
Where there is a risk of frost,
the entire system must be
drained if no suitable antifreeze
agent has been added to the
heating medium (water).
(See also page 9)
The units generally require no
maintenance. The units and fin
exchanger surfaces must be visually inspected every six months
and before the start of the heating
period.
In dust-laden environments, the
units must be inspected at shorter
intervals.
For this purpose, the cover of the
unit must be detached from the
supporting part of the unit by removing the 3 securing clips at the
corners.
For inspection purposes, the cover
must be held under the supporting
part with the aid of holding straps.
The cover can be removed completely from the unit if required by
loosening the strap adjuster on the
holding straps.
During removal, it must be ensured that the suction hose and
condensate pump sensor are also
disconnected from the supporting
part.
Securing clip
Important precautions to be taken
prior to all maintenance
■
The units must be disconnected
from the supply in all poles and
locked to prevent unauthorised
reconnection.
ATTENTION
It does not suffice to switch off
the unit only via the switch!
■
It must be ensured that no more
condensate is produced as in
this case the condensate pump
is also disconnected from the
supply and no longer operational.
■
Wait for the fan to stop.
■
Shut-off the water circuit and
lock to prevent unauthorised
opening.
■
Allow the fin heat exchanger to
cool down.
Cleaning the units

Legend/Operating limits
Fin heat exchanger
The copper/aluminium fin heat exchangers consist of circular copper pipes with aluminium fins. The connecting pipes
of thick-wall steel tube are lead out of the housing on the slanted sides. The twistproof connections have a 1“ internal thread.
The heat exchanger and type of housing determine the operating limits.
The maximum flow temperature in heating operation must not exceed 90°C.
The minimum flow temperature in cooling operation must not fall below 4°C.
An operating pressure in the heating/cooling circuit of 16 bar must not be exceeded.
In the immediate vicinity of the units, the temperature must not exceed 70°C (accumulated heat).
Fan and motor
The fan is driven by an external-rotor motor which simultaneously forms the fan hub.
With the external-rotor motor, the impeller with its drive motor is an optimal unit for applications in the field of
heating and ventilation.
The axial flow fan is statically and dynamically balanced.
The rotor housing is made of cast aluminium.

Temperature class: F
■
Degree of protection: IP 54
■ Motor protection
■
The star (Y) winding connection is the low speed setting.
■
The delta (D) winding connection is the high speed setting.
Operating range of motors with insulation class „F“
■
Heating medium flow temperature up to max. 90 °C
■
Ambient temperature (suction temperature) up to max. 40 °C
Motor protection
Thermal contacts are embedded in the motor windings.
These thermal contacts (temperature monitors) open when the maximum winding temperature of 135°C is exceeded (fault). Where the units are used in combination, all thermal contacts must be connected in series. This
theoretically allows any number of motors to be protected with a motor protection device.
However, the number of air heaters is generally limited by the switching capacity of the control units.
