Safety information
The units were subjected to ex-
tensive 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 safe-
ty 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.
■Only trained specialists may
install and connect the heating
medium, establish electrical con-
nections and carry out mainte-
nance.
■The units must not be installed,
mounted and operated in loca-
tions subject to fire and explosi-
on hazards or exposed to dust-
laden/aggressive atmospheres.
■The units must be installed out-
side traffic zones, e.g. also the
operating areas of cranes.
Planning information
For an optimal room temperature,
several basic rules must be follo-
wed 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.
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.
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 tem-
perature in cooling mode should
be maximum 6 – 8 K below the
ambient temperature.
An excessive temperature dif-
ference (> 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.
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).

5
■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 da-
mage e.g. animals, etc.
Unit description
These units are stationary, indirect-
ly 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 de-
sign, compact, universal and are
easy to install and service.
NOTE
Perfect functioning of the units
is only ensured when the flow
temperature at the unit inlet
and the pump capacity cor-
respond to the selected unit
classification.
The inner supporting unit con-
struction 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 (hori-
zontal or vertical) can be individu-
ally adjusted to suit the local requi-
rements by changing the direction
of rotation of the fan.
The plastic housing can be deta-
ched completely from the sup-
porting 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.
The units are suitable for heating/
cooling rooms with high or low
ceilings and where special impor-
tance 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 hori-
zontally on ceilings or roof struc-
tures.
The units are fitted with an aero-
dynamic, powerful two-speed axial
flow fan with 400V/50Hz external
rotor motor as standard.
Help save on energy consump-
tion in stand-by mode! If the
device, system or component
is not in use, we recommend
disconnecting the power sup-
ply. Components with a safety
function is excluded from our
recommendation!

REMKO PWL
The following information must be
observed for safe unit installation:
■The units must be arranged so
that accessed areas and work-
places are not located in the
direct air stream.
■The units must only be moun-
ted on ceilings or roof struc-
tures 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.
■For mounting on ceilings and
in rooms with low and high
ceilings, the maximum moun-
ting 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 (accesso-
ry) must be fitted.
■The gap between the fan im-
peller and unit housing must be
checked for the same distance.

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 di-
rection 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 horizon-
tally by means of the individually
adjustable air louvres located at
the top of the housing.
This prevents persons being expo-
sed to a direct air stream.

Motor protection is provided via
integrated thermal contacts in
conjunction with a suitable control
unit (accessory).
Connection of the three-phase
motors to the respective control
units takes place via the associated
electrical wiring diagrams.
ATTENTION
Failure to observe the pertinent
requirements, operating inst-
ructions and electrical wiring
diagrams relating to the unit
can give rise to malfunctions
with consequential damage.
This will invalidate the war-
ranty!
Connection of several units
If necessary, several units (also
different sizes) can be operated
parallel via a control unit (accesso-
ry).
The total capacity of the con-
nected units must not exceed the
maximum switching capacity of
the respective control unit.
For thermal motor protection, the
thermal contacts of all motors
must be connected in series. See
separate wiring diagrams.
Only one external control device
(thermostat, day/night control,
etc.) can always be connected per

Commissioning
Draining if there is a risk of
frost
It is not possible to statically drain
the fin heat exchanger completely
in an installed condition.
If necessary, draining is only possi-
ble using compressed air.
Important information about frost
protection
To prevent frost damage, anti-frost
protection must be provided at
temperatures below 0°C.
Where systems in rooms at risk
from frost are not used for ex-
tended periods, under no circum-
stances must “only” water be
present in the heat exchanger.
In such cases, a suitable antifreeze
agent must be added to the hea-
ting medium (water) in a mixing
ratio that is adequate for the place
of use.
The hydraulic capacity loss must
also be taken into account.
■ It should be noted that when
using a speed control (acces-
sory) the power of the control
unit must correspond to the
total power of the connected
motors.
■ It must be ensured that all air
inlets and outlets are open.
ATTENTION
Frost damage to the fin heat
exchanger does not fall under
the warranty!

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)
Decommissioning
Care and maintenance
ATTENTION
It does not suffice to switch off
the unit only via the switch!
During initial commissioning
During initial commissioning, all
regulating, control and safety
devices must be checked for their
proper functioning and correct
adjustment.
■ The power consumption of the
fan must be measured.
The nominal current must not
exceed the values on the rating
plate at the respective opera-
ting speeds.
■ Check the motor protection
function of the fan.
■ Check the complete system for
de-energised installation and
possible vibrations.
■ Check the heating/cooling
medium supply pipes for correct
connection, tightness and insu-
lation.
■ 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 operatio-
nal.
■ 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
■ The surfaces of the units must
be cleaned only dry or with a
moist cloth and a small amount
of soap solution if necessary.
■ Under no circumstances use
high-pressure cleaners or steam
jet equipment to clean the
mounted unit.
■ Do not use caustic cleaning
agents or those containing
solvents.
■ Only suitable cleaning agents
must be used even to remove
heavy fouling.
■ Clean all air inlets and air outlet
louvres.
■ Clean the fan impeller. If ne-
cessary, remove the motor or
protection grille.
■ Clean the heat exchanger fins
either by blowing out, suction
or with a soft brush.
The units generally require no
maintenance. The units and fin
exchanger surfaces must be vi-
sually 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 re-
moving 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 com-
pletely from the unit if required by
loosening the strap adjuster on the
holding straps.
During removal, it must be en-
sured 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.

11
ATTENTION
After carrying out all work on
the units, an electrical safety
test must be carried out in
accordance with VDE 0701.
NOTE
Only authorised specialists
may undertake repairs and
maintenance.
Repair
■ If the fin exchanger surface is
covered with grease or sooty
particles, the exchanger ele-
ment can be removed and
cleaned with a steam-jet degre-
aser using low pressure and a
suitable cleaning agent.
■ Remove heavy fouling on the
fan and aluminium fins with a
soap solution.
■ Clean the condensate tank in
the unit housing to remove dirt
deposits.
To ensure complete drainage of
the condensate tank, the suction
opening of the condensate hose
must be fixed at the lowest point
of the cover.
The condensate sensor must be
arranged slightly above the suction
opening.
Bottom edge of sensor = top edge
of suction opening.
Routing must take place as show
in the following diagram.
