1.7 Safety notes for installation, maintenance and inspection
n The refrigerant R32 used in the system is flam-
mable. If applicable, observe the local safety
conditions.
n Keep the cooling circuit clear of other gases
and foreign substances. Only fill the cooling circuit with the refrigerant R32.
n Only use the accessories, components and
appropriately marked parts provided. The use
of non-standardised components may result in
water leaks, electric shocks and fire.
n Only install and store the units in rooms larger
than 4 m2. With a failure to comply, leaks may
result in the room filling with a flammable mixture!
The minimum room size of 4 m2 required for
installation and storage pertains to the basic fill
quantity of the unit. This varies according to the
installation type and total fill quantity of the
system. The calculation must take place in
accordance with valid DIN standards. Make
sure that the installation site is suitable for safe
unit operation.
n Only mount the unit components on structurally
suitable brickwork.
n The units must not be installed in rooms in
which further devices that produce heat are
operated (heaters, open hearths).
n Make sure the installation room is sufficiently
ventilated.
n Interventions in the cooling circuit are only pos-
sible after completely draining the refrigerant.
Never solder or grind unit components!
n Note that refrigerant may be odourless.
n Never operate the air conditioning unit in a
humid room, such as a bathroom or laundry
room. If the humidity is too high, this can cause
short circuits on electrical parts.
n The product must be correctly earthed at all
times, otherwise it may induce electric shocks.
n Attach the condensate drain as described in
the operating manual. The inadequate
drainage of condensate can lead to water
damage in your apartment.
n All persons who intervene in the cooling circuit
must hold a valid certificate from the chamber
of industry and commerce, which confirms their
ability to work with refrigerant.

REMKO BL series
3 Design and function
Unit description
The BL 264-354 DC room air conditioners have a
REMKO BL...AT outdoor unit as well as a BL...IT
indoor unit.
In cooling mode, the outdoor unit serves to output
the heat extracted by the indoor unit from the room
being cooled. In heating mode, the heat taken up
by the outdoor unit can be discharged by the
indoor unit into the room to be heated. In both
operating modes, the output produced by the compressor precisely matches requirements, and
thereby regulates the nominal temperature with
minimal temperature deviations. This "inverter
technology" results in energy savings over conventional split systems and also reduces noise emissions to a particularly low level. The outdoor unit
can be installed in an outdoor area or, providing
that certain requirements are met, an indoor area.
The indoor unit is designed to be mounted high up
on the wall, in indoor areas. It is operated by an
infrared remote control.
The outdoor unit consists of a cooling cycle with
compressor, fin condenser, condenser fan,
reversing valve and throttle element. The outdoor
unit is controlled by the regulation of the indoor
unit.
The indoor unit consists of a fin evaporator, evaporator fan, controller and condensate tray.
Floor brackets, wall brackets, refrigerant piping and
condensate pumps are available as accessories.

max. 6 m
4.1 General notes
The indoor unit is easily operated using the
standard infrared remote control. The indoor unit
beeps to acknowledge the correct transmission of
data. If it is not possible to program the indoor unit
with the remote control, then it can also be manually operated.
Manual mode
The indoor unit can also be switched on manually
if the infrared remote control is lost/defective.
Manual operation is intended for emergency operation and is not suitable for basic unit operation.
Please replace the remote control. The key for
manual activation is located below the housing
cover on the right side.
The following settings apply for manual operation:
Pressing once: Automatic mode,
Pressing twice: Cooling mode,
Pressing three times: Unit OFF
Fig. 6: Maximum distance
Infrared remote control
The infrared remote control sends the programmed
settings a distance of up to 6 m to the receiver of
the indoor unit. Data will only be received correctly
if the remote control is pointed at the receiver and
no objects are obstructing the transmission path.
Two AAA batteries must be inserted into the
remote control in preparation. To do so, remove
the flap from the battery compartment and insert
the batteries the correct way around (see markings). Removing the batteries causes all stored
data to be lost. The remote control will then access
the default settings, which you are free to customise at any time.
Alarms are indicated by a code (see chapter
Troubleshooting and customer service).
NOTICE!
Immediately replace flat batteries with a new
set, otherwise there is a risk of leakage. It is
recommended that the batteries are removed if
the equipment is shut down for longer periods.
Help save on energy consumption in stand-by
mode! If the device, system or component is not
in use, we recommend disconnecting the power
supply. Components with a safety function is
excluded from our recommendation!

5.1 Important notes prior to installation
n Transport the unit in its original packaging as
close as possible to the installation location.
You avoid transport damage by doing so.
n Check the contents of the packaging for com-
pleteness and check the unit for visible transport damage. Report any damage immediately
to your contractual partner and the shipping
company.
n Lift the unit on the corners and not on the
refrigerant or condensate drainage connections.
n The refrigerant piping (liquid and suction pipe),
valves and connections must be insulated to
make them vapour diffusion proof. If necessary
also insulate the condensate drainage line.
n Select an installation location which allows air
to freely flow through the air inlet and outlet
(see section "Minimum clearances").
n Do not install the unit in the immediate vicinity
of devices which generate intensive thermal
radiation. Installation in the vicinity of thermal
radiation reduces the unit output.
n Only open the shut-off valves on the refrigerant
piping after installation is complete.
n Seal off open refrigerant piping with suitable
caps or adhesive strips to prevent the infiltration of moisture and never kink or compress
the refrigerant piping.
n Avoid unnecessary bends. This minimises the
pressure loss in the refrigerant piping and
ensures that the compressor oil can flow back
without obstruction.
n Perform all electrical wiring in accordance with
applicable DIN and VDE standards.
n Ensure the electrical cables are properly con-
nected to the terminals, otherwise there is a
risk of fire.
n Only use the fasteners contained in the scope
of delivery with the units.
n Use four supports and the associated hooks to
attach the ceiling cassette (only applies to
ceiling cassettes).
n Use the insulated condensate hose in the
scope of delivery as a junction piece to the
continuing condensate drain. Secure the condensate drain with the supplied clamps.
5.2 Wall openings
n A wall opening of at least 65 mm diameter and
10mm incline from the inside to the outside
must be created.
n To prevent damage to the lines, the interior of
the wall opening should be padded or, for

5.4 Selection of installation location
Indoor unit
The indoor unit is designed for horizontal wall
installation above doors. However, it can also be
used in the upper wall area (min. 1.75m above the
floor).
Outdoor unit
The outdoor unit is designed for horizontal installation on a base in outdoor areas. The installation
site must be level, flat and firm. The unit should
also be secured to prevent it from tipping over. The
outdoor unit can be set up outside as well as inside
a building. For external installation, please observe
the following notes to protect the unit from the
influence of the weather.
Rain
For floor or roof set-up, the unit should be installed
with at least 10cm ground clearance. A floor
bracket is available as an optional accessory.
Wind
If the unit is being installed in windy areas, ensure
that the warm outlet air is discharged in the prevailing wind direction. If this is not the possible, it
may be necessary to install a windbreak (to be provided by the customer). Ensure that the windbreak
does not adversely affect the air intake to the unit.
An additional stabilization is recommended. This
can, for example, be realized with ropes or other
structures.
Fig. 11: Windbreak
1: Wind
Sun
The condenser on the outdoor unit emits heat.
Exposure to sunlight further increases the temperature of the fins and reduces the heat released by
the finned heat exchanger. The outdoor unit should
be installed on to the north side of the building
whenever possible. If necessary, take measures to
provide sufficient shade (responsibility of customer). One possible solution is to build a small
roofed area over the unit. These measures should
not affect the flow of warm outlet air.
Snow
The unit should be wall-mounted in areas of heavy
snowfall. Installation should be at least 20cm
above the expected level of snow to prevent snow
from entering the outdoor unit. An optional wall
bracket is available as an accessory.
Fig. 12: Minimum clearance to snow
1: Snow
Installation inside buildings
n Ensure that heat can dissipate adequately
when placing the outdoor unit in cellars, lofts,
adjoining rooms or halls (Fig. 13).
n Install an additional fan with a rated flow com-
parative to that of the outdoor unit being
installed in the room and which can compensate any additional pressure loss in ventilation
ducts (Fig. 13).
n Comply with any regulations and conditions
affecting the statics of the building. If necessary, fit acoustic installation.

6.2 Connection of refrigerant piping
The refrigerant pipes should be connected by the
customer on the right-hand side of the outdoor
component.
1. Use the wall or floor brackets to fit the out-
door unit against structural parts approved to
support the static load (refer to the installation instructions for the brackets).
2. Ensure that structure-borne sound is not
transferred to parts of the building. Use vibration dampers to reduce the effects of structure-borne sound!
NOTICE!
Installation should only be performed by authorised specialists.
CAUTION!
6.3 Connection of quick-release couplings
The refrigerant pipes should be connected by the
customer on the right-hand side of the outdoor
component. The pre-filled refrigerant piping are
connected to the outdoor unit by means of the
quick-connector system. Once installed, the connections should be insulated to make them vapour
diffusion proof. The following instructions describe
the installation of the refrigerant piping for the
indoor unit on the outdoor unit.
Please note that the following figures are only
schematic representations. The actual appearance of the units may vary from those shown.
1. Remove the pre-installed plastic cover from
the outdoor unit(Fig. 19).
Both units are pre-filled with refrigerant at the
factory. Suitable protective clothing must be
worn during installation.
NOTICE!
Use only tools which are approved for use in an
HVAC environment.
The refrigerant piping on the indoor unit are
extended at the factory so that the quick-release
couplings can be located outside the building if
they are fed through the masonry.
Fig. 19: Remove the plastic cover
2. Remove the green/black protective caps from
the quick-connectors on the outdoor component, as well as the flexible refrigerant pipes
on the indoor unit (Fig. 20 and Fig. 21).

6.4 Leak testing
Once all the connections have been made, the
pressure gauge station is attached to the Schrader
valve as follows (if fitted):
red = small valve = high pressure
blue = large valve = suction pressure
Leak testing involves spraying a leak detection
spray onto the connections. If bubbles are visible,
the connections have not been made properly.
Then tighten the screw connection.
NOTICE!
The escape of refrigerant contributes to climatic
change. In the event of escape, refrigerant with
a low greenhouse potential has a lesser impact
on global warming than those with a high
greenhouse potential. This device contains
refrigerant with a greenhouse potential of 2088.
That means the escape of 1 kg of this refrigerant has an effect on global warming that is
2088 times greater than 1 kg CO2, based on
100 years. Do not conduct any work on the
refrigerant circuit or dismantle the device always enlist the help of qualified experts.

8 Electrical wiring
8.1 General Information
A protected power supply cable is to be connected
to the outdoor unit and a five-core control line to
the indoor unit respectively.
DANGER!
All electrical installation work is to be performed
by specialist companies. Disconnect the power
supply when connecting the electrical terminals.
WARNING!
All electric lines are in accordance VDE regulations to dimension and to lay.
NOTICE!
The electrical connection of the units must be
carried out in accordance with VDE regulations.
We recommend using an FI circuit breaker that
is sensitive to all currents, as increased leakage
currents can occur.
The control line to the outdoor unit contains a data
cable which is used to establish communication
between the indoor unit and the outdoor unit. This
is used for controlling the cooling and heating
capacity and for forwarding alarm codes to the
indoor unit. If the length is insufficient, you can
extend the control lines on the indoor unit.
Make the connection as follows:
1. Open the panel of the unit.
2. Remove the covers on the right-hand side
(Fig. 28).
3. Feed the control line through the opening on
the rear of the unit in the connection area.
4. Connect the control line to the terminals
(Fig. 28).
5. Re-assemble the unit.
We recommend using shielded wires for the
control lines.
Check all plugged and clamped terminals to
verify that they are seated correctly and make
permanent contact. Tighten as required.
8.2 Connecting the indoor unit
n We recommend that a mains/repair switch be
installed near the outdoor unit.
n The terminal blocks for making the connections
are located at the rear of the unit. When the
unit is installed, measurements can be made
from the front by removing the cover.
n If an optional condensate pump is used as an
accessory in conjunction with the unit, it may
be necessary to install an additional relay with
a higher contact rating after the switch-off contact on the pump to switch off the compressor.

12 Care and maintenance
Regular care and observation of some basic points
will ensure trouble-free operation and a long
service life.
DANGER!
Prior to performing any work, ensure the equipment is disconnected from the voltage supply
and secured to prevent accidental switch-on!
Care
n Ensure the unit is protected against dirt, mould
and other deposits.
n Only clean the unit using a damp cloth. Do not
use any caustic, abrasive or solvent-based
cleaning products. Do not use a jet of water.
n Clean the fins on the unit prior to long shut-
down periods.
Maintenance
n It is recommended that you take out a mainte-
nance contract with an annual service from an
appropriate specialist firm.
This enables you to ensure the operational reliability of the plant at all times!
NOTICE!
Statutory regulations require an annual leak test
for the cooling cycle dependant on the refrigerant quantity. Inspection and documentation of
the work performed is to be carried out by specialist technicians.

grill upwards and allowing it to engage
(Fig. 34).
3. Raise the filter and pull it out in a downwards
direction (Fig. 34).
4. Clean the filter with a commercially available
vacuum cleaner (Fig. 35). To do so, turn the
dirty side so it is facing upwards.
5. Dirt can also be removed by carefully
cleaning with lukewarm water and mild
cleaning agents (Fig. 36). The dirty side
should be face down.
6. If water is used, let the filter dry out properly
in the air before fitting it back into the unit.
7. Carefully insert the filter. Ensure that it
locates correctly.
8. Close the front side as described above in
reverse order.
