Description of Device
The room air conditioners REMKO RKS 327 H to 371 H
have a REMKO RKS ... H-AT outdoor part which can be
mounted on the wall or set up on the ground outside as
well as a wall-mounted indoor unit RKS ... H-IT which is
set up inside.
The indoor unit generates cool air in the spring and can
be used for heating in the fall.
In addition, it filters and dehumidifies the air, creating a
comfortable room climate. The unit can also be operated just for circulation or dehumidification.
It operates fully-automatically and, thanks to its microprocessor control, also offers a number of other options.
The indoor unit comes with an infrared remote control
which makes it easy to operate.
The outdoor part expels the heat removed by the indoor
unit from the room to be cooled to the outside air.
The environmentally-friendly refrigerant R 407C transports this warmth just as it does for all other REMKO
air-conditioning products.

be disconnected from the power supply and se-
G
cured against being inadvertently switched on!
Cleaning the filter of the indoor unit
Clean the right and left air filter and the extra fine filter
behind them at intervals no longer than every two
weeks.
Clean these filters more frequently if the air contains a
lot of impurities.
Proceed as follows to clean the filters:
à Keep the units free of dirt and other deposits and
keep the outdoor part free of plants.
à Only clean the units with a damp cloth.
Do not use a direct stream water for cleaning.
à Do not use an abrasive cleaning agent or one that
contains solvent.
à If the units are extremely dirty, only use suitable
cleaning materials.
à Both before and after the operating season, ensure
that the diameter of the condensation lines has not
become more narrow as a result of impurities.
Clean if necessary.
à Check how dirty the exchanger plate fins are.
à Clean the unit at regular intervals, if necessary, more
frequently. Replace the air filter of the indoor unit as
described on this page.
Never operate the indoor unit without an original filter.
Without the filter, the exchanger plate fans of the in-
G
door unit would become dirty and the unit would not
operate as efficiently.
à We recommend concluding a maintenance agree-
ment with a company who specialises in this type of
work.
This will guarantee that the system operates safely
at all times!
1. Disconnect the unit from the power supply and secure it from being accidentally switched on.
2. Open the air intake grille by unlocking the catches to
the right and left of the grille and then lift the grille
upwards until it locks into place.
3. Remove the right and left air filter from the front.
4. Then remove the additional fine filter.
5. Keep in mind that the fine filter only filters part of the
air and is located behind only one of the two air filters.
6. Clean the filters using a standard vacuum cleaner.
Cleaning the outdoor part
Prior to taking the unit out of operation for a longer period of time, clean the outdoor part to ensure that the
unit operates smoothly at the beginning of the cooling
season.
à Prior to taking the unit out of operation for a longer
period of time, clean the exchanger plate fins of the
outdoor part.
Wear tearproof gloves to avoid cutting yourself.
G
à Cover the outdoor part with a plastic sheet to prevent
dirt from entering the unit.
7. Carefully remove any heavy impurities from the filters with lukewarm water.
If the filters are wet, dry before replacing.
8. Reinsert the filters and close the air intake grille.

Assembly Instructions for
Service Personnel
Important instructions prior to installation
à Only use the swivel nuts supplied with the refrigerant
lines. Other components can damage the thread.
à The units are only suitable for limited use in com-
puter rooms because after a power outage there is
no guarantee that the units will restart. It is also possible that they will only start again with specific settings.
à The unit-specific, maximum length of the refrigerant
line is 10 or 15 m respectively with a maximum
height difference of 5 or 8 m.
à Ensure the contents of the package are complete
and that the unit has no visible damage from transport.
à Any problems must be communicated directly to
your contract partner and the shipping company.
Subsequent complaints will not be acknowledged.
à Place the units in their original packaging as close as
possible to the location where they will be set up to
prevent damage from transport.
à Do not install the outdoor part and the indoor unit in
the direct vicinity of objects that emit intense heat.
Reflective glass surfaces, lights, etc.
à The condensation line must be placed at an incline
of at least 2 % .
à If this line is connected to the drainage line, an odour
seal must be installed the upper edge of which may
not extend beyond the lower edge of the indoor unit.
à Prior to installation, the electrical values must be
checked for consistency with the data on the type
plate.
à Remove the protective caps of the unit connections
just before connecting the refrigerant lines.
à All electrical connections must meet the relevant re-
quirements.
à The power supply is only connected to the indoor
unit. The unit-specific connection and sensor lines
leading to the outdoor part should be placed together
with the refrigerant lines.
à The indoor unit and the outdoor part of the REMKO
air-conditioner are adjusted to one another from a
technical standpoint.
The guarantee becomes null and void if third-party
components are used .
à Remember that when installing and maintaining air
conditioners, high-pressure and electrical current
can pose hazards.
à During unit operation, some components in the cold
cycle can reach temperatures of more than 70 °C.
Be especially careful when covers are removed.
à The air intake and outlet openings may not be
blocked by furniture, curtains, etc.
à The refrigerant lines may not be bent or pressed.
à Protect open refrigerant lines from moisture with
caps or tape.
à Prevent unnecessary bends to minimise the pres-
sure loss in the refrigerant lines and ensure that the
compressor oil can recirculate properly.
à If the outdoor part is mounted above the indoor unit,
make sure to take steps to recirculate the oil (oil elevation arcs).
à Select a location to set up the unit where air can flow
freely in and out of the device. Minimum distances
can be found in chart below
à Make sure that the electrical lines have been prop-
erly attached in the electrical terminals.
à Make sure that all refrigerant lines including all con-
nectors and valves are insulated against heat and
sealed against diffusion.
Wall lead-throughs
Wall lead-throughs are necessary to establish the connection between the indoor unit and the outdoor unit.
Please observe the following:
à For the connection line to the outdoor part, a lead-
through of at least 70 mm in diameter must be created.
à The lead-through must be placed at an incline of at
least 10 mm between the inside and outside.
à Before beginning work, make sure that there are no
supply lines (water, etc.) located in the vicinity of the
wall lead-through.
à We recommend cushioning the inside of the hole or
lining it with a PVC pipe to prevent the lines from being damaged.
à After assembly is complete, the wall lead-through
must be sealed with a suitable sealing compound.
Do not use any materials containing cement or lime!

Wind
These safety zones ensure that air can flow freely in
and out of the unit, that maintenance and repair work
can be performed and to protect the unit from damage.
If this is not possible, you should provide protection from
the wind. Make sure that the wind protection does not
adversely affect the flow of the air to the unit.
Setup locations for the outdoor part
The unit must be set up on a surface that is level,
smooth and solid. The unit must also be secured
against tipping over.
The outdoor part can either be set up outside or inside a
building. If it is set up outside, follow these instructions
to protect the unit from weather conditions.
Snow:
If the unit is also operated in winter, the outdoor part
should be mounted on the wall.
The unit should be installed at least 20 cm above the
expected snow level to prevent snow from entering the
outdoor part.
A base console can be purchased as an accessory.
Rain:
If the unit is set up on the ground or a roof, there must
be at least 10 cm (measurement X in the illustration below) between it and the surface.
A base console can be purchased as an accessory.
Sun:
The plate fin exchanger (condenser) on the outdoor part
is a heat-emitting component. Direct sunlight also increases the temperature of the plate fins and reduces
the amount of heat expelled by the plate fins exchanger.
If possible, the outdoor part should be installed on the
north side of the respective building.
A small structure should be set up to provide shade for
the unit and protect it from the sun if necessary. However, it must not be allowed to interfere with the flow of
hot air being released from the unit.
Setup inside buildings:
If the outdoor part is set up inside a building, observe
the following.
à Make sure that air can be freely supplied from the
outside, if possible through air openings opposite the
unit that are sufficiently large.
à Ensure that there is adequate soundproofing to pre-
vent excessive noise in residences.
à Never block or shut the intake grille.
à Observe the static and other structural engineering
regulations and requirements for the building.
à Do not set up the unit in areas with lots of dust or ag-
gressive air.
16
à If the outdoor part is set up in a basement, an attic,
in adjoining rooms or halls, make sure that the warm
air can be adequately released.
à Prior to assembly, look at the possible drainage op-
tions (1 to 4) for refrigerant lines, condensation
hoses and control lines.

Oil recirculation
If the outdoor part is set up at a higher level than the indoor unit, appropriate steps must be taken for oil recirculation.
This is usually accomplished by creating an oil elevation
arc that is installed every 2.5 meters of line going up.

Assembling the indoor unit
Prior to assembling the indoor unit, observe the following:
à When assembling the indoor unit, make sure that the
required minimum distances are observed.
à Assemble the indoor unit in such a way that conden-
sation drainage is not blocked and air can always
flow freely in and out of the unit.
à The unit is attached by means of a wall mount.
à The wall mount is attached with screws and dowels
suitable for the wall.
The dimensions of the individual unit types relevant
for attaching them can be found in the section
“Dimensions”.
3. Proceed the same way to remove the right housing
panel from the guiding slots.

4. Loosen the screws and detach the wall mount from
the unit.
8. Work with the refrigerant lines as shown in the figure below:
5. Attach the wall mount and hang the unit in the
mount.
6. Secure unit with the screws into the wall mount.
7. After the unit has been mounted, the disassembled
housing panels must be reattached in the reverse order.
Installation
Installation is performed as follows:
1. The required line cross-sections are provided in the
"Technical Data” table.
Only use refrigerant lines with refrigerator quality.
2. Decide on a drainage option for the indoor unit and
cut the refrigerant connection line hose accordingly.
3. When assembling the unit, observe the bending radii
of the refrigerant lines and never bend the hose in
the same place twice.
This may cause the line to become brittle or crack.
4. Use the following tools for assembly:

5. Remove the preinstalled swivel nuts of the units.
6. Use only the preinstalled swivel nuts for further assembly.
7. Before you flare the refrigerant lines, ensure that
there is a swivel nut on the hose.
18
13. Insulate the installed refrigerant lines including the
connector against heat.
14. Only use insulation hoses sealed against diffusion
that are suitable for this temperature range.
15. If you have selected Option 2 or 4 (drainage through
the wall), guide the condensation water and control
line through the wall lead-through to the indoor unit.
If you also need a condensation pump, it must be installed beforehand.
16. Hang the indoor unit leaning slightly to the back in
the previously assembled wall mount and press the
bottom of the unit into the mount.
17. Place the refrigerant lines between the indoor unit
and the outdoor part.
Make sure that they are adequately secured and if
necessary, take steps to ensure oil recirculation !
18. Place the control line in the same line guideway.
19. Install the outdoor part with the wall or base console
onto stationary building parts approved for this purpose.
Observe the installation instructions for the consoles.
20. Make sure that no structure-borne sound is transmitted to building parts.
Structure-borne sound can be reduced through vibration absorbers!
21. Remove the protective caps supplied and the screw
caps of the shut-off valves and use these for continued assembly.
22. Before you flare the refrigerant lines, ensure that
there is a swivel nut on the hose.
Only use the preinstalled swivel nuts.
23. Connect the refrigerant lines to the outdoor part as
already described.
If the length of the connection line is longer than 5
m, refrigerant must be added to the system during
initial operation.
G
See the section Adding Refrigerant.
Winter Regulation
Mechanism
To ensure that the system functions properly, the pressure and temperature of the refrigerant must be kept
within the operating ranges in the indoor unit and outdoor
part.
The integrated winter regulation mechanism makes it possible to keep operating ranges constant even when outside
temperatures go as low as –7 °C and to maintain the
cooling and heating operation.
The temperature sensor mounted on the output line of
the condenser records the condensation temperature of
the refrigerant in cooling mode.
Impermeability Test
Once all connections have been made, the manometer
station is connected to the corresponding valve connections as described below:
red = small valve = injection pressure.
blue = large valve = suction pressure.
After the connection has been made, an impermeability
test is conducted using dry nitrogen.
The connections that have been established are
sprayed with a leak locator spray to test for impermeability. Tighten the bolts more firmly or, if necessary,
create a new flare.
After this test has been successfully conducted, any excess pressure is removed from the refrigerant lines and
a vacuum pump is put into operation to create a vacuum in the lines.
We recommend using a two-speed vacuum pump with
an absolute final partial pressure of at least 0.01 mbar
at a pump capacity of a minimum of 1.5 m
A vacuum with a minimum of 0.05 mbar must be
G
created!
How long it takes to create the vacuum is based on the
hose line volume of the indoor unit and the length of the
refrigerant lines. However, this process takes a minimum of 30 minutes.
Once foreign gases and moisture have been completely
removed from the system, the manometer station
valves are closed and the valves of the outdoor part are
opened as described in the section "Initial Operation".

Temperature sensor
Winter regulation mechanism
The regulating mechanism controls the operating current of the condenser fan by adjusting the current to the
required condensation temperature.
The winter regulation mechanism gradually adjusts the
condenser ventilator’s motor speed depending on the
operating pressure of the system and outside temperature.
For this reason, the rotating motion of the ventilator can
be completely discontinued in winter.

Condensation drainage on the indoor unit
Condensation forms during cooling operation on the
plate fin exchanger of the outdoor part because temperatures below the dew point are reached.
The drainage trays of the indoor units are equipped with
a condensation hose. This hose must be placed at an
incline to ensure that the condensation drains.
21
Condensation hose on the indoor unit
Ensure the following before laying the condensation
hose:
à The condensation drainage line is generally placed in
the same guideway as the refrigerant lines.
à If as a result of structural design conditions, it is nec-
essary to have a different guideway for the condensation hose, the hose can also be guided to the indoor unit through a different drain.
à Make sure there is an adequate incline for drainage.
It must be at least 2 %!
2 % incline
Follow the operating instructions for the pump and instructions below:
à Protect the housing from coming into direct contact
with the condensation.
à Check the operating current of the pump and the
power supply for consistency.
à Connect the pump securely to the control line.
à Only use the alarm contact together with a contactor
or relay to switch off the outdoor part.
à Do not open the pump housing.
Reservoir with sensor
The reservoir collects the condensation. A sensor
switches the pump on when a specific water level has
been reached.
The electronic sensor allows the reservoir to be rotated
by up to 30° on its access.
Possible assembly positions:
à If the condensation is being guided to a drainage
line, please install a siphon-like hose guideway which
acts as an odour seal.
à If the unit is being operated at outside temperatures be-
low 0°C, the lines must be placed in such a way that
they are protected from frost.
à If the supplied condensation hose is not long
enough, it can be attached to standard hoses with a
17 mm inner diameter.
à Always use suitable hose clips.
à After the hose has been laid, check to make sure
that condensation can drain freely.
Using an external condensation pump
The condensation pump which can be purchased as an
accessory (Ref. No. 1613167) transfers the condensation which accumulates in the indoor unit to drains that
are placed in inconvenient locations, even if the drain is
located above the unit. The pump can be installed inside the unit.
The condensation pump consists of 2 components:
à The reservoir with sensor

The reservoir is attached to the condensation collection
tray connection of the indoor unit via a customersupplied hose (20 mm Ø). The factory-installed flexible
hose of the condensation tray must be disassembled.
The supplied ventilation hose must be used for the reservoir to function properly.
The end of the ventilation hose must at least be at the
same height as the condensation tray to prevent water
from overflowing. The supplied metal wire clips are
used to secure the hose in a vertical position
Keep the hose from being suspended which will prevent
an air pocket from forming.

Initial operation of the condensation pump
Before putting the pump into operation, the lines that
have been laid must be checked to ensure that they are
functioning properly and leakproof.
1. Switch the power supply of the pump on.
2. Pour distilled water into the condensation tray until
the pump switches on from the reservoir.
Pump operation can be heard when it is being operated for the first time or being put back into operation. After it has run for short period, the noise normalises.
3. Keep in mind that the pump automatically switches
off once the water has been pumped out of the reservoir.
4. If upon initial operation there is a lot of noise from vibrating hoses, insulate these hoses using foam
hoses.
Condensation buildup is prevented when using insulated hoses sealed against diffusion.
5. Check the function of the alarm contact by drastically
increasing the amount of water.
The alarm contact should switch off the unit.
The 6 mm (inner diameter) thick hose is placed at a
maximum height difference of 6 meters to the drain.
If the pump is installed outside the unit, a maximum
height difference of 3 meters between the lower edge of
the unit and the pump mounted above may not be exceeded. The condensation line should be as vertical as
possible to guide the condensation.
The reservoir and pump are connected to one another
with the long suction hose and the plugable sensor line
from the reservoir. To ensure that the pump operates as
quietly as possible, the suction hose should not be
shortened.
Electrical connection of the condensation pump
There is an electrical connection area located under the
hose connections. This area also a cover that can be
taken on and off.
The pump is equipped with an alarm contact that
switches off the indoor unit and can also control a customer-installed malfunction/alarm system.
The electrical connections may only be made by authorised service personnel in accordance with the relevant
regulations.
Local guidelines for operation as well as the requirements established by local energy supply companies
must be observed for setup and initial operation.
Prior to Initial Operation
After the pressure check has been performed, the vacuum pump must be connected to the valve connections
of the outdoor part (see section “Impermeability Check”)
by means of the manometer station and a vacuum created.
Prior to initial operation of the unit and after contact with
the cold cycle, the following checks must be performed
and documented in the initial operation log:
à Check the refrigerant lines, the outdoor part and the
indoor unit to ensure that any remaining moisture
has been completely removed.
à Check all refrigerant lines and shut-off valves for
leaks with a leak locator spray or soapy water when
the unit is not in operation.
à Check that the electrical connection between the in-
door unit and the outer part has been correctly attached.
à Check the electrical control line to ensure that it is
securely attached in the terminals.
Loose lines in the terminals can cause fires.
à Check the refrigerant lines and insulation for dam-
age.
à Check all fixtures and suspended parts to ensure
that they are in the proper position and at the correct
height.
Always use a contactor or relay to switch off the
outdoor part!
