The ML 262-522DC room air
conditioning units have a REMKO
ML...DC AT outdoor component as
well as an ML...DC IT indoor unit.
When in cooling mode, the
outdoor component serves to
release the heat extracted by the
indoor unit from the room being
cooled. When in heating mode,
the heat absorbed by the outdoor
component can be released by
the indoor unit into the room
being heated.In both operating
modes, the performance of the
compressor adjusts itself precisely
to the demand, thereby regulating
the target temperature with minimal
temperature fluctuations. This
"inverter-technology" results in
energy savings over conventional
split systems and also reduces noise
emissions to a particularly low level.
The outdoor component can
be installed outdoors or indoors
providing that certain requirements
are met. The indoor unit is designed
to be mounted high up on indoor
walls. Operation takes place using
an infrared remote control.
The outdoor component consists of
a refrigerant circuit with compressor,
fin condenser, condenser fan,
reverse flow valve and throttle
element. The outdoor component is
controlled via the regulation of the
indoor unit.
The indoor unit consists of a fin
vaporiser, vaporiser fan, regulation
system and condensation pan.
Floor consoles, wall consoles,
refrigerant pipes and condensation
pumps are available as accessories.

Installation instructions for qualified personnel
Important notes prior to
installation
Transport the unit in its original
packaging as close as possible
to the installation location.
You avoid transport damages
by doing so.
Check the contents of the
packaging for completeness
and check the unit for visible
transport damage. Report any
damage immediately to your
contractual partner and the
shipping company.
Lift the unit at the corners
and not by the refrigerant or
condensation connections.
The refrigerant pipes (injection
and suction line), valves and
connections must be insulated
against vapour diffusion.
If necessary, also insulate the
condensation pipe.
Select an installation location
which allows air to freely
flow through the inlet and
outlet. (See section "Minimum
clearances").
Do not install the unit in
the immediate vicinity of
devices with intensive thermal
radiation. Installation near
sources of thermal radiation
reduces the output of the unit.
Only open the shut-off valves
of the refrigerant lines after the
installation is complete.
Seal off open refrigerant lines
with suitable caps or adhesive
strips to avoid infiltration of
moisture and never kink or
compress the refrigerant lines.
Avoid unnecessary bends.
You thereby minimize loss of
pressure in the refrigerant lines
and ensure clear return flow of
the compressor oil.
Take special precautions with
regard to the oil return if the
exterior component is located
above the indoor unit.
See section "Oil return flow
measures".
If the basic length of the
refrigerant line exceeds 5
metres, add refrigerant.
The quantity of additional
refrigerant is provided in the
chapter "Add refrigerant".
Only use the union nuts for the
refrigerant pipes included in the
delivery, and remove them only
shortly before connecting the
refrigerant lines.
Make electrical connections in
accordance with the effective
DIN and VDE standards.
Always fasten electric cables
properly to the electrical
terminals. Otherwise a fire
could result.

Interior unit
The indoor unit is designed for
horizontal wall installation above
doors. However, it can also be
used on the upper wall area can
be used (min. 1.75 m above the
surface of the floor).
Outdoor component
The outdoor component is
designed for horizontal installation
on a base in outdoor areas.
It should be placed on level, flat
and firm surface. The unit should
also be secured against tipping
over. The outdoor component can
be set up outside as well as inside
a building. For external installation,
please observe the following notes
to protect the unit from weather
conditions.
Wall openings
A wall opening of at least
70 mm diameter and 10 mm
slope from the inside to the
outside must be made for each
indoor unit
We recommend that the inside
of the opening is padded or
lined, e.g. using a PVC pipe,
to prevent the lines being
damaged.
After installation, the wall
opening should be closed off
with a suitable sealant. Do not
use materials containing cement
or lime!
Installation material
The indoor unit is fastened using
a wall bracket and 4 threaded screws
(provided by the customer).
The outdoor component is
attached to the wall with 4 screws
and a wall bracket or on a pedestal
secured to the ground.

the roof or ground. A pedestal is
available as an accessory.
Sun
The condenser on the outdoor
component gives off heat.
Exposure to direct sunlight further
increases the temperature of the
fins and reduces the heat released
by the finned heat exchanger.
The outdoor component should
be installed on to the north
side of the building whenever
possible. If necessary, take
measures to provide sufficient
shade (responsibility of customer).
This can be accomplished with a
small roof. However, the measures
taken should not affect the flow of
warm outlet air.
Wind
If the unit is being installed in
windy areas, ensure that the
warm outlet air discharges in the
main wind direction. If this is not
the case it may be necessary to
install a windbreak (provided by
the customer). Ensure that the
windbreak does not adversely
affect the air supply to the unit.
Snow
The unit should be wall-mounted
in areas of heavy snowfall.
Installation should then be at least
20 cm above the expected level
of snow to prevent snow from
entering the outdoor component.
An optional wall bracket is
available as an accessory.

adequately when placing the
outdoor component in cellars,
attics, adjoining rooms or halls
(figure 4).
Install an additional fan with
a rated flow comparative to
that of the outdoor component
being installed in the room.
This is used in conjunction with
ventilation ducts to compensate
any pressure losses (figure 4)
Ensure a continuous and
unobstructed air flow from
outside, preferably using
sufficiently large air intakes
placed opposite each
other(figure 4).

The units are factory filled with
dry nitrogen to monitor for
leaks. The pressurised nitrogen
is released when the union nuts
are loosened.
ATTENTION
Unit installation
The indoor unit is attached by
means of a wall bracket, under
consideration of air discharge side
located in the lower part.
1. Mark the mounting points on
the structurally permissible
building sections according to
the dimensions of the unit.
2. Remove the housing's break
out opening if necessary.
3. Connect the refrigerant
lines, electrical cables and
condensation line to the indoor
unit as described below.
4. Hang the indoor unit onto the
wall bracket by tilting it back
slightly and then by pressing
the bottom part of the unit
against the bracket (figure 5).
5. Check that the unit is level.
Wall bracket
for indoor unit
The wall bracket for the unit must
be attached with suitable screws
and anchors.
Installation
Installation may only be
performed by authorised
specialists.
NOTE
Oil return measures
If the outdoor component is
installed at a higher level than
the indoor unit, suitable oil return
measures must be taken. This is
normally accomplished by creating
a bend in the oil line, installed at
every 2.5 metres of rise.
5
Connecting
Connecting the refrigerant
lines
The on-site connection of the
refrigerant lines is carried out at
the rear of the unit.
It may be necessary to fit
a reducing or extending adapter to
the indoor units. These fittings are
included with the indoor unit as an
accessory kit. Once installed, the
connections should be sealed to
prevent vapour diffusion.
The following instructions describe
the installation of the refrigerant
circuit and the assembly of the
indoor unit and the outdoor
component.
1.
The required pipe diameters are
given in the table "Technical
data".
2. Remove the factory-fitted
protective caps and union nuts
on the connections and use
these during installation.
3. Before flanging the refrigerant
lines, ensure that the union nut
is on the pipe.
4. Prepare the refrigerant lines as
shown below
(Page 19, figures 6+7).

6. First connect and hand-tighten
the refrigerant connections
to ensure they are correctly
seated.
7. Now fully tighten the fittings
using 2 suitably sized open-
ended spanners. Use one
spanner to counter the force
when tightening the fitting
(figure 9).
8. Use only diffusion-tight
insulation hoses designed for
this temperature range.
9. Lay the refrigerant lines from
the indoor unit to the outdoor
component. Ensure that they
are adequately fastened and
take measures for the oil return,
if necessary!
10.
During installation, observe
guidelines on the permitted
bending radius for the
refrigerant lines and never bend
a line twice in the same place.
Brittleness and cracking can
result.
12.
Ensure that structure-borne
sound is not transferred to
the building. Use vibration
dampers to reduce the effects
of structure-borne sound!
13.
Prepare the refrigerant lines
for the outdoor component as
described above.
11.
Use the wall or floor brackets to
fasten the outdoor component
where structurally allowed
(refer to the installation
instructions for the brackets).

Slope of the condensation line
at least
2% slope
The condensation hose is designed
to be installed on the left side
(viewed from the front).
All electrical installation
work is to be performed
by specialty companies.
Disconnect the voltage supply
when connecting the electrical
terminals.
ATTENTION
Monitoring for leaks
Once all the connections have
been established, the pressure
gauge station is attached as
follows to the Schrader valve (if
fitted):
red = small valve
= injection pressure
blue = large valve
= suction pressure
Once connected, perform a leak
test using dry nitrogen.
The tightness test involves
spraying a leak detection spray
onto the connections. If bubbles
are visible, the connections have
not been properly made. Tighten
the connection or prepare a new
flange.
If the leak test is successful,
depressurise the refrigerant lines
and start a vacuum pump with an
absolute final partial pressure of
min. 10 mbar to create a vacuum
in the lines. Any moisture present
in the pipes will also be removed.
A vacuum of min. 20 mbar
must be created!
ATTENTION
The time required to generate
the vacuum is dependent on the
pipework volume
of the indoor unit and the length
of the refrigerant lines. The
process will always take at least
60 minutes.
Once any foreign gases and
moisture have been completely
extracted from the system, the
valves on the pressure gauge
station will be closed and the
valves on the outdoor component
will be opened as described in the
chapter on "Commissioning".
Condensate connection
Due to undercutting of the
dew point at the vaporiser,
condensation forms during
coolingand in the condenser
duringheating.
Below the vaporiser is a collection
tray, which must be connected to
a drain.
The lower section of the outdoor
component's housing is designed
to serve as a collection tray. The
condensate connection included
in the scope of delivery is to be
attached here.
The condensation line is to
be installed with a minimum
slope of 2 %. (figure 10).
If necessary, fit vapour diffusion
tight insulation.
Lead the condensation line
freely to the run-off line. If
the condensation runs directly
into a sewer pipe, fit a trap to
prevent any unpleasant odours.
When operating the unit at
outdoor temperatures below
+4 °C, make sure to route
the condensation to prevent
freezing. The lower part of the
housing is also to be kept frost
free by the user, in order to
ensure permanent draining of
the condensate.
If necessary, fit supplementary
pipe heating.
After completed installation,
check for unobstructed
condensation run off and
ensure that a permanent seal is
provided.
Electrical connection
A mains cable must be installed as
voltage supply to the Indoor unit
and a control cable to the outdoor
unit, with appropriate safeguards.
We recommend that a mains/
repair switch be installed near
the outdoor component.
If an optionally available
condensation pump is used
on the unit, then an additional
relay for the shut-off contact
of the pump will be needed to
increase the switching power to
shut off the compressor.
Control cables should be
screened if laid in areas exposed
to strong magnetic fields.
Electrical protection
is provided in accordance with
the technical data.

temperature of the suction pipe
and determination of vaporiser
overheating. To measure
the temperature, hold the
thermometer to the suction
pipe and subtract the boiling
point temperature reading on
the pressure gauge from the
measured temperature.
Documentation of the
measured temperatures in the
commissioning report.
Check that the stop valves
and valve caps are tight after
carrying out any work on
the refrigerant circuit. Use
appropriate sealant products
as necessary.
NOTE
Functional test for the cooling
