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
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.

3 Design and function
3.1 Characteristics of REMKO
inverter air conditioner with
split design
REMKO inverter technology
The air conditioner's condenser is equipped with a
requirement-dependent speed control system. The
power control on conventional air conditioners provides only two states, either ON (full output) or
OFF (no output). The air conditioner turns on
below a specified temperature and turns of
this temperature is reached. This kind of heat regulation is very inefficient. Heat regulation in the
Remko inverter air conditioner is modulated to the
actual need. The electronics system has an integrated frequency-converter which serves to modify
the condenser speed and the speed of the blower
as required. The condenser works at a higher
f when
speed when under full load than under partial load.
The lower speeds ensure a longer operational lifetime for the components, improved coefficient of
performance and lower noise. Lower speeds also
result in lower energy consumption (electricity) and
longer service life. I.e.: inverter air conditioner will
run practically throughout the cooling season. In
all, the highest efficiency possible.
Thanks to innovative inverter technology
air conditioner will almost always operate by
adapting its cooling capacity to the actual
requirements of the cooling season, and will in
fact turn itself off when heat is removed. The
same applies in the opposite direction with
heating.

REMKO RVT series
3.2 Unit description
VT series room air conditioners have a
The R
REMKO RVT...AT outdoor unit as well as an
RVT...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.

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.
Alarms are indicated by a code (see chapter
T
roubleshooting and customer service).
NOTICE!
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 on the right side of the
unit.
The following settings apply for manual operation:
Pressing once: Automatic mode,
Pressing twice: Cooling mode,
Pressing three times: Unit OFF
Infrared remote control
The infrared remote control sends the programmed
settings a distance of up to 8 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.
wo AAA batteries must be inserted into the
T
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.
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 Installation instructions for qualified personnel
5.1 Important notes prior to installation
ransport the unit in its original packaging as
n T
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 Make special preparations regarding the oil
return if the outdoor unit is located above the
indoor unit (see section "Oil return measures").
n Add refrigerant if the basic length of the refrig-
erant piping exceeds 5 metres. For the quantity
of additional refrigerant, refer to chapter
"Adding refrigerant".
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 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 70mm diameter and
10mm incline from the inside to the outside
must be created.
o prevent damage to the lines, the interior of
n T
the wall opening should be padded or, for
example, lined with PVC pipe (see figure).
n After installation has been completed, use a
suitable sealing compound to close off the wall
opening, taking account of fire protection regulations (responsibility of customer). Do not use
cement or lime containing substances!

5.3 Installation materials
The indoor unit is attached to the wall by a wall
bracket and 4 screws (to be provided by the customer).
The outdoor unit is attached by 4 screws and a
wall bracket to the wall or fixed by a floor bracket to
the ground.
Layout, indoor unit
5.4
The indoor unit is designed for horizontal wall
installation above doors. However, it can also be
used in the upper wall area (min. 2.0 m above the
floor).
The minimum room size must be 4 m2.
This varies according to the total fill quantity of the
system. Observe the valid DIN standards for the
calculation!

outdoor unit
Outdoor unit installation location
n The device may be attached only to a load-
bearing structure or wall. Ensure that the outdoor unit is installed only vertically
lation site should be well ventilated.
n To minimise noise, install floor consoles with
vibration dampers and a considerable distance
from acoustically-reflective walls to minimise
noise.
n The minimum clearances specified on the next
page should be maintained when carrying out
the installation. These minimum distances
serve to ensure unrestricted air intake and
exhaust. Additionally, there must be adequate
space available for installation, maintenance
and repair.
n If the outdoor unit is erected in an area of
strong winds, then the device must be protected against them (Fig. 20). The snow line is
to be observed during installation (Fig. 21).
n The outdoor unit must always be installed on
vibration dampers. Vibration dampers prevent
the transmission of vibrations through the floor
or walls.
n A heated, condensate tray ensures that con-
densation from the pan can drain off. Ensure
that the condensate is prevented from freezing
so that it can drain off (gravel, drainage). The
Water Ecology Act is to be observed.
n The outdoor unit must always be installed out-
doors. Do not install the outdoor unit in
enclosed rooms, including basement and
window shafts.
n During installation, add about 20 cm to the
expected snow depth to guarantee unimpeded
intake and exhaust of outdoor air year round
(Fig. 21).
n The installation site of the outdoor unit should
be agreed together with the operator primarily
so that operating noise is minimised and not in
terms of “short routes”. Thanks to the splitdesign technology there are a great deal of different installation options with almost identical
efficiency available.

under the plaster
If the customer routes the refrigerant piping to the unit underneath the plaster, observe the following note.
The principal connection options can be found in the "Connection variants for the indoor unit" and "W
bracket" chapters.
If the refrigerant piping is routed underneath the plaster, ensure that the customer-fitted refrigerant piping
does not protrude from the wall at a 90° angle. As a result of the required bending radius, the unit would then
be very difficult to connect or would possibly be impossible to fasten to the wall mount.
For this reason, route the customer-fitted refrigerant piping with as flat an angle as possible (<30°) out of the
wall, from the left and into the unit. (see Fig. 24).

6.2 Connecting the refrigerant
piping
The refrigerant piping is connected (responsibility
of the customer) on the back side of the units.
Please note that a flare connection is only permissible outside the enclosed room. If this is not possible on site, the connection of the indoor unit must
be established as a permanent connection (e.g.
soldered).
It may be necessary to fit a reducer or flared
adapter to the indoor unit. These fittings are
included with the indoor unit as an accessory kit.
Once installed, the connections should be insulated to make them vapour dif
NOTICE!
Installation should only be performed by authorised specialists.
NOTICE!
The unit is factory filled with dry nitrogen for
leak testing purposes. The pressurised nitrogen
is released when the union nuts are undone.
NOTICE!
Use only tools which are approved for use in an
HVAC environment. (z. B.: bending pliers, pipe/
tubing cutters, de-burrers and flaring tools). Do
not cut refrigerant pipes with a saw.

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
Once the connection has been made successfully
the leak test is carried out with dry nitrogen.
Leak testing involves spraying a leak detection
spray onto the connections. If bubbles are visible,
the connections have not been made properly. In
that case, tighten the connection or, if necessary,
create a new flange.
After completing a successful leak test, the excess
pressure in the refrigerant piping is removed and a
vacuum pump with an absolute final partial pressure of min. 10 mbar is used to remove all of the
air and empty the pipes. Any moisture present in
the pipes will also be removed.
NOTICE!
A vacuum of at least 20 mbar must be produced!

NOTICE!
Check the overheating to determine the refrigerant fill quantity
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 unit contains refrigerant
potential of 675. That means the escape of 1 kg
of this refrigerant has an effect on global
warming that is 675 times greater than 1 kg
CO2, based on 100 years. Do not conduct any
work on the refrigerant circuit or dismantle the
unit - always enlist the help of qualified experts.

NOTICE!
Condensate drainage connection
If the temperature falls below the dew point, condensation will form on the finned condenser during
heating mode.
If condensate is removed via a duct in accordance with DIN EN 1717, ensure that any microbiological contamination present on the wastewater side (bacteria, fungi, viruses) cannot
enter the unit connected to it.
A condensate tray should be installed on the
underside of the unit to drain any condensate.
n The condensate drainage line should have an
incline of min. 2%. This is the responsibility of
the customer
. If necessary, fit vapour-diffusion-
proof insulation.
n When operating the unit at outside tempera-
tures below 4 °C, ensure the condensate
drainage line is laid to protect it against frost.
The lower part of the housing and condensate
tray is also to be kept frost free in order to
ensure permanent draining of the condensate.
If necessary, fit a pipe heater.
n Following installation, check that the conden-
sate run off is unobstructed and ensure that the
line is durably leak tight.

9 Before commissioning
After leak testing has been successfully completed, connect the vacuum pump via the pressure
gauge station to the valve connections on the outdoor unit (see chapter "Leak testing") and create a
vacuum.
Perform the following checks prior to putting the
unit into operation for the first time and after any
work on the cooling cycle. Record the results in the
commissioning report:
n Check all refrigerant piping and valves for leak-
tightness using leak detection spray or soapy
water
.
n Check the refrigerant piping and insulation for
damage.
n Check the electrical connection between the
indoor unit and the outdoor unit for correct
polarity.
n Check that all fastenings, mountings, etc. are
firm and at the correct level.
10 Commissioning
NOTICE!
Commissioning should only be performed by
specially trained personnel and documented
after the certificate has been issued. Observe
the operating manuals for the indoor unit and
outdoor unit when commissioning the entire
system.
Once all the components have been connected
and tested, the system can be put into operation. A
functional check should be performed to verify its
correct function and identify any unusual operating
behaviour prior to handing it over to the operator

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 a yearly 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.

Cleaning the housing
1.Disconnect the power supply to the unit.
2.Open and fold the air inlet grill on the front
side upwards.
3.Clean the grill and cover with a soft, damp
cloth.
4.Switch the power supply back on.
Cleaning the air filter
Clean the air filter at intervals of no more than 2
weeks. Reduce this interval if the air is especially
dirty
.
Please proceed as follows to clean the filters:
1.Lift the front panel of the indoor unit.
2.First press the clip of the filter up and release
the clasp, lift it and pull it out from the front.
5.Clean this filter using a normal vacuum
cleaner
facing upwards.
. To do so, turn the dirty side so it is
3.Pull out the filter
6.Then clean the large air filter with lukewarm
water and a mild detergent. The dirty side
should be face down.
.
7.Rinse the filter with fresh water and shake off
any excess water.
If water is used, let the filter dry out properly
in the air before fitting it back into the unit.
8.Carefully insert the filter. Ensure that it
locates correctly.
9.Close the front panel of the indoor unit again.
4.If your filter has a small air freshening filter
detach it from the bigger filter.
Cleaning the condensate pump (accessories)
The indoor unit may contain an optional integrated
,
or separate condensate pump, which pumps out
any accumulated condensate into higher positioned drains.
Observe the care and maintenance instructions in
the separate operating manual.

13 Shutdown
Temporary shutdown
1.Let the indoor unit run for 2 to 3 hours in
recirculation mode, or in cooling mode at
maximum temperature, to extract any
residual humidity from the unit.
2.Shut down the system using the remote control.
3.Switch of
unit.
4.Cover the unit as far as possible with plastic
foil in order to protect it from the influences of
weather
