Description of Device
The room air-conditioners in the REMKO RKV 10 W, 13 W, 18 W and RKV 24 W series are split-design, wall­mounted, direct-condensing units.
The way the air conditioning system works is quite sim­ple; warm air is removed from the room to be cooled. The environmentally-friendly refrigerant R 407C trans­ports this warmth just as it does for all other REMKO air-conditioning products.
The units primary function is to air-condition rooms. They also filter and dehumidify the air, thus creating a comfortable climate in the room. The units also have a pure ventilation and dehumidification mode.
All units operate fully-automatically and offer a range of other options thanks to their microprocessor control. They are operated using the supplied infrared remote control.

COOLING
The HEAT mode is not active for these units.
The COOL / DRY mode dehumidifies the room in an unregulated fashion. The tem­perature of the plate fin exchanger of the indoor unit almost always falls below the dew point of the air which causes the moisture in the air to condense on the plate fins. The dehumidification capacity is based on the moisture in the air and the room tem­perature. After the DRY button has been pressed, the desired temperature can be se­lected and the unit begins working. The fan switches off at specific intervals to lower the plate fin temperature. You can exit this mode by switching to a different one.

Shutting Down the Unit
Temporary shutdown
1. Switch the indoor unit off using the remote control.
2. Disconnect the system with the main switch or fuse protection from the power supply.
3. Check the indoor unit for visible damage.
4. Clean the indoor unit as described in the “Maintenance and Service” section.
Never operate the indoor unit without the air filter.
The air filter prevents the plate fin exchanger of the indoor unit from becoming dirty and the perform­ance of the unit from being adversely affected.
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!
Cleaning the filters
Clean both air intake filters on the right and left at inter­vals of no longer than two weeks. If the air is extremely dirty, shorten this timeframe accordingly.
Proceed as follows for cleaning:
1. Open the front of the unit by pushing the grille up and locking it into place.
2. Lift the filters up and then pull them out.
Permanent shutdown
For environmental safety reasons, the air conditioners may only be disassembled by authorised service cen­tres.

Assembly Instructions for Service Personnel
Important instructions prior to installation
à Only use the swivel nuts supplied for the refrigerant
lines. Other components can damage the thread.
à Ensure that the contents of the package are com-
plete and that the units have no visible damage re­sulting from transport. Any problems must be com­municated directly to your contract partner and the shipping company.
Subsequent complaints will not be acknowledged.
à Place the unit in its original packaging as close as
possible to the location where it will be assembled.
à Do not install the unit in the direct vicinity of objects
that emit intense heat. Lights, etc.
à Select a location to set up the unit where air can flow
freely in and out of the device.
Minimum distances are 120 mm on the top and bot­tom.
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 Remove the protective caps of the unit connections
just before connecting the refrigerant lines.
à All electrical connections must meet the relevant re-
quirements. The power supply is only connected to the outdoor part.
à The control line to the indoor unit should be placed
together with the refrigerant line.
à Make sure that the electrical lines have been prop-
erly attached in the electrical terminals.
à Protect open refrigerant lines from moisture with
suitable 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. Install oil elevation arcs.
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 part. 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 from the inside to the 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 The indoor unit and outdoor part of the REMKO air-
conditioner have been 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 refrigerant lines 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.

Units RKV 10 W, RKV 13 W and RKV 18 W can be connected using all five options while the RKV 24 W units can only be connected using options 1 to 3.
Assembling the indoor unit
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. Remove the preinstalled swivel nuts of the units.
5. Keep in mind that the indoor units have been filled with dry nitrogen as a sealant at the factory.
The pressurised nitrogen is released when the swivel nuts are loosened.
Only use the swivel nuts supplied for further as­sembly
.
12
Page 13
6. Use only the tools below for assembly. 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. If, due to structural design conditions, it is not possi­ble to guide the condensation line through as well, make sure that the condensation can drain freely at all times.
7. Before you flare the refrigerant lines, ensure that there is a swivel nut on the hose.
8. Work with the refrigerant lines as shown in the figure below.
Refrigerant line
Flare tool
17. 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.
18. Lay the refrigerant lines from the indoor unit to the outdoor part.
19. Make sure that the refrigerant lines are adequately secured.
Deburrer
20. Take steps, if necessary, to ensure oil recirculation as described in the section on oil recirculation.
21. Place the control line in the same line guideway.
22. Remove the protective caps supplied and the swivel nut caps of the shut-off valves and use these for continued assembly.
Only tools approved for use in cold conditions may be used.
9. Make sure that the flare has the correct shape.
23. Connect the refrigerant lines to the outdoor part as described above.
If the length of the connection line is longer than 5 m, refrigerant must be added to the system during initial operation.
See the section Adding Refrigerant.

Impermeability Check
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 with an absolute final partial pressure of at least 0.01 mbar is put into operation to create a vacuum in the lines. This also removes any moisture from the lines.
A vacuum with a minimum of 0.05 mbar must be 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“.
Adding Refrigerant
The refrigerant required for operating the system is lo­cated in the outdoor part.
For refrigerant lines longer than 5 m per cycle, refriger­ant must be added in line with the information in the op­erating instructions for the respective outer part. Pro­ceed as follows to add additional refrigerant:
Electrical Connection
A 4-wire control line must be led from the indoor unit to the outdoor part. All electrical installations may only be performed by authorised personnel in line 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 performing any work on the unit, it must be unplugged from the power supply and secured against being inadvertently switched on!
Please observe the following:
à We recommend that the customer install a main or
repair switch close to the outdoor part.
à Power is supplied to the indoor units via a connec-
tion line from the outdoor part.
à Fuse protection for the system must occur in accor-
dance with the technical data.
à The electrical terminals of the connections are lo-
cated on the lower right hand side of the indoor unit.

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.
Follow the operating instructions for the pump as well as the instructions below:
à Protect the housing from coming into direct contact
with the condensation.
à Never open the housing of the pump.
à Check the operating current of the pump and the
power supply for consistency.
à Use the alarm contact to switch off the outdoor part.
à Keep in mind that you should only use the alarm
contact together with a contactor or relay to switch off the outdoor part, depending on the load.
à Connect the pump securely to the control line.
Condensation Connection
Condensation forms on the plate fin exchanger of the indoor unit during cooling operation because tempera­tures below the dew point are reached.
The indoor unit is equipped with a collection tray and a condensation hose for the condensation that accumu­lates.
Follow the instructions below to lay 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
necessary to have a different guideway for the con­densation hose, the hose can also be guided to the indoor unit through a different drain.
à If the unit is being operated at outside temperatures
below 0°C, the lines must be placed in such a way that they are protected from frost.
à Make sure there is an adequate
incline for drainage. It must be at least 2 %!
2 % incline
à If the supplied condensation
hose is not long enough, it can be attached to standard hoses with a 17 mm inner diameter.
The condensation pump consists of 2 components:
à The reservoir with sensor
à The pump
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 axis.
Possible assembly positions:
Rotation of the axis up to 30° to the right and left.
Pump
The pump is attached to the right side of the unit (seen from the back) using the supplied, self-adhesive strips.
à Always use suitable hose clips.
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 After the hose has been laid, check to make sure
that condensation can drain freely.

The pump is equipped with an alarm contact that switches off the indoor unit and can also control a cus­tomer-installed malfunction/alarm system.
Connections of the condensation pump on the wa­ter side
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 reservoir and pump are connected to one another with the long suction hose and the pluggable sensor line from the reservoir. To ensure that the pump operates as quietly as possible, the suction hose should not be shortened.
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.
The 6 mm (inner diameter) thick hose is placed at a maximum height difference of 6 meters to the drain. The condensation line should be as vertical as possible to guide the condensation.
If the pump is installed outside the unit, a maxi­mum height difference of 3 m between the lower edge of the unit and the pump mounted above may not be exceeded
.
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.
3. 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.
4. Keep in mind that the pump automatically switches off once the water has been pumped out of the res­ervoir.
5. 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.
6. Check the function of the alarm contact by drastically increasing the amount of water.
The alarm contact should switch off the unit.

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 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 the connection lines to make sure that intake
and outlet lines have not been mistakenly switched.
à Check the refrigerant lines and the insulation for
damage.
à Check that the electrical connection between the in-
door unit and the outdoor part has the correct polar­ity.
à Check all fixtures and suspended parts to ensure
that they are in the proper position and at the correct height.
à Check the surface temperature of the suction line
and determine the evaporator overheating.
To measure the temperature, hold the thermometer on the suction line and subtract the boiling point tempera­ture recorded on the manometer from the measured temperature.
Before starting the test runs, follow the instructions be­low:
1. Remove the caps from the valves.
2. To begin initial operation, briefly open the shut-off valves until the manometer displays pressure meas­uring approx. 2 bar.
3. Check the impermeability of all established connec­tions with a leak locator spray or suitable devices.
4. If you did not find any leaks, open the shut-off valves by turning them all the way counter-clockwise with a hexagonal wrench.
5. If you found leaks, the connection must be re­established.
It is absolutely necessary to create a new vacuum and dry the unit!
If the refrigerant line is longer than 5 m, more re­frigerant should be added to the system
.
Initial Operation
Once all components have been connected and checked, the unit can be put into operation. Initial opera­tion must performed using the certificate and must be documented.
Following initial operation, the operator must be trained in its operation and the initial operation log given to him.
Functional check and test run
To ensure that the unit is functioning properly, a func­tional check must be performed to identify any irregulari­ties during unit operation before the unit is handed over to the operator.
This check is dependent on the installed outdoor part. These procedures are documented in the operating in­structions of the outdoor part in use.
Cooling operation test run
Perform a test run for cooling operation as follows:
1. Switch the customer-installed main switch or fuse on.
2. Adjust the target temperature on the indoor unit to a lower value than the existing room temperature us­ing the remote control.
3. Switch the unit to cooling mode with the remote con­trol.
The compressor starts a couple of minutes later due to the delayed start.
4. Check that cold air is being expelled from the indoor unit and warm air from the outdoor part.
5. During the test run, check all regulating, control and safety mechanisms to ensure that they are function­ing and set properly.
6. Check the indoor unit’s control mechanisms using the functions described in the operating instructions.
Timer, temperature settings, fan mode and dehumidi­fying mode as well as all other mode settings.
7. Measure overheating, outside, inside, outlet and evaporation temperatures and enter these values in the initial operation log.
The functional tests are started via the indoor unit.
The following must be checked:
à Check refrigerant lines for leaks.
à Check that the fan and compressor are running
smoothly.
à Conduct a functional test of the indoor unit and all
program processes.
Completing initial operation
1. Remove the manometer and reattach all parts that were removed.
Make sure that there are seals in the closing caps.
2. Complete the certificate for initial operation.
3. Familiarise the operator with the system and give him the filled out certificate for initial operation.
