3 Design and function
3.1 Unit description
The RVD 355-1055 DC room air conditioners have a REMKO RVD...AT outdoor unit as well as an RVD...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 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 is designed for indoor areas, for suspended ceilings with Euroraster dimensions. The cassette is hidden behind the suspended ceiling, only its cover is visible. It is operated by an infrared remote control. The indoor unit consists of a fin evaporator, evaporator fan, regulation system and condensate tray with condensate pump.
Floor consoles, wall consoles, refrigerant piping and winter fan speed control are available as accessories.
Refrigerant piping is used to connect the indoor unit to the outdoor unit.

4 Operation
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. The indoor unit can also be operated via an optional cabled remote control.
Manual mode
The indoor units can be put into operation manually. Press the MANUAL key on the cover's receiver unit to first activate automatic mode and then test mode. Pressing the button a third time switches the unit off. Pressing the button again switches back to automatic mode.
The following settings apply for manual operation:
Cooling mode: 24 °C, fan speed: AUTO
Test mode: 30 minutes cooling, high fan speed, the IR remote control is deactivated, after 30 minutes the unit changes over to automatic mode
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.
Fig. 5: Maximum distance
! 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.

5 Installation instructions for qualified personnel
5.1 Important notes prior to installation
Transport the unit in its original packaging as close as possible to the installation location. You avoid transport damage 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 on the corners and not on the refrigerant or condensate drainage connections.
The refrigerant piping (injection and suction pipe), valves and connections must be insulated against vapour density. If necessary also insulate the condensate drainage line.
- Select an installation location which allows air to freely flow through the air inlet and outlet (see section "Minimum clearances").
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.
Only open the shut-off valves on the refrigerant piping after installation is complete.
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.
Avoid unnecessary bends. This minimises the pressure loss in the refrigerant piping and ensures that the compressor oil can flow back without obstruction.
Use the fastening materials provided in the scope of supply for the units.
Use four supports and the associated hooks to attach the ceiling cassette.
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
A wall opening of at least 70mm diameter and 10mm incline from the inside to the outside must be created.
To prevent damage to the lines, the interior of the wall opening should be padded or, for example, lined with PVC pipe (see figure).
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 using 4 threaded rods 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.
REMKO RVD series
5.4 Selection of installation location
Indoor unit
The indoor unit is designed for horizontal ceiling installation. The minimum distance from the floor should be 2 metres.
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
The unit should be at least 10 cm off the ground when mounted on the roof or ground. A floor bracket is available as an accessory.
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). This could be a small roof. However, the discharging warm air flow must not be affected by the measures.
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. Additional stabilisation is recommended. This can be realised with wire ropes or other constructions.
Fig. 20: Windbreak
1: Wind
Snow
The unit should be wall-mounted in areas of heavy snowfall. Installation should be at least 20 cm above the expected level of snow to prevent snow from entering the outdoor unit. An optional wall bracket is available as an accessory.
Fig. 21: Minimum clearance to snow
1: Snow
Installation inside buildings
■ Ensure that heat can dissipate adequately when placing the outdoor unit in cellars, lofts, adjoining rooms or halls (Fig. 22).
Install an additional fan with a rated flow comparative to that of the outdoor unit being installed in the room and which can compensate any additional pressure loss in ventilation ducts (Fig. 22).
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 piping connection provided by the customer takes place on one corner of the unit, inside the suspended ceiling. Once installed, the connections should be insulated to make them vapour diffusion proof.
! 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.
! NOTICE!
All work must be carried out in a way that prevents dirt, particles, water etc. from entering, refrigerant lines!
! NOTICE!
A detachable connection may only be established outside the room. To connect the indoor units, use only the supplied, non-detachable union nuts or provide a firm connection.
Connection of the unit panel
The unit panel is bolted onto the ceiling cassette with the 4 screws supplied. Connect the connection cables between the unit panel and ceiling cassette together. When doing so, note that the connection cable of the swing motors must be connected directly to the control board of the ceiling cassette at contact CN14 (swing). A cable with connecting plug may have been plugged in at the factory. This must be removed for installation.
The following instructions describe the installation of the cooling cycle and the assembly of the indoor unit and the outdoor unit:
- The required pipe diameters are given in the table "Technical data".
-
Install the indoor unit and connect the refrigerant piping as described in the operating manual for the indoor unit.
-
Use the wall or floor brackets to fit the outdoor unit against structural parts approved to support the static load (refer to the installation instructions for the brackets).
-
Ensure that structure-borne sound is not transferred to parts of the building. Use vibration dampers to reduce the effects of structure-borne sound!
-
Lay the refrigerant piping from the indoor unit to the outdoor unit. Ensure that the fastenings are adequate and if necessary, take appropriate oil return measures!
-
Remove the factory-fitted protective caps and union nuts on the connections. These should be used later in the installation process.
-
Before flanging the refrigerant piping, ensure that the union nut is fitted on the pipe.
-
Prepare the laid refrigerant piping as shown below (Fig. 31 and Fig. 32).
-
V erify that the shape of the flange is correct (Fig. 33).
-
First connect and hand-tighten the refrigerant piping to ensure it is correctly seated.
-
Then tighten the fittings with 2 appropriately-sized open-ended spanners. Use a spanner to counter the force when tightening the fitting (Fig. 34).
-
Use insulation hoses which are designed for this temperature range and are diffusion proof.
-
Observe the permitted bending radius for the refrigerant piping during installation. Never bend a pipe twice in the same place. Brittleness and cracking can result.
-
Apply appropriate heat insulation to the installed refrigerant piping, including connector.
-
T ake the same action at the shut-off valves for all subsequent refrigerant piping.

6.3 Leak testing
Once all the connections have been established, the pressure gauge station is attached to the corresponding Schrader valve connection as follows:
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!
The time required to generate the vacuum is dependent on the final pressure pipe volume of the indoor units and the length of the refrigerant piping. However, the process will take at least 60 minutes. Once any foreign gases and humidity have been completely extracted from the system, the valves on the pressure gauge station are closed and the valves on the outdoor unit are opened as described in the "Commissioning" section.
6.4 Adding refrigerant
The units contain a basic quantity of refrigerant. In addition, an additional amount of refrigerant must be added for refrigerant piping lengths exceeding 5 metres per circuit. Refer to the following chart:
| Up to and | incl. 5m | From 5m to max. length |
| RVD 355 DC | 0 g/m | 15 g/m |
| RVD 525 DC | ||
| RVD 685 DC | 30 g/m | |
| RVD 1055 DC |
CAUTION!
Wear protective clothing when handling refrigerant.
DANGER!
Only refrigerant in a liquid state may be used to fill the cooling cycle!
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 with a greenhouse 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.
7 Condensate drainage connection and safe drainage
Condensate drainage connection
If the temperature falls below the dew point, condensate will form on the cooling fins during cooling mode. A collection tray together with a condensate pump and liquid level switch are fitted as standard below the cooling fins. If the liquid level switch trips a protective shutdown due to inadequate removal of the condensate, the pump will switch on immediately and run on for approx. three minutes.
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.
If the level of the condensate drainage line on the unit is above that of the outlet, route the pipe vertically upwards and then with an incline to the drain.
Route the unit's condensate drainage line freely into the drain line. If the condensate runs directly into a sewer pipe, fit a trap to prevent any unpleasant odours.
When operating the unit at outside temperatures below 4 °C, ensure the condensate drainage line is laid to protect it against frost. If necessary, fit a pipe heater.
Following installation, check that the condensate run off is unobstructed and ensure that the line is durably leak tight.
Safe drainage in the event of leakages
Local regulations or environmental laws, for example the German Water Resource Act (WHG), can require suitable precautions to protect against uncontrolled drainage in case of leakage to provide for safe disposal of escaping air conditioning fluid or hazardous media.
NOTICE!
The max. pump pressure of the condensate pump is 500/750 mmWS. Capacity reductions can result from external influences such as air-side counter-pressure, soiling or wear. In order to guarantee safe functional operation, we recommend observing a maximum delivery height of 450/700 mm!
REMKO RVD series
! NOTICE!
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.

8 Electrical wiring
8.1 General connection and safety instructions
A protected power supply cable is to be connected to the outdoor unit and a four-core control line with a minimum cross-section of 1.5mm^2 . To avoid EMC interference, only use shielded cable for this purpose and connect the shielding on both sides.
DANGER!
All electrical installation work is to be performed by specialist companies. Disconnect the power supply when connecting the electrical terminals.
NOTICE!
The electrical connection for the units must be made at a separate feedpoint with a residual current device in accordance with local regulations and should be laid out by an electrician.
We recommend using shielded wires for the control lines.
We recommend that a mains/repair switch be installed near the outdoor unit.
The terminal blocks for establishing the connections are located on the side of the unit. When the unit is installed, measurements can be made from the front by removing the cover.
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.
The control lines used should comprise shielded wire, if laid in areas exposed to strong magnetic fields.
Details concerning the electrical protection of the system are provided in the technical data.
8.2 Connecting the indoor unit
Make the connection as follows:
- Open the air inlet grill.
- Loosen the switch cabinet's cover ( Fig. 38).
- Feed the voltage-free cable through the edge protection rings on the control box and clamp the cable in the strain relief.
- Then connect the cable in accordance with the wiring diagram (see chapter "Electrical wiring diagram").
- Connect the electrical plugs on the cover to the mating connectors on the cassette. It is not possible to incorrectly connect these.
- Re-install all disassembled parts.

8.6 Connection of a superordinate controller provided by the customer
Units of type RVD can be switched on and off by a superordinate controller. In order to utilise the potential-free contact for externally switching the unit on and off, it is first necessary to remove the jumper (JR6) at the indoor unit control board. The contacts are then available.
Fig. 49: Removing the jumper
The building controller is now connected via the two outer contacts of the plug labelled ON - OFF. If the connection between the two contacts is open, the system is in stand-by mode. The "Operation LED" and the "Timer LED" blink alternately. The unit can no longer be switched on using the remote control.
Fig. 50: Open contact

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:
- Check all refrigerant piping and valves for leak-tightness using leak detection spray or soapy water.
- Check the refrigerant piping and insulation for damage.
- Check the electrical connection between the indoor unit and the outdoor unit for correct polarity.
- 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.
! NOTICE!
Check that the shut-off valves and valve caps are tight after carrying out any work on the cooling cycle. Use appropriate sealant products as necessary.
Functional checks and test run
Check the following points:
- Leak-tightness of the refrigerant piping.
■ Compressor and fan running smoothly.
In cooling mode, cold air output by the indoor unit, and warm air output by the outdoor unit.
■ Function test of the indoor unit and all program sequences.
Check of the surface temperature of the suction pipe and that the vaporiser is not 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. - Record the measured temperatures in the commissioning report.
Function test of the cooling and heating modes
- Remove the protective caps from the valves.
- Start the commissioning procedure by briefly opening the shut-off valves on the outdoor unit until the pressure gauge indicates a pressure of approx. 2 bar.
- Check all connections for leaks with leak detection spray and suitable leak detectors.
- If no leaks are found, fully open the shut-of f valves by turning them anti-clockwise using a spanner. If leaks are found, remedy the faulty connection. It is imperative that the vacuum creation and drying steps are repeated.
- Activate the main circuit breaker or fuse.
- Use the remote control to switch on the unit and select the cooling mode, maximum fan speed and lowest target temperature.

13 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!
Contact Remko GmbH & Co. KG to sign up for a maintenance contract
Care
- Ensure that the indoor unit and outdoor unit are free of dirt, mould and other deposits.
Only clean the units with a damp cloth. Do not use any caustic, abrasive or solvent-based cleaning products. Do not use a jet of water.
- Clean the fins on the indoor unit and outdoor unit prior to long shutdown periods.
Maintenance
It is recommended that you take out a maintenance contract with an annual service from an appropriate specialist firm.
For systems which operate year-round (e.g. in server rooms), the maintenance intervals must be reduced accordingly.
This enables you to ensure the operational reliability of the plant at all times!

1) see note below
Cleaning the cover on the indoor unit
- Disconnect the power supply to the unit.
- Open and fold down the air inlet guard on the cover. The filter is held in place by the flaps screwed in at the side of the guard (Fig. 56).
- Clean the grill and cover with a soft, damp cloth.
- Switch the power supply back on.
Air filter for indoor unit
We recommend cleaning the air filter at intervals of no more than 2 weeks. Reduce this interval if the air is especially dirty.
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 filter
- Disconnect the power supply to the unit.
- Open and fold down the air inlet guard on the cover. The filter is held in place by the flaps screwed in at the side of the guard (Fig. 56).
- T ilt the filter and lift it out (Fig. 56).
- Clean the filter with a commercially available vacuum cleaner (Fig. 57). To do so, turn the dirty side so it is facing upwards.
- Dirt can also be removed by carefully cleaning with lukewarm water and mild cleaning agents. The dirty side should be face down (Fig. 58).
- If water is used, let the filter dry out properly in the air before fitting it back into the unit.
- Carefully insert the filter . Ensure that it locates correctly.
- Close the cover as described above but in reverse order.
- Switch the power supply back on.
- Switch the unit back on.
Cleaning the condensate pump
The indoor unit includes a built-in condensate pump for pumping the condensate to a drain at a higher level.
The pump is more or less maintenance-free. The condensate drainage lines should be checked for dirt at regular intervals. Clean them as required.
If an external pump is also used, observe the maintenance and care instructions in the separate operating instructions.
