REMKO BL Safety notes Carefully read this operating manual before starting the unit for the first time. It contains useful tips and notes as well as hazard warnings to prevent injury or material damage ! . Failure to follow the directions in this manual not only presents a danger to people, the environment and the system itself, but will void any claims for liability. ■ Keep this operating manual and the refrigerant data sheet near to the unit.
Transportation and packaging The units are delivered in strong transport packaging. Immediately check the units on delivery and make a note of any damage or missing parts on the delivery note. Inform the forwarding agent and contractual partner. No warranty can be assumed for later claims. Cooling circuit diagram for the outdoor component Condenser fan Reverse flow valve Compressor Floor consoles, wall consoles and condensation pumps are available as accessories.
REMKO BL Operation The indoor unit is easy to operate using an infrared remote control. This is supplied as standard. The indoor unit beeps to acknowledge the correct transmission of data. If it is not possible to program the indoor unit using the remote control, it can also be operated manually. Manual mode Display on indoor unit The indoor units can be commissioned manually. After the air inlet screen has been opened, the inner recessed key can be pressed and automatic mode can be activated.
Keys on the remote control 2. Cooling mode In this mode, the warm air in the room is cooled down to the desired temperature. "TIMER OFF" key Press this key to program the automatic switch-off time of the unit within the next 24 hours. 3. Dehumidification mode In this mode the room is mainly dehumidified and the adjusted temperature is maintained. "HR" key Press this key to set the hours. 4. Heating mode In this mode, the warm air in the room is warmed to the desired temperature.
REMKO BL Key functions A symbol is shown on the display to indicate that the settings are being transferred. Stand by of remote control The remote control standby mode is signalled by the blinking dot on the remote control. RESET key The remote control can be reset by pressing the RESET key in the battery compartment. The time can then be programmed (see "CLOCK key"). RESET CLOCK Key HR/MIN CLOCK Your air conditioner is activated and deactivated by pressing the ON / OFF key.
▲/▼ Keys The ▼ key can be used to reduce the desired target temperature, the ▲ key can be used to increase it. In automatic mode, the temperature can be increased or decreased by 1°C. In dehumidification mode, no temperature adjustment can be made.
REMKO BL DEHUMIDIFICATION MODE In dehumidification mode, the target temperature is set to 24°C. Due to the low temperature of the refrigerant, the temperature of the air at the condenser falls below the dew point. The excess moisture in the air is condensed by the vaporiser, the room is dehumidified. The fan speed is permanently set to the lowest setting in order to achieve a maximum level of dehumidification. The compressor switches on and off in intervals between 17°C and 24°C.
SLEEP Key A programming function is activated with this key, which increases the target temperature in cooling mode by 1°C after one hour and by 2°C after 2 hours. In heating mode, the target temperature is decreased by 1°C after one hour by 2°C after 2 hours. The unit switches off automatically after 8 hours. SLEEP TIMER Key SLEEP SLEEP The activation and switch-off time can be programmed with this key.

REMKO BL Troubleshooting and customer service The units and components are manufactured using state-of-the-art production methods and tested several times to verify their correct function. However, if malfunctions should occur, please check the functions as detailed in the list below. Please inform your dealer if the unit is still not working correctly after all function checks have been performed! Malfunctions Fault The unit does not start or switches itself off.

REMKO BL 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. This helps to prevent damage during transportation. ■ 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.
Wall openings Selection of installation location Wind ■ A wall opening of at least 70 mm diameter and 10 mm incline from the inside to the outside must be made for each indoor unit. Indoor unit If the unit is being installed in windy areas, ensure that the warm outlet air discharges 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.
REMKO BL Installation inside buildings ■ Ensure that heat can dissipate adequately when placing the outdoor component in cellars, lofts, 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 and which can compensate any additional pressure loss in ventilation ducts (figure 4).
Installation Oil return measures NOTE If the outdoor component is installed at a higher level than the indoor unit, suitable oil return measures must be taken. Usually, an oil pump bend is installed for every 2.5 metres of height difference. Oil return measures Outdoor component Unit installation The indoor unit is attached by means of a wall bracket, taking into consideration the air discharge side located in the lower part. 1.
REMKO BL Connection of quickrelease couplings The refrigerant pipes should be connected by the customer on the right-hand side of the outdoor component. The pre-filled refrigerant pipes are connected to the outdoor component by means of the quickconnector system. Once installed, the connections must be insulated to prevent vapour diffusion. The following instructions describe the installation of the refrigerant pipes of the indoor unit to the outdoor component.
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 = injection pressure blue = large valve = suction pressure Following connection of the quickrelease couplings, the connections are checked using leak detection spray and suitable devices for leaktightness. If leaks are found, the connections have not been made properly.
REMKO BL Control cables should be screened if laid in areas exposed to strong magnetic fields. ■ Details concerning the electrical protection of the system are provided in the technical data. ■ Connection of the outdoor component Proceed as follows to connect the cable: 1. Remove the cover from the unit. 2. Remove the side panel next to the terminals. Connecting the indoor unit 2 a 10 m long control cable are already connected to the indoor unit.

REMKO BL Before commissioning Following a successful leak check, the unit can be started again without the pipes needing to be pumped down to a vacuum. Perform the following checks prior to commissioning the unit for the first time and after any interventions affecting the cooling circuit.
Function test of the cooling and heating modes 1. Remove the protective caps from the valves. 2. Start the commissioning procedure by briefly opening the shut-off valves on the outdoor component until the pressure gauge indicates a pressure of approx. 2 bar. 3. Use leak detection spray or suitable devices to check that all the connections are tight. 4. If no leaks are found, fully open the shut-off valves by turning them anti-clockwise using a spanner. If leaks are found, remedy the faulty connection.
