Page 5: Starting The External Unit
Compact P / Compact P Polar - AIR (English) BY NILAN Safety Starting the external unit The external AIR unit is equipped with a compressor heater, which heats up the compressor prior to starting and in case of low outdoor temperatures. This facilitates start-up and extends the compressor’s service life. -
Page 6: Disposal
Disposal Ventilation system Nilan units mainly consist of recyclable materials. They should therefore not be disposed of with household refuse. Take them to your local recycling centre. Heatpump Concerning disposal of units with heat pumps, it is important to contact the local authorities for information about correct handling of these. -

• Installation instructions/Software instructions • User manual • Wiring diagram The instructions can be downloaded from the Nilan website: http://www.nilan.dk/en-gb/frontpage/ download If you have further questions on unit installation after reading the instructions, contact your nearest Nilan distributor, who can be found on www.nilan.dk/en-gb/frontpage/download/dealers. - Page 8 The energy-efficient and low-noise AIR air/water heat pump heats the home via floor heating or low- temperature radiators. It extracts energy from the outside air and functions at temperatures as low as -22 ºC. The heat pump has an electrical power supply to help it to function during very cold periods. The AIR unit has a reversible cooling circuit, which means that it can also be used to cool the home during the summer, using either the floor heating system or fan coils.
