Page 5: Starting The External Unit
Compact P / Compact P Polar - AIR "RS" (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 unit Nilan’s units consist mainly of recyclable materials. They must, therefore, not be mixed with household waste, but must be delivered to your local recycling center for disposal. Heatpump Concerning disposal of units with heat pumps, it is important to contact the local authorities for information about correct handling of these. -
Page 7: General Information Introduction
If you have questions regarding installation of the unit after having read the instructions, contact your nearest dealer of Nilan products.
