The responsibility for maintaining the heat pump lies with the owner/user. 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.
Instructions can be downloaded from Nilan’s website: http://www.nilan.dk/en-gb/frontpage/download If you have questions regarding installation of the unit after having read the instructions, contact your nearest supplier of Nilan products, who can be found on www.nilan.dk/en-gb/frontpage/download/ dealers.

If the water trap dries out, air will be sucked into the unit and condensate water will not be able to drain. This will cause water damage. Nilan’s water trap contains a ball that ensures that no air is sucked into the unit and that condensate water can drain freely.
To make it easy to service the unit in the future, we recommend that you fit a flexible connection between the unit and the duct system. Nilan's flexible sound damper absorbs sounds effectively from both the duct system and from roof stacks.
Combi 302 Polar Top (English) BY NILAN Set up Installation Positioning of the unit ATTENTION When positioning the unit, you should always consider future services and maintenance. It must be easy to change filters, and it must, for instance, be possible to remove the heat exchanger, and to replace fans or other components.
Electrical installation Electrical connections Safety ATTENTION All work must be carried out by qualified persons and in compliance with existing legislation and regulations. ATTENTION It is important that the power is off, if you do work to the electrical components of the unit. It is important to check that wires are not damaged or squeezed during connection and use.

Combi 302 Polar Top (English) BY NILAN Electrical connections unit Power supply CAUTION The power supply, including a safety switch, must be installed by an authorized electrician. A power cable for connection to a power socket is included. It is important that the unit is earthed.
Electrical connection accessories Connection to user selection and Modbus User selection: Connection to user selection can be used, for instance, for controlling a cooker hood. This happens via a potential free contact in the cooker hood that sends a signal to the unit, which, in turn, increases ventilation when the cooker hood is on.
Combi 302 Polar Top (English) BY NILAN Electrical after-heating element An after-heating element is necessary if you want to control the supply air temperature. The electrical after-heating element can be purchased for installation in the supply air duct. The required sensor and connectors for the unit are included.
External heating control system The unit can control an external heat supply, such as electric radiators or an underfloor heating system. The unit monitors the room temperature and blocks the external heat supply when heating is not needed. If, through ventilation alone, the unit is unable to heat the room to the temperature you want, the external heat supply will be released until the room temperature has increased to the desired level.
INFO Nilan offers a water trap with a ball. The ball ensures that no air blows into the unit through the condensate drain if the water trap dries out. This ensures that water in the condensate tray can...
Combi 302 Polar Top (English) BY NILAN Plumbing connection - accessories Water trap with ball (option) Connection options with Nilan’s water trap: 1. Water trap with Ø32 mm reducing fitting 2. Reducing fitting for Ø20 mm 3. Reducing fitting for ¾" RG 4.
Nilan offers flexible Sound Flex tubes that provide a flexible connection between the unit and the duct system, but also reduce the sound transmission from the unit to the duct system.
Combi 302 Polar Top (English) BY NILAN Extract air Install exhaust air valves in rooms that generate humidity. Place them strategically where they can extract humidity most effectively. Rooms that generate humidity: • Bathroom • Lavatory • Kitchen • Utility room Supply air Install supply air valves in living areas.
Balancing Important information ATTENTION To ensure the ventilation system operates optimally, it is important that it is balanced correctly. We recommend that experts do this. It is important to measure the total supply air and the total extract air. The system must have a minimum vacuum, which means it must draw out more air than it blows in.
