If you have questions regarding installation and operation of the unit after having read the instructions, please contact your nearest Nilan dealer. A list of Nilan dealers is available on www.nilan.dk. ATTENTION The unit must be started up immediately after installation and connection to the duct system.
- Page 4 The heat pump has a reversible cooling circuit, which means that the cooling circuit can be turned and it can cool the supply air in the summer. Combi 400 Polar Top can cool the supply air by up to 10 ° C in relation to the outdoor air. Due to the low air exchange, usually 1/2 time per hour, it will not act as an air conditioning system.

- Page 7 You then have to adjust the duct system yourself with a connection to the cooker hood. Cooker hood filter box If the extract air needs extra filtration, Nilan can supply a Cooker hood filter box. This can provide extra protection of the ventilation unit if you connect a cooker hood that has not got good filters.
- Page 8 Every autumn it is therefore important to check that there is water in the water trap. However, if you install a Nilan water trap with ball, the ball will ensure permanent function of the water trap. This saves you refilling the water trap manually every autumn to ensure that it works.
- Page 9 If you install the ventilation unit outside the climate screen, it is important to protect the condensate drain from frost. Nilan can supply an external heating cable that you run along the exterior of the condensate drain before insulating it. This way you will have a frost free condensate drain that does not get blocked. The heating cable has an integral thermostat that regulates the level of heating in accordance with the temperature of the surroundings.
- Page 10 Set-up Mounting Positioning the unit ATTENTON A free space is recommended in front of the ventilation unit of at least 60 cm. It must be easy to replace filters and e.g. it must be possible to remove the exchanger, re- place the fan or other components.
- Page 11 Electrical installation 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.
- Page 12 Connecting to the internet Using an RJ45 LAN cable, you connect the gateway to a router with an internet connection (the cable is not supplied by Nilan). The con- nection from the gateway is located at the top of the ventilation unit.
- Page 13 (according to the wiring diagram), where the wires from the front-connection are removed. Nilan offers a connection cable with RJ12 plugs of 10 m and 20 m, respectively. It is also possible to customize a cable up to 50 m in length.
- Page 14 ELectrical connection accessories User selection 1 User selection 1 is connected via the 8-pin plug mounted on top of the unit. The user selection functions are used to override normal operation. The input signal must come from a potential-free switch. When closed, the function is activated with the settings selected in the control panel under Service / User selection.
- Page 15 Electrical after-heating element If you want to control the supply air temperature, you will need an after-heating element. You can purchase an electrical after-heating element for installation in the supply air duct. It comes with the required sensor and con- nection to the ventilation unit.
- Page 16 Electrical after-heating element for mounting on top or on the side If you want to control the supply air temperature, you will need an after-heating element. You can purchase an electrical after-heating element for installation in the supply air duct. It comes with the required sensor and con- nection to the ventilation unit.

- Page 18 Compact. This makes instal- lation easier. ATTENTION The expansion PCB and the connections must be installed by a certified electrician. The expansion PCB is an accessory to the CTS602 circuit board. Nilan does not supply external components.
- Page 19 User selection 2 User selection 2 offers you the same options as User selection 1. In addition, you get the option of a relay output that can control e.g. a damper or whatever external function you may need to control. The 8-pin plug and the terminal block are located at the top of the unit.
- Page 20 DTBU (damper option) If it is desired to run the cooker hood over the ventilation system, it may in some cases be difficult to get enough air for the cooker hood. To solve that challenge, an EM-box solution can be used. However, if there is not enough space in the installation for an EM box, you can alternatively connect a DTBU damper in the duct system, which has the same function, except that it does not have a built-in dirt filter.
- Page 21 Joint alarm It may be difficult to notice alarms if the unit is located in a place where access is difficult or infrequent, and if the control panel is locat- ed in the same place. An external alarm indicator in the form of an electric bulb or an acoustic signal can be connected to the ventilation unit and announce when an alarm occurs.

If the water trap is placed outside the climate screen, it should be protected against frost. Ø20 mm min. 50 mm min. 50 mm Illustration of connection at the bottom of the unit ATTENTION There is positive pressure in the condensate drain in the ventilation unit and it is therefore not necessary to install a wa-...
- Page 23 This is to avoid vibrations from the unit being transmitted to the duct system. It will also make it easier to move the unit, which may be necessary during future services of the unit. Nilan can supply Soundflex tubes that you can use as flexible connections between the ventilation unit and the duct system. They will also reduce sounds from the system considerably.
- Page 24 Extract air Install the extract air valves in high-humidity rooms and place them strategically where they can extract humid and vitiated air from the dwelling/building most efficiently. High-humidity rooms are, for example: • Bathroom • Lavatory • Kitchen • Utility room Supply air Install supply air valves in living areas.
- Page 25 Balancing Important information ATTENTION To ensure the ventilation system operates optimally, it is important that it is balanced correctly. We recommend that ex- perts 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 draw out more air than it blows in.
