    Always disconnect the power supply to the unit before opening the unit doors, for instance for installation, inspection, cleaning and filter change. 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 5: General Information Introduction

    If you have questions regarding installation of the unit after having read the instructions, contact your nearest dealer of Nilan products. You can find Nilan dealers on www.nilan.dk/en-gb/frontpage/ download/dealers. The purpose of these instructions is to advice the installer on correct installation and maintenance of the unit.

  • Page 6: Unit Type

    VPL28 has a reversible cooling circuit and it can therefore cool the supply air in the summer. As a standard, VPL28 is supplied with an ISO ePM1 65-80% (F7) filter in outdoor air and an ISO ePM10 (M5) in extract air.

    VPL28 (English) BY NILAN Accessories FU28 heat pipe An FU28 heat pipe raises the temperature of the outdoor air a fraction. This increases the efficiency of the heat pump considerably during the cold season. In most cases if you install an FU28 heat pipe, an after-heating element with a mixing circuit will not be necessary for the supply air to remain of reasonable temperature.

  • Page 10: Em-Box

    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.

  • Page 11: Set Up

    VPL28 (English) BY NILAN Set up Installation Positioning the unit ATTENTION When positioning the unit, you should always consider future services and maintenance. It must be easy to replace filters and it must be possible to replace, for instance, fans and 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.

  • Page 13: Control Panel

    VPL28 (English) BY NILAN Control panel HMI User panel The user panel is supplied with 1½ m cable. Connect the panel to the CTS602 control system in the unit using a CAT.5e cable (max. length 50 m). ATTENTION If you want a longer cable, use an ordinary LAN-cable, not a crossover cable, max. 50 m.

    Wall bracket Mount the HMI panel on the wall using the integrated wall bracket. The panel should be visible so it is possible to change settings and to monitor warnings or alarms regarding operation. The wall bracket is located at the back of Mount the bracket on the wall using 2 Click the RJ12 plug into place at the the panel.

  • Page 15: Electrical Connection Of The Unit

    VPL28 (English) BY NILAN Electrical connection of the 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 FU28 heat pipe Having an FU28 heat pipe installed before the unit will increase VPL28 COP (efficiency) considerably; especially at low outdoor temperatures. VPL28 FU28 Outdoor air Extract air The temperature sensor T1, T10 and the humidity sensor RH must be moved as illustrated. It is important that they are moved and placed before the heat pipe in order for the unit to operate correctly.

  • Page 17: External Electrical Pre-Heating Element

    VPL28 (English) BY NILAN External electrical pre-heating element If installing an FU28 heat pipe is not an option, you can purchase an external electrical pre-heating element in order to secure efficiency of the heat pump. Install the electrical pre-heating element together with the required temperature sensor in the outdoor air duct before the unit.

  • Page 18: Electrical After-Heating Element

    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. 0-10V 1x230V ~ 50 Hz max.

    VPL28 (English) BY NILAN Mounting of expansion PCB on CTS602 circuit board If you connect an expansion PCB to the CTS602 circuit board, you will be able to use user selection 2. Similar to user selection 1, user selection 2 allows you to override the functions of the unit via an external signal from a potential free contact.
  • Page 22 The expansion PCB is an accessory to the CTS602 circuit board. Nilan does not supply external components.

  • Page 23: Electrical Connection - Other

    VPL28 (English) BY NILAN Electrical connection - other 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.

  • Page 24: Fire Connection

    Fire connection You can connect a fire thermostat or an external fire automation system. It must be a closed signal, so that the unit will register that there is a fire if the signal is interrupted. NB! If you connect the unit to an external fire automation system, set the software: Service settings/ Restart/Fire.

  • Page 25: Plumbing Installation Condensate Drain

    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 drain off, which makes it unnecessary to check the condensate drain quite so often.

  • Page 26: Plumbing Connections - Accessories

    Plumbing connections - 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. Reducing fitting for ½" tube Dimensional drawing: All measurements are in mm.
  • Page 27 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.
  • Page 28 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. Place them strategically so they cause minimum discomfort. It is, for instance, not recommended that you install supply air valves in areas where people are inactive, as the supply air may be experienced as draughty.
  • Page 29 VPL28 (English) BY NILAN 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.
