Introduction Please control that the following documents have been delivered together with the unit: - Directions for assembly & use (this document) - CTS 600 directions - Electrical chart Should you have any questions on how to operate the system, contact your nearest Nilan dealer, who you can find at www.nilan.dk/dealers VPL 15/15T/25 is a ventilation unit with heat recovery. The unit can yield up to 325/700m 3 /h at 100Pa external back pressure. The unit can be equipped with different accessories e.g. hygrostat and filter box with pollen filter. Operating the unit is done with the CTS 600 control. The control has many functions such as menu based attendance, week programme, time controlled filter guard and adjustment of the velocity of the ventilator. (Directions for the CTS 600 control is described in another document delivered with the unit.) For accessories see page 23. We recommend that the system as well as the installation are adjusted/checked to ensure a healthy indoor climate and optimal operation. This document may be subject to change Side 3 of 23

Power supply Power supply including safety switch must be installed by an authorized electrician. The VPL 15/15T/25 unit must be connected according to the attached electrical chart. The unit is delivered with 1m test cable for the CTS 600 panel. The panel should be connected to the CTS 600 control in the unit with cable type 2x2x0.25mm 2 twisted in pairs. (Maximum length 50m). The CTS 600 panel must be placed dry and frost-proof. The panels integrated feeler prevents further cooling of the building if the primary heat-supply stops by stopping the ventilation if the panel feeler gets below a specific value. (Factory setting is 10 C; the value can be set from 1 C to 20 C.) Figure 1: CTS 600 control If a water post-heating element is installed, the control valve and circulation pump must be electronically connected as described in the provided wiring diagrams.

Assembly of VPL 15/15T/25 When mounting the VPL-unit future service and maintenance should be considered. There is required a minimum of open space in front and behind the unit of 600mm. The system s connection pieces and the pipes are connected with a flexible transition (flex pipes/sound flex pipes or the like). The system must be level due to the condense outlet. The condense outlet requires a clearance height of minimum 80-105 mm under the outlet connection piece. It is not necessary to re-insulate the system as it is delivered with a 20mm standard insulation. The system is low-noise and low-vibration. However, potential vibrations spreading from the system to the individual building parts must be taken into account. We recommend a minimum distance of 30 mm from building parts and other fixtures. To detach the system from the floor, we recommend that the system is placed on vibration absorbers as illustrated in figure 2 (See Accessories) 1 2 3 2 4 1: Vibration absorbers. 2: 22mm plywood/ chip board 3: Firm insulating batts 4: Wooden beam Figure 2: Mounting the VPL-Unit This document may be subject to change Side 5 of 23

Condensation drain / water seal The VPL unit is delivered with a 20mm condensation drain. (PVC, GF-fittings). The drain is placed under the discharge. The condensation drain should be carried with an even inclination of at least 1 cm per meter, frost-proof to the nearest outlet. The overflow from the safety valve should also be carried to the nearest outlet. To avoid frost problems it can be necessary to supply the condensation drain with a heating cable. It is the plumbers responsibility to secure the drain. When the system is running, there can be a vacuum of up to 500Pa (corresponding to 50mm water column) in the outlet. For this reason, the difference in height in the water seal must be minimum 50mm. This means that the first bend of the water seal must be at least twice as long in order for the system to be able to dispose of the condense water (see figure 3). The condensation drain must be airproof from the unit to the water seal in order for the condensation water to be let away from the unit. If the condensation drain is not airproof false air will be sucked in to the unit and the water will stay inside the unit. The water seal can dry out and avoid the water from running out of the unit. Therefore the water seal should be tested regularly and refilled with water if necessary. An elevated height of the water seal will reduce the need for refilling with water. Ø20 mm drain min. 50 mm. VPL min. 50 mm. min. 112,5 mm Figure 3: Condensation drain / water seal The water seal should be tested as described below. (the unit must be connected to the ducting and the front door should be closed): The condensation tray is filled with water and the unit is started at the highest ventilation step. The unit should run for a couple of minutes. Check that the condensation tray is empty when the test is finished. This document may be subject to change Side 6 of 23

Ducting We recommend that there are used ducts and fittings with rubber packing that meet sealing class B and that the connections between the unit and the ducting are made with 1 metre sound absorbing flexible transitions as regards sound reduction. The ducts should be shortened with a hacksaw or an angle grinder and laid out according to the working drawing. The ducts are typically laid out on the main beam of the truss frame and are secured with hole belts or they are being hanged in assembly belts. Please avoid any unnecessary area reductions and breaks of the ducting. The ducts should be insulated in some cases with the ordinary attic-insulation. All ducts should be insulated with 100mm mineral wool to avoid heat loss and condensation. This also applies for flexible transitions. It is recommended that the insulation is carried out with 2 layers of 50mm. If the ducts are laid out in an unheated room it will cause condensation problems if the unit are turned off for a longer period of time as the hot air from the heated room will rise to the ducts and cause condensation which can cause damp problems. Loft insulationmaterial Duct Granulate Figure 4: Insulation of ducting The discharge duct is leading the exhaust air away either above the roof or through the outer wall. It is important that the roof cowl has at least the same open space as the duct leading to the roof cowl. A reduction at this place will cause an unnecessary pressure drop which can lead to a reduced ventilation output. The holes for the inlet- and exhaust valves should be cut according to the mounting-frame for the prescribed valve. The frame for the valve must be secured with screws before placing the valve in the frame. The valves are placed in accordance with the size, construction and use of the room. As an example we would not recommend placing an inlet valve just above people with sedentary work because the inlet air in some cases would be experienced as a draught.

Heating surface, water Connecting the heating surface must be done by an authorized plumber. If the unit is placed outside or in a cold location the installation must frost secured. The heating unit is delivered as accessory and consists of: electrical box with LMC200-PCB, heating surface with temperature sensor T9 and frost-protection B3, actuator and regulating valve. The heating surface is to be installed in the inlet ducting just after the VPL unit. The heating surface must also be activated in the CTS 600 control as described on page 13. The mixing loop can be constructed as suggested below. The heating surface should be connected, scavenged and checked for any leakages before starting the unit. The dirt-catcher should be checked and cleaned after a thoroughly flushing of the system. 3 1 M 2 Heating surface Flow Air flow T9 Return B3 Note that the temperature sensor T9 and frost-protection B3 is placed at the heated side of the heating surface close to the return connection.
