Installation Instructions sales@ventair.com.au | www.ventair.com.au Multivent Continuous Extract Ventilation INSTALLATION Position the unit, taking into consideration the position of the rooms to be ventilated, the exhaust position and the electrical services. Ensure there is adequate access for installation and maintenance. If the unit is sited in the heated void of the dwelling a condensate drain should not be necessary. When sited in a roof cavity, consideration should be given to fitment of a condensate drain. Alternatively the unit and ducting can be externally insulated to minimize condensation within the units housing. To reduce the system resistance in your duct system, and therefore lower the speed, power consumption and noise of the fan, follow these guidelines: · Keep the length of duct runs to a minimum, particularly the exhaust duct run. · When using the flexible ducting in the kit, make sure that it is fully extended and not crushed, sagging or torn. · Try to minimize the use of diffusers/valves by having similar length duct runs to the inlets. · The bend radius (measured to the inside of the bend), should be at least 1x the duct diameter. · Avoid having any bends, filters or other obstructions within 250mm of the fan inlets and outlet. Maximum length of flexible ducting Duct Supports Sleeve Interior Grille Airflow Sealant Cavity Exterior Grille Airflow Minimum radius = diameter of ducting Peaks and troughs Preferred flexible ducting route Restrictions Securely mount the unit through the mounting holes on the casing using appropriate fixings (not supplied) for the mounting substrate. Fixings to be capable of securing 4x the weight of the unit. Unit weight: 4.1kg. Anti-vibration mounts, acoustic mats or rubber bushes can also be used. Installation example shown below. To maintain the IPx2 rating of the unit, the unit must not be mounted with the cover removal slots facing upwards (as indicated by the red arrows), or at an angle where they are visible from above. All other orientations are acceptable. Main power connections Low voltage connections Installation Instructions Specifications are subject to change without notice. sales@ventair.com.au | www.ventair.com.au Page 3 Distributed by Ventair Pty Ltd Multivent Continuous Extract Ventilation INSTALLATION Multivent Continuous Extract Ventilation INSTALLATION · Mount the 125mm duct joiner (DCT0037) to the exhaust port of the MultiVent. · Fit the 150mm to 125mm reducer (DCT2066) to the 125mm duct joiner and tape both joints using the supplied duct tape. As per the picture above try to position the MultiVent fan housing in a location central to all of the rooms that you are planning to extract from. Also remember that the unit could create noise and should be mounted away from bedrooms. Mount the MultiVent using the 4 mounting points. Bear in mind that the exhaust (main extraction) uses 150mm aluminium foil ducting and a 150mm weather proof cowl (not supplied with VMEV) but available separately. Each VMEV-KIT contains 3 x 6m lengths of 125mm aluminium foil ducting for the extraction points. · Cut a hole to the required duct valve size in the necessary locations in the Bathroom, Toilet, Laundry or Kitchen (if applicable and a minimum 2m away from the cooking top). · Carefully pull the aluminium 125mm duct through the freshly cut hole at each location. · Fit the 150mm aluminium foil ducting (VAD150) to the 150mm waterproof cowl (V150WPC) and tape it to the spigot. · From outside of the building cut a 150mm (minimum) hole in the outside wall of the home and push the 150mm ducting through the hole. · Fit the waterproof cowl to the building exterior and then from the roof space pull the ducting taut and tape it off at the 150mm to 125mm reducer. · Extend each length of the 125mm aluminium foil ducting pulling it taut and tape off the three extraction points to the MultiVent unit. · Install electrical wiring as per page 3 of the instruction manual. · Extend the 125mm aluminium foil ducting over the duct valve spigot and use duct tape provided (in VMEV-KIT) to secure in place. · Once the duct is firmly secured in place push the duct valve up into the ceiling ensuring the three spring clips evenly align with the edge of the cut out. · Use even upward pressure on the face of the duct valve, allowing it to pull itself up into place. Complete the other two rooms following the same instructions. Page 4 Distributed by Ventair Pty Ltd Specifications are subject to change without notice.

LS input active more the 20 minutes Unit will Boost after 20mins. Once LS input is removed, fan will run at user selected speed for 20 minutes plus the set overrun time (if over run is enabled). The above applies to all LS inputs. The times are not adjustable by the user. Delay On A delay can be set so that the unit will not respond to an input until after the set delay has elapsed, applies to LS inputs only. Overrun Timer The unit can be set to run for a defined period after the input is removed, applies to LS inputs only. Humidity Rapid rise* Rapid Rise humidity response functions to detect rapid rises in humidity when the ambient %RH is under the threshold setting. If a rapid rise is detected the fan will boost until the humidity lowers again. Humidity Ambient response* When ambient response is enabled the threshold set point is modified based on the ambient temperature. This helps to prevent nuisance boosting of the unit as temperatures changes during the day. Humidity Threshold* The unit will boost when the RH is above the threshold set point. Analogue inputs Both analogue inputs have adjustable low and high trigger voltages within the 0-10V range. The response to being above or below either of the threshold voltages is user settable. Note: The display doesn't show a decimal point, for example at threshold voltage of 5.2V, is displayed as "52" on the unit. Digital Inputs The unit can be set to change speed (selectable), based on whether the digital inputs are above or below the threshold voltage. See the table of Low Voltage Connections for details. Display Lock To protect the settings on the MultiVent unit a pin code can be enabled via the main menu. Once the lock function has been enabled the Pin code can be set. The 3-digit pin is A to F, 0 to 9, and the default is LoC. Page 8 Distributed by Ventair Pty Ltd Specifications are subject to change without notice.

The Multivent will utilise Humidity Rapid Rise in its response and the 2 larger rooms (Bathroom and Laundry) will also provide a PURGE speed function if these 2 rooms are switched on together. Before commencing please ensure that all power is OFF and ensure that it is electrically safe before starting. Wire the 230VAC connections as per the diagram below. Wire mains connections from a suitable source (lighting circuit) or add a new dedicated circuit from an RCD protected 10A MCB with the cable to L (live - BROWN), N (neutral - BLUE) and E (protective earth GREEN/YELLOW). Wire a 230V connection from a switch located in the Bathroom that could be either a dedicated FAN switch (or a connection from a LIGHT switch) and connect the L (BROWN) wire back to LS1. Do the same from a switch located in the Laundry and connect the L (BROWN) wire back to LS2. Hardwire a NEUTRAL LINK (BLUE or BLACK) from the N (neutral - BLUE) mains connection to the connection labelled NS (neutral switched). L N E LS1 LS2 NS L N NEUTRAL LINK From Bathroom From NS Laundry Multivent Continuous Extract Ventilation For the toilet the Multivent will use its Extra Low Voltage connections for control. Using a short piece of wire connect a 0.5mm (or similar sized wire) from the GND terminal at the RS485 connection to the COM terminal adjacent to DIN 2 (digital input 2) + connector. Using a twin red TPS cable connect one RED core to the + connector at DIN 2 and connect the other RED core to the 5V terminal at the RS485 connection. Run the other end of the cable to the toilet FAN switch and connect the 2 red cores to the C (common) and the normally open (usually labelled 1) connections at this switch. See diagram below. RED RED C 1 TOILET Using instructions from the section "UNIT ADJUSTMENT" change LS1 from Low to BOOST With this completed the MultiVent once switched ON will operate in NORMAL speed (35%). When the Bathroom FAN switch is turned on the MultiVent will operate at BOOST (70%) speed clearing away steam and humidity. If the Laundry FAN switch is turned on the MultiVent will operate at BOOST (70%), and if both Bathroom and Laundry FAN switches are turned on together the MultiVent will operate at PURGE (100%) speed helping to clear away steam and humidity. The toilet FAN switch will also turn the MultiVent on to BOOST (70%). Please note that only having the 2 larger rooms (Bathroom and Laundry) switched on will activate PURGE (100%) speed.
