Page 6: Application
Standard 1.2 Application Comfort ventilation EXHAUSTO VEX is used for comfort ventilation tasks. Operating temperature range for the unit - see section "Technical data". Prohibited uses The VEX unit is not to be used to transport solid particles or in areas where there is a risk of explosive gases.
Page 7: Condensation Outlet
● heating/cooling losses Condensation Condensation in the ducts may occur when the exhaust/outdoor air has high hu- midity. EXHAUSTO recommends a condensation outlet is also fitted at the lowest point in the ducts. Outdoor air intake The outdoor air intake must be dimensioned with sufficiently low airflow to prevent rain and snow being drawn into the duct system.

Page 15 Handling 3004500-2016-01-14 To remove the fan unit Step Action Remove the fixing screw from the sliding rail, and release the ties on the motor cable. Pull the fan unit out to the stop (two screws) on the sliding rail. Dismount the motor cable from the motor control on the sliding panel and pull it towards the motor through the rubber grommets.
Page 16: Mechanical Assembly
After installation, check the VEX unit is completely level. 3.1.2 Installation on mounting base The EXHAUSTO mounting base enables the VEX unit to be installed correctly. The base is equipped with adjustable levelling screws, so that the air handling unit can be fitted horizontally on a surface that is not level ( +/- 20 mm per metre).
Page 17 Solution with HT Use HT pipe (HT, DN32, DIN4102), if the above solution is not employed (not sup- pipe plied by EXHAUSTO). If the VEX is erected on a mounting base, this will allow sufficient free height for installing a water trap.
