● 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. No duct connection If one or more of the spigots is not connected to a duct: Fit a pro- tective net to the spigots with a maximum mesh width of 20 mm.

Page 33 Maintenance 3004793-2016-10-03 Summary of parts in There is a difference in the sequence for removing counterflow heat exchangers, the heat exchanger depending on whether the VEX is a left or right-hand unit. One a left-hand unit the section heat exchanger to the left is removed first, while on a right-hand unit the right-hand heat exchanger is removed first.
Page 34 Maintenance 3004793-2016-10-03 VEX370R Step Action Start by opening the door to the fan sec- tion (right-hand section for a left-hand unit) and release the 6 tensioners: turn the tensioner clockwise 7 times. Loosen the finger screws on the brack- et. Push the bracket to one side and re- move it.
Page 35 Maintenance 3004793-2016-10-03 Step Action Remove the sealing profile in front of the heat exchangers (unhooks). Remove the sealing panel between the heat exchangers (pull the handle). Remove the first heat exchanger. NB: A single heat exchanger weighs 19 kg. Push the other heat exchanger to the side and remove it also.
Page 36: Servicing And Cleaning
Maintenance 3004793-2016-10-03 Step Action Use the first of the two panels on the in- side of the door in the heat exchanger section as an underlay for the next row of heat exchangers. Lay the panel at the side from which the heat exchanger is to be removed.
