6.4.1 Assembly the Topvex SoftCooler
Fig. 7 Left hand unit
Make sure that the sealing stripes and faces of sealing in-between the unit half are undamaged.
1. To get access to the upper mounting screws (M8) remove the rectangular covering plate on top of
the Topvex SoftCooler.
Place the Topvex SoftCooler in-between the two air handling unit parts and carefully push them together.
2. When the three parts are completely joined together: Screw the upper and lower mounting screws
that joining the parts.
3. Connect the electrical wiring in the Topvex TR electrical box. Assemble the electrical fast couplings and
the transparent air tubes on each side of the Topvex SoftCooler make sure that they are on the right
place by reading the labelling.
Assemble the plate "A" figure figure 6, heat exchanger, extract- fan and filter.
6.4.1.1 Duct connections
When Topvex SoftCooler have been joined together with the two air handling unit parts it is in total 5 duct
connections on top of the unit: Outdoor air, Supply air, Extract air and 2 Exhaust air. Duct connections can
be done on two different ways, with or without a by-pass-function for the exhaust air.
For duct connection without by-pass function on the exhaust air only 4 duct connections are used. The
exhaust air duct are then to be connected to the exhaust air duct connection on the Topvex SoftCooler
module. The exhaust air duct connection on the air handling unit must be locked with the Topvex
SoftCooler included locking plate.
For duct connection with "By-pass" function on the exhaust air all 5 duct connections are used. The
exhaust air duct are then to be connected both to the Exhaust air duct connection on the Topvex SoftCooler
module and to the one on the air handling unit.
N.B. Motorized spring return dampers must be mounted on each exhaust air duct connection.
