MOUNTING AND SETUP
• Fans are designed for horizontal mounting on a flat roof directly above an air duct or a ventilation shaft.
• In order to avoid ingress of water and snow into the ventilation duct, it is possible to install a fan on the mounting frame.
• The fan is connected to the ventilation duct by means of a counter flange, which is attached directly to the fan base.
• The fan base has holes for fixing bolts that attach the fan to a stationary even surface or to a mounting frame.
• In the models TOWER-V 220 2E, TOWER-V 225 2E, TOWER-V 225 4E, TOWER-V 310 4E, TOWER-V 310 4D, TOWER-V/TOWER-H 500 6E,
TOWER-V/TOWER-H 500 4D, TOWER-V/TOWER-H 500 6D, TOWER-V/TOWER-H 630 6D, TOWER-V/TOWER-H 710 6D the counter flange
is attached together with the fan inlet ring.
• A mounting frame, a counter flange and mounting bolts are not included in the delivery set and must be purchased separately.

• The unit is rated for connection to power mains with the parameters specified in the "Technical specifications”section, according to
the wiring diagram.
• The connection must be made using insulated conductors (cables, wires). The actual wire cross section selection must be based
on the maximum load current, maximum conductor temperature depending on the wire type, insulation, length and installation
method.
• The unit should be connected to the fixed wiring system in compliance with current regulations.
Connection to power mains should be made inside the terminal box located on the fan casing, according to the wiring diagram and
terminal designation. The terminal designations are shown on the label inside the terminal box. Fan electrical data is shown on the
label on the fan casing.
Depending on modication, the fan motors can have no in-built thermal protection. This should be taken into account when
choosing a motor starter or a contactor.
