FLEXYII_WSHP-IOM-0909-E Page 22
CAUTION:
- An approach ramp must be installed if the unit’s installation requirements tell that it's
necessary to reach the main switch. This recommendation is valid for installations in
general and in particular for return and curbs. It’s also valid to reach other parts of the
unit: filters, refrigerant circuit, etc…
- It’s advised to fix curbs and roofcurbs to the unit.
As levels are adjustable, observe the following
recommendations when installing the equipment
Above all, ensure that all the adjustable returns are facing
outward (“1” figure 4). They are usually turned inside-out
for transport.
Place the roof mounting frame on the trimmer beam by first
lining up the inlet and the outlet opening. (“2”- figure 5)
After levelling the frame, secure the adjustable returns on
the trimmer.
It is important to centre the unit on the roof frame
