Suction Air Filter Servicing
Filter maintenance could be performed from right or left side of
the unit.
Remove filter support (x2 screws / each support) and pull out the
filter from the handle.
In those installations where the servicing space is narrow, the
filter could be bent (in three pieces) when pulling it out.

N O T E
• When design a duct, check to ensure that the Air volume is within
working range as indicate "Fan Performance Curve".
• If the Air volume is set outside working range, water-carry-over (drop
in the ceiling or into the room), noise increases, fan motor damaged
(high temperature), insufficient Cooling/Heating capacity, phenomena
can occur.
• Therefore design ducts and select the correct fan speed in order to
keep the unit running in the accepted working range.

C A U T I O N
The static pressure setting must be the same in both units.(There are 2
Electrical boxes, so connector change must be made in both of them).
