The air gap between the outermost vertical supports and the duct walls as well as between the
front bracket and the duct ceiling must be sealed using EPDM sealing profile (accessory). Cut
the EPDM sealing profiles to the desired length (channel height and channel width plus
allowance). Fix the EPDM sealing profiles to the outermost vertical supports and to the front
bracket using the clamping brackets and self-tapping screws #10 x 3/4" supplied. Tailor the
EPDM sealing profiles to the duct height and the duct width, then fix them to the duct walls
and the duct ceiling using the clamping brackets and self-tapping screws #10 x 3/4" supplied
(number of self-tapping screws to be used as required).
In place of the EPDM sealing profiles, sheet metal angles of stainless steel (not included in the
delivery) may be used for the sealing.
