Attaching the FAN CUSHION
When you change the EXHAUST FAN, affix a new FAN CUSHION to the new EXHAUST FAN.
Pay attention not to let the FAN CUSHION protrude from the outline of the frame of the
EXHAUST FAN.
Margin: 0 to 1mm
Stick the FAN CUSHION so that both ends do
not hang over the gap. Otherwise, a rib of the
BALLAST HOLDER cannot come into this gap
when attaching the EXHAUST FAN to it.

Insert the EXHAUST FAN into the BALLAST HOLDER facing its surface with the cable to the
BALLAST HOLDER.
