Using a crimping tool, compress the two points and flip it
over and compress another two points in the same location.
• The compression dimension should be 8.0.

CAUTION
• Make sure that the connection parts are not exposed
to outside.
• Be sure to use insulation tape and a contraction tube
made of approved reinforced insulating materials that
have the same level of withstand voltage with the
power cable. (Comply with the local regulations on
extensions.)
WARNING
• In case of extending the electric wire, please DO NOT
use a round-shaped Pressing socket.
– Incomplete wire connections can cause electric shock
or a fire.
Step 14 Increasing Fan Speed
If external static pressure is too great(due to long
extension of ducts, for example), the air flow volume
may drop too low at each air outlet. This problem can be
solved by increasing the fan speed using the following
procedure.
1
Remove the screw on the electrical component box and
remove the cover plate.
