Accessing and Positioning the Indoor Unit Piping / Connections

it open between the indoor unit chassis and installation plate to separate the bottom of
the indoor unit from the wall. This will allow for more working space.

2. Remove the piping port cover.
3. Position the piping by unfolding and bending the piping slowly
downward first as shown, then to the left or right (pre-chosen
following installation guidelines and application needs) as shown.
Secure piping with the piping holder.
• Do not bend the piping directly backwards or to the left or right
sides without bending it downward first; this will damage the indoor
unit piping.
•
Do not forcibly press the refrigerant piping onto the bottom
frame or the front grille; this will damage the indoor unit piping and
/ or indoor unit frame.
• Ensure the piping is straight. Do not kink the piping; this will
damage the indoor unit and piping.
