Indoor Unit Connections

Removing the Indoor Unit Bottom
Panel
To access the indoor unit piping port connections, and to make the
indoor unit installation procedure easier, open the front panel, and
remove the bottom panel first.
1. Fully open the front panel.
2. The bottom panel has plastic "pins" that attach to the indoor unit
at several connection points. The number and position of the con-
nections vary depending on the model of indoor unit.
3. Hold the center of the bottom panel, and pull it towards to disen-
gage the pins, releasing them from the connection points.
4. Pull both sides of the bottom panel out to release the pins from
the connections, being careful not to damage the bottom panel or
scratch the main horizontal vane. Set aside the bottom panel to
re-install after all procedures are complete.
Accessing and Positioning the Indoor Unit Piping
1. Unsnap the piping holder from the back of the indoor unit. Prop it open between the
indoor unit frame and installation plate to separate the bottom of the indoor unit from the
wall. This will allow for more working space.
2. 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.
• Do not bend the piping directly 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.
