Indoor Unit Connections
Removing the Indoor Unit Bottom Cover (HEV2 Only)
To access the indoor unit piping port connections, and
to make the indoor unit installation procedure easier,
it is recommended that the bottom cover be removed
first.
1. Unsnap the bottom cover at its top left and right
sides (Location 1).
2. Unsnap each of the three (3) or four (4) small
C-hooks located in the middle of the bottom cover
(Location 2). Number of C-hooks present depends
on model of indoor unit.
3. Lift the three (3) to four (4) hinges on the bottom
cover up and out of the channels molded to the
left, right, and middle of the indoor unit (Location
3). Number of hinges present depends on model
of indoor unit.
4. Set aside the bottom cover to re-install after all
procedures are complete.
1. Unsnap the piping / drain hose holder (L-bracket) out from the indoor unit chassis. Prop 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.
