REFRIGERANT PIPING CONNECTIONS
Piping to Indoor Unit (HSV3)
To access the indoor unit piping port connections, terminal block, and to make the indoor unit installation procedure easier, it is recommend-
ed that the bottom cover be removed first.
1. Pull the screw cap(s) at the bottom of the indoor unit.
2. Unscrew the two (2) or three (3) screws (depending on the indoor unit model) at the bottom of the chassis cover.
3. Remove the chassis cover, being careful not to scratch the main horizontal vane.
4. From the rear of the indoor unit, pull the tubing holder away from the unit.
5. Remove the pipe port cover.
6. Position the tubing by unfolding the tubing and bending the tubing slowly downward first, as shown below.
Figure 52: Removing Chassis Cover from Indoor Unit (HSV3).
Bending the tubing directly left or right, without
bending downward rst, may cause damage.
