I Left-side tubing
(SAP-KRV96EHDS)
(1) Lead the tubing and drain hose through the wall,
allowing sufficient length for connection. Then
bend the tubing using a tube bender to make the
attachment. (Fig. 38b)
(2) Switch the drain hose and drain cap.
Switching drain hose and drain cap
(a) Grasp the corners of the bottom left and right
indoor unit covers, and press down on the
bottom while lifting each cover up to remove
it. (Fig. 39b)
(b) Locate the drain hose and the drain cap.
(Fig. 39c)
(c) When disconnecting the drain hose, remove
the drain fitting from the stopper, then check
the position of the drain fitting on the end of
the hose, and turn the hose while pulling to
remove it. (Fig. 39d)
(d) Screw the drain hose all the way inside. Turn
the hose so that the protruding part of the
drain fitting comes below the stopper as
shown in the figure. It will be easy to insert
when water is added. (Fig. 39d)
(e) Align the tabs of the removed cover with the
grille tabs, and then lower the cover to install
it.
Drain cap
Use a Phillips screwdriver to push the drain cap in
firmly. (If it is difficult to push in, wet the cap with
water first.)
(3) Install the indoor unit on the rear panel.
(4) Connect the tubing and wiring led inside from out-
doors.
(5) After completing a leak test, bundle the tubing
together with armoring tape and store it inside the
tubing storage area at the back of the indoor unit
and hold it with clamps. (Figs. 40d and 41b)
