Left-side tubing

(SAP-KMRV74EH, KMRV94EH, KMRV124EH, 

KMRV76EH, KMRV96EH, KMRV126EH, 

KRV184EH, KRV244EH, KRV186EH, KRV246EH)

(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. 38a)

(2) Switch the drain hose and drain cap.

Switching drain hose and drain cap

(a) Locate the drain hose and the drain cap. 

(Fig. 39a)

(b) Remove the screws fastening the drain hose

on the right side, and pull out the drain hose

to remove it. (Fig. 39a)

(c) Apply moderate force to pull off the drain cap

on the left side. (If you cannot pull it off by

hand, use a long-nose pliers.)

(d) Reattach the drain hose to the left side and

the drain cap to the right side. (Fig. 40a)

Drain hose

Slide the drain hose fully onto the drain pan outlet

until the drain hose edge is pushed into the insu-

lation. Check that the screw holes in the drain

bracket and the drain pan outlet are aligned and

securely in contact, then fasten them with the

screw. (After attaching the drain hose, check that

it is attached securely.) (Fig. 40c)

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. 40a and 41a)
