(2) Wrap the armoring tape from the bottom of the out-
door unit to the top of the tubing where it enters the
wall. As you wrap the tubing, overlap half of each
previous tape turn. (Fig. 36)
(3) Clamp the tubing bundle to the wall, using 1 clamp
approx. every 4 ft.
Do not wind the armoring tape too tightly since this will
decrease the heat insulation effect. Also be sure the con-
densation drain hose splits away from the bundle and
drips clear of the unit and the tubing.
4-6. Finishing the Installation
After finishing insulating and taping over the tubing, use
sealing putty to seal off the hole in the wall to prevent
rain and draft from entering. Fig. 37 shows refrigerant
tubing taped separately from the drain hose.
