(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.
NOTE
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.
