10-7. Taping the Tubes
(1) At this time, the refrigerant tubes (and electrical
wiring if local codes permit) should be taped with
armoring tape in 1 bundle. To prevent the con-
densation from overflowing the drain pan, keep
the drain hose separate from the refrigerant
tubing.
(2) Wrap the armoring tape from the bottom of the
outdoor 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. 10-10)
(3) Clamp the tubing bundle to the wall, using 1
clamp about every 3 feet.
Do not wind the armoring tape too tightly since this will
decrease the heat insulation effect. Also ensure that
the condensation drain hose splits away from the
bundle and drips clear of the unit and the tubing.
10-8. 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. 10-11)
