5-4. Taping the Tubes
(1) At this time, the refrigerant tubes (and electrical wir-
ing if local codes permit) should be taped together
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 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.
(3) Clamp the tubing bundle to the wall, using 1 clamp
approx. each ft. (Fig. 5-10)
NOTE
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.
5-5. 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. 5-11)
