4. Taping the Tubes

(1)At this time, the refrigerant tubes (and electrical wiring if local codes permit) should be taped together with armoring tape in 1 bundle. To prevent condensation from overfl owing 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.

(3)Clamp the tubing bundle to the wall, using 1 clamp approx. each meter (3 feet). (Fig. 1-120)

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. Finishing the Installation

After fi nishing 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. 1-121)
