9-4. 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 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.

(3) Clamp the tubing bundle to the wall, using 1

clamp approx. each meter. (Fig. 9-12)

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.

9-5. 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. 9-13)
