7-4. 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 pre-
vent 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. 7-12)
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.
7-5. Finishing the Installation
After finishing insulating and taping over the tubing,
use sealing putty to seal off the hole in the wall to pre-
vent rain and draft from entering. (Fig. 7-13)
