5-4. 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.
N OT E
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.
