When installing "CL" mod-
CAUTION
els, insulate both wide and
narrow tubes.
When outdoor temperature is low, condensation can
also form on a narrow tube. So always insulate both
wide and narrow tubes.
8-7. Taping the Tubes
After a tube has been
insulated, never try to bend
CAUTION
it into a narrow curve, as this
may cause the tube to break
or crack.
(1) At this time, the refrigerant tubes (and electrical
wiring if local codes permit) should be taped 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
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. (Fig.8-10)
(3) Clamp the tubing bundle to the wall, using 1
clamp about every 3 feet.
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.
8-8. 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. 8-11)
