6-4. 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
the 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 ft. (Fig. 6-10)
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.
6-5. 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. 6-11)
