CAUTION | Be sure to match refrigerant | |
tubing and electric wiring | ||

| units. |
IMPORTANT
To prevent heat loss and wet floors due to dripping of con-
densation, both tubes must be well insulated with a proper insulation material.
The thickness of the insulation should be a minimum 8 mm. (Fig. 17)

CAUTION
After a tube has been insulated, never try to bend it into a narrow curve, as this may cause the tube to break or crack.

(1)At this time, the 2 refrigerant tubes (and electrical wire if local codes permit) should be taped together with armoring tape. The drain hose may also be included and taped together as 1 bundle with the 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. 18)
(3)Clamp the tubing bundle to wall, using 1 clamp approx. every 120 cm.
NOTE
Do not wind the armoring tape too tightly, since this will decrease the heat insulation effect. Also, be sure the con- densation drain hose splits away from the bundle and drips clear of the unit and the tubing.
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. 19)
