Sanyo PNR-XS2432, XS1852 installation instructions Taping the Tubes, Finishing the Installation

Important

Because capillary tubing is installed in the outdoor unit, both the wide and narrow tubes of this air conditioner become cold. Therefore, to prevent heat loss and wet floors due to dripping of condensation water, both tubes must be well insulated with proper insulation material. The thickness of the insulation material should be a min. 8 mm (5/16").

7-7. Taping the Tubes

(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. 7-9)

(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.

7-8. 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. 7-10)
