Tubing Insulation

●Thermal insulation must be applied to all unit tubing, including distribution joint (purchased separately).

*For gas tubing, the insulation material must be heat resistant to 248°F or above. For other tubing, it must be heat resistant to 176°F or above.

Insulation material thickness must be 25/64" or greater. If the conditions inside the ceiling exceed DB 86°F and RH 70%, increase the thickness of the gas tubing insulation material by 1 step.

Taping the flare nuts

CAUTION

If the exterior of the outdoor unit valves has been finished with a square duct covering, make sure you allow sufficient space to use the valves and to allow the panels to be attached and removed.

Sealer (supplied)

Wind the white insulation tape around the flare nuts at the gas tube connections. Then cover up the tubing connections with the flare insulator, and fill the gap at the union with the supplied black insulation tape. Finally, fasten the insulator at both ends with the supplied vinyl clamps. (Fig. 6-8)

Insulation material

The material used for insulation must have good insulation characteristics, be easy to use, be age resistant, and must not easily absorb moisture.

	CAUTION	After a tube has been
	CAUTION	insulated, never try to bend it


		into a narrow curve because it
		can cause the tube to break or
		crack.
