Tube Dia.	Tightening Torque
6.35 mm	Approx. 15 - 20 N.m (1.5 - 2.0 kg.m)

9.52mm Approx. 35 - 40 N.m (3.5 - 4.0 kg.m)

12.7mm Approx. 50 - 55 N.m (5.0 - 5.5 kg.m)

10.2.5Insulation of Refrigerant Tubing

IMPORTANT

To prevent heat loss and wet floors due to dripping of condensation, both tubes must be well insulated with a proper insulation material. The thickness of the insulation should be a min. 8 mm. (Fig. 31, 32)

CAUTION

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

10.2.6 Taping the Tubes

•At this time, the 2 refrigerant tubes (and electrical wire if codes permit) should be taped together with armoring tape. The drain hose may also be taped together as 1 bundle with the tubing.

•Wrap the armoring tape from the bottom of the outdoor to the top of tubing where it enters the wall. As you wrap the tubing, overlap half of each previous tape turn. (Fig. 33)

•Clamp tubing bundle to wall, using 1 clamp approx. every 120cm.

NOTE Do not wind the armoring tape too tightly, since this will decrease the heat insulation effect. Also, be sure the condensation drain hose splits away from the bundle and drips clear of the unit and the tubing.

10.2.7 Finish 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. 34) shows refrigerant tubing taped separately from the drain hose.
