4. Do not bend the pipe while it is encased in the insulation. In this case, cut the insulation with
a sharp cutter as shown below, and bend it after exposing the pipe. After bending is complete,
assure the insulation wrapping is sealed.
NOTICE
1. To prevent breaking of the pipe, avoid sharp bends. Bend the pipe with a radius of curvature
of 5.9 in. (150 mm) or more.
2. If the pipe is bent repeatedly at the same place, it will break.
CAUTION
Be sure to connect the gas pipe after connecting the liquid pipe completely.
Refrigerant Piping at the Outdoor Unit
Tighten the flare nut of the connection pipe at the outdoor unit valve connector. The tightening
method is the same as the method at the indoor unit.
Insulating the Pipe Joints
1. All refrigerant piping should be insulated with appropriate insulating material and
plastic tape in order to prevent condensation and water leakage.
2. The joints of the indoor unit should be wrapped with insulating material. No gap is
allowed on the joint of the indoor unit, as shown below.
