NOTICE
1. To prevent distortion and breaking of the pipe, avoid applying sharp bends. Flex tube applying
a curve ratio of 6 inches (150 mm) or more.
2. Bending the tube repeatedly in the same place will cause the tube to break.
CAUTION
Make sure to connect the gas pipe after finishing the connection of the liquid pipe.
Indoor unit refrigerant piping
Tighten connecting pipe's flare nut at the valve coupling of the outdoor unit. Apply the same
tightening method as employed at the indoor unit.
Insulation of the piping connections
1. Refrigerant pipe must be insulated with the appropriate insulating material and plastic tape in
order to prevent condensation and water leaking.
2. Indoor unit connections must be wraped with insulating material. Do no leave any uncovered
gap on the indoor unit as shown in the image below.
4.
Do not bend piping when covered with insulation material. In this case, cut the insulation with a sharp
cutter as is shown below and then proceed to mold the naked pipe. Make sure that insulation is placed
back on the pipe and seal it using sealing tape.
