Installation Instructions
Piping Joints Thermal Insulation:
Wrap the piping joints with thermal
insulation materials and then wrap
with a vinyl tape.
Piping Thermal Insulation:
a. Place the drain hose under the piping.
b. Insulation material uses polythene foam over
in thickness.
Note: Drain hose is prepared by user.
3/8"
Drain pipe should point downward for easy drain flow.
Do not arrange the drain pipe twisted, sticking out or wave
around, do not immerse the end of it in water.
If an extension drain hose is connected to the drain pipe, make
sure to thermal insulated when passing along the indoor unit.
When the piping is directed to the right, piping, power
Cord and drain pipe should be thermal insulated and
fixed onto the back of the unit with a piping
. connector

Tighten flares to below torques:
Connecting the refrigerant lines between the indoor& outdoor units
Note that since the refrigerant metering device is located in the outdoor unit,both refrigerant
lines must be insulated with a minimum of 3/8
foam along the entire length.
Gently bend the line set stubs from the indoor unit to the desired location and the using 2 box
end or adjustable wrenches,remove the flare nuts from the indoor unit line stubs.The indoor
unit is charged with a dry gas.If you do not hear the release of pressure when removing the
flare nuts,it is possible that the evaporator section(indoor unit)has developed a leak and you
should contact your dealer for a replacement indoor unit.Note:Using a small amount of
vacuum pump oil on the male flare threads will ease installation.Snug the line set to the stubs
using the 2 wrenches-one wrench on the male fitting and one wrench on the female fitting.
