3. Installation of drainage pipe
According to spot requirement, drainage pipe
is provided by the user and connected firmly
with drainage pipe equipped on the machine
(pay attention to the joint to prevent from
water leakage). Indoor part of drainage pipe
should be made heatproof with heat insulation
materials to prevent from condensation.

Note: Outlet direction of drainage pipe is as
the right diagram.

Air tightness test
Evacuation Addition of refrigerant
Air tightness test, evacuation and addition of refrigerant should be carried on according to installation
manual of outdoor unit.
During air tightness test, indoor unit cannot be powered on until vacuum evacuation is finished.
(Internal electronic expansion valves will all close and evacuation cannot be fully done just from
either fluid or gas side of distribution tube if indoor unit is powered on). Otherwise, evacuation
should be done from both sides of the distribution tube.
Note
Air leakage test
Check air leakage from joint part of distribution tube and valve covers of outdoor unit.
Checkup of joint part of distribution tube MUST adopt the same refrigerant as inside the machine.
(NOTE:To type AC092-282FEAHA units used refrigerant R22.
To type AC092-282FEBHA units used refrigerant R407C .)
Open all valves of outdoor unit
Heat insulation
Use attached heatproof pipe for heat insulation of joint part of distribution tube of indoor unit and
make it seamless.
Poor heat insulation can cause moisture condensation and result in water leakage
