◆In order to start up the unit successfully, the main power switch should be opened 8 hours
before the operation.
◆After receiving the turn off signal, every indoor unit will continue to work for 20-70sec to
make good use of the rest cool air or the rest heat air in the heat exchanger, which will prepare for
the next operation. And this is normal.
◆ When the selected operating mode of the indoor unit is conicted to the operating mode of
the outdoor unit, 5 sec later, the malfunction hint will be shown on the indoor unit or wired controller,
then the indoor unit will stop. At this time, change the operating mode of the indoor unit to the one
that would not conict with the outdoor operating mode to make the operation normal. The HEAT

(1). Align the ared end of the copper tube with the threaded connector, and then hand-tighten
the ared nut.
(2). Further tighten the ared nut with a torque wrench until the torque wrench sounds a “crack”.
(3). The bending of the pipe shall not be too small, otherwise the pipe may crack. A pipe bender
must be used when bending the pipe.
(4). Wrap the thermally untreated pipe and connectors with sponge and then tighten the sponge
with plastic tape.
Notes:
① .
During the piping, do not pull any connector forcefully to prevent the capillary and other
pipes from cracking, which then would result in leakage.
② .
The pipe should be properly supported in the way that its weight will not be borne by the
unit.
If the specication of the outdoor unit pipe joint does not conform to that of the indoor unit, then
the joint specication of the outlet pipe of the indoor unit takes precedence. A reducing nipple shall
be installed at the joint of the outdoor unit so as to make the joint of the outdoor unit compatible
