Notes:
a. Ensure piping and air duct working are most efficent length and units shall be installed in the
middle position of the room.
b. When installation of the indoor units, to ensure the distance shall be larger than 3m between
return air inlet and heat exchanger.
To install the refrigerant pipe drainage pipe. Specification for the refrigerant pipe and drainage
pipe, see the section
technical parameters of Usage Instruction. Use the torque spanner
to install the pipe to avoid damaging the copper tube and its joint.
Do not use the damaged copper tube or dirty copper tube. To avoid long time expose to the
air. Only get the concerned preparation ready, and do not open valves, connector, copper cap
and cushion before installation.
To install refrigerant pipe, all models of this series product should be connected with a E-EXV
box out of the machine, as shown in below figure.
Note: The E-EXV box contains electronic expansion valves, which needs to be mounted in
proper place on the liquid piping. When installing the E-EXV box, make sure the box vertical.
The E-EXV box and the indoor unit could not exceed the length-limit of the electric expansion
valve cable, as shown in the figure below.
There are some manners to install the E-EXV (the mounting must be fixed and safe, and the
direction must be vertical).
Wall or ceiling shall be strong enough to support indoor units. Otherwise, it may cause the unit
falling off.
Do not expose to sunshine.
Do not install units to the place where steam or oil smoke exists.
Do not install units to the place where burning gas leakage may happen.
Do not install around the high frequency equipment (such as high frequency electric welding
machine).
Do not install units in the place where acid liquid exists.
Do not install units in the place usually using sulfide or other sprayer.
