The above figures is an instance models, which would be
different from the one that you purchase.
The broken lines in above figures for illustrate the dimension
of air return box. (Lower side air return box and rear air return
box)
If you need to order air return box from us, please be specific
describe which kind you need.
7.3 Connect the accessional plastic water
tray (no air return box type without)

Two grooves
The accessional plastic water tray
Please hang up the accessional plastic water tray to the
pipes or ceiling by a rope.
8. PIPES CONNECTION
With air release valve, the other side is water inlet pipe.
When connect water collecter, set the tightening torque to
6180~7540N.cm(630~770kgf.cm), and use a spanner to
tighten it as shown in Figure.
The diameter of connective junction in water inlet pipe and
water outlet pipe is RC3/4 tapper pipe thread inside.
The diameter of condensate pipe is ZG3/4 tapper pipe thread
outside.

9. INSTALLATING DRAINAGE PIPE
Install the drain pipe of the fan coil unit
Before out from factory, the scupper adopts the pipe thread.
Be sure to perform heat insulation for the drain pipe of the
indoor unit. Otherwise, condensate will occur. The joint of the
indoor unit should also undergo heat insulation treatment.
When performing the pipes connection, use the rigid PVC
binder, and make sure that no leak exists.
Same as the joint of the indoor unit. Be careful not to apply
force at the pipe side of the indoor unit.
The downward gradient of the drain pipe should be higher
than (1/100), without bend in the middle.
The total length of the drain pipe when pulled out traversely
shall not exceed 20m, when the pipe is over long, a prop
stand must be installed prevent winging.
The centralized pipes should be distributed against the figure
shown on the right side.
Drain test
Before the test, ensure that the drain pipes are smooth and
the adapters are sealed.
Newly built rooms should undergo the drain test before the
ceiling is laid.
