8. PIPES CONNECTION
With air release valve, the other side is water inlet pipe.
When connect water collector, 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.
Bend
S-shape

The diameter of condensate pipe is ZG3/4 tapper pipe thread
outside.

As large as practicable (approx. 10cm)
Downward gradient
is over 1/100

9. INSTALLATING DRAINAGE PIPE
Install the drainpipe of the fan coil unit
Before out from factory, the scupper adopts the pipe thread.
Before the test, ensure that the drainpipes are smooth and
the adapters are sealed.
Newly built rooms should undergo the drain test before the
ceiling is laid.
NOTE
Be sure to perform heat insulation for the drainpipe 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 drainp i p e should be higher
than (1/100), without bend in the middle.
The total length of the drainpipe when pulled out traverse 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.
