MCAC-KTSM-2012-03 High static pressure ducted
FCU
Installation 27
Steel beam and grider structure: Set and use supportive angle steel.
Suspending the indoor unit
Use tools such as pulleys to hoist the indoor unit to the pendant bolt.
Use tools such as gradient to settle the indoor unit horizontally. Lack of horizontality may cause
water leak.
Connect the duct
The external static pressure is 70Pa or 100Pa, and the duct length is determined according to this
parameter.
Install the wire control switch
For installation of the wire control switch, see the installation manual of the wire controller.
Sample unit specification figure: refer to chapter 7
12.2 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 Fig..
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.
12.3 Installing Drainage Pipe
Cautions:
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 en suite connection, use the rigid PVC binder, and make sure that no leak exists.
