CAUTION
Refer to the figures for correct installation
procedure.
Ensure that the condensate drain pipe and its
connections are properly insulated to prevent
condensation and water leaks.
Connect the pipe with appropriate adhesive
to ensure a proper fit with no leaks.
Do not put undue stress on the condensate fittings,
it may cause the pipe to break and leak.
The downward slope of the condensate drain pipe
should be at least 1:50, do not bend or let droop.
Condensate drain pipe length shall be less than
20m. Install pipe supports as required to prevent
the pipe from drooping and trapping condensate.
Slope downward at least 1:50

As deep as possible (at least 10cm)
Installation accessories
Duct design - Low Static (40 - 70Pa)
This is a low static unit, ensure that the duct is
as short as possible to minimise static pressure.
Duct installation
Fix the ducts onto the spigots.
NOTE:
1.Do not let the indoor unit bear the weight of duct.
2.Allow adequate space for service and
maintenance.
3.In noise critical spaces like meeting rooms or
bedrooms, use acoustic duct and/or additional
insulation to minimise noise.
Acoustic duct and insulation are field supplied
Use a flexible duct connection on the supply and
return air spigots to isolated any vibration.
Support the ducts independently of the unit.
