KPI-(502-1002)X4E
Make sure that the foundation is flat, taking into account the
maximum foundation gradient.
The unit should be installed so that one side of the unit is
slightly (approximately 1º (KPI-(502-1002)X4E) lower than the
other side, in order to avoid the incorrect position of the drain
discharge.
3.1.3 Connecting Field Supply Duct and Suction Air Filter Servicing

Field Supply Duct installation
The supply duct should be connected with the unit through
flexible duct, in order to avoid abnormal sounds and vibration.
The unit is equipped with a pre-drilled duct flange for the supply
duct connection.
1 Set the supplied rubber duct joint to each duct adapter to
ensure a good junction of the ducts.
2 Fit the ducts securely into the duct connecting flanges,
and wind aluminium tape available from hardware store to
prevent air leaks, also duct connection flanges have their
own sealing installed.
3 Suspend the ducts from the ceiling so that their weight will
not be applied to the unit.
4 The two outdoor ducts must be covered with heatinsulating
material in order to prevent condensation from forming.

eign matter (scraps of paper, vinyl, etc.) is inside the ducts.
Do not touch the damper plate inside the main unit when connecting
the ducts.
Do not install the ducts as shown in the next figures. Doing so, air
volume will be reduced and abnormal sounds may occur.
