(11) There is adhesive on one side of the insulation so that after removing the protective paper over it
the insulation can be directly attached to the condensate hose.
(12) Considerations for the unit with the condensate pump:
1) For the unit with the condensate pump, only one drain port at the side close to the electric box
is prepared and only through it can the condensate hose can be connected.
2) See table 3 for the size of the drain port of the unit with the condensate pump, which is different
from that of the unit without the condensate pump.
3) For the unit with the condensate pump, two drain ports at the bottom are defaulted to be
factory plugged with drain caps. After the installation of the condensate hose, these two drain
ports also need to be insulated properly with the same way as aforementioned.
4) The condensate hose for the unit with the condensate pump should be arranged as shown
in the figure below.

The vertical height of the condensate hose should be 75mm (3inch) or less so that it is
unnecessary for the drain port to withstand additional force.

shown in the figure below.
