(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 drain 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 the drain 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 drain hose, these two drain ports also need
to be insulated properly with the same way aforementioned.
4) The drain hose for the unit with the condensate pump should be arranged as shown in the
figure below.

① The vertical height of the drain hose should be 75mm (3inch) or less so that it is unnecessary
for the drain port to withstand additional force.
