(5). Use a suitable drain hose, and see Table 3 for its size.
(6). There is a drain port on both the left and right sides. Select
the drain port to match the local conditions.(Fig.25)
(7). When the unit is shipped from the factory, the drain port is
defaulted to be the one on the left side (electric box side),
the port on right side has been plugged.
(8). When using the drain port on the right side of the unit,
reinstall the drain cap to the left side drain port.(Fig.27)
Fig.27
CAUTION!
Always check that the drain cap is installed to the unused drain port and is fastened with the nylon
fastener. If the drain cap is not installed, or is not sufficiently fastened by the nylon fastener, water may
drip during the cooling operation.
(9). Be sure to insulate where the drain port and the drain hose is connected.(Fig.28 )
(10). The unused drain port also should be insulated properly.(Fig.29)

(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:
i
). 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.
ii
). 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.
iii
). 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.
iv
). The drain hose for the unit with the condensate pump should be arranged as shown in the
figure below.
Fig.30
a. The vertical height of the drain hose should be 75mm or less so that it is unnecessary for
1000mm
