Connecting the Humidifying Hose
1.
Connecting to indoor unit.
Keep the following items in mind in order to prevent the degrading of humidification performance when connecting the humidifying
hose to the indoor unit.
1) Cut the excessive portions of the humidifying hoses.
* Determine the overall length of the humidifying hoses according to the installation manual for the indoor unit.
2) Be sure to avoid traps as much as possible when installing the humidifying hoses.
3) Be careful not to crush the humidifying hoses in the case of bending the hoses at the time of
installation. Furthermore, make sure that the maximum bending radius will not exceed 90°.
4) Check that the overall length of the humidifying hoses is definitely 3m or more.
5) Attach a cover to the end of each humidifying hose so that no moisture or foreign substance
will go into the hose when leaving the hose without being connected to the outdoor and
indoor units.

• Make sure that the number of bending times will not exceed the
following limits at the time of installation.
3m-8m :3 times
8.1m-10m :4 times
10.1m-15m :5 times
• Use the KPMH996A15S (15m set) only if the overall length of
the humidifying hoses exceeds 10m.
Mark the cuff on the indoor unit side so
that the overall length of the hoses after
adjustment will be clearly known.
CAUTION
Connect the humidifying hose according to
the installation manual for the indoor unit.
Use the provided joint to connect the humidifying hoses.
Insert the joint into the humidifying hoses so that there
will be no clearance between the hoses on the joint,
and secure the position of 10mm from the end of each
hose with a binding band.

• Cut the 8m hose to adjust the overall length of the
humidifying hoses.
• Use the KPMH996A15S (15m set) only if the overall length of the
humidifying hoses exceeds 10m.
1) Be sure to connect one of the 2m hoses (provided with a cuff each) to
the indoor unit and the other one to the outdoor unit.
Connect the 7.5m hose and 3.5m hose midway to adjust the overall
length.

with a cuff each) and the 7.5m
hose all together through the
reducing joint if the overall length of
the humidifying hoses is 11.5m or
less.
• Cut the 7.5m hose to adjust the
overall length of the humidifying
hoses.
