INSTALLING THE
INDOOR UNIT
Installing and Connecting the Indoor Unit Drain Hose
To install the drain hose, proceed as follows.
1 If necessary, connect the 6.7ft(2m) extension to the drain hose.
2 If you are using the extension, insulate the inside part of the extension drain hose with a
shield.
3 Pass the drain hose under the refrigerant piping, taking care to keep the drain hose tight.
4 Pass the drain hose through the hole in the wall, making sure that it is sloping downwards,
as shown in the illustrations above.
➢ The hose will be fixed permanently into position once the
whole installation has been tested for gas leaks; refer to
page 19 for further details.
Care must be taken when installing the drain hose for the indoor unit to ensure that any condensation water
is correctly drained outside. When passing the drain hose through the inch(65mm) hole drilled in the wall,
check that none of the following situations occur.
The hose must
NOT slope
upwards.
The end of the drain
hose must NOT be
placed in water.
Do NOT bend the
hose in different
directions.
Keep a clearance of at
least 2inch(50mm)
between the end of the
hose and the ground.
Do NOT place the
end of the drain hose
in a hollow.
