Step 11 Performing the drainage test
1
Do a leak test at the connection part of the flexible hose
and the drain pipe:
a
Connect a general hose to the connection part of
the flexible hose of the indoor unit, and pour in some
water.
Hose
Flexible hose
Water leakage
check part
b
After pouring some water, reassemble the rubber cap
on the connection part of a flexible hose of the indoor
unit and firmly tighten it with a band to prevent
leakage.
c
Check the leak test at the part where the adhesive for
the flexible hose and the drain pipe is used.
CAUTION
• The leak test must be performed for at least 24
hours.
2
Check the condensed water drainage:
a
Pour about 2 liters of water into the indoor unit drain
pan as shown in the picture.
b
When the electric cable connection is completed
• Turn on the indoor unit and outdoor unit.
• Operate in the Cool mode.
CAUTION
• Only in the Cool mode, you can check the correct
operation of the drain pump.
When the electric cable connection has not been
completed
• Remove the control box cover of the indoor unit.
• Connect the power supply to the L and N terminals.
• Reassemble the control box cover and turn on the
indoor unit.
CAUTION
• When the float switch is not detected due to
insufficient water on the drain pan, the drain
pump will not work.
• If the power supply is directly connected to the L
and N terminals, communication error message
might appear.
• After completing the drainage check, turn the unit
off and disconnect the power supply.
• Reassemble the control box cover.
c
Check whether the drain pump works correctly.
d
Check whether the drainage is performing
correctly at the end of the drain pipe.
e
Check for leakage at the drain pipe and drain pipe
connection part.
f
When leakage occurs, check whether the indoor
unit is level and check the drain hose connection
part, drainpipe connection part and drain pump
connection.
g
When the drainage check is completed and
the condensed water remains on the drain pan,
remove the water.
