and then connect it to the drain port of the air conditioner body.
Tighten the both ends of the drain hose with hose band. In this time, be
sure to set the screw section of the hose band toward upper side.
• Apply thermal insulation the drain hose with the attached thermal
insulation pipe.
Set the both ends of the drain hose closely to the drain pan.
• If a gap is generated on the matched section of the thermal insulation
materials at the both ends, seal the section by winding the thermal
insulation tape.

. Drain piping
• Be sure to set the drain pipe from the drain up kit with falling gradient.
Support and fix the drain pipe at an appropriate position so that an
excessive load is not applied on the drain port.

Test run
Condition check of water drain
After the electric work and cabling work, check the drain is smoothly discharged
by running the air conditioner in COOL mode.
• If the cooling operation does not continue for a long time, pour water into the
drain pan of the air conditioner body to check whether the drain is smoothly
discharged or not.
• Check there is no water leak at each connecting section.
Operation check of float switch
• During cooling operation, operate the float switch.
Check the air conditioner stops the cooling operation under condition that the
drain pump keeps operating.
• After operation in COOL mode, operate the float switch.
In this time, check that the drain pump works to discharge the drain.
<Position of float switch>
• To handle the float switch, remove the
front panel of the kit and push up the
floating section of the float switch with a
screwdriver, etc.
• Be careful not to operate the float switch
consecutively for 2 minutes or more
because the air conditioner stops
abnormally.
