INSTALLATION PRECAUTIONS


Safety precautions
Make sure to perform grounding
work.
Do not connect grounding wire to any
gas pipe, water pipe, conductor rods or
telephones. Incomplete grounding may
cause electric shock through leakage of
electricity.
Make sure to mount a leakage
breaker.
Otherwise electric shock may occur. Please
consult your dealer or a specialist for the
mounting.
Do not mount where flammable gas
leakage can happen.
If leaked gas stagnates in the unit, the gas
may cause fire.
Make sure to layout the drain pipe so
that the water is completely drained.
Otherwise, water may leak and wet
household goods.
OPERATION PRECAUTIONS
DANGER
Do not expose yourself directly to
radiator or any other heating device
for a long time.
It may cause low temperture burn injury.
Do not set water temperature too
high when under-floor heating
application is used.
It may cause low temperature burn injury.
Do not expose yourself directly to
cooled air flow for a long time or
cool too much.
It may be cause of deconditioning or
health disorder.
Do not insert fingers or sticks into
the air inlet or outlet grilles.
It may cause injuries because of the fan
rotating at high speed.
If the unit has been submerged under
water due to a natural disaster such as

pipe for dehumidification. Specialized
information and skills are required for
inspections and maintenances. Therefore
contact your dealer.
Do not place any object around the
outdoor unit, nor allow fallen leaves to
pile up.
Fallen leaves may induce insects and
worms in them, and they may lead to
failure, ignition or smoking by touching
electric components.
Do not use with inlet/outlet grilles or
other panel removed.
Otherwise, it may lead to injuries.
Do not operate or stop the unit by
using the power supply switch.

water.
Over 80 percent humidity or the clogging of
drain pipe may damage them through dew
dropping.
PRECAUTIONS FOR RELOCATION OR REPAIRING
CAUTION
Never perform any modification.
Contact your dealer for repairing.
Improper repairing may lead to water
leakage, electric shock or fire. Normally
the refrigerant does not leak. But if it leaks
and contacts fire such as fan heater, space
heater or cooking heater, it may produce
toxic chemicals. When repairing refrigerant
leakage, determine the service with the
service staff so that the repair has been
finished without fault.
If it is required to relocate and reinstall the
unit, consult your dealer or a specialist.
Improper installation of air conditioning unit
may cause water leakage, electric shock
and/or fire.
Before repairing or checking the
indoor unit, be sure to turn off “Indoor
unit power supply breaker”.
It can result in electric shock or injury due
to rotation of indoor unit fan if you perform
check or repair with the “Indoor unit power
supply breaker” turned on.
Place the panels removed for
repairing or checking on the stable
spot.
Otherwise, dropping or falling may lead to
injury.

CAUTION
An increase in the room temperature can be slowed by the
thermostatsfor the radiators or under floor heating.
Therefore, open the thermostats fully, except in those rooms
where a cooler temperature is required, e.g.bedrooms.
TIP
Wait 24 hours before making a new setting, so that the
roomtemperature has time to stabilise.
If it is cold outside temperature and the room temperature is
too low, increase the curve slope in menu1.9.1.1by one
increment.
If it is cold outside temperature and the room temperature is
too high,reduce the curve slope in menu1.9.1.1by one
increment.
If it is warm outside temperature and the roomtemperature
is too low, increase the value inmenu1.1.1by one increment.
If it is warm outside temperature and the roomtemperature
is too high,reduce the value in menu1.1.1by one increment.
