INSTALLATION PRECAUTIONS
DANGER
Make sure to have the installation
done by your dealer or a specialist.
If you install by yourself and the unit is not
properly installed, water leakage, electric
shock, fire and injuries caused by the drop
of the unit may occur.
The preventive measures that the
density of leaked refrigerant does not
exceed the limit is necessary in case of
installing the unit in a small room.
The leakage of refrigerant may cause oxygen
deficiency accident. Consult your dealer for
the measures.
RC-HY20/40 must be installed via an isolator
switch with a minimum breaking gap of 3
mm.
If the supply cable is damaged, only MHI, its
service representative or similar authorised
person may replace it to prevent any danger
and damage.
CAUTION
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
flood or typhoon, consult your dealer
before using it again.
If you use it as it stands, it may lead to
failure, electric shock or fire.
If any abnormal symptom (scorched
flavor etc.) is found, cut off the power
and stop the operation.
Then consult your dealer.
If you use it as it stands, it may lead to
failure, electric shock or fire.
One of the causes of poor cooling
or poor heating may be refrigerant
leakage. Please consult your dealer.
If the repair requires additional refrigerant,
determine the service with the service
staff. The refrigerant of air conditioner is
not toxic. 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.

4
Safety precautions
Do not insert fingers or sticks even if
air blower does not operate.
It may suddenly operate and cause injuries.
CAUTION
Do not use for particular purpose such
as the storage of food, animals and
plants, precision apparatus and arts etc.
Storage goods may degrade.
Do not operate the button with wet
hand.
It may cause electric shock.
When a burning appliance is used
together with the unit, ventilate frequently.
If ventilation is not sufficient, it may cause
oxygen deficiency accident.
Do not place a burning appliance where
the airflow from the unit is directly
blown in case fan coil is used.
It may cause the imperfect combustion of
the equipment.
Make sure that the unit installation
foundation is not damaged due to long-
term use.
If it is left to stand, the unit may fall down
causing injury.
Do not lean on the unit.
It may overturn or fall if it is placed on
unstable surface and if may cause injury.
Do not wash the unit with water, nor
place a vase with water on the unit.
It may cause a electric shock or ignite.
Do not install the unit where the airflow is
directly blown towards animals and plants.
They may suffer from adverse effect.
Before cleaning, make sure to stop
operation and cut off the power.
The fan inside rotates at high speeds.
Make sure to use an appropriate fuse.
Using steel wire or copper wire may
lead to failure or fire.
Do not store a flammable spray etc. near
the unit, nor blow directly to the unit.
It may lead to fire.
Before maintenance, make sure to
stop operation and cut off the power.
The fan inside rotates at high speeds.
When the unit isn’t used for a whole,
cut off the power.
The accumulation of dirt may lead to heat
generation or fire. But, before resuming
the operation, turn on the unit for six hours
beforehand to ensure safe operation.
Do not place any other electric appliances
or household goods below or around the
air conditioner.
Lekage from the unit may lead to failure or
contamination.
Do not touch the aluminum fin.
Otherwise it may lead to injuries.
Do not clean the inside of the indoor unit
by yourself. Make sure to consult your
dealer or user inquiry counter specified by
our company.
If you select incorrect detergent or
improper method, resin parts may be
damaged and lead to water leakage. If
the detergent is dropped on the electric
component or motor, it may lead to failure,
smoking or ignition.
Do not place objects on the outdoor unit,
nor mount on it.
It may lead to injuries resulting from falling.
During the operation or maintenance,
do not use an unstable footrest.
It may lead to injuries resulting from falling.
During thunderstorm, stop the
operation and turn off the switch.
A lightning strike may lead to failure.
After several seasons of operating,
inspections and maintenances are
required except routine care and cleaning.
Accumulated dirt or dust inside the indoor
unit may cause odor, water leakage
through the clogging of water discharging
pipe for dehumidification. Specialized
information and skills are required for
inspections and maintenances. Therefore
contact your dealer.

5
Safety precautions
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.
It may lead to fire or water leakage.
If auto restart is set effectively, the fan
may rotate suddenly causing injuries.
Do not strain the remote control cord.
A part of core wire may be cut off
causing electric leakage.
Do not use water heater etc. near the
indoor unit or remote control.
If a Vapor-generating appliance is used
near them, it may lead to water drop
causing electric leakage or short circuit.
Do not use the unit where powder or
fiber is floating.
Fine powder or fiber passing through the
air filter may stagnate inside the unit and
lead to electric leak or short circuit.
Do not place objects under the unit
which must avoid being exposed to
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.
