or for commercial use by lay persons.
1. SAFETY PRECAUTIONS
&.
WARNING
• Installation and maintenance should be performed
by qualified persons who are familiar with local code
and regulation, and experienced with this type of
appliance.
• All field wiring must be installed in accordance with
the national wiring regulation.
• Ensure that the rated voltage of the unit corresponds
to that of the name plate before commencing wiring
work according to the wiring diagram.
• The unit must be GROUNDED to prevent possible
hazard due to insulation failure.
• Be sure to install an earth leakage breaker.
Failure to install an earth leakage breaker may
result in electric shocks or fire.
• All electrical wiring must not touch the refrigerant
piping, or any moving parts of the fan motors.
• Confirm that the unit has been switched OFF before
installing or servicing the unit.
• Disconnect from the main power supply before
servicing the air conditioner unit.
• DO NOT pull out the power cord when the power is
ON. This may cause serious electrical shocks which
may result in fire hazards.
• Keep the indoor and outdoor units, power cable
and transmission wiring, at least 1 m from TVs and
radios, to prevent distorted pictures and static.
(Depending on the type and source of the electrical
waves, static may be heard even when more than
1m away).
Special notice of product
[REFRIGERANT]
The system uses R41 OA refrigerant.
The refrigerant R41 OA requires that strict precautions
be observed for keeping the system clean, dry and
tightly sealed. The following procedures must be
followed correctly,
A. Clean and dry
Strict measures must be taken to keep impurities
(including SUNISO oil and other mineral oils as well
as moisture) out of the system.
B. Tight sealed
Take care to keep the system tight when installing.
R41 OA contains no chlorine, does not destroy the
ozone layer and so does not reduce the earth's
protection against harmful ultraviolet radiations.
R41 OA will contribute only slightly to the
greenhouse effect if released to the atmosphere.
&.CAUTION
Please take note of the following important points
when installing.
• Do not install the unit where leakage of
flammable gas may occur.
t<::""\
If gas leaks and accumulates around the unit,
\.Y it may cause fire ignition.
• Ensure that drainage piping is connected
properly.
If the drainage piping is not connected
0
properly, it may cause water leakage which
will dampen the furniture.
• Do not overcharge the unit.
t<::""\
Overcharge will cause over-current or damage
\.Y to the compressor.
• Ensure that the unit's panel is closed after
service or installation.
0
Unsecured panels will cause the unit to
operate noisily.
• Sharp edges and coil surfaces are potential
locations which may cause injury hazards.
Avoid from being in contact with these places.
• Before turning off the power supply, set the
remote controller's ON/OFF switch to the "OFF"
position to prevent the nuisance tripping of the
unit. If this is not done, the unit's fans will start
turning automatically when power resumes, posing
a hazard to service personnel or the user.
• Do not install the units at or near doorway.
• Do not operate any heating apparatus too close
to the air conditioner unit or use in room where
mineral oil, oil vapour or oil steam exist, this
may cause plastic part to melt or deform as a
result of excessive heat or chemical reaction.
• When the unit is used in kitchen, keep flour away
from going into suction of the unit.
• This unit is not suitable for factory used where
cutting oil mist or iron powder exist or voltage
fluctuates greatly.
• Do not install the units at area like hot spring
or oil refinery plant where sulphide gas exists.
• Ensure the color of wires of the outdoor unit and
the terminal markings are same to the indoors
respectively.
• IMPORTANT: DO NOT INSTALL OR USE THE
AIR CONDITIONER UNIT IN A LAUNDRY ROOM.
• Don't use joined and twisted wires for incoming
power supply.
NOTE:
[DESIGN PRESSURE]
The design pressure of the system in 4.17MPa. Since R41 OA is a mixed refrigerant, the required additional refrigerant
must be charged in its liquid state (if the system is charged with refrigerant in its gaseous state, the system will not
function normally
due to the composition change
).
