ⅠUSER NOTICES
Thank you for your selection of TOYOTOMI air conditioners. Before installation and operation,
please read this manual carefully and keep it in handy place for future reference.
zDuring the operation, the entire capacity of the cooperating indoor unit should be not larger than
that of outdoor unit. Otherwise, it will cause the shortage of cooling (heating) capacity.
zA Breaker (or fuse) needs to be installed in every indoor unit, and the capacity should in according
with indoor unit’s electrical parameter; all the indoor units are required to be centralized
controlled by a total Switch, this Switch can cut off the electric power supply in case of emergency.
The breaker (or fuse) on each indoor units has the function of short circuit prevention and
avoiding abnormal overload, and it should be connected in normal situation. The main switch
should be capable of controlling the power supply of all the indoor units. Before clearing and
maintenance job being carried out to the indoor units, it is very important to turn off the total
power supply switch.
zIn order to turn on the units successfully, the main power switch should be opened 8 hours before
the operation.
zAfter receiving the turn off signal, every indoor unit will continue to work for 20-70sec to make
use of the rest cool air or the rest heat air in the heat exchanger, while preparing for the next
operation. And this is normal.
zWhen the selected operating mode of the indoor unit are clash with the operating mode of the
outdoor unit, the malfunction light will blink after 5s on the indoor unit or remote controller
showing that the operation clash, then the indoor unit will stop. At this time, change the operation
mode of the indoor unit to the one that would not clash with the outdoor operating mode to make
the operation normal. The cooling mode is not clash with the dry mode, while the fan mode is not
clash with any mode.
zThe appliance shall not be installed in the laundry
zAn all-pole disconnection switch having a contact separation of at least 3mm in all poles should
be connected in fixed wiring
zMissing information regarding electric supply tolerances (+/-10%, +/-1Hz) in documentation
zMissing information regarding humidity (30-95%) in documentation
zMissing information regarding installation altitude (max 1000m) in documentation
zInformation regarding transport/storage temperature (-25-55°C) is missing
zMain switch provided by end user: main switch handle should be black or gray, it can be locked in
“OFF” position with padlock
zThe main disconnection device should be explained in user manual and the height should be
recommended at 0.6-1.7m. Over current protection is required (EN 60947-3, EN 60947-2)
zThe cooling range of the unit is the outdoor environment temp.18-43 DB, the heating range of
the unit (only for the heat pump type unit) is the outdoor environment temp. -16-15 WB.

ⅡSAFETY INFORMATION
Please read this manual carefully before use this unit, and operate it correctly according to the guide
in this manual. Also, please take specially notices to the meaning of these two symbols：
Warning！This mark means that it may cause casualty or badly hurt if the operation is incorrect.
Note！This mark means that it may cause casualty or property loss if the operation is incorrect.
Warning！
zFor the usage safety of the air conditioner, the units should be earthed reliably, and the earth
wire should be connected to the special earth equipment in building. If there is no this kind
of equipment, have the units installed by specialized personnel. Do not connect the earth
line with the gas pipe, water pipe, drainage pipe or other places that specialized personnel
considers unsafe.
zAir conditioner must use special power supply circuit and switches for creepage protect and
air with enough capacity should be installed in the circuit.
zEnsure that the connecting of power cord is normal, otherwise, electric shock or fire may
happen.
zDo not cut off the power supply to turn off the unit when it is running, otherwise the useful
life of units may shortened.
zDo not mangle wire or adopts wires that are not recommend to use, otherwise, electric
shock or fire may happen.
zPlease don’t operate the unit by wet hand, or electric shock may happen.
zDon’t insert finger or stick like things into outlet vent, otherwise, damage may happen.
zCut down the main power switch immediately if malfunction (such as smell the burning
odor etc.) happen, and then contact the special engaged maintenance center. If the abnormal
state is maintained, the unit may be damaged or electric shock or fire may happen.
zDo not refit the conditioner. Please contact the agency or professional personnel to repair or
move the conditioner.
zDo not adopt fuse with unsuitable capacity or adopt iron thread instead of fuse, otherwise
malfunction or fire may happen.
zDo cut off the main power supply of air conditioner if it would not be used for a long time.
zPlease turn off the main power of the unit before cleaning the conditioner, otherwise electric
shock or harm may happen.
zDon’t blow the heater otherwise carbon monoxide may be produced for uncompleted
burning.
zChemical sprayer should be placed 1m or more away from the unit, otherwise fire or
explode may be caused.
zNo blockage is permitted in the inlet or outlet vent of the air conditioner, as this would
cause low efficacy or unit stop.
