VRV IV system air conditioner
4P388987-1C – 2016.02
Corner units
Ceiling suspended units
Wall-mounted units
For the following conditions, a micro computer controls the air flow
direction which may be different from the display.
Cooling Heating
▪ When the room temperature is
lower than the set
temperature.
▪ When starting operation.
▪ When the room temperature is
higher than the set
temperature.
▪ At defrost operation.
▪ When operating continuously at horizontal air flow direction.
▪ When continuous operation with downward air flow is performed
at the time of cooling with a ceiling-suspended or a wall-mounted
unit, the micro computer may control the flow direction, and then
the user interface indication will also change.
The air flow direction can be adjusted in one of the following ways:
▪ The air flow flap itself adjusts its position.
▪ The air flow direction can be fixed by the user.
▪ Automatic
and desired position .
WARNING
Never touch the air outlet or the horizontal blades while the
swing flap is in operation. Fingers may become caught or
the unit may break down.
NOTICE
▪ The movable limit of the flap is changeable. Contact
your dealer for details. (only for double-flow, multi-flow,
corner, ceiling-suspended and wall-mounted).
▪ Avoid operating in the horizontal direction
. It may
cause dew or dust to settle on the ceiling or flap.

b VRV direct expansion (DX) indoor unit
c User interface (dedicated depending on indoor unit type)
d User interface (wireless, dedicated depending on indoor
unit type)
When the system is installed as shown in the figure above, it is
necessary to designate one of the user interfaces as the master user
interface.
The displays of slave user interfaces show
(change-over
under centralised control) and slave user interfaces automatically
follow the operation mode directed by the master user interface.
Only the master user interface can select heating or cooling mode.
13 Maintenance and service
NOTICE
Never inspect or service the unit by yourself. Ask a
qualified service person to perform this work.
WARNING
Never replace a fuse with a fuse of a wrong ampere ratings
or other wires when a fuse blows out. Use of wire or
copper wire may cause the unit to break down or cause a
fire.
CAUTION
Do not insert fingers, rods or other objects into the air inlet
or outlet. Do not remove the fan guard. When the fan is
rotating at high speed, it will cause injury.
CAUTION
After a long use, check the unit stand and fitting for
damage. If damaged, the unit may fall and result in injury.
NOTICE
Do not wipe the controller operation panel with benzine,
thinner, chemical dust cloth, etc. The panel may get
discoloured or the coating peeled off. If it is heavily dirty,
soak a cloth in water-diluted neutral detergent, squeeze it
well and wipe the panel clean. Wipe it with another dry
cloth.
13.1 About the refrigerant
This product contains fluorinated greenhouse gases. Do NOT vent
gases into the atmosphere.
Refrigerant type: R410A
Global warming potential (GWP) value: 2087.5
NOTICE
In Europe, the greenhouse gas emissions of the total
refrigerant charge in the system (expressed as tonnes
CO
2
-equivalent) is used to determine the maintenance
intervals. Follow the applicable legislation.
Formula to calculate the greenhouse gas emissions:
GWP value of the refrigerant × Total refrigerant charge [in
kg] / 1000
Please contact your installer for more information.
WARNING
The refrigerant in the air conditioner is safe and normally
does not leak. If the refrigerant leaks in the room, contact
with a fire of a burner, a heater or a cooker may result in a
harmful gas.
Turn off any combustible heating devices, ventilate the
room and contact the dealer where you purchased the unit.
Do not use the air conditioner until a service person
confirms that the portion where the refrigerant leaks is
repaired.
13.2 After-sales service and warranty
13.2.1 Warranty period
▪ This product includes a warranty card that was filled in by the
dealer at the time of installation. The completed card has to be
checked by the customer and stored carefully.
