The filled out label must be adhered on the inside of the product and
in the proximity of the product charging port (e.g. on the inside of the
service cover).
Precaution for servicing
This unit requires additional charging of refrigerant according to the
length of piping connected at the site. Charge the refrigerant to the
liquid pipe in its liquid state. Since R410A is a mixed refrigerant, its
composition changes if charged in a state of gas and normal system
operation would no longer be assured.
On this model it is not necessary to charge additionaly if the piping
length ≤7.5 m.
Additional charging of refrigerant
■ Over 7.5 m, please add refrigerant quantity according to the
following table.
For future servicing, mark with a circle the selected amount on the
table below.
Additional charging amount <unit: kg>
Total charging weight of the refrigerant (after a leak,
etc.)
When the entire refrigerant pipe length is within 7.5 meters, charge
the refrigerant in accordance with the amount mentioned in the
nameplate, and when the pipe length exceeds 7.5 meters, the
charging amount mentioned in the nameplate and that required for
additional charging are to be totalled as the net charging amount.
Precaution for pumping-down operation
The outdoor unit is equipped with a low-pressure switch to protect the
compressor.
Take the following steps to perform the pumping-down operation.
This is the end of pumping-down operation. After pumping-down
operation, the remote controller can show the following:
- "U4"
-blank screen
- indoor fan operates for about 30 seconds
Even when the ON button on the remote controller is pressed, it will
not operate. Turn off the main power supply switch and turn it on
again in need of operation.
ELECTRICAL WIRING WORK
NOTE
National implementation of EU regulation on certain
fluorinated greenhouse gases may require to provide the
appropriate official national language on the unit.
Therefore, an additional multilingual fluorinated
greenhouse gases label is supplied with the unit.
Sticking instructions are illustrated on the backside of that
label.
When performing service on the unit requiring the
refrigerant system to be opened, refrigerant must be
evacuated according to local regulations.
NOTE
Piping length is the 1 way length, gas or liquid.
Connected piping length is between
Class
7.5~30 m 30~40 m 40~50 m
71 +0.20 +0.70 +1.20
100+125 +0.10 +0.60 +1.10
NOTE
In case of complete recharge of the refrigerant, please first
execute vacuuming. Execute this vacuuming from the
service port. Do not use the port of the stop valve for
vacuuming. Vacuuming can not be executed completely
using such port.
Position of service port:
Heat pump units have 2 ports on the piping. One
between the liquid receiver and the electronic
expansion valve and another one between the heat
exchanger and the 4-way valve.

NOTE
Never short-circuit the low pressure switch in this
operation.
Procedure Precaution
1 Put a pressure gauge at the
service port of the gas stop valve.
Use a pressure gauge reserved for
R410A exclusively.
2 Start the fan operation with the
remote controller.
Confirm that stop valves both on
the liquid and gas side are open.
3 Push the pumping-down button on
the PC board of the outdoor unit.
Compressor and outdoor fan will
start operation automatically.
If step 3 is performed before step
2, then the indoor fan may
automatically start running. Please
pay attention to this.
4 Continue operation for 2 minutes
until operation condition stabilizes.
—
5 Close the stop valve on the liquid
side securely. (See "How to use
the shut-off valve" on page 6)
Insecure closing of the valve may
result in burning of the
compressor.
6 When the low-pressure switch is
activated, the unit stops working.
At this time, close the stop valve on
the gas side.
—
■ All wiring must be performed by an authorized
electrician.
■ All components procured on the site and all electric
construction should comply with the applicable local
and national codes.
■ High voltage
To avoid electrical shock, make sure to disconnect the
power supply 1 minute or more before servicing the
electrical parts. Even after 1 minute, always measure
the voltage at the terminals of main circuit capacitors
or electrical parts and, before touching, make sure
that those voltages are 50 V DC or less.
NOTE
To persons in charge of electrical wiring work:
Do not operate the unit until the refrigerant piping is
complete. (Running it before the piping is ready will break
the compressor.)
