Charging refrigerant

This outdoor unit is factory charged.
Important information regarding the refrigerant used
This product contains fluorinated greenhouse gases covered by the
Kyoto Protocol. Do not vent gases into the atmosphere.
Refrigerant type: R410A
(1)
GWP value: 1975
(1)
GWP = global warming potential
Please fill in with indelible ink,
the factory refrigerant charge of the product,
the additional refrigerant amount charged in the field and
+ the total refrigerant charge
on the fluorinated greenhouse gases label supplied with the product.
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).

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
greenhouse gases label is supplied with the unit.
Sticking instructions are illustrated on the backside of
that label.
Re-charging
In case re-charging is required, refer to the nameplate of the unit. The
nameplate states the type of refrigerant and necessary amount.

Charging additional refrigerant
If the total length of refrigerant piping exceeds 10 m in length,
additionally charge with 20 g of refrigerant (R410A) for each
additional meter of piping.
Determine the weight of refrigerant to be charged additionally and fill
in the amount in the service sticker on the rear side of the stop valve
cover.

Precautions when adding R410A

Be sure to charge the specified amount of refrigerant in liquid
state to the liquid pipe.
Since this refrigerant is a mixed refrigerant, adding it in gas form
may cause the refrigerant composition to change, preventing
normal operation.
Before charging, check whether the refrigerant cylinder is
equipped with a siphon tube or not (the cylinder should be
marked with "liquid filling siphon attached" or something similar).
Charge the liquid
refrigerant with the
cylinder in upright
position.
Be sure to use tools exclusively for R410A to ensure required
pressure resistance and to prevent foreign materials from mixing
into the system.

Wiring

WARNING
All wiring must be performed by an authorized
electrician.
The power supply cable and circuit breaker must be
selected in accordance with local and national
regulations.
Do not use tapped wires, stranded conductor wires
(see caution 1 under "Notes to observe" on page 7),
extension cords, or connections from a star system,
as they may cause overheating, electrical shock or
fire.
Do not use locally purchased electrical parts inside
the product and do not branch the power for the
heater tape, etc., from the terminal block. Doing this
may cause electrical shock or fire.
Be sure to install an earth leakage circuit breaker.
This unit uses an inverter, which means that an earth
leakage circuit breaker capable of handling high
harmonics needs to be used in order to prevent
malfunctioning of the earth leakage circuit breaker
itself.
A main switch or other means for disconnection,
having a contact separation in all poles, must be
incorporated in the fixed wiring in accordance with
relevant local and national legislation.
WARNING
Do not turn ON the safety breaker until all work is
completed.
Equipment complying with EN/IEC 61000-3-12
(1) European/International Technical Standard setting the limits for harmonic
currents produced by equipment connected to public low-voltage systems
with input current >16 A and ≤75 A per phase.
Charge the liquid
refrigerant with the
cylinder in up-side-down
position.
