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

DANGER
Before obtaining access to terminal devices, all supply
circuits must be interrupted.
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.
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.)
Installation manual
8
Charge the liquid
refrigerant with the
cylinder in up-side-down
position.
Equipment complying with EN/IEC 61000-3-12
WARNING
All components procured on the site and all electric
construction shall comply with the applicable local and
national regulations.
Use only copper wires.
Never squeeze bundled cables into a unit.
Fix cables so that cables do not make contact with the
pipes (especially on high pressure side).
Secure the electrical wiring with cable ties as shown
in the figure below so that it does not come in contact
with the piping, particularly on the high-pressure side.
Make sure no external pressure is applied to the
terminal connectors.
Be sure to install the required fuses.
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 9),
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.
Failure to do so may cause electrical shock.
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.
DANGER
Do not turn ON the safety breaker until all work is
completed.

currents produced by equipment connected to public low-voltage systems
with input current >16 A and ≤75 A per phase.
