WARNING
▪
In order to prevent oxygen deficiency and R32 combustion, keep the room well-
ventilated for a healthy work environment. Do NOT work in a confined space. If a
refrigerant leak is detected in a confined room or an inadequately ventilated
location, do NOT start the work until the area has been ventilated appropriately.
▪
If the work area is NOT located in the open air, make sure the work area is
adequately ventilated before breaking into the system or conducting any brazing.
The ventilation MUST continue to operate during the period that the work is
carried out to prevent accumulation of refrigerant in the work area. The
ventilation should safely disperse any released refrigerant and preferably
ventilate to the open air.
WARNING
Ensure that no external live wiring is exposed while charging, recovering or purging
the system. Sparks created when live wiring is short-circuited might ignite the
refrigerant if it is leaked into the room while charging, recovering or purging the
system.
WARNING
Ensure that the unit is properly earthed prior to conducting maintenance or service
or charging the system with refrigerant. Do NOT earth the unit to a utility pipe, surge
absorber, or telephone earth. Incomplete earthing may cause electrical shock.
WARNING
▪
ONLY use copper wires.
▪
Make sure the field wiring complies with the applicable legislation.
▪
All field wiring MUST be performed in accordance with the wiring diagram
supplied with the product.
▪
NEVER squeeze bundled cables and make sure they do NOT come in contact with
the piping and sharp edges. Make sure no external pressure is applied to the
terminal connections.
▪
Make sure to install earth wiring. Do NOT earth the unit to a utility pipe, surge
absorber, or telephone earth. Incomplete earth may cause electrical shock.
▪
Make sure to use a dedicated power circuit. NEVER use a power supply shared by
another appliance.
▪
Make sure to install the required fuses or circuit breakers.
▪
Make sure to install an earth leakage protector. Failure to do so may cause
electrical shock or fire.
▪
When installing the earth leakage protector, make sure it is compatible with the
inverter (resistant to high frequency electric noise) to avoid unnecessary opening
of the earth leakage protector.
WARNING
Make sure the markings on the unit remain visible and legible after inspection or
repair work. Markings and signs that are illegible shall be corrected.
WARNING
▪
After finishing the electrical work, confirm that each electrical component and
terminal inside the electrical components box is connected securely.
▪
Make sure all covers are closed before starting up the unit.
