W : R
ARNING
• Do NOT touch the refrigerant piping, water piping or internal parts during and immediately after operation. It could
be too hot or too cold. Give it time to return to normal temperature. If you must touch it, wear protective gloves.
• Do NOT touch any accidental leaking refrigerant.
W
ARNING
Always recover the refrigerants. Do NOT release them directly into the environment. Use a recovery pump to evacuate
the installation.
Take sufficient precautions in case of refrigerant leakage. If refrigerant gas leaks, ventilate the area immediately.
Possible risks:
• Excessive refrigerant concentrations in a closed room can lead to oxygen deficiency.
• Toxic gas may be produced if refrigerant gas comes into contact with fire.
Where applicable, pump down the system and close the service valve, before leaving the site if leak was not repaired,
to avoid further leaking of the refrigerant.
W : R
ARNING
• Turn OFF all power supply before removing the switch box cover, connecting electrical wiring or touching electrical
parts. Where applicable, stop the equipment's operation first and allow (refrigerant) pressure to equalize, before
turning OFF the power. Disconnect the power supply for more than 1 minute, and measure the voltage at the
terminals of main circuit capacitors or electrical components before servicing. The voltage must be less than 50 V
DC before you can touch electrical components. For the location of the terminals, refer to
page 144.
• Do NOT touch electrical components with wet hands.
• Do NOT leave the unit unattended when the service cover is removed.
• Protect electric components from getting wet while the service cover is opened.
W
ARNING
• Only use copper wires.
• All field wiring must be performed in accordance with the wiring diagram and installation manual supplied with the
product.
• If the power cable and lead wires have scratches or deteriorated, be sure to replace them. Damaged cable and wires
may cause an electrical shock, excessive heat generation or fire.
• Secure all terminal connections and provide proper routing for cables, both inside and outside the switchbox.
• 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 check the earth wiring. Do NOT earth the unit to a utility pipe, surge absorber, or telephone earth.
Improper earth wiring may cause electrical shock.
• Make sure to use a dedicated power circuit. NEVER use a power supply shared by another appliance.
• Make sure to check the required fuses and/or circuit breakers before starting works.
W
ARNING
• 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 the unit again.
