1.2 Dangers
DANGER: RISK OF BURNING/SCALDING
▪
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.
DANGER: RISK OF ELECTROCUTION
▪
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 10 minutes, 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, see the wiring diagram. If the
measured voltage is still higher than 50 V DC, discharge the capacitors in a safe
manner by using a dedicated capacitor discharge pen to avoid possibility of
sparking.
▪
Do NOT touch electrical components with wet hands.
▪
Do NOT leave the unit unattended when the service cover is removed.
▪
Protect electric componennts from getting wet while the service cover is opened.
