WARNING
▪ Do NOT use locally purchased electrical parts inside
the product.
▪ Do NOT branch the power supply for the drain pump,
etc. from the terminal block. This could result in
electrical shock or fire.
WARNING
Keep the interconnection wiring away from copper pipes
without thermal insulation as such pipes will be very hot.
DANGER: RISK OF ELECTROCUTION
All electrical parts (including thermistors) are powered by
the power supply. Do not touch them with bare hands.
DANGER: RISK OF ELECTROCUTION
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.
