Precautions
WARNING
Attachment
Installation must be performed by qualified professionals.
Otherwise, it may cause personal injury or damage.
Must follow the electric safety regulations when installing
the unit.
According to the local safety regulations, use qualified
power supply circuit and circuit break.
Do install the circuit break. If not, it may cause malfunction.
An all-pole disconnection switch having a contact separation
of at least 3mm in all poles should be connected in fixed
wiring.
Including an circuit break with suitable capacity, please
note the following table. Air switch should be included
magnet buckle and heating buckle function, it can protect
the circuit-short and overload.
