WARNING
▪
If the power supply has a missing or wrong N-phase, equipment might break
down.
▪
Establish proper earthing. Do NOT earth the unit to a utility pipe, surge absorber,
or telephone earth. Incomplete earthing may cause electrical shocks.
▪
Install the required fuses or circuit breakers.
▪
Secure the electrical wiring with cable ties so that the cables do NOT come in
contact with sharp edges or piping, particularly on the high-pressure side.
▪
Do NOT use taped wires, extension cords, or connections from a star system.
They can cause overheating, electrical shocks or fire.
▪
Do NOT install a phase advancing capacitor, because this unit is equipped with an
inverter. A phase advancing capacitor will reduce performance and may cause
accidents.
CAUTION
Do NOT push or place redundant cable length into the unit.
NOTICE
The distance between the high voltage and low voltage cables should be at least
50 mm.
NOTICE
Do NOT operate the unit until the refrigerant piping is complete. Running the unit
before the piping is ready will break the compressor.
NOTICE
If the power supply has a missing or wrong N-phase, equipment will break down.
NOTICE
Do NOT install a phase advancing capacitor, because this unit is equipped with an
inverter. A phase advancing capacitor will reduce performance and may cause
accidents.
NOTICE
NEVER remove a thermistor, sensor, etc., when connecting power wiring and
transmission wiring. (If operated without thermistor, sensor, etc., the compressor
may break down.)
