WARNING
ALWAYS use multicore cable for power supply cables.
WARNING
▪
All wiring MUST be performed by an authorised electrician and MUST comply
with the applicable legislation.
▪
Make electrical connections to the fixed wiring.
▪
All components procured on-site and all electrical construction MUST comply
with the applicable legislation.
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 shock.
▪
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, stranded conductor wires, extension cords, or
connections from a star system. They can cause overheating, electrical shock 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.
WARNING
Use an all-pole disconnection type breaker with at least 3 mm between the contact
point gaps that provide full disconnection under overvoltage category III.
WARNING
If the supply cord is damaged, it MUST be replaced by the manufacturer, its service
agent or similarly qualified persons in order to avoid a hazard.
WARNING
Do NOT connect the power supply to the indoor unit. This could result in electrical
shock or fire.
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.
