SiUS071735EB Safety Cautions
vi
Be sure to discharge the capacitor completely before conducting repair
work.
The step-up capacitor supplies high-voltage electricity to the electrical
components of the outdoor unit.
A charged capacitor may cause an electrical shock.
Do not turn the air conditioner on or off by plugging in or unplugging the
power cable.
Plugging in or unplugging the power cable to operate the equipment may cause
an electrical shock or fire.
Be sure to wear a safety helmet, gloves, and a safety belt when working
in a high place (more than 2 m (6.5 ft)).
Insufficient safety measures may cause a fall.
In case of R-32 / R-410A refrigerant models, be sure to use pipes, flare
nuts and tools intended for the exclusive use with the R-32 / R-410A
refrigerant.
The use of materials for R-22 refrigerant models may cause a serious accident,
such as a damage of refrigerant cycle or equipment failure.
Do not mix air or gas other than the specified refrigerant (R-32 / R-410A /
R-22) in the refrigerant system.
If air enters the refrigerant system, an excessively high pressure results,
causing equipment damage and injury.
Warning
Caution
Do not repair electrical components with wet hands.
Working on the equipment with wet hands may cause an electrical shock.
Do not clean the air conditioner with water.
Washing the unit with water may cause an electrical shock.
Be sure to provide an earth / grounding when repairing the equipment in
a humid or wet place, to avoid electrical shocks.
Be sure to turn off the power switch and unplug the power cable when
cleaning the equipment.
The internal fan rotates at a high speed, and may cause injury.
