SiMT041509E Safety Cautions
vi
Do not start or stop the air conditioner operation by plugging or
unplugging the power cable plug.
Plugging or unplugging the power cable plug 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
at a high place (more than 2 m).
Insufficient safety measures may cause a fall accident.
In case of R-32 / R-410A refrigerant models, be sure to use pipes, flare
nuts and tools for the exclusive use of 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 as well as an 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 refrigerating system, an excessively high pressure results,
causing equipment damage and injury.
Warning
Caution
Do not repair the electrical components with wet hands.
Working on the equipment with wet hands may cause an electrical shock.
Do not clean the air conditioner by splashing water.
Washing the unit with water may cause an electrical shock.
Be sure to provide the 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.
Be sure to conduct repair work with appropriate tools.
The use of inappropriate tools may cause injury.
Be sure to check that the refrigerating cycle section has cooled down
enough before conducting repair work.
Working on the unit when the refrigerating cycle section is hot may cause
burns.
