1.1.2 Cautions Regarding Products after Repair
Caution
Do not repair the electrical components with wet hands.
Working on the equipment with wet hands can cause an electrical shock.
Do not clean the heat pump by splashing water.
Washing the unit with water can cause an electrical shock.
Be sure to provide the 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 cause injury.
Do not tilt the unit when removing it.
The water inside the unit can spill and wet the furniture and floor.
Be sure to check that the refrigerating cycle section has cooled down sufficiently before
conducting repair work.
Working on the unit when the refrigerating cycle section is hot can cause burns.
Use the welder in a well-ventilated place.
Using the welder in an enclosed room can cause oxygen deficiency.
Warning
Be sure to use parts listed in the service parts list of the applicable model and
appropriate tools to conduct repair work. Never attempt to modify the equipment.
The use of inappropriate parts or tools can cause an electrical shock, excessive heat
generation or fire.
When relocating the equipment, make sure that the new installation site has sufficient
strength to withstand the weight of the equipment.
If the installation site does not have sufficient strength and if the installation work is
not conducted securely, the equipment can fall and cause injury.
Be sure to use an exclusive power circuit for the equipment, and follow the technical
standards related to the electrical equipment, the internal wiring regulations and the
instruction manual for installation when conducting electrical work.
Insufficient power circuit capacity and improper electrical work can cause an electrical
shock or fire.
Be sure to use the specified cable to connect between the indoor and outdoor units.
Make the connections securely and route the cable properly so that there is no force
pulling the cable at the connection terminals.
Improper connections can cause excessive heat generation or fire.
When connecting the cable between the indoor and outdoor units, make sure that the
terminal cover does not lift off or dismount because of the cable.
If the cover is not mounted properly, the terminal connection section can cause an
electrical shock, excessive heat generation or fire.
