CLEANING AND MAINTENANCE WARNINGS
• Turn off the device and disconnect the power before cleaning. Failure to do so can cause electrical shock.
• Do not clean the air conditioner with excessive amounts of water.
• Do not clean the air conditioner with combustible cleaning agents. Combustible cleaning agents can
cause fire or deformation.
CAUTION
• Turn off the air conditioner and disconnect the power if you are not going to use it for a long time.
• Turn off and unplug the unit during storms.
• Make sure that water condensation can drain unhindered from the unit.
• Do not operate the air conditioner with wet hands. This may cause electric shock.
• Do not use device for any other purpose than its intended use.
• Do not climb onto or place objects on top of the outdoor unit.
• Do not allow the air conditioner to operate for long periods of time with doors or windows open, or if
the humidity is very high.
ELECTRICAL WARNINGS
• Only use the specified power cord. If the power cord is damaged, it must be replaced by the
manufacturer, its service agent or similarly qualified persons in order to avoid a hazard.
• Keep power plug clean. Remove any dust or grime that accumulates on or around the plug. Dirty plugs
can cause fire or electric shock.
• Do not pull power cord to unplug unit. Hold the plug firmly and pull it from the outlet. Pulling directly on
the cord can damage it, which can lead to fire or electric shock.
• Do not modify the length of the power supply cord or use an extension cord to power the unit.
• Do not share the electrical outlet with other appliances. Improper or insufficient power supply can
cause fire or electrical shock.
• The product must be properly grounded at the time of installation, or electrical shock may occur.
• For all electrical work, follow all local and national wiring standards, regulations, and the Installation
Manual. Connect cables tightly, and clamp them securely to prevent external forces from damaging
the terminal. Improper electrical connections can overheat and cause fire, and may also cause shock.
All electrical connections must be made according to the Electrical Connection Diagram located on the
panels of the indoor and outdoor units.
• All wiring must be properly arranged to ensure that the control board cover can close properly. If the
control board cover is not closed properly, it can lead to corrosion and cause the connection points on
the terminal to heat up, catch fire, or cause electrical shock.
• If connecting power to fixed wiring, an all-pole disconnection device which has at least 3mm
clearances in all poles, and have a leakage current that may exceed 10mA, the residual current device
(RCD) having a rated residual operating current not exceeding 30mA, and disconnection must be
incorporated in the fixed wiring in accordance with the wiring rules.
TAKE NOTE OF FUSE SPECIFICATIONS
The air conditioner's circuit board (PCB) is designed with a fuse to provide overcurrent protection.
The specifications of the fuse are printed on the circuit board, such as:
T3.15A/250VAC, T5A/250VAC, etc.
T20A/250VAC(<=24000Btu/h units), T30A/250VAC(>24000Btu/h units)
NOTE: For the units with R32 or R290 refrigerant, only the blast-proof ceramic fuse can be used.
