NOTE ON FLUORINATED GASES:
1. This unit contains fluorinated greenhouse gases.
2. For specific information on the type of gas and the amount, please refer to the relevant label on
the unit itself.
3. Service, maintenance, and repair of this unit must be performed by a certified technician.
4. Product un-installation and recycling must be performed by a certified technician.
5. For equipment that contains fluorinated greenhouse gases in quantities of 5 tonnes of CO
2
equivalent or more, but less than 50 tonnes of CO
2
equivalent, and has a leak-detection system
installed, it must be checked for leaks at least every 24 months.
6. Keeping a record of all leak checks for the lifetime of the unit is strongly recommended.
CAUTION
DO NOT allow the air conditioner to operate for extended periods of time with the doors or
windows open, or in very high humidity.
DO NOT use the device for any other purpose than its intended use.
DO NOT climb onto or place objects on top of the outdoor unit.
1. Turn off the air conditioner and disconnect the power if it is not going to be used for an
extended period of time.
2. Turn off and unplug the unit during storms.
3. Some parts of the unit are very sharp and can cause injury if touched. To prevent this, always wear
gloves when installing or servicing the unit.
4. Ensure water condensate from the unit can flow freely through the condensate drain pipe.
17. The product must be properly grounded during installation or electrical shock could occur.
18. For more information on how to install the appliance to its support, please refer to the indoor unit
installation and outdoor unit installation sections of this manual.
19. Keep the power plug clean and remove dust or grime that accumulates around the plug. A dirty plug
could cause fire or electric shock.
20. Dispose of this unit’s packaging carefully and ensure children do not play with it. The packaging for
this unit, especially plastic components, can be dangerous and can cause serious injury or death.
Screws, staples, and other metal packaging components can be sharp and can also cause injury.
21. The refrigerant in the unit is safe and should not leak if the system is installed properly. However, in
the event that a large amount of refrigerant leaks into a room, the oxygen concentration will decrease
rapidly. This can cause serious injury or death. The refrigerant is heavier than air, so the danger is
greater in basements or other underground spaces. Should a refrigerant leak occur, turn off any
devices that produce a naked flame and any heating devices (toxic fumes could be produced if
refrigerant comes in contact with them), ventilate the room, and contact your supplier or service
technician immediately.
WARNING
TAKE NOTE OF FUSE SPECIFICATIONS
The air conditioner’s circuit board (PCB) is designed with a fuse to provide over-current protection.
The specifications of the fuse are printed on the circuit board. Examples of this include,
T5A/250VAC and T10A/250VAC.
