1.1 PRODUCT DESCRIPTION

Our powerful portable air conditioners are great cooling solutions for

single rooms, creating a comfortable atmosphere in your space. It also

has ventilation and dehumidifying function for circulating air and removal

of moisture. They're self-contained systems that do not require any

permanent installation allowing you to move to the space in which it is

most needed. They're commonly used in kitchen, temporary-resided,

computer rooms, garages, and many other places where installation of

Air-conditioner Outdoor Unit is limited.

The environmentally friendly R290 is used as the refrigerant. R290 has no

damaging influence on the ozone layer (ODP), a negligible greenhouse

effect (GWP) and is available worldwide. Because of its efficient energy

properties, R290 is highly suitable as a coolant for this application. Special

precautions must be taken into consideration due to the coolant's high

flammability.

1.2 SYMBOLS FROM THE UNIT AND USER MANUAL

This unit uses a flammable refrigerant.

If refrigerant leaks and comes in contact with fire or heating

warning part, it will create harmful gas and there is risk of fire.

Read the USER MANUAL carefully before operation.

Further information is available in the USER MANUAL,

SERVICE MANUAL, and the like.
