WARNING
NEVER use a flammable spray such as hair spray, lacquer
or paint near the unit. It may cause a fire.
CAUTION
If this unit is installed indoors, it must ALWAYS be
equipped with an electrically powered safety measure
such as a CO
2
refrigerant leak detector (field supply). In
order to be effective, the unit must ALWAYS be electrically
powered after installation.
If for any reason the CO

2
detector.
CAUTION
To avoid oxygen deficiency, ventilate the room sufficiently
if equipment with burner is used together with the system.
CAUTION
Do NOT operate the system when using a room
fumigation-type insecticide. Chemicals could collect in the
unit, and endanger the health of people who are
hypersensitive to chemicals.

Do NOT remove the front panel. Some parts inside are
dangerous to touch and appliance problems may
happen. For checking and adjusting the internal parts,
contact your dealer.

Do NOT insert fingers, rods or other objects into the air
inlet or outlet. Do NOT remove the fan guard. When the
fan is rotating at high speed, it will cause injury.
