WARNING: FLAMMABLE MATERIALS

DO NOT USE MEANS TO ACCELERATE THE DEFROSTING

PROCESS OR TO CLEAN, OTHER THAN THOSE RECOMMENDED

BY THE MANUFACTURER. THE APPLIANCE SHALL BE STORED

IN A ROOM WITHOUT CONTINUOUSLY OPERATING IGNITION

SOURCES (FOR EXAMPLE: OPEN FLAMES, AN OPERATING

GAS APPLIANCE OR AN OPERATING ELECTRIC HEATER. DO

NOT PIERCE OR BURN. BE AWARE THAT REFRIGERANTS MAY

NOT CONTAIN AN ODOR.

If any hot work is to be conducted on the refrigerating

equipment or any associated parts, appropriate fire

extinguishing equipment shall be available on hand. Have

a dry powder or CO

fire extinguisher adjacent to the

charging area.

Ensure that the area is in the open or that it is

adequately ventilated before breaking into the system

or conducting any hot work. A degree of ventilation

shall continue during the period that the work is carried

out. The ventilation should safely disperse any released

refrigerant and preferably expel it externally into the

atmosphere.
