SECTION 3 − HELMET COOLING SYSTEM
Read and follow these instructions and the safety labels carefully. This product is in-
tended for use as a cooling device only. It is not a respiratory protective device and does
not protect the user from airborne contaminants. Have an industrial hygienist test the air
in your facility to determine if respiratory protection is required to provide adequate
protection from contaminants in your environment. With cooling system-equipped hel-
met on your head and cooling system operating, also test the air inside the helmet to
determine if respiratory protection is required. If you have questions about the type of res-
piratory protection equipment required, consult your safety director and an Industrial
Hygienist.
.
Use the cooling system only with compatible Miller welding helmets (____list?___). See the weld-
ing helmet Owner's Manual for information on helmet operation.
The helmet cooling system draws in air and blows it into the welding helmet shroud through a flexible
connecting hose. The system also generates a positive air pressure to help prevent contaminants
from entering the helmet. The system must include and/or be used with the equipment listed below:
D Helmet and head shroud
D Connecting hose
D Blower assembly with filtration system (spark guard and filter)
D Belt assembly
D Battery charger
The respirator equipment operates at temperatures from 32 to 104° F and provides air flow of 6+ CFM
(low speed) to 7 CFM (high speed) under normal conditions. Battery life is reduced when the unit is
used in a dirty environment. (The blower assembly Batt light goes on when battery power is low.)
