This group of symbols means Warning! Watch
Out! ELECTRIC SHOCK, MOVING PARTS,
and HOT PARTS hazards. Consult symbols
and related instructions below for necessary
actions to avoid the hazards.
. Indicates special instructions.
DANGER! − Indicates a hazardous
situation which, if not avoided, will
result in death or serious injury. The
possible hazards are shown in the
adjoining symbols or explained in
the text.

NOTICE − Indicates statements not related to
personal injury.
1-2. Hazards
Only qualified persons should install, operate, maintain, and repair this unit.
READ INSTRUCTIONS.
D Read and follow all labels and the Owner’s Manual carefully before installing,
operating, or servicing unit. Read the safety information at the beginning of
the manual and in each section.
D Use only genuine replacement parts from the manufacturer.
D Perform maintenance and service according to the Owner’s Manuals, industry standards,
and national, state, and local codes.
HELMET COOLER MISUSE can be hazardous.
Welding produces fumes and gases. Breathing these fumes and gases can be hazardous to your health.
D Read and follow these instructions and the safety labels carefully. This
product is intended 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 helmet on, also test the air inside the helmet to determine if respiratory protection is required. If you have questions about the
type of respiratory protection equipment required, consult your safety director and an Industrial
Hygienist.
D Do not use this product where there is danger of fire or explosion.
D Do not use this product in windy conditions or negative pressure inside the hood may draw in
contaminants from the outside air.
D Do not use this product without a properly installed spark guard unless the unit is designed and
intended to be used without one. Without the spark guard (on applicable products), welding
sparks may ignite the filter or damage the filter.
D This product does not supply oxygen. Do not use this product where oxygen levels are 19.5% or
lower, where contaminant levels are unknown or are immediately dangerous to life or health
(IDLH), or where the contaminant levels exceed the equipment specifications.
D Do not enter a work area until you are sure the equipment is correctly assembled, working proper-
ly, and properly worn.
OM-235 368 Page 2
D Before each use, inspect the equipment for damage and verify it operates properly.
D Dangerous contaminants may not smell or be visible. Leave the area immediately if you notice
the following:
Breathing becomes difficult.. . .
You experience dizziness, impaired vision, or eye, nose, or mouth irritation.. . .
The equipment is damaged.. . .
D Do not repair, modify, or disassemble this product or use with parts or accessories not supplied by
the manufacturer.
D Do not operate unit without properly installed filter(s). Replace damaged or clogged filters. Do not
wash or reuse filters. Do not clean filters by tapping or with compressed air or filter elements may
be damaged.
D Do not restrict or alter helmet cooler air flow. Do not block air inlet or outlet. Be sure safety
glasses, hair, weld cap, and other objects do not block air flow.
D This product contains electrical parts which have not been evaluated as an ignition source in
flammable or explosive atmospheres by MSHA/NIOSH.

SECTION 3 − HELMET COOLING SYSTEM
Read and follow these instructions and the safety labels carefully. This product is intended 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 helmet 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 respiratory 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.)
