1-2. Hazards
Only qualified persons should install, operate, maintain, and repair this
unit.
READ INSTRUCTIONS.
DRead and follow all labels and the Owner’s Manual carefully be
-
fore installing, operating, or servicing unit. Read the safety in
-
formation at the beginning of the manual and in each section.
DUse only genuine replacement parts from the manufacturer.
DPerform maintenance and service according to the Owner’s Manuals, industr
y
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.
DRead 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 de-
vice and does not protect the user from airborne contaminants. Have an
industrialhygienist test the air in your facility to determine if respiratory protec-
tion 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 a certified In-
dustrial Hygienist.

OM-262 902 Page 4
DDo not use this product where there is danger of fire or explosion.
DDo not use this product in windy conditions or negative pressure inside the
hood may draw in contaminants from the outside air.
DDo 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.
DThis 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 imme-
diately dangerous to life or health (IDLH), or where the contaminant levels
exceed the equipment specifications.
DDo not enter a work area until you are sure the equipment is correctly as-
sembled, working properly, and properly worn.
DBefore each use, inspect the equipment for damage and verify it operates prop-
erly.
DDangerous contaminants may not smell or be visible. Leave the area immedi-
ately if you notice the following:
Breathing becomes difficult.....You experience dizziness, impaired vision, or eye, nose, or mouth irritation.....The equipment is damaged.....
DDo not repair, modify, or disassemble this product or use with parts or accesso-
ries not supplied by the manufacturer.
DDo 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.
DDo 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.
DThis product contains electrical parts which have not been evaluated as an igni-
tion source in flammable or explosive atmospheres by MSHA/NIOSH.

SECTION 3 − HEADGEAR COOLING SYSTEM
Read and follow these instructions and the safety labels carefully. This
productis intended for use as a cooling device only. It is not a respiratory pro-
tective 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 res-
piratory protection equipment required, consult your safety director and an
Industrial Hygienist.
.Use the cooling system only with compatible Miller welding helmets (MP-10t,
Pro-Hobbyt, Performancet, Elitet, Titaniumtseries helmets). See the welding
helmet Owner’s Manual for information on helmet operation.
The CoolBandtheadgear cooling system draws in air and blows it to the front of the weld-
ing helmet through a flexible tube. 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:
DHelmet and cowl (head shroud)
DBlower assembly with properly-installed filter
DBattery charger
The headgear cooling system operates at temperatures from 14°⎫↵131°F (−10°to 55°
C). The Battery Level red light flashes and blower assembly pulses on and off when bat-
tery power is low.

tures, the headgear cooling system
is shown without welding helmet.
