INTRODUCTION

The NightFighter Heads-Up Display System is approved

intrinsically-safe and conforms to UL/ANSI 913 for use in

Class I, Div. I, Groups A thru D hazardous locations, tem-

perature rating T1.

Note: The Nightfighter Heads-Up Display System has

een tested and found to comply with the limits for a

lass B digital device, pursuant to Part 15 of the FCC

ules. These limits are designed to provide reasonable

protection against harmful interference in a residential

installation. This equipment generates, uses and can radi-

ate radio frequency and, if not installed in accordance

with instructions, may cause harmful interference to radio

communications. However, there is no guarantee that

interference will not occur in a particular installation. If this

equipment does cause interference to radio or television

reception, which can be determined by turning the equip-

ment off and on, the user is encouraged to try to correct

the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna

• Increase the separation between the equipment and

the receiver

• Connect the equipment into an outlet on a circuit

different from that to which the receiver is connect-

ed.

• Consult the dealer or an experienced radio/TV tech-

nician for help.

1. Read and follow all NIOSH and other approval limi-

tations.

2. Do not use this carrier and harness assembly as a

vertical raising or lowering device.

3. Do not use the air mask as an underwater device.

4. This system must be supplied with respirable

[Quality Verification Level (Grade) D, see ANSI/CGA

G-7.1-1989] or higher quality air; and a dew point

not to exceed -65°F (24ppm v/v) [Compressed Gas

Association Specification G-7.1 for Quality

Verification Level (Grade) D Gaseous Air].

5. This device may not seal properly with your face if

you have a beard, gr

oss sidebur

ns or similar physi-

cal characteristics (see NFPA-1500 and ANSI

Z88.2). An improper facial seal may allow contami-

nants to leak into the facepiece, reducing or elimi

nating respiratory protection. Do not use this

device if such conditions exist. The face-to-face

piece seal must be tested before each use. Never

remove the facepiece except in a safe, non-haz-

ardous, non-toxic atmosphere.

Return to a safe atmosphere immediately if discol

oration, crazing, blistering, cracking, or other dete-

rioration of the lens material is observed.

Users must wear suitable protective clothing and

warnings must be taken so that the air mask is not

exposed to atmospher

es that may be har

mful.

8. Take into account the following factors which may

affect the duration or the service life.

a. the degree of physical activity of the user;

b.the physical condition of the user;

c. the degree that the user’s breathing rate is

increased by excitement, fear, or other emotional

actors;

.the degree of training or experience which the

ser has had with this or similar equipment;

e. whether or not the cylinder is fully charged;

f. the presence in the compressed air of carbon

dioxide concentrations greater than the .04%

level normally found in atmospheric air;

g.the atmospheric pressure; if used in a pressur-

ized tunnel or caisson at 2 atmospheres (15psi

gauge) the duration will be one-half as long as

when used at 1 atmosphere; at 3 atmospheres

the duration will be one-third as long;

h.the condition of the apparatus.

Failure to follow this warning can result in serious per-

sonal injury or death.

• Do not use a 2216psi Air Cylinder on a 3000psi

operating system. Such a configuration is not

approved by NIOSH.

• Do not Transfill (be a Donor) using a 3000psi URC

Assembly. The 3000psi URC Assembly has a check

valve that does not allow cylinders to Transfill (be a

Donor).

• Using the 3000psi URC Assembly to fill cylinders,

the cylinder can only be filled to 2216psig. If the

pressure exceeds 2216psig a relief valve in the

URC Assembly will vent at approximately 2525psig

or as low as 2400psig. A 3000psig cylinder can only

be filled to 3000psig by using a secondary air

source; the 3000psi URC Assembly can not be

used for filling a 3000psig cylinder.

• Do not install a Quick-Fill System and 3000psi URC

assembly on the same air mask. Combining these

assemblies on the same air mask will not allow the

elief valve in the 3000psi URC Assembly to open

as designed.

Failure to follow the above war

nings can result in seri-

ous personal injury or death.

BEFORE USE

Thoroughly inspect this air mask on receipt and before

use. This air mask is to be used only by trained and quali-

fied personnel. Read and understand these instructions

befor

e attempting to use this equipment. If you have any

questions, call toll free 1-800-MSA-2222.
