Honeywell also recommends a full fl ow test be per-
formed per NFPA 1852, Standard on Selection, Care,
and Maintenance of Open-Circuit Self-Contained
Breathing Apparatus (SCBA), 2013 Edition (or latest
edition) for additional inspection requirements for
SCBAs used for fi refi ghting.
E. Repair (see Repair Table, page 28)
WARNING
Before disassembly, make sure that all air is
bled from the lines. Shut off or deplete the
air supply to prevent equipment damage or
personal injury. Failure to comply with this
warning may lead to personal injury, illness,
or death.
CAUTION
User repair of the Honeywell SCBA is
limited to replacement of components listed
on the NIOSH CBRN approval label and
repair described in the repair table in this
manual. Disassembly should be performed
only to the extent necessary to replace the
components. To protect your warranty and
the NIOSH certifi cation on the equipment,
all other repairs must be done only by
Honeywell-certifi ed technicians. If there are
none at your facility, consult your Honeywell
distributor for the repair facility nearest you.
NOTE
All Honeywell-certifi ed Technicians are required
to remain current on new procedures and
parts through Honeywell's published Technical
Bulletins, technical manual revisions, and
certifi cation seminars.
f. functional Testing (see page 29)
Perform functional tests after cleaning or repair.
G. Cylinder Recharging
Refer to section VII., Cylinder Filling and Safety, for
details on the recharging procedures for cylinders ap-
proved for use with Honeywell SCBAs.
H. Cold Weather Operation and Maintenance
Operation of the Honeywell SCBA in cold weather,
32°F (0°C) or colder, requires the user to be aware of
the potential problems caused by the combination of
moisture and low temperatures.
WARNING
• Moisture entering the regulator system,
either from moisture in the cylinder air or
by external means, e.g., inclement weather
conditions, may cause regulator system
freezeup, restricting or stopping air fl ow to
the user. This could result in injury or death
to the user.
• Recharge the cylinders with Grade D or
better air conforming to Compressed Gas
Association Specifi cation G-7.1. Moisture
content, expressed as dewpoint, shall be

WARNING—Continued
maintained at -65°F (-53.9°C) or lower, or
less than 24.0 ppm by volume. Air exceeding
this moisture content may cause regulator
system freezeup, restricting or stopping air
fl ow to the user. This could result in injury or
death to the user.
NOTE
• Moisture can cause regulator system freezing
problems even if the ambient air temperature is
above freezing. The air fl owing from the SCBA
cylinder through the regulator system decreases
from cylinder pressure to near atmospheric
pressure
very
rapidly. As
decreases, the air rapidly expands, causing the
air and therefore the regulator to cool.
• Although the ambient temperature may be
above 32°F (0°C), the temperature inside the
regulator system may be considerably lower
(below freezing).
• Honeywell recommends that SCBAs used on
a routine basis or SCBAs kept for emergency
use be stored at temperatures above 32°F
(0°C). SCBAs stored at temperatures below
32°F (0°C) may need to be warmed to at least
32°F (0°C) prior to use if ice has formed on the
low pressure alarm, facepiece exhalation valve,
AIR KLIC, and/or quick-disconnects.
• Honeywell recommends a "change of season"
inspection and increased attention to your
preventive maintenance during cold weather
conditions.
The
following
inspections and procedures will help prevent
cold weather problems; however, cold weather
conditions may also cause other problems not
listed below.

1. Air Supply

NOTE
Cold weather conditions require very dry air.
Moisture entering the SCBA may cause icing
and equipment malfunction.
a. Test compressor(s) for air quality and dewpoint
prior to the cold season.
b. Recharge the cylinders with Grade D or better air
conforming to Compressed Gas Association Speci-
fi cation G7.1. Moisture content, expressed as dew-
point, shall be maintained at -65°F (-53.9°C) or lower,
or less than 24.0 ppm by volume.
c. Prevent any moisture from entering the SCBA.
d. Remove ice and water from cylinder valve threads
prior to fi lling in cold weather conditions.

2. Facepiece and Exhalation Valve

a. The facepiece must be protected from moisture
during cold weather conditions to reduce ice forma-
tion on the facepiece lens, in the AIR KLIC, and in the
exhalation valve.
