KMB 18 & 28 MANUAL

5.2.1. Component and Parts Cleaning

The mask shell and components should only be
cleaned using a mild solution of dishwashing
detergent such as JOY
washing detergent. Parts that have corrosion
should be washed and scrubbed with a nylon
bristle brush and then soaked in a solution of 50%
white vinegar and water for 30-60 minutes fol-
lowed by a light brushing and a good fresh water
rinse. Hoods and rubber components should be
cleaned using a mild soapy solution followed by
a good rinsing and air-dried. DO NOT use hair
dryers or high heat to dry the rubber or fabric
components, high temperatures will severely re-
duce the serviceability of these components. To
clean metal parts heavily encrusted with salt
we recommend a dilute solution of white
vinegar and a toothbrush.

5.2.2 Component and Parts Lubrication

All parts on the mask that require lubrication must
be lubricated sparingly with food grade silicone
grease. KMDSI recommends Dow corning 111
or equivalent. If the mask is intended to be used
with breathing mixtures greater than 50% oxy-
gen, it should be cleaned for oxygen service, and
components requiring lubrication should be lu-
bricated with a suitable oxygen compatible lu-
bricant such as Krytox
NOT USE AEROSOL SPRAY LUBRI-
CANTS. Many aerosol propellants will damage
plastic. Avoid lubricant contact with plastic parts.
DANGER: All parts on the Kirby

5.2.3. Teflon Tape

Teflon Tape
All pipe thread fittings used on the KMDSI hel-
mets, masks and components require sealing with
Teflon tape. DO NOT USE LIQUID SEAL-
ANT. When installing Teflon tape on pipe
threads, apply the tape starting two threads back
from the end of the fitting. Apply the tape in a
clockwise Direction under tension, 1
all that is needed. Applying more than 1
of tape is not recommended. The use of more than
1
1 / wraps could cause excess Teflon tape to travel

into the breathing system.

DANGER: Do not allow any excess
Teflon tape to enter the breathing system.
Loose pieces of Teflon tape can interfere
with the performance of the one-way valve
or the regulator and may block the diver's
air supply. This could lead to death
through suffocation.

5.2.4 RTV Sealant

Certain components used in KMDSI helmets and
masks use RTV adhesive/sealant to provide bond-
ing and sealing. KMDSI recommends Dow Corn-
ing RTV 732 multi purpose sealant. Caremust
®
be taken to insure excess sealant is wiped clean
and does not to interfere with other components.
Sealant should be allowed to cure for 24 hours
before equipment is used.
DANGER: All parts on the Kirby
Morgan Band Mask 18A/B and 28 must
be adjusted to their proper torque speci-
fications. See Appendix 1 for a complete
listing of torque specifications for each
part. Failure to adjust parts to the recom-
mended specifications could lead to Band
Mask failure and accidents. This could be
fatal.
DANGER: Never use any aerosol
propelled sprays near the face port of the
Kirby Morgan Band Mask 18A/B or 28.
The Freon propellant used in aerosols
can invisibly damage the Lexan
and cause it to shatter upon impact from
any strong blow. If the face port fails
underwater the Band Mask will flood and
drowning may result.
DANGER: The standard Kirby Mor-
gan Band Mask 18A/B or 28 is not in-
tended for nitrox or oxygen service as it
comes from the factory. If the user in-
tends to use this Band Mask for such
service, all parts must be cleaned and
lubricated for oxygen service. Only lubri-
cants such as Krytox
acceptable for oxygen service.
