2. Inhale, then hold your breath. No entry of air should be perceived, otherwise
check if the facepiece was donned correctly.
The exhaled air must escape through the exhalation valve without
resistance.
3. Repeat the fit test twice.
4. Screw the canister into the connector until it is tightly seated. Have a second
person check the firmness and correct connection.
4.1.4.2 Facepiece with P-type connector
Choose either method C or method D to check tight fit of the facepiece.
Method D allows you to keep the air-supply system connected to the facepiece.
4.1.4.2.1 Method C
1. Put lung demand valve in the connector.
2. Turn and pull the lung demand valve to check for tight fit. Have a second
person check the firmness and correct connection.
3. Close the medium pressure hose with your thumb.
4. Inhale, then hold your breath. No entry of air should be perceived, otherwise
check the tight fit of the facepiece.
The exhaled air must escape through the exhalation valve without
resistance.
5. Repeat the fit test twice.
6. Connect self-contained breathing apparatus or airline breathing apparatus
to the lung demand valve.
4.1.4.2.2 Method D
If lung demand valve and air-supply system are already connected to the
facepiece, proceed as follows:
1. Inhale and hold your breath - there should be no audible leak.
2. Recommence breathing - exhaled air should easily flow out of the
exhalation valve.
3. Close the air-supply system, and breathe normally to empty the system.
When the pressure gauge indicates zero (system empty), inhale and hold
your breath for approximately 8 seconds. The facepiece should hold on to
the face indicating a positive seal.
4. Open the air-supply system again.

WARNING
Risk of poisoning

is danger of serious injury or death due to exposure to smoke, chemicals, or
other harmful substances, including but not limited to poisoning.
When the facepiece is used with a canister,
● the ambient air must contain at least 19.5 % of oxygen; observe country-
specific regulations.
● never enter unventilated tanks, pits, canals, etc.
● the type of pollutants must be known. Choose corresponding canister.

bubbles in the visor.
The coating may dissolve in some places in visors marked with PCas and PCaf.
The facepiece is fully serviceable until the end of the operation. Replace visor
after use.
