INTRODUCTION
The Flow-Check Meter from MSA is used to verify the
minimum required air flow rates on the following respira-
tors from MSA:
• constant-flow air-line respirators with tight-fitting face-
pieces;
• constant-flow hoods which utilize a valve-connector;
• powered air-purifying respirators (PAPR) which use
tight-fitting facepieces;
• powered air-purifying mask-mounted respirators
(PAPR) with full facepiece.
The Flow-Check Meter from MSA must not be used to
set the flow rate for the respirator. The flow rate must
be set by adjusting the inlet pressure to the respirator
as specified in the NIOSH approval for the respirator.
USE
All Respirators:
Assemble the complete respirator following the instruc-
tions supplied.
Do not remove the breathing tube, motor-blower or fil-
ter in a hazardous environment. All testing must be
done in a non-hazardous area. Failure to follow this
precaution may cause inhalation of contaminants and
result in severe respiratory injury or death.
CONSTANT-FLOW AIR-LINE RESPIRATORS, AS WELL
AS THE POWERED AIR-PURIFYING RESPIRATORS
(PAPR) BREATHING TUBE FROM MSA WHICH USE
TIGHT-FITTING FACEPIECES
1. Remove the breathing tube from the facepiece and
connect the Flow-Check Meter coupling nut to the
breathing tube.
Note: If an adjustable valve-connector is used, fully close it.
2. Turn the air source on.
3. Hold the Flow-Check Meter in the vertical position to
obtain accurate readings.
Do NOT block the vertical tube slots or filter during
the test. Inaccurate readings will result.
4. Read the position of the ball. The ball must be above
the LOWER line marked “ENTIRE BALL MUST BE
ABOVE THIS LINE FOR RESPIRATORS WITH FACE-
PIECES”.
If the respirator meets the minimum flow requirements, it
is ready for use. If the respirator does not meet the mini-
mum flow requirements, locate and correct the cause of
the low flow rate before using respirator.

CONSTANT-FLOW HOODS FROM MSA WHICH USE A
VALVE-CONNECTOR
Testing PAPR with Hood must use Adapter P/N 489999
1. Remove the breathing tube from the valve-connector
and connect the Flow-Check Meter coupling nut to
the valve-connector.
Note: If an adjustable valve-connector is used, fully close it.
2. Turn the air source on.
3. Hold the Flow-Check Meter in the vertical position to
obtain accurate readings.
Do NOT block the vertical tube slots or filter during
the test. Inaccurate readings will result.
4. Read the position of the ball. The ball must be above
the UPPER line marked.
“ENTIRE BALL MUST BE ABOVE THIS LINE FOR
RESPIRATORS WITH HOODS”.
If the respirator meets the minimum flow requirements, it
is ready for use. If the respirator does not meet the mini-
mum flow requirements, locate and correct the cause of
the low flow rate before using respirator.
MASK MOUNTED POWERED AIR-PURIFYING
RESPIRATOR (PAPR) WITH FULL FACEPIECE
1. Remove the motor blower module from the mask.
2. Thread Mask Mounted Adapter (P/N 491046) to Flow-
Check Meter.
3. Thread the motor blower module into Mask Mounted
Adapter.
4. Turn ON the PAPR power switch.
5. Hold Flow-Check Meter in a vertical position to obtain
accurate readings.
Do NOT block the vertical tube slots or filter during
the test, inaccurate readings will result.
6. Read the position of the Ball.
• Ball must be above the lower line marked. ENTIRE
BALL MUST BE ABOVE THIS LINE FOR RESPIRA-
TORS with FULL FACEPIECES.
7. If the respirator meets the minimum flow requirements,
it is ready for use. If the respirator does not meet the
minimum flow requirements, locate and correct the
cause of the low flow rate before using the respirator.

MAINTENANCE
The Flow-Check Meter must be clean to ensure accurate
readings. Dirt on the inside of the tube or on the indicating
ball must be removed before the meter is used. The meter
may be cleaned using ConfidencePlus™ Cleaning
Solution (P/N 10009971) from MSA or a mild cleaning
solution. Follow the instructions supplied with the cleaning
solution.
The Flow-Check Meter should be inspected regularly for
cracks, chips or other signs of physical damage. The
meter must be replaced if damaged.
