Initial Charging Procedure with Quick Charger
To ensure a full charge on a new battery pack, follow these important guidelines.
These guidelines also apply to battery packs that have been in storage for
extended periods of time.
For new battery packs or packs that have been in storage for extended periods of
time, follow the directions above under “Battery Pack”, and when the light turns
green (PA3ISBP), do the following:
• Remove the battery pack. Wait 15 seconds. Replace the battery pack in the
nest. The charger light will now turn red (PA3ISBP).
• When the light turns green (PA3ISBP), remove the battery pack. Wait 15
seconds. Replace the battery pack in the nest again. The charger light will now
remain on or turn red.
The charger light will turn green (PA3ISBP), indicating that the battery is fully
charged.
This procedure should also be followed after periods of prolonged storage.
Without periodic charging, the nickel metal hydride batteries will lose up to
1%–2% of their charge per day. Allowing a battery to self-discharge during
periods of prolonged storage will not damage the battery.
WARNING
DO NOT
charge batteries in hazardous area.
Pre-Operational Inspection
Prior to each work shift, perform the following Pre-Operational Inspection to
ensure proper operation and to insure that the unit is complete.
1. Belt Mounted Blower Unit, Part No. PA3ISBU
• Check that the unit is clean and undamaged.
• Inspect for deterioration, physical damage, and improper assembly.
• Ensure that the correct filters/cartridges for the appropriate contaminant
are properly mounted on the blower unit. Screw the cartridges into the
ports until hand-tight.
Consult the NIOSH approval label and your own in-plant safety professional if
you have any questions as to the suitability and efficiency of the Air-Purifying
Element.
2. Battery Pack
• Check that the battery is not damaged.
• Place the battery pack in the battery compartment on the blower by first
engaging the tab on the pack under the lip on the edge of the compartment.
Then close the latch.
3. Hood with Suspension or Hard Hat, or Loose Fitting Facepiece
• The hood is constructed of either DuPont
™
Tychem
®
QC or Tychem SL.
Depending on the model selected, it may be used with either a headband
suspension or a hard hat. The loose fitting facepiece is constructed of
Tychem QC and features an internal suspension.
• All hoods and loose fitting facepieces are approved for use with the
PA3ISBU Blower Units.
• Inspect the hood or loose fitting facepiece for any physical damage.
Mounting the Breathing Tube on the PA3ISBU Blower
Ensure that a rubber gasket is in place in the breathing tube coupler on the
blower unit.
Screw one end of the
breathing tube into the
blower unit (hand tight is
sufficient)
(see Figure 2)
.
Ensure that neither the
breathing tube nor the filter
is blocked.
Ensure that the ON/OFF
Switch is in the OFF position.
Switch on the blower. If the Low Voltage Alarm sounds
at this time, the battery needs to be recharged. See
instructions on page 2 regarding properly charging the battery.
Checking Airflow with the Airflow Indicator (PA1AFI)
With the blower switched ON and the filters/cartridges mounted, take the free
end of the breathing tube in one hand, hold it
upright and place the Airflow Indicator into
the end of the tube
(see Figure 3
).
Apply a light downward pressure to the
Airflow Indicator to get a reasonable seal
at the breathing tube end. Ensure that the
air outlet holes in the Airflow Indicator tube
are not blocked. Two hands may be used if
preferred, one to hold the breathing tube and
one to hold the Airflow Indicator.
The position of the ball in the Airflow
Indicator should be observed. If any part of
the ball is below the PASS LINE on the Airflow
Indicator, check for:
• Blower malfunction.
• Clogged or damaged Air-Purifying filter elements on the HE filters or the
combination cartridges with HE filters. See “Mounting and Replacing
Cartridges on the Blower Unit” on page 5.
• Low voltage or battery malfunction.
If the ball is completely above the PASS LINE on the Airflow Indicator, then the
system is ready for use.
When the blower passes the flow test, it is ready to use. 䍃
WARNING
If the blower malfunctions during use in a hazardous area:
DO NOT
remove the respirator hood, blower or waist-belt while in the
hazardous area.
DO
remain calm and
LEAVE
the hazardous area immediately.
After reaching a hazard-free area, immediately remove the respirator.
DO NOT
use a blower that fails the flow test.
Use
ONLY
Bullard cartridges which comply with and have the NIOSH
approval label and which are appropriate for the contaminant.
Failure to observe these warnings could result in death or serious injury.
