Battery Pack
A fully charged battery pack will power a blower unit to provide
adequate air volume for the respirator for approximately four to
eight hours for the PA3BU under normal working conditions,
depending on whether one or two battery packs are used.
A fully charged battery pack will power a blower unit to provide
adequate air volume for the respirator for approximately seven
hours for the PA3ISBU.
To charge the battery pack, do the following:
• Open the battery latch and remove the battery from the back of
the blower.
• Place each battery in the charging ports of the battery charger.
Ensure that the battery contacts line up with the contacts in the
charger port
(see Figure 1)
.
• Connect the battery charger to a 115-volt AC electrical outlet.
Charge the battery pack for approximately eight hours.
While the PA3BP battery is charging, the light on the charger will
remain on. The charger light will flash when charging is complete.
While the PA3ISBP battery is charging, the light on the cord will
remain red. When the unit is charged, it will turn green.
Table-top gang chargers (Part No. PA3GC, with 5 ports, and Part
No. PA3ISGC, with 6 ports) are also available.
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 begins to flash on the charger
or 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 remain on (PA3BP)
or turns red (PA3ISBP).
• When the light begins flashing again (PA3BP), or 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 flash a third time (PA3BP), or 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.
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. PA3BU/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. Place a
second battery pack in the other compartment, if desired
(PA3BU only). If only one battery is used, install the PA3BPC
battery port cover over the unused port (for PA3BU).
3. Hood with Suspension or Hard Hat, or Loose Fitting
Facepiece
• The hood is constructed of either 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 PA3BU and PA3ISBU Blower Units.
• Inspect the hood or loose fitting facepiece for any physical
damage.

PA3BP battery packs
MUST
be used with PA3 blower units and
PA3ISBP intrinsically safe battery packs
MUST
be used with
PA3IS blower units. Interchanging these batteries with blowers
may cause damage to the blower and battery
AND
the blowers
will not operate as intended and may put the wearer at risk.
Failure to follow these instructions may result in death or
serious injury.
