Battery Storage
Storage of Li Polymer batteries is relatively easy. Unlike Nickel batteries, they
lose a very small amount of power (less than 0.5% per day) and therefore can
be charged and stored ready for use. If long-term storage is required, it is best
to store the battery in a cool place with at least 40% charge still remaining.
NOTE
Discharging and re-charging the battery fully at least once every 3 months
is suggested to ensure the longest possible life of the battery.
To maximize battery life, these guidelines should
be followed:
• Remove the battery from the blower unit when not in use.
• Charge the battery before it is completely discharged. The low battery
alarm indicates that the battery needs to be charged. The battery is
designed with a circuit to protect the battery. It will not allow the battery
to be discharged below a safe voltage for the cells, regardless of airflow,
without the alarm sounding. When the battery reaches the voltage cutoff it
will automatically cease operation.
• Always charge the batteries at room temperature or cooler. At higher
temperatures, the battery pack may not accept a full charge. If the battery
pack feels hot, let it cool for 30 minutes before charging.
• Do not charge battery packs in an enclosed cabinet without ventilation.
• Battery capacity may be checked with a diagnostic charger (special order).
• Table-top gang chargers (Part No. EVAGC with 6 ports) are also available.
Battery Fuel Gauge:
EVA Battery Packs are equipped with
an on-board fuel gauge to indicate the
amount of remaining capacity left in
the battery pack. To check the remain-
ing capacity, simply depress the button
labeled “Push” and LEDs will illuminate
indicating the level of battery capacity remaining. When fully charged all four
LEDs will illuminate green, and when 25% or less charge is available a single
LED will illuminate red.
Pre-Operational Inspection
Prior to each work shift, perform the following Pre-Operational Inspection to
ensure proper operation and to ensure that the unit is completely assembled.
1. Belt Mounted Blower Unit, Part No. EVA1
• Check that the unit is clean and undamaged.
• Inspect for deterioration, physical damage and improper assembly.
2. Filter/Cartridges
• Inspect the filter/cartridge for any physical damage
• Check the label to ensure the filter/cartridge has not exceeded its
“use-by” date.
• Inspect the gasket on the filter for any physical damage.
NOTE
Each filter comes with a permanent gasket.
• Ensure that the correct filter/cartridge is appropriate for the contaminant.
• 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.
• Screw the cartridge into the port until hand-
tight and the locking tab is secure. (Refer to
Mounting and Replacing Filters on Blower
Unit on page 5)
3. Battery Pack
NOTE
The EVABAT2 is green and is not for use
with Loose Fitting Hoods or Loose Fitting
Face Pieces.
• Check that the battery is not damaged.
• Check the Fuel Gauge to determine sufficient charge is available.
• Place the battery pack in the battery compartment on the blower.
• The battery tab should click when completely engaged. (See Figure 4)
4. Half Face Mask and Breathing Tube
• Inspect the full face mask for any physical damage, such as torn head harness
straps, scratched or cracked visor and distortion of the rubber flange.
• Inspect the breathing tube for tears, cracks, holes or excessive wear that might
reduce the degree of protection originally provided.
• Replace any damaged parts with the proper Bullard replacement part to
maintain the NIOSH approval.
Mounting the Breathing Tube on the 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 5).
• 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 by pressing the on/off
button for 1-2 seconds confirmed by a short
beep.
• If the Low Battery Alarm sounds at this
time, the battery needs to be recharged. See
instructions on page 2 regarding properly
charging the battery.
• If the Low Flow Alarm sounds after the
blower reaches full speed, then the mask,
breathing tube and filter should be check for a blockage.
DO NOT
charge batteries in hazardous areas.
