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 not below -5ºC/23ºF 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. Do not leave on 
the charger for more than 30 consecutive days.

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 tem-

peratures, 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 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 remaining 
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 4)

3. Battery Pack 

  •  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.  Hood with Suspension or Hard Hat, or Loose Fitting Facepiece 

  •  The hood is constructed of one of the following materials: Tychem 2000 (QC), 

Tychem 4000 (SL) or Nomex (GRH). 

  •  Depending on the model of the hood selected, it may be used with either 

a headband suspension or a hard hat (Note: RT Series hoods are NIOSH 
approved without a headband suspension or a hard hat). 

  •  The loose fitting facepiece is constructed of Tychem 2000 (QC) and features an 

internal suspension. 

  • Inspect the hood or loose fitting facepiece for any physical damage.

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 at this 

time, the hood, breathing tube and filter 
should be check for a blockage.

DO NOT

 charge batteries in hazardous areas.
