STORAGE
STORAGE
•
Ensure that the unit is working properly before
storage by temporarily installing a battery and
check the airflow as instructed in the Before Use
section. Remove the battery after testing.
•
DO NOT store the unit with the battery installed.
Always remove the battery from the blower assem-
bly for storage. Store the battery and the blower
assembly away from sunlight, heat, or moisture.
Storing the Respirator
•
Install the green seal plugs over the outlet and into the
canister mounting ports of the blower assembly.
•
Install the green seal plugs over the outlet and into the
blower inlet of the PAPR breathing tube extension.
The PAPR breathing tube is not stored in any addition-
al packaging.
•
Store only undamaged respirators and breathing tubes
for further use. When not in use, store the respirator in
cool, dry, and clean ambient air.
•
Canisters must be stored in original, unopened foil
bag and in the original, unopened carton.
•
The APR breathing tube must be stored in the provid-
ed plastic drawstring bag (p/n 465008). Replace the
bag if it becomes damaged.
The facepiece must be stored in the facepiece bag (P/N
805029) with the lens cover label (P/N 10082547) in place
and the black plastic cap (P/N 10086013) installed on the
facepiece inlet connection. The facepiece bag is provided
as a convenient storage container to protect the face-
piece. Replace the facepiece bag if it becomes damaged.
Storing the Batteries
•
Store the batteries in normal conditions (room temper-
ature/ 50% relative humidity/away from direct sun-
light).
•
The LI-SO2 battery is designed for extended shelf life
when properly stored. The LI-SO2 battery is not
rechargeable.
•
The NiMH battery is rechargeable. Follow the instruc-
tions on the battery label or refer to the Charging the
C420 Rechargeable Battery section of this manual.
•
Keep this user’s instruction manual with the complete
respirator.
CHARGING THE C420 RECHARGEABLE BATTERY
Charging the C420 Rechargeable Battery
Note:
Before initial battery pack use, or if battery pack
has not been used for an extended period of time (several
months), perform (3) 6-hour charge/4-hour discharge
cycles for optimum battery performance. The discharge
cycles should be completed with the blower running in a
non-hazardous environment, with no breathing tube or
canisters attached to the blower.
1. Place the charger horizontally on a flat surface and in
a dust-free area with a temperature range between
32°F and 100°F (0°C and 37.7°C). The ideal tempera-
ture is 70°F (21.1°C).
2. Insert the appropriate cord set (120v or 230v) into the
IEC receptacle on the charger. Plug the charger AC
power cord into the appropriate regulated 120v or
230v outlet. The “ORANGE” LED will illuminate when
no battery is plugged in or during battery charging ini-
tialization.
3. Align the keyed charger plug with the charging recep-
tacle in the battery pack and fully insert. The “RED”
LED will illuminate, indicating that the connected bat-
tery pack is being charged in the “Fast Charge Rate”
mode.
Note:
In a discharged condition (approximately 4 hours of
operational use), the battery pack will charge for approxi-
mately 6 hours. Charging times will vary for battery packs
in a partial charge state.
•
The positive and negative battery terminals of the
battery pack are on the opposite end from the
charging receptacle. DO NOT ground out the posi-
tive terminal (center metal circle) and the negative
terminal (outer metal ring). Doing so could short
circuit the battery pack, resulting in excessive cur-
rent flow and could cause battery liquid electrolyte
leakage, heat generation, bursting and fire.
•
Use extreme caution not to ground out the metal
charging leads on the battery charger plug, as
doing so could result in damage to the battery
charger.
Failure to follow the above warning can result in seri-
ous personal injury or death.
4. When the “GREEN/ORANGE” LEDs illuminate, the
charger has switched to a “Top-Off Charge” mode,
indicating the battery is nearly fully charged.
5. The “GREEN” LED indicates the battery is fully
charged and is in the “Trickle Charge” mode. The opti-
mum charging time is 8 hours. Battery packs can be
left in a “Trickle Charge” mode indefinitely.
New batteries, and batteries not used for months,
could experience a false indication that can cause the
“GREEN” LED indicator to illuminate only a few min-
utes into the charging cycle. Unplug and then re-plug
to continue the charging cycle
.
