Extended Runs Using the Charger
Extended operation is possible in
nonhazardous locations
using the pump with its
battery charger plugged into a wall outlet.
The battery will discharge during an extended run. However, when the charge
drops by 50%, the fast charge feature is initiated until the battery receives a full
charge. This cycle repeats every several hours during operation.
Do not charge or operate the pump with the charger in hazardous locations.
Use of any device other than the approved battery pack to power the pump voids
the UL Listing for intrinsic safety.
Note:
Determining Battery Charge Level
• The pump will operate for up to 12 hours with a NiMH battery (eight hours with
NiCad) at a flow rate of 200 ml/min and back pressure of 10 inches of water. Pump
operation time will increase as flow rate and back pressure rates are decreased.
• The LCD shows the current battery charge level. The icons appear as follows:
Three bars indicate a full charge (normally appear after charging), approximately
70 to 100%.
Two bars indicate that the battery is charged enough to operate the pump,
approximately 15 to 70%.
One bar indicates battery charge is low (charge battery), approximately less than
15%.
When the battery has lost all of its charge, all bars are clear and the outline is
flashing. The pump goes into HOLD mode and then to SLEEP mode in ap-
proximately one minute.
