6. BATTERIES AND CHARGER
The
SAM™ SMART NOZZLE comes with Akron Brass P/N 803435 Lithium-ion rechargeable batteries. The
batteries must be fully charged prior to first use. Akron Brass recommends using the Tenergy TN471U
battery charger. Akron Brass internal P/N for this charger is 60470010.
Using any battery other than Akron Brass P/N 803435 can potentially damage
your
SAM™ SMART NOZZLE. Failure to use the specified battery increases
the chance of fire and will void your warranty.
6.1 Charging Batteries
Lithium-ion batteries do not have a charge memory, so deep discharging is not required. It is better to use
partial discharge cycles. After 30 charges, you should completely discharge batteries prior to charging.
The battery is considered completely discharged when it measures less than 3.2 V.
6.2 Installing Batteries
To prevent ignition of a hazardous atmosphere, batteries must only be
changed in an area known to be nonhazardous.
Change batteries in a clean dry area to avoid internal electrical
contamination.
Only one battery is required to power the
SAM™ SMART NOZZLE. For
maximum life, install two batteries.
Unscrew the battery cap thumbscrew by turning it counterclockwise and remove the battery cover. Remove
the depleted batteries and place in the battery charger for recharging. Insert freshly charged batteries.
Observe polarity for proper (+) and (-) placement. Before replacing the battery cover, inspect and remove
any dust or dirt on the mating surfaces of the battery cover and housing. Replace battery cap and tighten
the thumbscrew until it will not turn.
