Maintenance
Cleaning
Clean exterior and interior surfaces of the housing and control panel using a dry
or damp cloth with mild detergent. Never immerse nor use excess fl uid.
CAUTION:
Immersion or submersion of the unit will result in improper
operation and possible damage to the unit.
Internal Battery
Th
e internal battery is spill-proof and sealed, has no serviceable internal parts
or components and is constructed for years of useful service when maintained
properly.
CAUTION:
Fully charge the unit before using for the first time. Damage
to the internal battery can result if the battery is in a fully discharged
state and operation of the unit is attempted.
A. Fully charge the unit before first use.
B. Store unit at room temperature if possible.
C. Always store the unit in a fully charged condition.
D. The battery will partially self-discharge over time. The rate of self-
discharge increases with temperature. It is recommended that the unit be
run for at least 2 hours every six months and then recharged overnight. This
will preserve the potential life of the internal battery to its fullest extent.
E. Do not leave the unit on charge for more than 24 hours. Unnecessary
extended charging will cause internal heating and potential premature
failure of the battery. The battery will fully charge in 8–12 hours from a fully
discharged state. Once the battery has reached full charge, the internal
battery charger/regulator circuit will place the battery in the trickle charge
mode to prevent overcharging.
