The following additional instructions must be read when using Apex Lite Pump
versions.
WARNINGS !
Apex Lite Versions are not intrinsically safe and must not be used in Hazardous Zoned
areas.
Batteries and charging:
Apex Lite versions operate from 4 x AA
dry cell batteries, so no charger is required.
AA sized NimH rechargeable cells can also
be used in the holder if preferred but no
charging will take place if the units are
placed in the Apex charger base
(182052B).
To convert the Lite version to a
rechargeable version purchase the
rechargeable battery pack 182073B insert
in place of the dry cell battery pack and
place in charger base 182052B.
Do not insert pump using dry cells into any recharging base.
