XII. Maintenance
Sampler
a.
The Global Water WS750 Water Sampler requires minimal maintenance.
The sampler enclosure is rainproof and rugged. Avoid exposure to extremely
rough usage. Routinely wipe the carrying case and control panel face, rinse
the pickup hose and debris strainer, and wash the sample bottles with mild
soap and warm water. Additional plastic and glass sample bottles, neoprene
tubing for the sampler pump, bottle caps/float switches, removable debris
strainers, and pickup hose can be purchased from Global Water (see
Appendix C section).
Battery
b. If the pump runs slowly, this is an indication that the battery requires
recharging. Global Water recommends fully recharging batteries
approximately once per month. In addition, the battery should be recharged
before any extended use. NOTE: The battery life will last longer if recharged
before it drains below 10.5 volts.
c. To recharge the battery, disconnect the battery cable from the battery.
Remove the battery from the
enclosure. Attach the battery
charger’s spade lugs to the
battery terminals, red lug to red
terminal, and blue lug to black
terminal. Plug the charger into
a wall socket. A full recharge
will take about 12 hours.
Charging more than 24 hours
may shorten the battery life.
Additional batteries and battery
chargers are available from
Global Water (see Appendix C section).
