XI. Maintenance
Sampler
The Global Water WS705 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 bottle 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 D section).
Battery
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 be maximized if recharged before it drains below 11
volts.
To recharge the battery, plug the included charger
into the charging jack on the outside on the sampler
enclosure. The WS705 has a 3-Stage charge
controller installed inside the battery enclosure that
will prevent over-charging. To prevent damage to the
battery and controller, use only the supplied charger.
Additional batteries and battery chargers are available
from Global Water (see Appendix D).
XII. Troubleshooting
a. Check that the battery is firmly connected to the control panel and confirm
that it is fully charged.
b. Press the Pump Test button on the front panel. The test button should
always run the pump, regardless of the state of any of the inputs.
c. Turn the power switch off for 1-2 seconds then back on to reset the sampler.
d. Check the Status LED on the front panel.
i. The LED is off: If the water sensors are being used, check the Rain
and Water Sensor inputs. Sensors must be in contact with moisture
and unused inputs must have one of the shorting plugs supplied with
the sampler plugged into the jack. If the Trigger Input is being used,
