RP-6 Pump for the GX-94 • 10
Allow the pump unit to sample for 90 seconds for a full
response on the GX-94.
If an optional hose and probe are used instead of the rubber
sample nipple, hold the pump unit in one hand while
holding the probe in the area to be sampled. To sample from
a well or other similar sample area, the hose and probe may
be lowered into the sample area. Allow the pump unit to
sample for 90 seconds for a full response on the GX-94.
NOTE: Although the RP-6 pump does have a hydrophobic
filter built in, the optional probe does not have a
hydrophobic filter. It has a dust filter only.

Low Flow Alarm
When pump unit experiences a low flow condition, the Low
Flow LED starts flashing and the pump stops operating. Check
the rubber sample nipple and filters to make sure they are clear.
If a hose and probe are used, check them for kinks or
obstructions. To reset the low flow condition, turn the pump
unit off and restart it. If the low flow condition persists, the
pump may need servicing.
