Section 5: System Troubleshooting
The Geotech High Vacuum Sampler has been designed and manufactured to provide a
long service life and trouble free operation in the field. If the compressor (vacuum)
becomes sluggish then check the supply voltage. If the supply voltage falls below 12 VDC,
the compressor’s performance will be directly affected. A fully charged battery will produce
the best results.
Other sources of low vacuum may be attributed to 12V lighter receptacles or plug
connections. Make certain these connections are securely plugged in and clear of any
debris. Once securely plugged in, rotating the connection can often help if there is a dead
spot in the connector. Also, check for connection and cable fatigue, cracks, surface
oxidation, rust etc.
Troubleshooting Procedures
Problem:
Compressor does not turn on
Solutions:
• Double check battery polarity is correct. In other words, the positive and negative
cables are connected positive to positive and negative to negative. The High Vacuum
Sampler is protected from damage due to reverse polarity connection.
• If ambient temperatures are in excess of 104°F (~40°C) then disconnect from power
and let sit in a cool location. Do not open the case for any reason. This will not hasten
the cooling process, but will invite debris into internal components that could result in
reduced life or immediate equipment failure.
• If the compressor still does not turn on then call Geotech Service at 1-800-833-7958
to arrange for the equipment to be sent back to a factory authorized repair location.
• If the 15 Amp circuit breaker is tripped, push to reset. If it trips again, call Geotech
Service at 1-800-833-7958 to arrange for the equipment to be sent back to a factory
authorized repair location.
Problem:
Compressor turns on but there is no air flow to the sample bag
Solutions:
• Remove the air line from the AIR OUT port. Turn on the unit and block the AIR OUT
port with your thumb. If there is pressure against your thumb then check the tubing for
cuts, kinks and holes.
• Verify that the sample bag has not been cut or perforated.
