This document is Geocontrol PRO Installation and Operation Manual, which mainly introduces the description, installation, operation, maintenance, troubleshooting, specifications, replacement parts list, EC declaration and warranty of Geocontrol PRO system.
The Geotech Geocontrol PRO is a unique controller designed for operating down well bladder type sampling pumps. When connected to an external 12 VDC power source, its internal air compressor produces pressure up to 100 PSI (7 bar), allowing users to take samples from depths up to 180 feet (55 meters). The controller features a variable cycle timer to manage the compressor's ON and OFF times, optimizing the pumping process by compressing the internal bladder to evacuate liquid and then allowing it to refill.
The document covers system installation, including wiring to a negatively grounded 12V system, and detailed operation instructions for adjusting the FILL TIME and DISCHARGE TIME knobs based on water depth. It also outlines maintenance procedures, emphasizing that repairs must be performed by factory-trained technicians, and provides a troubleshooting guide for common issues such as compressor failure or lack of pressure indication.

The controller allows the user to take samples from a depth of up to 180 feet (55 meters).
The controller must be wired to a negatively grounded system with a 12 VDC power source.
No, the unit must be returned to Geotech Environmental Equipment for any service, as improper repair may degrade performance.
Check battery polarity, let the unit sit in the OFF state for two minutes to hard reset the timer, or check for tripped circuit breakers.
