Quick Reference Guides are designed to provide assistance when diagnosing a geothermal heat pump. 

You will find attached a general troubleshooting guide not specific to any one unit.  The refrigerant pressures, superheat and subcooling are approximations. Though general, the information found on this sheet should help your technicians identify & diagnose systems more easily.  

Model specific guides provide actual test data for those models for more accurate diagnosis and repair of units in the field.

We recommend you print and laminate these pages for your technicians.
