Performed an operation test on the Waterfurnace Legend unit to check for any out of specification measurements. Performed a heat of extraction worksheet to measure heating BTU output and efficiency. Heat of extraction shows that the system is outputting 31,525BTU/Hr. Waterfurnace specifications list the BTU/Hr output at 30F ground water temperature to be between 27,000 and 35,000 BTU/Hr. Compressor is running at 15A and is within specifications. Blower motor is running at 3A and is within specifications. Performed an operation test on emergency/auxiliary heating strips. Both heating strips are running at the proper 20A. Shut down heat stips to verify that the heat stips are not stuck on or shorted out. 0A reading when off. During operation test of geothermal, the only abnormal reading was the ground loop pressure. Ground loop pressure is currently at 20psi dormant. Ground loop pressure should be within 60-80PSI per Waterfurnace manufacturers recommended pressures. Low ground loop press
