This video from Delphi shows the procedure for repairing an all-aluminum microchannel air coil in the field or shop.
While it does not happen often, sometimes coax fail. In today’s video we’re going to discuss testing a geothermal water / refrigerant coax for a leak. Every precaution should be taken to properly diagnose a suspected failed coax. In this video, we’ll provide testing procedures and recommendations to help you diagnose a leak. When we investigate a failed coax, there are three reasons for failure. The first – which is very rare – is a manufacturing defect. The second reason for failure...
Welcome to Geothermal University. One of the most critical installation procedure is flushing, purging, filtering the loop before startup. The top cause of pump failure is water quality, air and debris. This video will discuss the importance of water evaluation, filtering, removing debris and adding antifreeze. Thanks for watching!
If and when an ECM motor fails, the customer need not be without heating or cooling. By temporarily installing a PSC motor and capacitor you can provide heat or cool until the replacement ECM motor arrives. Be sure to download the accompanying file at Geothermal University.
