CHECK FOR LEAKS
When a leak is suspected, first try to listen for leaks and/or spray with soapy water
around the connection ports. If a leak is found, isolate the area and relieve any
pressure on it prior to working on it. Fix the leaking part and return the system back
to operation. If no leak are heard (or visually seen with the soapy water), turn off
the unit and try isolating sections to see if there’s a pressure loss. If the BlastOff™
option is included with your unit, the system will alarm indicating that there is a
leak in the line. Consult with your installer if you cannot locate the leakage area.
