jgraves Posted June 10, 2015 Report Share Posted June 10, 2015 I have ordered a Tecmark 3209 for my 1999 Master Spa LS650 and wanted to know if I need to change the setting on the pressure switch or should it be good to go out of the box? My spa has a 24-hour circulation pump if that makes a difference. Thanks! Jeff Quote Link to comment Share on other sites More sharing options...

jgraves Posted June 15, 2015 Author Report Share Posted June 15, 2015 Thanks! Under what circumstances would the pressure switch need adjusted? Quote Link to comment Share on other sites More sharing options...
PreservedSwine Posted June 15, 2015 Report Share Posted June 15, 2015 Only when it doesn't close under adequate pressure, or remains closed, when there is no pressure Quote Link to comment Share on other sites More sharing options...
