Observations made at the time of installation
W ooden Support should not be above FCU.
Supports should be at proper distance.
Strainer Valve should be properly aligned otherwise itwould not filter the CH W pipe line water which mightcause blockage in FCU.
Valve should be fitted inside the tray.
Tapping from main header line should have proper spaceto carry out the insulation work.
