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.
