Water Underfloor Heating Pressure Testing
Before connecting the unit to the primary circuit it is recommended to pressure test the system.
This can best be achieved by connecting mains pressure hose to the red ball valve and a hose or
bucket to the blue ball valve on the control unit. Open both valves fully & fill the system to purge
all traces of air from the system.
After all the air has been removed it is recommended to pressure
test the system with 6 bar pressure for 24 hours. We recommend maintaining
the system under pressure whilst screeding.
Note
,
if there is a risk for the air temperature dropping below freezing, then you must protect the pipes
