xxxxSet any external regulators back to the correct position.
xxxxxDraw up a measuring report.

Check the air volumes through the extractor hoods Check the under-
pressure behind the valve furthest from the fan. This must be a
minimum of 50Pa.
xxCheck the air volumes through the valves and extractor hoods again.
x
Check the underpressure behind the valve furthest from the fan. This
must be a minimum of 50Pa.
xxCheck the air volumes through the valves again.
xOpen the two position valves and the extractor hoods.
xxOpen the Extractor hoods.
xxxx
Adjust the required pressure ‘Set point digital [1]’ if necessary. Refer to the
table. The lower the figure, the less inergy used. Also adjust the ‘Set point
digital [0]’ 50% of ‘Set point digital [1].
xx
Adjust the required percentage ‘Maximum capacity’ if necessary. Refer to the
table. The lower the figure, the less energy used.
xxxx
If the majority of the deviations is minus [or plus], ensure that all the
deviations are minus [or plus]. Also ensure that the most unfavourable
valve is completely open.
xx
Check the underpressure behind the valve furthest from the fan. This
must ba a minimum of 50PA. Check the underpressure behind the valve
closest to the fan. This must be a maximum of 200Pa. Arrange for extra
resistance in the branch if necessary.
xx
Check the air volumes through the valves. Start as close as possible to
the place where the pressure is measured.

Check the air volumes through the valves. Start as close as possible to
the fan.

Install the extractor hoods and set the butterfly valves according to the
calculated settings chart. Close the extractor hoods.
xInstall the correct valves in the correct area. Close the two position valves
xInstall the correct valves in the correct area.
xxxxInstall the valves and set these according to the calculated settings chart.
xxxxxxMake sure there are constructional overflow facilities [min.12cm par ls]
xxxxxxOpen all intake openings intended for that purpose.
xxxxxxClose windows and doors.
xxxxxxSet any external regulators to the highest position.
xxAlso set the calculated maximum pressure.
xxxxAlso set the calculated constant pressure.
xxxxxxSet the MX according to the table under §9.1.
