Phased Plan For Adjustment - j.e. StorkAir MX 10/10 Bedienungsanleitung

9.3 Phased plan for adjustment

If the MX is intended for residential ventilation, use this table. Follow the marked directions from the top down in the column which is applicable.
Set the MX according to the table under §9.1.
Also set the calculated constant pressure.
Also set the calculated maximum pressure.
Set any external regulators to the highest position.
Close windows and doors.
Open all intake openings intended for that purpose.
Make sure there are constructional overflow facilities [min.12cm par ls]
Install the valves and set these according to the calculated settings chart.
Install the correct valves in the correct area.
Install the correct valves in the correct area. Close the two position valves
Install the extractor hoods and set the butterfly valves according to the
calculated settings chart. Close the extractor hoods.
Check the air volumes through the valves. Start as close as possible to
the fan.
Check the air volumes through the valves. Start as close as possible to
the place where the pressure is measured.
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.
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.
Adjust the required percentage 'Maximum capacity' if necessary. Refer to the
table. The lower the figure, the less energy used.
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].
Open the Extractor hoods.
Open the two position valves and the extractor hoods.
Check the air volumes through the valves again.
Check the underpressure behind the valve furthest from the fan. This
must be a minimum of 50Pa.
Check the air volumes through the valves and extractor hoods again.
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.
Draw up a measuring report.
Set any external regulators back to the correct position.
