Installation of manometers for constant flow and constant pressure
When installing the accessory mechanically and connecting its electronics please follow the guide
enclosed to this optional accessory.
2.14.
Installation of liquid manometers
1. If the appliance is supplied without liquid manometers for measuring the pressure difference of air
filters, place each manometer on a suitable vertical surface near the pressure measurement points
(the maximum length of connecting hoses is 1 meter). Suitable location is indicated in the
production by a sunk slot where drilling can begin. Make sure that the location of manometers
enables regular inspection of values to be measured. Level manometers horizontally and secure
them with self-tapping screws provided.
2. Connect monometers using hoses with the pressure measurement points on the casing of the
appliance. Connect the hose on the top of the manometer and lead it to the plastic bushing on the
casing of the appliance. The hose must always connect two connection points marked identically
by "+" or "-" (must not be swapped). Make sure that hoses from only one filter are connected to
each single manometer!
3. Stick a relevant label supplied together with accompanying documentation near each manometer.
The label contains information about each air filter. Make sure that the location of the label
enables regular inspection of values to be measured.
4. Fully unscrew the rotation knob for setting zero on the scale (bottom knob marked "+") and then
screw it approximately two full turns back to allow for setting in both directions.
5. Unscrew the "FILL" plug (top knob) and start filling the appliance with measurement fluid (part of
delivery) until you can see the fluid near zero on the scale. Use the bottom knob to accurately set
the zero value on the scale. Screw the top filling plug back.
After connecting manometers do not tilt the appliance or door (if manometers are located there)!
Danger of measurement fluid leakage.
