Graf MINIMAX Notice D'installation Et D'entretien page 18

In the case of normal rainfall of 150 l/s, the amount of water to be harvested from a roof area of 150 m² is
approximately 2.25 l/s, that is equal to 135 l/min.
The MINIMAX-Filter has with this flow volume an efficiency factor of 99%, this means in real terms that a
tank with a volume of 4000 l will be filled in approximately 30 minuets.
The brass jet ¾" is to be inserted in the provided aperture at the inlet side of the filter housing and fixed
with the brass bend from the outside. Afterwards the brass hose nozzle is to be screwed on with a union
nut and connected with the hose (provided by customer). The hose is conducted through the empty
conduit to the pump and linked with the pressure line on the pressure side after a cut-off cock.
