F74C Reverse Rinsing Filter;

MV876 Automatic-Backwash Controls

APPLICATION

‘The F74C Reverse Rinsing Water Filters, used at

point-of-entry (POE) to remove sediment and debris from

residential or commercial water systems, ensure a continuous

supply of filtered water. The fine filter prevents the ingress of

foreign bodies, such as rust particles and grains of sand. Both

horizontal and vertical installations are possible. The flow,

filtering capacity and ease of cleaning make the F74C the

ideal filter for the most demanding applications. Both

horizontal and vertical installations are possible.

The MV876 Automatic-Backwash Control is available as an

accessory. This control is fitted to the drain valve and is

programmed by the user to automatically perform the

backwash function according to the desired interval.

FEATURES

F74C

• Built-in backwash impeller provides efficient cleaning

with supply pressures as low as 22 psi.

• Robust backwash mechanism.

• No shut-off or disassembly is required for cleaning.

• During backwash, the F74C continues to supply

filtered water without interruption through a secondary

screen.

• Memory ring indicates when the next manual

backwash is due.

• Bayonet connection enables simple retrofitting of

reverse rinse actuator.

• Can be installed on vertical or horizontal piping.

MV876B

• Bayonet fitting simplifies upgrade to automatic

backwash.

• 16 field-selectable backwash intervals (from every

four minutes to once every three months) eliminate

need for external timer.

• Connections for external control on the MV876 provide

for use in automated systems and differential pressure

control.

• MV876 can be manually activated to initiate backwash.

• Battery (AA) backup to insure completion of backwash

cycle in spite of power loss.
