F76S Water Filters and
MV876B Automatic-Backwash Controls
APPLICATION
The F76S is a high flow capacity water filter used at point-of-
entry (POE) to remove sediment and debris from residential or
commercial water systems. Used as a prefilter, the F76S
protects elements of the water system, including specialized
treatment devices such as taste/odor or reverse osmosis
(R/O) or other common fixtures and appliances. The flow,
filtering capacity, and ease of cleaning make the F76S the
ideal filter for the most demanding applications.
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 back-
wash function according to the desired interval.
FEATURES
F76
•
Built-in backwash impeller provides efficient cleaning
with supply pressures as low as 22 psi.
•
Increased flow capacity on 1/2 in. to 1-1/4 in. models
provides lower pressure drop.
•
Robust backwash mechanism.
•
No shut-off or disassembly is required for cleaning.
•
During backwash, the F76S continues to supply
filtered water without interruption through a secondary
screen.
•
Memory ring indicates when the next manual
backwash is due.
MV876
•
MV876B1018 bayonet fitting simplifies upgrade to
automatic backwash.
•
16 field-selectable backwash intervals (from every four
minutes to once every three months) on the MV876B
eliminate need for external timer.
•
Connections for external control on the MV876B
provide for use in automated systems and differential
pressure control.
•
MV876B can be turned manually to initiate backwash.
•
Battery (AA) backup to insure completion of backwash
cycle in spite of power loss.
