F76S
(for F76A,G)
APPLICATION
The F76S is a high flow capacity water filter used at point-ofentry (POE) to remove sedime nt 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 backwash function according to the desired interval.
MV876
• MV876B1018 bayonet fitting simplifies upgrade to
automatic b ackwash.
• 16 field-selectable backw ash intervals (from every fo ur
minutes to once every three months) on the MV876B
eliminate need for ex ternal 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 c ompletio n of ba ckwash
cycle in spite of power loss.

PLANNING THE INSTALLATION
The F76S should be siz ed based on the requ ired flow rate and
the resulting pressure drop ac ros s the fi lte r. As a guideline for
most applications, the F76S should be size d to avoid pressu re
drops exceeding 3 psi.
EXAMPLE:What size F76S is required to provide a flow
rate of 30 gpm? Reading across Table 1 at
3 psi pressure drop, a 1 in. filter can provide 31
gpm without exceeding 3 psi pressure drop.
100
150

An increased pressure drop across the filter results when
higher velocities are maintained to increase the capacity
through any given size filter. Severe pressure drops will be
encountered as capacity approaches that of the pipe size. To
ensure the backwash cycle operates properly and cleaning
action is not reduced, follow all recommendations in Fig. 2.
Refer to Fig. 2a for an ideal installation.
NOTE: All filter installations are different. The size, type, and
amount of dirt and debris and the flow rate must
always be considered when choosing a screen and
deciding to install multiple F76 Water Filters in parallel.

F76S WATER FILTERS AND MV876B AUTOMATIC-BACKWASH CONTROLS
Commercial and Industrial Installations
(1-1/2 and 2 in. models)
Commercial and industrial installations have high flow
requirements. For proper operation, limit flow across the F76S
screen. For example, a two-inch pipe may hav e a 120 gpm flo w
at 12 fps linear velocity across a clean screen. High linear
velocity impacts dirt deeply in to the screen, maki ng it difficult to
backwash and causing the screen to plug up quickly. In these
situations, install multiple F76 filters in parallel. See Fig. 3.
3.
Install pressure gauge in the F76S center port (see Fig. 4).
IMPORTANT
When using an M V876, stop he re and insta ll the M V876.
4.
Ensure the F76S air vent is open.
5.
Slowly open the water supply valve.
6.
Once the F76S sump fills with water, close the air vent
and fully open the water supply valve.

Advantages of parallel installation:
• Increased cleaning ca pa cit y. Backwash interval is reduced.
• Elimination of system downtime. Can backwash one F76S
while the others maintain required flow.
Another consideration in commercial and industrial
installations is the backwash int erval. Becaus e of the high flo w
requirements, screens need cleaning on a regular basis. An
MV876 Automatic-Backwash Control can be installed to backwash the F76S automatically.

Set Pressure Gauge Needles
The black needle on the pressure gauge measures the F76S
outlet pressure. When the F76 S is running with clea n screens,
there is a small pressure drop across the F76S (3 psi at
maximum recommended flow).
The red needle is a stationary ne edle that helps monitor back wash interval.
NOTE: The following assumes a constant inlet pressure. If
inlet pressure is variable, another gauge on the inlet
piping, or the air vent will provide more information
regarding actual pressure differential.
1.
Backwash F76S once to ensure the screens are clean.
2.
With the F76S in operation, rotate the clear gauge co ver
to set the red needle to match the black needle.

M17352
As the F76S operates, screens become plugged. Backwash
the F76S when the black needle measures about five psi
lower than the red needle. However, each installation is
different. Residential applications can require backwash only
once a week, or o nce e very f ew wee ks. I ndustri al ap plica tions
can require backwash several times a day. To determine the
backwash interval, see Determining Backwash Interval in the
Operation section.
NOTE: For residential applications, backwash the F76S
once a week regardless of need is an excellent
guideline to follow to ensure F76S peak operating
efficiency.
Fitting Batteries and Fuses
The batteries (not included) provide power to the MV876 in
the event of a power loss. This is desirable especially when
power loss occurs during the reverse rinsing cycle. To provide
this, the MV876 requires four AA alkaline batteries. Install
these batteries in the cover of the MV876:

While the upper screen filters the water. Some of the water
passing through the upper screen is directed through the
impeller to backwash the lower screen (from inside to outside). Remaining filtered water meets the needs downstream.
Water jets from the rapidly spinning impeller enhance the
reversed water flow. The reverse flow removes trapped
sediment and debris from the low er filter . This se diment drains
out the backwash outlet. Cleaning the lower screen requires
approximately 20 seconds. See Fig. 12b.
The F76S requires no maintenance if backwashed at the
proper interval.
Determining Backwash Interval
All F76S applications are different and require backwashing at
different intervals. Backwash interval is directly proportional to:
— The level and type of sediment in the local water supply.
— Water usage.
EXAMPLE:In northern states, water usage is higher in
By accurately determining a proper backwash interval, the
F76S will operate at a higher efficiency.
To determine the F76S backwash interval:
1.
Backwash the system once to ensure the lower screen
is clean.
2.
The black pressure ga uge needl e measur es outlet pressure.
With clean screens, i nlet press ure equal s outlet p ressure

3.
Rotate the clear gauge cover to set the red needle to
match the black needle.
4.
Record the date and time.
5.
Monitor the F76S closely. Over time, the screens
become obstructed and outlet pressure drops.
NOTE: The F76S requires a backwash w hen the blac k
summer months than in winter months due to
lawn watering in the summer. Therefore, the
F76S should be backwashed more often in
summer months than in winter months.

Record date and time again. Residential applications
OPERATION
The F76S Wate r Filt er rem oves sed iment and debris from the
water using an upper and lower screen. During normal
operation, no water passes through the upper screen. Water
is filtered as it flows through the lower screen. (See Fig. 12a.)
With continued operation, the lower screen becomes
obstructed, reducing efficiency and creating a pressure drop
across the F76S. Back wash th e F76S p eriodic ally. Suggested
interval is either once per week (residential applications) or
when the black nee dle m easure s about fi ve ps i low er than the
red needle.
To backwash the F76S manually, open the backwash outlet
on the F76S bottom. This forces the entire filter insert downwards. Water flow to the lower screen outer side is blocked.
