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.
Contents
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.

F76S WATER FILTERS AND MV876B AUTOMATIC-BACKWASH CONTROLS
An increased pressure drop across the filter results when
PLANNING THE INSTALLATION
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.
The F76S should be sized based on the required flow rate and
the resulting pressure drop across the filter. As a guideline for
most applications, the F76S should be sized to avoid pressure
drops exceeding 3 psi.
EXAMPLE:What size F76S is required to provide a flow
NOTE: All filter installations are different. The size, type, and
amount of dirt and debris and the flow rate must

Commercial and Industrial Installations
(1-1/2 and 2 in. models)
IMPORTANT
When using an MV876, stop here and install the MV876.
Commercial and industrial installations have high flow
requirements. For proper operation, limit flow across the F76S
screen. For example, a two-inch pipe may have a 120 gpm flow
at 12 fps linear velocity across a clean screen. High linear
velocity impacts dirt deeply into the screen, making it difficult to
backwash and causing the screen to plug up quickly. In these
situations, install multiple F76 filters in parallel. See Fig. 3.

Ensure the F76S air vent is open.
Slowly open the water supply valve.
Once the F76S sump fills with water, close the air vent
and fully open the water supply valve.

Advantages of parallel installation:
•
•
Increased cleaning capacity. 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 interval. Because of the high flow
requirements, screens need cleaning on a regular basis. An
MV876 Automatic-Backwash Control can be installed to back-
wash the F76S automatically.

Set Pressure Gauge Needles
The black needle on the pressure gauge measures the F76S
outlet pressure. When the F76S is running with clean screens,
there is a small pressure drop across the F76S (3 psi at
maximum recommended flow).

Connect the hose fitting to the MV876 backwash outlet
(see Fig. 7).
The red needle is a stationary needle that helps monitor back-

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.

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 once every few weeks. Industrial applications
can require backwash several times a day. To determine the
backwash interval, see Determining Backwash Interval in the
Operation section.

Replace and tighten the four housing screws.
Reconnect the power supply.
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:

passing through the upper screen is directed through the
impeller to backwash the lower screen (from inside to out-
side). Remaining filtered water meets the needs downstream.
CAUTION
Water jets from the rapidly spinning impeller enhance the
reversed water flow. The reverse flow removes trapped
sediment and debris from the lower filter. This sediment drains
out the backwash outlet. Cleaning the lower screen requires
approximately 20 seconds. See Fig. 12b.

proper interval.
MV876
Determining Backwash Interval
1.
Mount the AT140A1034 Transformer and wire as shown
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.
2.
3.
4.
Ensure the F76 air vent is open.
Slowly open the water supply valve.
Once the F76 sump fills with water, close the air vent
EXAMPLE:In northern states, water usage is higher in
summer months than in winter months due to
lawn watering in the summer. Therefore, the
F76S should be backwashed more often in
and fully open the supply valve.
5.
Reconnect power to the system. When the system is
powered, the MV876 will run through one backwash
cycle (approximately 20 seconds).
summer months than in winter months.
By accurately determining a proper backwash interval, the
F76S will operate at a higher efficiency.
6.
7.
Set MV876 backwash interval to the desired setting.
See the Operation section.
Check MV876 operation by interrupting primary power
to the transformer. When power is switched back on, the
MV876 will backwash the F76 once.
To determine the F76S backwash interval:
1.
Backwash the system once to ensure the lower screen
is clean.
MV876
2.
The black pressure gauge needle measures outlet pressure.
With clean screens, inlet pressure equals outlet pressure
because of negligible pressure drop across the F76S.
Rotate the clear gauge cover to set the red needle to
match the black needle.
Record the date and time.
Monitor the F76S closely. Over time, the screens
become obstructed and outlet pressure drops.

7.
Record date and time again. Residential applications
can require an F76S backwash only once every few
weeks to once per week. Industrial applications can
require an F76S backwash several times a day.
Backwash the F76S regularly at the determined interval.
A backwash can be done manually or automatically.
a. Manual Backwash: Open the backwash outlet for
approximately 30 seconds.
OPERATION
The F76S Water Filter removes sediment and debris from the
water using an upper and lower screen. During normal
operation, no water passes through the upper screen. Water
With continued operation, the lower screen becomes
obstructed, reducing efficiency and creating a pressure drop
across the F76S. Backwash the F76S periodically. Suggested
interval is either once per week (residential applications) or
when the black needle measures about five psi lower than the
red needle.
NOTE: The amount of time required varies among
installations. However, 30 seconds is the
standard guideline to clean the lower screen.
b. Automatic Backwash: Install an MV876 Automatic-
Backwash Valve and select the backwash interval.
See the Operation section.
To backwash the F76S manually, open the backwash outlet
on the F76S bottom. This forces the entire filter insert down-
wards. Water flow to the lower screen outer side is blocked.
The upper filter removes sediment and debris from the water.
