F76S Water Filters and MV876B

Automatic-Backwash Controls

APPLICATION

The F76S is a high flow capacity water filter used at

point-ofentry (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

backwash 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 11/4 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.

F76S WATER FILTERS AND MV876B AUTOMATIC-BACKWASH CONTROLS 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.

F76S WATER FILTERS AND MV876B AUTOMATIC-BACKWASH CONTROLS Commercial and Industrial Installations (1-1/2 and 2 in. models) F76S When installing an F76S, use the following procedure: 1. Shut off water supply by closing the water supply valve. 2. Install the F76S in the water line with the arrow pointing in the direction of water flow. 3. Install pressure gauge in the F76S center port (see Fig. 5). Commercial and industrial installations have high flow requirements.

Close the water supply valve to shut off water supply. Drain all water from the F76A by opening both a fixture downstream, and the backwash outlet; loosen the air vent on top of the F76A. Remove the backwash outlet (see Fig. 7): a. Grip the F76A fixture with a wrench. b.

F76S WATER FILTERS AND MV876B AUTOMATIC-BACKWASH CONTROLS 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. NOTE: 6. 7. Replace and tighten the four housing screws. Reconnect the power supply.

F76S WATER FILTERS AND MV876B AUTOMATIC-BACKWASH CONTROLS 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. WIRING CAUTION Electrical Shock or Equipment Damage Hazard. Water jets from the rapidly spinning impeller enhance the reversed water flow. The reverse flow removes trapped sediment and debris from the lower filter.
