comes preset from the factory to backwash once every 24 hours of running time. For
every non-consecutive pin pull-out in a 24 hour cycle the filter will backwash. Each pin
represents 15 minutes of a 24-hour period. The filter can only backwash once every 1/2
hour by time clock. For every pin pulled-out consecutively, the filter will backwash once
and then lock itself out for 15 minutes multiplied by the number of pins pulled out. The 7-
day time clock is used to initiate the 2 minute backwash timer relay on any hour at any
specific time and day of the week. As an alternate, an optional 7-day timer is preset from
the factory to backwash once a week. The 7-day timer works the same as the 24-hour
clock except each pin represents 2 hours.
OPERATION AND MAINTENANCE
INITIAL AND SEASONAL START-UP
Before initial start-up or after a shut-down period, the PEP Industrial Water
Filter should be thoroughly inspected and cleaned. CAUTION: Perform the first five of the
following recommendations with the electric power off. Refer to the Safety Precautions
regarding the safeguarding of maintenance personnel from biological contaminants, prior
to Initial and Seasonal Start-Up.
1. Remove the bolts around the pump pre-strainer tank lid and remove the lid. Inspect
the O-ring seal and lubricate. Remove debris from the pump pre-strainer basket. Replace
the basket, lid and clamp (now is a good time to prime the pump suction line).
2. On manual systems only, rotate the valves manually by using the handle connecting the
valve linkage to ensure the valves operate smoothly. Upon initial start-up, make sure the
valves are in the backwash position and allow the filter to run for several minutes before
re-positioning the valves to the filter mode.
3. Loosen the access bolts around the vessel circumference, remove lid and lubricate the
bolts as necessary.
4. Inspect the over-drain assembly and media pack. If the media pack is contaminated,
remove the foreign material or replace the media. Replace the filter vessel top.
5. Open manual air relief valve on top of the filter tank. Start the pump motor briefly and
check the arrow on the pump volute for proper rotation. Turn the pump motor off. Do
NOT operate the pump for an extended period of time with the pump rotating backwards.
Have a qualified electrician change leads to correct rotation.
6. With the air relief valve open on top of the filter tank. Check the shut-off valves in the
