Start-Up

Check the reducer for lubricant.
shipped filled with oil. Before operating, the breather
plug must be installed in the top of the reducer (should
be placed in the uppermost side). See "Maintenance
Reducer" section.
Open reducer vent that has been plugged to prevent
lubricant loss during shipment.
Energize strainer motor and/or controls.
Open vent on strainer cover.
Slowly fill the strainer with fluid. Close strainer vent
when fluid begins to overflow the vent.
CAUTION:
The strainer must be filled with the working fluid
for operation to lubricate all bushings. Do not op-
erate strainer dry.
NOTE: Good operating practice dictates that the op-
erator observe the strainer carefully for several weeks
to determine the best operating mode, that is, continu-
ous or intermittent backwash. Refer to "Self-Cleaning
Strainer Control Panel Instructions" provided with
such equipment.

Operation

Operate the strainer in the continuous mode only,
unless controls for intermittent operation have been
provided and energized.
Normally the vent and drain valve are left in the closed
position. Approximately once each week, open the
drain valve for two to three minutes to remove any
settled debris on the strainer bottom. Note amount of
debris discharged. Frequency of this operation is de-
pendent upon the type and amount of trapped solids
in the liquid.
Take daily readings of the pressure drop across the
strainer to ensure proper operation.
CAUTION: Total pressure drop in excess of 10
psig is a warning signal requiring investigation
and corrective action.

If the differential pressure exceeds 10 psid:
Check strainer to verify rotation of the backwash arm.
If the shaft (visible at top of strainer) is rotating then
arm is rotating (refer to Trouble Shooting Section).
Check backwash line for restrictions. Valves in this
line should be opened fully, except for high pressure
or mesh screen applications in which case the back-
wash control and/or throttling valve should be adjusted
to a flow rate which produces thorough cleaning.
Position drain valve fully open for 2 to 3 minutes to
clear strainer of accumulated debris.
Increase the duration of the backwash cycle by adjust-
ing the timer in the control panel.
Should the pressure drop still remain above normal
with the backwash operating, close the outlet valve
and open the backwash valve fully for several min-
utes. If the pressure drop is not normal upon resum-
ing flow through the unit, the strainer should be shut-
down and internally examined.

Normal Shut-Down

Backwash the strainer for at least six minutes to clean
the strainer element.
Close the inlet/outlet flow valves. Then slowly open
the bottom drain valve and the vent on the strainer
cover.
De-energize strainer motor and/or controls.
Follow standard maintenance procedures contained
herein. Do not allow the straining elements to dry
while full of debris.

Emergency Shut-Down

To quickly shut-down the system, close the inlet and
outlet flow valves.
Fully open all vents and drains. Proceed with cau-
tion as the strainer may be under full pressure.
De-energize strainer motor and/or controls.
Follow standard maintenance procedures as soon as
possible.
