ACTUATOR REQUIREMENTS
PEP SMF-FG filters utilize electric actuators to control the valve action between the filtration
and backwash modes. The electric actuator is designed for 110 VAC control.
LOADING THE FILTER MEDIA
The special spherical silica sand media used in all PEP Industrial Water Filters is designed
to remove over 95% (by volume/weight) of all suspended solids. The media will ship to
the jobsite in 0.5 ft 3 (14,160 cu. cm.) drums @ 50 lb./drum or in 1 ft 3 (28,320 cu. cm.)
bags @ 100 lbs./bag for easy handling during the media loading process.
1. NEVER LOAD MEDIA INTO A DRY FILTER TANK, fill tank one-third to one half full with
water before loading. Always check filter internals before loading media. This procedure is
the same for Unigran 55 and 85. Refer to Table 6 for appropriate media quantities for a
specific filter size.
WIRING
PEP Industrial Water Filters supplied with a pump and automatic backwash controls are
provided with the following as standard: UL Type 4X control cabinet containing an on/off
disconnect switch, motor overload protection, transformer to provide 110v control voltage,
backwash timer, 24 hour time clock, pressure differential switch to initiate backwash, valve
actuator to reposition valves for backwash, and push button for manual backwash
initiation. Units are provided with the customer requested voltage/phase (460 volt, three
phase standard). Check the current draw upon initial start-up and make sure that it is

starter. Units supplied as manual are provided with no motor control of any kind.
