2. All PEP Industrial Water Filters should be rigidly anchored to the floor or support steel
by means of anchor bolts. The SMF-FG has holes suitable for 1/2" (13mm) anchor bolts.
3. After the unit is installed at a permanent location, the pressure gauge and air relief
valves should be installed on the top of the filter tank (some units will have vents already
installed). The sand media should be loaded into the filter at this time. Refer to loading
media section on the following page and Table 6.
PIPING
Piping to and from the PEP SMF-FG filter should be installed in accordance with the
drawing that was specifically furnished with the unit. In the event of a conflict between
subject drawing and labels on the filter piping, the drawing dictates and takes precedence
over the labels.
1. Connect the feed water line from the system sump or piping to the pump inlet. If the
inlet connection is located above the operating water level of the system sump, install a
foot/check valve to prevent loss of suction on the pump.
2. Connect the filtered water return line from the filter outlet to the system sump or
piping.
3. A service valve should be installed on the inlet, outlet, and city water line (if city water
is used) to allow servicing of the filter. For units using a backwash source other than the
system sump, refer to Table 3 to determine required backwash flow. Connect this line to
the "City Water" connection as shown in the drawing. The maximum city water backwash
supply pressure on the SMF filters should never exceed the pressure rating of the filter
vessel. If public or municipal water is used for backwash, a backflow prevention or check
valve is required in the line on all units (check standard local codes).
4. Connect a backwash waste line to the waste connection as shown in the drawing. This
line carries the backwash wastewater to the drain.
IMPORTANT: Do not put a valve in the waste line!
Refer to Table 3 for the minimum and maximum backwash flow rates. Note: If the drain is
not large enough to handle the volume of water during backwash, it may be necessary to
use a storage tank to collect the wastewater. A valve can be used to regulate the flow
from tank at a suitable rate to the drain. NEVER REDUCE THE SIZE OF WASTE WATER
LINE.
5. All interconnecting piping, fittings, valves, or other accessories connected to the filter
system (whether supplied by PEP or others) must be independently supported to eliminate
