INSTALLATION
Filter Plumbing
Make all plumbing connections in accordance with local
plumbing and building codes.
Before installing or operating the filter, remove the
temporary plugs from both the Pool and Pump ports in
the Backwash Valve Assembly.
Filter Location
1. Mount the FullFloXF
®
4000-Series D.E. Filter on
a level concrete slab. Position the filter to ensure
instructions, warnings and the pressure gauge are
visible to the operator.
Note:
Installation of anchor clamps is recommended
in high wind and seismically active areas. A Pentair
Anchor Clamp Kit (P/N 178840) can be purchased
separately. See page 4,
Anchor Clamp Installation,
for installation instructions.
2. Position the filter to ensure piping connections,
control valve and drain port are convenient and
accessible for servicing and winterizing.
3. Install all electrical controls at equipment pad, such
as on/off switches, timers, and control systems,
etc. to allow the operation and servicing of filter so
the user does not place any portion of his/her body
over or near the pump strainer lid, filter lid or valve
closures.
4. Allow sufficient clearance around the filter in order
to see that the clamp is properly installed around the
tank flanges. See
Figure 1
.
5. Allow sufficient space above the filter to remove the
filter lid for cleaning and servicing. This distance will
vary with the model of filter you are using. See
Table
1
for the required vertical clearance.
6. Position the filter to safely direct water drainage.
Rotate the HiFlow™ Manual Air Relief Valve to safely
direct purged air or water.
7. Install manual air relief valve onto the filter. See next
page for instructions.
8. Install backwash valve handle onto the filter. See
next page for instructions.

•
A separation tank is considered optional
equipment and must be purchased separately.
This filter must be installed by a qualified pool technician in accordance with all applicable local codes and ordinances.
Improper installation could result in death or serious injury to pool users, installers, servicers, or others and may also
cause damage to property.
For Installation of Electrical Controls at Equipment Pad (ON/OFF Switches, Timers, Control Systems and
Automation)
Install all electrical controls at the equipment pad, such as ON/OFF switches, timers, control systems, etc.
to allow the operation (startup, shutdown or servicing) of any pump or filter so the user does not place any portion of
his/her body over or near the pump strainer lid, filter lid or valve closures. This installation should allow the user enough
space to stand clear of the filter and pump strainer lid during system startup, shutdown or servicing of the system filter.
