INSTALLATION INSTRUCTIONS
TOOLS/SUPPLIES NEEDED: (Not Included)
For All Installations:
• Pipe cutter or hacksaw
• wrench
• screwdriver.
Optional:
• Round head screws to fasten the chlorinator to a base.
FOR IN-LINE INSTALLATIONS
(Model FPPA-9IL):
In-ground Pool:
• Teflon tape,
• (2) 1-1/2” threaded x 1-1/2” slip PVC bushings
• PVC cement.
NOTICE: Install a corrosion resistant check valve and fit-
ting to prevent chlorine from backing up and damaging
other system components.
INSTALLING IN-LINE CHLORINATOR
In-ground Pool Installation (See Figure 1)
1. The in-line chlorinator can be plumbed directly into a
1-1/2” plastic pipe downstream from all other equip-
ment. To avoid corrosion damage, DO NOT plumb
the chlorinator into copper pipe (see Figure 1).
2. Find a suitable location downstream from the filter
and heater (if installed). Always install the chlorinator
as far as possible from the heater (or other metal
equipment) to avoid chemical corrosion damage to
system components.
3. Install the chlorinator standing upright. If installed on
the ground, mount chlorinator on a treated wood slab
using round head screws through the mounting slots
in the base.
4. Brush pipe thread sealant onto the threads of both
1-1/2 x 1-1/2” face bushings. DO NOT use teflon
tape; it can cause leaks or bushing failure. Hand tight-
en the bushings into the chlorinator ports, then tighten
1 to 2 more complete turns with a wrench. DO NOT
overtighten. Overtightening will strain the joint and
can lead to joint/bushing failure.
5. Cement the PVC pipe into the bushings according to
the PVC cement manufacturer’s recommendations.
6. Isolate the chlorinator by installing a corrosion resistant
check valve or a plumbing loop (Hartford loop)
between the chlorinator and the rest of the pool equip-
ment. This will protect other system components (espe-
cially the heater) from chemical corrosion damage.
NOTICE: In case of high water flow (80 gpm or greater)
or if additional equipment (such as an in-floor cleaning
device) will be included on the pool installation, isolate
the chlorinator from the rest of the system through
plumbing loops (Hartford loops) and/or check valves as
recommended.
See your in-floor manufacturer’s recommended guidelines
for using an in-floor cleaning system with an automatic
chemical system. An installation other than that shown in
Figure 3 or those recommended by manufacturer of in-
floor cleaning system may result in over-chlorination
and/or damage to the chlorinator or the in-floor system.
Special Installation of In-line Chlorinator
1. Valve Bypass (Figure 2): For high flow applications (80
gpm or greater), use a 2 way ball valve to control
water flow to the chlorinator. A corrosion resistant
check valve is recommended.
2. Plumbing Loop (Figure 3): When installed with an in-
floor cleaning system, install the chlorinator in a
plumbing loop (gas trap) so that it is isolated from all
other equipment. To trap corrosive gasses and avoid
damage to other system components, make sure that
the piping both before and after the chlorinator is 3”
to 6” below the pool water level.
