Section 3. In Line Installation (JEF-IN)
DO NOT INSTALL chlorine feeder before the heating system. Damage
to the heating system may occur.
In order to prevent risk of serious property damage, injury or death:
Wear eye and skin protection while maintaining or servicing this unit.
Do not inhale fumes from the chlorinator or chemical container.
Chlorine feeder may be under pressure. Use caution removing cover.
NOTE: Install a Check Valve before the Erosion Feeder to prevent the backow
of corrosive liquids and gases that may damage equipment.
1. Install the dosing unit down-stream of the heating system, if no heating
system is installed down-stream of the lter, see Figure 3(a).
NOTE: Ideally, the dosing unit should be installed above water level, but below
the lter outlet level, in order to avoid the gases being trapped when
the pump is shut down. If the unit has to be installed below the pool
water level, isolating ball valves MUST also be installed before and
after the dosing unit in order to allow future maintenance. We strongly
recommend the tting of a non-return valve to protect the equipment
room from chemical attack, should a situation arise where water
siphons back through the system.
2. Determine the desired location on a pipe segment at least 16 inches long.
The dosing unit cannot be mounted on a vertical, or sloping pipe.
3. Make the appropriate cuts in the pipe where you will be installing the cell.
4. Connect the unit to the pipework via the ½” union connections using PTFE
tape. Do not overtighten.
CAUTION
WARNING

Page 8
NOTE: In installations with a ow of greater than 50 g.p.m. (189.3 l.p.m),
install the unit on a by-pass to allow the correct adjustment of the
dosing rate and to avoid damage to the unit caused by excess ow.

Section 4. By-Pass Installation (JEF-OFF)
NOTE: There are two versions of the plumbing nipples included with this
feeder: one for use with 1 1/2” (50mm) PVC (Figure 4) and one for
2” (63mm) PVC.
1. Position the dosing unit on a level surface as close to the lter and
pump as possible. Do not install in copper plumbing.
2. The inlet connection must be made in the pipework between the pump
and lter. This connection will feed water into the dosing unit.
3. The outlet connection must be made down-stream of the heating
system or, if no heating system is installed, down-stream of the lter,
see Figure 4(a). This connection will be feeding treated water from the
dosing unit into the plumbing system.
4. Cut the dosing tube to the required lengths, ensuring the cuts are
clean, square and free of burrs.

5. Place the o-ring (5a) on the 1/4” check valve tting (5b) and thread
into the outlet side of the feeder. Do not over-tighten the tting.
6. Place the at rubber gasket (4x missing on diagram) onto the control
valve (5d). Place a small amount of teon tape (not included) onto the
valve threads.
7. Thread the control valve into the feeder on the inlet side. Do not over-
tighten.
8. Connect a section of the black tubing for the feeder inlet (5c) to the
hose barb on the control valve (5d).
9. Use one of the hose clamps (5f) to secure the tubing to the tting. Do
not over-tighten the hose clamp.
10. Connect a section of the black tubing for the feeder outlet (5e) to the
hose barb on the check valve (5b).
11. Use one of the hose clamps (5f) to secure the tubing to the tting. Do
not over-tighten the hose clamp.

12. INLET CONNECTION: Locate the inlet connection that you previously
determined to be the best place to provide untreated water to the feeder.
This will be the higher pressure connection for the system. Select an
orientation for the feeder nipple that will not interfere with any operation of
the pool, and will not be prone to breakage.
13. Drill a 3/8” (10mm) hole on one side of the pipe. TAKE CARE NOT TO
DRILL THROUGH THE OTHER SIDE OF THE PIPE.
14. Place a gasket on the pipe-side of the proper nipple and put the nipple
through the hole in the pipe clamp (Figure 6).
15. Tighten the pipe clamp down enough to compress the gasket but do not
over-tighten.
16. OUTLET CONNECTION: Locate the outlet connection that you previously
determined to be the best place to return treated water from feeder to the
pool return. This will be the lower pressure connection for the system.
Select an orientation for the feeder nipple that will not interfere with any
operation of the pool, and will not be prone to breakage.
17. Drill a 3/8” (10mm) hole on one side of the pipe. TAKE CARE NOT TO
DRILL THROUGH THE OTHER SIDE OF THE PIPE.

18. Place a gasket on the pipe-side of the proper nipple and put the nipple
through the hole in the pipe clamp (Figure 6).
19. Tighten the pipe clamp down enough to compress the gasket but do not
over-tighten.
20. Install the black feed tubes to the nipples with the hose clamps, paying
close attention to the inlet and outlet orientations. Ensure that the tubing
does not interfere with the maintenance of the pool equipment, and will not
be prone to being stepped on or otherwise disturbed.
21. Prior to adding chemicals, run the system and inspect hose connections
and seals to ensure there are no leaks.

In order to prevent risk of serious property damage, injury or death:
• Wear eye and skin protection while maintaining or servicing this unit.
• Do not inhale fumes from the chlorinator or chemical container.
• Chlorine feeder may be under pressure. Use caution removing cover.
Section 5. Operation
NOTE: The consumption of chlorine in swimming pools varies according to
use, temperature, exposure to sunlight, and other factors. Initially you
will need to experiment with the control valve to ensure that the unit
doses enough chemical to maintain the above residual. Start with the
valve in the middle position. Test the residual regularly and open the
valve a little more if the residual is not being reached or close a little
if it is being exceeded. Once desired level is reached, leave the valve
set in this position.
Elevated chemical concentrations and Hazardous Gas - The
introduction of potentially hazardous gas or elevated chemical
concentrations into the pool or spa during backwash and periods of
no ow in the circulation system can cause serious personal injury, or
death. To avoid, use the following guidelines:
• Set dosage indicator to zero before stopping water ow through the
chlorinator.
• Minimize backwash time.
• Do not shut o󰀨 pump for extended periods.
• Do not allow bathers into the pool or spa area until full ow through
the circulation system has been established.
