5. Now sensors could be connected to TRi control box unit. pH & ACL sensors
must then be calibrated before using TRi PRO module (see chapter 4 /
‘Calibrating pH & ACL sensors’).
WARNING:
Follow the colour code of sensor’s cables before plugging it onto TRi control
box unit :
- BNC socket marked « pH » = pH sensor’s cable (blue plug)
- BNC socket marked « ACL » = ACL sensor’s cable (red
plug) (3).
3.5/ Installing the fl ow switch
Flow switch is provided with TRi salt water chlorinator. It’s an important safety
device made for stopping chlorine generation if a ‘no fl ow’ situation occurs.
➤ 2 possibilities
:
a) TRi PRO module installed in the same time as TRi salt water
chlorinator
b) TRi PRO module installed on a pool already equipped with a TRi unit
a) TRi PRO module installed in the same time as TRi unit
1. Keep the fl ow switch from TRi salt water chlorinator.
2. Screw the fl ow switch in its dedicated threaded adaptor onto the POD (hand
tightening only !)
WARNING: An arrow on the top of the fl ow switch indicates water fl ow. It
must be perfectly parallel to the pipe on which the POD is positioned.
b) TRi PRO module installed on a pool already equipped with a TRi unit
When swimming pool already has a TRi salt water chlorinator, fl ow switch is
already fi tted onto a dedicated hose clamp near the TRi cell.
1. Remove the fl ow switch from its hose clamp by carefully unscrew its locking
ring (fi ltration off !).
2. Screw the fl ow switch in its dedicated threaded adaptor onto the POD (hand
tightening only !).
3. Fill the empty hole onto original fl ow switch’s hose clamp by using the
provided ½’’ threaded cap and Tefl on tape (parts #4 & #12).
Remark: It’s also possible to leave the fl ow switch in its original position on
the hose clamp. In this case, the threaded fl ow switch adaptor on the POD
should be removed to seal the hole with the provided threaded cap.
This possibility may be useful in order to ensure 100% safety (TRi cell
installed on a bypass with valves).

3.6/ Installing the pH minus injection line
IMPORTANT! Always use appropriate safety clothing when handling
chemical products (protection glasses, gloves and lab coat)
➤
Installing the injection pipe (peristaltic pump Ð one-way valve):
1. Cut an adequate length of hose from the supplied coil (part #7) to connect
the TRi PRO peristaltic pump to the one-way valve located onto the POD.
2. Remove the protective cover of TRi PRO peristaltic pump.
3. Fit the tube onto the threaded output connector on the pump as illustrated
in the picture below. The output of peristaltic pump is marked with an arrow
pointing downwards on the translucent blue casing (1).
4. Fit the other end of the pipe to the one-way valve located onto the POD (2).
POD overview with all its equipment (3):
Installing the intake pipe
(container → peristaltic pump):
1. Cut an adequate length of hose from the supplied coil
(part #7) to connect the pH minus container to the TRi
PRO peristaltic pump.
2. Fit the tube onto the threaded input connector on the
pump as illustrated in the picture below. The suction
inlet for the peristaltic pump is marked with an arrow
pointing up on the translucent blue casing (4).
3. Drill a hole of appropriate size to accommodate the
suction pipe in cap of the pH minus container and also
another smaller hole to prevent the container from
distorting (“air inlet”).
4. Pull the free extremity of the pipe through the hole drilled in the cap, then
place the ceramic weight as well as the nozzle (see picture below, parts #6
& #11) (5).
5. Ensure that ALL connections are safe and watertight before operating the
TRi PRO module.
6. Put the protection cover of the TRi PRO module peristaltic pump back into
place.
