Section 1. Important Safety Instructions
READ AND FOLLOW ALL INSTRUCTIONS
All electrical work must be performed by a licensed electrician and conform to all national, state, and local
codes. When installing and using this electrical equipment, basic safety precautions should always be
followed, including the following:
WARNING
Prolonged immersion in hot water may induce hyperthermia. Hyperthermia occurs when the internal temperature
of the body reaches a level several degrees above the normal body temperature of 37°C. The symptoms of
hyperthermia include dizziness, fainting, drowsiness, lethargy, and an increase in the internal temperature of the
body. The effects of hyperthermia include: 1) unawareness of impending danger; 2) failure to perceive heat; 3)
failure to recognize the need to exit spa; 4) physical inability to exit spa; 5) fetal damage in pregnant women; 6)
unconsciousness resulting in a danger of drowning.
DANGER
To reduce the risk of severe injury or death, do not remove the suction fittings of your spa or hot tub. Never operate
a spa or hot tub if the suction fittings are broken or missing. Never replace a suction fitting with one rated less than
the flow rate marked on the equipment assembly.
WARNING
To Reduce the Risk of Injury -
a) The water in a spa should never exceed 40°C. Water temperatures should remain between 38°C and 40°C.
The water in a spa should never exceed 40°C. Water temperatures between 38°C and 40°C are considered
safe for a healthy adult. Lower water temperatures are recommended for young children and when spa use
exceeds 10 minutes.
b) Since excessive water temperatures have a high potential for causing fetal damage during the early months of
pregnancy, pregnant or possibly pregnant women should limit spa water temperatures to 38°C. Before entering
a spa or hot tub, the user should measure the water temperature with an accurate thermometer since the
tolerance of water temperature-regulating devices varies.
d) The use of alcohol, drugs, or medication before or during spa or hot tub use may lead to unconsciousness with
the possibility of drowning.
e) Obese persons and persons with a history of heart disease, low or high blood pressure, circulatory system
problems, or diabetes should consult a physician before using a spa.
f) Persons using medication should consult a physician before using a spa or hot tub since some medication
may induce drowsiness while other medication may affect heart rate, blood pressure, and circulation.
WARNING
Risk of electric shock - Install the controller at least 3.5 metres from the inside wall of the pool and/or hot tub
using non-metallic plumbing.
Children should not use spas or hot tubs without adult supervision.
Do not use spas or hot tubs unless all suction guards are installed to prevent body and hair entrapment.
People using medications and/or having an adverse medical history should consult a physician before using a spa
or hot tub.
WARNING
To avoid injury ensure that you use this control system to control only packaged pool/spa heaters which have built-
in operating and high limit controls to limit water temperature for pool/spa applications. This device should not be
relied upon as a safety limit control.

SAVE THESE INSTRUCTIONS
WARNING
People with infectious diseases should not use a spa or hot tub.
To avoid injury, exercise care when entering or exiting the spa or hot tub.
Do not use drugs or alcohol before or during the use of a spa or hot tub to avoid unconsciousness and possible
drowning.
Before entering a spa or hot tub, measure the water temperature with an accurate thermometer.
Do not use a spa or hot tub immediately following strenuous exercise.
Prolonged immersion in a spa or hot tub may be injurious to your health.
Do not permit any electric appliance (such as a light, telephone, radio, or television) within 3.5 metres of a spa or
hot tub.
The use of alcohol, drugs or medication can greatly increase the risk of fatal hyperthermia in hot tubs and spas.
Water temperature in excess of 38°C may be hazardous to your health.
Attention Installer: Install to provide drainage of compartment for electrical components.
WARNING
A terminal bar marked "GROUND" is provided within the controller. To reduce the risk of electrical shock which can
cause serious injury or death, connect this terminal bar to the grounding terminal of your electric service or supply
panel with a continuous copper conductor having green insulation and one that is equivalent in size to the circuit
conductors supplying this equipment in accordance with AS/NZ 3000 - 2007. In addition, where required, bonding
should be extended in accordance with AS/NZ 3000 - 2007 to any metal ladders, water pipes, or other metal within
3.5 m of the pool/spa.

Section 3. Plumbing
The cell must be plumbed in a position that is
accessible for maintenance and within 2 meters of
the controller. The cell should be the last piece of
equipment in the circulation system. The cell must
be installed horizontally, levelandwithcorrectow
orientation, see Figure 3 and Figure 4.
1. If you intend to plumb the cell on a bypass,
the bypass must be equipped with Isolation
valves, see Figure 3 and Figure 4.
2. Plumb the cell inlet and outlet on vertical
lengths of 40 mm or 50 mm PVC pipe. The
cell inlet and outlet ports are 11.5 cm apart,
see Figure 2. The inlet of the cell is on the side
closest to the electrical lead, see Figure 5.
3. Put the unions onto the inlet and outlet pipes,
see Figure 5.
4. For 50 mm plumbing, glue the adapters
directly onto the pipes.
5. For 40 mm plumbing, glue the reducers into the
adapters then glue the adapters onto the pipes.
6. Ensure the o-rings are seated properly on the
adapters.
7. Secure the cell to the plumbing by
tightening the unions hand tight. DO NOT
OVERTIGHTEN.
8. Double check cell orientation. The cell inlet is
closest to the cell electrical lead.

pH Minus
CAUTION: Never store acid directly underneath any
equipment as fumes will cause corrosion and resulting
damage can void your warranty. It is recommended to store
your acid container in a safe, protected well ventilated area.
NOTE: The sensor POD must be positioned after
filtration and heating systems and before the cell.
Figure 4. Plumbing Cell and POD assembly
Figure 5. Cell Plumbing Assembly
WARNING
• The cell must be installed horizontally and level.
Improper installation can lead to gas build up which
could result in equipment damage or serious injury.
• The cell must be the last piece of equipment on
the return line, see Figure 3 and Figure 4.
• It is recommended in all installations that the cell is
installed on a bypass equipped with isolation valves,
see Figure 3 and Figure 4.
• In order to avoid load loss, installing the cell on a
bypass is MANDATORY if system flow rated exceeds
300 Lpm, see Figure 3 and Figure 4.
• If installing on a bypass, use a downstream check
valve instead of a manual valve to prevent improper
back flow into the cell.

Section 4. Install Controller
The controller should be located at or near the
equipment pad, at least 3.5 metres or more away
from the inside wall of the pool/spa, 1.5 metres
off the ground, and within 2 meters of the cell. All
national, state, and local codes are applicable.
4.1 Mount the Bracket
1. Determine the controller location.
2. Use the enclosed bracket to mark the
mounting surface through the screw holes.
3. Drill surface with 7 mm bit.
4. Install the included wall anchors.
5. Hang bracket using the included screws.
6. Hang the controller on the wall bracket and
slide to the right to secure in place.
Figure 6. Controller Mount
4.2 Install temperature sensor
The temperature sensor must be installed
upstream from any heating equipment, see Figure 3
and Figure 4. The sensor will need to be placed into
the plumbing system at any suitable position after
the filter pump and before any heating equipment.
1. Drill a Ø9 mm hole in the top of the pipe.
2. Ensure the o-ring is properly seated on the
sensor body.
3. Secure the sensor and o-ring with the screw
clamp provided. DO NOT OVERTIGHTEN.

WARNING
FOR YOUR SAFETY: This product must be
serviced by a professional pool/spa service
technician as described on the front cover of this
manual. The procedures in this manual must be
followed exactly. Failure to follow warning notices
and instructions may result in property damage,
serious injury, or death. Improper installation and/or
operation will void the warranty.
The controller must be permanently powered by
connection to a 30 mA residential circuit breaker.
The controller can be used to connect and control
multiple devices see Table 5 for a summary of functions.
4.3.1 Remove Lower Cover
1. Unplug power supply from mains.
2. Remove the external cover.
3. Remove the 2 screws from the lower housing.
