I. Introducon
A. Water Chemistry
Water chemistry is a complex science that contains many variables.
These variables not only aect the water environment itself, but
they can have adverse eects on your equipment as well as your
health. These are only some of the factors which we follow closely
to ensure the most healthy water interacons:
pH is the measurement of the acidity or basicity in an aqueous
soluon. A measurement below 7 is considered acid, while a
measurement above 7 is base or alkaline. It is a signicant factor
in determining the water quality as it aects sanizer levels, water
color, and human reacon to the water.
ORP (Oxidaon Reducon Potenal) is the measurement of the
oxidizing capacity present in water. ORP cannot be fooled by the
eects of pH, total dissolved solids (TDS), stabilizers, and non-
chlorine oxidizers. A typical ORP sensor measures Hypochlorous
Acid (HOCI), which is the more eecve component of free
chlorine. A higher ORP reading equates to the sanizer working
more eecvely.
Water balance is comprised of pH, calcium hardness, total
alkalinity, temperature, and TDS. When water is balanced, the
Langelier Saturaon Index is 0. Values above +0.3 lead to scaling
and cloudy water, while values below -0.3 can cause corrosion of
pool equipment and surfaces. If the water balance is not xed in
a mely manner, secondary eects can lead to rapidly declining
water condions that can aect the health of the water occupants.
pH and ORP work conversely to one another, and are aected by
other factors such as temperature, Cyanuric Acid, and TDS that can
increase the negave impacts of unbalanced water.

B. IMPORTANT SAFETY INSTRUCTIONS
1. READ AND FOLLOW ALL
INSTRUCTIONS.
2. Risk of electric shock: Connect the controller to a dedicated ground-
fault circuit interrupter (GFCI) circuit breaker.
a. A green colored terminal or a terminal marked G, GR, Ground,
Grounding, or the symbol* is located inside the supply
terminal box or compartment. To reduce the risk of electrical
shock, this terminal must be connected to the grounding means
provided in the electrical supply service panel with a connuous
copper wire equivalent in size to the circuit conductors
supplying this equipment.
*IEC Publicaon 417, Symbol 5019.
3. Disconnect power before servicing the controller.
4. Inspect all power cords frequently. Any damaged cords should be
replaced immediately to reduce the risk of injury by shock.
5. Always maintain a record of manual water chemistry readings using
an accurate test kit. Automated controllers are not a substute for
this Health Department requirement.
6. WARNING – To reduce the risk of injury, do not permit
children to use this product unless they are closely supervised at all
mes.
7. Danger – Risk of injury.
a. Replace damaged cord immediately.
b. Do not bury cord.
c. Connect to a grounded, grounding type receptacle only.
8. WARNING – Risk of electric shock. Install at least 5 feet
(1.5m) from inside wall of water enclosure using non-metallic
plumbing.
9. Operaon of this controller without a funconing ow-switch will
void the NSF Cercaon.
10. WARNING – Do not install this controller where it is
accessible to the public.
11. SAVE THESE INSTRUCTIONS.
C. System Components
1. IPS M820 pH/Dual ORP Controller
a. Allows automac monitoring of water sanizaon and pH
balance through a simple, user-friendly interface, resulng
in easier management of water balance in swimming
pools, spas, or circulang water environments.
b. Can be easily installed into your exisng pool environment
and equipment, or can be customized to your needs.
c. Monitors and displays the pH and ORP levels using LEDs
and digital readouts on the front panel. If the temperature
sensor is installed, the M820 will monitor temperature
and display on the front panel when in Temp mode.
Addionally, it will monitor up to two chemical tanks
equipped with level switches and displays status using LEDs
on the front panel.
There are six separate funcon buons allow simple
pushbuon control of these individual parameters:
1) Set Level – ORP or pH level to be maintained,
2) Dose Time – Timed or connuous feed modes,
3) Delay Time – Delay me between feed cycles,
4) Over Timer – Maximum feed cycles or me allowed,
5) High Alert – Maximum level of ORP or pH allowed,
6) Low Alert – Minimum level of ORP or pH allowed,
7) pH Cal – pH calibraon for variaon in pH sensors.
d. When the pH level rises above (acid feed) or falls below
(base feed) the set level, the controller will acvate the
chemical feeder for the set dose me. Then the set delay
me will occur. This dose and delay me will occur unl
the set level is reached.
e. When the ORP (sanizer) level reaches the set level, the
controller will acvate the chemical feeder for the set dose
me. Then the set delay me will occur. This dose and
delay me will occur unl the set level is reached.

2. Flow Cell with Flow Switch
a. An injecon-molded ow cell with integrated ow
switch houses the pH and ORP sensors, and partners with
the M820 controller to monitor the pH and ORP levels in
the water.
b. The ow switch veries that water is owing during a feed
cycle, and sends the controller instrucons to deacvate
the feed if water is not owing.
c. Operaon of this controller without a funconing ow-
switch will void the NSF Cercaon. Rounely check that
the ow-switch is funconing by closing the le valve on
the boom of the ow-cell (ow light should turn o).
3. pH and ORP Sensors
a. pH Sensor – standard (Use only IPS Controllers part # SXPH
to maintain NSF Cercaon)
b. ORP Planum Sensor – standard (Use only IPS Controllers
part # SXORP to maintain NSF Cercaon)
c. ORP Gold Sensor – for use with Salt Chlorine systems
(Use only IPS Controllers part # SXORP-G to maintain NSF
Cercaon)
4. Fings – tubing connectors (2) for tapping installaon of ow
cell input/output
5. In-line Filter with 2-way valves and mounng clamps (2)
6. Tubing – 25 feet of 3/8”
7. Mounng Board – ABS plasc with mounng holes and
stainless hardware (16” x 12” standard, 24” x 19” oponal for
mounng two chemical pumps)
8. Temperature Sensor – Senses the current water temperature
and displays the temperature in the display when in Temp
mode.
