Description
The HL-CHEM is an ORP and pH sensing kit that is offered as an accessory for all OmniLogic®pool
automation controls. With the HL-CHEM, the OmniLogic can provide a fully integrated chemistry
solution for your pool. The HL-CHEM continuously tests the pool's sanitization and pH levels al-
lowing the OmniLogic to automatically generate the correct amount of chlorine and dispense the
proper amount of pH reducer. Together, they provide an automated system controlling both sanitiza-
tion and pH balance.
The HL-CHEM comes with two pigtails (120 VAC and 240 VAC) for connection to a pH reducing
device like a peristaltic pump or solenoid valve (not included) that requires a line cord receptacle.
For easy integration, Hayward offers the AQL-CHEM2 (120 VAC) and AQL-CHEM2-240 (240 VAC)
CO2dispense kit that plugs into the pigtail and will reduce the pool's pH level by injecting CO2into
the pool water.

What's Included
The HL-CHEM comes with everything needed to allow the OmniLogic to sense ORP and pH levels.
The following is a description of the included components:
Professional Grade ORP probe - Samples water from the pool filtration system and sends signals
to the OmniLogic indicating the oxidation-reduction potential (redox) of the pool water. ORP is an
actual measurement of sanitizer activity and bacteriological water quality rather than an expres-
sion of chemical residual levels. ORP is not fooled by the effects of pH, TDS (total dissolved solids)
and other factors giving a more accurate measurement of the effectiveness of chlorine and water
quality.
Professional Grade pH probe - Samples water from the pool filtration system and sends signals to
the OmniLogic indicating the acidity of the water. When used with a Hayward AQL-CHEM2 or other
pH dispensing device, the OmniLogic can keep the pool water's pH level balanced.
Probe Cell - The Probe Cell is used to house the probes and provide a location for water collection
and testing. Two hoses are provided to connect the Probe Cell to the supply and return sides of the
pool filtration system. The Probe Cell can be mounted directly to the OmniLogic or remote mounted
in the vicinity of the control (restricted by the length of the probe wiring).
pH Dispense Pigtails - The pH Dispense pigtails provide a plug-in receptacle for the AQL-CHEM2,
AQL-CHEM2-240 or other pH related dispensing device (peristaltic pumps, solenoid valves, etc.)
that will be controlled by the OmniLogic.
Various Hardware - The HL-CHEM includes the necessary tubing, tubing connectors and mounting
hardware to complete the installation.
Compatibility
The HL-CHEM is compatible with the OmniLogic pool control. An AQL-CL chemistry kit must be
used with the OmniLogic if automatic chlorine generation is desired.
Installation
DANGER of Death, Injury or Property Damage if procedure not followed. This accessory
connects to the OmniLogic panel beneath the dead front. Dead front removal is required for this
installation. Power to the OmniLogic panel MUST be shut off before the dead front is removed. This
means a complete shutdown of power to the entire OmniLogic panel

Before carrying out any part of the installation, you MUST power down the OmniLogic panel. If the
pool filter pump is not powered from the OmniLogic, it MUST be powered down separately. This
will relieve pressure in the pool filtration system.
Mounting the Probe Cell
The Probe Cell can be mounted directly on the side of the OmniLogic or mounted up to 15' away
(limited by length of Probe Cell cable). When mounting remotely, take into account the amount of
cable needed to route through the OmniLogic.
The key to successful Probe Cell installation is in the plumbing. A pressure differential is required
to allow clean, untreated water to pass through the cell and across the probes. Consider this when
looking for an ideal mounting location.
Side Mounting: Side mounting the HL-CHEM will require drilling 3 mounting holes through the
"dimples" found on the side of the OmniLogic enclosure. Refer to the diagram and steps below.
OmniLogic power must be shut off before the enclosure can be drilled.
1) Remove door and front panel.
2) Usea3/16"dia.drillbitanddrillthroughthethree"dimples"onthesideoftheenclosure.
Take care that any wires behind the enclosure wall are clear and will not be damaged by the
drill bit.
3) After the holes are drilled, grind or file down any burrs and brush away any metal chips.
4) Route Probe Cell cable through access hole at bottom of Probe Cell mounting bracket.
5) Use the included stainless steel hardware to fasten the HL-CHEM to the OmniLogic as shown
on the top of the following page.

USE ONLY HAYWARD GENUINE REPLACEMENT PARTS

Surface mounting: The Probe Cell can be mounted up to 15' away from the OmniLogic (limited by
length and routing of cable). Use the four mounting holes on the back of the bracket when surfac-
ing mounting. Common wood screws can be used for most applications.
Plumbing the Probe Cell to the pool plumbing
The Probe Cell requires connection to the pool plumbing using the supplied flex tubing. Two ports
on the Probe Cell, influent and effluent, are connected to the supply and return sides of the pool
plumbing. Refer to diagram on th following page as well as the instructions.

Cut a 3" length of flex tubing and insert it into the sample stream port. This port can be used to
draw water samples if needed.
If flex tubing needs to be replaced, use only 3/8” UV-resistant cross-linked polyethylene tubing
(PEX).
Installing ORP and pH probes to the Probe Cell
The ORP and pH probes are shipped "wet" in plastic storage caps. It's very important that the
probes remain wet at all times. If the probes are allowed to dry out, they will fail and the HL-CHEM
will be ineffective. After installation, the Probe Cell will ensure that the probes are constantly
exposed to pool water. During periods when the filter pump is off (even extended periods), there
should be sufficient moisture remaining in the Probe Cell to ensure that the probes are protected.
Remove the ORP and pH probes from their plastic storage caps and save the caps for future use.

At startup, check for leaks. If probe leaks, do not
tighten more—instead remove and re-apply new
Teflon tape.
Wiring the probes to the Probe Cell
Both probes must be wired to the communica-
tion box within the Probe Cell. The probe cables
use typical BNC connectors that attach to the
designated connectors on the communication box.
Refer to the label on the communication box for
the appropriate connections. Push the connectors
in and turn clockwise until locked. After connect-
ing, route the wires in a manner where they will
not interfere with the door of the Probe Cell. Save
BNC connector protective covers for future use.

Wiring the Pigtail or pH Dispensing Device
Two pigtails (120 VAC and 240 VAC) are included with the HL-CHEM sensing kit to be used with
pH dispensing devices (peristaltic pumps, solenoid valves, etc.) that require a plug-in receptacle,
including the Hayward AQL-CHEM2 and AQL-CHEM2-240. If your pH dispensing device will be
direct wired (hard wired), the pigtail is not necessary.
WARNING: Follow local codes for pigtail installation. Installation may require retrofitting a weather-
tight outlet and plug to the pigtail and dispense hardware (such as Cooper WaterTight or similar
connectors) or weather proof junction box.
NOTE: The OmniLogic can use either a 120 VAC or 240 VAC pH dispensing device. Wire the pigtail
or device directly to any of the OmniLogic relays. Provide the proper input voltage to the line side
of the relay. For 120 VAC, refer to the diagram below. For 240 VAC, refer to the diagram on page

ORP Control
A Hayward AQL-CL Chlorination Kit is needed if chlorine generation is desired.
If "Yes" is selected (AQL-CL Chlorination Kit must be used): You'll automatically be asked to config-
ure ORP settings as shown below. The OmniLogic refers to the ORP level in the pool and automati-
cally adjusts chlorine output to maintain the desired level.
If "No" is selected, and a AQL-CL Chlorination Kit is used: After answering "No", you'll be asked
ifaSaltWaterChlorineGeneratorwillbeused.Ifyouanswer"Yes"tothis,you'llbepromptedto
enter a run time %. The OmniLogic will generate chlorine for this % of time during the filter cycle.
Chlorine output is based on this manual setting only. ORP level is not used to control the chlorinator
output.

maintain the setpoint setting. Note that the OmniLogic will attempt to maintain this level but typi-
cally the pool's ORP level will vary above this value during normal operation. The adjustable range
is from 400mV to 900mV in 5mV increments.
ORP Timeout
To protect the pool, the OmniLogic control will automatically shut down ORP control and display an
alarm if the HL-CHEM runs continuously for more than the selected timeout value. This prevents a
situation where the OmniLogic is constantly feeding chlorine because of a probe error or external
problem with the pool. It allows the pool owner to evaluate the pool chemistry before continuing
with ORP control. Select the desired timeout value.

pH Timeout
To protect the pool, the OmniLogic control will automatically shut down pH control and display an
alarm if the HL-CHEM runs continuously for more than the selected timeout value. This prevents a
situation where the OmniLogic is constantly feeding acid or CO2because of a probe error or exter-
nal problem with the pool. It allows the pool owner to evaluate the pool chemistry before continu-
ing with pH control. The selectable range is 1-120 minutes.
pH Extend
When pH Extend is enabled, the OmniLogic control will keep the pool filter pump on regardless of
its timer settings until the pH level is within its programmed parameters. The pump will continue to
run and acid or CO2will continue to dispense until the programmed levels are reached. When the
pH level reaches the setpoint, the pump will be allowed to go back to automatic control.
Operation
Before operating the HL-CHEM, test and adjust the pool water chemistry to the recommended
levels shown in the OmniLogic Owner's Manuals. This is an important step and is crucial to the
successful operation of the HL-CHEM. If using salt chlorination, adjust salt to recommended levels.

Calib pH Calibration should take place at initial setup and periodically when the pH read-
out doesn't match tested values.
To calibrate the pH probe, test the pH of the pool water with a dependable qual-
ity test kit after the pool pump has been running for a period of time. Hayward
suggests that you take more than one test and average the results before using
the value to calibrate. Compare this result to the current pH reading and enter the
offset amount. If the tested value is lower than the current reading, the offset will be
negative. If greater, the offset will be positive. Refer to the example below.

Controlling pH with the OmniLogic
Plaster pools and pools serviced by salt-chlorine generators typically cause a slow pH rise which
must be managed. With the Sense and Dispense technology, CO2or acid is dispensed into the
filter system’s return water as needed until the pH probe reports proper pH level.
The Hayward AQL-CHEM2(-240) are CO2dispensing systems that eliminate the need to handle
acid and are economical and efficient methods for effective pH control. When the CO2gas is
injected into water, it dissolves and becomes carbonic acid, a weak acid that is very effective at
lowering pH but becomes self-limiting if over-fed.
CAUTION: IF YOU CHOOSE AN ACID FEEDER FOR pH CONTROL, additional safety precautions are
requiredtoensurethatanequipmentmalfunctionisdetected.Greatcaremustbetakenwhenin-
stalling, maintaining and operating acid pump feed systems. Acid is dangerous to handle, and will
harm people and equipment if not properly contained, transported, poured, stored, and dispensed.
CAUTION: Equipment failure can potentially cause too much acid to be dispensed into the water,
causing an equipment and health hazard which would not be detectable without the use of inde-
pendent pH measurement.

Maintenance
Water Chemistry
Always test water chemistry with a quality manual test kit. The HL-CHEM provides instrument
grade accuracy which exceeds that of most liquid-standard water testing kits. Therefore, it may be
preferable to calibrate pH using commercially available reference solutions. Calibrate pH periodi-
cally using the method described earlier in this manual. It's important to note that changes in pH,
cyanuric acid concentration, total dissolved solids, and use of additional or alternative sanitizers will
all affect the primary sanitizer residual level relative to ORP. Maintain total alkalinity on a regular
basis to ensure pH stability. To maintain a consistent sanitizer residual in parts per million (ppm),
periodically adjust the ORP level.
Probe Maintenance
The probes must be clean and free from oil, chemical deposits and contamination to function
properly. After saturation in pool or spa water, the probes may need to be cleaned on a weekly or
monthly basis depending on bather load and other pool specific characteristics. Slow response,
increased need to calibrate pH, and inconsistent readings are indications that the probes are in
need of cleaning.
To clean the probes without running the Wizard, turn off input power to the OmniLogic. Disconnect
the probe connectors from the communication box, unscrew the probe and carefully remove them
from the Probe Cell. Clean the reference junction (the white ring at the bottom of the probe body)
with a soft toothbrush and regular tooth paste. A household liquid dishwashing detergent may also
be used to remove any oil. Rinse with fresh water, replace teflon tape on threads and reinstall
probes. If properly cleaned probes continue to provide unstable readings or require excessive
calibration, the probes should be replaced.
Probe Storage
Exposure to atmospheric conditions will cause the probe tips to dry out. Store the probes with the
included plastic probe storage caps if removed from the Probe Cell for more than one hour. If the
storage caps have been misplaced, store the probes individually in small glass or plastic containers
with clean water covering the probe tips. Store probes in a location that will not be subjected to
freezing temperatures.
Winterizing
The HL-CHEM probes must be protected from freezing conditions. If the pool is winterized, plan to
remove and store the probes (as described above) as part of the normal pool winterizing process.
The Probe Cell and related plumbing must be drained as well. BNC connectors should be capped
with the original protective covers. A winterizing kit with probe caps, BNC covers, and other neces-
sary winterizing accessories is available to replace any missing items. Contact your local Hayward
dealer for more information.
