Section 2. – Installation
The Chemflo is supplied with an installation guide. Installers should refer to this guide.
2.1 Plan the installation
Ensure that…
1. The Chemflo controller is installed in a sheltered location.
2. The Chemflo controller is close enough to the expected location of the Probe / Injection Tee
for the Probe cable and pump output tubing to reach without straining.
3. The maximum suction height from the bottom of the chemical drums to the dosing pumps is 2
metres.
4. The mains power lead from the pool pump reaches the Chemflo without straining.
5. The mains power lead from the Chemflo reaches a mains power outlet. If the controller is
mounted in a wet area, a weatherproof power outlet must be used. It is recommended that you
use an earth leakage circuit breaker with this power outlet. Please consult a qualified
electrician if you are not sure if this is fitted.
2.2 Install the Probe and Injection Tee
Install the Probe and Injection Tee as per the diagrams below. Use a suitable PVC joining
compound. The Tee is installed in the return line to the pool, as the pressure is low and the Probe
will only be exposed to clean, filtered water.
Section 2 – Installation
8
2.3 Fit Tubing into Chemical Drums
Insert the suction tubing
through the chemical
drum lid supplied and fit
the drum weight, as per
the diagram below. Be
sure to use the correct
type of chemical
resistant drum. Your pool
professional can advise
on this. For installations
where the lid provided is
not compatible with the
container, drill a 1/2” or
13mm hole into the lid of
the container and fit the
compression fitting. Drill
a second 2mm diameter
vent hole to avoid
suction build-up.
IMPORTANT INFORMATION REGARDING ACID
xAlways use dilute Hydrochloric Acid.
xAdd 5 Litres of Acid to 20 to 25 Litres of water.
xNEVER ADD WATER TO ACID
xUsing concentrated acid may damage your equipment and void the
warranty
2.4 Fit Tubing to Dosing Pumps
Insert the suction tubing
from the chemical drum
to the left hand side
compression fitting of the
dosing pump. Screw the
retaining nut into place
firmly, ensuring the tube
is securely anchored.
Repeat for the tubing on
the right hand side of the
pump.
Ensure that the
Chlorine drum is
connected to the
Chlorine pump, and the
Acid drum is
connected to the Acid
pump.

2.5 Mount Controller and Make Electrical Connections
Mount the Chemflo controller on a sturdy wall or post using minimum 3mm or 1/8” stainless steel
bolts, screws or masonry anchors.
The Chemflo controller MUST be installed in a sheltered location.
Connect the probe and pool pump to the Chemflo. Plug the Chemflo into a suitable power outlet.

2.6 Check Pool Size
The Chemflo is supplied pre-configured to suit pools of approximately 50,000 litre capacities.
If this does not suit your application the Chemflo can be re-configured for the following sizes:
Spa, 20,000 litres, 50,000 litres and 100,000 litres. To change pool size, please refer to section
9.2 .
The Pool Size set-up adjusts the Control Setup and the Emergency ShutOFF Timer to the ideal
values for that pool size. For more details on these topics, see sections 9.3 and 9.6.
2.7 Prime the Dosing Pumps
This step is optional, as the peristaltic dosing pumps are self priming and will operate correctly
when the Chemflo is switched on. The pump priming function has been included for those
installers who wish to check the operation of the dosing pumps when installation is complete.
1. Press .
2. Press until “oPrime Dosers” is selected and press .
3. Press or to select the Chlorine Pump, Acid Pump, or Both Pumps and press .
4. The Chemflo will now run the selected pump(s) for 3 minutes. This is enough time to suck the
chemical (or water) through the suction tube, through the pump and feed it through the output
tube…
Priming Dosers
for 3 mins 3:00
Note the countdown timer which is provided on the screen.
Press to quit pump priming.
5. The Chemflo will resume the normal pool pump cycle and dosing at the end of the 3 minutes.

Section 3. – Operating Instructions
3.1 Checking and Setting the ORP Set Point
1. Press .
2. Press until “oSet Points” is selected and press .
3. “oORP Set Point” is displayed, press .
4. Use the and keys to change the ORP Set Point.
5. Press to save the new ORP Set Point.
6. To quit without making or saving changes, simply press .
Notes
1. The Chemflo controls ORP within a 20 mV “control band”. If the Set Point is 700 mV, the
Chlorine pump will start when the reading drops to 680 mV and stop again when the reading
reaches 700 mV. The control band stops the pump being rapidly switched on and off when the
reading is close to the Set Point, thereby increasing the pump’s life.
2. The exact ORP Set Point to achieve the correct Chlorine level will vary depending on other
chemical factors such as pH, Alkalinity and Cyanuric Acid (stabiliser) levels.
It is imperative that the pool water is checked regularly to ensure that all other chemical
parameters are correct.
3. When first installing the Chemflo, check the Chlorine levels every few days using a Chlorine
test kit. Increase the ORP Set Point if the Chlorine level is low and decrease it if the Chlorine
level is high. Once the pool has been fine-tuned over a week or two, the controller will
accurately maintain the correct Chlorine level.
