2. Safety Instructions
WARNING Before commissioning or any change of operation, refer imperatively to
corresponding chapters of this manual!
2.1. Controllers use
HYDRO’pH®, HYDR’ORP®and HYDRO’pH/ORP®are used to measure and control the
pH and ORP potential by using specific sensors and suitable metering pumps under the options of
use described in this manual.
WARNING Any other use is considered non-compliant and must be outlawed.
SYCLOPE Electronique will not provide, in any way, the liability and
damages that could result.
2.2. User’s obligations
The user agrees to only let working with the equipment HYDRO’pH®, HYDR’ORP®and
HYDRO’pH/ORP®described in this manual the staff who:
is familiar with basic instructions on industrial safety and accident prevention,
is trained to use the device,
has read and understood these instructions, warnings and rules for handling.
The user is responsible for keeping this use and programming guide in a place close to the equipment,
reachable by any person designated as responsible and competent to handle such equipments
2.3. Risk prevention
WARNING: Installation and connection of the HYDRO’pH®, HYDR’ORP®and
HYDRO’pH/ORP®controllers must only be performed by skilled staff!
The installation must comply with safety current standards.
NOTE: The recyclable packaging of the HYDRO’pH®, HYDR’ORP®and
HYDRO’pH/ORP® must be eliminated under the current rules!
DANGER: Before connecting the power cable or manipulating metering pumps,
always CUT THE PRIMARY POWER SUPPLY!
Do not open the device when power is on!
The maintenance and repair should be performed only by authorized
and skilled staff!
DANGER: HYDRO’pH®, HYDR’ORP® and HYDRO’pH/ORP®controllers must be

Page : 8
________________________________________________________________________________________________
HYDRO’pH®, HYDR’ORP®and HYDRO’pH/ORP®instructions
CAUTION: Carefully choose the installation site of equipments!
HYDRO’pH®, HYDR’ORP® and HYDRO’pH/ORP®controllers should
not be installed in a risky place, for instance close to water sprays or
chemical products. They must be installed in a dry and well-ventilated
place away from corrosive fumes.
They should not be exposed to direct sunlight.
They should not be installed outside without being protected from bad
weather. (Rain, hail, wind...)
They should not be installed under cover directly exposed to the sun's
heat so as not to exceed the maximum service temperature.
They must be protected from freezing. (See section wintering)
If potential winter, these devices must be disassembled and placed in a
dry place, protected from freezing.
Measurement sensors must be maintained and preserved with their
conservation cap filled with preservation fluid. (See sensor
instructions attached)
CAUTION: Before the commissioning of the equipment, make sure that all
electrical parameters are correct! Make sure the voltage of the device
corresponds to that indicated on the descriptive plate located on the
side of the controller.
WARNING: The maximum allowable pressure at injection points of chemical
products must not exceed 1.5 bar!
If these instructions are not complied, serious damage to
persons and / or the device may occur. Our guarantee or our
liability cannot therefore be committed.

4Installation and connections
4-1 Transport and storage of HYDRO’pH®, HYDR’ORP®and HYDRO’pH/ORP®
HYDRO’pH®, HYDR’ORP®and HYDRO’pH/ORP®controllers are high-tech electronic devices
that use electronic components and sensitive electrochemical sensors.
Despite the care taken in the design on the strength and robustness of the components used, make all
arrangements for transport and storage equipment.
NOTE: Equipment storage in a dry place.
After unpacking, proceed to the assembly as quick as possible.
CAUTION: Transport equipment with caution!
Do not shock! Protect pH and ORP sensors from shocks, concentrated
chemicals and ensure of permanent humidification of measurement
tips.
NOTE: The recyclable packaging of HYDRO’pH®, HYDR’ORP®and
HYDRO’pH/ORP®devices must be eliminated according to the current
rules!
Keep wintering packaging!
RECYCLING: Electronic equipments shall be brought back to your retailer so he can
proceed to their elimination respecting the current rules!
Keep wintering packaging!
4-2 Wall mounting terms
Dry and dusted place
Operating ambient temperature between 0°C and 45°C
Installation location out of vibrations
Clean, non-distorted support
Correct wall fixing
CAUTION: Respect mounting instructions. In case of non-compliance:
●The unit may be damaged
●Measurements may be disturbed
●The warranty will not be insured!
4-3 Wall installation of control device
DANGER: Prior to installing the devices and connections of cables, pipes and
fittings, cut power supplies!
The IP65 protection class is guaranteed only if the closure caps of the
Hydro’… electronic controllers are closed and the wires correspond to
the diameter of the cable gland!
Page : 15
________________________________________________________________________________________________
HYDRO’pH®, HYDR’ORP®and HYDRO’pH/ORP®instructions
Mounting procedure of HYDRO’… boxes
1. Cut general power supply
2. Make sure the filtration pump power is off.
3. Close the valves of the hydraulic system and put the filter valve on « Off »
4. Drill 4 holes of Ø 8mm according to previous plan using or not the fixation kit provided
for this purpose. (If mounting without kit the drilling dimensions are different!)
5. Insert 8 mm raw plugs with a hammer.
6. Attach the bottom screws and tighten moderately, leaving a space between the screw head
and the wall.
7. Hang the electronic box and leave a minimum clearance with the wall.
8. Fix the upper screws and tighten the lower screws once in place.
9. For a fixation without kit, open the top door of the electronic box and tighten the 4 screws
starting with the two top screws. (Beware to internal electric cables!)
10. Fix the 2 lower screws through the appropriate holes.
11. Close the door once the operation ended.
CAUTION: When closing the protection cover, take care not to damage the gasket
or pull the cables between the cover and the electronic card!
4-4 Installation of pipe saddles for sensors and products injection
CAUTION: The installation of the pipe saddles depends on your pool and the
necessary space available!
Different situations may arise:
