Original parts, and qualified servicing are provided through our dealer network. Original parts are also available in our Webshop.
Mechanical parts, such as feed hoses have to be changed yearly. Parts in contact with chemicals, such as dosing lines, and injection valves should be controlled annually, and changed every two years at latest. Sensors have a typical live of approximately 2 years, however, depending on the water hardness situation, of what is delivered from your local water supplier, life can be anything from about 6 months to 4 years.
No tools are necessary to service CNI Chemodata Systems.
Original CNI Chemodata sensors are equipped with stabiliser salt rings in the glass body, so that the electrolyte has always the same characteristics for the sensor life. Calibration is necessary when new sensors are connected to a system, or at season start, or once a year only. When all salt rings are used up, no more salt rings are visible, the sensors are then at end of life, and have to be replaced. Do not forget to order calibration liquids with new sensors.
The pH value should be set, and run in the range of about pH 7.2 topH 7.4 typically. Only if the pH value is stable and in the good range, the disinfection will run well, and stable as well.
ORP (Redox) is the oxidation, therefore the activity of disinfection in the pool water. ORP is typically rised by use of chlorine (and, or ozone). ORP is always dependent on how much chlorine (and, or ozone) is in the water, but is also dependent on the actual pH value. With a given quantity of chlorine in the water, ORP levels are higher, activity of chlorine therefore is stronger, when pH values are closer to pH 7, while with the same quantity of chlorine, activity, so ORP is lower on higher pH levels direction pH 7.6 or higher.
Free chlorine is the quantity of chlorine which is stored in the pool water, currently not used for disinfection (overstock), while ORP is the oxidation of the chlorine’s (and, or ozone’s) disinfection activity (working). CNI Chemodata Systems are able to calculate the free chlorine levels approximately if the measured pH values, and ORP values are in certain ranges to each other.
Check if sensors are within life time (salt rings visible in glass body). Check if connector contact to sensor is good and dry. Check if sensor is correctly calibrated at pH7, and pH9. Check age of indicator liquids, or tablets in your hand measuring equipment.
Check if sensors are within life time (salt rings visible in glass body). Check if connector contact to sensor is good and dry. Check if sensor is correctly calibrated at +465mV. Check age of indicator liquids, or tablets in your hand measuring equipment.
Dosing Problems can be based on mechanical, or electronic issues. First check, that all Hose connections are connected so that they do not pull air. Liquid is visible in dosing lines to check if mechanical connections are ok. On the electronic side, check, that settings of dosing logics, such as Microsdosing dose time, wait time, ans max feed timer are set correctly for your pool size. You can use the pool size selector in the main menu set to SPA for up to 10 m3, set to SMALL for 10 to 30 m3, set to MEDIUM for 30 to 70 m3, and set to LARGE for 70 m3, and larger pools. All microdose settings will be preset then automatically, however at some hydraulic situations in pools, some detail adjustments are sometimes required to adapt perfectly.
Like with a car, where you ask your car dealer for repairs, and support, please contact your local dealer. If you want assistance from the manufacturer, please fill out the form below in our support section. Always fill out the form with as much information as possible, so that we can help you efficiently. We do not provide phone assistance.
