⚠️ Safety Notice – Commercial Evaporative Cooling Products


This equipment must only be installed, commissioned, serviced and repaired by suitably qualified and licensed personnel.


Before commencing work, complete a task-specific risk assessment and ensure safe roof access, fall protection requirements, electrical isolation procedures, service clearances and appropriate PPE have been considered. All work must comply with applicable regulations, standards and manufacturer requirements.


Particular care must be taken when working at heights, in roof spaces, ceiling spaces and other restricted access areas. Additional consideration must be given to confined working conditions, electrical hazards, moving parts, water systems, wet surfaces, manual handling risks and weather conditions.


Do not proceed if safe access, weather conditions, required clearances, confined space risks or appropriate safety controls cannot be achieved and maintained.


Safety takes priority over diagnosis, repairs, installation schedules and customer expectations. If the task cannot be completed safely, it must not proceed until the risks have been adequately controlled.


Climate Wizard post-2020 manufactured control system using PLC interface 



Climate Wizards (CWH) incorporate a chlorinator that are designed to minimize bacterial levels within the coolers water tank


  • Chlorinator is active at all times the unit is operated in INDIRECT cooling mode, where the water level is above the bottom probe AND water conductivity is >1500µs/cm
  • Where water conductivity is <1500µs/cm for an extended period of time, a 24 hour tank drain cycle will commence
Its important the chlorinator is fitted and operating correctly and should be checked at each quarterly service

DO NOT OPERATE THE CHLORINATOR OUT OF WATER

Note: The PLC can display multiple faults, if present as you will see in the video PLC fault display toggles between FC 10 and 3


You can check if chlorinator is fitted/connected from the PLC monitor screen
