Programmed Maintenance
Programmed maintenance means that a scheduled shut down will need to be planned for all cooling equipment once every three months for approximately 4 hours and one every six months for 8 hours. This may vary depending on tower size and location. This schedule has been designed to comply with the requirements of AS3666 Part 2 Operation and Maintenance. Only suitably trained personnel are authorised to carry out these works. This schedule does not cover the application of chemicals into the system for microbial control. A specialist water treatment company should be engaged to carry this out.
Recommended maintenance schedule for Evaporative Cooling Equipment over a 12 month period.
