Maintenance Guide

Please note that the information given below is only to act as a guide and the frequency of maintenance may depend

upon the unit’s age, usage and water quality.

Correct maintenance is vital to ensure optimum output and reliability.

All humidifiers will form part or your hot and cold water system and as such require you to undertake ceratin duties with

regards to “The control of Legionella bacteria in water systems”. Your water sampling / testing and disinfection regime

must be based on details in the O&M manual and from results of a site specific risk assessment.

For this type of Evaporative Humidifier, Neptronic recommend that disinfection is undertaken at least twice a year.
