Servicing and Maintenance
This humidifier must be installed, operated, and maintained by suitably qualified personnel and in
accordance with this manual.
Preventative Maintenance
The SKV Evaporative Cooling Humidifier requires both inspection and service at regular intervals. The frequency of
servicing depends on factors such as water quality, capacity and the number of hours in operation. It is recommended to
inspect and service the evaporation module after 200 hours post commissioning. This inspection is necessary to
determine the frequency of both inspection and service.
Verification List
Perform the following activities regularly to ensure optimal performance and operation of the evaporative module(s).
Check for water leaks.
Check for stagnant water.
Observe the operation of the water flow and evaporation cycle.
Check drain operation and flow.
Ensure that all electrical connections are secure.
Ensure that the 5µ water PP pre-filter is not clogged.
Verify if the Silver Ion “service warning” has appeared. If so, replace the Silver Ion dosing cartridge
Ensure that the air duct filter upstream of the SKV evaporation module is clean.

Maintain a clean, drinking quality water supply.
Avoid
water
stagnation.
Carry out regular microbiological testing of water (counting the number of bacterial units).
Refer to the ISO 5667-1 standard (Water quality - Sampling - Part 1: Guidelines for the design of programs
and sampling techniques)
Clean and disinfect the system regularly. Refer to Legionella and the prevention of legionellosis, by World
Health Organization 2007, ISBN 92 4 156297 8 for more detailed advice on control measures.
