2. Cleaning with the spray unit
If the "ultrasonic method" does not achieve lasting results because of strong contamination
of the evaporator, the evaporator must be cleaned with a spray lance and the "Seku-
Aircond" disinfectant.
Compared to the "ultrasonic method," the mechanical cleaning power for this method is
greater, as in this case a disinfectant is sprayed at high pressure.
The disinfectant to be used for this process (Seku-Aircond) is delivered as a 100%
concentrate in a 2-litre package.
However, it is used at a concentration of only 5%. That means: To make 1 litre of cleaning
agent, mix 50 ml of disinfectant with 950 ml of plain water. After spraying, the cleaning
agent must be allowed to work for 15 minutes. Then, rinse the evaporator with 1 litre of
plain water.
