9. Cleaning
9.1. Air filter mat
To maintain high performance capability the optionally available air filter mat ( Chapter 3.24 Air
filter mat ) must be checked for dirt at least once a month. Suitable air filter mats can be ordered
as original spare parts at any time – please contact our KKT chillers service team ( Contact details).
9.2. Condenser
To maintain high performance capability the microchannel heat exchanger must be cleaned if
visibly dirty, however, at least once a year. To do this, safely disconnect the unit from the power
supply and remove the service panels and the condenser safety grille (panel 3 and 5, see
Chapter
1.2 Elements ). Use a standard vacuum cleaner to remove coarse dirt particles from the outside
first. Then carefully flush the inside of the microchannel heat exchanger in the opposite direction
to the air flow with hot tap water. Then clean with a wet vacuum cleaner until the surface is once
again dry. For versions with a water-cooled condenser refer to the complete cooling of the cold
water circuit.
9.3. Water filter
To ensure the required water quality and the necessary circulating water quantity the optionally
available water filter (
Chapter 3.27 Liquid circuit filter assembly ) must be checked for dirt at least
once a month. The suitable filter unit can be ordered as an original spare part at any time – please
contact our KKT chillers service team (
Contact details) .
9.4. Complete cleaning of the cold water circuit
Due to the complexity and diversity of the possible external materials we recommend complete
cleaning of the cold water circuit is carried out by qualified personnel only – to this end, please
contact our KKT chillers service team (
