Sign off on the machine inspection

This procedure is for cleaning water rinse condenser coils / hydronic freecooling coils.

In environments with a high concentration of air-borne particles, it might be necessary to clean the condenser coils more often.

Clean condenser banks with clean water

Clean water heat exchangers with appropriate chemicals

Particles and fibers could clog up the exchangers, especially for water exchangers pay attention if water rich in calcium carbonate is used.

Check for increase in pressure drops

Check for decrease in thermal efficiency

An increase in pressure drops or a decrease in thermal efficiency means that the heat exchangers are clogged.

In environments with a high concentration of air-borne particles, it might be necessary to clean the condenser bank more often.
