
Thoroughly wash the system with clean water:
use the bypass to exclude the exchanger from the flow
(diagram on previous page) fill and drain the system several
times.

Apply additives to prevent corrosion, fouling, formation of mud
and algae.
 Fill the system
do not use the unit pump

Conduct a leak test.

Isolate the pipes to avoid heat dispersions and formation of
condensate.
 Leave various service points free (wells, vents, etc).
 Neglecting to wash will lead to the filter having to be cleaned
many times and at worst may damage the exchangers and
compressors.
