Operations sequence
Before starting the unit pump :
1 close all vents in the high points of the unit’s water circuit.
2 close all drain shut-off valves in the low points of the unit’s
water circuit:
Heat exchangers
Pumps
collectors
storage tank
3 Wash the system thoroughly with clean water:
use the bypass to exclude the exchanger from the flow
(diagram on the previous page)
fill and empty the system multiple times.
4 Apply additives to prevent corrosion, fouling, formation of mud
and algae.
5 Fill the system
Do not use the unti pump.
6 Conduct a leak test.
7 Isolate the pipes to avoid heat dispersions and formation of
condensate.
8 Leave various service points free (wells, vents, etc).
Note
Neglecting to wash will lead to the filter having to be cleaned
many times and at worst may damage the exchangers and
other parts
