4 WATER CONNECTIONS
Flow Switch
The flow switch must be present to ensure shutdown of the unit if
water is not circulating.
It has to be installed in a duct rectilinear part, not in proximity of
curves that cause turbulences.
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

 Pumps


storage tanks

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.
Admissible water flow-rate
Minimum (Qmin) and maximum (Qmax) admissible water flow for
the unit to operate correctly.
