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
Exchangers
Pumps
collectors
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.
