Axial-flow hollow cone nozzles
A person (or persons) in charge appointed by the user must familiarize with user's installation and the operating personnel
with the way in which the nozzle in question functions and should be handled.
The following must be carried out every time before a nozzle is used:
Check that the connections are secure and not leaking.
§ §
Function test (according to common possible problems)
§ §
Check the effectiveness of general occupational safety measures, bearing in mind the applicable regulations, particularly
§ §
in the case of applications that create a potentially hazardous or explosive atmosphere.
TC 10.2 PIPE MAINTENANCE
Verify that the spray's pipes are not occluded, it can happen if the quality of water is not as requested before (suggested
10 hours after the first use and then every 200 hours)
During the peaks of air temperatures or when it is necessary, spray nozzles are working when MV4 is opened, MV5 is
§ §
closed and manual valve is closed (optionally pump active).
Every time the Adiabatic system is switched off (MV4 closed // MV5 opened) thanks to the automatic opening of the
§ §
optional NA valves.
During the autumn and/or winter period when the equipment is not operating, in order to avoid the formation of ice,
§ §
the connection from the water system to the pump (or plant inlet) must be emptied and the power supply panel must be
deactivated. For this period only, we advise you to also keep the manual drain valve open.
When Adiabatic function is restored, it is important to check the water supply of the pump, the water pressure (>2 bar),
§ §
the activation of the power supply panel and the switching of the solenoids. It is advisable to have a flow switch installed
on the water supply pipe, which will be at the user's expense.
To avoid the risk of ice formation during periods when the ambient temperature is <5 °C, the racks must be emptied.

TC 10.3 CLEANLINESS OF COIL
Periodically, the batteries must be inspected and cleaned to avoid fouling with scale. According to the water specifications
there must not be any deposits of salts or limescale on the coil surface; in the case that they are present, it is necessary to
check the water treatment system, which is probably not operating correctly. In any case we recommend an inspection of
the coils at least twice during each season of water spray operating.
Please examine the instruction manual of unit in order to follow the correct procedure to clean the coil.
