MAINTENANCE
UR Fog generators do not require special care, however, it is recommended the support of qualified and authorized
personnel for periodic annual monitoring, taking into account the following:
1) Verify the good working condition of the power supply and battery
2) It is advisable to replace the cylinders after 2 years from the installation
3) Verify the lock of the nozzle ferrule
4) Verify the entirety of the nozzle sphere
5) Check the air tightness of the circuit and the switch functioning
6) Intervention report redaction and release of conformity declaration according to 37/08 order in case of provision
Check the efficiency of the power supply and of the battery
Verify that the tension of the no-load voltage power supply (disconnected battery) is 13,8 V. If tension is different, regulate it
using the trimmer placed on the power supply. Verify the efficiency of the battery (it should not be hot and bloated);
it is suggested to change it every two years due to the heavy and prolonged charge during the shot without mains power.
Entirety of the nozzle sphere
Verificare che il foro sia rimasto cilindrico. La durata media della sfera dell’ugello dipende dal numero e dalla durata
degli spari, indicativamente intorno agli 8 litri di glicole. Sostituire esclusivamente con sfere originali da 7 mm.
Checking of the pneumatic circuit and the pressure control system
THE TEST CAN BE DONE JUST BY QUALIFIED PERSONNEL
he pneumatic seal test must be done within a few seconds when the machine for nozzle tamper control
is turned on, as the nozzle temperature rises rapidly reaching temperatures that may cause serious burns.
The air coming out of the nozzle exceeds 200° C.
Before starting the test of the pressure control it’s necessary:
- to remove the cylinders
- to be sure that the nozzle is cold
- to be sure that the nozzle tamper is activated
