13 STARTUP
Non-compliance with the unit's intended use can cause serious accidents.
The unit must only be started:
• after carefully reading, understanding and complying with this user manual ("SAFETY RULES" and "INSTALLATION");
•
in conformity with its intended use as prescribed in "FORESEEN USE";
• respecting the values given in the "SPECIFICATIONS".
13.1 PRELIMINARY CHECKS
Before starting the machine for use, carry out the following preliminary checks:
•
If the unit has not been started up for some time, check its condition and, if necessary, remove any dust from the external surfaces;
•
Deactivate/open any pipe closing devices (shut-off valves, solenoid valves, etc.) before starting the unit.
•
Never start and operate the unit with the inlet and/or outlet port closed!
•
Make sure the ambient and conveyed gas suction temperatures come within the values: -15°C (+5°F)÷ +40°C (+104°F);
•
Check correct operation of the pressure-relief valve (not supplied).
13.2 OPERATION
The unit can be started for use after carrying out the preliminary checks.
•
Start the unit by switching on the power to the electric motor.
• Check the operating pressure or vacuum and also compliance with the values given in the "SPECIFICATIONS". Pressure losses in
the pipes are often underestimated but are decisive factors for the operating differential pressure.
• Measure the motor absorption and check compliance with the rated value.
13.3 STOPPING
•
The unit must be stopped by switching off the power supply to the motor.
•
In case of shutdown, make sure to operate the unit with the inlet open for about 20 minutes.
This operation allows the removal any condensate in the suction chamber.
14 MAINTENANCE
In order to prevent faults and damage it is important to periodically check the units in operation, therefore it is advisable to adopt a
maintenance plan in line with this Manual, providing for:
•
Periodical checks
•
Periodical maintenance and troubleshooting
14.1 PERIODICAL CHECKS
The units in operation should undergo periodical inspections by qualified personnel, in order to prevent failures that can directly or
indirectly cause damage.
A) With the unit in operation periodically check the following parameters:
•
Delivery temperature
•
Operating pressure and/or vacuum
•
Electric motor current absorption
•
Vibration
•
State of the filter and corresponding pressure loss
Danger of burns caused by contact with hot surfaces of the unit!!
When in operation the blowers / exhausters can reach high surface temperatures.
Before carrying out any operation after shutdown wait at least 20 minutes for the unit to cool.
