ROTATION DIRECTION

The machines must be used respecting the rotation direction indicated by the
arrow on the electric motor fan cover.

To check the rotation direction, switch the motor on briefly and observe the
fan.

To change the rotation direction, invert the power cable connections,
leaving the earth connection unchanged.

refer to the connection diagram located inside the terminal box and in this
section
ATTENTION!
The position of the motor does not always allow the rotation direction to be checked, therefore it is advisable to do this check before
installation in the system.

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 the "SPECIFICATIONS";

Respecting the values given in the "SPECIFICATIONS" and the electric motor RATING DATA.

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! (if not foreseen).

Make sure the ambient and conveyed gas suction temperatures come within the values: -15°C (+5 °F)÷ +40°C (+104 °F).

Check the operation of any flow control/limiting devices.

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.

Respect the values given in the "SPECIFICATIONS" and the electric motor RATING DATA.". Pressure losses in the pipes are
often underestimated but are decisive factors for the operating pressure differential.

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.

On shutdown, make sure to operate the unit with open outlet (suction/ delivery) for about 20 minutes. This operation allows the
removal any condensate inside.

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:
