Discharge air pipe line installation
−
When required, it is possible to pipe the pump
discharge air to other rooms, or outside.
−
Use pipes with the same diameter as the tank
discharge port with a maximum length of 15 m.
For longer pipes increase pipe diameter. Pipe
weights must not rest on the pump.
In the final length use flexible pipes or pipe fit-
tings.
WARNING!
This pipe must be descending, to avoid the con-
densate going back to the tank.
CAUTION
Do not connect ball valves to this pipeline.
Electrical connection
WARNING!
The control panel and electrical connections must
be carried out by skilled personnel and conform to
the EN 62204-1 rules or any other local regula-
tions in the country of use.
CAUTION
The electrical equipment must comply with EN
61000-6-4 and 61000-6-2 standards concerning
electromagnetic compatibility, emission standard
and immunity for industrial environments.
Check the main voltage and frequency in use to
correspond to the data stamped on the motor
name plate.
The electrical motor must be protected against
overload. The full amperage on the motor name
plate must be considered when sizing the electri-
cal components and motor protection against over-
loading.
Make sure the grounding is correctly done.
Carry out the electric connection following the dia-
gram shown on the motor terminal box.
Check direction of rotation by starting the pump for
a short time (2 or 3 seconds). The correct direction
is shown by the arrow on the pump (see figure be-
low). In case of wrong rotation, it is necessary to
change the motor rotation by exchanging position
of two of the three connections in the motor termi-
nal box.
WARNING!
The pump is supplied without lubricating oil.
CAUTION
The operation without oil causes big damages to
the pump.
Carry out the first oil filling through the plug (E) up
to the half of the sight glass (F) and close the plug
(E) (see following figure).
Oil change parts identification
Start the pump and let it run at least 2 minutes.
Stop the pump, check again the oil level and add
some additional oil, if necessary, in order to get the
correct oil level.
