Lighting
All areas must be illuminated evenly and sufficiently to ensure all operations included in this manual and must be
without shadows, reflections, glare or eyestrain.
4.6
PUMP INSTALLATION
To ensure perfect pump operation, house and place it according to the following conditions:
•
Allow sufficient space on the perimeter sides of the pump and make sure to keep the motor ventilation side free.
•
Make sure the free space adjacent to the pump allows easy access to components for inspection or
maintenance and also allows access for suitable lifting equipment.
•
The pump is equipped with mounting points. It is necessary to ensure it locks onto a perfectly horizontal plane in
order to avoid tilting in case of transportation by the system user.
•
Some models are already equipped with rubber vibration dampers installed at pump attachment points. Whenever the
model has not been equipped, ensure installation of such equipment so as not to transmit vibration to the pump.
•
Ensure there is ventilation in the room, or inside the machine housing the pump and prevent air coming in from
the outlet or cooling fans, which could cause discomfort to personnel.
WARNING
Do not install the pump in any area with dust or other materials that could clog or rapidly cover
cooling surfaces of the heat exchanger (where installed).
4.7
MOTOR INSTALLATION (ONLY LC.105WR)
It is possible to install any type of electric or hydraulic motor that has the
features described in the table of technical data, with flange and shaft
corresponding to M100/4 - B5 size as per standard IEC-72.
WARNING
Install fan/coupling assembly on the motor following these
instructions:
•
Fit the assembly on the motor shaft up to reaching the stated measure,
•
Tighten screw “A” to firmly fix the assembly to the shaft.
4.8
USER SYSTEM
Make sure that no harmful substances contaminate the user system during installation.
If you wish the system to maintain vacuum even when pump is stopped, install a cutoff valve between
pump and system.
Make sure that no vibrations or stresses are transmitted to the pump connection.
4.9
CONNECTION
HAZARD
Pump connections should be performed by skilled and trained personnel only.
4.9.1
ASSEMBLING THE INTAKE FILTER (ONLY LB.5WR)
For packaging and shipping purposes, the filter is supplied disassembled. For connection to the pump a special ring
nut connector with O-ring seal has been provided, which guarantees a perfectly tight coupling. For assembly, just
move the filter towards the intake and screw the ring nut onto the connector.
4.9.2
INTAKE AND OUTLET CONNECTIONS
User system connections (both intake and outlet) must be performed with pipes with a diameter equal to or greater
than the pump suction inlet. The weight of pipes or any expansions must not burden the pump.
It is advisable to make the final connection to the pump using flexible pipe or fittings. It is important to tighten all
pipes and couplings. Very long pipes or pipes with a diameter that is too small diminish pump performance.
HAZARD
Make sure that discharged gases are let out of the workplace.
