General Warnings; Maintenance Table - MIL'S ARICA 11 Manual De Utilización

Always ground the pump.
Always install a security system between the pump and the electric power supply ; the circuit‐breaker must be
set according to the amperage shown on the identification plate of the electric motor.
The pump is normally supplied without an electrical cable and switch. For electrical connection, see the diagram
contained within the terminal board or on the motor rating plate.
Check that the direction of rotation is correct before starting the pump for the first time or after
changing the electrical connections.
The correct direction of rotation is indicated by the arrow on the pump. Pump operation with a rotation
direction that is opposite to that indicated can severely damage the pump itself.
3. COMMISSIONING
3.1. Operation
Prior to start up ensure that the pump outlet is not obstructed by fittings.
Warning : risk of burns !
The pump may reach high temperatures when operating. Take steps to prevent people from
accidentally touching the hot parts.
Start‐up
After start‐up, the pump may run slower than the regular rpm if room temperature is lower than allowed as seen
on the technical data table. It may also run lower if the supply voltage is lower than the required voltage as
indicated on the motor rating plate.
If nominal rpm is not reached within a few seconds, the thermal switch fitted to protect the pump must trip
(Installation required in paragraph "Wiring").
It is advisable not to start the pump more than 12 times per hour to avoid excessive energy consumption and
damage to the pump.
Full r.p.m. pump operation must be without vibration or unusual noise. If these are present, stop
the pump immediately, search for the cause and eliminate it.
Stop
The pump must be stopped by cutting off the power supply.
If the pump is to be powered off, let it run with open intake, isolated from the user system, for about 30 minutes
first. This will eliminate any moisture inside the intake chamber and avoid rotor oxidation of the internal parts.

4. MAINTENANCE
4.1. General warnings
For good maintenance:
• Immediately verify the causes of any malfunctions (excessive noise, overheating, etc.);
• Pay particular attention to safety devices;
• Make use of all documentation provided by the manufacturer (instruction manuals, wiring
diagrams, etc.);
• Use only appropriate tools and original spare parts.
Take every possible precaution to protect the environment. In particular, all waste fluids should be
recovered and recycled. Never dispose of these fluids directly into the environment.
It is vital during servicing and maintenance operations to take steps to protect against the risks
associated with moving or live parts.
Before performing any servicing or maintenance operation on the pump:
‐ The pump must be powered off and electrically locked out.
‐ Isolate the pump from the application.
Depending on applications, the pump parts may have been contaminated by the substances
pumped. Apply elementary hygiene rules and use suitable personal protective equipment.
These operations are to be performed by qualified and accredited personnel.
Rubber O ring or rubber flat seals dismantled must be replaced.
4.2. Maintenance table
Operation type
Clean motor fan guard and clean the pump.
Change the intake filter
Change vanes
Radiator, motor fan guard and the pump should be cleaned to remove any dust deposits.
This can be done using compressed air and a dry cloth.
Do not use fluids or substances other than those indicated.
Wear appropriate personal protection equipment to perform said operations.
