WARNING After the safety screw has been removed, disassembly of the valves can be facilitated by by tapping with a mallet on the valve
itself to release the coupling, but solely parallel to the delivery port and not hard enough to damage the surfaces. Block the pump by
holding it by the intake support and not by the pipe, then turn the valve hexagon in the CLOCKWISE direction.
BEFORE reassembling the valve, carefully REMOVE the internal BURR from the safety HOLE, REPLACE THE LIPPED SEAL ON THE
PUMP SIDE WITH A NEW ONE and grease the threaded surfaces.
THE GALVANIC PROTECTOR BETWEEN THE PUMP AND MOTOR AND THE ONE ASSEMBLED ON THE DELIVERY (IF
APPLICABLE) MUST BE REPLACED WHENEVER THE PUMP IS REMOVED FROM THE WATER. NEVER REASSEMBLE THE OLD
ONE UNLESS THE OXIDATED RESIDUES HAVE BEEN PREVIOUSLY CLEANED FROM ITS EXTERNAL SURFACE.
Removal.
Always disconnect the machine from the electricity main that powers the system before proceeding with any work on it. If the electric pump must be
disassembled from the system, work through the instructions given in section 5.4 'Wet connections' and 5.5 'Electrical connections and information'
in reverse order, taking care to check:
1) the weight of the unit which, in certain conditions, can be burdened by that of the water it contains;
2) that the various components always remain stable once they are positioned vertically.
Only use genuine Caprari spare parts, otherwise all forms of warranty and the manufacturer's liability will become void.
Provide Caprari S.p.A. or its Authorized Assistance centers with the following information when ordering spare parts: the complete code of the
product; date code and/or serial number and/or job number when applicable; denomination and reference number of the part given in the spare
parts catalogue (available from authorized assistance centers); number of parts required.
7 DISMANTLING AND DISPOSAL:
When the electric pump unit is dismantled, the operator must work through the dismantling and destruction phases in strict compliance with the local
laws and regulations governing disposal.
End-of-life product disposal.
INFORMATION TO USERS pursuant to Article 14 of the DIRECTIVE 2012/19/EU OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 4
July 2012 on waste electrical and electronic equipment (WEEE)
The crossed-out wheeled bin symbol on the electrical and/or electronic equipment (EEE) or on its package indicates that the product
must be collected separately at the end of its service life and not disposed of with other mixed municipal waste.
DOMESTIC EEE
Please contact your municipality, or local authority, for all the information regarding the locally available separate collection systems. The
retailer of the new equipment has the obligation to take back the old one upon the purchase of an equipment of equivalent type, in order to start the
correct recycling/disposal cycle. In Italy, domestic EEE are electric pumps with single-phase motor. This classification must be verified in the other
European nations.
PROFESSIONAL EEE
The separate collection of this equipment after its useful life is organised and managed by the manufacturer. Therefore, any user that may want to
dispose of this equipment can either contact the manufacturer and follow the system implemented to separately collect the equipment at the end
of its useful life, or autonomously select an authorised waste management chain. In any case, the user must respect the take-back conditions laid
down by the Directive 2012/19/EU.
Illegal disposal of the product by the user shall be subject to the application of the sanctions provided for by law.
8 WARRANTY:
