Arrangements required from Buyer/User
The client is responsible for the following arrangement.
Checking the condition of the pump when it is delivered. Contact LEUCO S.p.A. in case of damage
conditions that do not match the purchase order
The assembler/end user is responsible for choosing the type of motor - pump coupling and for following
the instructions in this document.
The assembler/end user must fit a maximum pressure valve near the pump delivery line outlet.
The assembler/end user must fit a system that guarantees the hydraulic system will stop immediately in
case of a sudden increase in the pump temperature and/or excessive current absorption.
Follow the instructions provided in the Operating and Maintenance Manual for the machine where the pump is
fitted for all connections.
5.2
Preliminary operations before first start-up
A set of checks and inspections have to be made before the pump is started up to prevent errors or accidents during putting into
service.
•
Check that the machine has not been damaged during assembly, installation and transport (stability, correct screw and/or
bolt fixing, correct coupling of mechanical parts and gears).
•
If leaks are identified from the pressurised piping, stop the pump immediately and remove the cause of the leak.
After making the required connections, the fitter shall carry out a test to check correct operation of all the featured devices.
Start the pump up and keep the delivery line (nozzle) open for easier priming. Do not let the pump run in dry condition. This
may cause quick wearing of the seals, thus voiding the warranty.
After use, run the pump with clean water for a few minutes. Do not expose the pump to very low temperatures. Let the
pump run dry for approx. 20 seconds to drain the pipes and thus prevent frosting.
If the equipment does not appear suitable for correct and safe operation, it MUST BE PUT OUT OF SERVICE
until it is repaired or the damaged parts are replaced.
