8.1. Periodic checks
The product in normal operation does not require any kind of maintenance. However, it is advisable to periodically check the current
absorption, the manometric head with the mouth closed and the maximum flow rate, which allows you to identify faults or wear in
advance. The mechanical seal does not normally require any control step. You will only have to check that there is no leak of any kind.
If there is a different seal, check the dedicated appendix.
8.2. Emptying the system
If you want to drain the water out of the system, proceed as follows:
1 Disconnect the power supply;
2 Turn on the delivery tap closes to the system so as to remove pressure from the system and empty it as much as possible;
3 If there is a check valve immediately downstream from the system (always recommended), close it so as not to let out the water
that is in the plant between the system and the first turned on tap;
4 Interrupt the suction pipe in the point closest to the system (it is always recommended to have a check valve immediately upstream
from the system) so as not to drain the whole suction system;
5 Remove the drainage cap and let out the water inside;
6 The water that is trapped in the delivery system downstream from the non-return valve integrated in the system can flow out at the
time of disconnecting the system, or on removing the cap of the second delivery (if not used).
Though essentially drained, the system is unable to expel all the water that it contains. During handling of the system after emptying it,
some small amounts of water may probably leak out from the system.
8.3. Modifications and spare parts
Any modification made without prior authorisation relieves the manufacturer of all responsibility.
Only if there is an integrated power cable, in the event of damage to the same, the repair must be carried out by specialized personnel
to prevent any risk.
