4 STARTING OPERATIONS
4.1 Priming
Installation below water level
:
Fit one gate valve in the suction pipe and one in the delivery pipe to isolate the pump.
Fill the pump, slowly and completely opening the gate valve in the suction pipe, and keeping the gate valve on delivery
open to let the air out.
Figure 8
Installation above water level:
If there are several suction pipes, arrange the pipes and the manifold below water level and reach the pump with only
one vertical pipe.
To reduce the priming time, it is recommended to install the pump with as short a suction pipe as possible.
Fill the basket of the filter with water up to the level of the suction mouth.
It is strongly recommended to install a check valve on the suction line to facilitate the priming of the pump.
