1. Process water inlet a Process water outlet When filling the circuit with liquid check to ensure the absence of air bubbles and l PLUG contaminants If the pump runs noisily or emits anomalous noise it may be necessary to a bleed the liquid circuit in order to prime the pump The procedure is as follows unscrew the filler breather plug at the top of the pump e fill the hydraulic circuit until water starts to overflow from the filled hole e refit the plug and tighten it Repeat the operation if the pump continues to run noisily in such a way as to eliminate any air that had previously remained trapped in the impeller vanes In the event of double pump keep particular attention during priming the pump It is necessary to verify first the pump positioned on the top 5 5 Expansion tank If the hydraulic circuit is of closed type it is necessary to install an expansion tank The expansion tank must always be connected at pump inlet To calculate the minimum volume of the expansion tank required for a given installation the formula below cab be used and is valid if the pressure is less than or equal to 0 5 bar when the pump is stopped and the maximum working pressure of the expansion tank is greater than or equal to 4 bar The volume of the expansion tank V in litres is given by the formula V 2 Vt Ptmin
