Before starting, the pump must be primed. For installation with no inlet pressure, please follow the procedure
as shown in Fig. 8.
1. For installation with inlet pressure, remove the priming plug and allow the water to ow into the priming
chamber until all air is expelled.
2. The priming procedure should be repeated until all air is expelled and the pump delivers a full stream of
water without bubbles.
3. The pump must always be checked for prime if not used for a prolonged period. It is imperative to ll the
pump with liquid before operation as dry running causes irreparable damage to the mechanical seal.
