• Th s t must b fitt d in a w ll v ntilat d plac , prot ct d from unfavourabl w ath r conditions.
• Wh n handling th s t, lift it by th bas .
• Do not lift th s t by th d liv ry manifold: risk of damag .
• Position th s t in such a way that any maint nanc jobs can b carri d out without difficulty.
• Ensur that th syst m pip s ar ind p nd ntly support d and do not w igh down on th s t manifolds
so as to avoid d formation or br aking of any of its compon nts.
It is also advisabl to ins rt vibration-damping couplings on th syst m manifolds.
Mak th intak s ction following all th pr cautions n c ssary to k p load loss s to a minimum and to avoid
th formation of air pock ts, for xampl :
• Position th s t as clos as possibl to th pow r supply sourc .
• Consid r a suction pip diam t r n v r small r than that of th manifold.
• Lay th suction pip horizontally or sloping slightly upwards towards th s t.
• Avoid using lbows or couplings that caus sudd n chang s in dir ction. If n c ssary, us b nds with a
wid radius.
Installation must b p rform d by skill d and authoris d install rs. During installation, apply all
saf ty b haviours issu d by th comp t nt bodi s and sugg st d by common s ns . Install th unit in a dry
w ll-v ntilat d plac . R st th unit on a flat, r gular and solid surfac (rubb r f t) or disass mbl th rubb r
f t and fix th unit to th bas using th r l vant scr ws. Vibrations must not occur during functioning. Th
unit can only b install d in th horizontal position. In th applications with positiv suction h ad, th suction
pip must not b small r than that of th intak manifold. In th applications with n gativ suction h ad, in
particular cas s th r may b th n c ssity to r plac th intak manifold with an individual supply for ach
pump, in ord r to pr v nt pr f r ntial flows to on or s v ral pumps. G n rally, in n gativ suction h ad
applications, th intak pip s must b as short and straight as possibl , th y must hav a diam t r gr at r
than or qual to th diam t r of th pump intak (or th manifold if pr s nt). Th y must also b suppli d
with foot-valv and hav a slight slop to th pumps, to pr v nt th formation of air pock ts. Functioning with
l aks in intak can damag th unit pumps. Fix car fully th piping in ord r not to transmit str ss of any typ
to th pump. Fast n th piping to th r sp ctiv manifolds, without xc ssiv forc so as not to caus damag .
Boost r s ts can b shift d in diff r nt ways d p nding on th configuration of th machin and quipm nt
availabl to th install r.
Wh n making th li
