4.4 Install the system
Requirements to secure the system in place to prevent unwanted movement (for
example, during an earthquake):
▪ A minimum of 2 seismic brackets are necessary to secure the pump.
▪ The seismic brackets ( Figure: Front view of the system ) are designed to withstand a
level 4 earthquake in a ground floor installation (available as an accessory). Refer
to Accessories on page 93.
▪ There are seismic mounting points along the sides of the pump. If you have to
consider space constraints, there are alternative seismic mounting points on the
front and rear bulkhead.
▪ The system can be attached to the floor with applicable bolts or studs (not
supplied) through the 17.5 mm diameter hole in the seismic brackets.
▪ If vibration transmission to the floor is a possible problem, attach vibration
isolators (not supplied) between the seismic brackets and the bolt or stud.
▪ Make sure that the bolt spacing is sufficient for the floor strength and expected
loads.
▪ The system has mounting points to attach four seismic brackets as shown in view A
of Figure: Reduce the effective system footprint . On smaller systems, two brackets
can hold the system during an earthquake. The smaller systems can be attached as
shown in view B of Figure: Reduce the effective system footprint , to decrease the
effective system footprint. if necessary, view C of Figure: Reduce the effective
system footprint and Figure: Reduce the effective system footprint iXM3000 also
shows an alternative way of reducing the system’s footprint, where the seismic
brackets are securing the system from the front and back. Refer to Accessories on
page 93 to select the correct seismic bracket kit for the system and for information
about the systems which can be held with only two brackets.
