4.1.4 Pump Fixation (Option)
The pumps are provided with casters for easy transportation and foot
adjustments for anchoring and height adjusting, as described in Section 4.1.2.
The pump, however, may unexpectedly move or fall down when an earthquake
occurs. To prevent such events, EV-S dry pumps (CE/SEMI compliant) are
equipped with brackets to secure the pump body to the floor. Fix the pump to
the floor or other firm ground with the brackets at the installation.
For dimensions of the bracket, see the accompanying drawing.
Anchor bolts should be fit for conditions of the floor where the pump is
anchored.
