Fig. 2 Horizontal installation of MQ
To prevent movement and vibrations, the pump and
base plate can be secured to a solid foundation by
means of the bolt holes in the base plate.
For pipework connection, see section 8.4 Pipework.
The bolt holes are covered by a thin plastic layer that
must be knocked out before use. See fig. 3.

Note
For outdoor installation, the pump
must be fitted with a protective cover
(accessory). See section 8.5 Protective
cover and 14. Accessories.
Caution
Should the unlikely event of an internal
leakage occur, pumped liquid will be
drained out from the base and/or end
cover instead of damaging the pump.
Install the pump in such a way that no
undesirable collateral damage can
arise.
