Installation - Wilo -CronoLine IL 250 series Einbau- Und Betriebsanleitung

5.2 Installation

Installation only after all welding/soldering on the pipework is completed and the pipe
system has been flushed out. Foreign matter and impurities may cause damage to
the pump.
The pump must be carefully handled by means of authorized lifting gear (see chap. 3).
Isolating valves must be provided and installed on suction and discharge ports in
order to avoid draining the whole pipe system when servicing or exchanging the
pump.
Pump must be mounted free of stress from the pipework. The pipes must be
attached in such way that the pump does not bear the weight of the pipes.
Mounting position: Only vertical installation is allowed!
Sample for foundation:
When installed, the complete set is to be aligned on the foundation using a spirit
level (with shaft/pressure pipe joint). The distance between the coupling halves in
accordance with the installation plan is to be observed. Always fit dummy sheets
(B) on left and right in the immediate vicinity of the fixing material (e.g. stone bolts
(A)) between base (E) and foundation (D). If the fixing holes are longer than
mm additional dummy sheets are to be provided. All dummy sheets must fit
snugly.
