Installation and operating instructions Wilo-CronoLine-IL/CronoBloc-BL (with cartridge mechanical seal)
The glanded pumps of the IL (in-line single pump) and BL (monobloc
pumps) series are meant to be used as circulators in building services.
They may be used for:
• Hot-water heating systems
• Cooling and cold water circulation systems
• Process water systems
• Industrial circulation systems
• Heat carrier circuits
Typical installation locations are technical rooms within the building
with other domestic installations. No provision has been made for
direct installation of the device in rooms used for other purposes (res-
idential and work rooms).
For these series, it is possible to set them up outdoors only in their
corresponding, special version, on request (see chapter 7.3 "Anti-
condensation heater connection" on page 46).
CAUTION! Risk of property damage!
Non-permitted substances in the fluid can destroy the pump.
Abrasive solids (e.g. sand) increase pump wear.
Pumps without an Ex rating are not suitable for use in potentially
explosive areas.
• Intended use includes compliance with this manual.
• Any other use is regarded as non-compliant with the intended use.
