Installation and operating instructions Wilo-IL/-DL/-BL
The glanded pumps of the IL (Inline), DL (Double) and BL (Monobloc)
series are meant to be used as circulation pumps 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. Installing the device directly in
other used rooms (residential and work rooms) is not intended.
For these series outdoor installation is only possible with the corre-
sponding special versions (motor with standby heating and fan cover
protective roof, see section 7.3 on page 32).
CAUTION! Risk of damage!
Impermissible substances in the fluid can destroy the pump. Abra-
sive solids (e.g. sand) increase pump wear.
Pumps without an Ex certificate are not suitable for use in poten-
tially explosive areas.
• The correct use of the pump/installation also includes following
these instructions.
• Any other use is considered to be incorrect use.
