Installation and operating instructions Wilo-BAC
The pumps are exclusively intended for installation and operation in
enclosed rooms. 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 (residential and work rooms).
The following is not permitted:
• Outdoor installation and operation outdoors
CAUTION! Risk of property damage!
Unpermitted 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.
Minimum efficiency index MEI:
The benchmark for most efficient water pumps is MEI ≥ 0,70.
NOTE
For detailed information on the MEI values of the pump types, see:
Wilo online catalogue, available at
www.wilo.com
The efficiency of a pump with a trimmed impeller is usually lower than
that of a pump with the full impeller diameter. The trimming of the
impeller will adapt the pump to a fixed duty point, leading to reduced
energy consumption. The minimum efficiency index (MEI) is based on
the full impeller diameter.
The operation of this water pump with variable duty points may be
more efficient and economic when controlled, for example, by the use
of a variable speed drive that matches the pump duty to the system.
