Glanded pumps in the LRE series (in-line single) and JRE series (in-line
double) are intended for use as circulation pumps in building services.
They may be used for:
• Hot water heating systems
• Cooling and cold water circulation systems
• Industrial circulation systems
• Heat carrier circuits
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!
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.
• The intended use includes complying with these instructions.
• Any other use is considered to be outside the intended use.
