3 Application/use
3.1 Intended use
The glanded pumps in the Wilo-Atmos GIGA-N series are intended for use as circulators
in building services.
The Wilo-Atmos GIGA-N pumps may only be used for:
▪ Hot-water heating systems
▪ Cooling and cold water circulation systems
▪ Drinking water systems (special version)
▪ Industrial circulation systems
▪ Heat carrier circuits
▪ Irrigation
The pumps are only approved for the fluids specified in the “Technical data” section.
3.2 Improper use
WARNING! Misuse of the pump can lead to dangerous situations and damage.
▪ Never use with fluids that have not been approved by the manufacturer.
▪ Non-permitted substances in the fluid can destroy the pump. Abrasive solids (e.g. sand)
increase pump wear.
▪ Highly flammable materials/fluids should always be kept at a safe distance from the
device.
▪ Never allow unauthorised persons to carry out work.
▪ Never operate the pump beyond the specified limits of use.
▪ Never carry out unauthorised conversions.
▪ Use authorised accessories and genuine spare parts only.
Typical installation locations are technical rooms within the building with other do-
mestic installations. No provision has been made for direct installation of the pump in
rooms used for other purposes (residential and work rooms).
Outdoor installation requires a corresponding, special version (motor with anti-con-
densation heater).
