Installation and operating instructions Wilo-Yonos GIGA-N
Application/use
Children and persons younger than 16 years or with reduced physical, sensory or mental
capacities or limited experience are prohibited from handling the device! Persons under
the age of 18 must be supervised by a technician.
The glanded pumps in the Wilo-Yonos GIGA-N series are intended for use as circulators
in building services.
The Wilo-Yonos GIGA-N pumps may be used for:
ƒ
Hot-water heating systems
ƒ
Cooling and cold water circulation systems
ƒ
Industrial circulation systems
ƒ
Heat carrier circuits
ƒ
Irrigation
The pumps are only approved for the fluids specified in the "Technical data" section.
Installation within a building
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). The installation location
must be dry, well ventilated and frost-resistant.
Installation outside a building (outdoor installation)
ƒ
Install the pump in a housing as weather protection. Observe ambient temperatures.
Permissible ambient temperature for outdoor installation, see "Technical data" table.
ƒ
Protect the pump against the effects of weather such as direct sunlight, rain and
snow.
ƒ
Take suitable measures to prevent the formation of condensation water
Intended use also includes compliance with this manual. Any other use is regarded as
non-compliant with intended use.
WARNING! Misuse of the pump can lead to dangerous situations and damage.
ƒ
Never use with fluids that have not been approved by the manufacturer.
ƒ
Non-permitted substances in the fluid can destroy the pump. Abrasive solids (e.g.
sand) increase pump wear.
ƒ
Highly flammable materials/fluids should always be kept at a safe distance from the
device.
ƒ
Never allow unauthorised persons to carry out work.
ƒ
Never operate the pump beyond the specified limits of use.
ƒ
Never carry out unauthorised conversions.
ƒ
Use authorised accessories and genuine spare parts only.
The Wilo-Yonos GIGA-N pump is a single-stage back pull-out centrifugal pump with
spiral housing for horizontal installation. Power and dimensions conform to EN 733.
The drive has an integrated electronic speed control. This allows optimisation of the
pump output for the demands of the installation and particularly cost-efficient pump
operation.
The pump consists of a radially divided spiral housing (optionally with replaceable neck
rings) and cast-on pump support feet. The impeller is a closed radial impeller. The pump
shaft is supported by grease-lubricated radial ball bearings.
AC motors with integrated frequency converters are used as drives.
The fluid pump is sealed via a mechanical seal in accordance with EN 12756.
Depending on the differential pressure and the control mode setting, the electronic
module controls the speed of the pump according to a setpoint which can be adjusted
within the permissible control range.
