Installation and operating instructions Wilo-Atmos GIGA-N
Product description
Intended use also includes compliance with this manual. Any other use is regarded as
non-compliant with the intended use.
The Wilo-Atmos GIGA-N pump is a single-stage back pull-out-centrifugal pump with
spiral housing for horizontal installation. Power and dimensions in accordance with
EN 733.
Suitable Wilo control devices (e.g. Comfort control system, CC-HVAC) can control the
power of the pumps continuously. This allows optimisation of the pump output for the
demands of the installation and particularly economically 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.
The system is driven by IEC standard motors in a three-phase current version.
NOTICE
Use a heat-resistant mains connecting cable in systems where fluid temperatures
exceed 90 °C!
The fluid pump is sealed via a mechanical seal in accordance with EN 12756.
Operation on the frequency converter is permitted. Refer to the documentation from
the motor manufacturer for the relevant requirements and observe its contents.
