Installation and operating instructions • Wilo-Yonos GIGA2.0-I/-D • Ed.01/2023-03
• Item 6: An unobstructed and free air flow must be ensured around the electric fan. (see
"Installation" [" 128] section).
• Item 7: The protective plate must be dismantled for the leakage check (DN 100, DN 125
only). Observe the safety instructions in "Commissioning" [" 150] section!
Rating plates (Fig. 2)
1 Pump rating plate
• There is a serial number on the pump rating plate. It must be specified e.g. for ordering
spare parts.
• The drive rating plate is located on the side of the electronic module. The electrical con-
nection must be designed according to the specifications on the drive rating plate.

Table 3: Functional assemblies
The motor drives the hydraulic unit. The electronic module takes over the control of the mo-
tor.
The hydraulic unit is not a ready-to-install assembly due to the continuous motor shaft. It is
disassembled for most maintenance and repair work. For information on maintenance and
repair work, see "Maintenance" [" 205] section.
Motor impeller unit
The impeller and lantern together with the motor form the motor impeller unit (Fig. 4).
The motor impeller unit can be separated from the pump housing for the following purposes:
• The motor with the electronic module must be turned to a different relative position to
the pump housing.
• Access to the impeller and mechanical seal is required.
• The motor and hydraulic unit must be separated.
The pump housing can remain in the pipe.
Observe "Permitted installation positions and change of the arrangement of components be-
fore installation" [" 130] section and the "Maintenance" [" 205] section.
