Page 11: Transportation And Storage
To avoid scoring at the bearings and sticking, turn the pump shaft once a week using a socket wrench. If a longer storage time is required, contact Wilo for preservation measures. WARNING Risk of injury due to incorrect transport! If the pump is transported again at a later date, it must be packaged so that it cannot be damaged during transport. -

Page 16: Scope Of Delivery
The installation options depend on the pump size. Suitable Wilo control devices (e.g. Wilo-CC-HVAC system) can control the power of the pumps continuously. This allows optimisation of the pump output for the demands of the installation and economically efficient pump operation. -

The pump must not be allowed to operate dry for more than 1 minute. Dry running causes a build-up of energy in the pump, which can damage the shaft, impeller, and mechanical seal. • Make sure that the volume flow does not fall below the minimum value Q WILO SE 2021-08... -
Page 19: Preparing The Installation
Preparing the installation Check whether the pump complies with the specifications on the delivery note; report any damage or missing parts to Wilo immediately. Check slat crates/boxes/wrappings for spare parts or accessory components which could be included with the pump. - Page 20 NOTICE For monobloc pumps larger than 30 kW, only horizontal installation is permissible. Install monobloc pumps of the Atmos GIGA-B series on adequate foundations or mounting brackets (Fig. 7). The motor must be supported from a motor power of 18.5 kW. See installation ex- amples Atmos GIGA-B.
- Page 21 This prevents the pump from running dry. The minimum inlet pressure must be observed. NOTICE In the case of insulated systems, only the pump housing may be insulated. Never in- sulate the lantern and motor. Installation and operating instructions Wilo-Atmos GIGA-B...

Page 23: Electrical Connection
Use a heat-resistant connection cable if fluid temperatures exceed 90 °C. ƒ The current type and voltage of the mains connection must correspond to the spe- cifications on the rating plate. ƒ Fuse protection on mains side: Dependent on rated motor current.
