The operational safety of the pump or installation supplied can only be
guaranteed if it is used in accordance with paragraph 4 of the operating
instructions. The limits given in the catalogue or data sheet must under no

3 Transport and interim storage
When receiving the material, check that there has been no damage during the
transport. If shipping damage has occurred, take all necessary steps with the
carrier within the allowed time.

4 Intended use (Application)
CAUTION! Possible damage of the pump
This pump is intended for use with water and water/glycol only.
The circulating pumps are used to circulate liquids in
• Warm and hot water heating systems,
• Cooling and cold water circuits,
• Closed circulation systems.
WARNING! Health hazard
The materials are not designed for drinking water supply.
Permissible liquids and requirements:
• Heating water according the requirements of accepted standards of water
quality in heating systems.
• Water and water/glycol mixtures in a maximum ratio up to 1:1. High glycol
concentration and low temperature systems may require a reassessment of the
hydraulic data to compensate for the increased viscosity (please contact your
WILO representatives for more information). Use of additives (corrosion
inhibitors, oxygen scavengers etc.) must be in compliance with the
manufacturer instructions.
• If other fluids or additives are used, please contact WILO for proper
authorization.
