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)
The high-efficiency pumps of the Wilo-Stratos/-D/-Z series are used to
circulate fluids (no oil or oleiferous fluids, no foodstuffs) in
• Hot water heating systems,
• Cooling and cold water circuits,
• Closed circulation systems.
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.
CAUTION! Risk of injuries to personnel and damage to property!
Incorrect transport and interim storage can cause damage to the product
and injury to personnel.
• The pump and its packaging must be protected against moisture, frost and
mechanical damage during transport and interim storage.
• Packaging that has become weakened due to moisture may allow the pro-
duct to fall out, causing injury to personnel.
• When the pump needs to be transported, it may be carried only by the
motor/pump housing. Never carry it by the module/terminal box, cable or
external capacitor.
CAUTION! Possible damage of the pump!
This pump is intended for use with water and water/glycol only .
WARNING! Health hazard!
The materials of the Wilo-Stratos/-D can cause damage to one's health,
since they are not approved for use in secondary hot water circulation
systems.
Do not use Wilo-Stratos/-D pumps in secondary hot water systems.
