The SI1800 or Si-82 centrifugal monobloc pumps are designed for use with all kinds of Air conditioning
units, refrigeration display cabinets, fan coil units and condensing boilers. They can also be used with gas
red furnaces. The pump can be used to remove acid condensates (pH > 2.5) and condensates with a
temperature of up to 65°C.

WARNING
- This pump has been designed for use with water only.
- This pump has been designed for indoor use only. It must not be immersed and/or placed in areas of high
humidity or where the ambient temperature conditions are below freezing.
- The appliance is not to be used by children or persons with reduced physical, sensory or mental capabili-
ties, or lack of experience and knowledge, unless they have been given supervision or instruction.
- Children should be properly supervised to ensure they do not play with the appliance.
- In case of breakdown, in particular if the supply cord is damaged, it must be replaced by a Sauermann
service agent or a similarly qualied person in order to avoid any hazard.
- For models tted with a supply cord without a plug, a means for disconnection must be incorporated to the
xed wiring in accordance with local wiring rules.
WARNING: Risk of electric shock. This pump is supplied with a grounding cable and a grounding
attachment plug. To reduce the risk of electric shock, ensure that the pump is connected only to a suitable
grounding device.
