4 Intended use
This device must not be operated by persons (including children)
with limited physical, sensory or mental abilities or lacking the
necessary experience and/or knowledge.
Children must be supervised to ensure that they do not play with
the device.
These high-efficiency pumps from the UPM series are intended
for the circulation of liquids (no oils, liquids containing oil, no
foodstuff) in:
 Domestic hot water heating systems
 Air conditioning, cooling and cold water circuits
 Heat pumps
 Closed industrial circulating systems.
UPH 80-25P only:
 Primary circuits of brine-to-water heat pumps containing
media with antifreeze (e.g. glycol or ethanol), up to min. -
10 °C
ATTENTION!
Danger of damage to health!

The materials used in the pumps can cause damage to health as they are
not approved for use in domestic water circulating systems. Due not use
pumps in domestic water systems.
