Puranity TU+ VWR
Chapter 2
Access to the power supply cord and plug may never be restricted or obstructed.
Unplug the system from the power outlet for all maintenance work on the system.
An atmospherically vented floor drain with a nominal diameter of at least 63 mm (2.48 inch)
(DN50 tube) must be present at the installation location. If no drain is provided it is
recommended that a water detector be installed for safety reasons (for European
specifications only). Failure to provide this will release the manufacturer from liability for any
water-induced damage that may result.
Proceed as follows if the system is not to be operated for an extended period, e.g., over
extended weekend, or during a vacation period:
Switch the system off (unplug the mains plug).
Close the feedwater inlet (close the feedwater tap).
The pump would be damaged if the system were to run without any supply of feedwater. The
manufacturer will not accept any liability should this occur.
The system must be disinfected or rinsed after an extended down time. The cleaning
procedure is described under “Cleaning” on page 53.
The surface or wall on which the system is to be installed or mounted must have an adequate
load-carrying capacity (check the capacity and stability of the wall). The dry weight of the
system is given under “Dimensions and weight Puranity TU 3 +/6+” on page 14 and
“Dimensions and weight of Puranity TU 12+” on page 15.
The surface on which the system is installed must be level and stable not to exceed a
maximum of 2% deviation from evenness is recommended.
When installing the water purification system, always ensure that there is adequate space all
around the system (see “Accessibility to Puranity TU+ systems and pure water tank” on
page 17.) to ensure that ease of use or easy replacement of materials (e.g., filter change,
connection) is possible at all times.
Visually inspect the system at regular intervals. Clean up any water or spills found around the
system immediately.
