[email protected]om for further information.
1.3 Health and Safety Notes
WARNING!
WARNINGS ARE GIVEN WHERE FAILING TO OBSERVE THE
INSTRUCTIONS COULD RESULT IN INJURY OR FATALITY.
CAUTION!
Cautions are given where failure to observe the instructions could
result in damage to the equipment, associated equipment and
processes.
1.4 Electricity
WARNING!
THIS APPLIANCE MUST BE EARTHED.
It is essential that the electrical supply to the PURELAB 7000 is isolated before any items are changed or
maintenance work performed.
The external isolator providing power to the unit should be positioned so that it is easily accessible.
1.5 Pressure
The water supply should be isolated and residual pressure released prior to removal of any components or
carrying out work on the unit.
1.6 Sanitization Chemicals
During the sanitization cycle EfferSan™Multi-purpose Disinfecting Tablets or Minncare Cold Sterilant is
used and relevant safety guidance is included in this handbook. Please refer to the manufacturer for material
safety data sheets.
EfferSan™ and Minncare Cold Sterilant are EPA registered as a sterilant, high level disinfectant, and
sanitizer.
EfferSan™and Spent Minncare Cold Sterilant are acidic and require normal neutralization as specified by
your local state and local regulations.
1% of Minncare Cold Sterilant has a pH of 3.5.
1.7 Control of Substances Hazardous to Health (COSHH)
Material safety data sheets covering the various replaceable components are available upon request.

4.1 Night service/Operational day (screen 030)
Refer to Section 3.2 - Steps 13 and 14.
Your PURELAB 7000 - US can be programmed to
operate on specific days between selected times.
This is to optimize the efficiency of the unit and to
minimize any rise in water temperature.
During the sleep period the unit will display .
It is possible to override this mode by PRESSING .
4.2 Continuous Recirculation 24/7 (screen 029)
Refer to Section 3.2 - Step 13.
Your PURELAB 7000 - US can be programmed to
operate on specific days between selected times.
This is to optimize the efficiency of the unit and to
