1. INTRODUCTION
1.1 Use of this Manual
ELGA LabWater strives to produce manuals that are as simple and accurate
as possible. However, should you feel they can be improved in any way
please email us at [email protected]
This manual guides you through the installation, commissioning and basic
operation of the MEDICA EDI - US allowing you to obtain a guaranteed
supply of purified water to meet your requirements. For more detailed
information refer to the Operator Manual supplied on CD.
1.2 Customer Support
Service support and consumable items are available from your local supplier
or distributor. Please contact [email protected] 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
It is essential that the electrical supply to the MEDICA EDI - US is isolated
before any items are changed or maintenance work performed.
The appliance coupler (mains lead) connected to the rear of the unit can be
removed to isolate the power supply. If access to this is restricted then it is
recommended that access to the supply socket is easily available to
disconnect the electrical supply.
The unit must be earthed. Use of the recommended appliance coupler will
ensure adequate earth protection.
WARNING! IF THE EQUIPMENT IS USED IN A
MANNER NOT SPECIFIED BY ELGA,
THE PROTECTION PROVIDED BY
THE EQUIPMENT MAY BE IMPAIRED.
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.
Switch off the process and relieve pressure in the distribution loop by
opening a point of use or dispense tap.

1.6 Hydrogen
Small quantities of Hydrogen gas are present in the drain line. Drain
must be in a ventilated area.
1.7 Sanitization Chemicals
During the automatic sanitization cycles, EfferSan™multi-purpose
disinfecting tablets and Minncare cold sterilant are used and relevant
safety guidance is included in this Manual. 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 acidic and requires
normal neutralization as specified by your local state and local
regulations.
1% of Minncare cold sterilant has a pH of 3.5.

4. OPERATION
4.1 Night service/Operational day (screen 030)
Refer to Section 3.2 - Step 14 and 15.
Your MEDICA EDI - US can be programmed to operate on specific
days between selected times. This is to optimize the efficiency of the
unit and to minimize rises in water temperature.
During the ‘sleep’ period the unit will display .
It is possible to override this mode by PRESSING .
During the ‘sleep’ period the unit will run in intermittent recirculation
(10 minutes every two hours) to maintain water purity around the
distribution loop.
4.2 Continuous Recirculation (24/7) (screen 029)
Refer to Section 3.2 - Step 13.
If the unit is set to continuous recirculation, it will constantly re-
circulate the water and fill the reservoir as required.
It is recommended that the system only runs in continuous mode
when the demand for water is high (greater than 50% of the make up
flow)
During recirculation the water temperature will tend to increase
slowly.
