INTRODUCTION
1.1 Use of this Manual
ELGA LabWater strive 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 30/60/120 allowing you to obtain a
guaranteed supply of purified water to meet your requirements.
1.2 Customer Support
Service support and consumable items are available from your local
supplier or distributor. Please contact inf[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 30/60/120 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.
WARNING! THIS APPLIANCE MUST BE
EARTHED.
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 Sanitization Chemicals
During the sanitization cycle Minncare Cold Sterilant is used and
relevant safety guidance is included in this handbook. Please refer to
the manufacturer for material safety data sheets.
Minncare Cold Sterilant is EPA registered as a sterilant, high level
disinfectant, and sanitizer.
Spent Minncare Cold Sterilant is 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.

The Master Key should be stored in a safe place. The Master Key
controls the access level of the other User Keys.
User Keys only have access to customer preference screens.
Sanitization Keys start the sanitization process and stop the general
user from accidentally starting sanitization.
CAUTION! If the Master Key is lost a new Key can only
be programmed by ELGA Service
Engineers.
3.2 System Preferences
When the MEDICA unit is started for the first time after completing

4. OPERATION
4.1 Night service/Operational day (screen 030)
Refer to Section 3.2 - Step 14 and 15.
Your MEDICA 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.
