2. HEALTH AND SAFETY NOTES
MEDICA products have been designed to be safe, however, it is important
that personnel working on these units understand any potential dangers. All
safety information detailed in this handbook is highlighted as WARNING and
CAUTION instructions. These are used as follows:
WARNING! WARNINGS ARE GIVEN WHERE FAILING
TO OBSERVE THE INSTRUCTION COULD
RESULT IN INJURY OR DEATH TO
PERSONS.
CAUTION! Cautions are given where failure to
observe the instruction could result in
damage to the equipment, associated
equipment and processes.
2.1 Electricity
It is essential that the electrical supply to the MEDICA is isolated before any
items are changed or maintenance work performed.
The ON/OFF switch is located at the left-hand side of the unit. The mains
power lead is located just behind the ON /OFF switch.
WARNING! THIS APPLIANCE MUST BE EARTHED.
2.2 Pressure
The main water supply pressure should be isolated and residual pressure
released prior to removal of any cartridges or carrying out work on the unit.
2.3 Ultra-violet Light
The MEDICA unit is fitted with an ultra-violet (UV) lamp. The UV lamp is
enclosed in a stainless steel chamber ensuring the operator will not be
exposed to UV light.
2.4 Sanitization Chemicals
2.4.1 Liquid sanitization
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.
2.4.2 Tablet sanitization
During the sanitization cycle ONE of EfferSan™multi-purpose disinfecting
tablet is used and relevant safety information is included in this handbook.
Please refer to the manufacturer for material safety data sheets.
EfferSan™is EPA registered as Multi-purpose disinfecting tablets.
2.5 Material Safety Data Sheets

3.2 Process Description
The MEDICA process links four purification technologies, reverse
osmosis, adsorption, ion-exchange and photo oxidation and also
incorporates a delivery pump and an optional RO feed water boost
pump.
The unit is designed to operate from a good quality potable water
supply, and produces either 7 or 15 liters per hour of purified reverse
osmosis grade water which is delivered to a treated water reservoir.
This water is then further purified when demanded by the analyzer.
A graphics screen displays the system status and provides control by
means of three function buttons.
The water is processed and treated by the MEDICA unit as follows:
Potable water enters through a strainer and inlet solenoid
valve at either regulated mains water pressure, or is pumped
by means of a feed water pump (optional), and passes
through the pre-treatment cartridge. The pre-treatment
cartridge has been designed to protect the reverse osmosis
cartridges from particulate/colloidal matter and excessive
free chlorine, which may be present in the incoming feed
water.
The water then passes through one or two reverse osmosis
cartridges, set up in series, which split the flow into permeate
and concentrate streams. The permeate water is further
purified whilst the waste concentrate stream is passed to
drain.
The permeate water passes through a water quality sensor
which measures the conductivity of the water and is
delivered to the treated water reservoir.
The MEDICA is designed to operate with a treated water
reservoir, and to ensure the quality of the water is at its
highest level, the water from the tank is drawn back into the
unit by an in-built delivery pump.
The delivery pump is controlled by means of a pressure
switch which senses when the analyzer demands water.
Permeate water is pumped through the UV chamber where it
is exposed to intense UV radiation.
The partially purified water then passes through the ion-
exchange cartridge which removes dissolved ionic impurities
from the permeate water.
The water is passed through a:
Water quality sensor, which measures the resistivity of
the water.
Temperature sensor which provides accurate
temperature measurement.
The purified water then passes through a 0.2µm filter which
provides the final filtration.

5. INSTALLATION INSTRUCTIONS
5.1 Unpacking the MEDICA
The following items should be supplied with your MEDICA:
1. MEDICA unit
2. Cartridge pack LC141
3. By-pass block fitted in the unit
4. Installation kit (LA637-US)
5. Operator manual
6. Mains lead
7. Black 'clip on' bend former x 4
5.2 Positioning the MEDICA
Before commencing with installation and operation of the MEDICA
unit, please read and observe the following points.
Environment
The unit should be installed on a flat, level surface, in a clean,
dry environment. The unit can also be wall mounted against a
vertical wall capable of supporting the weight (for this we
recommend the use of the wall mounting kit Part No LA610).
CAUTION!If unit is to be wall mounted, ensure it is
mounted on a substantial brick or concrete
solid wall capable of supporting the
operating weight of the system. If
mounting the unit on the wall, use the wall
mounting kit and follow the instructions
included in the kit.
Note: Refer to specifications for unit weights.
The unit is designed to operate safely under the following
conditions:
Indoor Use
Altitude up to 2000m
Temperature range 5 - 40°C
Maximum relative humidity 80% @ 31°C decreasing linearly
to 50% @ 40°C, non-condensating
The unit is in Installation Category II, Pollution Degree 2, as per
IEC1010-1.

MEDICA 7/15 Operator Manual ELGA
Page 12 MEDICA 7/15 US Version 2–10/15
Electrical
The units can be connected universally to any electrical supply
in the range of 100 - 240V and 50 - 60Hz. The mains lead is
supplied with a molded plug on one end and a molded
connector to the unit on the other. The unit should be connected
to an earth.
Drain
A semi rigid flexible connection to a sink or suitable drain
capable of handling at least 1.5 l/min is required. The drain point
should have a gravity fall below the level of the unit and any
connections direct to drain should have an air-break device
fitted.
Feed Water
The feed water should be of good quality and comply with
specifications provided. This should enter the unit via an 8mm
(5/16") O/D semi rigid tube, and should be in the temperature
range 1 to 35°C.
CAUTION! Operating temperatures outside the range
1 to 35°C will cause damage to the MEDICA
unit.
For pressurized feeds, the minimum direct inlet pressure is
4.0 bar (60 psi) and maximum inlet pressure is 6 bar (90 psi).
Higher feed water pressures must be reduced using a pressure
regulator valve (Part No LA512).
Reservoir feeds to the MEDICA unit should be positioned at the
same height, or above the unit, to provide a positive flooded
inlet pressure.
