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
Material safety data sheets covering the various replaceable cartridges are
available upon request. Contact your local supplier or distributor.

DESCRIPTION
3.1 Product Description
The MEDICA water purification system has been specifically designed
to provide a supply of purified water to clinical analyzers requiring a
pressurized feed.
The MEDICA can be bench or wall mounted with an optional wall
mounting kit. A range of accessories are available to complement the
unit. (See Section 11.1 –Consumables and Accessories, for detail).

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.
