2. HEALTH AND SAFETY NOTES
MEDICA-R 7/15 US 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-R 7/15 US 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-R 7/15 US unit is fitted with an ultra-violet 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 sainitization
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.

3.2 Process Description
The MEDICA-R 7/15 US process links five purification technologies,
reverse osmosis, adsorption, ion-exchange, photo-oxidation and sub-
micron filtration. It also incorporates a recirculation/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 further purified and circulated through a
treated water reservoir. This water is available on demand by the
analyzer at up to 1.8 l/min.
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-R 7/15 US 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 feedwater.
The water then passes the sanitization port and 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.
The permeate water is drawn into the main recirculation stream by
the recirculation pump together with water from the reservoir and
passes through the recirculation purification loop.
This water is pumped directly through the UV chamber where it is
exposed to intense UV radiation to provide continuous bacterial
control by photo-oxidation and to promote the cleavage of organic
molecules.
The partially purified water then passes through the ion-exchange
cartridge which removes dissolved ionic impurities from the 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 passes through a 0.2 µm filter to remove any
remaining bacteria.
The purified water is either delivered to the analyzer or returns to
the reservoir. The delivery of water is controlled by means of a
pressure switch which senses when the analyzer demands water.
During periods of non-use the unit will automatically operate in
intermittent recirculation mode to maintain water purity with
maximum efficiency.

5. INSTALLATION INSTRUCTIONS
5.1 Unpacking the MEDICA-R 7/15 US
The following items should be supplied with your MEDICA-R 7/15 US:
1. MEDICA-R 7/15 US unit.
2. Cartridge pack LC141
3. By-pass block fitted in the unit
4. Installation kit LA637
5. Operator manual
6. Mains lead
7. CTI Tablets
5.2 Positioning the MEDICA-R 7/15 US
Before commencing with installation and operation of the
MEDICA-R 7/15 US system, please read and observe the following
points.
Environment
The system should be installed on a flat, level surface, in a
clean, dry environment. The system 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 the system 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.

ELGA MEDICA-R 7/15 US Operator Manual
MEDICA-R 7/15 US Version 2 –10/15 Page 13
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-R 7/15
US 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).
