EASYpure RoDi 1-1Thermo Scientific
Section 1 Safety Information
Your Thermo Scientific EASYpure™ RoDi has been designed with
function, reliability, and safety in mind. It is the user’s responsibility to
install it in conformance with local electrical codes.
This manual contains important operating and safety information. The
user must carefully read and understand the contents of this manual prior
to the use of this equipment. For safe operation, pay attention to Notes,
Cautions, and Warnings throughout the manual.
Water purification technology employs one or more of the following:
chemicals, electrical devices, mercury vapor lamps, steam and heated
vessels. Care should be taken when installing, operating or servicing
Thermo Scientific products. The specific safety notes pertinent to this
product are listed below.
Warnings
To avoid electrical shock:
1. Use a properly grounded electrical outlet of correct voltage and current
handling capacity.
2. Do not mount your EASYpure RoDi directly over equipment that
requires electrical service. Routine maintenance of this unit may
involve water spillage and subsequent electrical shock hazard, if
improperly located.
3. Replace fuses with those of the same type and rating.
4. Do not disassemble water lines or remove cartrdges where spilled water
could contact equipment that requires electrical service. Electrical
shock hazard could result.
5. Power unit Off before plugging in, or unplugging unit.
6. Disconnect from the power supply prior to maintenance and servicing.

Section 1
Safety Information
To avoid personal injury:
1. Do not use in the presence of flammable or combustible materials;
fire or explosion may result. This device contains components which
may ignite such materials.
2. Do not use in the presence of highly corrosive substances such as
bleach or acid baths; fire may result.
3. This device is to be used with water feeds only. Cleaning agents must
be used in compliance with instructions in this manual. Failure to
comply with the above could result in explosion and personal injury.
4. Avoid splashing cleaning solutions on clothing or skin.
5. Ensure all piping connections are tight to avoid chemical leakage.
6. Ensure adequate ventilation.
7. Carefully follow manufacturerʼs safety instructions on labels of
chemical containers and material safety data sheets.
8. Depressurize system prior to opening cartridge access door or
removing top cover.
9. This unit is equipped with an ultraviolet lamp. Ultraviolet radiation is
harmful to the eyes and skin. Do not observe the lamp directly while
it is illuminated.
10. Do not operate unit with door open. Inlet pressure may force RO
prefilter out of position.
11. Refer servicing to qualified personnel.

EASYpure RoDi 2-1Thermo Scientific
Section 2 Introduction
The Barnstead EASYpure RODI is a tap-fed water purification system
designed to be simple to use and to provide reagent grade water that
exceeds ASTM, Type I, and NCCLS/CAP Type I standards. It uses a thin
film composite reverse osmosis membrane with one stage of pretreatment
to produce RO water that is then polished using a two-stage deionization
process combined with UV oxidation and a 0.2 micron final filter.
The % rejection between incoming and reverse osmosis product water is
monitored and an indication is provided to the user if the RO water
quality is unacceptable. RO membrane pressure is provided by a pressure
gauge located on the right side of the unit. The DI water resistivity is
continuously sensed by a resistivity cell and displayed on a digital display
in megohms-cm.
RO operation is automatic and works independently of the DI system to
fill the EASYpure RODIʼs self-contained 6.5-liter reservoir as determined
via the position of 3 floats in the reservoir.
The EASYpure RODI is not shipped with a reverse osmosis membrane,
cartridges or final filter. These must be ordered separately. The start-up kit
containing these components can be ordered from Technical Services.
The EASYpure RODI is designed to be a bench mounted unit. If wall
mounting is required, refer to “Wall Mounting” on Section 5.

Section 5
Installation
The following instructions will apply when you need to attach a piece of
tubing to your EASYpure RODI during installation, unless otherwise
noted in the installation instructions. To make tubing connections:
1. Make sure the tubing is cut off reasonably square and that no plastic
burrs or ridges are present.
2. Mark an insertion length of 11/16” from end of tube (Figure 5-1).
3. Wet the tube end with water and insert the tube straight into the
fitting until it bottoms out on the interior shoulder and the insertion
mark is no longer visible.
Note For easier insertion, wet the end of the tubing with water. s
1. Using the tool provided (Figure 5-2), push the collet toward the body
while pulling on the tubing to release the tube.
1. Completely disassemble the fitting. Refer to Figure 5-3 to familiarize
yourself with the names of the component parts.
2. Make sure the tubing is cut off reasonably square and that no plastic
burrs or ridges are present.
3. Place the grab ring and backup ring in the hex nut in the order and
orientation shown in Figure 5-3. Thread the nut onto the adapter. DO
NOT use the o-ring at this time.
4. Push the tubing through the nut until it bottoms out in the adapter.
5. Remove the adapter nut and tubing. Place the o-ring over the tubing.
Be careful not to push the backup ring or grab ring further back on the
tubing when installing the o-ring.

6. Install the hex nut on the adapter and hand-tighten.
Caution Do not tighten tube fitting hex nut with a wrench. Tight
connections can be easily made by hand. s
These fittings are found on the water inlet. See Figure 5-4.
Note The quick disconnect fittings contain valves and if not properly
inserted, water will not flow. s
To insert the inlet tubing:
1. Press on the metal thumbpad on the unit to ensure the fitting is open.
2. Install the coupling insert into the coupling body until a click is heard.
Gently pull on the tubing to verify it is secure.
3. To remove, press the metal thumbpad to release and pull coupling
insert out.
