E-pure® Water Purification 1-1Thermo Scientific
Section 1 Safety Information
Your Thermo Scientific E-pure® Water Purification unit 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. 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.
Wa nings
To avoid electrical shock, always:
1. Use a properly grounded electrical outlet of correct voltage and current
handling capacity.
2. Ensure that the equipment is connected to electrical service according
to local and national electrical codes. Failure to properly connect may
create a fire or shock hazard.
4. Do not mount your E-pure directly over equipment that requires
electrical service. Routine maintenance of this unit may involve water
spillage and subsequent electrical shock hazard, if improperly located.
5. For continued protection against possible hazard, replace fuses with the
same type and rating of fuse.
5. Disconnect power supply from equipment prior to servicing.

Section 1
Safety Information
To avoid pe sonal inju y:
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. This device is to be used with water feeds only. Sanitizing/cleaning
agents must be used in compliance with instructions in this manual.
Failure to comply could result in explosion and personal injury.
3. Avoid splashing disinfectant solution on clothing or skin. Ensure all
piping connections are tight to avoid leakage of chemicals. Always
depressurize chemical lines before disassembly. Ensure adequate
ventilation. Follow carefully the manufacturer’s safety instructions on
labels of chemical containers and material data sheets.
4. Depressurize the system prior to attempting to remove the canisters.
5. Refer servicing to qualified personnel.

Introduction

E-pure® Water Purification 4-1Thermo Scientific
Section 4 Precautions Before
Installation
The E-pure deionization system can be used on pretreated or high quality
tap water. Some municipal tap water supplies contain a very high
concentration of suspended particles, colloids, and dissolved organic and
inorganic materials that should be removed by pretreatment before the
water is processed by the E-pure. The 4-module unit is typically used with
tap water. The 3-module unit is typically used with water pretreated by
reverse osmosis, distillation or deionization. If you plan to use a tap water
feed for your E-pure, we encourage the use of our water analysis service to
verify feedwater suitability. A sample collection kit may be obtained by
contacting Technical Services or your preferred laboratory supply dealer.
The E-pure requires expendable pretreatment and deionization cartridges
and final filters which are not supplied with the unit and must be
purchased separately. These expendables are available as individual
components or in Expendable Kits. See Table 4-2 for kit listings.
Your E-pure is supplied with a pre-wired jumper in the “pump interlock”
connector. Installation of options D0603, D0606 (Float Switch) or D2706
(Pressure Switch) require removal of this jumper plug. DO NOT discard
this plug, it will be needed for certain maintenance operations.
A power cord is provided with a plug to be connected to a standard
grounded electrical outlet. The power cord on E-pure is color coded to
CEE* specifications. (Table 4-1).

Section 5 Mounting and Utility
Screws and fasteners required for wall mounting are not supplied with the
unit. The recommended dimensions for mounting hardware to support
your E-pure are:
• Body Diameter, 1/4” maximum
• Head Diameter, 3/8” maximum
• Length, 1” typical
The E-pure should be mounted at a convenient height for routine
operation. Adequate front access will be required for cartridge or filter
exchange and reading of the resistivity meter, if used. The following
clearances are necessary:
Left and right side clearance - 6” minimum
Free space below canisters - 10” minimum
Free space above center of wall bracket - 13” minimum
The E-pure comes completely assembled. The only requirements are to
secure the unit to the wall and have a source of feedwater and electrical
service nearby.
The E-pure comes complete with a 6 (six) foot power cord that must be
plugged into a suitable outlet. See specification plate for electrical
requirements.
Warning Do not mount E-pure directly over equipment that requires
electrical service. Routine maintenance of this unit may involve water
spillage and subsequent electrical shock hazard if improperly located. s
Warning Ensure that the equipment is connected to electrical service
according to local and national electrical codes. Failure to properly connect
may create a fire or shock hazard. s
Warning This device is to be used with water feeds only.
Sanitizing/cleaning agents must be used in compliance with instructions in
this manual. Failure to comply could result in explosion and personal
injury. s

Section 5
ounting and Utility
Caution Do not connect unit to electrical service until so instructed. s
Caution Wall composition, condition and construction, as well as fastener
type must be considered when mounting this unit. The mounting surface
and fasteners selected must be capable of supporting a minimum of 145
pounds. Inadequate support and/or fastener may result in damage to
mounting surface and/or equipment. If you are unsure of mounting surface
composition, condition and construction or correct fasteners, consult your
building maintenance group or contractor.
The E-pure must be mounted at a level with easy access to controls and
valves and where the digital display can be read.
1. Remove the wall bracket from the unit by removing the two screws
located at the left and right hand bottom portion of the wall bracket.
See E-pure Exploded View drawing toward the end of this manual, for
location.
2. Secure the wall bracket to the wall using suitable fasteners.
3. Carefully remove the canisters from the heads by depressing the thumb
lever and rotating 1/4 turn from right to left.
4. Mount the E-pure on the wall bracket by lifting unit and fitting
mounting pins securely on to the corresponding holes on the bracket.
Replace the two screws that were removed in Step 1.
5. Ten feet of 3/8" OD tubing and a 3/8" OD x 1/4" NPT tubing
adapter is supplied with your unit for feed water connections.
6. Wrap 1-1/2 - 2 turns PTFE tape to 3/8" OD x 1/4" NPT adapter and
secure to feedwater piping.
7. Secure tubing to E-pure feedwater connection. See tubing connector
installation Figure 5-1.

Caution It does not require much force to effect a water tight seal. Over
tightening of the adapter will create damage and subsequent leakage. s
Note It is recommended that the customer supply a feedwater shut off
valve to interrupt water to the unit when cartridge replacement is
necessary.
Note Do not tighten tube fitting hex nut with a wrench. Tight
connections can be made by hand.
1. Completely disassemble the fitting. Refer to Figure 5-1 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 back up ring in the hex nut in the order and
orientation shown in Figure 5-1. Thread the nut onto the connector.
DO NOT use the O - ring at this time.
4. Push the tubing through the nut until it bottoms out in the connector.
5. Remove the adapter nut and tubing. Place the O-ring over the tubing.
Be careful not to push the backing ring or grab ring further back on
the tubing when installing the O-ring.
6. Install the hex nut on the connector and hand-tighten.
7. Repeat above steps when securing tubing to the E-pure.
