Introduction
It is the user’s responsibility to read and to understand the contents of this manual prior to installation and
use of this equipment.
The manual contains the information you will need to install, operate and maintain the E-pure
®
cartridge
deionization system manufactured by Barnstead/Thermolyne Corporation.
The E-pure
®
is designed to produce Type 1 reagent grade water equal to or exceeding standards
established by ASTM, CAP and NCCLS.
Careful attention to the following instructions will assure that the E-pure
®
runs properly and produces
water to specification.
Unpacking Instructions
Unpack the E-pure
®
carefully. Ensure that all components are removed prior to discarding packaging. The
wall bracket can be removed and used as a mounting template.
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
®
, Barnstead encourages the use of our water analysis service to verify feedwater suitability. A
sample collection kit may be obtained by contacting Barnstead/Thermolyne 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 2 on page 10 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.
On 100 VAC, 115 VAC and 230 VAC models 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.
