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).
