Initial Operation

NOTE

Because of the fragile nature of the macroreticular resin used in the D0835 and D0836

Pretreatment Cartridges, it is possible that shipment may have caused fracturing of some of

the resin particles. Resin fracturing will not degrade cartridge performance. However, it may

reduce system performance as evidenced by premature clogging of the Final Filter. To insure

optimum system performance and to prevent premature filter clogging, it is recommended

that the D0835 and D0836 Pretreatment Cartridge be rinsed to remove any fine particles.

Install only the Pretreatment Cartridge in the first canister and run water to drain for ten

minutes.

Install the cartridges as follows:

(Refer to TABLE 2 for correct left to right cartridge sequence.)

A. Remove the protective plastic bag from the cartridges.

B. Install D0835 or D0836 pretreatment cartridge into canister #1. Ensure the small hole is on the top and

the larger hole is on the bottom.

NOTE

Check to be sure O-rings are in place in the canister and inside the head and are not damaged

prior to installation. Do not install the remaining cartridges and final filter at this time.

C. Install the canister, including cartridge on head #1 (closest to pump cabinet).
