Mounting the E-pure
®
The E-pure® must be mounted at a level where there can be easy access to controls and valves and
where the digital display can be read.
A. 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 Figure D for location)
B. Secure the wall bracket to the wall using suitable fasteners.
C. Carefully remove the canisters from the heads by depressing the thumb lever and rotating 1/4 turn
from right to left.
D. 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 A.
E. 10 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.
F. Wrap 1-1/2 - 2 turns Teflon® tape to 3/8" OD x 1/4" NPT adapter and secure to feedwater piping.
CAUTION
It does not require much force to effect a water tight seal. Overtightening of the adapter
will create damage and subsequent leakage.
NOTE
It is recommended that the customer supply a feedwater shut off valve to interrupt water to
the unit when cartridge replacement is necessary.
G. Secure tubing to E-pure
®
feedwater connection. (See tubing connector installation Figure A.)
Tubing Connector Installation
A. Completely disassemble the fitting. Refer to Figure A to familiarize yourself with the names of the
component parts.
B. Make sure the tubing is cut off reasonably square and that no plastic burrs or ridges are present.
C. Place the grab ring and back up ring in the hex nut in the order and orientation shown in Figure A.
Thread the nut onto the connector. DO NOT use the O - ring at this time.
D. Push the tubing through the nut until it bottoms out in the connector.
E. 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.
F. Install the hex nut on the connector and hand tighten.
G. Repeat above steps when securing tubing to the E-pure
®
.
CAUTION
Do not tighten tube fitting hex nut with a wrench. Tight connections can be made by
hand.
