1. Locate the length of .95 cm (3/8") O.D. tubing provided with a quick
disconnect insert on one end and a .95 cm (3/8") O.D. X .64 cm
(1/4") NPT tubing adapter on the other.
2. Install the tubing adapter onto your incoming water line. Refer to
tubing installation. A customer supplied shut-off valve is recommended
be installed in your feed water line. The quick disconnect insert will be
inserted into the feed water inlet on the lower left corner in the rear of
the EASYpure RODI during the Initial Operation.
Warning This device is to be used with water feeds only. Cleaning agents
must be used in compliance with instructions in this manual. Failure to
comply with the above could result in explosion and personal injury.
Note Ensure the tubing has no kinks that could restrict water flow.
The RO reject and flush water is sent to drain through this connection.
Refer to Figures 5-10 and 5-11 on the following page.
1. Locate the drain water tubing. This is the 1/4" O.D. tubing that is
approximately 6 ft. long with a 1/4" O.D. x 1/4" N.P.T. tubing adapter
on one end. The atmospheric drain fitting is located on the lower left
corner in the rear of the EASYpure RODI.
2. Install the tubing adapter into the atmospherically vented drain and
route the tubing to the EASYpure RODI drain connector, ensuring
that there are no kinks
3. Take the tubing end that has no fitting, wet the tube end with water
and insert the tube straight into the unit drain connector until it
bottoms out. Refer to Push-to-Connect Fitting Tubing Installation at
the beginning of this section for more explicit details.
To extend tank overflow tubing to an atmospheric drain, use 1/2" I.D.
tubing and tubing connectors (user supplied) to connect the overflow drain
tubing (lower left corner of the rear of the unit) to an atmospherically
vented sink or floor drain.
