Original Instructions
Setting Up the WaterPro RO System
Unfold the installation template included and follow the instructions to mount the WaterPro RO
System on a suitable wall.
If the optional Wall Mounting Panel, Support Stand or optional WaterPro RO/PS Mobile Stand has
been purchased, discard the templates and follow instructions provided with the option.
When installing the WaterPro RO the unit should be lifted in place and supported from the bottom
by two people on both sides of the unit.
Feed-water and Drain Connection
The supplied feed water is 3/8" OD (0.95 cm) rigid plastic tubing. If more tubing is required, refer
to Replacement Parts section in this manual. The tubing is inserted into the inlet port identified as
#14 on page 27. At a convenient spot in the supply line, a valve should be installed so the
WaterPro RO may be isolated from the feed water supply when required. Line pressure should not
exceed 100 psi (7 Bar). Feed water line must be able to supply1.6 gal/min at a minimum pressure
of 30 psi or pump cycling will occur.
To connect the feed water supply to the inlet port, cut the tube square, check for burrs, and insert
into the inlet water fitting as explained in the Tubing Installation section below.
There are two drain lines. One is from the tank overflow and the other is from the RO for reject
water, route both drain lines to a drain which is able to handle a minimum of 2-gal/min water flow.
Tubing Installation
The tubing connectors used in the WaterPro RO have been selected for their dependability and
ease of installation. A detailed drawing of a typical connection is shown in Figure 3.
For flexible tubing, be sure to insert a tube support into the end of the tubing. Rigid tubing does
not require the use of a tube support.
