INSTALLATION
General: The RO system should be located indoors in a location protected from excessive heat, cold,
or dust. The system must sit on a level floor and space in front and to both sides should be provided for
service. See outline dimensions in Figure 6.
Electrical: The system requires a source of grounded 220 volt, 60 Hertz ("H" model is 50 Hertz), 1
phase power. The power conduit should enter the rear of the system at the nominal 3/4" conduit hole
(1.06 inches actual diameter). In addition to the two power wires, a good ground wire of the same size
must be connected.
The electrical power connects to a two position terminal block inside the right hand side of the system.
The control box cover, held on by eight 6-32 Phillips screws must be removed. Then undo the two wing
nuts to remove the clear high voltage guard. Make certain that the screw terminals that clamp the
power wires are very tight. Connect the ground wire to the screw stud where the other green ground
wires are attached.
Drain: Waste water exits the RO system through a rubber sleeve connection that fits nominal 1 & 1/2
inch drain pipe (actual OD is 1.9 inches). The rubber sleeve connection tightens with a hex head (5/16"
or 8 mm across flats) screw on the SS band clamp. Use a long socket extension or a nut driver to
loosen the clamp. Remove the existing stub pipe placed for shipping.
The drain pipe can be run level or with a slight downward pitch to a "U" trap and into a sanitary sewer
line.
Feed Water: Presoftened and dechlorinated feed water enters the system at a 3/4" FPT plastic fitting
on the left side. Do not undersize the feed water piping to this point. A minimum pipe/tube/hose ID of
3/4 inch is recommended.
If the seal cone union provided is used, no TFE tape is required on the inlet fitting. However, it is
mandatory that the 3/4" MPT user connection have a smooth and beveled ID to match the seal cone.
Good installation practice allows for the inlet piping to be easily removed if service and access is
required. In general, a flexible inlet connection that does not transmit constant strain on the pipe joint is
preferred. If rigid piping is used, positioning should be exact and threaded unions should be used to
allow disassembly and correction of potential pipe thread leaks.
Product Water Outlet: The product output flow from the system exits at a 3/4" MPT nipple. The same
piping considerations expressed for the feed water connection above also apply to this fitting.
Product Water Return: Unused product water returns to the RO system at this 3/4" MPT connection. It
is recommended that initially this connection not be made until any piping debris in the distribution loop
is flushed to drain. If the product line is run dead ended, without a return from the loop, a bypass
assembly from product outlet to product return must be used.
