REVERSE OSMOSIS SET -UP SPECIFICATIONS
Inlet Water Supply
Inlet Pipe Size Should Never Be Smaller Than Equipment Inlet.
This is the inlet to the pre-filter. Sizing can range from ½” to 3” depending on each piece of equipment. General sizing
is as follows:
CP Series: 150-800GPD – ½”
WMXL / VXL / HXL Series: 1500-4000 GPD – ¾”
WMXL / VXL / HXL Series: 4500-10000 GPD – 1”
VXL / HXL Series: 10000-12000 – 1 ½”
HXL Series: 12000-18000 GPD – (2) 1 ½”
HXXL Series: 10500-24000 – (2) 1 ½”
HXXL Series: 26000-28000 GPD – (3) 1 ½”
X Series: 30000 and larger – 2 –3”
Product Water Outlet
On smaller systems without flow meters, the permeate is always the center outlet of membrane housing end cap. On
most other units the permeate outlet is the outlet of the Product Flow Meter. The location of the permeate outlet on
units 30000 GPD or larger is on the right side of the unit.
Waste Water Outlet
On smaller systems without flow meters, reject outlet is the outside port of membrane housing, on opposite end from
the raw water high-pressure feed. On most other units the concentrate outlet is the outlet of the Waste Flow Meter.
The location of the concentrate outlet on units 30000 GPD or larger is on the right side of the unit.
Electrical Connections and Voltages
All CP and WM Series standard units are 110v/60hz. They have a standard 110v 3 prong plug. WMXL, VXL, and
HXL Series units are available in 110v/60hz or 220v/60hz (single or three phase). Please check your electrical
requirements carefully. The equipment warranty does not cover burnouts or damage to electrical components due to
electrical overcharge or incorrect wiring. The 110v/60hz single-phase units have a standard 110v 3 prong plug. Any
220v/hz or 460v/hz units must be hard wired. HXXL Series units are standard 220v/60hz three-phase. X Series units
are available in 220v/60hz three-phase or 460v/60hz three-phase. All 460v/60hz X Series units also require
110v/60hz circuit to be run to the electrical control box. (All systems must be installed to local codes)
System Control Box:
All Water Tec Commercial / Industrial Reverse Osmosis units use 110v control voltage in the electrical control circuit.
All 220v systems are converted internally to 110v. 460v units require 110v and 460v hard wired circuits.
Liquid Level Control Connections and Switch
Wiring connections for the Liquid Level Switch are located directly on top or on the side of the electrical control box.
The two red wires are connected one to one on the wires from the Liquid Level Switch. When the Liquid Level switch
is closed the R.O. will turn on. When the Liquid Level Switch is open the R.O. will shut down.
