2.3. Plan Your Water System
1. Using a Pressure Storage Tank and Pressure Switch
Your RO system will produce permeate (product water) at a pressure capable of pressurizing a
bladder tank, though tank recovery time will be limited by the production rate of the membrane(s).
Rates of water production for Vectapure™ RSR systems are, at maximum (feed water @<1000
TDS):
RSR1200
0.8 USG/min. (3.0 liters/min.)
RSR2400
1.6 USG/min. (6.0 liters/min.)
For many systems, this rate of recovery will be insufficient in periods of peak usage. It will be
necessary for you to provide product water storage in a non-pressurized tank from which you may
re-pressurize the water for delivery to your appliances or plumbing system.
If a pressure tank and pressure switch is used, be sure that the pressure switch is capable of carrying
the full load amperage of the pump motor. For reference, the motor full load amperages are:
120VAC
RSR1200
15 A
RSR2400
15 A
Consult your electrician to determine the proper sized breaker for your installation. Other motor
voltages are available as a factory option. Consult with your dealer for availability and pricing.
!
ALWAYS ALLOW A NEW SOFTENER INSTALLED TO PRE-TREAT AN RO SYSTEM TO START
ON THE BACKWASH/REGENERATION/RINSE CYCLE. OPERATE THE SOFTENER OFF-LINE
UNTIL WATER RUNS CLEAR BEFORE USING IT TO PROVIDE RO FEED WATER. THIS
PROCEDURE ALSO APPLIES TO NEW RESIN BED INSTALLATIONS. COLOUR THROW
FROM NEW RESIN BEDS MAY DAMAGE OR FOUL RO MEMBRANES.
!
WATERITE DOES NOT RECOMMEND THE USE OF A GRANULAR CARBON CARTRIDGE IN
THE PRE-TREATMENT FILTER HOUSINGS SUPPLIED, FOR THE PRIMARY REDUCTION OF
CHLORINE. IT WILL REQUIRE REPLACEMENT TOO OFTEN, LIMIT FLOW RATES AND
LIKELY LEAD TO CHLORINE BREAKTHROUGH TO THE MEMBRANE ELEMENT. WE
RECOMMEND THAT THIS HOUSING BE RESERVED FOR 5-MICRON OR 1-MICRON
SEDIMENT CARTRIDGES, FOR THE REDUCTION OF SUSPENDED PARTICULATE.
!
IF THE SYSTEM IS CONNECTED DIRECTLY TO A PRESSURE TANK, MAKE SURE THAT A
CHECK VALVE IS INSTALLED ON THE PRODUCT WATER LINE BETWEEN THE MACHINE
OUTLET AND THE PLUMBING SYSTEM PRESSURE SWITCH, TO ELIMINATE
BACKPRESSURE ON THE MEMBRANE(S). FAILURE TO DO SO WILL CAUSE PERMANENT
DAMAGE TO THE RO MEMBRANE(S).
