Specifications
A Watts Pure Water Series PWR4011 reverse osmosis system
shall be installed to provide reverse osmosis quality water. The
RO system shall be installed after a Series PWS water softener
so that scale forming calcium and magnesium hardness cannot
scale the RO membrane(s). Series PWC backwashing carbon
filter shall be installed on the RO feed water line to remove
chlorine and prevent membrane degradation due to chlorine
attack. Series PWM backwashing sediment filter shall also be
installed on the RO feed water line to reduce the silt density
index of the water to prevent particulate fouling of the RO
membrane(s).
The RO system shall be a low-energy type unit complete with
permeate and reject water flow meters, pre-filter inlet/outlet
and membrane feed water pressure gauges, 316L stainless
steel membrane housings, automatic inlet solenoid valve, stain-
less steel high-pressure piping, low feed water pressure switch,
reject and recycle valves, storage tank level and pretreatment
interlock inputs, micro electronic controller, multistage centrifu-
gal high-pressure pump, and all other components necessary
for proper operation. The system shall be a wall mount design.
The RO permeate water shall be collected in an atmospheric
storage tank with the tank level controlled by an electronic level
float. The RO shall be equipped with inputs for the tank level
float as well as pretreatment interlock to shut the RO system
down in the event the pretreatment begins a backwash cycle.
Electrical requirements are 230 volt 60 hertz single phase. A
local drain is required to accept drain water from the system.
The feed water pressure must not fall below 20psi. The feed
water temperature must not fall below 35°F or exceed 100°F
(2° - 38°C).
The system shall produce reverse osmosis quality water with
95 percent minimum average ionic rejection of total dissolved
solids when operated within the manufacturer’s operational
specifications.
Feed Water Guidelines

Hardness (maximum) . . . . . . . . . Less than 1 grain per gallon as
CaCO3 (Softened) or anti scale

(contact your Watts representative)
Feed Water Pressure (minimum) . 20psi
Temperature . . . . . . . . . . . . . . . 35 - 100°F (2 - 38°C)
Free Chlorine (maximum) . . . . . . None Allowed

Notes:
• For all other guideline information please contact your Watts represen-
tative.
• Published maximum production rates are based on a feed water of
77°F, SDI of less than 3, 1000 ppm TDS, and pH 8.
• Individual membrane productivity may vary (± 15%). May be operated
on other feed waters with reduced capacity.
• Percent rejection is based on membrane manufacturer’s specifications;
overall system percent rejection may be less.
