FLOW CONTROL
AND
SCREEN
The flow
control
is vital for proper
operation
of the
RO membrane
cartridge.
The control
keeps
water
flow through
the membrane
at the needed
rate to ob-
tain the best quality
product
water.
Whenever
servicing
the RO system,
check
the flow
control
to be sure the small
hole
through
it is clean
and unrestricted.
Also check and clean or replace
the
cone-shaped
screen
in front
of the control.
The RO
membrane
cannot
discharge
minerals
and
impuri-
ties to the drain if the flow control
plugs
with foreign
material.
If this happens,
it only takes a short time for
the membrane
to foul and become
useless.
