Feed Water Inlet Connection
This is the connection from the users feed water
supply line. This line is connected to the bypass
solenoid.
Permeate Outlet Connection
This is the connection to the users equipment.
When RO water is available, it is pressurized by
the RO Permeate Pump. If water is not available,
Inlet feed water is provided bypass solenoid
valve.
Permeate Reservoir
This is the sump which houses the three float
switches, high level, mid level and low level
floats. Permeate water generated by the RO
membrane is stored in this sump for use by the
user.
System Switch - SW1
This is a switch located on the outside of the
IP65 electrical box.
RO Production Level Jumper - J1
This is a jumper located on the inside of the
electrical enclosure on the circuit board itself. If
the jumper is made across the contacts then the
logic will use the high level float as the point to
begin making RO water to fill the RO Permeate
Reservoir. If the jumper is not made across the
contacts then the logic will use the mid level
float as the point to begin making RO water to
fill the RO Permeate Reservoir.
System Selection Jumper - J2 & J3
These are two jumpers located on the inside
of the electrical enclosure, on the circuit board
itself. There are 4 system varieties. Each system
has a dierent minimum and maximum RO
production set point for the change membrane
alarm and a dierent volume setting used in the
calculation of RO production rate. This allows
for the greater systems to have a larger volume
between the mid and high level compensating
for the larger RO permeate reservoirs. It also
enables a set distance between the high and
mid float for standardisation.
