above, then check for a proper operation
of the High Pressure Pump Contactor. To
deactivate the contactor, press the “Stop”
switch twice. To activate the contactor
again press “Start” switch.
6. If the contactor is mechanically operating,
but no voltage present at the motor
terminal (step 3 above), then the contactor
may be at fault.
7. If the contactor does not operate
mechanically, then measure DC voltage
between A1 and A2 terminals. It should
read 12V DC when activated.
8. If the contactor gets 12V DC, but
inoperative, then its coil may be open.
Replace the contactor.
9. If 12V DC is not present when the High
Pressure Pump is activated, trace orange
and orange/black wires to TB-2 and
measure the DC voltage at the terminals.
It should read 12V when activated.
10. If 12V DC is not present at the High
Pressure Pump terminals, then
disassemble Controller Enclosure and
open the shell by removing 4 screws. This
exposes the main controller circuit board.
If the voltage is present but the High Pressure
Pump Contactor does not activate, then check
cable connections between the Controller
Enclosure and Main Power Enclosure.
e) Salinity Meter registers potable water, but the
product water has a definite salt taste.
There is a blockage in the Brine Discharge Line
causing Brine Discharge Water intrusion into
the 3-way Product Water Diversion Valve. The
3-way Product Water Diversion Valve Seats
have been tampered with and require proper
adjustment.
The Salinity Probe may be dirty
and requires cleaning
f) Fresh Water Flush Adjustment
1. Put the system in stand-by pressing
the FRESH WATER FLUSH switch
activates the Automatic Fresh Water
Flush operation and subsequent 7 day
repeat cycle. The FWF duration must be
set properly in order to enable the FWF
function (see calibration mode below).
2. When the FWF duration is properly set,
the system automatically goes into the
FWF mode to perform the operation every
time the system is in the normal operating
mode and the STOP switch is pressed once.
3. To stop the FWF operation the STOP
switch can be pressed anytime the
system is performing the Fresh Water
Flush operation.
4. After the Fresh Water Flush completes
the system goes into a 7 day stand-by
mode. The Fresh Water Flush cycle
will repeat every 7 days until the STOP
switch is pressed.
5. If a low level switch is installed and the
water tank low level condition is detected
the FWF does not start and reverts to the
system stand-by mode.
6. If the power is lost during the FWF
operation the FWF operation restarts
when the power is restored.
7. If the power is lost during the 7-day
waiting period the waiting period
resumes counting from the point of the
power loss when the power is restored.
Fresh Water Flush Calibration:
1. Pressing the FRESH WATER FLUSH
switch allows the Fresh Water Flush time
duration to be calibrated.
2. Adjust R71 (FWF) for desired duration of
the Fresh Water Flush operation. Note, on
the average the flow rate of fresh water
through the System during the Fresh
Water Flush Cycle will be approximately
.75 U.S. Gallons Per minute or 2.8 Liters
Per Minute.
A system equipped with only 10 inch pre
filters will require about 5 U.S. Gallons or
6 to 7 minutes duration.
A system equipped with Commercial
Prefilter and Oil Water Separator
will require about 8 U.S. Gallons or
10 minutes duration.
A system equipped with Commercial
Prefilter, Oil Water Separator, and Multi
Media Filter will require about 10 U.S.
Gallons or 12 to 14 minutes duration.
