Hint:
Use the TO flush valve for a source of water to fill the storage tank after the level
switch stops the flow of water.
3. The storage tank requires complete draining at this time. This can be accomplished one of
two ways, based on what steps were done in step 1 above. They are:
a) Open the valve on the storage tank drain connection and allow the storage tank to
drain.
b) Connect the re-pressurization pump to a 115-Volt receptacle. The re-pressurization
pump will pump the water through the product water tubing/piping and to the drain.
Allow the pump to run until the storage tank is empty. Disconnect the re-
pressurization pump from the 115-Volt receptacle.
Upon completion of the storage tank drain down, refill the storage tank a second time by re-
connecting the 24 VAC transformer to a 115-Volt receptacle and opening the filtered water
blend valve fully. Allow the storage tank to fill until the level switch stops the flow of water.
Disconnect the 24 VAC transformer from the 115-Volt receptacle. Drain the storage tank a
second time using one of the procedures outlined above. Repeat this process until no
residual chlorine odor is detected. Re-install the drain plug or re-connect the equipment
being serviced as required.
4. Connect the 24 VAC transformer to a 115-Volt receptacle. The system will begin filling the
storage tank with product water. Close the filter water blend valve at this time.
5. Certain applications require the product water to contain a range of TDS greater than what
an RO system normally produces. In those cases, a filtered water blend valve has been
provided to blend in filtered (not RO treated) water to attain a specific TDS range. Rotate the
handle on the product water 3-way sample valve so it is pointing towards the drain
connection (front of unit). Using a TDS meter, measure the TDS the RO system is currently
producing. If the TDS is too low, open the filtered water blend valve as required until some
additional flow is observed in the product water sample. Re-check the TDS level present.
Adjust the filtered water blend valve as required to attain a TDS level in the middle of the
TDS range specified.
6. Rotate the handle on the product water 3-way sample valve so it is pointing towards the
storage tank connection (rear of unit).
7. Open the product water shut-off valve.
8. Connect the re-pressurization pump to a 115-Volt receptacle.
9. Install the AAA batteries into the gallon/calendar Monitor. Follow the instructions provided
with the monitor to program the unit volume and calendar settings.
10. During normal operation, make sure the system valves are in the following positions:
a.
System inlet and outlet valves – open
b.
Sample port/flushing valves – closed
c.
Product water 3-way sample valve – handle pointing towards the storage tank
connection (rear of unit).
11. Once the system been started-up initially, it is a good idea to measure the outlet water flow
rate and quality to check on the system performance. The initial values should be recorded
for future comparison to detect any changes in performance. See the Maintenance section
of this manual for detailed procedures.
