System Start Up
1. Turn ON the feedwater supply by plugging system into electrical outlet.
2. Press reset button on top of electrical enclosure (see Figure 4).
3. Open Pre-filter flush valve to vent air from system and flush for five (5) minutes.
4. Close flush valve.
5. Complete blending valve adjustment procedure below.
6. Allow tank to fill until the RO unit turns OFF on full tank (see chart).
7. Turn OFF the feedwater supply by unplugging system from electrical outlet.
8. Open pressure tank sample valve and empty tank to drain. Close tank sample valve.
9.
Sanitize the Storage Tank and Filtration System as per instructions below
Sanitizing the storage tank generally requires:
•Commonhouseholdbleach(5.25%non-scented)orsanitizingagent
•Eyedropperorplasticoralsyringe
a.) Disconnect the 1/2” line from marked”Tank Outlet”
to pressure tank.
b.) Insert 1 tablespoon of bleach or sanitizing agent into 1/2” line to pressure tank.
c.) Reconnect the 1/2” line to pressure tank.
d.) Turn ON the feedwater supply by plugging system into electrical outlet.
e.) Wait 4-5 hours.
f.) Open pressure tank sample valve and empty tank to drain.
g.) Sanitizing is now complete.
h) If there is any residual chlorine/bleach taste in the next tank full, drain tank completely a second time.
10. Allow tank to fill again.
System is now ready for use.

Blending Valve Adjustment Procedure
IMPORTANT NOTES:
•TypicalTDS(TotalDissolvedSolids)valuesforcoffeeare80-200ppmandoccasionallylowerforespresso,dependingupontaste
preference.
•
The blending valve should be set at start-up and checked periodically, for example when changing filter cartridges. The valve is a
precision metering valve, that may be locked by tightening lock nut.
•Inordertosettheblendingvalve,bypassvalvemustbeclosed.ThesystemTDSoutputcanbemeasuredviatheTDSmeterposition
“out”. The system TDS input can be measured via the TDS meter position “in”.
1. Close the outlet shut-off valve to downstream equipment and the tank shut-off valve and open the RO sample valve at the tank.
3. To adjust blending, rotate the blending valve to the left (counterclockwise) to increase the product water TDS and to the right
(clockwise) to decrease the product water TDS. The valve should be opened intermittently at 1.0 to 1.5 turns at a time. Check the
TDS after each incremental adjustment and again two (2) minutes after the desired TDS value is reached. Re-adjust and check, as needed.
4. Lock the blending valve using the lock nut.
IMPORTANT NOTE: The TDS Meter is push-button operated and requires two (2) 357A batteries. (included in TDS meter)
