Blending Valve Adjustment Instructions:
IMPORTANT NOTES:
• Typical TDS (Total Dissolved Solids) values for coffee are 80-200 ppm (parts per million) and occasionally lower for espresso, depending
upon taste preference. Typical TDS valves for steam and combi ovens are less than 50ppm.
•
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.
•
To set blending valve use TDS monitor set in the "out" position.
1. Open shut off valve in blending line.
2. Allow unit to run and fi ll tank for 5 min.
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 (See Figure 5 item #2 below). The valve should be opened intermittently a quarter turn 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.
(See Figure 5-item #2 below)
4. Lock the blending valve using the lock nut.
5. After TDS is set, drain RO tank. System is now ready for use.
IMPORTANT NOTE:
The TDS Monitor is push-button operated and requires two (2) 357A batteries. (Included in TDS meter)
Membrane Flushing Instructions:
1. Open pressure tank sample valve and empty tank to drain.
2. Flush system for at least 24 hours.
3. Close tank sample valve
Storage Tank and RO System Sanitizing Instructions:
Sanitizing the storage tank requires:
• Common household bleach (5.25% non-scented) or sanitizing agent
• Eye dropper or plastic oral syringe
a.) Disconnect the 1/2” line from marked”Tank Outlet” to pressure tank.
b.) Insert 15ml (0.5 ounces) 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.
