OPERATING CONTROLS

A.ON/OFF Switch

ON - Placing the switch in the left position allows the start switch to activate a timed brew cycle for three gallons of tea.

OFF - Placing the switch in the right position stops the brew cycle. Stopping a brew cycle after it has been started will not stop the flow of water into the funnel until the tank syphons down to its proper level. The switch should always be placed in this position after a brew cycle and whenever the brewer is unattended.

B.Start Switch

Starts a brew cycle when the ON/OFF switch is in the "ON" position.

Starts a brew cycle when the UNSWEET/OFF/SWEET switch is in either the "UNSWEET" or "SWEET" position. (Models with Sweetener Only)

C.OFF/SELECTOR Switch (Models with Sweetener Only)

UNSWEET - Placing the switch in the left positional allows the start switch to activate a timed brew cycle for three gallons of tea without sweetener.

OFF - Placing the switch in the middle position stops the brew cycle. Stopping a brew cycle after it has been started will not stop the flow of water into the funnel until the tank syphons down to its proper level. The switch should always be placed in this position after a brew cycle and whenever the brewer is unattended.

SWEET - Placing the switch in the right positional allows the start switch to activate a timed brew cycle for three gallons of tea with sweetener.

CLEANING

CAUTION - CLEAN AND SANITIZE YOUR ICED TEA BREWER DAILY

1.Remove and thoroughly clean the entire brew funnel. The funnel tip and screen must be free from any tea particles or residue. Reassemble the funnel.

2.Unplug the brewer. Remove and thoroughly rinse the sprayhead. The holes must be open and clear of any mineral deposits. Wipe the sprayhead panel clean with a damp cloth.

3.Insert the deliming spring into the sprayhead fitting until no more than one inch is visible and move it in and out 5 or 6 times. Reattach the sprayhead.

4.Wash the entire outside surface of the brewer with a clean damp cloth.

CAUTION - DO NOT KEEP BREWED ICED TEA OVERNIGHT. THE SERVER MUST BE CLEANED DAILY.

AUTO SWEETENER CLEANING

1.Remove the connector off of the bag in a box.

2.Place the end in a bucket of hot water (120°-130°F)

3.Place an empty reservoir on the base under the dilution nozzle.

4.Set the selector switch to the "Sweetened" setting.

5.Press and release the "Start" switch.

6.Run three brew cycles in a row, emptying the reservoir after each cycle.

7.When the three cycles have been completed, hook the connector back up to the bag in a box system. (This will keep buildup from occurring in the system.)

This procedure should be performed weekly or as needed to keep the system clear.
