SET-UP INSTRUCTIONS
1. Loosen the four slotted screws and remove the
top cover. Remove the heating tank lid.
2. Pour water into the heating tank until the water
level is one to two inches below the siphon
tube. Replace the tank lid.
3. Connect a water line to the inlet valve behind the
machine. Turn on water.
4. Locate the thermostat. Turn the stem of the thermostat clockwise until it stops.
5. Plug in the electrical cord to a 120 VAC, 20 Amp,
outlet. Flip the toggle switch, located behind the
machine, to the ON position. At this time the
READY TO BREW light will be off.

6. Wait about 20-25 minutes for the water to reach
brewing temperature.
7. Because of the siphon system, proper water level in the heating tank must be established:
a. Place iced tea dispenser on the brewer, under the empty brew cone.
b. Press the brew switch.
c. As soon as you see water flowing, switch off the ON/RESET switch.
d. The water level in the heating tank is now correct and the machine is ready to brew.
e. Make sure the READY TO BREW light is on. This indicates the water in the heating tank is at
operating temperature.
NOTE: These brewers are set at the factory to brew 3 gallons (TCT-35S) or 5 gallons (TCT-35).
8. The dual timer operation and setting: The Concentrate Knob determines the entire
length of brew cycle, while the Dilution Knob establishes the length of each of the
five (5) cold water cycles within the brew cycle in order to reach the correct hot to
cold water ratio.
a. The amount of tea concentrate brewed can be adjusted by the timer
knob marked CONCENTRATE. Use one (1) gallon as the standard setting.
b. The ratio of tea concentrate to cold water can be adjusted by the
timer knob marked DILUTION.
c. The starting ratio will be one gallon concentrate and two gallons of
dillution. The ratio can be adjusted to obtain the desired brew.

BREWING INSTRUCTIONS
1. Once the water in the tank reaches
the proper temperature (200º F),
the READY TO BREW light will
come on.
2. Place filter into filter basket. Pour
leaf tea into basket. Slide brew cone
into brew rails.

3. With an iced tea dispenser in place,
push the brew switch.
Brewed tea will start to fill the tea
dispenser.
Caution: Do not pull out brew cone until it stops dripping
to avoid scalding from hot liquid.
SPECIAL INSTRUCTIONS FOR BREWING
WITH FILTER PACKS
If you will be using tea that is packaged in a filter pack, it is recommended that the
water spreader portion of the two-piece Sprayhead be removed. This will allow for a
single stream of hot water to pour directly onto the tea package. The penetration of
water into the filter will help to increase the extraction from the tea package.
The threaded part of the Sprayhead is tightly fitted to the Spreader section. To
remove, grab the Spreader (with the sprayhead still on the brewer) and pull it firmly
downward. The two pieces will separate, leaving the threaded half still on the
machine.

PROBLEM: No response when Brew Switch is depressed. No hot or cold water dispensed.
POSSIBLE CAUSE

Faulty Brew Timer
WC-655
PROBLEM: No hot water flowing from Sprayhead. Only cold water cycles.
POSSIBLE CAUSE
Faulty Water Inlet
Valve Coil, WC-824
Faulty Brew Timer,
WC-655
Disconnect the water line from the inlet valve and check the water pressure. Reconnect the water line. Replace the filter cartridge and remove any obstruction. Note:
The minimum pressure on the inlet valve should be 20 PSI.
While pressing the Brew Switch, check for continuity between the two side terminals, 4B and 5B. If you do not read 110 - 120V from 5B to L2, the switch is defective. Replace the switch.
a. With a voltmeter, check the incoming power across terminals L1 and L2
(you should read 110 - 120V). If correct, the timer is energized.
b. Check the voltage across terminals S/S and L2 while pushing the brew switch.
At this time the timer should be energizing the coils of the water inlet valves to
open them. You should read 110V to 120V between the terminals of each coil. If
there is no voltage, replace the timer.
With a voltmeter, check for voltage to the valve coil for the HOT water side. If there is
power to the coil and no water is flowing, the valve must be replaced.
With a voltmeter, check the voltage across terminals L2 and HOT terminal (press
brew switch to test). If voltage is not present, timer is faulty.

element
With a voltmeter, check for voltage to the valve coil for the COLD water side. If there
is power to the coil and no water is flowing, the valve must be replaced.
With a voltmeter, check the voltage across terminals L2 and COLD terminal. If
voltage is not present, timer is faulty.
Check to see that the thermostat is turned on. Twist the stem clockwise as far as it
will go.
Read the current with a clamp ammeter on one of the two 14 gauge wires connected
to the element. Turn on the machine. The meter should read approximately 16
amperes. If you cannot get an ampere reading, use a voltmeter to check for voltage
across the heating element terminals. If there are approximately 115 volts, the
element is burned out. Replace elements.

NOTE: On these brewers, the Low Water Cutoff Thermostat, part no. WC-508R, serves to
automatically cut off the power to the heating element in case the water level drops too low. When
the water level is so low that the element is exposed, the very hot temperature will cause the reset
button, on the thermostat, to pop out; thus preventing the heating element from burning out.
When the low water condition has been corrected, push in the red button on the thermostat to reset.
You will know when it has reset by a distinct click.
TCT-35, CLEANING
Regular cleaning of the TCT-35 Iced Tea Brewer is essential in maintaining the best quality iced tea
flavor that the unit is capable of brewing.
1. Wipe any spills, dust or debris from the exterior surfaces with a damp cloth. The outside surfaces
of the TCT-35 should be cleaned with stainless steel polish only, to prevent scratches.
2. Clean the sprayhead and domed area around the sprayhead with a detergent solution and scrub
well to remove residue. Rinse with and clear water. Dry with clean cloth.
3. Remove the wire filter holder from the brew basket and wash both parts with a detergent solution
or put these parts through a dishwasher.
4. Wash the tea container and top cover with a detergent solution. Remove the faucet assembly.
Unscrew the handle assembly from the faucet and remove. Clean the faucet shank with a gage
glass brush (circular bristle) by pushing the brush through the shank. Using the same brush clean
the faucet body inlet and outlet. Clean the faucet cap and silicone seat cup.
5. After the cleaning, place the parts (sprayhead, brewcone and basket and faucet parts) into a sink
to be sanitized.
CAUTION - DO NOT USE UNDILUTED BLEACH OR CHLORINE.
Mix one of three sanitizing solutions before pouring over the parts
to be sanitized: Chlorine (50 ppm), Iodine (14 ppm), or Quaternary
zz
z
zz
HANDLE
Ammonium compound (100 ppm). This solution should be warm
(75º F.) Let the parts soak for at least one minute.
6. Thoroughly rinse parts with clear, hot water.
7. Air dry, all parts that were sanitized.
8. After cleaning, sanitizing and drying, assemble any partstaken
from the TCT-35 and tea container.

TEA TIPS
1. Store tea bags in a dark, cool and dry place away from strong odors and moisture. Do not
refrigerate.
2. Never hold finished brewed tea for more than eight hours at room temperature. Discard all
unused brewed tea after eight hours.
DO NOT REFRIGERATE UNUSED TEA OVERNIGHT FOR LATER CONSUMPTION.
3. Brew only enough tea that you reasonably expect to sell within a few hours.
4. To protect tea flavor and to avoid bacterial contamination and growth, clean and sanitize tea
brewing, storage and dispensing equipment at least once a day.
5. For any method described, use a thermometer to make sure that brewing water in your
equipment meets the temperature specified.
