BREWING INSTRUCTIONS
SPECIAL INSTRUCTIONS FOR BREWING
WITH FILTER PACKS
SEPARATINGSPRAYHEAD
If you will be using tea that is packaged in a filter pack, it is recommended that the
waterspreaderportionofthetwo-pieceSprayheadberemoved.Thiswillallowfora
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(withthe sprayheadstillon thebrewer)and pullit firmly
downward.Thetwopieceswillseparate, leavingthethreaded half stillonthe
machine.
Caution: Do not pull out brew cone until it stops dripping
to avoid scalding from hot liquid.

PROBLEM:Low temperature orcold waterin theheating tank.
POSSIBLECAUSE SOLUTION

will go.
PROBLEM:No responsewhen BrewSwitch isdepressed. Nohot or coldwater dispensed.

Disconnectthewater linefromthe inletvalve andcheckthe waterpressure. Recon-
nectthe waterline.Replace thefilter cartridgeandremove anyobstruction. Note:
Theminimumpressureon theinlet valveshould be20 PSI.
While pressing the Brew Switch, check for continuity between the two side termi-
nals, 4B and 5B. If you do not read 110 - 120V from 5B to L2, the switch is defec-
tive.Replace theswitch.
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
thereis no voltage, replace thetimer.
PROBLEM: No hot water flowing from Sprayhead. Only cold water cycles.

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
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.

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.
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.
