MODEL 1601 SERIES COFFEE BREWER
COMPONENT MAINTENANCE MANUAL
WITH ILLUSTRATED PARTS LIST
DESCRIPTION AND OPERATION
1. General
TIA Model 1601 Series Coffee Brewer, shown in Figure 1, is an aviation quality,
general purpose top fill brewer capable of making 48 oz. (10 cups) of coffee every
brew cycle. The brew tray allows for the use of a standard coffee filter and loose
coffee, or a commercial pillow pack. An integral heater assembly both brews the
coffee and provides a heated surface to keep the coffee warm.
Temperature and overheat controls are provided independently by means of single
setpoint bi-metal thermostats for each to minimize maintenance and increase
reliability.
The coffee brewer is not designed to operate in a completely enclosed compartment.
Compartment doors should be open during operation to prevent a build-up of heat
and humidity.
2. Description
A. A single POWER switch operates the unit and, when in the ON position, allows
the water to be heated to a point (controlled by the control thermostat) at which
the heated water “percolates” up the brew pipe, over the coffee in the brew tray
and into the carafe.
B. A manually resettable overheat thermostat will deactivate the heater elements if
the temperature exceeds its set point. Activation of the overheat thermostat
indicates a fault. The overheat thermostat must be manually reset before
operation of the coffee brewer can resume.
3. Operation
NOTE: The primary cause of slow brew cycles is the buildup of mineral deposits in
the heater block.
A. Turn the brew basket retainer latch downward and remove brew basket. Insert
the new filter and load fresh coffee into the brew basket. Place the brew basket
back into the coffee brewer and latch into position.

MODEL 1601 SERIES COFFEE BREWER
COMPONENT MAINTENANCE MANUAL
WITH ILLUSTRATED PARTS LIST
NOTE: Unit should be off and cool before filling it with water. Adding water to a hot
coffee brewer will create a puff of steam.
B. Fill the carafe with water and pour it into the water fill port located on the top of
the coffee brewer. Watch the water level indicator to avoid overfilling the water
tank.
OPERATING HINT: To prevent carafe overflow, make certain that the amount
of water poured into the coffee brewer does not exceed the capacity of the 54
oz. carafe. DO NOT add water during the brew cycle. Remember that the
carafe must be able to hold the amount of water poured into the coffee brewer
tank. Verify that carafe is empty prior to beginning brew cycle
NOTE: Only pour fresh water into the water tank. Do not pour coffee or other
premixed liquids into the water tank. Doing so will result in damage to the
coffee brewer.
C. Switch coffee brewer ON. The indicator light will illuminate on units equipped
with indicator lights (P/N 500-0521-01, -02 and 500-0619-01, 02 ONLY). After
approximately 30 seconds water will start percolating through the brew basket
and into the carafe.
D. When brew cycle is completed and coffee has ceased flowing into the carafe,
remove brew basket from coffee brewer and discard coffee grounds.
NOTE: Coffee may continue to drip from the brew basket after the completion of the
brew cycle. The dripping is from residual liquid in the brew basket and does
not indicate a fault with the Coffee Brewer.
E. Remove carafe from coffee brewer and serve coffee. Return carafe to coffee
brewer after serving coffee and latch into position. When finished serving
Coffee, turn the coffee brewer OFF.
CAUTION: DO NOT HEAT EMPTY CARAFE.

5. Storage Instructions
A. Preparation for Storage
(1) Ensure that all liquids have been drained from the coffee brewer and
components to prevent possible damage if the unit is exposed to freezing
temperatures.
(2) Store the coffee brewer upright in a clean, dry location where the unit will not
be subject to dents or other damage.
(3) Whenever possible, the unit should be stored in the shipping or packing
container originally provided by the manufacturer.
NOTE: Inserts may be stacked in accordance with standard warehouse
practices.
(4) If inserts are to be stacked, a separator of ¼ inch plywood, or similar
protective device, is to be placed between the units to insure against damage
to the finish or component parts.
B. Short Duration Storage
NOTE: No special protection is required if the units are to be stored less than
three months.
(1) If units are stored in excess of thirty days, complete test procedures should
be performed prior to placing the unit in service.
C. Extended Duration Storage
Wrap units in water repellant material (Federal Spec. VV-P-271 or equivalent) and
enclose silica gel packages to absorb moisture and retard corrosion.

TESTING AND FAULT ISOLATION
1. General
A. This section consists of the following subsections: Testing and
Troubleshooting.
(1) The Testing subsection is a general functional test of the coffee brewer
to determine in which area a fault may have occurred.
(2) The Troubleshooting guide describes the most common possible faults
and their remedies. It is meant to serve as a general guide and
assumes that all internal wiring and power connections are correct.
B. The 1601 series coffee brewers have single setpoint thermostats. Brew
temperature calibration is not adjustable. The thermostat does not control
the brew temperature, it controls the temperature of the heater block.
2. Testing

3. Troubleshooting Guide
These guides address the most common potential problems associated with these models.
It is not intended to solve more in-depth faults.
A. All Model 1601 Series
Fault Probable Cause Effectivity
(1) After the brew cycle
is completed and
carafe has been
sitting on the warmer
tray, unit switches off
and will not switch
back on.
(2) When unit operates,
steam rises.
(a) The overheat thermostat has
disconnected power from the
heaters. Allow unit to cool and
reset thermostat.
(b) Overheat thermostat may be
defective.
(c) The thermostat and/or its relay
have failed.
When the coffee brewer operates, the
normal functioning of the machine
generates some steam. If the steam
becomes “excessive”, remove the
brew basket from the coffee brewer
and observe the water flow for
consistency. A primary cause of
excessive steam is the build-up of
mineral deposits in the heater casting.
For cleaning details, refer to the
cleaning section of this manual.
