5800 Refrigerator Compressor
Capacitor/Relay Kit
Instruction Sheet
Overview
The refrigerator compressor relay and capacitor are
components of the Teledyne Isco 4700 and 5800
refriger-ated samplers. These instructions cover their
removal and replacement in both models.
Section one of this instruction sheet describes how
to access the refrigeration components. You must then
determine which voltage rating and type of startup relay
and capacitor you are replacing. Section two provides
instructions appropriate for your refrigerator.Section
three re-installs the refrigeration module, and section
four tests operation following the installation.
Before attempting to remove and replace a module,
observe the following precautions:
WARNING
Removing a module exposes you to electrical and
mechanical hazards. Always disconnect the AC
power cord before attempting to remove any
module. Only trained service personnel may
remove or replace these modules.
CAUTION
Removing the sealed modules will expose the internal
components. Wet or corrosive atmospheres may attack
the exposed refrigerator components. Always service
modules in a dry, corrosion-free environment.
CAUTION
Modules contain circuit boards and sensitive electronics
that can be damaged by a discharge of static electricity.
Avoid touching the internal components. Only handle
the module by the edges or exterior surfaces.
CAUTION
Electrical connectors and wires can be damaged if
improperly handled. Electrical connectors must only be
handled by the connector body. Never grasp the wires
or use tools to disconnect a connector. Never allow a
module to hang by its wiring.
CAUTION
Earth ground bonding conductor. Do not
remove or disconnect. If this conductor must
be disconnected to remove a module, it must
be reconnected when installing the
replacement module.

4. Remove the refrigeration module mounting
screws (Figure 3).
Note that older refrigeration modules have an
adhesive strip just above the rear coils. The bot-
tom center screw may be slightly hidden by this
strip.
5. Carefully pull the module out and rotate clock-
wise to expose the wiring connectors.
The bushing holding the AC line cord in place
should slide along the cord (see below). During
reinstallation, the slack created in this step must
be removed.
CAUTION
Keep the module as close to the refrigerator body as
possible to avoid pulling the wiring taut and damaging
the connectors.

box. If needed, use a screwdriver to release the
locking tab.
2. Unplug the white connector with the orange and
black wires from the bottom 2 pins on the com-
pressor (Figure 6). On newer models this con-
nector will be black and the wires will be orange
and white. The orange wire always goes to the
left.
3. Disconnect the blue wire from the capacitor/
relay assembly from the blue wire from the
power supply (Figure 6). On newer power sup-
plies the power supply wire will be gray.
4. Disconnect the black wire from the capacitor/
relay assembly from the ribbed black fan wire.On
newer refrigerators the second black wire from
the cap and relay assembly goes to the wrap
around heater on the compressor.Ifthe com-
pressor has no heater then second black wire is
not used. Tape the wireoff and tuck away.
5. Remove the capacitor/relay assembly.
A 5/16-inch socket, short extension, and a 1/4-inch
ratchet driver are recommended to loosen the
lock nuts. Once loose, lift the assembly to
remove it (Figure 4).

The refrigeration module and rear compartment of
the cabinet have adhesive strips and Permagum1
(caulking cord sealant) protecting the components
(Figures 9 and 10). Ensure that all adhesive strips and
Permagum are still in place before reassembly.
The adhesive strips and Permagum are required to
prevent air flow between the condenser coil and the
evaporator plate. Without this protection, water con-
densation on the coil will cause ice build-up, resulting in
poor refrigerator performance.
Note
Two thick, black cables connect the power supply with
the AC and compressor (see Figure 9). Ensure that
these cables are side by side and not crossed
during reassembly.

8. After 45 minutes, perform the refrigerator
temperature diagnostic test, as described in
the following section.
4. Refrigerator Temperature Diagnostic
The REFRIG TEMPERATURE diagnostic displays the
temperature of the refrigerated compartment.
To start the diagnostics from the standby screen:
1. Select the CONFIGURE option and press ENTER.
2. Press the left arrow button until the RUN
DIAGNOSTICS option is displayed. Press ENTER.
3. Press the right arrow key 7 times to display
REFRIG TEMPERATURE. Press ENTER to start the test.
When this test is started, the sampler should display
the temperature until you press the STOP or ENTER
button. There is no pass or fail. This test simply
provides continuous temperature monitoring.
As the refrigerator cycles off and on, the reported
temperature will rise above and below the set
temperature. However, the average reported
temperature should be the same as the configured
temperature. The evaporator temperature may at times
read as low as –20° C; this is considered normal.
If the screen displays an asterisk (*) or inaccurate
temperature reading, the temperature sensor cable may
be malfunctioning.
