Figure 3 - Place shelves at desired height on four
shelf supports.

Electrical Connection
The frequency and nominal voltage requirements for the
unit are specified on the data plate, which is located on
the interiors upper left side. Only plug the unit into a
power source that meets these requirements. Low line
voltage is often the cause of service complaints.
With the unit running, check that the line voltage is
within ±10% of that specified on the data plate.
The power cord of this instrument is equipped with a
three prong (grounding) plug (NEMA 5-15P). This plug
mates with a standard three prong (grounding) wall recep-
tacle (NEMA 5-15R) to minimize the potential of an elec-
trical shock hazard. Chromatography models are
equipped with a (NEMA 5-20P). This plug must mate with
a (NEMA 5-20R).
The customer should have the wall receptacle and circuit
checked by a qualified electrician to verify the receptacle
is properly grounded and meets power requirements
specified on the data plate.
Where a two prong wall receptacle is encountered, it is
the personal responsibility and obligation of the user to
have it replaced with a properly grounded three prong
receptacle.

UNPACKING AND INSTALLATION
Caution
Be sure that the power supply is the
same voltage that is specified on the
refrigerator's data plate.
Warning
Insufficient line voltage is often the
cause of compressor start-up failure.
It is strongly recommended that a
dedicated circuit, conforming to the
National Electrical Code, Article 440,
be used for powering the refrigera-
tor..
Warning
DO NOT under any circumstances cut
or remove the third (ground) prong
from the power cord. DO NOT use a
two-prong adapter plug.
Warning
For personal safety this unit must be
properly grounded.
Warning
Do not use an extension cord. Use
of an ungrounded cord or an over-
loaded circuit VOIDS the compres-
sor warranty.

Before operation, become familiar with the refrigerator
controls located on the refrigerator header panel. A layout
of the controls is given below.
Controls Layout
Begin operation by inserting the key into the key switch
located on the header panel. The key switch is packed
inside the envelope, which is shipped in the refrigerator
chamber. Turning the key switch to the ON ( | ) position
will energize the evaporator fans and the digital controller.
Temperature Controller
The digital temperature controller is located on the left
side of the header panel (See Figure 4). When the unit is
initially turned on, the display will indicate current cham-
ber temperature. The temperature units will be indicated
by the °C or °F LED located just to the right of the tem-
perature display. The refrigerator is factory set at 4°C.
When the unit is first energized the evaporator fans will
operate however it will not immediately cool. A 3-minute
compressor delay is programmed into the controller to
provide sufficient time for the evaporator to defrost and to
allow the system pressure time to equalize. When the
delay time is over, the Cool LED will illuminate, the com-
pressor will run and the chamber will cool.
Operation
Warning
If the unit is tilted in excess of 30
degrees, do not apply electrical power
for a minimum of 12 hours.
Warning
This product is NOT approved for stor-
age of flammable or explosive materi-
als. Also, it is NOT approved for use in
hazardous locations containing explo-
sive atmospheres.

Note
The compressor requires a 3-minute
delay time between activations. The
unit will not cool during this delay.
The delay is also activated when the
controller is first energized.

10
Setting the Temperature
To change the set temperature, press and release the
Menu keypad once. The display will flash SP and the
Mode LED will be illuminated. The last set temperature
will then be shown in the display. To change the tempera-
ture, press the UP or DOWN arrow key. The adjustable
temperature range is 1 to 12°C (34 to 54°F). When the
desired set temperature is displayed, press the Menu key-
pad to enter the set temperature and activate the Units
Select menu.
Units Select
The second menu selects the units. The refrigerator con-
trol displays temperature in °C or °F. The factory setting
is °C. Starting from the temperature display mode (Mode
LED off), press the Menu key twice. The current temper-
ature units are displayed. To switch between units, press
the UP or DOWN arrow key then press the Menu key to
select. The unit LED will be displayed on the right of the
temperature display.
Calibration Offset
In the event the refrigerator needs to be calibrated, a sim-
ple routine is available to adjust the display and control
point to a referenced standard. To set a temperature off-
set, press and hold the Menu keypad for 5 seconds. The
display will flash oS followed by the last temperature off-
set value. The factory setting is 0. To change the offset
value, press the UP or DOWN arrow key, then press the
Menu key. The value shown in the display will be added
to the previous temperature reading. The display will
then flash Ho.
For Example:
The display indicates 4°C but a reference thermometer in
the refrigerator chamber indicates 6°C. The operator
presses and holds the Menu keypad for 5 seconds, then
changes the display value from 0 to +2 by using the UP
arrow key. Press the Menu key again. Now the display
indicates a chamber temperature of 6°C and the con-
troller begins to cool (as long as 3-min. delay period has
expired) to the desired temperature of 4°C as shown on
the reference thermometer.
OPERATION

Allow an additional 30 to 40 minutes for the refrigerator to
again stabilize. If the display is still inaccurate, repeat the
calibration offset procedure.
Hold Off Time
Following the offset menu is the hold-off (Ho) menu. The
display will momentarily flash "Ho", followed by a number.
The number shown is the delay time in minutes between
compressor activations. Use the UP/DOWN keypads to
change the value.
Increasing the hold-off time will allow additional time for
the evaporator to defrost during the off-cycle. This can
reduce the chance of evaporator freeze-up during times
of high humidity. Pressing the Menu keypad while in the
Ho mode, enters the hold-off time displayed, and returns
controller operation to the temperature display mode.
Error Codes
Error codes indicate when the controller is sensing a
problem. A description of each is given below. See the
Troubleshooting Table for additional information on error
codes.
E1 Open sensor.
E2 Under temperature. Temperature at sensor is
less than –36°C.
E3 Over temperature. Temperature at sensor is
greater than 37°C.
Fluorescent Lamps
The interior lamp is controlled by a rocker switch on the
header panel. This light may be operated any time the
cabinet power is turned on at the keyed power switch. If
the interior lamp fails, replace with the same size and
wattage lamp. DO NOT USE REDUCED WATTAGE
LAMPS. The reduced wattage lamps generally fail to
light below 60°F (15°C).
11
OPERATION
Caution
INCREASING the offset value
DECREASES the temperature at
which the system controls. If the off-
set is inadvertently set too high, the
chamber’s control temperature can fall
below zero and cause evaporator
freeze-up. This is caused by the
evaporator temperature not rising
above 0°C and not defrosting during
the compressor “off cycle”.
Note
While in any of the controller mode
setups (temp set, calibration offset
or units), the controller will wait 15
seconds for a new value to be
entered. If there is no keypad oper-
ation within the 15-second time win-
dow, control will automatically revert
to the temperature display mode and
the Mode LED will turn off.

Convenience Outlet
(Chromatography Refrigerators Only)
Chromatography Refrigerators come equipped with a con-
venience outlet located in the center of the back wall.
Model 172G’s (three doors) have two convenience out-
lets. The total power that can be supplied by the outlet
(or outlets in 3-door models) is 5A @ 120VAC (4A @
120VAC for the 3-door models). The outlet(s) is protected
by a circuit breaker located just below and to the right of
the outlet(s). Pressing the breaker button resets the
breaker after a fault.
Manual/Automatic Condenser
Fan
Arocker switch located on the left side of the top of the
inside of the chamber is used to operate the condenser
fan automatically or manually. With the switch in the
automatic position, the condenser fan operates with the
compressor. In the manual position, the condenser fan
operates continuously.
During times of high ambient relative humidity conditions,
more water is condensed on the evaporator and directed
to the condensate pan. The condenser fan will run con-
tinuously in the manual setting to better dispose of this
water. At times of low relative humidity, the switch can be
set to automatic.
12
Warning
The convenience outlet is LIVE at any
time the unit is connected to an elec-
trical power source, regardless of the
position of the key switch.

Troubleshooting

14
Cabinet Cleaning
The cabinet interior should be cleaned frequently. Any
spilled liquid should be wiped off immediately. Stains
resulting from some spills can be permanent if not quickly
removed. The most convenient time to clean the interior
is after defrosting. The cabinet exterior should be
cleaned occasionally. A mild detergent and lukewarm
water or a solution of bicarbonate of soda (1 tablespoon
per gallon of water) is recommended for cleaning the inte-
rior and exterior of the cabinet. All surfaces should be
rinsed and thoroughly dried.
Cleaning the Condenser
For efficient operation, it is recommended that the con-
denser coil and fan be cleaned every 4 to 6 months. The
condenser coil is located behind the base grille, at the
bottom of the unit. See Leveling the Unit for instructions
on removing the base grille.
Vacuum clean the front surface of the coil thoroughly, or
direct forced air through the condenser from the rear. If
necessary, use a stiff bristled brush to loosen any dirt.
Failure to keep the condenser clean will void the warran-
ty.
Condensate Evaporator Pan
The condensate evaporator pan is located behind the
base grill between the condenser fan and compressor.
This pan should be cleaned at least once a year to pre-
vent foul odors and operate efficiently. Vacuum clean if
dry, or sponge clean with soapy water.
Maintenance
Caution
When servicing the unit, disconnect
plug from the electrical power source
Caution
Do not use any type of abrasive such
as steel wool or fluids, such as gaso-
line, Naptha or paint thinner, that
could be harmful to plastic materials,
door gasket and/or painted surfaces.
Caution
Accessing and cleaning the condens-
er coil or evaporator pan should be
done by qualified personnel.
