This manual provides the user with the necessary information for
installation and operation of the Innova range of Ultra-Low
Temperature freezers with vacuum insulation panels. It also
provides some preliminary user maintenance information.
2.1 Description of Equipment
The New Brunswick Scientific range of Innova freezers is designed to provide
precise, ultra-low temperature environments for scientific and medical use.
CAUTION!
Vacuum insulation panels are used in the construction of these
freezers. These panels are mounted in the cavity against the steel
outer wall of the freezer. Any drilling or puncture to the outer wall
could release the vacuum from the panel, resulting in impaired freezer
performance.
There are two types of Innova freezer: Upright (see Figures 1 & 3 below) and Chest
(see Figure 2 below). This manual covers all versions of these freezer models:
Upright Freezer Model Capacity
U101 3.6 cubic feet (101 liters)
U535 18.9 cubic feet (535 liters)
U725 25.6 cubic feet (725 liters)
Chest Freezer Model Capacity
C585 20.7 cubic feet (585 liters)
C760 26.9 cubic feet (760 liters)
The freezers are totally free of CFCs (Chlorofluorocarbons) and HCFCs
(Hydrochlorofluorocarbons). They use HFCs (Hydrofluorocarbons) as refrigerants.
The interior panels and shelves are made of corrosion-resistant stainless steel,
making them easy to keep clean and to sterilize.
A membrane keypad and digital temperature readout are provided on a small
control panel. On the upright models, this is located on the door. On the chest
models, it is located on a console at the right-hand side of the equipment. (See
Figures 1, 2 & 3)

3
New Brunswick Scientific Co., Inc. User’s Guide
Controls for setting the freezer temperature and alarm warning setpoints are
enabled by an electronic lock. A unique code, which is selected by the user
through the membrane keypad, sets this lock. The code can be changed at any
time, provided the current setting of the lock is known. On delivery, the lock
code is "0000" (unlocked).
Indicator lamps on the control panel provide warnings of power loss, system
failure, exceeding Hi/Low temperature setpoints, low battery voltage and filter
blockage. There is also an LED to indicate when the freezer is under remote
control via the RS-485 optional computer interface.
Figure 1 shows a typical upright freezer, Figure 2 shows a typical chest freezer,
and Figure 3 shows the upright U101 freezer.

2.1.1 Freezer Handles
Freezers are supplied with lockable handles.
The U101, C585 and C760 are fitted with quarter turn key locks.
The U535 and U725 upright freezer handles are fitted with barrel locks (push to
lock, turn key to unlock). The barrel lock may be removed from the upright
freezer handle if the lock facility is not required:
1. Remove the two retaining screws at the rear of the handle.
2. Remove the lock barrel and packing plate.
3. Fit the plastic blanking plug supplied.
4. Refit the packing plate using the existing screws.
#NOTE:
It is important that the handle lock packing plate be fitted at all times.
#NOTE:
For UPRIGHT freezers: DO NOT SLAM THE DOOR WITH THE HANDLE
IN THE CLOSED POSITION.
The door handle has a cam action to pull the door closed and a
reverse can action to break the seal so the door can be opened. When
closing the outer door, ensure that the cam is engaged for correct
operation. The initial vacuum inside the cabinet may cause the door to
appear closed, but when the vacuum releases, the door will open.
Always ensure the handle is properly engaged.
2.1.2 Voltage Stabilizer
Certain freezer models are fitted with an automatic voltage stabilizer. See Section
4.7 for details.

CRUSH WARNING!
DO NOT attempt to lift any freezer by hand. Preferred lifting for
loading and unloading is by hydraulic tail lift.
Maintenance, adjustment and repair work should be carried out only
by QUALIFIED, EXPERIENCED personnel who have been
AUTHORIZED to undertake such work by New Brunswick Scientific
or its authorized agents.
Failure to use authorized service agents may invalidate the warranty.
3.1 Physical Location
All freezers are mounted on castors for ease of movement. Upright freezers have
feet that provide both a leveling feature and a locking feature to stop the freezer
from rolling once it is in place. Chest freezers have locking front castors; these do
not provide leveling adjustment, so the site chosen for the freezer must have a flat,
level floor.
Position the freezer to allow free air entry through the intake grill and free air exit
from the back; provide a clearance of at least 6 inches (150 mm) on all sides. The
grill is located on the front of both chest and upright models (see Figures 1, 2 & 3
above).
For efficient temperature control, the freezer should be placed in a shaded area,
away from sources of excessive heat. For maximum cooling capability, the unit
should be located in an air-conditioned room.
WARNING!
BEFORE connecting the freezer to the electrical supply, make sure
that the power supply matches the requirements of the equipment.
Check the specification plate (located on the side of the freezer) for
the electrical requirements.

7
New Brunswick Scientific Co., Inc. User’s Guide
Model U101 upright freezers are fitted with one fixed shelf. Model U535 and
U725 upright freezers are fitted with two adjustable shelves. These can be
positioned in ½ inch (12.7 mm) steps anywhere throughout the freezer. To
remove the shelf, gently squeeze the shelf clip to release it from the side of the
freezer, then reposition it as required.
3.2 Getting Started
3.2.1 Plug In
Once you have verified that the power supply matches the electrical
requirements of the freezer, connect the unit to the power supply using the
power cord provided.
CAUTION!
If the freezer’s voltage rating does not match your electrical supply, or
if the plug on the power cord does not fit the outlet, do not plug the
freezer in. Contact your laboratory supervisor, safety officer, or
qualified service or electrical engineer.
#NOTE:
Some freezers are supplied with more than one removable power cord.
Utilize the cord that matches your power receptacle. Check the
voltage rating plate on the side of the freezer, to confirm that the
freezer is compatible with your laboratory power supply.
3.2.2 Turn On
The ON/OFF circuit breaker is located within the lockable panel (a) at the
bottom right-hand corner of the upright freezer, or (b) to the left of the
control panel on the chest models. The panel can be removed by turning
the key (provided) one quarter turn to the right. The key can be removed
to prevent access.
Set the ON/OFF circuit breaker to the I(ON) position. The temperature
display illuminates immediately.

8
Innova Ultra-Low Temperature Freezers M1288-0052 User’s Guide
The following models have a built-in voltage stabilizer for the supply
voltage:
•Innova U535, 100-120V and 208-220V, 60 Hz
•Innova U725, 208-220V, 60Hz
•Innova C585, 100-120V and 208-220V, 60Hz
•Innova C760, 208-220V, 60Hz
See section 4.7 for operation.
#NOTE:
The freezer’s compressor will not operate for approximately one
minute after connection of the power supply, because there is an
automatic delay device in the circuit. Temperature and alarm settings,
however, can be adjusted immediately.
3.2.3 Alarm Activation
The equipment is delivered with the battery deactivated. The Power Fail
alarm is activated by the battery rocker switch within the lockable panel. On
upright models, the panel is located at the bottom right-hand corner. On chest
models, the panel is located on front right of the unit, near the display. The
switch is labelled I(ON) and O(OFF). (See Figures 1, 2 & 3.)
To activate the alarm, put the battery switch in the Iposition.
After activating the alarm, test its operation by pressing the ALARM
TEST/MUTE key on the display. The audible alarm should sound. The
ALARM TEST/MUTE key also tests the LED lamps. All of the LEDs should
light up together when the button is pressed.
#NOTE:
When the equipment is first switched on, it will take approximately six
hours to reach a temperature of -86°C. The alarm will sound every 30
minutes until the temperature setpoint is reached. Use the ALARM
TEST/MUTE key to mute the alarm during this initial pull-down period.
If the freezer is turned off during the initial pull-down period, the alarm
will activate 30 minutes after you switch it back on again.
The factory-set temperature is –80º C.

9
New Brunswick Scientific Co., Inc. User’s Guide
3.2.4 Remote Alarm
The freezer is also fitted with a remote alarm socket (see Section 4.4 for
details). This can be tested by turning off (O) the ON/OFF circuit breaker. This
tests the POWER FAIL (see Section 4.1) and ALARM output at the same time. The
battery must be switched on to test the POWER FAIL. The remote alarm facility
provides voltage-free contacts rated at 1 amp, 24 volts maximum.
3.2.5 Vacuum Effect
After closing the door or lid of the freezer, following access to the contents, a
vacuum may be created. Before the door can be opened again, it may be
necessary to wait two or three minutes for the vacuum to be released by the vent
tube. Do not try to force the door or lid. During the release of the vacuum, a
slight hissing may be heard. In order to minimize vacuum formation, the vent
heater assembly has a spring-loaded plunger to clear ice from the inside of the
vent.
#NOTE:
Be careful not to place a rack directly against the vent, as this will
inhibit the plunger’s ability to operate correctly (see Section 5.1.4).

4.1 Operating Controls
Switch the freezer on using the ON/OFF circuit breaker at the front of the
equipment. On upright models (except U101), this is located behind the lockable
panel, low on the right-hand side. On chest and U101 upright models, it is located
behind the lockable panel on the right-hand side, adjacent to the control panel.
(See Figures 1, 2 & 3)
Operating controls are located on a membrane panel mounted in the door of the
upright models U535 and U725. The same panel is located on the right-hand side
of all chest freezers and the small U101 upright model.
Every NBS freezer is equipped with the unique S.M.A.R.T. Plus™ diagnostic
software, to help identify, by means of an error code, the cause of a fault or
setpoint variance.
The available functions, identified by key Item numbers in Figure 4, are described
in the sections below.
4.1.1 Temperature ºC Display
