5.6. Display battery backup (optionally for ZLN, ZLN-T, ZLW-T, standard for
ZLN-UT VIP)
Units in the SMART PRO version can be optionally equipped with a battery backup of the display. This is a standard
equipment for the ZLN-UT VIP ultra-low freezers.
The power loss and switching to the battery backup display mode is signaled by a pulsating red frame around the display and a sound signal (if it is turned on). In the battery backup display mode, all parameters are displayed, ie temperature. Other alarms, e.g. exceeding the temperature range, are also signaled.
In order to extend the battery life, the display is dimmed all the time. Batteries are automatically charged in AC mode.
Batteries should be replaced every 12 months. During the warranty period, the replacement should be
performed by an authorized service. Otherwise, you will lose your warranty.

6.7.2. Segments edition
For each program, you can set maximum 100-segment time-temperature profiles that allow you to gradually increase
or decrease the incubation temperature of the samples. This can e.g. protect the sample from so-called thermal shock.
Example of program operation with programmed segments (parameters priority):
Program 1 (for ZLN-T/ZLW-T)
segment1: temp. -5C, time 2 hours (after reaching the temperature -5C, it is maintained for 2 hours)
segment2: temp. -10C, time 3 hours (after reaching the temperature -10C, it is maintained for 3 hours)
segment3: temp. -15C, time 3 hours (after reaching the temperature -15C, it is maintained for 3 hours)
segment4: temp. -20C, time 2 hours (after reaching the temperature -20C, it is maintained for 2 hours)
segment5: temp. -30C, time 2 hours (after reaching the temperature -30C, it is maintained for 2 hours)
segment6: temp. -40C, time  (after reaching the temperature -40C, it is maintained in continuous way)
Press the buton
and the first program segment will appear (Figure 20).
In this window you can set:
•
temperature – target temperature which the device is to achieve in this segment
•
time – the time of maintaining the set temperature ([d hh:mm]) in days, hours and minutes. It is possible to
select continuous work ∞ in the last segment,
•
ramp time – the time of reaching the set temperature ([d hh:mm]) in days, hours, minutes.
The active value is highlighted in blue. The item highlighted in red means that the value is out of range and you should
enter another one, e.g. the temperature is above / below the operating range of the device or the protection
temperature.
In ZLW-T 200 and ZLW-T 300 freezers the fan is set to 100% by default and cannot be changed.
34

Ramp time - setting a short time will not accelerate reaching the ramp, but the ramp will be reached in the
shortest possible time depending on the set temperature, ambient conditions and the possibilities of the
cooling system in the device.
The ramp parameters are factory set in accordance with the manufacturer's instructions. If it is necessary to set
individual parameters when reaching the segment temperature, activate the ramp edition field

36
Instruction manual ZLN, ZLN-T, ZLW-T, ZL-UT VIP SMART PRO
6.7.4. Priority
Can be set in terms of:
Parameters:
In the program without ramp – the device starts the countdown of the segment time when the set temperature is
reached.
In the program with ramp – first, the device counts down the time of the ramp and then proceeds to the segment
countdown when the set temperature is reached. Regardless of whether the time of ramp elapsed.
It may happen that the device failed to reach the set temperature within the set time because the reaching time was too short. In such situation the reaching time will be prolonged and the segment’s time
countdown will start when the set temperature will be reached.
Time:
In the program without ramp – the device starts counting down the segment time when the program is started. Regardless of whether the temperature has been reached.
In the program with ramp – first, the device counts down the ramp time and after its expiry it proceeds to the countdown
of the segment time. Regardless of whether the temperature has been reached.
It may happen that the time of reaching was too short and the device failed to reach the set temperature
within the set time. Then the countdown of the segment time will start before reaching the set temperature. Thus, the actual time of device operating in the set temperature will be shortened.
6.7.5. Loop
The option is available if the number of segments is equal to 2 or more (maximum 100). When the program finishes the
last segment, the device starts the program again from the first segment. You can define if the program should be
carried out once (loop: 1) or multiple times (loop: 2 to 255). In order to set the program to be carried out continuously,
tick the „∞” option. If the time of the last segment is set to infinity, it will be treated as infinite only in the last cycle. In
other cycles it will be treated as 0.
Example:
Loop:3
segment1: temp. -10C, time 2 h
segment2: temp. -30C, time 2 h,
segment3: temp. -40C, time „∞”
The device will run segment1 and segment2 three times and then will go to segment3 which will last indefinitely.
Due to the fact that laboratory freezers do not have a heating system, when switching from a lower to a higher
temperature, the compressor turns off, and the temperature rises naturally, which greatly extends the cycle. The cycle
duration can be determined empirically.
6.7.6. Defrosting of ZLN, ZLN-T, ZLN-UT VIP devices
During operation, a layer of ice may form inside the freezer’s compartment. The speed of ice or frost formation depends
on several factors: ambient conditions (temperature, humidity), how often the door is opened, and the type of samples.
When an ice or frost layer covers the entire chamber, defrosting is necessary. Defrosting is performed manually in the
following order:
37
Instruction manual ZLN, ZLN-T, ZLW-T, ZL-UT VIP SMART PRO
1.
turn off the device (unplug the power cable from the socket),
2.
open the door and allow the device to defrost (do not accelerate the defrosting process),
3.
wipe dry the water accumulating on the bottom and the walls of the chamber,
4.
turn on the device (insert the power plug into the socket).

• the start time of the next program on the list cannot be earlier than the end time of the previous program,
• the program end time cannot be later than the start time of the next program,
• the end time of the next program does not have to coincide with the start time of the next one, there may be a break
between them,
• if the program is not fully completed (due to setting a too short time of a schedule), it will be interrupted.
When choosing time intervals, consider whether they are long enough for the selected program to be
implemented. The duration of the program can be affected by: ambient conditions, samples and the
program carried out immediately before it.

condensate drain system. Defrosting has additional parameters to set:
•
preheat time of the tray [s] - time before defrosting during which the condensate drain system should be
preheated,
•
evaporator temperature [°C] – temperature (on the evaporator) for the end of defrosting. Defrosting ends
when the evaporator reaches the set temperature or after the time set in the time parameter has elapsed,
depending on what occurs first.
67
Instruction manual ZLN, ZLN-T, ZLW-T, ZL-UT VIP SMART PRO
User can set parameters such as: time, preheat time of the tray, evaporator temperature.
CAUTION: too low values may cause that the accumulated ice will not melt during the defrost cycle, which
may result in increased icing. However, higher values can cause an unnecessary increase of the
temperature in the chamber.
Pressing the button
– restores the default defrost settings (period [h]: 2, time [s]: 120, delay [m]: 0,

Go to the main menu
and press the icon
. In this panel (Figure 69). You can set parameters related to the
temperature measurement in the equipment using an additional temperature sensor.
Additional sensor
The following parameters can be set relative to the additional temperature sensor:
•
mode – sensor operation mode:
disable – the sensor is switched on,
measure – displaying in the main window and recording temperature from the additional temperature
sensor,
compensation - displaying in the main window and recording temperature from the additional
temperature sensor + compensation,
•
rate [C°/min] – determines how fast the equipment is to respond to differences in temperature indications
between the additional temperature sensor and the main sensor (higher value = faster response of the
equipment, can affect the stability of temperature maintenance),
•
limit – parameter which defines the acceptable difference in temperature compensation during operation; the
limit range is from 2°C to 8°C.
68
Instruction manual ZLN, ZLN-T, ZLW-T, ZL-UT VIP SMART PRO
Compensation
The compensation value is a correction for the regulation of the main sensor in order to obtain the set temperature at
the place of measurement of the additional sensor. To control the equipment according to the additional temperature
sensor’s indications, select the "compensation" operating mode. An additional temperature sensor can be used to
control the temperature in the chamber according to e.g. sample temperature.

Confirms changes
Cancels the entered changes
6.23.
Corrections
Press the icon of the main menu
and then press
. In this window (Figure 70) you can correct temperature
value indicated on the display by adding the correction value. The set correction value applies to the whole temperature
range of the device. For example, if the average temperature displayed by the device indicates -20,0°C and the
average temperature measured by independent, external sensor indicates -20,5°C, the correction should be set on 0,5°C. The average temperature should be calculated from chosen period of time e.g. 30 min. The correction available
range is between -5°C to +5°C.
The device has been calibrated by the manufacturer in accordance with applicable norms. The temperature
shown on the display corresponds with a great accuracy to the temperature near chamber’s sensor. For the
correct operation of the device it is not necessary to use user’s calibration. The user is performing
temperature correction on his own responsibility and must be aware of consequences of changing
manufacturer’s settings. If the equipment was calibrated, calibration certificate loses its validity.

8. CO2 BACK-UP SYSTEM (OPTIONALLY FOR ZLN-UT VIP)
The CO2 back-up emergency power supply system is used in ZLN-UT ultra-low freezers and provides protection against temperature rise in the chamber and maintains a safe temperature of the samples in the event of a power outage.
An increase of temperature above 10°C from the set temperature and loss of power supply causes the dosing of liquid
CO2 to the chamber. The amount of dispensed liquid CO2 is regulated by a microprocessor controller. The minimum
operation temperature for the CO2 back-up system is -70°C and results from the physical properties of carbon dioxide.
If the chamber door is open during CO2 dosing, the gas will be automatically cut off.
Time of temperature maintenance by CO2 back-up system depends on:
•
capacity of CO2 cylinder,
•
ambient temperature,
•
type and temperature of samples at the moment of power failure,
•
degree of freezer filling.
Theoretically, a full 50l high-pressure cylinder is enough for 8 hours of CO2 back-up operation in the ZLN-UT 300 VIP
freezer (set temp. -80°C).
71
Instruction manual ZLN, ZLN-T, ZLW-T, ZL-UT VIP SMART PRO
• During the operation of the CO2 back-up emergency power supply system, a significant amount
of CO2 enters the room, which in high concentration can be life-threatening. The device does not
emit CO2 when working with the power supply switched on.
• The CO2 back-up system can’t be operated near concentrated acids or corrosive vapors.
• The key to turn off the CO2 back-up emergency power supply system must always be in an
easily accessible place.
• The workplace must be properly ventilated!
8.1. Indications for using pressure cylinders
The liquid CO2 pressure cylinder is NOT supplied with the freezer with CO2 backup system. The purchase,
transport and connection is the responsibility of the user.
•
•
•
•
Together with a pressure cylinder with compressed or liquefied gas, the user should be given a safety data
sheet for the gas and instructions for its use.
The ventilation performance in the room must ensure levels of gas concentrations in the rooms below the limit
values.
Opening the pressure cylinder valves is only permitted if the cylinders have been connected to the receiving
installation first.
During gas intake from the gas cylinder, check the pressure level regularly.
8.1.1. Characteristics of carbon dioxide
Carbon dioxide (CO2) is a colorless, odorless, non-flammable and slightly acidic liquid gas. CO2 is heavier than air and
soluble in water.
Warning signs on the bottle containing CO2
Non-flammable and non-toxic
gases
Pressurised gas
Product ID: Carbon dioxide (100%)
Chemical formula: CO2
Application of the substance: General industrial applications
Supplying gases other than CO2 to the freezer is UNACCEPTABLE.

Hazards when working with CO2
The bottle contains compressed gas that may cause cryogenic burns or injury (extremely cold liquid and high
pressure gas).
Carbon dioxide in elevated concentration causes shortness of breath, circulation problems and ultimately death.
Avoid breathing gas.
8.1.3. Personal protection
1)
2)
Hand protection
Wear loose fitting thermal-insulated gloves or gloves for handling cryogenic liquids. Norm EN 511 - protective
gloves against the cold.
Eye or face protection
Wearing safety glasses is recommended when working with the bottle. Protect eyes, face and skin from splashes
of liquid. Use safety goggles and face shield when reloading the product or disconnecting the transmission
connections. Norm EN 166 – Personal eye protection.
3)
Skin and body protection
Never touch with exposed body parts uninsulated elements of the CO2 backup system. Extremely cold metal can
cause the body to stick quickly and to damage it (detach) when attempting to retract.
4)
Respiratory protection
In an atmosphere where there is a lack of oxygen (excess of carbon dioxide), use a self-contained breathing
apparatus or a face mask with a positive pressure air supply. Respirators with air filters will not provide protection.
8.1.4. Control devices
To prevent the accumulation of gas above the permissible concentrations in the room, natural or mechanical ventilation
should be provided. In addition, a natural or mechanical installation must be provided to prevent the oxygen
concentration from falling below 19.5%.
According to the recommendations, the highest acceptable concentration of CO2, that affects an employee during the
8-hour daily and average weekly working time specified in the Labor Code is: 9000mg / m3. Maximum permissible
instantaneous concentration: 27,000mg / m3
It is recommended to use control and measurement equipment for measuring CO2 concentration in rooms
with a CO2 backup system.
8.1.5. First aid
Contact with eyes: In case of contact with eyes, rinse them immediately with plenty of water and seek medical advice.
Keep eye wide open while rinsing.
Skin contact: In the event of frostbite, seek medical assistance immediately. Whenever possible, immerse the affected
area in a warm bath not exceeding 40°C (105°F). Do not rub frostbitten parts of the body as it may cause tissue
damage. Apply a sterile dressing to the wound.
Inhalation: Move the victim to fresh air. CO2 gas is heavier than air and accumulates e.g. at the floor. If breathing has
stopped or is difficult, give aided respiration. Oxygen administration may be indicated. In the event of cardiac arrest, a
trained person should immediately begin cardiopulmonary resuscitation.
73
Instruction manual ZLN, ZLN-T, ZLW-T, ZL-UT VIP SMART PRO
in life-threatening emergencies:
1) protect yourself with a breathing apparatus,
2) remove the victim from the contaminated area,
3) call a doctor,
4) start CPR.
In the event of a gas leak:

Steel hose for connecting CO2 cylinder with 1/4'' SAE internal thread
CO2 back-up system
The manufacturer supplies the device with a specialist steel hose with a length of 1500 mm. This hose is used to connect CO2 cylinder. On one side the hose is screwed to the CO2 back-up system - DO NOT unscrew it. On the other
side, it should be screwed to a CO2 cylinder (see below "Connecting the equipment to a CO2 cylinder"). The kit comes
with a reduction on cylinder W21,8 x 1/4 '' SAE. The minimum bend radius of the hose is 110 [mm].
75
Instruction manual ZLN, ZLN-T, ZLW-T, ZL-UT VIP SMART PRO
The bending radius of the steel hose should not be smaller than specified in the documentation, otherwise
the hose or its teflon inner coating may be damaged. Prevent:
•
sharp hose bends near the ends,
•
twisting, cutting, rubbing, stretching and squeezing the hose,
•
exceeding the maximum solenoid working pressure of 70 bar,
•
if you notice any signs of damage of the components, replace it.
To connect the freezer to a CO2 cylinder you have to:
1) place the CO2 cylinder vertically and attach it to the wall with a special clamp, rope or chain,
2) screw the supplied reduction W21,8 x 1/4 '' SAE on the cylinder connector,
3) screw the hose to the reduction,
4) slowly unscrew the valve while checking low leakage connection,
5)
after connecting the cylinder correctly, press the main menu icon
the button
and then press
(Figure 73); press
(Figure 74) and carry out the solenoid valve opening test.
When working on CO2 back-up system is recommended to lock the freezer’s door with a key.

Instruction manual ZLN, ZLN-T, ZLW-T, ZL-UT VIP SMART PRO
CO2 back-up system should be connected to a siphon cylinder.
The manufacturer does not provide the equipment with a CO2 cylinder.
Water condensation on the solenoid valve and steel hose is a natural phenomenon (only during operation
of the CO2 back-up system).
Connection to a CO2 cylinder should be made by a person who has undergone appropriate training.
8.5. Disconnecting the freezer from the CO2 cylinder
To disconnect the freezer from the CO2 cylinder:
1) close the cylinder’s valve,
2) press the main menu icon
3)
, and then press
(Figure 73); using the button
perform the solenoid valve opening test three times to empty the gas in the connection,
unscrew the connection and reduction of W21,8 x 1/4 '' SAE from the CO2 cylinder.
(Figure 73)
8.6. Starting the device
To start the device, turn the key of the rotary switch (Figure 72) of the CO2 back-up system to the "ON" position, and
then turn the main switch to the "I" position.
It is not recommended to open the freezer door during operation of the CO2 back-up system because it
causes a sudden increase of the temperature in the chamber of the equipment, and thus an increase in
the amount of CO2 dosed.
During the system operation, frost will accumulate in the device - this is normal. CO2 dosing is done through the
nozzles inside the freezer.
The manufacturer does not recommend placing the samples directly under the CO2 nozzle. Covering the
perforations on the device shelves reduces the efficiency of the system.

Instruction manual ZLN, ZLN-T, ZLW-T, ZL-UT VIP SMART PRO
9. CONNECTING THE DEVICE TO A COMPUTER
Each device in the SMART PRO version can be connected to an Ethernet network or directly to a computer with a LAN
cable (standard equipment). Using the Lab Desk program (standard equipment), you can program and monitor the
operation of multiple devices with the SMART PRO controller. The features of the software have been described in a
separate instruction manual.
10. CLEANING AND MAINTENANCE OF THE DEVICE
Disconnect the device from the power supply before carrying out any activities related to the
cleaning! In the case of the battery back-up of the controller, also turn it off.
On the internal walls of the device (in particular the new one) made of stainless steel, discoloration (spots) may appear
- which are not caused by factory defects, but only by the steel production process. They can be cleaned using
extraction gasoline.
INOX products are manufactured with stainless steel. When used in standard laboratory conditions they do not rust.
However it is possible that stains (which may look like rust) form on the steel surface (e.g. due to the kind of samples
that are incubated in the chamber). In such case we recommend using cleaning solution (to clean the stains) which is
dedicated to this particular application, e.g. Pelox.
When cleaning stainless steel product with dedicated cleaning solution, one should pay attention
to the suggestions and recommendations given in the instruction manual or in the safety data sheet of the cleaning solution.
10.1. Exterior cleaning
1.
The housing of the device should be cleaned at least once a week, depending on the working conditions.
2.
The housing and door should be cleaned with caution using a soft cloth dampened with water.
3.
Only mild cleaning products should be used to clean the device.
4.
Electrical parts should not get in contact with water or detergent.
5.
Clean the touch screen using a soft cloth or a foam for cleaning touch screens.
6.

10.2. Interior cleaning
1.
Before cleaning the interior of the device, empty the chamber.
2.
Open the door of the device, if necessary wait till the chamber has cooled down, take out the shelves and start
cleaning of the device
3.
Only water or water with mild detergent should be used.
4.
Having finished cleaning, you should allow the device to dry fully and instal all parts removed before cleaning.
5.
During cleaning you should make sure not to damage the temperature sensors which are located inside the
79
Instruction manual ZLN, ZLN-T, ZLW-T, ZL-UT VIP SMART PRO
chamber.
At least once a month clean the condenser with a vacuum cleaner, dry cloth or a soft brush. Placement of the
condenser in the freezers it’s at the front in the bottom of the device. To access it, pull the ventilation cover (a)
towards you and then pull it up (b). After cleaning the condenser (1), install the cover.
6.
Failure to clean regularly may result in damage to the compressor and loss of the rights for repair
under warranty.
10.3. Cleaning the touch screen
The touch screen is exposed to dirt, so it must be cleaned regularly. To clean the touch screen, use a clean and dry
microfiber cloth. It is a very delicate material and collects dirt well.
Before using the cloth, make sure that on the surface there are no crumbs or particles. During
cleaning, they can act like sandpaper and scratch the surface of the screen.
If the stains cannot be removed by dry cleaning, the cloth can be lightly dampened with water.
Do not use paper towels to clean the screen as it may cause microdamages.
Before cleaning, lock the screen by pressing
on the top drop-down list (Figure 75).
