Usage
Setup
The freezer must be set up by an authorized person. In the settings menu the correct code must be entered
so that the items below become visible.
1. SETPOINT : The temperature that the controller is set to achieve [SetPoint]
2. T DIFF : The difference between the SetPoint and the temperature that causes the fan and
compressor to restart
3. ALARM LO : SetPoint [value] set off Alarm Lo
4. ALARM HI : SetPoint + [value] set off Alarm Hi
5. AL.DELAY : Delay before Alarm Hi/Lo is activated
6. MAX ROOM : Maximum room temperature before room temp alarm is given
7. CPRTIMER : Minimum time between each compressor startup
8. CHANGE CODE : Change the access code
Usage
When the freezer has been setup and the freezer is in auto mode, it will operate in accordance with these
settings. When settings are changed the freezer will use the new settings immideatly after.
The controller will now try to cool the freezer to the SetPoint. When this is reached the fan and compressor
will stop. When the freezer temperature rises above SetPoint - TDiff they will start up again.
Please note that the fan will run 15 seconds before and after the compressor.
Manual mode
A person with the correct access code will be able to operate the controller manually. Select MODE-
>MANUAL to put the freezer into manual mode. From SERVICE->MANUAL->[Menu] the operator is now
able to turn on/off the compressor, fan, light, CTS, Battery Charge and Buzzer. When manual control is
finished the operator must select MODE->AUTO again to cancel manual mode. There are no regulation
or safety features of any kind active in manual mode. Please note that this mode is only for
trouble shooting.
Note that the control system does NOT return to AUT-mode automatically.
Calibration of sensor
The temperature sensor of the freezer can be calibrated. Before this the temperature must be stable.
Therefore this menu item is not active until the freezer has settled on the SetPoint for one hour as a
minimum.
Description of the calibration procedure.
Enter a calibration value in SETTINGS -> CALI. This value represents the offset from the SetPoint.
The LMC260 now controls the freezer according to SetPoint +/- this value.

The Cooling System
The vaporiser is built into the shelves of the inner container. They will be approx. -85°C, so there is a risk of
frostbite if they are touched. Always use thermal gloves when touching the contents of the freezer.
The condenser is placed on top of the cabinet behind the control panel.
Thermostat with digital display: once the freezer is cooled down, the set temperature and the temperature
shown will be the same.
CO2 Back Up
2
4 x port holes are prepared for CO back up, and an injection tube (see separate enclosure) can be inserted
2
from the top of the unit (remove kit). Make sure that pressurized CO escape from the gaskets or pressure
valve.
Service with for - °C freezers
Note that the EP88 gas can only be filled from a bottle containing a measured amount. Normal procedures
used in conjunction with other refrigerants cannot be used.
Further note that the freezing capability is very dependent upon filling the entire contents of the bottle into
the system. Freezing capability is also very dependent upon the temperature of the EP88 and whether it
has been still for a long period of time. The temperature of the service bottle must be between 8 and 14
degrees and the contents mixed by shaking the bottle 10-15 times.
In order to carry out the service procedure correctly, it is necessary to use a capillary pipe with mounting
screws between the bottle and the filling station instead of a normal filling hose. The service technician may
do this by using the mounting screws of a normal filling hose onto a capillary pipe.

11
Filling procedure:
•Empty the system and evacuate to 2 mbar. Evacuation must be performed at two places in the
system; both from the filling pipe and from the pipe mounted on the pressure side of the compressor.
•Mount the capillary pipe with mounting screws between the filling station and the service bottle.
•Unlike with other refrigerants, the service bottle must be turned tap-down.
•Commence filling.
•The compressor will start after approx. 10-15 seconds of filling.
•The bottle is empty when the pressure falls to 1bar and must be shut immediately. Immediate
shutting of the bottle is very important to prevent the fluid being pushed back into the bottle.
•Close the system.
Relocating or Moving the Freezer
Never leave the freezer to others without instructing those people in its use and the safety regulations
described in the operating instructions. Always let an authorised electrician install the freezer. (Remember to
wait for one hour before restarting it).
If the freezer and its electrical parts are reconstructed, the guarantee and safety regulations shall cease to
apply.
•If the freezer does not work: call an authorised servicing engineer!
•Contact the distributor or an authorised service repair shop!
•It is not recommended to lay down the unit. Please let the unit rest in vertical position for minimum 12
hours before start up.
Cleaning and Maintenance of the Freezer:
•Ice will form on the inner doors of the freezer. This ice should be removed with a scraper at regular
intervals. (Remember safety gloves).
•Ice on the inside of the cabinet should be removed as required. Take the contents out of the freezer.
Pull out the plug and leave the door open until the ice can be removed. (Remember safety gloves).
•Dry the inner cabinet and shelves with a cloth until it is not damp any longer.
•For external maintenance use stainless steel polish.
•Ice formed on the inside of the door should be removed with a wooden/plastic scraper. This ice will
build up because of the low temperatures inside the cabinet, and if it is not removed it will cause the
door to open.
•Cleansing agents containing chlorine or compounds of chlorine as well as other corrosive means
may not be used as they might corrode the stainless panels of the cabinet and the evaporator
system.
•The compressor compartment and in particular the condenser must be kept free from dust and dirt.
This is best done with a vacuum cleaner and a brush.
Do not put bottles containing carbonic acid or inflammable products in the freezer.
Disposal and scrapping of the freezer: Remove the lock, so that there is no risk of children getting locked in
the freezer whilst playing.

12
Note
Unplug the appliance before carrying out maintenance.
Do not use abrasive products; stain removers (e.g. acetone, trichloroethylene) to clean the appliance.
Spare parts
When ordering spare parts that you can easily fit yourself, please give unit type number and the function of
the part(s) concerned.
Disposing of the Freezer
To prevent harmful environmental effects, contact the distributor and ask where the freezer should be
delivered.
Remove the locking function so that children cannot be locked in the freezer whilst playing.
You can obtain information on the disposal of refrigeration appliances from:
•Your supplier
•Authorities (The Local council, Ministry of the Environment, etc.)
