ASSEMBLING SINGLE DOOR COOLER / THE INITIAL START-UP

Air circulation at the rear is required for the coolers to operate efficiently. Move the cooler backwards to place it properly. Allow a minimum 10cm of space from the sides and the rear in order to ensure proper air circulation. Leva the top of the cooler free. For models S88SC and S56SC, allow minimum 10cm of space from the rear and minimum 30cm of space from the sides for proper air circulation. Your cooler is now ready to plug in.

OPERATION

Avoid blocking air circulation inside the cooler, when loading the cooler with products. Otherwise undesired and extensive temperature variances may occur between the top and bottom compartments of the cooler.

• Control panel:
  The Control panel consists of the following components depending on the model:

• Greenlight (optional):
  It is lit so long as the cooler is connected to the electric supply.

• Thermostat setting knob (optional):
  It is used to regulate the internal temperature of your cooler.
  Thermostat adjustment is the most optimum adjustment in products with a mechanical thermostats in factory defaults. It is recommended not to be replaced as long as it is not troubled with the internal product temperature. If you think that the product is not in desired temperature range you can make a thermostat adjustment.Thermostat setting must be done according to the features of the products to be preserved. Temperature setting can be done by means of turning the black thermostat knob on the control panel by the help of a coin or similar object. Turning the knob right decreases the internal temperature, whereas turning it left increases the internal temperature. Turning the knob left stops the compressor, which in turn stops the chilling process, although the electric current to the cooler is not cut off.

• Internal ventilation fan switch (optional):
  It used to provide air circulation inside the cooler.

• Internal lighting switch (optional):
  It is used to turn on or off the internal light of your cooler. If the light bulb does not function anymore, always unplug the cooler from the mains before replacing it. Pull up the lamp cover. Rotate the electric bulb 90 degrees, take it off and replace it with a new one. Always replace the starter whenever you replace the electric bulb.

Canopy lamps and inside lamps of S88SC and S56SC can be replaced only by skilled persons.

Dismantling the illuminated advertisement panel
If it ever requires dismantling the illuminated advertisement panel, do the following:
The LEFT lid is screwed to the body and it is not possible to dismantle it from the outside. Therefore do not try to remove it. Advertisement panel is fixed to the RIGHT lid. Hold the right lid on the top and bottom sides and pull it RIGHTWARDS. The right lid will slide on the upper and lower tracks allowing the compartment to open. Once the compartment is open, carry out the needed (replacing the florescent lamps) and close the compartment by pulling the lid in the opposite direction.

Replacing the fluorescent lighting: (if your product has a fluorescent lamp)
Before dismantling the lamp, always unplug your cooler. After dismantling the lamp cover inside the cooler, remove the lamp and always replace it with a lamp of the same features (length, power, etc.)

WARNING:
Your cooler can have a fluorescent lamp. If the fluorescent lamp doesn’t illuminate or start blinking, please call technical service to repair it in a short while. Please do not remain your cooler whit non-working lighting system. Your cooler can have a LED illumination. If you face any problem with LED illumination, never try to repair it yourself. Inform an authorized service.

Mounting the shelves:
There are 5 shelves provided with the models 7464.0085, 7464.0090, 7464.0095, D148, SC505TF; 3 with S240SC; 2 with S149 and S88SC; and 1 with S56SC. First insert the uppermost shelf in the uppermost hooks in the body. Insert the others correspondingly with the same method. Chilling process in the body takes place through the internal air circulation. Therefore do not place the shelves very close to one another.

For models SC505HP, SC505 STD, SC600, S650:
There are 5 shelves and 20 shelf supports shipped inside the cooler. Carry out the following to mount the shelves.

• Pilasters are numbered to provide height adjustment between the shelves in line with the product requirements. Place the shelf supports into corresponding notches on the pilasters. For an easy placement, use a pair of pincers to grip the support ends.
• Lay down the four shelves on the cooler floor. (Make sure that the right-angled (90°) side is at the rear).
• Hold the uppermost shelf; tilt one side and place on the hooks on the corresponding supports.
• Do the same for the remaining shelves and mount them all.

Removing the pallet and inserting the feet
Your single door cooler has been delivered on a wooden pallet, screwed to the body at four corners. Please carry out the following to detach the pallet before the body is set in its final operation location:

• Cut the 4 cable ties fixing to pallet to the cooler chassis by the means of a hand tool (except to S56SC and S88SC).
• Use a wrench to loosen and remove the head screws on the front and rear corners that fix the pallet to the base (only for S56SC and S88SC).
• Carefully detach the pallet from the body base. Please find the feet of the cooler provided interior. Insert them in the screwed sockets at the bottom of the cooler and make the height adjustment.

Defrosting:
Your cooler is devised with an automatic defrosting system regulated by the thermostat. Defrost water accumulates in the channel underneath the evaporator; it is then carried to the drip tray by the help of a hose where it evaporates.
You can speed up defrosting by means of placing a bowl of hot water underneath the cooler (make sure that it is not boiled). After defrosting, clean the body and make sure to wipe it out leaving no moist inside. Plug the body again and reload the cooler after one hour.

CLEANING, MAINTENANCE AND TRANSPORTATION

To ensure higher efficiency, your cooler must be regularly cleaned. Never use any cleaning agent that contains alcohol, scouring powder or powerful solvents. Always remove the plug from the mains socket before cleaning the cooler. Add two teaspoons of baking soda (bicarbonate of soda) in 1 liter water and use the mixture to clean the cooler. Clean the outer part with a wet cloth and then wipe it out.
Attention: never use any hot water, electrical heater, sharp tools or similar things as they may ham the cooler.

Holidays/stop using for a while:
Do not unplug your cooler if you are going on a holiday or stop using it for a short time. If you are going on a holiday or stop using the body for a long time, unplug the cooler and empty it. After defrosting, clean the cooler and wipe it out with a cloth. Leave the door open to prevent odour in the cooler.

Transporting your cooler:
Before relocating the body, unplug it from the mains socket, defrost it, wipe the interior walls and floor with a damp cloth, place the plastic blockings between the glass door and the body and carry it in the normal position as it is used.
Attention: expansion gas (C-Pentane) is used in the insulation system of the cooler. When you dispose the body, it requires observing the applicable laws and rules of the country in which it is used. Cleaning / maintaining of your cooler’s condenser must be done at least two times in a year by authorized service.

FOR MODEL WITH ELECTRONIC CONTROL SYSTEM

Our models with electronic control are designed with purpose of minimizing the energy consumption, and for that purpose they are equipped with special control systems. Your product is not only with thermostat control, it is equipped with a control system having feature of self-learning. It is unfavourable to mount and dismount the magnetic door switches, motion sensor and other equipment by unauthorized people. Control system is set so that refreshments should be kept at 3°C. This temperature value is the plant set temperature so that you can get the optimum efficiency from the cabinet and the ideal temperature recommended by refreshment producers.

Operating mode of electronic control system
The most important feature of the system is the self-learning module. It can sense conditions of the usage and when the selling point that the product is placed, is open or closed and it can control the operation characteristics in this direction. This features are provided by recording the properties as the density of the people around the cooler, frequency of opening and closing of the door of the apparatus, light level of the environment where the cooler is inside, with the help of the sensors.

Features that can be controlled by the control system
Control unit can open the lights of the cooler when the selling point is open and shuts off the lights when the selling point is closed. This feature shall operate after finishing the learning period of the control system. The light of the cooler shall be open until finishing the learning period. Please do not try to close it by yourself.

Control unit can control the inside evaporator fan. When the door is opened, inner fans are stopped. When the equipment is in stand-by mode, inner fan operates and stops with certain intervals. Stand-by mode refers the night or the hours that cooler is not used. When the door of the unit is open for more than 2 minutes, control unit give signal. For this reason, it is normal to have signal during the loading of the refreshment. When the loading is finished, signal stops with closing of the door.
In stand-by mode control unit can lower the operation period of the compressor to the minimum levels. Control unit applies defrost periods in certain intervals and it stops cooler system completely. After defrost operation, system turns normal condition again. If there is a cooling defect in your cooler, control unit gives an alarm.

Operation steps
Start your cooler in morning hours and in working hours. It is important that the energy should not shut down during 48 hours. Control unit shall start to learn working hours of the place it is in, and the operation characteristics of the cooler from the first day it operates. When the control unit can identify a stabile characteristic under operating conditions, it starts to control the cooler. This period is between 2 and 10 days. When the learning mode is completed, control unit shall start stand-by mode after selling point is closed and after 30 minutes it shall turn off its lights. The next day, 3 hours before the opening of the shop, it shall pass to normal operating condition in order to keep the refreshments inside ready.
Important note:
Control unit shall compare the product using characteristic that is recorded and taken as reference with variable using characteristic continuously. In direction of periodic changes as seasonal changes and change of opening and closing hours of the shop, it shall learn and modify the program according to new conditions and control the cooler continuously. Absolutely do not close the front part of the motion sensor otherwise cooler shall not sense the using frequency of the cooler.

Operation and screen information:
COMPRESSOR (compressor light): if green light is on, it shows that compressor is active.
FAN (fan light): if green light is on, it shows that inner fans are active.
