III. PACKAGE CONTENTS
- Commercial Refrigerator or Freezer
- Shelves (standard or as agreed)
- Two Keys
- Door handle with fixing screws (as per request)
- Instruction manual
We guarantee a fully functional, damage-free product at the time of packing.
In case of any transit damage, please contact your dealer immediately.

Before you begin the installation process, we would like to remind you that if the appliance
has been transported or stored in a non-upright position, please ensure to leave it standing
upright for approximately 12 hours before operation. This allows the refrigerant inside the
appliance to settle, ensuring optimal performance. Failing to follow these guidelines
could negatively affect the appliance's performance and lifespan.
APPLIANCE SETUP
1. Unpack the appliance: After removing the appliance from its packaging, make sure
all protective film and coatings are completely removed from all surfaces.
2. Location: Select a spot for your appliance where the floor is both level and firm. To
ensure adequate ventilation, maintain at least a 4-inch clearance between the unit
and any walls or other obstructions. If the unit is placed near a heat source, this
distance should be increased to avoid overheating.
Please remember to install the rubber spacer on the back of the appliance as
guided in the “Rubber Spacer Installation Section” (Page 8).
3. Pre-cleaning: Before the first use, thoroughly clean the interior shelves with soapy
water. This removes any residues from the manufacturing process and helps
maintain hygiene.
4. Securing the unit: If your appliance is equipped with castors, set the brakes to keep
it stable in its position. If it has adjustable screw feet, level the appliance by turning
these as needed.
Remember, these appliances should only be operated in environments with ambient
temperatures no higher than 90°F (32°C) as per Climate Class 4 specifications.
SHELF INSTALLATION
Your appliance is designed to offer flexibility in the arrangement of your items.
For your convenience, it comes with adjustable shelves that allow you to customize the
interior space according to your needs.
Here's how to install the shelves:
1. For Refrigerators: Your refrigerator comes with adjustable shelves that can be
placed in different plastic layers within the appliance. To adjust the height of a shelf,
carefully lift it and reposition it into the desired plastic layer.
2. For Freezers: In our freezers, the evaporator itself serves as shelves.
The number of these shelves varies depending on the model's capacity.
Be careful when handling the evaporator/shelves to avoid damaging the pipes with
excessive force.
3. Damage or Defects: If you notice any damage or defects with the shelves upon
delivery or during use, please contact your dealer immediately for assistance.
By tailoring the layout of your appliance to suit your needs, you can optimize its storage
capacity and efficiency. Please handle the shelves carefully during installation and
adjustment to prevent damage.

Proper operation of your Commercial Refrigerator or Freezer is essential for ensuring
the best performance and longevity of the appliance. This section provides detailed
guidelines on operation and door management for maximum efficiency.
STORING FOOD
The key to maintaining the freshness and quality of your food is proper storage.
Here are a few tips:
•Allow the appliance to reach its operating temperature before storing food items in it.
• Hot food or liquids should be cooled to room temperature before being placed in
the appliance.
• Wrap or cover food whenever possible to prevent the spread of odors and maintain
food quality.
• Avoid blocking the fans inside the appliance as they are essential for maintaining
consistent internal temperatures.
•Try to minimize the time the doors are open to reduce the loss of cold air.
DOOR OPERATION
Your appliance is equipped with a lock to secure the contents and maintain a stable
internal environment.
Here are a few tips:
•Locking the Door: Use one of the provided keys to lock the door when the appliance
is not in use. This is crucial in commercial settings for security and to maintain the
internal temperature.
• Unlocking the Door: To access the contents, insert the key into the lock and turn.
Always remove the key after unlocking the door and ensure the door is fully closed
after use.
TURNING ON THE APPLIANCE
1. Ensure the doors of the appliance are securely closed.

VI. DEFROSTING
5
Your appliance is equipped with an automatic defrosting feature that helps maintain
optimum cooling efficiency. However, there are instances when you may need to
manually initiate a defrost cycle.
AUTOMATIC DEFROSTING
- Your appliance will automatically initiate a defrost cycle every six hours.
- The cycle begins from the time the appliance is initially powered up.
- This automatic defrosting process contributes significantly to the optimal operation
of the appliance and should not be interrupted.
MANUAL DEFROST
There might be occasions where manual defrosting is necessary.
To manually defrost your appliance:
1. Press and hold the 'DEFROST' button for five seconds.
2. The defrost cycle will commence immediately, with the Defrost LED indicator
illuminating. This manual defrost cycle will continue for a maximum of 30 minutes.
Remember, initiating a manual defrost also resets the automatic defrost timer.
The next automatic defrost will start six hours after the completion of the manual defrost.
Proper defrosting is crucial to the efficient operation of your appliance. It helps maintain
ideal temperature and humidity levels, ensuring your stored items remain at their best
quality. Please ensure to follow the defrosting procedure as outlined above.

VII. CLEANING AND MAINTENANCE
Maintaining the cleanliness and overall performance of your Commercial Refrigerator or
Freezer requires regular cleaning and maintenance.
These practices not only ensure the appliance operates at peak efficiency but also
prolong its life and functionality.
GENERAL CLEANING:
1. Always disconnect the appliance from the power source before cleaning.
2. Frequently clean the interior with a gentle cleaning agent to prevent bacterial growth
and odor.
3. Do not use abrasive or harsh cleaning agents as they can leave harmful residues or
damage the surface.
4. Avoid using sharp tools which may damage the ABS plastic liner of the cabinets.
5. Clean the door seal with water only. Wipe dry after cleaning to prevent mold growth.
6. Do not let cleaning water run into the drain hole, as it could overflow into the evapo-
ration pan.
7. Be cautious when cleaning the rear of the appliance as it may have sharp edges.
CONDENSER CLEANING:
The condenser is an essential part of the appliance and should be cleaned every 30 days.
A clean condenser can extend the lifespan of the appliance.
We recommend having our service agent or a qualified technician perform this task.
Important Note: All repair and maintenance requiring the removal of panels or parts
should be performed by a service agent or a qualified technician.
Regular cleaning and maintenance practices are crucial for the longevity and proper
operation of your appliance. Remember, an investment in routine maintenance can save
you from costly repairs in the future.
