Handle with care:

Unplug the wall socket first.

Never tilt it over 45 degrees during handling.

Dry place:

Always locate the refrigerator at a dry place.

Sufficient space:

The distance from both sides and back of refrigerator to the wall or other surfaces must be not less than 10cm. The refrigeration capability might be decreased if its surrounding space is too small to allow air to circulate.

Ventilation:

Always locate the refrigerator at a place with good ventilation. For the first time use, wait 2 hours after handling and then plug the wall socket and start it.

Keep far from heat sources:

Never place the refrigerator directly under the sunlight. Never locate it near any heat source or heater to prevent it from reducing refrigeration capability.

No heavy load:

Never put any heavy load on top of the refrigerator.

Do not perforate:

Never make holes in the refrigerator. Never install other matters on the refrigerator.

Stable location:

Unpack and install the refrigerator on a flat and solid place.

Exclusive power socket: The power supply socket should be 115V 60HZ with single-phase power supply. The power receptacle must have a reliable ground connection.

No shared socket: Never let the refrigerator share the electrical socket with any other appliance, otherwise the cable may become hot and cause a fire risk.

To protect the cables, never break or damage the cables to avoid current leakage and fire risk.

To prevent electrical shock, never wash the refrigerator surface with water.

Keep flammable and explosive materials away from the refrigerator. Never put any flammable or explosive product inside the refrigerator such as ether, gasoline, alcohol, adhesives, or explosives.

Do not use sprays near the refrigerator. Do not spray any flammable materials as paint or coating near the refrigerator to avoid the risk of fire.

After a power outage or after unplugging the refrigerator, always wait at least 5 minutes before plugging the refrigerator and starting it again.

Do not store medicines inside the refrigerator.

1. Notice

It is necessary to keep the appliance clean and perform periodical maintenance.

Ensure the appliance is unplugged before cleaning.

Never use a damaged plug, or loose socket to prevent electronic shock or short circuit.

Never flush the appliance. Never use alkali detergent, soap, gasoline, acetone, or brush to clean.

2. Clean outside

Clean the outside with a soft, damp cloth and some mild detergent. Then dry and wipe with a soft cloth.

3. Clean inside

Take the racks out for cleaning with water.

4. Shut down refrigerator for a long time

If the appliance will not be used for several months, remove all items, and turn off the appliance. Clean and dry the interior thoroughly.

The glass breaks easily. Keep the glass away from children.

Plug the refrigerator into a 115V exclusive socket. After it is running, put your hand on the air suction to confirm it is cold enough. Then you can put food inside the cabinet.

Adjust the racks positions according to your need and the size of the products displayed.

To adjust:

1. Remove the rack.

2. Place the rack support in the position desired and press it down to adjust.

3. Replace the rack on the support.

Air inlet: To allow the circulating air to return to the refrigerator, do not block the air inlet.

Air outlet: Do not block the air outlet to allow the normal air flow.

This electronic digital temperature controller is an integrated intelligent controller.

The main functions are temperature display, temperature control, manual defrost, illumination control, parameter setting and parameter locking.

Press the SET button, the set temperature is displayed and flashing. Press △ or ▽ to modify and store the displayed temperature. Then press the SET button to exit. If no button is pressed within 10s, it will show the inner set temperature.

Press the light bulb button to turn the light on or off.

Press and hold the defrost button for 6s to defrost or stop defrost.

Press the △ button for 6s, It will flash and show the temperature of the defrosting probe. It will show the inner temperature after 10s.

During refrigeration, the LED is on. When the cold room temperature is constant, the LED is off; During the delayed start, the LED flashes.

During defrost, the LED is on. When it stops defrosting, the LED is off.

Press the ▽ key for 10s, the display will flash “OFF” to show it is locked and will show “ON” to indicate it is unlocked. If the parameters are locked, they can only be viewed but cannot be changed, only the temperature adjustment is effective (factory default setting is OFF).

If there is condensation on the surface of the glass, and it is not allowed to manually proceed, stop the defrosting button.

Manual defrosting is only used to deal with the frost that may appear on the evaporator. After a long period of use, there will be frost generated on the surface of the evaporator, and the appliance may not work normally. To defrost the appliance, either set manual defrosting or wait for the product to automatically defrost.

All the parameters of the product have been debugged and locked before leaving the factory. No need to adjust the parameters of the temperature control setting for normal use to prevent the product from not working properly or affecting its functionality.

The causes and solutions for the PREMIUM LEVELLA PRNT217DX/PRNT297DX 4-Sided Glass Refrigerated Display Case not cooling are:

The refrigerator is not plugged in. Plug the refrigerator.

The circuit breaker tripped, or a fuse has blown. Replace the fuse or breaker by a qualified electrician.

There is air coming from the front air outlet but not cooling – and the pipeline is obstructed or leaking. Call for service.

There is no air coming from the inside air outlet – the evaporator fan is broken and does not work. Call for service.

The causes and solutions for the PREMIUM LEVELLA PRNT217DX/PRNT297DX 4-Sided Glass Refrigerated Display Case not being cold enough are:

Excessive dust in the condenser. Check and clean the condenser.

Insufficient air volume from the outlet, evaporator is obstructed. Defrost

Close proximity to heat source or direct sunlight. Move away from direct sunlight.

The door is not shut properly or is open excessively. Do not open the door too frequently.

Inadequate ventilation. Check air inlet and outlet.

Damage to the seal. Replace the seal.

Recently added a large quantity of warm contents to the cabinet. Wait for all products to cool.

Air suction or exhaust vent is obstructed. Check air inlet and outlet.

The checks for the PREMIUM LEVELLA PRNT217DX/PRNT297DX 4-Sided Glass Refrigerated Display Case making a big noise are:

Verify the appliance level.

Check if the appliance touches the wall or something else.

Is any part of the appliance loose?

The following are not troubles but common phenomena:

Sound, the refrigerant flows inside the cooler.

If the ambient humidity is high, there may be dew drops on the appliance surface, please use a soft and dry cloth to clean it in time.

The principle of compression refrigeration consists of “compression”, “condensation”, “throttling” and “vaporization”. The compression is undertaken by the compressor, the condensation is completed by condenser., The throttling is executed by the capillary and the vaporization is implemented by evaporator. When the coolant is circulating in the closed refrigeration system, the compressor sucks coolant, which then absorbs heat in the evaporator, the coolant reaches a high pressure and high temperature gas. In the condenser, it dissipates the heat in the air, while the coolant is re-liquefied and throttled in the capillary and then enters into the evaporator with low pressure. The liquefied coolant quickly boils and vaporizes into gas when the pressure suddenly drops. Meanwhile, it absorbs heat inside the refrigerator and the compressor sucks the low pressure and low temperature gaseous coolant. It circulates in this way until reaching the intended refrigeration.

The major parameters for the PREMIUM LEVELLA PRNT217DX and PRNT297DX models are listed in the table below:

The ambient temperature and humidity conditions of the show case climate class follow the table below:

NOTE: The water vapor mass of dry air is one of the main points influencing the performance and the energy consumption of the cabinets. Therefore, the order of the climate class in the table is based on the water vapor mass column.
