PREMIUM PRN530DX (01) PDF MANUAL

Please read through the manual in its entirety before installation. The following steps are important:

• If the unit has recently been transported, please let the unit stand still for a minimum of 24 hours before plugging it in.

• Make sure that the unit drops down to the desired temperature before loading the unit with product.

• Make sure that there is proper ventilation around the unit in the where it will operate.

• Make sure all accessories are installed before plugging the unit in.

Install the unit on strong and leveled surfaces:

– The unit may make unpleasant noises if the surface is uneven.

– The unit may malfunction if the surface is uneven.

– If the floor is not flat, please use something to make sure the base of this unit is on a horizontal level.

Install the unit in an indoor, well-ventilated area:

– The unit performs more efficiently in a well-ventilated area.

– For best performance, please maintain a clearance of 10 cm on the back of the unit, 30 cm on the top of the unit, and at least 10 cm space around the unit.

– Outdoor use may cause decreased efficiency and damage to the unit.

Avoid installation in a high humidity and/or dusty area:

– Humidity could cause the unit to rust and decrease the efficiency of the unit.

– Dust collected on the condenser coil will cause the unit to malfunction. Clean the condenser at least once a month with a brush or clean cloth.

Select a location away from heat and moisture-generating equipment:

– High ambient temperature will cause the compressor to overwork, leading to higher energy bills and gradual breakdown of the unit.

Other Guidelines:

– The appliance shall not be exposed to rain or sun.

A. Hook shelf clips onto the clip hanger.

B. Place shelves on the shelf clips, making sure all corners are seated properly.

C. Hook the plastic frame of the price tag on the shelves.

Note: Remove the glass door bracket from the door before use.

Castor or adjustable feet are available for the units.

Adjustable feet: These can be adjusted to level the unit.

Castor with brake: The castor has a brake. Turn it to a different side to lock or unlock the castor.

Please ensure that the required voltage of the compressor is being supplied at all times. Please refer to the electrical requirement on the nameplate. CAUTION: Low or high voltage can detrimentally affect the refrigeration unit.

All units should be plugged into a grounded and properly-sized electrical outlet with appropriate overcurrent protection. This unit may be equipped with a NEMA 5-15P or NEMA 5-20P plug.

If you do not have the right outlet, have a certified electrician install the correct power source.

Please make sure that your unit has its own dedicated outlet. Do not use an extension cord.

After proper installation, please plug the cord in and turn on the power switch.

• To minimize personal injury, do not hang on the doors.

• Do not store any flammable and explosive gas or liquids inside the unit.

• Do not attempt to alter or tamper with the electrical cord.

For efficient operation, it is important that the condenser surface be kept free of dust, dirt, and lint. WARNING: Disconnect the power cord before cleaning any parts of the unit.

• We recommend cleaning the condenser coil and fins at least once per month.

• Clean with a commercial condenser coil cleaner, available from any kitchen equipment retailer. Brush the condenser fins from top to bottom, not side to side.

• After cleaning, straighten any bent condenser fins with a fin comb.

WARNING: Disconnect the power cord before cleaning any parts of the unit.

CLEANING THE FAN BLADE AND MOTOR

If necessary, clean the fan blades and motor with a soft cloth. If it is necessary to wash the fan blades, cover the fan motor to prevent moisture damage.

CLEANING THE INTERIOR OF UNIT

• When cleaning the cabinet interior, use a solvent of warm water and mild soap.

• Do not use steel wool, caustic soap, abrasive cleaners, or bleach that may damage the stainless steel surface.

• Wash door gaskets on a regular basis, preferably weekly. Simply remove the door gasket from the frame of the door, soak it in warm water and soap for thirty (30) minutes, dry with a soft cloth, and replace.

• Check door gaskets for proper seal after they are replaced.

• Periodically remove the shelves and pilasters from the unit and clean them with mild soap and warm water. To remove the pilasters, first remove the shelves and shelf brackets. Then, simply lift the pilaster up and out.
