冷藏展示柜怎么调温度：
根据具体情况调温。

1、正常天气，春秋季，可将温度档设置为2-4档，这样箱内温度为6-7度，满足日常所需。

2、炎热天气，环境温度高，可将温度档设置为1-2档，室内温度在0度以下，可更好的保鲜食品。

3、寒冷冬季，环境温度在10-16度时，可调至5档，环境温度低于10度，可调至6-7档，箱内温度可冷藏即可。

商家在设计冷柜时，将箱内温度控制在0度到10度左右，人们可根据具体需求设置，一般控制器分为5个档，不同档温度不同，数穿会越大，箱内温度越低。

春秋可将箱温调到3档，夏天可将温度调至1-2更加省电节能。

冷藏展示柜使用要注意什么：
1、热食物要冷却后再放入冷藏柜内，因为易让食物外冷内热，从而变质，达不到保鲜的作用。

而且冷藏柜内不可存放过多的食物，太满太紧不利于空气对流，还会增加机组的负担，从而缩短使用寿命。

2、食物生熟分开放，不能混放于冰柜内，并且按所需时间合理摆放。

而且不能将食物放在蒸发器上，要放在容器内，避免在蒸发器上结冰，难以取出。

3、鲜鱼、鲜肉等食品要用塑料袋封装，再放入冷冻室。

蔬菜、水果也要将外面的水分擦干才能放入，温度最好在0度以上贮藏为宜。

4、冷藏展示柜顶上是一层很薄的钢板，不可放置过重的东西，否则会影响冷藏柜的使用，还会影响使用寿命。

Floor and Countertop Load:The area on which the unit will restmust be level, free of vibration, and suitably strong enough to supportthe combined weights of the unit plus the maximum product loadweight.NOTE: If there is a question pertaining to weight load limits, consult thefactory at 1-800-621-8560.2. Clearance: There must be a combined total of at least 3” clearance onall sides of the unit.3. Ventilation:The air cooled self contained unit requires a sufficientamount of cool clean air. Ensure the cabinet holding the drop-indisplay case is properly vented. Avoid surrounding your display casearound other heat generating equipment and out of direct sunlight.Also, avoid locating in an unheated room or where the roomtemperature may drop below 55° F (13°C) or about 90° F (32°C). INSTALLATION CHECKLISTAfter the final location has been determined, refer to the following checklist prior to start-up:1. Check all exposed refrigeration lines to ensure that they are not kinked,dented, or rubbing together.2. Check that the condenser and evaporator fans rotate freely withoutstriking any stationary members.3. Plug in unit and turn on main on/off power switch.4. Allow unit time to cool down to temperature. If temperatureadjustments are required, the temperature control can be accessedthrough the hole on top of the unit.5. Refer to the front of this manual for serial number location. Pleaserecord this information in your manual on page 3 now. It will benecessary when ordering replacement parts or requesting warrantyservice.6. Confirm that the unit is holding temperature. Set controls to desiredtemperature for your particular ambient and altitude.7. Allow your unit to operate for approximately 2 hours before putting infood to allow interior of unit to cool down to storage temperature.NOTE: All motors are oiled and sealed.NOTE: FAILURE TO FOLLOW INSTALLATION GUIDELINES AND RECOMMENDATIONS MAY VOID THE WARRANTY ON YOUR UNIT.ELECTRICAL SUPPLY: The wiring should be done by a qualified electrician in accordance with local electrical codes. A properly wired and grounded outlet will assure proper operation. Please consult the data tag attached to the compressor to ascertain the correct electrical requirements. Supply voltage and amperage8 800-621-8560requirements are located on the serial number tag located inside the mechanical housing.NOTE: It is important that a voltage reading be made at the compressor motor electrical connections, while the unit is in operation to verify the correct voltage required by the compressor is being supplied. Low or high voltage can detrimentally affect operation and thereby void its warranty. NOTE: it is important that your unit has its own dedicated line. Condensing units are designed to operate with a voltage fluctuation of plus or minus 10% of the voltage indicated on the unit data tag. Burn out of a condensing unit due to exceeding voltage limits will void the warranty. 910 800-621-8560Randell has attempted to preset the cold controls to ensure that your unit runs at an optimum temperature, but due to varying ambient conditions, including elevation, food product as well as type of operation, you may need to alter this temperature.It is strongly recommended that the doors be kept closed when the unit is not in use and between rush periods. This is especially important in the summer and in kitchens exceeding 80° F. Do not leave the doors open for prolonged periods of time. Close after using.NOTE: Even though your drop-in display case was designed for heavy use, excessive door openings should be avoided in order to maintain proper cabinet temperature and eliminate the possibility of coil freeze-up.Your drop-in display case was equipped with a temperature adjustment control located within the cabinet on the front face of the evaporator coil.To adjust the temperature in refrigerated units:A. To lower the temperature:1. Turn the dial knob clockwise.2. There are numbers to indicate settings. Keep the arrow on theknob pointed within the numbered section of the arc.3. Turning it clockwise beyond the numbered section can result infreeze-up.B. To raise the temperature:1. Turn the dial knob counterclockwise.2. There are numbers to indicate settings. Keep the arrow on theknob pointed within the numbered section of the arc.3. Turning it counterclockwise beyond the numbered section willshut the compressor off.NOTE: It is not recommended to turn the dial above 8 or below 1 on the temperature control. If the adjustments still do not resultin proper temperature please contact the factory at 1-800-621-8560.C. If your temperature control is at the maximum setting and the cabinettemperature still remains too low or too high, you may need to adjust the pressure control if your display case is equipped with one.1. Turn the right adjustment screw clockwise (1/4 turn at a time) toa lower number for a colder temperature.2. Turn the right adjustment screw counterclockwise (1/4 turn at atime) to a higher number for a warmer temperature.NOTE: Numbers on pressure control are pounds of pressure, not degrees F.NOTE: Do not adjust the differential screw.Randell strongly suggests a preventive maintenance program which would include the following Monthly procedures:1. Cleaning of all condenser coils. Condenser coils are a critical component in the life of the compressor and must remain clean to assure proper air flow and heat transfer. Failure to maintain this heat transfer will affect unit performance and eventually destroy the compressor. Clean the condenser coils with coil cleaner and/or a vacuum, cleaner and brush.NOTE: Brush coil in direction of fins, normally vertically as to not damage or restrict air from passing through condenser.2. Clean fan blade on the condensing unit.3. Clean and disinfect drains with a solution of warm water.4. Clean and disinfect drain lines and evaporator pan with a solution of warm water.5. Clean all gaskets on a weekly if not daily basis with a solution of warm water and a mild detergent to extend gasket life.NOTE: DO NOT USE SHARP UTENSILS.RECOMMENDED CLEANERS FOR YOUR STAINLESS STEEL INCLUDE THE FOLLOWING:JOB CLEANING AGENT COMMENTSRoutine cleaning Soap, ammonia, detergentMedallionApply with a sponge or clothFingerprints and smears Arcal 20, Lac-O-Nu,EcoshineProvides a barrier filmStubborn stains and discoloration Cameo, Talc, Zud, FirstImpressionRub in the direction of thepolish linesGreasy and fatty acids, blood, burnt-on foods Easy-Off, Degrease It, OvenAidExcellent removal on allfinishesGrease and Oil Any good commercialdetergentApply with a sponge or clothRestoration/Preservation Benefit, Super Sheen Good idea monthlyReference: Nickel Development Institute, Diversey Lever, Savin, Ecolab, NAFEM.
