    INSTALLATION HOW TO INSTALL YOur OuTdOOr rEFrIGErATEd drAWEr 2.9 Select location The proper location will ensure peak performance of your appliance. Choose a location where the unit will be out of direct sunlight, away from heat sources and moisture. Units with fan cooled condensers can be built in. Unit should be operated in a properly ventilated area with ambient temperatures above 40 degrees and below 100 degrees Fahrenheit.

    INSTALLATION ANTI-TIP INSTALLATION INSTruCTIONS A free standing refrigerated drawer must have an anti-tip device installed as per these instructions. If the drawer is removed from its location for any reason, make sure that the device is properly engaged when you push the drawer back into the original location.

    INSTALLATION ANTI-TIP INSTALLATION INSTruCTIONS 2.14 wall moUnt To Drawer 1. Remove the bracket from its original shipping position on the back of the Refrigerator unit (Fig. 2.9 and 2.10). 2. Reattach the bracket to the back of the unit using the existing screws from the unit’s back panel (Fig 2.11).

  • Page 13: Sealed System

    Use a leak detection system that will detect R-134a refrigerant. Leaks need to be found on any leaking system BE- FORE the repair takes place. The drier must be replaced anytime the sealed system is opened. Always use a DCS drier. Failure to do so may cause repeated system failure in the future.

  • Page 14: Evaporator Frost Pattern

    SEALEd SYSTEM 3.6 evaporator froSt pattern Checking the evaporator frost pattern is a good way to quickly diagnose simple sealed system problems. This can be done by allowing the unit to run (at least 10 minutes) with the door open for at least 5 minutes. This will help speed up the normal frosting of the evaporator plate.

    SEALEd SYSTEM COMPONENTS 4.1 gaining acceSS to mechanical BaSeplate The mechanical baseplate is located in the rear of the unit. Most major mechanical and electrical components on the unit mount directly to the baseplate. This creates easy access for servicing of the sealed system and mechanical/electri- cal components.

  • Page 17: Compressor

    SEALEd SYSTEM 4.2 compreSSor The compressor is the heart of the refrigeration system (see Figure 4.4). However, it relies on other parts of the system to function. Make certain that the other parts of the system are functioning correctly before determining that the compressor is faulty. Compressor Drier Figure 4.4...
  • Page 18 SEALEd SYSTEM Installing the Compressor: Install the four rubber grommets in the bottom of the new compressor and install the three sleeves where the carriage bolts will be located. Mount the new compressor and install the three washers and lock nuts and tighten to 45 in-lbs. DO NOT REMOVE THE RUBBER PLUGS AT THE TUBE STUBS ON THE COMPRESSOR AT THIS TIME.

  • Page 19: Condenser

    SEALEd SYSTEM 4.3 condenSer The condenser is a steel tube serpentine with copper alloy fins that removes heat from hot, high pressure vapor from the com- pressor (see Figure 4.8). The most common trouble is lack of airflow from either a restricted intake or exhaust opening in the front of the unit.

  • Page 20: Evaporator

    (see Figures 4.9). The RF24D uses a vertical right angle evaporator plate. It is normal for the evaporator to frost up during its run cycle. This frost will dissipate once the unit reaches its “cut out” tempera- ture and the compressor and fan stop.

  • Page 21: System Components

    SYSTEM COMPONENTS 5.1 condenSer fan The condenser fan is used to force air over the condenser coil. The fan will cycle on and off with the compressor which means that when the compressor is running so is the fan and when the compressor is not running neither is the fan (see Figure 5.1). Figure 5.1 To check the condenser fan: •...

  • Page 22: Thermistors

    SYSTEM COMPONENTS 5.2 thermiStorS The refrigerated drawers utilize two thermistors: one is known as the evaporator thermistor and the other as the display thermis- tor. Each thermistor has a different function for input to the electronic control. Evaporator thermistor: The evaporator thermistor turns the unit on and off. It is secured to the evaporator or cabinet liner. Display thermistor: The display thermistor is connected to the LED display and displays the temperature inside the unit on the display panel.
  • Page 23 SYSTEM COMPONENTS Removing the Evaporator Thermistor: Disconnect power. Remove back panel and lower shroud. Disconnect the evaporator thermistor connector at the electronic controller. Remove evaporator thermistor by removing the screw securing it. Feed the thermistor wire out through the opening in the back of the unit. Installing the Evaporator Thermistor: Reverse the removal procedure for installation (see above).
