LEVEL UNIT UNPLUG CARTRIDGE POWER AND LIGHTING CORDS To provide adequate condensate drainage and proper door alignment and operation of unit, the unit cabinet must be level. Leveling feet are factory installed. Remove refrigeration system cartridge for easier access to back feet. Before servicing unit, disconnect electrical service. On sizes 1100L and 1300L, turn disconnect switch (located on power cord) to the OFF position.
INSTALL SHELVES TOP TAB FULLY INSERTED INTO SLOT Product shelves and a bag containing shelf support clips are packed inside the unit. Refer to Table 1 to verify quantity of shelves and shelf supporting clips. Bottom shelf must be placed on interior floor and should be inserted into the two retainer clips provided at the rear corners of the unit floor.
START-UP To achieve proper lamp engagement, rotate the lamp 90 degrees from its insertion position until it snaps or clicks into place. On units without safety shields, visually verify proper lamp installation by checking the identification mark on the end of the bulb. If the bulb has been properly installed, the mark will be centered between the “halves” of the lamp holder. Refer to Figure 7. On units with safety shields, the identification mark cannot be seen. (See Figure 8.
ELECTRICAL SUPPLY AND CONNECTIONS — Check to be sure that the electrical service to the unit meets all local and national electrical codes. Unit electrical data is shown in the unit data label, located on the inside of the cabinet in the upper lefthand corner. Review this label before initiating electrical service. Voltage range of power supply to unit should be 105 to 125 volts. Refer to Table 2 for unit data. NOTE: Other motors or heavy appliances should not be used on the same circuit with the cooler.
REFRIGERATION SYSTEM SERVICE SERVICE AND TROUBLESHOOTING CARTRIDGE REMOVAL COMPONENTS The Carrier Miracool™ refrigeration system consists of a hermetically sealed compressor and finned evaporator and condenser coils. Before servicing unit, disconnect electrical service. On sizes 1100L and 1300L, turn disconnect switch (located on power cord) to the OFF position. Failure to disconnect electrical service could result in electrical shock and cause personal injury or death.
CHARGING REFRIGERATION SYSTEM — Refer to Table 2 for refrigerant type and amount of charge. Since capillary tube systems have small critical refrigerant charges, it is recommended that a field charge either be weighed in or transferred from a portable charging cylinder. After maximum vacuum has been obtained as detailed above, attach charging cylinder to the system line making sure to purge air from hose with refrigerant.
