START-UP
PRELIMINARY CHECKS
Before applying power to the unit, verify that all lamps have been properly installed and are fully engaged in the lamp holders. There are 2 lamps in the signboard and 2 inside the cooler.
CAUTION
Improperly installed lamps may cause damage to the lighting circuit. Carrier will not be responsible for equipment of component falilures or other damages or losses that arise as a result of improper lamp installation.
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 6.
On units with safety shields, the identification mark cannot be seen (See Figure 7). Verify manually that the lamp has been rotated and locked into place.

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. See Figure 1 for location of service cord.
DANGER
Before servicing unit, disconnect electrical service. Failure to disconnect electrical service could result in electrical shock and cause personal injury or death.
CAUTION
If an extension cord is necessary, use only three wire grounding type. The use of ungrounded cords or overloaded circuit voids compressor warranty.
