START-UP

PRELIMINARY CHECKS

„ BI-PIN FLUORESCENT LAMP INSTALLATION/

VERIFICATION — Before applying power to the unit,

verify that all lamps have been properly installed and

are fully engaged in the lamp holders. Sizes 750L,

1100L, and 1300L have 2 lamps, one in the signboard

and one inside the cooler. Sizes 260L and 300L have

one lamp inside the cooler.

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.) Verify manually that

the lamp has been rotated and locked into place.

Improperly installed lamps may cause damage to

the lighting circuit. Carrier will not be responsible

for equipment or component failures or other dam-

ages or losses that arise as a result of improper lamp

installation.
