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.
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.

Requires manual verification that

FIGURE 8 — CHECK INSTALLATION OF LAMP WITH SHIELD
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.
