START-UP AND OPERATION
Raise the Curved Glass
• To raise the front curved glass, grab the lift
handle extrusion on the bottom edge of the
front curved glass and lift up.
• Gas cylinders hold the glass open for hands
free access to the interior of the case.
Merchandiser Start-Up
• Turn on the main power. Switch is on the
control panel at the rear left hand side of
base. Supply power will start evaporator coil
fan(s), the front fan and the evaporator/
condensate pan. It will supply power to the
light switch and thermostat, (self-contained
units).
• From the front of the case, raise the deck
pans and check to see that the coil fans are
all functioning properly.
• On the top of the front panel a register di-
rects air flow provided by the front fans,
(front air flow is to prevent condensation
from forming on the curved glass). Check
across the top of the front panel to see if air
is discharging across the entire front of the
case.
• Turn on the lights. Light switch is in the rear
control panel. First time lighting may require
a short warm up period for the bulbs. Slightly
dim or a flickering of new bulbs is normal. If
lights do not turn on, check all of the raceway plugs. The lighting is wired in series so
all lights must be plugged in or receptacles capped in order for the case to light.
