Start up should be performed only by
a qualified technician.
PRIOR TO START UP CHECKLIST
• Is the case connected to a power supply as
specified on the nameplate?
• Is the power on at the breaker panel?
• Are the doors properly torqued? Are they
self closing? Check each door from a fully
open position and from about a 1-inch open
positions.
• Are the evaporator fans plugged in? Do they
rotate freely? (The fans can be inspected by
lifting the deck pans in the bottom of the
cases. Manually rotate each fan to confirm
it is free and visually inspect to confirm that
each fan is plugged into its receptacle.)
• Verify that refrigeration line shutoff valves
are in the back-seated (open) position.

START UP CHECKLIST
• Once the case is considered ready for start up,
move the main switch.
This main switch is located at the rear of the
wireway on the top, left side of the case.
This toggle switch turns on the power to
the condensing unit, and all case electrical
components, including anti-sweat heaters,
lights and fans.
• Check the reading on the display; it should
be displaying the case temperature. The
display is located in the center of the front
of the facade above the doors. The displayed
temperature will show the merchandiser's
discharge air temperature.
• Listen for any unusual sounds or events. For
example: evaporator fan blade interference,
compressor trip on overload, or high head
due to excessive ambient temperature, circuit
breaker trip, etc.
• Check the fan at each door to ensure all
fans are running. The discharge air output
at the top inside front of the case should be
relatively even across the length of the case
(honeycomb area).
Excessive ambient conditions may cause
condensation and therefore sweating of doors.
Facility operators should monitor doors and floor
conditions to ensure safety of persons.
