INSTALLATION: SKID REMOVAL / ALIGNING CASE / FRAME SUPPORT RAILS
1. Remove Unit From Skid
 Caution! To prevent damage, support case
while sliding skid out from under case.
 Note: Illustration below reflects general outline of
sample case and does not reflect any particular
model or options).
Carefully Slide
Skid Out From
Under Unit
2. Position & Align Case Alongside Others
 Before adjusting levelers, make certain that the
case is in proper position and, if required, aligned
with adjoining case(s).
 This may require repositioning of the case you
are installing or the already positioned case.
3. Frame Support Rails
 Illustration below shows case with frame support
rails (sample case - may not exactly reflect your
particular model).
 Shims will be provided with all cases that have
frame support rails.
 Use shims to level case.
 Note: After case is in position, it must be
sealed to floor to prevent entry or leakage of
liquid or moisture.

INSTALLATION, CONTINUED: SNEEZE GUARD ASSEMBLY SELF-INSTALLATION (RETROFITTING)
Sneeze Guard Self-Installation (Retrofitting)
 Cases may be ordered without sneeze guards.
 Should customer wish to attach sneeze guards AFTER
case has been delivered, it is the responsibility of
customer (and their chosen contractor) to do so.
 Structural Concepts is not responsible for damage to
case or sneeze guard as it pertains to methods
employed or components chosen in retrofit process.
 If your model is similar to model GP441RRLB (shown on
this sheet) do not use screws longer than 1” or they may
penetrate through top board and into electrical wiring
or heat tape. Each model may vary. Carefully check
panel thickness and surrounding electrical components
before drilling holes or attaching screws into your unit.
 Note: Model shown may not exactly reflect specifics of
your particular model or options.

CASE START-UP / THERMOMETER FUNCTION & LOCATION
1. Case Start-Up
 Case will energize when properly field-wired.
 Refrigeration system will supply cold air to rear drawers,
rear door compartment and front grab-n-go section upon
being energized.
 Front refrigerated section shown below. Light switch
(if any) will turn on light at front of case.
 When properly field-wired, coil fans should turn on. From
inside of the case, check for discharge air from the air
diffusing honeycomb to confirm that fans are functioning
properly. See next page for honeycomb location.
 When case is in start-up mode (or has been idle for a
long period of time), unit requires 75 minutes of run time
to pull-down temperature.
2. Thermometer Function & Placement
 Note 1: Thermometers provides temperature to three (3)
separate areas in the case.
 Note 2: Thermometers reflect warmest air temperature in
merchandiser. They do not provide actual food
temperature.
 Note 3: Use probe thermometers to determine actual
product temperatures.
