is strongly recommended.
CAUTION
CAUTION! POWER CORD AND PLUG MAINTENANCE
Risk of electric shock. If cord or plug becomes damaged,
replace only with cord and plug of same type.
CAUTION! ADVERSE CONDITIONS / SPACING ISSUES
Performance issues caused by adverse conditions are NOT warranted.
Unit must be kept at least 15-feet from exterior doors, overhead HVAC
vents or any air curtain disruption to maintain proper temperatures.
Unit must not be exposed to direct sunlight or any heat source (ovens,
fryers, etc.).
Keep at least 8-inch clearance above unit for air discharge
(self-contained units only).
CAUTION! CHECK CONDENSATE PAN POSITION & PLUG
Water on flooring can cause extensive damage!
Condensate pan MUST BE positioned directly under
Before powering up unit, check the following:
condensate drain.
Condensate pan plug MUST BE securely plugged into
receptacle.
Check that overflow pan is fully functional.
If wicking material is used, check that it is secure.

CASE REMOVAL FROM SKID (LEVELERS OR CASTERS)
1. Removing Case Shipping Brackets That Are Attached To Skid
Remove screws holding Case Shipping Brackets to skid.
Remove Case Shipping Brackets from Skid.
See illustrations below. Note: Shipping Brackets will vary in size, shape, material and location
depending upon case type and model.

2. Remove Case (With Levelers) From Skid
To prevent damage, support case while sliding
it toward edge of skid.
When case is at edge of skid, carefully lower to
floor (so two levelers rest on floor).
Carefully slide skid out from under case.
After removal of case from skid, place into
position.

INSTALLATION - CAULKING AND BOLTING UNITS TOGETHER
Installation
Note
: Units shown may not depict an exact
representation of your particular unit being installed.
A
1. Position and Level Units
Position Units. Align multiple units carefully in
areas A, B, and C.
See illustration at right.
2. Ventilation and Clearance
Self-Contained refrigerated cases must
maintain airflow clearance of 6” (minimum) to
12” (recommended) at front and rear.
Restriction of air can void warranty.
Illustration at top-right may not reflect every
feature or option of your particular case.
3. Caulking and Bolting Units Together
Follow these steps to assure a secure, level lineup.
A. Begin all lineups leveling from highest point of
floor.
B. After the ’first’ case is level, apply industrial
grade butyl caulk on non-visible areas (at case
end). Use industrial grade silicone sealant on
visible areas (at case end).
C. Form Two (2) Caulk/Sealant Lines
and Refrigeration). See illustration at
below-right for outline of caulk/sealant lines.
D. Line up ‘second’ case bolt-hole to bolt-hole to
‘first’ case.
E. Using SCC-supplied bolts (found in installation
packet), insert bolts in bolt hole locations (shown
at right). You may need to remove decking to
access lower bolt holes.
F. Caution! Front of cases MUST be fl ush with
each other! Also, after leveling, all cases to be
at same height.
G. Using SCC-supplied nuts & bolts, lightly tighten
each of the 5 to 8 bolts in a cross-wise pattern.
Work your way around the pattern, tightening
more firmly at each pass. Do not
one bolt and then start on the next!
H. After the cases are bolted together, level the
‘second’ case. Repeat this process for each
case to be adjoined.
I. After all lined-up cases are level, seal all seams
with industrial grade silicone sealant.

support rails), make certain that the case is in
proper position and, if required, aligned with
adjoining case(s).
This may require the repositioning of the case you
are installing or
7. Frame Support Rails Must Be Shimmed

2. Hot Gas Evaporator System.
Hot gas serpentine coil is routed through a condensate
reservoir allowing water to be heated. This system
uses a wicking material (partially submersed) with
warm condenser air passing through it for evaporation.
Also incorporates an overflow reservoir with heating
element to ensure complete condensate removal.
