2. Electrical connections are made through the
power supply box of each case, which can be
accessed by removing the back panel above the
toe kick. The power supply is located in the
raceway as shown to the right. Voltage requirements and component amperes can be found in
the electrical section of this manual, but always
check the data tag located on the exterior of the
case. Case must be grounded.
3. Refrigeration connections will be made through
the refrigeration stub up located on the
customer left side of the case (see mechanical
view). See refrigeration information section for
caseloads and recommended settings.
Refrigeration lines may be headed together for
all cases in a lineup, if desired, by lines through
the access area under the case. Seal all
access holes with a good grade silicon or foam
tape to prevent recirculation. All lines must be
correctly sized.
For proper refrigeration performance, PRODUCT
MUST NOT BE PLACED IN A POSITION WHERE
IT MAYAFFECT THE AIR CURTAIN. Air discharge
and return air vents must remain unobstructed.
Humidifier System -
This optional feature is installed at the factory.
Initial hook-up is as follows:
1. Read installation/service guide, which accompanies unit.
2. If connecting a lineup, which shares a common
control system, connect companion case dis
charge lines.
3. For all cases, connect water supply.
NOTE: It is recommended that a pre-filter be
added to the water supply.
4. Check for leaks.
Adjust water pressure as needed. See manufacturers installation guide for further information.
Glass Adjustment
Lift Glass is installed at the factory with the case
perfectly level, if adjustments need to be made to
align the glass first check to insure the case was
properly leveled during installation.
NOTE: This is a 2-person operation. One person
must hold the glass at all times.
1. Lift the glass to its highest position as shown in
drawing to the right.
2. Loosen allen screws. (See profile next page.)
3. Starting at the right side, tap the wedge with a
#2 standard screwdriver. Repeat procedure on
the left side. Continue working right to left until
the wedge recesses into the aluminum
extrusion.
EXTREME CARE MUST BE TAKEN NOT TO
TAP THE WEDGE TOO HARD.
4. Slide the glass right or left as needed.
5. Tighten the right allen screw while holding the
left side of the glass firmly. Be careful to keep
the glass level.
6. Tighten the remaining allen screws.
7. Lower glass into position. Repeat as necessary
until glass is completely level.

Refrigeration Information
Case Operation
Refrigeration
The refrigeration in this case is thermostatically
controlled. The case refrigerates until the cut out
point on the thermostat is reached. The thermostat
opens, cutting power to the liquid line solenoid.
The compressor continues to run, the system
pumps down causing the pressure switch to open,
cutting power to the compressor. Note: Some
cases may be ordered with EPR valves to control
case temperature. For proper refrigeration performance, PRODUCT MUST NOT BE PLACE WHERE
IT WILL AFFECT THE AIR CURTAIN.
Defrost
This case is equipped with an OFF CYCLE defrost
system. The timer cuts the power to the liquid solenoid. The unit stays in off cycle defrost until the
defrost timer re-energizes the liquid solenoid.
NOTE: The evaporator fan runs continuously.
