Single Case Installation

Leveling The Case

It is important that the cases are level. This will allow for proper drainage of condensate water from evaporator coil. Once the case is rolled to final location the case must be level for proper drainage of defrost water to the condensate pump. A wrench is included to aid in adjusting leg levelers

Check the level of the case along front of acrylic air deflector. Adjust the (4) outside leg levelers as needed to level the case in each direction. The LMD72 &LMD96 have (2) center leg levelers adjust these so that the center of base floor is flat.

NOTE: If necessary use a wood or plastic shim under each leg leveler to avoid scratching the tile floor.

Sealing Unit to The Floor

After the unit is positioned and the leg levelers are turned out, the unit needs to be sealed to the

loor for NSF approved installation.

wo Cases Connected to Single Remote Condenser

If (2) cases are ordered from factory to run on a single condensing unit, there is only one control that will operate both units.

The cases are prewired to connect both refrigeration solenoids together. These Wires are hanging out from joining side of each case near the top front behind canopy.

Once all prep work is complete and both cases are ready to be joined, connect the wires from each case together. Connect the yellow wire from case 1 to yellow wire to from case 2 and connect the white wire from case 1 to white wire from case 2.

Once connected join cases as described below. Be careful not to pinch the wires between cases.

CAUTION: The refrigeration solenoid on the case that does not have a control is

cases disconnect power from both cases to prevent electrical shock.

DANGER

HIGH VOLTAGE. Turn power off before servicing. May have more than one disconnect switch.

"IMPORTANT" BEFORE INSTALLING CASES TOGETHER CONNECT YELLOW WIRE FROM CASE 1 TO YELLOW WIRE FROM CASE 2. CONNECT WHITE WIRE FROM CASE 1 TO WHITE WIRE FROM CASE 2. WHEN PLACING CASES TOGETHER DO NOT PINCH WIRES BETWEEN CASES.

Floor Preparation

Be sure the floor where the case line up will be located is strong enough to support cases w

ithout sagging.

It is important that the cases are level. This will allow for proper drainage of condensate water from evaporator coil and allow for proper alignment of cases. Most floors are not level and the high and low spots in location of cases must be determined. Place a chalk line in the desired position of where the back of the cases will be located. If the back of the cases are to be along a wall there should be at least 6” clearance between wall and the back of the cases.

Measure 33.25” from this chalk line to where the front of cases will be. This line is where the front base rail meets the floor not the actual front of the case.

Mark the location along these lines that the outside edges of case will be. The cases without end panels will be 48”,72”, or 96” depending on cases ordered. Add additional 1” to case end that has an end panel.

Use a transit or line level to determine the highest point along chalk line.

Joining and Leveling Line Up

If case line up is along a wall it will make it difficult to gain access to back of case once line

p is complete. If it all possible make all connections accessible from front under side of

u cases, but if necessary make any required connections at back of case as you install the cases.

-There are factory installed gaskets located on each end of all adjoining cases. Inspect all gaskets to be sure they are properly located and not damaged.

-Remove the front kick plates from all cases as described Panel Removal section of this manual.

-Remove all Top Air Diffuser from all cases from upper air duct track. Loosen thumb screws on Retainers located behind air diffuser. Retainer will drop down allowing diffuser to be pulled out of case.

-The required fasteners to join cases are installed at the factory in the location they will be u

sed. These fasteners are on the left side of each case. As each case is installed remove these

fasteners from the case and reuse them.

-Determining highest point as described in Floor Preparation above. Install the case that will be located over the highest point first. Once the first case is rolled to final location the case must be level for proper drainage of defrost water to the condensate pump. A wrench is included to aid in adjusting leg levelers Check the level of the case along the ledge in front of acrylic air deflector. Adjust the (4) outside leg levelers as needed to level the case in each direction. The LMD72 &LMD96 have (2) center leg levelers adjust these so that the center of base floor is flat. If necessary use a wood or plastic shim under each leg leveler to avoid scratching the tile floor

-Place the next adjoining case into line up. Level case until case end profiles are aligned and ouching. Install fasteners in the order below as designated with corresponding letter in

t detailed diagram. As cases are joined additional leg leveler adjustments may be necessary.

A) Align the front of the base rail and fasten through hole in base rail using ¼-20 bolt and ¼-20

nut, use a ¼ washer against each base support as shown in diagram.

B) Align the top front of case and fasten through hole in top support using ¼-20 bolt and ¼-20

nut, use a ¼ washer against each top support as shown in diagram. If necessary the top valance can be adjusted to provide better alignment. Loosen the fasteners along the top of the valance located on top of case and adjust as needed. If a perfect alignment cannot be achieved Valance Joining strap can be used only if needed. Place strap over seam and attach with self-drilling screws provided.

C) Align the holes in the air deflector supports and join with 10-32 screw and 10/32 acorn nut. D) Align slots in top joining rail and join using ¼-20 bolt and ¼-20 nut, use a ¼ washer against

each top joining rail as shown in diagram.

E) Align slots in rear joining rail and join using ¼-20 bolt and ¼-20 nut, use a ¼ washer against

each rear joining rail as shown in diagram. Alternate rear attachment point shown in diagram is used if it is not possible to get to back of case. Using this attachment point requires removing all shelving and slotted back panel from both cases to gain access. See appropriate section of this manual for shelf and slotted back panel removal.

Repeat for all additional cases in line up. Once all cases are attached continue with electrical, refrigeration and drain connections as described in appropriate section of this manual. Reinstall Kick Panels and air diffusers as described in appropriate section of this manual.
