Floor Preparation

Be sure the floor where the case line up will be located is strong enough to support cases without 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 up is complete. If it all possible make all connections accessible from front under side of 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 used. 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 touching. Install fasteners in the order below as designated with corresponding letter in 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 14 -20 bolt and 14 -20 nut, use a 14 washer against each base support as shown in diagram.
B) Align the top front of case and fasten through hole in top support using 14 -20 bolt and 14 -20 nut, use a 14 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.

SELF-DRILLING SCREWS VALANCE JOINING STRAP SELF-DRILLING SCREWS

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 14 -20 bolt and 14 -20 nut, use a 14 washer against each top joining rail as shown in diagram.
E) Align slots in rear joining rail and join using 14 -20 bolt and 14 -20 nut, use a 14 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.

MISTER OPTION

This case may be supplied with a mister option kit. The mister rail and mister nozzles are installed in the case at the factory along with the mister inlet hose.

Assemble the controller and pressure tank in desired location as outlined in the instructions included with the mister kit and attach to the mister inlet hose.

Set the control interval cycle times between mist operation and the duration of misters on time to achieve desired mister results. It is recommended to try to have as much time between mister operation and the shortest mist on time as possible to achieve the desired results. If to much water is added to the case it could cause refrigeration coil to build ice and cause poor case performance.

The mist nozzles can be tilted in and out to desired location. It is recommended that the nozzles point to the inside of the case to prevent water mist on floor.

The nozzle spray mist pattern can also be adjusted by turning the end of each nozzle.

Pre-Service Checklist

You may avoid the cost and inconvenience of an unnecessary service call by first reviewing this checklist of frequently encountered situations that can cause unsatisfactory case performance.

TION: Before servicing case, turn off power at the main breaker of fuse box.

Case Does Not Operate

Check for disconnected power supply.

Check for tripped breaker on blown fuse.

Check that the thermostat display is on and that the green indicator light is lit.

Lights Do Not Operate

Check that light switch is on.

Check for tripped breaker or blown fuse.

Check that light housing cords are plugged in correctly to sockets in the tower

Case Temperature Too Warm

Check that the cold air inlet and outlet slots are not blocked.

Check for a blocked or dirty condenser coil.

Check for cold airflow. Lack of adequate cold airflow could indicate a defective evaporator fan or a blocked evaporator coil. Check that paper or foreign materials are not blocking evaporator. If the evaporator coil is blocked due to excessive frost, put into manual defrost. Excessive frost can buildup overtime if the case is set too cold or if there is excessive humidity in the store.

Check all the fans in the evaporator compartment and tower are running.

Case Sweating Note: Some interior sweating is normal on this case.

Check room ambient - Case is designed to operate in an environment not to exceed 75^ and 55% relative humidity.

Check all the fans in the evaporator compartment and tower are running.

Overflow of Condensate Pan

Check that drain in bottom of tub floor is not plugged.

Check that drain trap to the condensate pan is not plugged

Overflow of Optional Condensate Pump:

Check that drain in bottom of tub floor is not plugged.

Check that drain trap to the condensate pan is not plugged

Check that drain lines from pump is not plugged or pinched.

Check to see that pump float is operating correctly.

Verify that pump is plugged in and has power.

Replace pump if still not pumping condensate.

Special Service Situations

There are rare occasions when the refrigerant charge must be evacuated from a case in order to perform service work. In those situations, Federal Industries recommends that the refrigerant charge be evacuated into a recovery system to prevent the possibility of hydro-fluorocarbons (HFC's) from being released into the atmosphere.

The release of HFC's into the atmosphere is a potential source of global warming. Note the condensing unit that was supplied with this case has a receiver tank large enough to hold all the charge you may be able to pump down the system when service is required.

If moisture or liquid is observed around or under a Federal Industries case, an immediate investigation should be made by qualified personnel to determine the source of the moisture or liquid. The investigation made should determine if the case is malfunctioning or if there is a simple housekeeping problem.

Moisture or liquid around or under a case is a potential slip / fall hazard for persons walking by or working in the general area of the case. Any case malfunction or housekeeping problem that creates a slip / fall hazard around or under a case should be corrected immediately.

SALE & DISPOSAL

If you the owner sells or gives away this Federal Industries case it is the owner's responsibility to make sure that all safety labels and the Installation-Service Manual are included with it. If you need replacement labels or manuals, Federal Industries will provide them free of charge. Contact the customer service department at Federal Industries at [phone].

The customer service department at Federal Industries should be contacted at the time of sale or disposal of your case so records may be kept of its new location.

If you sell or give away your Federal Industries case, you should evacuate the refrigerant charge before shipment. Federal Industries recommends that the charge be evacuated into a recovery system to prevent the possibility of HCFC's from being released into the atmosphere.

Refer to the rating plate data attached to side of base for Maximum Fuse Size and Minimum Circuit Ampacity.

The remote models are designed to use 404A refrigerant and shipped from the factory with the evaporator coil, expansion valve, sight glass and refrigerant solenoid valve. Drier filter most be installed in field for proper operation. Electronic control runs identical to the Self Contained models except the electronic control opens and closes a refrigeration solenoid valve located on the suction line instead of turning on and off a compressor. The solenoid valve closes and shuts off the refrigeration flow to the unit and initiates a pump down cycle. This will allow the remote low pressure switch to open and shut off remote compressor.

The condensing unit and pressure controls are optionally supplied from the factory for remote location installation. The condensing unit must be mounted and wired by the installer. The high low pressure switch must be wired in series with the compressor power supply as shown in diagram below.

1. Mount condensing unit indoors as close to the remote display case as practical. The refrigeration line should be as short as possible and must not exceed 30 feet.
2. All refrigeration and/or electrical materials between the condensing unit and display case are to be supplied by installing contractor.
3. Route properly sized and designed refrigeration lines from the condensing unit to the cabinet. Horizontal suction lines should be pitched downward towards the condensing unit at least 12 " per 10' run to aid the oil drainage. A "P" trap must be installed in the suction line at the foot of every riser to insure oil return. Dry nitrogen must be used to flow through tubing while brazing refrigeration lines.
4. Suction line must be insulated the entire length with Armaflex (or equivalent). Do not run liquid line inside insulation with suction line.
5. The remote high/low-pressure control must be mounted, wired and set pressures by the installer.
6. Leak check condensing unit, cabinet, and all connecting tubing. Cabinet and condensing unit tubing should be checked to insure no leaks occurred during shipping or from rough handling.
   Make certain all refrigeration valves are opened and evacuate system to 500 microns. Charge the system with refrigerant type specified on the data plates.

Electrical Connection

DANGER: Improper or faulty hookup of electrical components in the display case can result in severe injury or death

-Only a licensed electrician must perform all case electrical connections.

-All electrical wiring hookups must be done in accordance with all applicable local, regional, or national electrical standards.

-A separate circuit for each display case is required to prevent other appliances on the same circuit from overloading the circuit and causing malfunction.

-The electrical service must be grounded upon installation.

- See the electrical data plate for display case and Condensing unit assembly for proper circuit size and wire ampacity.

There are two power sources required for this unit. The LMD merchandiser requires a 120/1/60 power supply and the condensing unit assembly requires 240/1/60 power supply. The Merchandiser unit and the condensing unit assembly do not share any wiring. The refrigeration system is operated by the use of a solenoid in the merchandiser and a pressure control located on condensing unit.

LMD Merchandising Electrical Connection: The electrical connection box is on the bottom left side of case behind the bottom Front Kick Panel. The box is accessible by removing the Front Kick Panel. (See “Panel Removal Section” of the owner’s manual for panel removal instructions). Remove electrical box cover to access electrical connection. An optional power cord may be provided.

Refrigeration Line Connections.

The remote merchandiser and the condensing unit are both pre-charged with refrigerant. Reusable quick connect couplings are provided for field installation. If top condensing unit assembly must be removed the quick connect couplings can be disconnected and reused.

After the condensing unit assembly is securely attached to the merchandiser, remove the plastic caps from the fittings and make the refrigerant line connections as described below.

Once connection is made, it is recommended to leak test the quick connect fittings using a soap solution to insure the joints are leak free. Both refrigeration service valves on the condensing unit are ‘ back seated’ when shipped and do not require adjustments in the field.

Rigid Refrigeration Line Connection

CONDENSING UNIT ASSEMBLY REFRIGERATION CONNECTION LOCAED ON BACK OF CONDENSING UNIT REFRIGERATION LINE ARE MOUNTED TO BACK OF LMD UNIT.

The Rigid refrigeration lines are factory mounted to back of LMD case. Once located in proper position the couplings between top condensing assembly and LMD unit can be made as described in in Line-Set Field Installation Instruction section below.

CONDENSING UNIT ASSEMBLY CONDENSER BASE PLATE INSULATION WRAP REFRIGERATION LINES MOUNTING BRACKETS

-Cut the wire ties holding the wrapped flexible refrigeration lines to the back of LMD display case.

-Rout the lines as needed over the top of the LMD case to the front of the condensing unit where the refrigeration connections are located. This routing will vary depending on application. Use caution to route lines so that they do not pinch or over bend.

-Connect couplings between top condensing assembly and LMD unit can be made as described in Line-Set Field Installation Instruction section below.

-IMPORTANT: The refrigeration lines must be attached to the support plate using the mounting brackets. Insulation wrap must be in the location of mounting bracket to prevent damaging lines.

-There also mounting brackets located on back of condensing unit. These may or may not be used depending on the particular routing of the lines. It is just important that the lines are secured in such a manner to prevent damage to lines if the LMD unit is moved around. Any extra Refrigeration line should be left loose behind the LMD unit to allow LMD to be moved around without pulling on line set.

Line-Set Field Installation Instructions

Step 1

Apply refrigerant oil to the entire surface of diaphragm, o-ring, and threaded area of male coupling assembly. The amount of lubricant used must cover all designated surfaces sufficiently. Ideal application is a small applicator brush saturated with lubricant and applied liberally. An alternate lubricant for this application is a refrigerant compatible silicone grease product like Dow Corning DC200/60,000 cst.

Step 2

Ensure that the coupling halves are held in proper alignment with each other prior to starting the threads of the female coupling nut onto the male half. The coupling end faces should be parallel with each other and visually in line with each other, this allows the female coupling nut to be easily threaded on by hand for the initial 2-3 rotation of the union nut. These initial rotations will bring the diaphragm in contact and a sharp increase in torque will be felt when they come into contact.

If the nut will not start by hand, adjust the position of the line set to ensure proper coupling alignment and eliminate/minimize all side-load force on the coupling during assembly.

Step 3

Using appropriate size wrenches, reference table below for the female coupling body and female union nut, tighten the female union nut while preventing rotation of the female body with respect to the male half. The nut should be tightened until a definite increase in resistance, metal to metal contact occurs, is felt (at this point, the nut will have covered most of the threads on the male body). It is important to ensure the male and female coupling bodies DO NOT ROTATE during any portion of the wrench installation.

Step 4

Using a permanent marker or scribe, mark a line lengthwise from the female coupling union nut to either the bulkhead or female coupling body. Then tighten an additional one (1) wrench flat (60°); refer to the marking on the union nut to confirm the rotation has occurred. This final rotation is necessary to ensure the formation of the leak-proof seal, between the male and female couplings.

Step 5

Repeat step 1 through 4 for all connections.

Refrigeration Line Disconnections.

Reusable quick connect couplings are provided for field installation. If top condensing unit assembly must be removed the quick connect couplings can be disconnected and reused. Before disconnecting refrigeration couplings:

-Disconnect power to merchandiser unit. This will allow refrigeration solenoid to close.
-Allow condensing unit to run until the condensing unit shuts off. This allows most of the refrigerant to be pumped into receiver tank.
-Disconnect power to top condensing unit.

Drain Line

Connect the clear plastic drain line to the barbed fitting on the top of the condensate evaporator screen. Use the hose clamp provided to secure to fitting.

-Make an inspection on the condensate drain system at this time

-Check that the white PVC drain trap assembly is securely connected to the drain at the bottom of the case and has not come loose in shipment

-Check that the white PVC drain trap assembly is properly positioned in the inlet of the condensate pump.

-Check that the clear PVC tubing is connected to the pump and to the electric condensate evaporator barb fitting
