INSTALLATION PROCEDURES

W AR NIIN G

The raised front glass projects in front of the case and could cause personal injury to workers, operators and/or customers.

• Do not remove orange warning tags from front edge of lift glass.

• Do not leave lift glass raised and unattended.

• Know where the front edge of the raised glass is when working near it.

Tyler Refrigeration

Carpentry Procedures

Case Line-Up

Before starting the case line-up, review the store layout floorplans and survey the areas where case line-ups are going to be installed.

W AR NIIN G

These cases are very heavy and require two or more people to move and/or position them. Improper handling of these cases could result in personal injury.

This case is designed so the front glass can be raised for cleaning and merchandising only. It is recommended that any cleaning or merchandising be done when the store is closed.

If this is not possible, it should be done at a time when customer traffic is low.

The raised glass should not be left unattended and should be lowered whenever leaving the case.

The glass front is marked with orange warning tags to make it noticeable when in the raised position. Do not remove the orange warning

tags.

1. Snap chalk lines where the front and rear base rails of the case are to be located for the entire line-up.

NOTE

Front and rear edges of base rails should always be used to line-up cases. 6” shims allow adjoining ends of cases to be shimmed together.

2. Locate highest point on chalk lines as a reference for determining the number of shims to be placed under the case base rails. Position first case at highest point on the chalk lines and shim case supports as required. Check leveling across the top of the case and on top of the color band.

CAUTION

If the base of this case is not sitting evenly on the floor, the case could warp when loaded and possibly break the lift glass.

Page 6 October, 1996

Installation & Service Manual

NOTE

A foam gasket is factory installed on one end of the case. This gasket fits into a groove on the adjoining case when cases are pulled together. Do not depend on the foam gasket alone to make a good seal!

LLM, LLF, LLD

CAUTION

Do not drill or use other holes through the case end for pull-ups. This may deform the case end and could cause joint leaks and/or poor refrigeration.

3. Apply two heavy beads of caulking compound from the Filler Kit to the end of case at dotted (. . .) and dashed (- - -) lines. Proper caulking provides good case refrigeration and sanitation.

4. Remove shipping tape from color band backer and bumper backer.

5. Push cases tightly together making sure the pull-ups are aligned.

6. Add shims (1), as required, under the adjoining case base rails (2). Check leveling at top of the case (3) and on top of the color band (4).

7. Position pull-up bolts and mounting hardware (5) at pull-up locations (A, B, C and

D). Do not tighten any pull-up hardware until all of it has been installed. Tighten all pull-up hardware equally starting at point A and finishing at point D. Do not

overtighten.

Lift Front Glass Leveling Instructions

Accurate leveling is critical for the proper operation of the lift glass on this case.

In some instances, setting the case on an apparently level floor can cause the lift glass to fit improperly. If there is any twist in the body, it could cause the lift glass not to fit or work properly.

The emphasis when leveling this case must be on making sure the lift glass works and seals properly.

October, 1996 Page 7

LLM, LLF, LLD Tyler Refrigeration

2. Remove all hinge stops (1) from the shanks of the hex head bolts (2).

Trim Installation

The case should be leveled across the top

(1), close to the hinge, and on the color band

(2). A 4 foot level is recommended, and both

places should be level! This will enable the lift glass to fit and work properly.

If the lift glass still doesn’t close or line-up properly, add shims to case corners.

Shimming will ensure proper operation and alignment of the lift glass.

The handle on the lift glass must rest evenly on the color band. Proper lift glass sealing is essential for good product refrigeration.

NOTE

• Do not anchor the base to the floor or enclose the case until the lift glass is fitting properly and working correctly.

• Make sure all lift glass hinge stops have been removed to ensure proper operation.

To remove lift glass hinge stops:

1. Open rear of fixture and locate the hinge assemblies (2 on 4’ glass and 3 on 6’ glass).

Page 8

The joint trim and mounting hardware are shipped loose. Trim includes top joint trim

(1), rear upper joint trim (2), rear lower joint trim (3), rear base joint trim (4) and horizontal joint trim (5).

Horizontal joint trim covers gaps between the cases. The trim is glued onto the shipping cardboard. It is applied after running beads of caulking on the edges of the cases. Sheet metal screws or pop-rivets can be used for additional securing.

Patch end trim is shipped factory installed. If field installation is required, be sure the patch end is pulled up enough to fit snuggly against the sealing tubing on the inside of the case.

October, 1996

Installation & Service Manual

The patch end must seal tightly against the lift glass wiper to ensure proper operating temperatures.

See “General I&S Manual” for bumper and color band installation and alignment.

Refrigeration Procedures

Refrigeration system and superheat instructions can be found in the “General

I&S Manual”. Service case temperature control information is listed below.

Temperature Control

The temperature of each case is controlled with a thermostat and suction line solenoid.

One thermostat and one solenoid are required for up to three cases.

The LLM and LLF cases use a gravity coil with an electronic thermostat for improved temperature control. LLD case uses a conventional mechanical thermostat.

Typical Service Case with Gravity Coil

LLM, LLF, LLD

Typical Service Case with Blower Coil

THERMOSTAT BULB MOUNTED

UNDERNEATH COIL

October, 1996

In addition to the thermostat and suction solenoid, a suction stop EPR valve is required in the suction line. The EPR valve acts as a low pressure limit to aid in the overall tempetrature control.

Page 9

LLM, LLF, LLD

Setting Electronic Thermostat (LLM/LLF)

1. Remove the four screws and cover from the electronic thermostat.

2. Set the heating/cooling jumper blocks to the “COOL” position.

3. Adjust the differential potentiometer marked

“DIFF” to 10°F (LLM) or 1°F (LLF).

4. Position the setpoint dial, on the front cover, to 29°F (LLM) or 34°F (LLF).

5. Check the temperature cycles by suspending a thermometer in the same general area as the thermostat probe. The temperature should cycle between 19°F and 29°F

(LLM) or 33°F and 34°F (LLF).

6. Replace the cover and secure with four screws.

With the cooling mode selected, the differential is below the setpoint. The relay will energize and the LED indicator will illuminate when the temperature reaches the setpoint (29°F or

34°F). When the temperature drops to the setpoint (29°F or 34°F) minus the differential setting (10° or 1°F), the relay and LED indicator will de-energize and refrigeration will stop.

Start the refrigeration system (note that the

LED indicator is illuminated) and allow the case to cool. This allows the thermostat to cycle the suction solenoid valve from open to close.

The settings above are specific to TYLER service cases with gravity coils only. Other applications will require different set points

CLEANING INSTRUCTIONS

W AR NIIN G

TYLER Refrigeration does not recommend the use of high pressure cleaning equipment on service style cases!! The sealing of front glass and end joints is critical in these cases and high pressure cleaners can penetrate and/or damage these seals.

Damaged seals allow water leaks and/or air leaks that can cause poor case refrigeration.

CAUTION

• When cleaning this case, try not to introduce water into the case faster than it can be carried away by the waste outlet.

• Always use a soft cloth or sponge with mild detergent and water to clean the front glass. Never use abrasives or scouring pads to clean glass. They can scratch and/or damage the glass.

See “General I&S Manual” for case cleaning instructions. Stainless steel cleaning is covered in the following chart.
