INSTALLATION PROCEDURES
WARNING
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.
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 tags.
Pre-Installation Check List
WARNING
These cases are very heavy and require
two or more people to unload, move,
position and/or install them. Improper
handling of these cases could result in
personal injury.
NOTE:
Cases with legs or pedestals are shipped
to stores on skids under the base frame.
Cases should be unloaded and moved by
one of the conventional methods
All cases containing glass MUST be stored
and installed on level surfaces to avoid
possible product damage and/or glass
breakage.
1. Check for hidden damage while
unloading and unpacking of the case.
2. Check the “shipped loose” parts for any
items; such as legs, pedestals, shelves,
nuts and bolts, caulking, access doors,
etc.
3. Check the equipment - remove the screws
used to hold down the deck pans during
shipping. Remove the pans and check
the following, if applicable:
4. Remove all packing material.
5. Check all flare nut connections for
tightness.
6. Check all fan bracket bolts for tightness.
7. Check all electrical plug-in connections
for positive seal.
8. Make sure the expansion valve feeler bulb
is securely attached to the suction line.
9. All field wiring and plumbing MUST
conform to national, state, and local
codes.
10. Do not remove plugs (from flare nuts) or
caps (from threaded connections) until
the unit is ready for final hook-up. All
coils are pressurized and have a Schrader
Valve access fitting. If pressure has been
lost, check for leaks.

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.
WARNING
• These cases are very heavy and require
two or more people to move, position
and/or install them.
• Do not walk on the tops of these cases.
Tops of cases are not designed to
support the weight of a human being.
Improper handling of these cases could
result in personal injury.
1. Snap chalk lines where the front and rear of
the case legs or pedestals are to be located
for the entire line-up.
NOTE
Front and rear edges of legs or pedestals
should always be used to line-up cases.
Cases with legs have built-in leveling
adjustment capabilities. Cases with
pedestals use 6” shims to make leveling
adjustments.
2. Cases are shipped on skids. Using a
proper lifting devise, lift case off skid and
position case where it is to be installed.
While the case is properly supported,
install legs into threaded holes in base.
Make sure all legs are completely
threaded into the base to properly
secure them. Carefully lower case until
it is supported by the legs or pedestals.
Thread out bottom leg insert, up to 1 1/2”,
to level the case.
If case has pedestals, locate highest
point on chalk lines as a reference for
determining the number of shims to be
placed under case pedestals. Position
first case at the highest point on the
chalk lines and shim case pedestals as
required.
Check leveling across the top of the case
and on top of the front cladding.
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.
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!

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.
The case should be leveled across the top (1),
close to the hinge, and on the top of the front
cladding (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, adjust the legs at the case corners
or shimm the pedestals. Leg adjustment or
shimming will ensure proper operation and
alignment of the lift glass.
The handle on the lift glass must rest evenly
on the front cladding. 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.
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. Push cases tightly together making sure
the pull-ups are aligned.
5. Adjust legs or add shims under the end
pedestals, as required. Check leveling at
top of the case and on top of the front
cladding.
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.
6. Position pull-up bolts and mounting hardware at pull-up locations (A and B). 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 B. Do not overtighten.

Rear Rail Cover & Close-off Installation
(Cases with Pipe Legs)
Position rear rail cover (1) over rear raceway
opening and secure with screws in every
hole.
Bottom and End Close-off Installation
Kickplate, optional rear bottom and end
close-offs have spring clips on their back
sides that secure to the pipe legs.
NOTE
Optional rear bottom close-offs do not
require joint trim.
1. Before installing kickplates on a multiple
case lineup, snap a joint trim (2) over
the top and bottom of one of each
kickplate (3).
2. Lineup each kickplate (3) and/or optional
rear bottom close-off (4) and push to
secure the spring clips to the legs (5).
3. Slide joint rrims (2) over the case-to-case
joints.
4. Position end close-offs (6) over the end
of the kickplate (3) and/or optional rear
bottom close-off (4) and push until the
spring clips secure to the legs.
Trim Installation
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), front kickplate joint trim (4), front
lower cladding joint trim (5) and front upper
cladding joint trim (6), color band backer (7),
glass stop joint trim (8) and horizontal joint
trim (9).
Horizontal joint trim covers gaps between the
cases. The trim is glued onto the shipping
cardboard. If trim has a notched side, apply
trim with notched side towards front of case,
after running beads of caulking on the edges
of the cases. Sheet metal screws 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.
The patch end must seal tightly against the
lift glass wiper to ensure proper operating
temperatures.

Optional 2” Bumper Installation
1. Install bumper retaining track on cladding
with screws, if required, using same
alignment as old bumper track.
2. Cut vinyl bumper slightly longer than
overall length of case line-up. Starting
at either end of the case, snap end of
bumper onto the bumper retainer track.
3. Curve the bumper back as illustrated.
This will open the bumper and allow it
to snap onto the retainer track. Working
in one direction, “roll” the bumper onto
the retainer track. Just before reaching
the opposite end, final cut the bumper
(approx. 1/8”) longer than the bumper
retainer. The additional 1/8” length will
allow for normal shrinkage from case
cooling.
NOTE
Bumper unevenness may be remedied by
striking with a mallet and straight board
along the length of the installation.
See “General (UL/NSF) I&S Manual” for
Plumbing Procedures.
Refrigeration Procedures
Refrigeration system and superheat
instructions can be found in the “General
(UL/NSF) 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 TLM, TLF and TLD cases use an
electronic thermostat for improved
temperature control.

Cleaning Instructions
WARNING
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.
• Liquid chlorine bleach is corrosive to metals. The use of bleach or products containing
bleach will damage metal surfaces and void the case warranty.
• Sanitize the case with Quaternary Ammonium Solutions (ex: KAYQUAT II, J-512 Sanitizer,
SANIQUAT 512, tec...) approved per 21CFR 178.1010, followed by adequate draining and
air drying. These solutions may be obtained from Kay Chemical Co., Johnson Wax
Professional, Coastwide Laboratories, etc....
• 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.

Lift-Glass Gas Piston Replacement
WARNING
The TL series cases rely upon gas pistons
to assist lifting the glass and holding it in
the raised position. The glass is heavy and
difficult for one person to lift alone while
replacing a gas piston. Use an assistant
to prevent possible glass breakage and/or
personal injury.
Since gas pistons are very powerful when
in compressed state, follow these cautions
during replacement:
• Do not attempt to perform any work on
case while piston is in compressed state.
• Raise glass to full UP position before
beginning any work involving gas
pistons.
• Do not attempt to alter a gas piston in
any way.
• Do not expose a gas piston to excessive
heat.
• Dispose of gas piston as soon as
possible after removal.
Each lift glass panel uses four gas pistons and
two hinges to support it. Example: 8’case has
2 lift glass panels with 4 hinges and 8 gas
pistons.
1. Have an assitant lift and hold the glass in
the full UP position. Note position and
relationship of all glass lift components.
April, 2007

edge channel before removing.
3. Loosen set screws in back of top edge
channel.
4. Using a flathead screwdriver, push
down aluminum wedge inside top edge
channel, until it rests in bottom of the
channel. After wedge has been released
from glass, remove the old glass from
the top edge channel.
5. Position the top edge channel on the new
glass panel in same position as removed.
NOTE
Glass must be fully inserted into top edge
channel before tightening.
6. After glass is positioned in the top edge
channel, tighten each set screw until
glass is held into place by the aluminum
wedge. Do not overtighten.
6. With aid of assistants, lift and tentatively
position new glass assembly in the hinge
slots. Tighten the hinge set screws. Do
not overtighten.
7. Slowly lower glass to check position. If
adjustment is necessary, raise glass and
have assistants hold both ends. Loosen
the hinge set screws, adjust the glass
assembly position and retighten set
screws to secure top edge channel in
hinge slot. Do not overtighten.
