PRE-INSTALLATION PROCEDURES
Inspection for Shipping Damage
You are responsible for filing all freight claims with the delivering truck line. Inspect all
cartons and crates for damage as soon as they arrive. If damage is noted to shipping crates
or cartons or if a shortage is found, note this on the bill of lading (all copies) prior to
signing.
If damage is discovered when the case is uncrated, immediately call the delivering truck line
and follow up the call with a written report indicating concealed damage to your shipment.
Ask for immediate inspection of your concealed damage item. Crating material must be
retained to show the inspector from the truck line.
INSTALLATION INSTRUCTIONS
Locating the Display Case
The case should be located where it is not subjected to the direct rays of the sun, heating
ducts, grills, radiator, or ceiling fans, nor should it be located near open doors or main door
entrances. Also, avoid locations where there is excessive air movement or air disturbances.
The condenser inlet is located at the rear of the case. Do not block this inlet and do not
locate the air inlet near a source of heat.
Removing the case from Shipping Skid
Move the case as near as possible to the final location before removing it from the shipping
skid.
Remove the four (4) bolts that secure the case to the skid. Do not remove the shipping
brackets from the case. The brackets are intended to be used as hand grips for locating the
case.
Remove the brackets when the case is in the final location

Series ’90 Refrigerated Bakery Page 7
Removing Packaging Material
Remove the brackets that held the case to the shipping skid.
Remove the plastic ties that hold the wire shelves and shelf brackets in place.
Remove the shipping tape that secures the doors and lift-up glass. If it is necessary to
remove tape residue from plastic materials, use cleaning compounds recommended in the
cleaning section of this manual.
Leveling the Case
The case must be level for proper drainage of defrost condensate to the condensate
evaporator.
Four (4) leg levelers are provided for leveling the case. The leg levelers can be turn in and
the case can be placed with the base frame on the floor.
The leveled case must be sealed to the floor using and NSF listed Sealant.

Refrigeration Installation
Self-Contained Models
The self-contained models are shipped from the factory with a completely operational
refrigeration system and require no modifications or adjustments of the system upon
installation.
Remote Models (Obsolete as of 1/1/2012)
The remote models are designed to use 134A refrigerant and shipped from the factory with
the evaporator coil, expansion valve, refrigerant solenoid valve, and thermostat. The
thermostat senses interior case temperature and opens and closes the refrigerant solenoid
valve as needed to maintain proper case temperatures. The condensing unit is optionally
supplied from the factory for remote location installation.
A. Mount condensing unit indoors as close to the remote display as practical. The
refrigeration line should be as short as possible.
B. All refrigeration and/or electrical materials between the condensing unit and display
case are to be supplied by installing contractor.
C. 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 and least ½” 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 should be used to
flow through tubing while brazing refrigeration lines.
D. Suction line must be insulated the entire length with Armaflex (or equivalent). Do not
run liquid line inside insulation with suction line.
E. The filter drier, sight glass, and low-pressure control are not furnished with remote
display case models. The recommended low pressure setting for R134A refrigerant is
32# cut in and 0# cut-out.
F. 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.

DANGER: Electric shock hazard. Do not operate unit with
panels removed.
Grill Removal
The front of the case has a removable base panel to access the anti-fogging fans and the
front leg levelers from inside of the case. Normally it is not necessary to remove the panel to
install the case. This panel must be in place for proper operation of the case.
There are two (2) removable panels on the back of the case. The left side panel allows
access to the light ballasts, the pullout condensing unit, and the field wiring connection box.
Remove this panel to make field wiring connections.
The right side panels has the thermometer, power switch, light switch, and thermostat
mounted to it. Removing this panel allows access to the terminal board, branch circuit fuse,
condensate evaporator, and compressor service ports. Normally it is not necessary to
remove this panel to install the case.
Condensate Evaporator
This case is furnished with an electric condensate evaporator. Plumbing connections are
not required.
The condensate evaporator is located behind the control panel box and is accessible from
the rear of the case.
Lights
Make certain that the light cord plugs are completely inserted into the sockets or arcing
may result causing damage to the plugs and sockets.
The ballasts used on this case allow removal of one or more shelf lights without affecting the
remaining lights.
Shelving
Remove both rear doors from the track by lifting them upward until the bottom edge clears
the lower door track and then outward.
Lift up the front glass to the fully open position.
Put the shelf support assembly in the desired shelf standard slots.
Plug the shelf light cords in the appropriate light socket. Make certain that the light cords
are completely inserted into the sockets or arcing may result causing damage to the plugs
and sockets.

Series ’90 Refrigerated Bakery Page 10
Put the wire shelves on the rear shelf support assembly as shown. Push the bar on the
bottom of the wire shelf into the shelf retainer clip on the shelf support assembly. If the
shelf is not in the proper position, it may disrupt the air flow in the case and cause product
loss.
Close the front glass and reinstall both rear doors.
Optional Glass Shelves
Put the glass shelves on the rear shelf support and shelf light housing as shown. The shelf
retainer should sit over the rear shelf support. If the shelf is not in the proper position, it
may disrupt the air flow in the case and could cause product loss.
Reinstall both rear doors.
Cleaning
For initial set up, clean the case as outlined in the weekly cleaning section.
