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, 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 an
immediate inspection of your concealed damage item. Crating material must be retained to show
the inspector from the truck line.
GENERAL ELECTRICAL & GROUNDING
DANGER:

INSTALLATION INSTRUCTIONS
Locating 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 are excessive air movement or air disturbances.
The case requires a minimum of 12” clearance at the rear of the unit for air discharge. Do not locate case
with back tight against the wall.
No clearance is needed on sides of the unit.
Removing Case From Shipping Skid and General Installation
CAUTION:
door frames and do not pull on end panels when removing the case
from the skid or moving the case. Case damage or glass breakage will result.
1. Remove crate top and sides and note missing or damaged items as explained in the pre-installation
procedures outlined above.
2. Move the case as near as possible to the final location and before removing it from the shipping skid.
3. Remove the (4) brackets that secure the case to the shipping skid.
4. Prepare cabinet according to instructions in this section that pertain to your model.
5. Lift the case off of skid and into required position. Only lift the case from under the rear lip and front
bottom trim channel above the base. Note: Do not push or pull on front bottom trim channel.
6. The case must be level for proper drainage of defrost condensate to the condensate evaporator. Using
the wrench provided level and square the case as needed by adjusting the leg leveler in each corner of
base. The 6’cases also have a set of leg levelers in the center. These must be adjusted so the base is flat.
7.
The leveled case must be sealed to the floor using a NSF Listed Sealant.
Do not push or pull against the top end glass, or
Cleaning
For initial setup, clean the case as outlined in the “Weekly Cleaning” section of this manual.

The self-contained models are shipped from the factory with a completely operational 404A refrigeration
system and require no modifications or adjustments upon installation. Case must be installed as per the
installation section of this manual to provide proper condensing air cooling.
Self Contained Refrigeration Operation
The unit temperature is controlled by the low pressure side of a dual high/low pressure switch. The
compressor will run until either the minimum run timer times out (approx 10 min) or the suction pressure
reaches the set cut out point at which time the compressor turns off. The compressor will remain off until
the suction pressure rises and reaches the set cut in point of the pressure switch at which time the
compressor turns on.
Note: The condenser fan runs continuously.
This unit also has a defrost timer that will shut the compressor off a set number of times per day to insure a
full defrost occurs. The compressor will remain off until the either the off time is reached or until the
temperature sensor on the coil reaches a set temperature which ever happens first.
Remote Models Use pressure gauges to set pressure control.

Remote Models
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. A thermostat senses evaporator
temperature and opens and closes the refrigerant solenoid valve. 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 temperature control may require some adjustment by
installer for proper operation of unit. This unit also has a defrost timer that will shut the refrigeration
solenoid off a set number of times per day (set at factory for 3 times per day) to insure a full defrost occurs.
The solenoid will remain off until the either the off time is reached or until the temperature sensor on the
coil reaches a set temperature which ever happens first
The condensing unit is optionally supplied from the factory for remote location installation. The
condensing unit supplied from the factory will require a high low pressure switch that 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. A drier/filter must also be installed by installer.
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 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 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.
