Location
Killion refrigerators are Type 1 Open Display Refrigerators and designed to operate in air-conditioned stores where temperature
and relative humidity are maintained at or below 75°F dry bulb temperature and 55% relative humidity. Avoid locations where the
refrigerator is exposed to heat sources such as the sun’s rays or hot tables as these external heat sources can affect the
refrigerator’s efficiency.
Do not enclose refrigerated display cases with walls. There should be ample space on each side of the condensing unit to facilitate
free airflow. Closing off either side by any means will cause the refrigerator undue strain, and could damage the compressor.
Air drafts will affect a refrigerator’s temperature holding capability. Be certain there is no air-conditioning or heating vents
discharging air into the display case area. Overhead fans, swamp coolers, or anything that creates a draft will disrupt the air curtain
and adversely affect the refrigerator. An open door will sometimes create an air movement that will sweep the refrigerated air out
of the merchandising area.
INSTALLATION
Read the entire INSTALLATION SECTION before placing the unit
in its final location.

For self contained refrigerators with the condensing units located in the bottom portion of the unit, do not locate the refrigerator
directly against a wall. There should be a minimum of four inches between the rear of the refrigerator and the wall.
Uncrating
Refrigerators are shipped on pallet skids. Since the refrigerators are easier to move when attached to pallet skids, move the
merchandiser close to its final location before removing from the pallet skid.
Check the shipment with your itemized sales order for possible shortage of materials. If a shortage exists, report immediately to
Killion. Check all air grills for obstructions. Verify nothing is blocking air grills.
Securing Merchandiser
If you case comes in multiple sections, please refer to the Joining Instructions to properly attach each section before securing to
units to the floor.
Once a Mobile unit is in its final location, the rear wheels must be locked in place. To lock the rear wheels, locate the locking knob
on the side of each wheel. Turn the locking knob clockwise until each rear wheel is locked.
Plumbing
Leveling
Refrigerated display cases must be level, otherwise internal drains will not function properly. With the assistance of a level,
adjust leveling feet and/or add shims to level the refrigerated display case. For mobile cases, shims should only be added
once casters are all locked. This is a good time to verify that all packaging material and other debris have been removed
from the refrigerator as these items could adversely affect the drainage system.
Self-Contained Models
These units come equipped with one of two condensate removal systems:
•High Volume Pump - The high volume pump system pumps water out of the case to a external drain or collection
reservoir. It requires routing a drain line from the case. A backflow prevention device comes pre-installed on the pump
line with 100’ of flexible reinforced tubing. If running a pipeline to the case the recommended size would be ½” I.D.
pipe. Any store installed pipe fittings must be connected after the backflow prevention device. Do NOT remove the
backflow prevention device.
The horizontal run must slope away from the case to prevent the backflow of water into the refrigerated
merchandiser. Recommended slope is four inches for every ten feet of run. The high volume pump can pump water up
to a maximum rise of 45 feet. Make sure that there are no sags in the length where condensate can pool, and any
bends in the run should be kept to a minimum.
•Condensate Wick – Water in the condensate pan is drawn up through the fabric wick while warm air from the
condensing unit is forced through the wick, drying it. A heating element at the bottom of the pan is used to provide
extra capacity in times of need. The heating element is limited by a timer to maintain energy consumption limits.
The wick must be secured into the pan and be sitting upright in the path of the warm air for proper operation. Do not
block air flowing through the wick. The wick should be inspected at least every three months and replaced as needed.
If a replacement wick is needed, please contact Killion’s customer service department at 1-800-421-5352 x120 or email
at [e-mail] .

Remote Models
Remote models contain condensate drain lines that must be properly routed to the store’s drainage system prior to
operation. The following must be observed when installing the drainage system:
The water seals are pre-installed to prevent warm air from leaking into the cooling system. Never install more than one
water seal in series in any one run of piping. Never downsize the diameter of pipe. Long runs of piping must be supported
in order to prevent sagging and maintain slope. Drainpipe opening at floor sink must be above flood rim. Never place piping
in contact with refrigeration lines. In some locations, it may be necessary to prevent the drain piping from freezing. While
there are suitable alternative methods for drain hook-up, the preferred method is to run each P-Trap independently to the
floor sink.
Electrical Supply
A licensed electrician must make or verify all electrical connections. All wiring must comply with applicable local and national codes.
Each refrigerator must be served with a separate overload protected circuit. It is necessary that a separate, dedicated circuit be
provided for each merchandiser to prevent the possibility of another appliance tripping the breaker and causing an interruption of
electrical service. Some cases require multiple power circuits. Each circuit must be connected to its own dedicated circuit breaker
and supplied with adequate power.
If your unit comes with a power cord, be sure that it is plugged into the proper mating electrical receptacle. Because of potential
safety hazards under certain conditions, we strongly recommend against the use of an extension cord with any refrigerated
merchandiser.
The unit must be connected to a properly sized power supply. Check for voltage specifications on the ETL label that is located in
one of the following locations:
•For cases without casters/wheels the label will be located in the upper right interior of case.
•For cases with casters/wheels, the label will be located on the lower left back of the case.
•If the merchandiser comes in multiple parts, there will be labels on each unit.
On self-contained cases, the power switch will be located on the right-side panel toward the bottom rear corner.
Lighting
For units with under the shelf lighting, each light has a plug that connects to a receptacle located on the back panel of the
refrigerator. These shelves may be removed for cleaning, with the light intact, by unplugging the light from the back panel of the
refrigerator. The lights may also be removed from their shelf clips and left inside the case while the shelf is removed.
For self-contained units with interior case lighting, the light switch will be located next to the power switch, on the right-side panel
toward the bottom rear. For units with exterior lights, the switch is located at the bottom left front.
Refrigeration System
Expansion Valves
All models operate with a thermostatic expansion valve. In self-contained units, the expansion valve is set at the factory and
should not require any further adjustment. In remote units, the expansion valve is set at the factory, but may require
adjustment in the field by the installing certified refrigeration technician. The expansion valve should only be adjusted
according to the valve manufacturer’s recommended procedure.

Self-Contained Models
Self-contained models are factory equipped with a temperature control unit and a pressure control. The temperature
control unit controls the case temperature, controls defrost times and durations, and limits the on-time of the heating
element in units equipped with a wicking condensate system. The pressure control is built into the condensing platform and
acts as a safety for the compressor for high and low pressure cut in’s and out’s.
Refrigeration controls are preprogrammed at the factory. Please note these settings are generic factory settings. It is
recommended that these settings be monitored and adjusted (if necessary) by a Qualified Refrigeration Service Technician
to accommodate each store’s unique ambient conditions and for the product being displayed.
The compressor runs until the discharge air coming off the evaporator coil reaches the thermostat cutout setting. Once the
appropriate temperature has been reached, the temperature controller will shut the unit off until the temperature has risen
a preset number of degrees.
Periodically, the refrigerator enters into a defrost cycle. Defrost cycles are time-initiated, and either temperature or time-
terminated. The evaporator fans continue to operate regardless of whether the compressor is running or not.
Remote Models
For proper operation, it is recommended that a solenoid valve be added to the liquid line and controlled via a thermostat
or another controller. Additionally, these units require connection to a defrost time clock to properly cycle defrost times.
Stocking / Product Load Limits
The cold air re-circulating system requires free airflow through all grills, including the grill at the lower front of the refrigerator.
•DO NOT place product in merchandisers until case is at proper operating temperature.
•DO NOT stock the product so tightly between shelves that the refrigerated airflow is hampered. Overstocking refrigerated
merchandisers can lead to reduced temperature holding capacity and expose the unit to undue strain.
•DO NOT stock product beyond the edges of the shelves.
•DO NOT place product beyond load limit lines.
•DO NOT stock product so tightly against back wall that airflow is restricted. There should be at least a one-inch gap
between the back of the case and product.
•DO NOT block any air grills, honeycomb air discharge areas, or any panels with slots intended for air intake or discharge.
For units with multiple levels for product display:
•DO NOT place bottom shelf lower than 8 inches above the bottom deck. This would cause an interruption of airflow.
•DO NOT leave less than a 1-1/2” gap between the top of the product on one shelf to the bottom of the price tag molding
on the above shelf.
•DO NOT place upper shelf less than 10 inches below the honeycomb discharge grill. This also would cause an interruption
of airflow

Relocating / Moving
Before moving or relocating a case that has been in use, it is important to remove all condensate water from all water dissipater
trays and evaporator pans, so that water damage does not occur. A wet/dry vacuum works well to remove water.
Be sure that all plumbing, electrical, and refrigeration connections are disconnected by qualified technicians before attempting to
relocate the case. Follow all directions in the Pre-Installation and Installation sections when placing the unit in its new location.
If moving a vertical-style case, it is recommended to resecure the case to a pallet using lag bolts before moving with a pallet jack.
Proper product rotation is necessary to prevent product loss. Move older product to
the front of the case and set the newer product in the back.
CAUTION
La rotation appropriée de produit est nécessaire pour empêcher la perte de produit.
Déplacez un produit plus ancien à l'avant du cas et placez le produit plus dans le dos.

If you feel that your refrigerated merchandiser is not operating properly, please review the following list before placing a service call:
Troubleshooting Check List
1. Is the refrigerator in a defrost cycle? Refrigerators periodically go into defrost cycles to remove ice buildup on the
evaporator coil. The display on the refrigeration controller will read dEF during this period. During a defrost cycle, the
refrigerator thermometer may read above 41°F. The thermometer provided in the refrigerator measures the air
temperature in the back of the case. This is only the air temperature; the product temperature will remain below 41°F
when the case is operating properly. Wait an hour and return to the merchandiser to recheck the temperature.
2. Do the store conditions exceed 75° F / 55% relative humidity? Killion Type 1 Refrigerated Display Cases are not
designed to operate in conditions exceeding 75° F / 55% relative humidity.
3. Has the compressor stopped running for an extended period of time? The most common cause is high pressure
triggering the high pressure safety switch. This can happen when the condensing coil, or the intake filter(s) to the
condensing coil, are dirty. Clean the condensing coil or replace any dirty intake filters. Have a qualified technician locate and
reset the high pressure safety switch and restart the case.
The second most common cause is a tripped float switch for any unit with a condensate dissipator pan. This is a possibility
when there is too much humidity in the store environment or if the wick filter is not properly installed. If the wick is
installed properly and still in good condition, Killion Industries can provide alternate settings for store level personnel or an
on-site technician.
4. Are external sources such as heaters, sunrays, drafts, hot tables, etc. introducing heat into the case? Move
these external sources away from the refrigerated merchandiser or move the merchandiser away from these external
sources.
5. Is the return air grill on the front of the bottom deck blocked with dust or product? Remove all product and
dust from the return air grill to ensure proper airflow.
6. Is there too much product loaded into the case that it is blocking the air flow from the back of the unit? The
load limits outlined in the Product Stocking / Load Limits section of this manual must be followed.
7. Is the case leaking water? Check to make sure that the condensate removal system is working properly. Make sure all
condensate lines and pans are free from debris. Make sure the condensate pump(s), if equipped, is operating properly. If
your system uses an evaporative wick, make sure it is secured and sitting upright in the condensate pan. Ensure that the
heating element in the condensate pan is operating properly and that the float switch is not stuck in the down position.

Killion Refrigerated Merchandisers require an adequate supply of free inlet air available. Please note
the location of the condensing unit, as both top and bottom mounted units are available. Additionally,
an unobstructed exhaust area for the dissipation of hot condensing unit air must be available so it
does not recycle into the inlet air.
Top mounted condensing units should not be located under a low ceiling or “boxed-in” under a
canopy or any similar construction thereby restricting or completely shutting off free air circulation.
Inadequate or improper airflow through the condenser section can result in higher operating
temperatures, excessive wear, and possible compressor failure.
Bottom mounted condensing units should not be located directly against a wall. There should be a
minimum of four inches clear between the rear of the refrigerator and the wall.
Installation made under such location conditions will constitute improper installation and unit abuse,
thereby invalidating all mechanical warranty coverage.
