Important Information
The AB Meat merchandisers are easy to work, attractive
merchandising display cases capable of maintaining superb
product quality, with the installation of the proper
controlling devices. These should be set according to the
manufacturer’s specifications and combined with a properly
maintained humidity system. Incorrect settings and failure
to maintain the humidity system will result in short product
life from dehydration, shrinkage and discoloration. Below
are a few guidelines to ensure optimum performance and
product life.
•Review the Case Specification in this book to verify
thermostat setting. Do not set temperature too
cold, as this causes product dehydration.
•Temperatures should be achieved by a t-stat and
suction solenoid at each case. Do not use EPR valves,
liquid line solenoids or electronic control devices of
any kind. These controls allow temperature
swings causing product dehydration and
excessive energy consumption.
• Defrost cycles should be set according to the Case
Specifications in this book
•Clean humidity system a minimum of every 90 days
for proper system operation.
•Work and rotate product – not to exceed a four (4)
hour period.
•At night turn off case lights and cover product with
moistened cheesecloth or fabric towels.
•Keep meat holding box at 32°.
•Keep meat prep room refrigerated at 55°.
• Meat bloom box (if applicable) should be at 36°.
• Meat must enter the case at 40° or below. Product
deterioration is very rapid above 40
°.
• Maintain sanitary conditions throughout the meat
holding, prep and working areas.
• Do not display product directly within the air
discharge.
• Turn and rotate the meat. The blood which
gives the pink color works down in time
which causes surface discoloration and
dehydration. When turned before this
condition occurs the other side is kept in
good color (bloom) condition. The meat can
even be turned (3) three and (4) four times.
• It is not required at night to remove the
product from the case. Turn the lights off at
night and cover the product. We recommend
you use a moistened cheesecloth or towels.
This helps slow down the product
dehydration process by taking the moisture
from the cloth and not from the product. This
is an old method that meat shops have used
for many years. It works and helps to gain
extended product life.
• Cold coils remove heat and moisture from
the case and deposit it as frost on the coil.
Thus a defrost is required to remove this
frost. Our humidity system adds moisture to
the case and helps slow down the dehydration
process. The only other moisture in the case
is in the product. A single level of meat in a
case will dry out much faster than a fully
loaded case with three to four levels of meat.
• The colder the case, the faster the product
loses its moisture and shelf life. It is very
important to maintain a constant even
product temperature (see Case
Specifications).

LOCATION
The refrigerated merchandisers have been designed for
use only in air conditioned stores where temperature and
humidity are maintained at or below 75°F and 55% rela-
tive humidity. DO NOT allow air conditioning, electric fans,
ovens, open doors or windows (etc.) to create air currents around the merchandiser, as this will impair its correct operation.
Product temperature should always be maintained at a
constant and proper temperature. This means that from
the time the product is received, through storage, preparation and display, the temperature of the product must
be controlled to maximize life of the product.

UNCRATING THE STAND
Place the fixture as close to its permanent position as
possible. Remove the top of the crate. Detach the walls
from each other and remove from the skid. Unbolt the
case from the skid. The fixture can now be lifted off the
crate skid. Lift only at base of stand!
EXTERIOR LOADING
These models have not been structurally designed to sup-
port excessive external loading. Do not walk on their
tops; This could cause serious personal injury and damage to the fixture.
DO NOT SEAL JOINT T RIM T O FLOOR!
WASTE OUTLET AND P-TRAP
The waste outlet is located off the center of the case on
one side allowing drip piping to be run lengthwise under
the fixture.
A P-trap must be installed to prevent air leakage and insect entrance into the fixture. (P-traps are not supplied
with these cases.)
NOTE: PVC-DWV solvent cement is recommended.
Follow the manufacturer’s instructions.
INSTALLING CONDENSATE DRAIN
Poorly or improperly installed condensate drains can seriously interfere with the operation of this refrigerator,
and result in costly maintenance and product losses. Please
follow the recommendations listed below when installing
condensate drains to insure a proper installation:
1. Never use pipe for condensate drains smaller than
the nominal diameter of the pipe or P-trap supplied
with the case.
2. When connecting condensate drains, the P-trap
must be used as part of the condensate drain to
prevent air leakage or insect entrance. Store plumbing system floor drains should be at least 14" off the
center of the case to allow use of the P-trap pipe
section. Never use two water seals in series in any
one line. Double P-traps in series will cause a lock
and prevent draining.
3. Always provide as much down hill slope (“fall”) as
possible; 1/8" per foot is the preferred minimum.
PVC pipe, when used, must be supported to maintain the 1/8" pitch and to prevent warping.
4. Avoid long runs of condensate drains. Long runs
make it impossible to provide the “fall” necessary for
good drainage.
5. Provide a suitable air break between the flood rim of
the floor drain and outlet of condensate drain. 1" is
ideal.
6. Prevent condensate drains from freezing:
a. Do not install condensate drains in contact with
non-insulated suction lines. Suction lines should be
insulated with a nonabsorbent insulation material
such as Armstrong’s Armaflex.
b. Where condensate drains are located in dead air
spaces (between refrigerators or between a
refrigerator and a wall), provide means to prevent
freezing. The water seal should be insulated to
prevent condensation.

Fractal Humidity System
GENERAL INFORMATION
The Service Case Humidification system is an automatic
moisture maintenance system designed to raise humidity
levels in any new or existing service case counter or
refrigerated floral display. It delivers a damp fog into the
service case or floral display at selected intervals by using
a combination of air and water.
The system consists of a humidification nozzle assembly,
water filtration/regulator unit, remote timer, and air
compressor unit (see attached diagram).
PLEASE READ ALL INSTRUCTIONS BEFORE
BEGINNING INSTALLATION
1. Installation of Regulator Assembly and water hookup
Procedure a. Tie into the water supply line under or near the
service case or floral display by using either a
compression or sweat “Tee” fitting with a 1/2"
FPT. (In cases of new store construction, the
appropriate 1/2" FPT fitting may already be
stubbed up under the case).
b. Screw the provided 1/4" x 1/2" MPT gray plastic
push-in filing into the 1/2" FPT water fitting.
c. To connect tubing for water, push one end of the
1/4" black poly tubing into the plastic push-in
fitting at the Tee”. Measure and cut tubing to
length and insert the opposite end of tubing into
the 1/4" push-in fitting on the Regulator
Assembly marked “CITY WATER”.
d. Connect another length of black poly tubing to
the push-in fitting (or plastic push-in “Tee” for
SCH-2) labeled ‘WATER” on the Regulator
Assembly. Measure and cut this piece of tubing to
length and connect the opposite end to the
push-in elbow fitting on the back of the nozzle
assembly. It may be necessary to drill access
holes through the bottom of the case for the
tubing lines - if so, ensure these holes are sealed
with silicon or similar substance.
TECHNICAL PROCEDURES ARE NOW COMPLETE
2. Start-up, Testing and Adjustment Procedures
a. Turn water on. Pressure gauge on Regulator
Assemblies should read approximately 1-4 psi.
b. Set Timer at each station for a 60 second “On
Time” and I minute “Off Time” cycle. (SEE
ATTACHED CONTROLLER SETTING
INSTRUCTIONS!) This setting, is for testing, on]
and will allow enough time for the water to 1111
the line and reach the nozzle.
c. Plug in the Controller to the 115V outlet.
Compressor and solenoid valves will activate and
plumes from nozzles will independently appear
shortly thereafter.
d. If humidity plume is too light or too heavy. Adjust
the Regulator accordingly. Adjust water pressure
by lifting up the yellow locking cap on the top of
the Regulator and turn clockwise (to increase
pressure) or counter- clockwise (to decrease
pressure). Make Regulator adjustments ONLY
when system is running. Push down on cap to
relock the regulator on the desired pressure.
e. A desired setting would be a pressure that
provides a solid constant plume from the
nozzle(s), but shuts off cleanly when the cycle
ends. If the nozzle(s) continue to emit a stream
of water or drip at shut-off, the pressure should
be decreased.
f. On completion of testing/adjustment, reset
Controller to recommended “On/Off ’ settings
as per Owner’s Guide which is included in the
packing carton.
g. Carry out training on tip cleaning and Timer
settings with department manager and/or staff.
3.

Recommended operation times: You should adjust your
humidification time for your stores needs~ This is because
each service case and floral display differs in temperature,
humidity, case style and volume. See chart below for sample
timings,
APPLICATION OFF TIME ON TIME
Seafood 5 min 30 sec
Meat 5 min 30 sec.
Deli 10 min. 30 sec.
Floral 10 min. 60 sec
Humidification nozzle assembly:
The humidification nozzle assembly is typically located at
one end of the service case aimed towards the opposite
end. The humidification nozzle is specially designed to
precisely mix air and water providing the desired humidity
level.
System maintenance and cleaning: (See also
attached Cleaning Instructions) It is recommended
that you clean the humidification nozzle (tip) periodically,
especially in areas with water that contain a high content
of solids. Unscrew the hex nut and remove the air and
fluid caps from the main nozzle body, Soak the caps in a
hot water and Efferdent@ solution for approximately 20
minutes, rinse and replace.
Remote timer operation; (See also cdtached Timer
Setting Instructions) The remote timer has two dials
used for setting times. The dial labeled “T ON” represents
the amount of time the operating cycle is to remain on.
Each number equals one minute, The dial labeled “T OFF”
represents the delay between operating cycles. Each
number equals one minute. Example: If you want two
minutes of mist every ten minutes, set the dial labeled “T
ON” at 2 and set the dial labeled “T OFF” of 10.
Tr oubleshooting:
See attached drawings and helpful tips, however should any
further assistance be required, please call Fractal Inc, Service
Dept. at 1-800-338 6478.
