WARNING

Improper placement of forks may damage
drainage piping. Use a spotter when placing
forks. Make sure that piping will not be dam­aged. Use J-Bars or Jacks if forks cannot be
used safely

2. Ensure lower body panels are removed be­fore lifting with a forklift. Serious damage will
occur if the body panels are not removed.

3. Make sure that fork spacing and width will not
damage drain or come in contact with piping,
or electrical lines

4. Be sure that the forks are long enough to
support beyond the center of the case but not
damage near components. Check for proper
balance before moving. A minimum fork
length of 36” is recommended for 68” wide
cases

Refrigeration

Refrigerant

The correct type of refrigerant will be stamped
on each merchandiser’s serial plate. The case
refrigeration piping is pressurized with a nitrogen
holding charge, leak tested and factory sealed.
Before making refrigeration hookups, depress
universal line valve (Shraeder Valve) to ensure
that coils have maintained pressure during ship­ment. In the case pressure was not maintained
contact your Hussmann Service Tech for further
assistance.

Serial Plate Location

Refrigerant piping

The refrigerant line connections are at the right
hand end of the case (as viewed from the front)
beneath the display pans. The merchandiser will
beforehand ensure an earlier cut hole through
the pod to exit the merchandiser for the refrigera­tion lines. After connections have been made,
make certain to seal this outlet thoroughly if not
sealed at factory already. Seal both the inside
and outside. We recommend using an expanding
polyurethane foam insulation.

Line Sizing

Refrigerant should be sized as shown on the
refrigeration legend that is furnished for the store
or according to the ASHRAE guidelines

Oil Traps

P-traps (oil traps) must be installed at the base
of all suction line vertical risers.

CAUTION

Refrigeration lines are under pressure.
Refrigerant must be recovered before
attempting to make any connections.

It is the contractor's responsibility to install

case(s) according to local construction and

health codes.

Miatech Fogging System

SOP MIATECH FOGGING SYSTEM

Q3-MV-BC-R SETUP AND INSTALLATION

Be advised, for case lineups co nsisting of two 8-foot cases (or other compatible combinations), the
fogger system may be shared over 2 cases to reduce cost. One case will be designated as the primary
case and will house the fogger system. Any secondary case will be directly adjacent to the primary case
and will share case control, fogging control and apparatus. A 12 foot case will always have a dedicated
fogging system.

These are the notable differences between the primary and the secondary case.

 The primary case will house the Danfoss AK-CC 210 controller (orange arrow) in the rear panel. The

secondary case will not have a controller.

 The primary case will have a large removeable access panel on the lower rear skirt (blue arrow). Behind

the access panel, there will be a tray to slide the fogger system into along with a set of GFCIs to plug both
the fogger system and the heated nozzles. The secondary case will not have an access panel, tray or GFCIs
underneath the case.

 The primary case will house the system clock and heat er relay behind the rear controller panel. There will

be n o clock or relay on the secondary case.

 The primary case will have 2 rocker switches (green arrow), one for lights, the 2

secondary case will have 1 rocker switch for lights only.

a. Physical location

i. Remove the rear skirt for easy access to the tray, GFCIs and case thru hole(s).

ii. When ready, connect the fogger power to the GFCI labeled “Fogging System”.

This circuit is switched at the case control panel as opposed to the adjacent GFCI
which is hot once the case power connections are made.

Figure 3: The provided tray directly behind the
access panel. Remove lower skirt for system
installation. The access panel is provided for ease
of system access during operation.

Figure 4: Provided case drop to route hoses and nozzle heater wiring.

2. FOGGER NOZZLE INSTALLATION

a. Heated nozzles must be utilized. Standard (non-heated) nozzles will freeze and render the

system inoperable. The bracketry design will not accommodate non-heated nozzles.

b. Gain access to the coil area by removing the deck pans. The coils, fans and refrigeration

piping will be exposed. Locate the nozzle mount ing bracketry

3. WATER AND AIR HOSE ROUTING

a. Trim the black hard plastic tubing (see figure 6, pg 3) surrounding the 3 lines coming out

of each heated nozzle, ahead of the case drop (figure 4, pg 2). Do not pass the hard
plastic through the case drop.

b. Pass the nozzle tubes and wiring through the case drop and ensure no excess tubing

remains in the case. Leave enough slack so that the tubes do not kink when passing
through the drop and nozzle service can be accomplished.

c. IMPORTANT! - Ensure that the water lines DO NOT COME IN CONTACT with the below

freezing temperature of the refrigeration suction lines.
d. Make the appr opriate water and air connections to the fogge r system under the case.
e. Make t he appropriate electrical connections for the nozzle heaters. Plug the heaters

into the provided GFCI when the fogger system is ready to run. Do not plug it into the

“fogging system” GFCI. Note: The heater GFCI is electrically hot once the case electrical

connections are made, therefore the nozzles will be heated once the heater is plugged in.

f. IMPORTANT! - Seal case drop with a silicone based sealant once installation is finalized.

Allow the recommended time to cure before first operation of the fogging system.

Figure 8: Do not plug the heater into the Fogging System GFCI and vice versa.

4. CASE SETTINGS

a. Defrost – IMPORTANT! – THE SUPPLIED CASE CONTROLLER WILL CONTROL DEFROST

AND IS PROGRAMMED AT THE FACTORY WITH THE SETTINGS BELOW. This case does

not need a defrost from the rack. A rack defrost will lead to erratic operation and
potential loss of product.

i. Danfoss controller defrost frequency (d03): 8 hours

ii. Danfoss controller defrost duration (d04): 30 minutes

b. Discharge air (for reference)

i. 30-32° (in type M ambient conditions 68° DB, 50% Rh) measured 2 hours afte r

c. Superheat

i. Target 3-5° for superheat.

d. Evaporator suction temp

i. IMPORTANT! - 24°. Lower temps may precipitate freeze-up of the fogger

e. Controller setpoints are as follows:

i. Setpoint (cutout): 35°

ii. Differential (r01): 1°

defrost. Will vary depending on time of measurement and actual store
conditions.

system and degradation of case performance. Higher temps may jeopardize
product temperatures.

NOTE: You may notice that the controller setpoint is higher than the specified discharge air temp. This is because the
controller air sensor has been placed in the return air stream under the deck pans. This was done because the fogger
spray into the discharge air confused the controller and led to erratic operation.

Figure 9: Air probe for controller setpoint located in return air stream on the primary case only.

5. IMPORTANT! - MIATECH AQUA FOGGER CONTROLLER SETTINGS:

a. Power switch: On
b. Water pressure: 5 psi
c. Mist time: 45 seconds
d. Off time: 3 minutes
e. Heaters plugged into proper GFCI socket (labeled at Heater)

6.

REVERSE OSMOSIS FILTER

Total dissolved solids to be less t han 100 PPM.

31

7. FIELD ELECTRICAL CONNECTIONS

a. IMPORTANT! - For primary/secondary case lineups; the secondary case doe s not have

controls for the suction solenoid or defrost air heater. Two sets of leads will be bundled
in both cases for a field connection when the cases are placed and bolted together.
Trim excess wiring and make the indicated electrical connections for t he solenoid and
return air heater as per below:

Figure 10: The dotted lines indicate the secondary solenoid and secondary return air heater.

Figure 11: Locate the 2 sets of leads in the rear raceway of both cases after case placement. Connect the
secondary case solenoid leads to the leads for the solenoid on the primary case. Do the same for the return
air heater.

32

b.

IMPORTANT! - Heater relay connection: T he return air heater ships from the factory

disabled. If a fogging system is installed, the return air heater m ust be connected. The lead
will be labeled as “Install to terminal 1 if fogging system is installed.”

i. The relay is located behind the rear panel of the primary case (green arrow).

ii. Make the connection of the unconnected wire to terminal 1 on the heater relay.

Figure 13: Green arrow is the Heater relay. Blue arrow is the Time
Clock. Re d arrow is the Danfoss controller.

Figure 12: Connect the unconnected lead (purple) to
terminal 1 on the heater relay.

 NOTE: The ro cker switch for the fogge r system is lighted. Press the lighted part of

the switch to turn the system on. If the light does not turn on when the switch
turned on, one or more of the conditions for fogging engagement is not met. The
following conditions will interrupt fogger operation:

o …the Grasslin Time Clock (blue arrow above) is in off mode. The factory

default off-time is 10pm – 6am CST (over night). This w ould be indicated by an open circle.
In figure 14, the program is engaged indicated by a closed circle.

o …the Danfoss controller is in defrost and the he a ter relay is

energized. An icicle with rain falling (below) will be indicated on the
Danfoss controller. The main display will show “- d -“.

When the circle i s filled, as in figure
14, the timer is in the on mode and
the fogger power is not interrupted
by the time clock.

33

Figure 14

8. SYSTEM CLOCK: The Fogging system has a clock located behind the rear raceway panel.

Figure 16: The system clock interrupts the fogging system during non­display hours. The factory settings are listed below. If different, the
store’s actual times should be programmed into the clock. The factory
clock setting is set to CST. Adjust to your time zone as necessary.

Figure 15: Grasslin FM1D20-120
programmable time clock to match store's
meat department display times with an
overlap.

The factory default settings are:

a. Clock factory set to CST

b. On: 6am – 10 pm

c. Off: 10pm – 6 am

The benefits of interrupting the fogger system are:

• The RO filter life will be extended

• An y ice build-up will be cleared by this interruption.

• The life of the case will be extended by reducing the total fogging time.

It is not recommended that product remain in the case overnight. The product should be covered, removed to
cold storage and re-stocked in the morning. However, if product is kept in the case, the clock should not interrupt
the fogging system operation and must be re-programmed.

IMPORTANT! Check with the store personal to understand if they will be removing product for night­time storage and if so, what are their display times. If the factory default fogging times and/or the
local time differ, the clock must be re-programmed.

- Basic quick instructions below. See Grasslin’s website for the full manual for model
FM1D20-120U.

https://www.graesslin.de/-/media/inriver/7272-8754.ashx/Timer-Instructions-EN

a. Make the case electrical connections to power time clock. A circle ¾ circle with a “1” will be displayed when

AC power is applied to the case. Confirm that the timer is in “AUTO” mode. This will be indicated with a
small arrow above the “AUTO”.

b. Adjust the time to match the current time by pressing the “Menu” button. Adjust up and down with “+” and

“-“ keys. Press the “OK” key to confirm the item and cycle to the next entry.

c. After the day of the week is set, the next step is to set the fogging time: “prog 1”. Change the fogger start

time for the morning as per the store’s display time. Continue to enter the evening turn-off time. Once

complete press the “Menu” button to exit programming.
d. The “OVR” button can be used to either turn off or turn on the fogger depending on its current state.
e. To permanently run the fogging system, the time clock will need to be reprogrammed to run 23 hours and 59

minutes. You will notice all of the hash marks from 0-24 are on.

Important Information

The Q3-MV-BC service cases 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Hussmann’sspeci­cations and combined with a properly maintained
fogging system hich will result in product life
mitigated from dehydration, shrinkage and dis­coloration. Below are a few guidelines to ensure
optimum performance and product life.

• Review the Case Spec Sheet and verify ther­mostat settings. Do not set temperature too
cold, as this causes product dehydration.

• Temperatures should be achieved by digi­tal thermostat and suction solenoid at each
case. Do not use EPR valves, liquid line
solenoids or electronic control devices of any
kind without consulting Hussmann or Miatech
specialistrst.Thesecontrolsallowtempera­ture swings causing product dehydration and
excessive energy consumption.

• Defrost is controlled by the provided Danfoss
AK-CC 210 controller. See spec sheet for
derost frequency and duration.

• Clean Fogging System, see Standard Oper­ating Procedure or reference proper system
operation manual.

• Work and rotate product - not to exceed a (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 case at 35° or below. Prod­uct deterioration is very rapid above 40°.

• Maintain sanitary conditions throughout the
meat holding, prep and working areas.

• Do not display product outside the load limits.

• 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 side is kept in good color (bloom)
condition. The meat can even be turned (3)
three and (4) four times.

• 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. Fog­ging system adds moisture to the case and
helps slow down the dehydration process.
The only other moisture in the case is the
product. A single level of meat in a case will
dry out faster than a fully loaded case with
two 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
temp (see Case Spec Sheet)

WARNING

Retighten glass along hinges after leveling

and rst time case is brought to full

operating temperature!

Re-Adjustment after initial startup

In addition to verifying that the hinges for the
front glass are tightened when the case is de­livered, recheck the hinges on the front glass
once the case has been brought to full operating
temperature.
Temperature can affect shapes and sizes of
materials involved and can cause changes in the

securetofthefrontglassandhinges.

CAUTION

Removing Deck Pans

Always use caution while removing deck pans
from merchandiser. Located below the deck
pans is a heating element to assist in the deforst
process. Due to the increased moisture from the
Fogging system, frost build up must be defrosted
by the heating element creating a HOT SPOT
near the front of the deck pan which if not care­ful could lead to injury from heating element. The
heating element will only run during defrost but
HOT SPOT will remain for some time after de­frost has completed. As a safe measure always
use protective equipment to remove deck pans.

Case Cleaning

Long life and satisfactory performance of any
equipment are dependent upon the care it re­ceives. To insure long life, proper sanitation and
minimum maintenance costs, the merchandiser
should be thoroughly cleaned, all debris re­moved and interiors washed down, weekly.

WARNING

TO PREVENT INJURY ALWAYS SHUT OFF
POWER DURING CLEANING PROCESS.

Exterior Surfaces

The exterior surfaces must be cleaned with a
mild detergent and warm water to protect and

maintaintheirattractivenish.NEVERUSE

ABRASIVE CLEANSERS OR SCOURING
PADS.

Cleaning Stainless Steel Surfaces

Use non abrasive cleaning materials, and always
polish with grain of steel. Use warm water or add
a mild detergent to the water and apply with a
cloth. Always wipe dry after wetting.

Use alkaline chlorinated or non-chlorine contain­ing cleaners such as window cleaners and mild
detergents. Do not use cleaners containing salts
as this may cause pitting and rusting of the stain-

lesssteelnish.Donotusebleach.

Clean frequently to avoid build-up of hard, stub­born stains. A stainless steel cleaning solution
may be used periodically to minimize scratching
and remove stains.

Rinse and wipe dry immediately after cleaning.
Never use hydrochloric acid (muriatic acid) on
stainless steel.

Interior Surfaces

The interior surfaces may be cleaned with most
domestic detergents, ammonia based clean­ers and sanitizing solutions with no harm to the
surface.

WARNING

Glass can cause bodily damage. Check
support hinges for periodic maintenance.
When glass is open, it can cause bodily
damage, take adequate safety measures to
protect shoppers.

Cleaning Bumpers

Clean Bumpers with household spray cleaners.

Cleaning Under Merchandiser

Remove lower body panels. Use a vacuum with
a long wand attachment to remove accumulated
dust and debris from under the merchandiser.

Cleaning Coils
NEVER USE SHARP OBJECTS AROUND
COILS. Use a soft brush or vacuum brush to

clean debris from coils. Do not puncture Coils!

Donotbendns.Contactanauthorizedservice

technician if a coil is punctured, cracked, or oth­erwise damaged.

ICE in or on the coil indicates the refrigera­tion and defrost cycle is not operating properly.
Contact an authorized Service Technician to
determine the cause of icing and to make proper
adjustments as necessary. To maintain product
integrity, if not done so already, move all product
to a cooler until the merchandiser has returned
to normal operating temperatures.
