Important CAUTIONS & WARNINGS
General:
1. This Installation & Operating Manual contains important instructions and safety information on the High Capacity
Wall Freezer (HCWF). Read and understand the contents of this manual before attempting to: Uncrate, Install,
Operate, and Clean or perform Routine Maintenance.
2. The HCWF is designed for the temporary frozen storage and easy access to frozen sh patties and other frozen
product at commercial restaurants only. Franke authorizes no other use.
3. The HCWF may NOT be used for long term storage, only temporary storage of frozen product between the walk-in
freezer and fryer or grill station production.
4. The HCWF is designed for installation and operation indoors, in a restaurant kitchen area protected from weather,
excessive heat, excessive humidity and corrosive salt air.
5. Only persons over 15 years old may operate this equipment, following all safety and operating instructions.
Plesae read and understand all of the WARNINGS, CAUTIONS and NOTES listed below.
During Installation
This equipment must be installed by qualied personnel, in compliance with all manufacturers’ instructions and local
building, food safety and electric codes.
CAUTION! The shipping carton and pallet have banding under tension, nails or staples and possibly wood splinters.
When uncrating, wear gloves and eye protection to reduce the risk of injury.
CAUTION! The HCWF-28 model weighs 200 lbs. or 91 kg. Do not attempt to remove this unit from the shipping
carton or pallet without the help of others.
CAUTION! The HCWF-28 is designed for wall mounting and provided with special mounting strips to secure the
unit to a wall. Installer must be qualied to evaluate (mounting) wall construction, supply suitable wall anchors and
securely mount the freezer per the instructions provided. Improper mounting could result in personal injury, freezer
damage and damage to equipment located below the freezer.
When Loading Product
Always use disposable gloves when removing frozen product from the freezer, to avoid potential cross
contamination.
Important Product Loading Tips:
1. DO NOT over-ll the High Capacity Wall Freezer. This freezer requires good air circulation to maintain uniform
frozen temperatures.
2. DO NOT let box aps or inner plastic bags block or obstruct the openings or vents in the top of the storage
compartment. Blocking those openings may raise freezer compartment temperature and require the compressor to
work harder
NOTE: Recommended maximum HOLD time for all products is 24 hours.
CAUTION! Do not allow freezer door to remain open for any longer than the time required to remove the frozen
product required. Keeping the door open will raise freezer compartment temperature, require the compressor to
work harder and potentially result in a FOOD SAFETY problem.

During Store Closing Procedure
1. Before closing, all remaining frozen product must be returned to long-term freezer storage.
2. This equipment must not be cleaned with a high-pressure water jet or steam cleaner.
3. Use only Cleaning and Sanitizing Agents approved by McDonald’s and specied for this application in their
restaurants.
NOTE: Never defrost the freezer by scraping the inside walls, regardless of how much frost is present. The HCWF-
28 is programmed to defrost every three hour of compressor run time. That defrost time interval will vary with
product load and how often the door is opened.
During Periodic Maintenance
WARNING! Verify the freezer is disconnected from the power source before attempting any preventive
maintenance. Failure to disconnect the electric power could result in electric shock, burns, other injuries or death.
CAUTION! The ns on a condenser coil are very sharp, and some refrigeration lines can be very hot, resulting in
possible cuts and/or burns. Avoid physical contact with the ns on the condenser coil or any related refrigeration
lines. Gloves are recommended when cleaning the condenser coil.
Basic Troubleshooting:
1. Store Personnel authorized “troubleshooting” on the HCWF is limited to the steps and procedures outlined in

1 Installation
1. Remove Freezer from Shipping Carton
This unit will arrive in a skid-mounted carton.
CAUTION! The shipping container may have staples and will have banding under tension, which can cause
injuries. Wear gloves and eye protection to reduce the risk of injury when removing the carton.
– Cut the plastic banding using heavy scissors or tin snips.
– Use caution to avoid contact with banding, when cut.
– Lift cardboard carton straight up and off unit.
2. Leave Unit on Skid Until Ready to Wall-Mount
CAUTION! The unit weighs 200 lbs (91 kg). Do not attempt to remove it from the shipping skid without assistance.
– Peel the protective white plastic lm from all stainless steel surfaces (front, sides, bottom and
compartment interior).
3. Remove Packing & Loose Components
The High Capacity Wall Freezer has one compartment door and three interior wire shelves that have been
secured so they won’t open or shift during shipping. Remove any tape securing the door. Remove any foam
blocking and tape used to secure the product storage shelves. The shelves can be removed to lighten the unit
during wall mounting.
4. Determine Freezer Wall Mounting Location
Identify the wall-mounting location, per the store equipment plan.
The High Capacity Wall Freezer is typically mounted immediately right or left of the Fry Station.
5. Electrical Preparation
Before you wall mount this unit, locate the appropriate 120-volt power outlet, typically the closest wall outlet. A
ten-foot power cord with grounded plug is provided with the Freezer. This cord will be shipped coiled inside the
open-top compressor compartment.
6. Wall Structure & Surface Preparation
The mounting wall must be capable of supporting 100 lbs. per linear foot. If drywall construction is evident, the
wall may need reinforcing with 1/2-inch thick plywood. Cut plywood to size and securely anchor it to the wall
structure (studs). A minimum of two wall studs are required for proper anchoring.

7. Wall Mounting the Fillet Freezer
– A steel offset mounting strip has been
provided for wall mounting this unit. This
mounting strip will engage the full width of the
freezer case top-rear frame/ange (Fig 1).
– Locate center point of desired case-mounting
position on the wall surface. Measure up 80”
from the nished oor.
– Place the bottom of the mounting strip at
that measured height, against the wall and
on-center with your mark. Level the mounting
strip with a small spirit or laser level. Mark
location of the ve screw holes in the
mounting strip.
– The mounting strip must be anchored to a
minimum of two wall studs for proper support.
For new store installation, verify if mounting
wall has plywood backing.
– Drill ve pilot holes in the anchor wall.
– Secure mounting strip to wall using No.12 x
2” long [minimum] wood screws. Make sure
top edge of strip protrudes from wall, so
ange on freezer can slip behind that strip.
Recheck level of mounting strip (Fig 2).
– Get help and lift unit from sides. Lift it up to
a height that will clear the mounting strip
with top/rear frame ange on cabinet, then
slowly lower case ush with wall, to securely
engage mounting strip along its full length.
IMPORTANT: Ensure unit frame ange slips
behind the mounting strip, while you continue
to supporting weight of cabinet.
– A stainless steel ‘L’ nish bracket is provided
to provide additional case support and a
clean nished look below the freezer. Hold
nish bracket against the wall, abutting the
case bottom. Secure strip with pre-drilled
holes to wall using the stainless steel
mounting screws provided (Fig. 3).

– Install four or ve screws to the refrigeration
compartment top brace. Drill pilot holes as
needed. Use No.12 x 2” long [minimum]
wood screws to secure top frame to wall
(Fig. 4).
– Span the unistrut across two ceiling trusses
above the drop ceiling (Fig. 5).
– Screw the all thread into the nut sert
attached at the top of the freezer and behind
the evaporator area (Fig 6)
– Secure the all thread to the unistrut with
supplied hardware (Fig 7).
– Cover the exposed all thread between the
HCWF and the drop ceiling with the split
plastic tube.
– Remove and uncoil the power cord from
refrigeration compartment. Plug it into the
120-volt/60-Hz outlet identied earlier. Any
excess power cord can be coiled inside the
refrigeration compartment, but away from
fan and hot coils. Use plastic wire ties, as
needed.

8. Initial Cleaning & Shelf Mounting
Clean all interior and exterior surfaces of the
freezer using approved McDonald’s cleaning
chemicals, according to instructions.
The High Capacity Wall Freezer comes with
three wire form shelves that slide onto right and
left shelf supports. The shelf supports have six
adjustable shelf positions. Slide the bottom shelf
into the nonadjustable bottom position. The
middle and upper shelves can be positioned to
accommodate different frozen food boxes or
packaging, as needed (Fig 9).
IMPORTANT: The shelf support system helps
maintain an air gap and good cold air circulation
around the freezer compartment. Always use the
wire shelves and position them properly in their
shelf supports.

2 Operating Controls
1. Power-ON/OFF Switch
The HCWF is provided with a main Power-
ON/OFF switch mounted above the freezer
compartment, just left of the temperature
display/controller. The switch will light up when
the power is ON (Fig 10).
IMPORTANT: Never turn OFF the Power Switch
when the freezer is in use.
2. Temperature Display, Set Point & Manual Defrost
The digital temperature display shows the
actual unit operating temperature at all times. If
adjustment becomes necessary, the four buttons
on the digital temperature display are used to
change the target set temperature (Fig 11).
The HCWF internal thermostat maintains
the recommended frozen product storage
temperature range of 0° (zero) to –10° F [-18
to -23° C]. This thermostat is calibrated, set
and tested at the factory, prior to shipment from
Franke.
Bring Freezer Down to Holding Temperature:
As soon as the unit is plugged in, the compressor will start and the unit will begin to chill. Keep the freezer door
closed. Do not load any product until the freezer temperature display reaches 0 (zero) to –10° F [-18 to -23° C].
This initial cool-down may take 30-45 minutes.
NOTE: Once the freezer is down to operating temperature, the compressor will shut off. While the compressor is
off, the fan will cycle on and off to save energy, when the freezer isn’t being used.
In addition to the Power ON/OFF switch, the only operating control on the HCWF is the digital temperature display
and its four small buttons used to change the target set temperature (set point) of the freezer. Adjusting target
temperature may be necessary to compensate for higher or lower temperature or humidity in the kitchen, or the
close proximity of heat producing equipment. NOTE: The “set point” is the mid-point in the compressor-on…
compressor-off operating cycle, which is factory set at plus or minus (+/-) 2° F.
