themselves eliminate any danger. The instructions
or warnings they give are not substitutes for proper
accident prevention measures.
If you need to replace a part, use genuine Stoelting
parts with the correct part number or an equivalent
part. We strongly recommend that you do not use
replacement parts of inferior quality.

Section 2 - Installation Instructions
A. TOOLS NEEDED
• Level
• Screwdrivers and wrenches
• Straight edge
• Thermometer
• Stopwatch
• Belt tension guide
• Scale
• Refrigeration gauges
B. PRIOR TO INSTALLATION
1. On the startup form, complete the following:
• Buyer Information
• Distributor Information
• Authorized Service Provider Information
• Verify with Store Operator Checklist
• Freezer Configuration Information
2. Prepare a USB flash drive with your service contact
information:
a. Locate a copy of the service contact file (info.txt).
b. Modify the info.txt file with information from the
service company using the instructions in the file.
c. Put the service contact file onto the root level
of a USB flash drive (do not put the files into
any folder).
C. INSTALLATION
1. Uncrate the machine and remove the 3/8" bolts
holding it to the pallet.
2. Install the legs. Loosen the lock nut and screw the
legs into the base of the machine to a height of
about 3/4”. Set the machine in place.
3. Accurate leveling is necessary for correct drainage of
the freezing cylinder and to ensure correct overrun.
Place a bubble level on top of the machine at each
corner to check for level condition. If adjustment is
necessary, level the machine by turning the bottom
part of each leg in or out then tighten the lock nut.
4. The machine hasa basegasketthat mustbe installed.
Install the gasket with the seam to the back. Make
sure the angled side of the gasket is facing up.

Operators Manual #513674 4 E131-I2 & F131-I2 Model Machines
5. In air cooled machines correct ventilation is required.
The right side of the machine is the air intake and
left side is the discharge. Both sides must have 3”
clearance.
CAUTION
Failure to provide adequate ventilation will void
warranty.
In water cooled machines, make sure to use 1/2”
supply and discharge lines. Follow all local and state
codes for connecting the supply and discharge lines.
Turn on the water supply and check all connections
for leaks.
6. Open the rear panel and check the belt tension with
a Burroughs Belt Tension Gauge. The tension should
be 50-58 lbs. Adjust as necessary and check the
pulley alignment with a straightedge.
NOTE
Belt life will be increased if the new drive belts are
tightened after two or three weeks of operation.
7. Connect the power cord to the proper power supply.
Refer to the nameplate on your machine for proper
supply. The unit must be connected to a properly
grounded receptacle. The use of an extension cord
is not recommended. Do not use an adapter to
circumvent the grounding requirement.
WARNING
Do not alter or deform the electrical plug in
any way. Altering the plug to fit into an outlet
of dierent configuration may cause fire, risk of
electrical shock, product damage and will void
warranty.
