1.3 ASSEMBLY AND LEVELING
When you receive your fryer it is completely assembled with the possible exception of the legs (or
casters). In some cases, if you have purchased a multi-fryer unit, some simple assembly may be
required.
1.3.1 Leg/Caster Installation and Adjustment
Installing the legs and leveling the fryer is done with a 7/16" wrench, socket,
and a large pair of water pump pliers. The legs must be installed before
connecting the unit to the electric supply. The legs provide the necessary
height to meet sanitation requirements. Attach the legs by performing the
following procedure.
a. Lay the fryer on its side being careful not to damage the element
junction box by pulling on it. Protect the outside of the fryer with
cardboard or a drop cloth when laying it down.
b. Attach each leg/caster with the hex head cap screws supplied with
the fryer. Each leg/caster requires four 1/4-20 x 5/8" cap screws.
c. Mount the screws from the inside of the fryer with the nut on the
outside of the fryer. The nuts have lock washers attached to them,
therefore it is not necessary to use lock washers.
d. When all four legs/casters are mounted, stand the unit up being
careful not to put too much weight on any one leg/caster. Adjust
the height and level the fryer by turning the leveling devices on
the leg/caster with the water pump pliers.
e. On units with casters, move the fryer to the desired location and
lock the wheels using the locking devices on the sides of the
casters.

1.3.2 Assembling Multi Fryer Systems
If you purchased a multi-fryer unit it could be shipped in more than one piece. To assemble the unit
follow the instructions below:
a. Unpack the units and move them close together. Remove the front panels from the fryers.
b. There are three joining strips to be attached to the units to make the units into one system.
These strips are attached in the rear, front, and upper front. Use the screws supplied with
your system to attach the strips. Secure them tightly to each unit.
1-3

c. Connect the filter return piping and the drain manifold. If possible test the pipes for leaks
before completing the installation.
d. Replace the front panels to complete the system assembly.
1.3.3 Basket Lift Access
The basket lift mechanisms are installed at the factory and do not need adjustment. If it becomes
necessary to gain access to the basket lift motors or linkage, the rear panel of the cooker must be
removed. The motors do not require periodic lubrication.
1.4 INSTALLATION
Although it is possible for you to install and set up your new fryer, it is STRONGLY recommended
that you have it done by qualified professionals. The professionals that install your new fryer will
know the local building codes and ensure that your installation is safe.
1.4.1 Installation Clearances
The fryer needs clearance around it for proper and safe operation. These clearances provide adequate
distance to prevent combustible materials from coming in contact with hot fryer surfaces. The
clearances shown are for cooker installation in combustible and non-combustible construction.
Combustible Non-Combustible
Construction Construction
Back 6" 0"
Sides 6" 0"
Floor 4-3/4" 4-3/4"
In addition to the clearances required for proper fryer operation, there must be at least 28 inches of
isle space in front of the fryer to remove/install the filter pan/module.
1.4.2 C0 2 Fire System
Your new fryer has a C0 2 tie in that is designed to be electrically connected to the building fire
protection system. The C0 2 tie in is an electrical connector built into the 24 VAC fryer control
system. To connect the fryer to the building fire system, remove the connector jumper.
CAUTION
Do not apply power to this connector. This connection must be used
with a normally closed relay type system.
Cut the jumper wire and splice the ends of the wire to the building fire protection system. When this
point is broken by the building fire protection system, the fryer will completely shut down. Once
shutdown a fire can be quickly extinguished.
1-4

1.4.3 Electrical Connection
The fryer must be electrically grounded in accordance with local codes. If
local codes do not apply follow the requirements of National Electrical Code
ANSI/NFPA 70-1990.
The electrical service used by the fryer must comply with local codes. If there are no local codes that
apply, refer to the National Electrical Code (NEC) to install the service. In Canada refer to CSA
Standard C22.1 Canadian Electrical Code Part 1 & 2, and local codes. The type of power supplied
to the fryer is dependent on the model of the fryer. While the fryers can be configured to accept a
variety-of electrical power, the heating elements are designed for a particular voltage range.
Before proceeding with installation, ensure that the switch(s) marked OFF-
ON-START are in the OFF position. Also ensure that all the circuit breakers
for the appliance(s) are OPEN or OFF. NEVER connect the fryer with power
applied to the power lines. Some appliances have more than one power
supply. Make sure they are ALL disconnected.
Your fryer is shipped with the internal wiring connected to support the voltage and phase
requirements ordered. You can verify the wiring configuration by comparing the schematic supplied,
with the fryer to the wiring arrangement of your fryer. Table 1 -2 provides a list of models and voltage
ranges along with the heating element part number for that voltage range. Check the fryer data plate
to ensure that the fryer you are installing matches the power to be supplied to it.
CAUTION
Connecting the fryer to the wrong power supply may cause damage to the
fryer and will void the warranty.
NOTICE
Fryers with the UFM, Built-In filter, basket lift, or dual power supply options
will require a 120 VAC, 15A, single phase, 60Hz electrical service. This
service is required for the above options to work. This service is in addition
to the fryer's main electrical service.

1.5 INITIAL ADJUSTMENTS
After your fryer has been installed as described in section 1.4, it needs to be checked and adjusted
to ensure that it will perform as designed.
1.5.1 Visual Checks
Before you begin filling and adjusting the fryer, perform the following visual checks:
a. After the fryer is in its permanent location, lock the rollers and check the levelness. Any
additional leveling that is necessary can be performed as described in section 1.3.
Heating Elements
Figure 1-2 Inside Fryer Tank
b. Check the temperature bulbs (thermostat/high-limit) and other fryer tank components to
ensure that the mounting screws are tight and all components are secure. Ensure that the
heating elements are down and in place. Figure 1-2 shows fryer tank components.
1-9

1.5.2 INITIAL CLEANING
When the fryer is shipped, many of its parts are covered with a thin coat of high quality shortening
for protection. Before the fryer is ready for cooking, it must be cleaned. This will remove the oil
coating and any foreign matter that may have accumulated during storage and shipment. After the
fryer has been installed and checked by a qualified professional, clean the fryer as described below.
NOTICE
Since this will be the first time the fryer is turned on since leaving the factory,
be observant for any unusual signs of trouble. Any time a new piece of
equipment is energized there, will be some odors as new components heat up.
This is normal. If odors persist or excessive smoke is seen, TURN OFF the
power to the appliance at the service panel. Have a qualified technician check
out the unit for the cause.
The heating elements MUST be covered with water or oil before they are
turned on. NEVER turn on the fryer unless the main elements are covered by
at least one inch of liquid.
All power supplies must be disconnected before servicing or cleaning the
appliance. Some appliances have more than one power supply. Make sure
they are ALL disconnected.
a. Check the drain valve to ensure that it is closed. Fill the fryer with water to the fill line
marked on the back of the tank.
b. Press the START side of the OFF-ON-START switch and release. The switch will snap
back to the ON position. Switch the Melt Switch to MELT OFF. Set the thermostat to
220°F. The HEATING ON light will be on while the elements are on. Bring the water
to a gentle boil.
c. If the fryer is equipped with a Pitco Matic® computer, use the Boil feature to clean the
fryer. To use the Boil feature, open the fryer's front doors and turn the power on by
pressing the START side of the OFF-ON-START switch. The switch will snap back to
the ON position. On the computer press the HOLD/BOIL switch. The computer will
energize the heating elements and bring the water to 190°F.
d. Allow the fryer to heat for 15 minutes. Add Pitco cleaner, stirring to ensure cleaner has
dissolved thoroughly.
1-10

NOTE
Do not leave the fryer unattended during cleaning. Never let the water level
go below the "Min Level" mark on the back of the tank.
e. Using the fryer cleaning brush, scrub the inside of the fryer to remove protective coating.
f. When cleaning is complete, Press the OFF side of the OFF-ON-START switch to turn
the fryer off. Drain the water into a container suitable for hot water and dispose of it.
g. When the tank has cooled, rinse it thoroughly with cool water. Continue to rinse the tank
until the cleaner has been rinsed thoroughly from the tank.
h. Using a clean dry cloth, wipe out all of the water. Be sure to completely remove all water,
because any residual water will cause hot oil to splatter out of the fryer.
CAUTTON
Fryers with mild steel tanks must be wiped down and coated with oil to keep
the tank from rusting. This must be done if the fryer is not going to be used
immediately.
'• Now 11131 Ae tank is clean, you are ready to fill and operate the fryer. Refer to 2.1 for
instructions on adding shortening to the fryer.
1.5.3 Thermostat Calibration Check - Backup Thermostat Only
The temperature settings on the thermostat knob must match the actual temperature in the fryer for
proper control of the produce being cooked. Fill the fryer with oil as described in 2.1.
a. Press the START side of the OFF-ON-START switch and release. The switch will snap
back to the ON position. Allow the computer to bring the fryer to normal operating
temperature.
b. Let the fryer cycle 4 to 6 times before checking the temperature. Open the front door of
the fryer to gain access to the backup thermostat.
c. Slowly turn the thermostat knob and listen for the thermostat to click. You can also feel
the thermostat when it clicks. Although the thermostat is not controlling the fryer, its
temperature probe is still sensing the temperature of the fryer.
d. When the thermostat clicks, compare the setting on the knob to the temperature reading
of tire computer. If the temperature on the thermostat is within 5°F of the computer
reading, the thermostat is calibrated. If the thermostat dial is more than 5°F away from
the computer reading, go to step e.
