I. INSTRUCTION FOR THE INSTALLER
Congratulations! You have just purchased a new Cadco Digital Convection Oven. Let’s go over some of the
basics before you start using your new oven.
1. DATA PLATE (Located on side of oven)
2. CERTIFICATION
2.1 The “MET” mark on our data labels and on our user manual refers to the following listings:
Certifications are listed under UNOX S.p.A., MET file #E112912, including XAFT series oven models.
http://corp.metlabs.com/safety/listing.asp
Class Number:
Class Number:
2831-03
2831-83
DESCRIPTION:
DESCRIPTION:
HEATERS-Cooking and Liquid - Stationary Type
HEATERS-Cooking and Liquid-Stationary Type-
Certified to the requirements of UL 197 (for USA)
and CSA C22.2 No. 9 (for Canada)
2.2 The “NSF” mark refers to listing including XAFT series oven models under UNOX SPA for NSF/ANSI
STANDARD 4: Commercial Cooking, Rethermalization and Powered Hot Food Holding and Transport
Equipment. http://info.nsf.org/Certified/Food/Listings.asp?Company=79610&Standard=004
3. INSTALLATION - PRELIMINARY OPERATIONS
All electrical connections and installation operations must be done by qualified personnel, and comply
with all existing codes.
3.1 CHECK THE LOCATION OF INSTALLATION
Verify the overall measurements and the exact position of the electrical and water connections (where
applicable) before installing the oven. Refer to the illustrations in the separate “technical data” document
for your model.
3.2 FEET ASSEMBLY
You will find the feet packed inside
your oven’s cooking cavity. The feet
must be used when your oven is in
operation. Never use your oven
without its feet properly installed,
unless the oven is on an oven stand.
Half size feet pop in Full size legs screw in over leg braces
Assemble the feet as shown. (Full size models come with tall legs that screw into place; all other models
come with shorter feet that pop into place.)
3.3 POSITIONING
Place your oven so the back and sides can be easily reached. This will make the electrical connections
and any servicing points easily accessible. Your oven is not designed for built-in applications or for side
by side positioning. Cadco suggests you leave a minimum distance of 4” between the back of the oven
and the wall to allow for the escape of moisture. The oven must be placed upon a support, a stand, or on
top of a counter made of non-combustible material. Never install the oven directly on the floor. If the
oven is placed near walls, dividers, kitchen cabinets, decorated edges or drapes, they must be made of
non combustible material.
3
3.4 REMOVE THE PROTECTIVE FILM
Carefully remove all the protective film from the external walls of your oven. Be sure to remove any
residual glue left on the outside of the oven with an appropriate solvent.
4. INSTALLATION
4.1 ELECTRICAL CONNECTION
• Connection to the electrical power source must be done according to all state and local codes. Before
connecting your oven, make sure that the voltage and the amps comply with those stated on the data plate
of your oven. Avoid using patch cords and multiple jacks.
• The appliance must be placed so that the connection plug to the outlet can be easily reached.
When the appliance is in operation, the power supply voltage must not diverge from the value of the
nominal voltage, written on the technical data plate, by more than + or – 10%.
• Ovens are equipped with cordset and NEMA plug (single phase; 120V or 208-240V, depending on oven
model.) It is sufficient to insert the plug in the proper outlet (the outlet must be suitable for the plug
assembled on the oven.)
4.2
WATER CONNECTION
(available on all digital models EXCEPT XAFT-111 & XAFT-130, per below)
• WARNING: The water supplied to the oven must be free from chloramine, or else with levels not
exceeding .5ppm. Any damage caused by chloramine within the water is not covered by warranty.
• WATER SUPPLY SPECIFICATIONS
♦ Water supply must not exceed 86°F, and must be potable.
♦ Water must have a maximum conductivity of 150 μS/cm. If greater than 150 μS/cm, use a filter to
avoid limescale and/or other minerals from depositing inside the oven.
♦ Water must have a hardness between 0.5° and 5°F (to avoid formation of lime deposits inside the
electric valve and inside the cavity).
• CONNECTION TO THE WATER NET: Full Size digital oven models (XAFT-188 & XAFT-195)
come with an electrovalve for direct water connection.
♦ A mechanical filter must be placed between the water system and the water connection of the oven.
♦
Before connecting the water pipe to the oven, flush it out with water, to clean the duct from any residue.
♦ A shut-off valve should be positioned between the water supply and the oven.
♦ Water used in the oven must have a pressure between 22 – 87 psi (150-600 kPa). If the pressure of
water supply at the inlet is too low (22 psi/1.50 bar), a pump with a suitable flow rate should be used
(minimum flow rate of 1.32 gpm (300 l/h).
♦ Cadco suggests you use a decalcification filter in order to maintain fan balance.
• AUXILIARY WATER PUMP (FOR CONNECTION TO AN EXTERNAL WATER TANK):
Half Size digital ovens with Dynamic control panels (XAFT-115 & XAFT-135) come with an EL080
Auxiliary Water Pump included, for manually pumping water from a bucket, water tank, or other
container. WARNING: Before using the water pump, always make sure that there is water in the tank.
Damage to the pump can occur if it is operated without water in the tank and it will void your warranty.
If the pump makes “groaning” sounds, it is probably due to lack of water in the tank or the pump is
simply running an air bubble through the system.
To install:
1) Part (1) is found in the plastic bag inside your oven cavity,
along with the oven feet.)
2) Connect the pipe (1) of the filter to the pump (3) by pushing it
onto the nipple of the pump sticking out of the back of the
oven, as shown.
3) Insert the filter into a water tank (such as Cadco model
XC655) or other water container.
4) Connect oven to power supply.
5) Use only decalcified water.
4
• Hot air and steam will exit the oven from the back exhaust port. During most cooking cycles, you will
have hot and humid exhaust coming out from this exhaust port (temperature and humidity of this exhaust
depend on the cooking parameters being used.) The steam that comes out of the exhaust port can also be
vented outside if desired.
II. INSTRUCTIONS FOR THE USER
Never allow grease splatters or spills to collect on the inside walls, floor, or ceiling of your oven. A
simple cleaning with soap and water is usually enough to keep your oven spotless and in “like new”
condition for years. Your oven should never be cleaned with a water hose or anything more powerful
than a spritz bottle. For tougher cleaning and built up grease, we suggest using Foam Plus® from
Discovery Products Corporation (Tel. 877.822.8500.)
1. INSTRUCTIONS FOR THE OPERATOR
You will find important information about maintaining and operating your new oven in this manual.
Please read the manual and become familiar with your new oven before you begin to operate it. Keep the
manual in a safe place and make sure everyone reads it before operating the oven. Please use only Cadco
authorized service centers and always require quality UNOX-OEM parts. Failure to comply with these
standards can compromise safety and will void your warranty.
2. NOTES FOR USE
• Your Cadco oven was designed to cook food and must be used only for that specific purpose. Any other
use may void your warranty. The usable operating temperature range is approx. 175°F to 500°F. It is
suggested that you allow about 2-3” between trays for proper air circulation during the cooking process.
Use your Cadco oven for:
♦ Baking all types of bread and pastry, both fresh and frozen.
♦ Cooking any meat, fish, or fowl.
♦ Rethermalizing any cooled or frozen cooked foods.
♦ Cooking (not steaming) any kinds of vegetables.
• Avoid salting your food products while they are inside the cooking cavity. Salt is very corrosive and
may, over time, damage the interior of your oven.
3. CONTROL PANEL
XAFT digital oven models are operated by pressing the
relevant spots (“buttons”) on the “Touch Control”
screen-printed keypad on the oven control panel.
Press ONLY with fingers. DO NOT press with any
other objects, such as knives, forks, etc...
This technology makes cleaning the control panel quick and easy, while guaranteeing maximum reliability
and durability and helping to avoid mechanical failure.
