5User Manual | French Door Digital Air Fryer Oven | GTF3588
SAVE THESE INSTRUCTIONS
17. You may use foil or parchment
paper as a liner on the baking
pan. However, cut the liner so it
is fitted to the exact size of the
baking pan and is not raised above
or hanging below the pan, to
ensure the liner is not close to the
heating elements.
18. NEVER leave the liner on the
baking pan during preheating and
cooking, unless there is food on
the liner to weigh it down and
keep it safely secured in place.
19. Do not use the appliance for any
other purpose than described in
this manual. The use of accessory
attachments not recommended
by the appliance manufacturer
may cause injuries.
20. Do not place any of the following
materials in the oven: paper (other
than parchment paper), cardboard,
plastic, and the like. Extreme
caution should be exercised when
using containers constructed of
anything other than metal or glass.
21. Oversized foods or metal utensils
must not be inserted into the
toaster oven, as they may create a
fire or risk of electric shock.
22. During cooking, hot steam is
released through the air vents.
Keep your hands and face at a
safe distance from the steam and
from the air vents. Be careful of
hot steam when you open the
doors of the appliance.
23. Do not touch hot surfaces.
Use handles and protective

Before First Use
For customer service visit www.gourmia.com or call 888.552.00336
Before First Use
1. Remove and discard all packaging material, labels, and tape from the oven.
2. Thoroughly clean air fry basket, oven rack, baking pan, and crumb tray
with hot water, dishwashing liquid, and a non-abrasive sponge. Dry all
parts before use.
3. Wipe the inside and outside of the oven with a moist cloth.
Cord and Plug Safety
1. A short power-supply cord is provided to reduce risk of becoming
entangled in or tripping over a longer cord.
2. Extension cords may be used if care is exercised in their use.
3. If an extension cord is used:
• The marked electrical rating of the extension cord should be at
least equal to the electrical rating of the appliance.
• The longer cord should be arranged so that it will not drape over
the countertop or tabletop where it can be pulled on by children
or tripped over.
Electrical Polarized Plug
This appliance has a polarized plug (one blade is wider than
the other). To reduce the risk of electric shock, the plug is
intended to be used by inserting it into the electrical outlet
only one way. If the plug does not fit securely into the
outlet, reverse the plug and re-insert. If it still does not fit,
contact a qualified electrician for assistance. Do not modify
the plug in any way.

Before First Use
7User Manual | French Door Digital Air Fryer Oven | GTF3588
WARNING:
DO NOT place the oven against a wall or against other appliances. It is
important to leave at least 4 inches of free space above and around all
sides of the oven to allow for proper ventilation.
To avoid the risk of fire:
DO NOT place anything on top of the oven.
NEVER cover the crumb tray or the oven walls with aluminum foil or
parchment paper.
You may use foil or parchment paper as a liner on the baking pan,
however:
• Cut the liner so it is fitted to the exact size of the baking pan and
is not raised above or hanging below the pan, to ensure the liner is
not close to the heating elements.
• NEVER leave the liner on the baking pan during preheating and
cooking, unless there is food on the liner to weigh it down and
keep it safely secured in place.
When cooking greasy or drippy foods, use the baking pan instead of
the air fry basket
ALWAYS use CAUTION when opening the doors; hot steam may
escape!
The oven, accessories and food will be hot! DO NOT touch hot
surfaces. Use oven mitts when inserting or removing food from the oven.
Using Oil
When spraying food for a
crispier finish, we recommend
using cooking oil instead of
cooking spray, as the latter may
damage the accessories and
reduce the life of the appliance.
The oven may produce smoke
if you use oil and cook food at
a hotter setting than what is
recommended.
NEVER spray the heating elements or oven walls with oil.

Convection Tips
For customer service visit www.gourmia.com or call 888.552.003316
Convection Tips
See the FUNCTIONS CHART on pages 11-14 to see each functions' convection options.
• Foods that are covered benefit from the convection’s even heat and
will cook faster without any moisture loss.
• The high temperature air circulation produces roasted foods that are
golden brown on the outside and juicy and tender on the inside.
• Even cooking means that you can use more than one rack and you do
not have to turn foods or rotate baking trays.
Below are foods that benefit from the convection setting and when to use it:
Convection Bake: Convection Roast: Convection Broil:
Pies
pastries
cookies
biscuits
Meat
vegetables
whole fish
Meat, fish.
for melting cheese,
for browning the top
of casseroles
Pizza:
• Use the lower rack positions and check often so the cheese does not burn.
• Start with no convection then turn on convection for the last few minutes
to brown cheese.
Not recommended for:
• Custards and flans, souffles, cakes, quickbreads, breads
Additional tips:
• Make sure air can circulate around food and pans.
• Use trays, roasting pans, and baking pans with lower sides.
