Combi Oven Buying Guide for Seattle Restaurants

A combi oven combines a convection oven and a steamer in one cabinet. It can cook with dry heat, steam or both at once, so one oven can roast prime rib, steam vegetables and fish, bake bread, proof dough, reheat banquet plates and hold moisture in chicken and pork. For many kitchens it replaces a convection oven, a steamer and part of the range.

Many Seattle owners start by looking for a used combi oven, and many found the original Encore Seattle that way when it sold used restaurant equipment. Today Encore Seattle sells only new Atosa equipment. A combi is the one oven where buying used is the riskiest, and this guide explains why, then covers sizing, power, water, installation and cleaning.

New vs. Used Combi Ovens

A combi oven mixes high heat, steam and hard water every day. That combination is tough on parts, and most of the damage is inside where you can't see it.

What wears out on a used combi oven

Scale buildup: hard water leaves scale on the steam system and sensors. Heavy scale cuts steam output and can lead to costly repairs.
Control board and touch screen: heat and moisture damage electronics. A failed board is one of the most expensive repairs on any oven.
Sensors and core probe: worn or damaged sensors give bad temperature and humidity readings.
Door gasket and glass: worn gaskets leak steam and heat.
Fan motor and heating elements: run hard every service.
Pumps, valves and the cleaning system: skipped cleaning cycles leave grease and scale in the lines.
Power: a used combi built for a different voltage or phase may not run in your building.

The warranty gap

Most used combi ovens are sold as-is, with no service history. Every new Atosa combi oven on this page carries a 1-year parts and labor warranty.

The real cost of a used combi oven

Cost	Used	New Atosa
Purchase price	Lower up front	Higher up front
Pickup and delivery	Usually yours, and combis weigh 209 to 436 lb	Free freight with liftgate on orders of $500 and up
Steam system and scale	Unknown	New and clean
Controls and sensors	Unknown condition	New Smart Touch controls
Repairs in the first year	Paid by you	Covered by the 1-year parts and labor warranty
Energy use	Often older, less efficient	ENERGY STAR on the AEC-0621E, AEC-0711E, AEC-1011E and AEC-1021E

If you still buy used, check this first

Ask for service and descaling records.
Run steam, convection and combi modes and check for error codes.
Look inside the cavity and around the steam outlet for scale.
Check the door gasket, glass and hinges.
Confirm the voltage, phase and breaker size match your building.
Have a qualified technician install it.

Half Sheet or Full Sheet

Half sheet models (AEC-0511E, AEC-0711E, AEC-1011E) take 18" x 13" sheet pans or 12" x 20" hotel pans. All three share the same 31" W x 34-1/2" D footprint and only the height changes. Each shelf holds 39 lb.
Full sheet models (AEC-0621E, AEC-1021E) take 18" x 26" sheet pans, or two 12" x 20" hotel pans per level. Both are 36" W x 42-1/2" D. Each shelf holds 65 lb.

Count the pans you need at your busiest service, then add room to grow. Moving up in pans costs less than buying a second oven later.

Every model is 208/240V three-phase, runs from 86°F to 500°F and has a triple pane tempered glass door. All are cETLus and ETL-Sanitation listed, and every model except the AEC-0511E is ENERGY STAR certified. Atosa lists amps, kW and breaker sizes as a range for 208V and 240V.

Power, Water and Drain

Three-phase power is required. Have your electrician confirm 208V or 240V three-phase service and size the breaker from the table above.
Water inlet: 5/16" OD push-to-connect, with 30 to 90 PSI water pressure.
Drain: 1" ID / 1-1/2" OD. Plan a floor drain or approved drain nearby.
Treat hard water. Water treatment and regular descaling protect the steam system.

Cleaning Chemicals

Atosa says AEC Smart Touch combi ovens are approved for use with Atosa's own liquid combi cleaner and rinse agent. The ovens have twin chemical fill tanks and remind you when the cleaner or rinse is low.

Product	What it does	Case pack
AT10SK Starter Kit	Detergent and brightener to get a new oven started	2 x 32 oz
AT102 Detergent	Breaks down grease and food soil in the cleaning cycle	4 x 1 gallon
AT202 Brightener	Rinse agent that reduces limescale and helps the oven dry	4 x 1 gallon
ATD1 Descaler	Removes scale from the steam system	6 x 32 oz
AT1032 Foaming Degreaser	Non-caustic foaming degreaser for spot cleaning	6 x 32 oz

Installation

Use a licensed electrician and plumber for power, water and drain.
Install under an exhaust hood as local code requires. Combi ovens release steam and heat when the door opens.
Set it on a level stand or counter that can carry the oven plus a full load. A 10 full sheet model weighs 436 lb before food.
Leave service clearance at the sides and back.
Measure doorways before delivery. The full sheet models are 36" wide and 42-1/2" deep.

Cleaning and Care

Run the automatic cleaning cycle daily, or as often as your menu needs.
Keep the detergent and brightener tanks filled.
Descale on a schedule. Hard water areas need it more often.
Wipe the door gasket and glass daily.
Don't hose down or pressure wash the outside of the oven.
