CTP10-10E

Overview

The Alto-Shaam CTP10-10E is an electric CT PROformance combi oven that brings steam, convection, combination cooking and retherm together in one appliance. Alto-Shaam describes Combitherm ovens as capable of performing work associated with a convection oven, kettle, steamer, fryer and smoker. The CTP10-10E is intended for commercial food production where cooks need several cooking methods and repeatable controls in a single oven.

The unit has capacity for eleven full-size or GN 1/1 pans, or eleven half-size sheet pans, loaded one row deep. Its product maximum is 120 lb, with a maximum volume of 75 qt (95 L). Five wire shelves are included; additional wire shelves are required to reach maximum capacity.

Key Features

• Four cooking modes: steam, convection, combination and retherm.
• Programmable touchscreen control: save and run programmed cooking procedures.
• USB recipe transfer: upload or download recipes through the USB port.
• Absolute Humidity Control: select humidity from 0–100% to manage food quality, texture and yield.
• Automated cleaning: five fully automated cleaning cycles are listed as standard. The manual describes tablet-based cleaning and an optional automatic liquid-cleaning system.
• Rinse access: a front-accessible, retractable rinse hose is included.
• LED illuminated door handle: provides visual notification of oven status.
• CoolTouch3 triple-panel glass door: the specification says it keeps heat inside, keeps the glass cool to the touch and provides 15% greater thermal retention.
• SafeVent: automatically vents steam at the end of a cooking cycle.
• Core temperature probe: a removable, single-point, quick-connect core temperature probe is standard. A sous vide probe and a factory-installed hard-wired multi-point core probe are listed as options.
• Emissions and listing: the specification reports condensable particulate matter emissions of 0.77 mg/m³ when testing 11,660 beef patties, below the stated EPA test method 202 maximum allowable level of 5.0 mg/m³. It also states the product is UL listed under KNLZ in the U.S. and Canada.

Installation & Requirements

The specification gives the following clearances for the CTP10-10E: 20 in (508 mm) at the top; 0 in (0 mm) at the left; and 0 in (0 mm) at the right for non-combustible surfaces or 2 in (51 mm) for combustible surfaces. It lists 18 in (457 mm) as recommended service access, 5-1/8 in (130 mm) at the bottom and 4 in (102 mm) at the back. A separate 4-5/16 in (109 mm) option is also shown in the clearance information.

The electrical choices shown on the specification are 208–240 V single- or three-phase, 380–415 V three-phase, and 440–480 V three-phase. The available configuration must match the unit’s electrical specification. The supplied product information does not provide an amperage or a detailed field wiring procedure.

A Ventech Type 1 hood with condensation is described with this model’s exterior dimensions. Alto-Shaam states that Ventech condensation technology condenses steam and captures grease-laden air, vapours and smoke, and that the hood can eliminate the need for a traditional kitchen hood. Ventech PLUS is listed as an optional hood accessory and adds a HEPA filter. Hood field installation is extra when the factory-authorized installation program is selected. The listed installation choices are that program, available in the U.S. and Canada, or an installation start-up check through an Alto-Shaam authorized service agency.

Operation

Select among steam, convection, combination and retherm modes using the programmable touchscreen controls. Cooking programmes can be transferred by USB. Absolute Humidity Control provides a selectable humidity range of 0–100%. The standard removable, single-point quick-connect core temperature probe is available for probe-based cooking; the manual also includes recipe guidelines using cooking times, temperatures and probe targets for a range of foods.

Recipe examples in the operator’s manual include hard-boiled eggs at 212°F for 12 minutes and rice at 212°F for 23 minutes. These are examples from the manual’s recipe guidelines, not guaranteed cooking outcomes; food size, load and preparation can affect results. The manual cautions operators to use care when opening a hot oven door. It also warns against handling pans containing liquid or semi-liquid products positioned above the operator’s eye level because of scald risk.

Cleaning & Maintenance

The oven has five automated cleaning cycles. Tablet-based automatic cleaning is standard; automatic liquid cleaning is an option. For the optional liquid system, the manual lists five cycle levels: Rinse (20 minutes), Light (30 minutes), Normal (1 hour 20 minutes), Heavy-duty (2 hours 6 minutes) and Heavy-duty PLUS (3 hours 30 minutes). Side racks and shelves can remain inside during liquid cleaning. The manual says to ensure the water is on and enough liquid cleaner is available before starting a cycle.

For tablet cleaning, the manual instructs operators to wear rubber gloves, remove solid waste from the drain screen and oven interior, and place tablets in the drain before reinstalling the drain screen. Tablets placed on the drain cover or oven floor may not dissolve properly and can cause interior deterioration. If the oven is too hot to start cleaning, the manual says to open the door and allow it to cool below 150°F (66°C). Use authorized Combitherm oven cleaner only; unauthorized products may discolor or harm interior surfaces.

The manual directs operators to remove solids from the drain screen routinely to help prevent blockage. It advises cleaning the door gasket daily with a hot, soapy cloth because fats, particularly chicken fat, can weaken the gasket. It also says to leave the door slightly open at the end of the production day to relieve pressure on the gasket, and to clean the hinges routinely. For monthly descaling, the manual specifies putting 7 oz of Scale Free cleaner (Ce-27889) in the drain, running a heavy-duty cleaning cycle, rinsing the interior—including behind the open fan guard—and then running a rinse cleaning cycle.

The operator’s manual describes cleaning the probe, cable, prongs and holding bracket with a clean cloth and warm detergent solution, wiping away detergent with clean rinse water, sanitizing with an alcohol pad or food-contact-surface sanitizing solution, and allowing the parts to air dry. It also calls for wiping the probe with an alcohol pad before inserting it into a new food product. The manual warns not to steam-clean, hose down, flood or use a water jet on the oven; it states that failure to observe this precaution will void the warranty.

Weekly maintenance information in the service manual calls for inspecting the convection elements on electric models. The stated procedure includes removing wire shelves and the left side rack, opening the fan guard and checking the elements for cracking, grease or carbon buildup, scale buildup and major deformation.

Troubleshooting

If a Ventech hood is fitted, the service manual identifies E101 as a ventless hood fault with no pressure and E102 as a fault indicating filters are not present. Listed checks include confirming that filters are installed and not clogged, checking hood-fan operation, and checking the filter and pressure switches. The manual says a cooking cycle cannot start while these faults remain unresolved.

For a cleaning system that is not operating, the service manual’s troubleshooting sequence checks whether the Y4 cleaning pump is being energized and running, whether cleaning water reaches the pump inlet and water manifold, and whether water reaches the injection pipe. Listed possible checks include confirming the condensate-pan clean-out hose is unplugged, checking the Y2 cooling-water solenoid, inspecting the hose between the Y4 pump and water manifold, and clearing an obstruction at the injection pipe. These troubleshooting checks are service information; the manual’s safety warnings require proper care when servicing the appliance.
