CMP62G

Overview

The Rational CMP62G CombiMaster Plus 62 G is a gas-fired combi-steamer for commercial kitchens. Its cooking cabinet holds 6 x 2/1 GN containers or grids, with lengthwise loading also accommodating 12 x 1/1 GN. It can prepare food with steam, hot air, or a combination of the two, making it suitable for kitchens that need several cooking methods in one appliance.

The specification lists a typical output range of 60–160 meals per day. Its climate management system measures humidity and provides five-stage setting and regulation. The CMP62G also has a core temperature probe, programmable cooking settings, and three automatic cleaning programs.

Key Features

• Three cooking modes: Steam, hot air, and a combination of steam and hot air. The specification gives a temperature range of 30°C to 130°C for steam and 30°C to 300°C for hot-air and combination cooking.
• Humidity management: ClimaPlus climate management uses humidity measurement with five-stage setting and regulation.
• Programmable cooking: The unit allows 100 cooking programs, each with up to six steps. Five fan speeds are programmable.
• Core temperature measurement: A probe measures core temperature. The specification also lists optional sous-vide and externally attached core temperature probes.
• Air circulation and cooling: Dynamic air mixing supports cooking, while a Cool Down function cools the cabinet fan quickly. The integral fan impeller brake is listed as a working-safety feature.
• Cleaning and diagnostics: Three automatic cleaning programs, a diagnostic system with automatic service notices, and a menu-guided user descaling program are included in the specification.
• Other listed features: Integral USB port for HACCP data output and software updates; an integral grease extraction system requiring no additional grease filter; a high-performance fresh steam generator; and automatic, active rinsing and drainage of the steam generator by pump.
• Cooking cabinet and loading: The specification describes a seamless hygienic cabinet with rounded corners and a splash guard. Removable, swivelling grid shelves have 68 mm rail spacing. Lengthwise loading accepts 2/1 or 1/1 GN accessories, including 18 x 26 inch accessories.
• Door and controls: The mode selector is separate from temperature, core-temperature, and time settings. The LED display is described as visible from a distance. The door handle has right/left and slam functions; a left-hinged door and safety door lock are listed as options.
• Other listed options: Ethernet interface, lockable control panel, control-panel protection, special voltages, and connection to energy-optimising systems. A potential-free contact for operation indication is included with the energy-optimising-system connection option.

Installation & Requirements

Plan the installation around the CMP62G’s stated water, drain, gas, and electrical connections. The specification calls for a 3/4-inch pressure-hose water connection, flow pressure of 150–600 kPa, a DN 50 mm drain, and a 3/4-inch NPT gas connection. Its stated electrical connection is 1 NAC at 230 V and 50/60 Hz, with a 1 x 16 A breaker and 3 x 2.5 mm² cable cross-section. Other voltages are listed as available on request.

The specification states that copper wiring is required and that installation must comply with local electrical, plumbing, and ventilation codes. It recommends 500 mm left-hand clearance for service and maintenance. Where heat sources affect the left side, the stated minimum is 350 mm. The connection diagram identifies a steam vent pipe of DN 60 mm, a gas connection, and separate exhaust pipes for the steam burner and hot-air burner. It also shows a minimum distance of 50 mm for the identified exhaust-pipe arrangement. Have the installation checked against the appliance’s applicable documentation and local requirements.

The specification lists optional accessories such as GN containers, trays, grids, stands or cabinets, a thermocover, transport trolley, grease drip container, draft diverter with silencer, and catering kit. These are accessories, not included capacity claims for the oven.

Operation

Select steam, hot-air, or combination mode, then set the cooking temperature and time using the separate controls. The specification gives the mode-specific temperature ranges in the specifications above. For steam cooking, the listed range is 30°C–130°C; hot-air and combination cooking each have a listed range of 30°C–300°C. Climate management measures humidity and provides five-stage regulation, while the probe supports core-temperature cooking.

Operators can save up to 100 cooking programs with as many as six steps per program, and set five fan speeds as programmable settings. The unit’s USB port is listed for HACCP data output and software updates. The specification also describes automatic adaptation to the installation location, including height and climate, and a demand-related energy supply using a modulating, low-noise high-performance blower burner system.

Cleaning & Maintenance

The CMP62G specification lists three automatic cleaning programs, a diagnostic system that displays automatic service notices, and a menu-guided user descaling program. It identifies manufacturer cleaning and rinse-aid tabs as a working-safety feature. The listed high-performance steam generator is automatically rinsed and drained by pump.

The supplied installation and operation manual in the provided materials is titled for the CMP101G, not the CMP62G. Its model-specific operating and cleaning instructions should therefore not be assumed to apply to this oven without confirming that they match the appliance. Use documentation appropriate to the CMP62G for cleaning procedures and service work.

The CMP62G parts catalogue identifies steam-generator drain hose part number 44.01.241. Confirm the appliance’s exact configuration and part fitment before ordering replacement components.

Applications

The CMP62G’s steam, hot-air, and combination modes suit commercial food preparation that calls for different cooking methods in one cabinet. Its 6 x 2/1 GN capacity and listed output range of 60–160 meals per day make it relevant to restaurant, hotel, institutional, and catering kitchens handling multiple GN pans or grids. GN containers, trays, and grids are listed as accessories.
