Equipment Description

Your Groen Convection Combo™ has a stainless steel cooking chamber, an air heating compartment with electric heating elements and fan, a steam generator with electric heating elements, and a control compartment which houses other electrical components.

All major components of the Convection Combo™ are encased in a 16 gauge stainless steel cabinet. Glass fiber insulation, lines the cabinet at a thickness of 1½ to 2 inches (4 to 5 cm). A removable drip tray is located beneath the door.

Door hinges are reversible so that doors may open from the left or right side. Operator controls are located on the right side of the front panel.

Standard controls let you to operate the Convection Combo in any one of three cooking modes:

1. As a convection oven

2. As a self-contained, pressureless steamer

3. As a c ombination oven-steamer

Models CC10-E and CC20-E differ in cooking chamber size and capacity:

CC10-E: 4 steam table pans (12x20x2½”), or

7 half-size (13x18") US baking pans

CC20-E: 10 steam table pans (12x20x2½”), or

9 full-size (18x26") US baking pans

The smaller Convection Combo™ is available as a table-top unit (the single CC10-E). These units are also supplied on a stainless steel stand as models CC10-EF and (2)CC10-EF. The larger Convection Combo™ is always supplied with a stand as the single CC20-EF or the double-stacked (2)CC20-EF.

The Convection Combo™ Family: 1. Model (2)CC20-EF (Full-sized double-stacked unit on rigid stand),

2. Model CC-20-EF (Full-sized single unit on a convenient stand), 3. Model (2)CC10-EF (Double-stacked, stand-mounted, half-pan Combo, 4. Model CC10-EL single four inch leg-mounted. (Also available in tabletop (CC10-E) and stand-mounted (CC10-EF) versions.

Inspection and Unpacking

OM-CC-E

Your Convection Combo™ will be completely assembled in a heavy shipping carton or wooden crate, and attached to a skid. On receipt, inspect the carton or crate carefully for exterior damage.

CAUT ION SHIPPING ST RAPS ARE UNDER T ENSION AND CAN SNAP BACK WHEN CUT.

Carefully cut the straps around the carton and detach the sides of the carton from the skid. Pull the carton up off the unit. Be careful to avoid personal injury or equipment damage from staples which might be left in the carton walls.

Water Conditioning

It is essential to supply the steam generator with water that will not form scale. Even though the steam generator is engineered to minimize scale formation, scale development depends on the hardness of your water and the number of hours you operate the equipment.

In some areas, water is low enough in mineral content to avoid scale formation. But most water supplies are full of minerals which form scale. It is this scale which could lead to an early component failure.

Your water utility can tell you about the minerals in your water. The water going to the steam generator should have between 30 and 40 parts per million (ppm) total dissolved solids (TDS) and should have a pH (acidity rating) of 7.0 to 9.0. Please follow these simple precautions:

Do not rely on unproven water treatments

1. which are sold for scale prevention or scale removal. They don’t always work. The best way to prevent scale is to supply the purest possible water (30 -40 ppm TDS).

Write down the model number, serial number and installation date and keep this information for future reference. Space for these entries is provided at the top of the Service Log in the back of this manual.

CAUT ION THIS UNIT IS VERY HEAVY. YOU SHOULD GET HELP AS NEEDED TO LIFT T HIS WEIGHT SAFELY.

When starting installation, lift the unit straight up off the skid. Check packing materials to make sure loose parts are not discarded with the material.

softener will provide longer generator life, higher steam capacity, and reduce maintenance requirements.

If you notice a slowdown in steam production,

3. have the unit checked for scale build-up. Heavy scale reduces the unit’s ability to boil water, and can even cause heating elements in the steam generator to overheat and burn out.

MINIMIZE SCALE PROBLEM S, BY USING AND MAINTAINING A SOFT ENER, AND BY CLEANING THE STEAM GENERATOR REGULARL Y.

Groen Convection Combo™ ovens are also available with an option for two separate water connections — one for the steam generator (soft water), the other for the spray condenser (untreated water). The steam generator only uses 14 to 31% of a combination oven’s water.

Since softener systems are typically sized by total GPH (gallons per hour), the second connection could reduce treatment requirements by up to 80%, resulting in significant savings.

2. If your water contains scale-forming minerals, as most water does, use a well-maintained water softener. Whether an exchangeable softener cartridge or a regenerating system is chosen, a regular exchange schedule is essential.

Installing a water meter between the softener and the steamer will provide an accurate gauge of water use, and will help determine when to exchange cartridges or regenerate the softener. Using a water

Terminal block

1. Mounting

If you wish to install a Convection Combo™ on top of another, you should obtain a double stacked unit from the factory.

If the unit does not have a factory-installed stand, the installer must provide a table, stand or counter which is strong enough to support the unit. Use of casters is not recommended.

To avoid drainage problems, level the unit front to rear, or provide a slight pitch to the rear.

Bolt the unit to the table, stand or counter top, using the mounting holes in its base.

2. Electrical Supply Connections

Panel Removal

The right side panel must be removed to gain access to the wiring and control compartment. Remove the two screws at the bottom of the panel. Slide the panel toward the front of the unit, lift it and set it aside.

Supply Voltage

The CC10-E must operate at the rated nameplate voltage, plus or minus 10%.

Phase Select Plug (Units manufactured

before 1996)

Locate the phase select plug assembly on the wiring harness from the relay board. This assembly is black, blue and red. Refer to the labels located below the motor and above the distribution block for the correct phase connection.

The terminal block for incoming power is located at the back of the control

compartment.

WARNING

WHEN CONNE CT ING FOR SINGLE PHASE OPERAT ION, DO NOT CONNECT ANY WIRE TO LINE 3 (T HE TERMINAL FART HEST LEFT ). T HIS WILL CAUSE A SHORT CIRCUIT .

The ground terminal is found on the relay bracket below the terminal block. The

Convection Combo™ must have a separate ground wire for safe operation. The ground wire must be at least 10 AWG (2.6 mm).

e. Supply Wire

The type of wire needed is determined by finding the operating voltage and phase from

the unit’s back data plate and (on pre-1996 models) phase select connector. Refer to the “Electrical Supply Connection” label on the back of the unit for correct wire size and insulation temperature rating.

The specified wire must be used to comply with Underwriters Laboratories and National Electric Code requirements.

Each current-carrying conductor must have overcurrent protection. Refer to the label on

the back of the unit for proper wire size and type. Watertight connections are required.

3. Water Supply Connection

A check valve (back siphonage device) must be installed in the incoming cold water line in keeping with local plumbing codes. Water line pressure should be between 30 and 60 PSI (210 and 410 kPa). A pressure regulator is required above 60 PSI (410 kPa).

A ¾ inch (19 mm) NH (garden hose type) connector is required to connect the water supply to the water inlet valve. The water feed line diameter may not be less that ½ inch (13 mm). Use a washer (or if necessary, two washers) in the hose connection. Do not allow the co nnection to have any le ak, no matter how small.

A 1½ inch (4 cm) hose may be attached to the provided drain elbow with a clamp. Do not use plastic pipe. The drain must withstand boiling water.

WARNING:

DO NOT CONNECT T HE DRAIN DIRECTLY T O A BUILDING DRAIN.

There must be a free air gap between the end of the hose and the building drain. The free air gap should be as close as possible to the unit’s drain. There must also be no other elbows or othe r res trictions between the unit drain and the two inch free air gap.

IMPORTANT: Do not allow any water traps in the line. A trap can cause pressure to build up inside the cavity during steaming, which will make the door gasket leak.

NOT E: Improper drain connection will void the warranty.

b. CC10-E With Drain Tank

A 1½ inch (4 cm) ID hose may be attached to the supplied drain elbow with a clamp. The hose may be connected directly to a building drain since the drain tank has an air vent, which eliminates the need for a free air gap at the building drain. Do not block the air vent in any way. Do not attach anything to the vent tube or reduce its size.

Do NOT use plastic pipe in the drain line, because the drain must withstand boiling water.

If your CC10-E is equipped with the optional split water supply, the supply for each steam generator must be able to fill the generator with 1½ gallons (5.7 liters) or water in 1½ minutes. The make-up water rate is 0.06 gallons per minute (0.2 liters per minute). Condensate spray water rate is 0.34 gallons per minute (1.3 liters per minute) at 30 PSI (210 kPa).
