Equipment Description
Your Groen Combination Oven is a stainless steel cooking chamber consisting of an air heating compartment with fan, a boilerless steam generator, and a control compartment which houses electrical components.
All major components of the Combination Oven are encased in a heavy duty stainless steel cabinet. The cabinet is lined with thick ceramic insulation. A removable drip tray is located beneath the door.
Operator controls are located on the right front of the unit, except for the manual gas shut-off valve, which is on the back left side near the top of the of the unit.
Standard controls let you operate the unit in any one of four cooking modes:
1.As a convection oven
2.As a self-contained pressureless steamer
3.As a combination oven-steamer with low humidity
4.As a combination oven-steamer with high humidity
Cooking chamber size and pan capacities are:
COMBOEASE: 10 steam table pans (12x20x2½”), or 10 full-size (18x26”) bake pans
The unit is available as single, double stack (2 high) units, and low height stand. The optional stand must have casters.
Optional stands are available for single and double stack (2 high) units. The optional stand must have casters. All units are intended to slide under a kitchen hood installed with 78” clearance to floor.
Controls and monitoring displays for cooking times, operating mode and temperature selection are on the control panel. The upper portion of the panel has a text information display. Below it are the touch pads, indicator lights, temperature and time selector knobs and displays, the power ON/OFF switch, and an hour meter to log operating hours.
A digital readout shows the selected temperature, which is entered by turning a knob.
Another digital readout shows the remaining time on an electronic ‘kitchen timer.’ The time is adjusted by turning a dial knob.
2 wash spray nozzles on the rear inside wall of the unit sprays the interior walls as part of the semi-automatic cleaning system.
The air heating space is separated from the cooking
chamber by removable rear and bottom partitions. The compartment which contains the unit’s automatic controls and other electrical components is on
the right side of the unit, and is accessed by removing the right outside panel.
The bottom partition prevents food particles from falling into the water reservoir of the boilerless steamer. Excess water and food particles falling down are collected on
this partition. A water drain is located under the removable bottom partition. Boilerless reservoir water and cleaning water drains from the permanent floor to the stainless steel drain pipe outside the oven. The drain pipe includes a spray condensor which suppresses any steam escaping from the chamber and a drain box.
The unit is provided with two air and steam vents. One is to prevent internal pressure build-up. This vent pipe exit is located at upper left corner of the unit
(just above the rear partition) and is visible from the rear of the unit. The other steam vent is from the drain line on lower rear right and is attached to the water and overflow drain. This allows any steam from the drain water to exhaust above the oven top. Both of these vents must be exhausted above the oven flue and located underneath a kitchen vent hood.

Inspection and Unpacking
Your Combination Oven will be completely assembled in a carton and attached to a skid.
On receipt, inspect the carton and crate carefully for exterior damage.
CAUTION
SHIPPING STRAPS ARE UNDER TENSION 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 nails and sharp pieces of wood or staples which might be left in carton walls.
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.
CAUTION
THIS UNIT IS VERY HEAVY. YOU SHOULD GET HELP AS NEEDED AND USE MATERIAL HANDLING EQUIPMENT TO REMOVE THE UNIT FROM THE SKID AND MOVE IT TO ITS PLACE OF INSTALLATION.
When starting installation, use material handling equipment to lift the unit straight up off the skid. Check packing materials to make sure loose parts are not discarded with the material.

Water Quality and Treatment
It is essential to supply the steam generator with water that will not form scale. Even though the boilerless 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 each day.
Most water supplies contain minerals which form scale. It is this scale which could lead to an early component failure.
Your local 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:
1.The best way to prevent scale is to use a Groen PureSteam™ Water Treatment System which has been specifically designed for Groen steamers and combination ovens. Do not rely on unproven water treatments sold for scale prevention and removal. They are not specifically designed to work with Groen steamers and combination ovens.
2.A well-maintained water treatment system and a regular cartridge replacement schedule is essential.
3.Using a Groen water treatment system will provide longer steam generator/boiler life, higher steam capacity, and reduce maintenance requirements.
4.If you notice a slowdown in steam production, check the unit’s bottom for scale build-up. This could be an indication that the water treatment cartridges need replacing. Heavy scale reduces the unit’s ability to boil water, and can even cause component failure.
MINIMIZE SCALE PROBLEMS BY INSTALLING AND MAINTAINING A GROEN WATER TREATMENT SYSTEM AND BY DELIMING THE STEAM GENERATOR/BOILER REGULARLY.
Groen Combination Ovens features
two separate water inlets — one for the steam generator (for treated water), the other for the
spray condenser (untreated water) and semi automatic wash cycle. The second intake will reduce water treatment requirements resulting in significant savings.
The dual water connections are on the rear of the unit.
caution
a filter suitable for removing ferrite compounds is recommended when the water supply has higher than 50 ppm of iron content. failure to do so could cause rusting of the oven cavity.
Standard water connections for steam generator and drain spray condenser.
