known health department and sanitation codes and be
NSF listed.
Controls
Unit shall have all solid state controls to include digital
timer with LED readout, power on/off and mode selection
touch pad switches and knob set temperature control
with continuous LED digital readout. Temperature can be
displayed in either F or C. If the “Cook Probe Hold” option
is ordered a low range solid state temperature control with
continuous LED readout provided. If Programmable option
is ordered up to 50 recipes can be entered and used
for cooking. The “Cook Hold Probe” and Programmable
options provide a temperature probe to allow cooking to
a selected core temperature. Hidden door interlock switch
cuts power to fan and oven/steamer elements when door
is opened. Wait, Ready and Hot indicator lights provide
status in each cooking mode. Clean and Service lights
indicate when the unit needs attention. Solid state circuit
has self diagnostic program and pre-programmed clean
cycle to assist in trouble shooting and daily cleaning.
Performance Features
On switch activates power to circuitry. When Oven Mode
is selected, electric elements surrounding special side
mounted forced air blower activate; to provide oven
temperatures up to 575°F rated maximum. When Steam
Mode is selected, cavity accessible steam generator fills
with water and elements are activated; to generate pressureless steam at 212°F. When Combo Mode is selected,
oven elements and steam generator provides controlled
continuous super heated steam.
Special blower provides high speed forced convection
within cooking chamber in all cooking modes. Cavity is
designed for more even heat and steam distribution.
Self Contained Steam Source
Two replaceable heating elements generate steam in each
easy access steam generator. All condensate exits through
cavity drain. Safety or low water cutoff provided and generator automatically drains when unit is turned off.
Pan Capacity
Pan Size/Type Number
18 x 26” Bake Pans 18
12 x 20 x 2 1/2” Steamer Pans 20
Installation
Specify 208, 240 or 480 Volt, 3 phase, 60 cycle electrical
service for each cavity. Each cavity requires dual cold water
supply lines (3/4” D hose connection). Single free venting
drain (2” hose connection) required.
Water Quality
All steam systems are subject to contamination and failure
due to mineral content found in all water supplies. To
minimize service problems, a Groen PureSteem Water
Treatment System is recommended.
Recommended MINIMUM water quality standards are: Total
dissolved solids (TDS) content should have a value of 3040 parts per million, and the water pH should be 7.0-9.0.
Note: Because of the Combo’s cavity accessible generator,
frequent visual inspection of elements is simplified and
recommended.
