Introduction
PRODUCT DESCRIPTION
Congratulations on purchasing the Market Forge Sirius II.
The Sirius II is a single compartment countertop or two-
compartment oor model steamer featuring pressureless
steam cooking, a circulating fan inside the cooking cham-
ber to speed cooking and an automatic preheated waterll
mechanism. Sirius II also features a clean water reservoir
system. The cooking chamber of the SIRIUS II is treated
with a scratch resistant, non-stick surface. A drain from
the rear of the steamer is provided for easy safe draining.
The Sirius II steamer has a burner ring rate of 27,000
BTU/hr at a pressure of 3.5” W.C. for natural gas and 9”
W.C. for propane gas.
CAUTION
Do not use utensils, steel wool, or other harsh
abrasives to clean your steamer. Scratching of
the non-stick surface and stainless steel casing may occur.
SAFETY FEATURES
As with any cooking process, or with any piece of com-
mercial cooking equipment, there are potential hazards
to both the operator and the piece of equipment if care is
not taken. In designing the Sirius II steamer, safety features have been built in to protect against many of these
potential hazards, but TRAINING OF EACH OPERATOR
AND CAREFUL ADHERENCE TO ALL WARNINGS ARE
NECESSARY TO ENSURE THE SAFETY OF USERS.
Diagnostic sensor shut-off: The thermostat controller
has a built in diagnostic feature that will automatically shut
down the burner if the sensor probe fails, which will avoid
overheating.
High Limit shutoff: If the steamer runs dry the burner will
shut down.
Overow: An overow standpipe incorporated into the
reservoir drain allows water to ow out the back drain of
the steamer in case of a waterll malfunction.
High water sensor: Two water level sensors are located
on the lower backside of the steamer. The lower sensor
activates the waterll mechanism. The upper sensor will
shut off water ow if an overow situation occurs. It is im-
portant that both sensors are kept clean so that the stainless part is shiny.
WARNING
Failure to keep both water level sensors clean
may result in hot water owing out the overow or the front door of the steamer.
Door open safety switch: There is a safety switch built
into the door frame that shuts down the burner, fan and
lights when the door is opened. Once the door is closed,
all functions return. THE DOOR MUST BE FIRMLY
CLOSED IN ORDER FOR THE STEAMER TO FUNCTION. IF STEAM IS ESCAPING, DOOR IS NOT PROPERLY SHUT AND MAY AFFECT COOK TIMES, PRODUCT QUALITY AND WATER CONSUMPTION.
Time delay relay: The steamer has two timers built into
the electrical system to shut down should the water level
system fail. When the steamer is rst turned on and the
reservoir is empty two countdown timers will begin to
count. If it takes longer than 60 seconds for the level of
the water to come into contact with the lower water sensor probe, the burner and the heating light will turn off.
After the water comes in contact with the lower probe the
burner and heating light will come back on.
Ignition control: In the event of ame failure, the ignition
control will lock out. It can be reset by turning the steamer
off. Wait 5 minutes and turn on again.
WARNING
Failure to shut the steamer door adequately
can cause the door to pop open when in op-
eration. Close door rmly.
CAUTION
Failure to keep the overow outlets clear and
unobstructed may result in hot water owing
out the door of the steamer. A blocked over-
ow and drain could allow water to ow to the
countertop or oor, which can cause slippery
conditions. Modifying the steamer to operate
without the overow standpipe could cause
dangerous situations and will void the warranty.
