Unified Brands HYPERSTEAM (2)HY-5G - Manual (Page 9)

OM-HY-5G

Initial Start-Up
After the HY-5G Steamer has been installed, test it
to ensure that the unit is operating correctly.
1. Remove all literature and packing materials
from the interior and exterior of the unit.
2. Make sure the water supply line is open.
3. Make sure that the gas supply line is open
and that the manual knob on the main gas
valve is turned to the “on” position. This
valve is located behind the front access
panel on the right side of the unit.
4. Turn on electrical service to the unit. The
HY-5G will not operate without electrical
power. Do not attempt to operate the unit
during a power failure.
5. The steamer will not operate until the pilot
burner has been ignited. To light the pilot
burner, activate the pilot switch located
behind the sliding door located on the right
cover panel. When the pilot ignition
sequence has been successfully completed,
a green light - on the pilot switch will glow.
6. The “trial for ignition” period is roughly 90
seconds. If the pilot burner does not light
within about 90 seconds after the switch is
activated, the ignition system automatically
stops gas flow to the pilot burner and stops
the ignition trial. If this happens, turn off the
pilot switch and repeat the trial for ignition.
During the initial start-up, the pilot may
require several trials for ignition until all the
air is bled from the gas piping. Subsequent
start-ups should require only about 5
seconds to achieve pilot ignition.
NOTE: See Automatic Operation of Pilot at
the end of this section.
7. Once the pilot burner flame has been
established (the green light on the pilot
switch is on), press the “ON” switch for the
desired steamer cavity. The steam
generator will fill with water.
NOTE: The door MUST be closed for the
main (high) burner to work.
8. When the steam generator has filled with
water, the low and main burners will ignite
automatically. Within 8-10 minutes the
READY light will come on, indicating that the
water has reached its standby temperature.
When the READY light is displayed, you
may take any one of the following steps:
a. Set the timer to the desired time for
timed steaming.
b. Turn the timer knob to the manual ON
position for continuous steam.
c. Let the unit stay at standby temperature.
WARNING
WHEN YOU OPEN THE DOOR, STAY AWAY
FROM STEAM COMING OUT OF THE UNIT. THE
STEAM CAN CAUSE BURNS.
9. To shut down the unit, press the ON switch
into the off position. The steam generator will
then drain. You may also switch off the pilot
switch to conserve energy.
10. If the HY-5G Steamer behaves as described,
the unit is functioning correctly and ready for
use.
Automatic Operation of Pilot
Once the pilot burner is lit, it essentially functions as
a standing pilot. In this state, if the pilot is
accidentally extinguished (by a very strong gust of
wind for example), it will re-ignite automatically. The
unit will completely shut down for a few seconds
while the pilot is re-ignited. Then the unit will come
back on and resume operation in the mode and with
the (running) timer value existing just prior to
shutdown. The pilot switch may be turned off during
“off hours” to conserve energy.
After the unit has been running, if the pilot burner
ever fails to re-ignite automatically within 90
seconds, wait 5 minutes before you attempt to
reactivate it. In the unlikely event that ignition
problems persist, contact your authorized Groen
Service Agency.
NOTE: For operation at high altitudes (2000 feet and
above) please consult the Groen Food Service
Engineering Department.
