Unified Brands (2)HY-5G manual OM-HY-5G Initial Start-Up, Automatic Operation of Pilot

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.
