Operating sequence
Ensure that the water and electric isolation valves are open before attempting to
operate the appliance. The tank will automatically fill with water to the correct level.
NEVER OPERATE WHEN TANK IS EMPTY.

Check water level is between the indicator marks (Fig 4 - A).
Fig 4
Press the On/Off switch to the ‘On’ position, both switch and amber neon will
illuminate. All three heating elements will now be operational.
When the amber neon extinguishes, the appliance has reached cooking
temperature. The rear element alone will continue to operate to maintain this
temperature.

IS 469 ECN 3607 Page 8 of 15
When operating, do not open the door when the steamer is hot. First slacken off the
handle and allow steam to vent around the door opening. Wait 15-20 seconds
before slowly opening the door fully. This precaution prevents a sudden discharge
of steam into the operators face. Always open the door slowly in 2 stages.
Note: This appliance is protected by a safety thermostat which will cut out the
power in the event of a fault. Should the safety thermostat function during normal
use, it may be reset by depressing the red button located in the roof of the lower
cabinet (See Fig 5).

Explanation of the control system
The appliance is fitted with a pre-set control thermostat together with a safety
thermostat. Neither is operator accessible.
When the water and electricity isolating supplies are switched on and the water inlet
tap is open, water is allowed into the reservoir and then into the cooking chamber.
Once the correct water level is reached, the green switch is pressed, the amber
neon illuminates and all 3 elements are energised.
When the appliance reaches temperature, the front 2 elements are switched off and
the amber neon extinguishes. The rear element remains energised to maintain
temperature.
