WATER QUALITY
Before connecting the steamer to water, the water supply should be analyzed to make sure
specifications are met.
If the water supply fails to meet these specifications, it will be necessary to install a water conditioner
on the boiler cold water supply line. APPLIANCE FAILURE CAUSED BY INADEQUATE WATER
QUALITY IS NOT COVERED UNDER WARRANTY.
Water supplies vary from one location to another. A local water treatment specialist should be
consulted before installing any boiler or water conditioner.
Untreated water contains scale producing minerals which can precipitate onto the surfaces in the
boiler. Due to the temperatures in the boiler, the minerals can bake onto the surfaces and components.
This can result in early component failure and reduced product life.
Mineral scale on components causes several problems:
1. The surface of the boiler becomes coated with scale, reducing the heat transfer efficiency. This can
produce hot spots on the boiler and result in premature failure.
2. The water level probes become coated with scale. Scale will bridge across the probe insulator from
the metal extension which senses the water level in the boiler. Once this scale becomes wet, the
water level control is unable to maintain the proper water level in the boiler. This situation may
cause the boiler to fail if the boiler is not adequately covered by water.
Strainers or filters will NOT remove minerals from the water.
Sensors in the boiler use ions in the water to detect the water level. Do not use distilled (fully
demineralized or de-ionized) water. This could provide a false reading.
START-UP TEST RUN
Refer to the OPERATION section, pages 10 – 13 for more information.
WARNING: THE STEAMER AND ITS PARTS ARE HOT. USE CARE WHEN OPERATING,
CLEANING, OR SERVICING THE STEAMER.
WARNING: THE COOKING COMPARTMENTS CONTAIN LIVE STEAM. STAY CLEAR WHILE
OPENING EACH DOOR.
After the steamer is installed and proper service connections have been made, thoroughly test the
steamer before operation.
1. Turn knob of gas valve counterclockwise to on.
2. Be sure the water inlet valve is open. Close only for service or long shutdown.
3. Locate the power switch and press [ I ] to start. Two indicator lights (Low Water and High Pressure)
become lit as water fills the boiler. After about 4 – 5 minutes, the water will reach the required level
in the boiler and the green indicator light on the reset switch is lit.
