PREPARATION FOR INSTALLATION

Select and prepare the operating location before permanently positioning the unit. Protect
the unit and packaged components during site preparation. Do not select the operating
location or start installation before checking the electric power, gas, and water quality
requirements to assure proper drainage, ventilation, and safety.

UNPACKING AND INSPECTION

The is packed in a wooden shipping crate. The fat filter is packed in a separate box.
Additional components, not assembled at the factory are packaged inside the Oven/Steamer
cooking Compartment. These are:

Owner’s Manual Flue Diverter (optional)

Wire Shelves Legs (optional)

After disassembling the shipping crate, visually inspect the for damage.
Before unpacking the separate components, inspect their shipping cartons for damage.
If the cartons are not damaged, unpack them and inspect the components for damage or loss.

• If the and its separate components are delivered in good condition, close
and reseal all the component packages. Then proceed to Protecting The Oven/Steamer.

• If any shipping carton appears damaged, refer to the Shipping Damage Instructions below.

• If the or any of the components have suffered shipping damage or loss,
refer to the Shipping Damage Instructions below.

Shipping Damage Instructions

If shipping damage or loss is discovered or suspected, observe the following guidelines in
preparing a shipping damage claim.

• Write down a description of the damage or the reason for suspecting damage as soon as
it is discovered. This will help in filling out the claim forms later.

• As soon as damage is discovered or suspected, notify the carrier that delivered the
shipment.

• Arrange for a carrier representative to examine the damage.

• Fill out all appropriate claim forms and have the examining carrier sign and date each form.

PROTECTING THE OVEN / STEAMER

While running power and supply lines to the operating location, remove the and components
from the immediate work area. To maintain them in good, clean condition and prevent loss
or damage:

1-

Leave the packaged components inside the cooking compartment.

2-

Keep the fat filter and together to prevent loss.
Keep the clean by covering it with a plastic tarp or drop cloth.

3-
4-

Do not store other items on top of the machine.

33

90028771rev00

PROTECTING THE OVEN / STEAMER

Electric Power Requirements

The characteristics of the electric power supply must match the power requirements
specified on the Oven/Steamer product identification plate.
The plate is secured to the outside of the right-side access panel as illustrated in Figure
2-2.Gas Supply Requirements

WARNING

NEVER EXCEED 14”/355.6 mm WATER COLUMN (1/2 psi) GAS PRESSURE.

If the gas supply pressure exceeds 14”/355.6 mm water column, a pressure

regulating valve must be installed in the gas supply plumbing to reduce the gas

pressure to less than 14”/355.6 mm water column.

• Natural gas pressure must be between 4.5”/101.6 mm -14”/355.6 mm water column.

• Propane gas supply pressure must be between 11”/304.8 mm - 14”/355.6 mm water column.

WATER QUALITY REQUIREMENTS

Cold or hot water (max. 122 °F/50 °C) for steam generator and humidifier.

WARNING

Using water not within the limits specified in this manual could void or adversely

affect the warranty coverage of the Oven/Steamer.

As with any steam generating equipment, poor water quality degrades Oven/Steamer
performance. If feed water is low in Total Dissolved Solids (TDS) and free of particulate
matter, the steam generator, heating element, and valves of the Oven/Steamer will give
years of trouble-free service with a minimum of maintenance.

In some areas, even potable tap water contains a variety of impurities that can cause
costly problems in steam generating equipment.
Of primary concern are mineral salts and other impurities which remain behind as lime or
scale deposits during the steam generating process. These deposits have caused many
components to fail, including heating elements, probes, and solenoid valves.
Of equal importance is the decrease in heat transfer efficiency caused by lime and scale
deposits. Decreased heat transfer increases water and power consumption. Use of the
in areas with poor water quality requires installation of a Steamer Gard water treatment
system or increased frequency of maintenance, cleaning, and descaling.

Check the quality of supply water before starting construction of the water supply lines.
If a water treatment system must be installed to achieve acceptable water quality, install
it before connecting the water supply lines to the Oven/Steamer.

34

90028771rev00

WATER QUALITY REQUIREMENTS

Contact a local water treatment specialist for an on-the-premises water analysis.
The recommended minimum feed water quality requirements for the Oven/Steamer are
listed in Table 2-2.

Table 2-2. Minimum Supply Water Quality Requirements

Total Dissolved Solids less than 60 parts per million
Silica less than 13 parts per million
Alkalinity less than 0 parts per million
Chloride less than 30 parts per million
pH factor greater than 7.5

Softened, Treated, or Filtered Water

Do not use softened or chlorinated water in the steam generator.
If the water supply is treated or softened either by the water company or on the
premises, it may contain chlorine or various salts.
These additives are damaging to the steam generator. Salts used to soften water cause
rapid scale buildup, and increased corrosion.

The hardness of the water has to be from 1 ÷ 4 degrees Clark (1 to 6 fH/0.5 and 2.8
dH). Some water treatment plants kill bacteria in the water by adding chlorine.

When heated in the steam generator, chlorinated water rapidly dissolves generator walls
and heater elements. In extreme cases, poisonous and highly corrosive chlorine gas is
released in the steam generator. Installing a high volume water filtering system removes
most of the salts used for water softening. Contact a local water treatment specialist or
the local water company for assistance with chlorinated water.

Always connect an untreated cold water supply to the steam quenching and boiler
rinsing water supply line. DO NOT USE HOT WATER.
The oven/steamer will not function properly or within design safety limits if hot or
warm water is supplied.

35

90028771rev00

WATER SUPPLY SYSTEM

Select a water supply system that fulfills the following elements: the two different
inlet water supplies (softened and untreated) must provide a minimum dynamic
pressure of 35 psi (2.4 kg/cm2) and a maximum static pressure of 60 psi (4.1 kg/
cm2). If the static pressure exceeds 60 psi, a pressure regulator must be installed
in the supply lines. Refer to page 33 for detailed pressure and fitting requirements,
and for the recommended plumbing layouts.

If analysis shows that the supply water is NOT within the required limits, install a
Steamer Gard water treatment system. Figure 2-6 on page 33 illustrates a treated water
supply arrangement.
If analysis shows that the supply water is NOT within the required limits, and it is not
possible to install a Steamer Gard water treatment system, plan on increasing the
frequency of maintenance, cleaning, and descaling beyond that recommended in the
maintenance schedule (Chapter 4).

INSTALL AND CONNECT THE FREE AIR VENTED DRAIN LINES

The drain outlets and the drain vent at the top of the unit and must be free air
vented to equalize the pressure in the with the atmosphere.
Generating steam causes pressure to increase in the unit; cold water flow into the
condenser creates a vacuum (low pressure) in the condenser. Without a free airvent, either
high or low pressure in the compartment will cause malfunction or damage.

• Pressure build up in the steamer will cause steam and hot water leakage around the door.

• A vacuum will implode the steamer and cause permanent physical damage.

Refer to Figure 2-4, and the dimension drawings (Figure 2-2). The drain outlet
discharges exhaust steam and hot condensate from the oven/steamer.
The drain exhaust vents ( and ) and a 1 inch/25 mm minimum clearance between the
drain opening and floor provide the with free air venting.

Furnishing and installing the drain lines and fittings is the responsibility of the owner and/or
installer. Figure 2-4 illustrates a drain layout recommended by the Manufacturer.
The drain line: Use a heat-resistant plastic pipe (not flexible), installed without loops or
kinks and no longer than 2 metres with a slope of no less than 4 degrees, or realize a drain
line with a gravity flow away from the unit. Drain line must not be connected to the drain
lines of any other equipment. In compliance with current standards, the drainage piping
must not be connected in a straight line.
