2.0 INSTALLATION INSTRUCTIONS

GENERAL

The 5$-4 steamer is a single compartment electric pressureless steam cookers with an

internal electric steam generator that maintains water temperature at approximately 205°F. For
voltages 208, 240 and 480 it is rated at 10 kW. For voltages 220 and 380 it is rated at 8.4 kW.

At high altitude locations a lower temperature is required to achieve atmospheric steaming.
Contact your authorized service office to have the thermostat adjusted if the steamer will be
operated at high altitudes.

INSTALLATION

UNPACKING

Immediately after unpacking the steamer, check for possible shipping damage. If the steamer
is found to be damaged, save the packaging material and contact the carrier within 15 days of
delivery.

Prior to installation, verify that the electrical service agrees with the specifications on the
machine data plate which is located on the left side panel.

LOCATION

Allow space for plumbing and electrical connections. Allow adequate access for operating and
servicing the steamer (36" at the front of the steamer and 15" above the steamer).

LEGS (OPTIONAL)

If the optional 4" adjustable legs are used, remove the four levelling feet on the bottom of the
steamer.

LEVELLING FEET (Standard) OR 4" ADJUSTABLE LEGS (Optional)

Thread the four 2" levelling feet shipped in a bag inside the steamer cabinet into the threaded
holes on the bottom corners of the steamer. Or, thread the four optional 4" adjustable legs into
the threaded holes on the bottom corners of the steamer.

LEVELLING

Using a spirit level or pan of water in the bottom of the steamer, adjust the levelling feet or the
feet on the adjustable legs to level the steamer front-to-back and side-to-side. After the drain is
connected, check for level by pouring water onto the floor of the compartment. All water should
drain through the opening at the back of the compartment cavity.

ANCHORING STEAMER (Without Legs)

1. Place steamer in the desired location on the levelled counter top and mark four corners.
Remove the steamer and drill ½" holes as indicated in Figure 1.

2. Apply a bead of RTV or other equivalent sealant around bottom perimeter edge of the
steamer. If anchoring the steamer, this bottom seal is necessary to meet NSF
requirements.

3. Set steamer on counter and bolt down securely with 3/8 - 16 bolts (not supplied).

STACKING KIT

Follow instructions in the stacking kit when installing stacked convection steamers.

PLUMBING CONNECTIONS

WARNING: Plumbing connections must comply with applicable
sanitary, safety and plumbing codes.

Connect the water supply lines to the 3/8" NPT (internal thread) copper tube inlet. The water
lines supply water to the generator tank and the cooling system where steam is condensed
before entering the drain line. Each will be marked to indicate condensate or boiler feed. The
condensate feed must be cold water and the boiler feed may be either cold or hot water.
Providing hot water feed to the generator will reduce recovery time during cooking. A manual
shutoff valve must be provided convenient to the steamer.

DRAIN CONNECTIONS (FIGURE 2)

The drain connection (Fig. 2) must be 1" IPS down, preferably with one elbow only, maximum
length of 2 feet before open air gap and piped to an open air gap type drain. Drain pipe should
be copper. DO NOT use PVC pipe - PVC pipe may lose its rigidity or glue may fail.

FIGURE 2

CAUTION: In order to avoid any back pressure in the steamer, do
not connect solidly to any drain connection.

WATER QUALITY

The water supply connected to this steamer should contain no more than 2.0 grains of
hardness per gallon with pH from 7.0 to 8.5. This degree of hardness and pH can easily be
obtained with the use of a properly maintained water softener.

Water supplies vary from one location to another. A local water treatment specialist should be
consulted before installing any steam generating equipment.

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 surfaces of the heating devices become coated with scale, reducing the heat transfer
efficiency. This can produce hot spots on the heating elements 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 cell. Once this
scale becomes wet, the water level control is unable to maintain the proper water level in
the boiler. This situation may cause an electric heating element to fail if the element is not
adequately covered by water.

Strainers and filters will NOT remove minerals from the water.

Refer to REMOVAL OF LIME SCALE DEPOSITS, page 20.

VENT HOOD

Some local codes may require the steamer to be located under an exhaust hood. Information
on the construction and installation of ventilating hoods may be obtained from Vapor Removal
from Cooking Equipment, NFPA standard No. 96 (latest edition).

ELECTRICAL CONNECTIONS

WARNING: Disconnect electrical power supply and place a tag at
the disconnect switch to indicate that you are working on the circuit.

Electrical grounding must be provided in accordance with local codes or in the absence of local
codes, with the National Electrical Code, ANSI/NFPA70, or the Canadian Electrical Code, CSA
C22-2, as applicable.

Use copper wire suitable for at least 90 degrees Celsius. The steamer must be grounded. The
wiring diagram is located on the right side panel as you face the steamer.
