2.0 INTRODUCTION
DESCRIPTION

The model SBF-3E steamer comes equipped with a standard 9.0 kW heating block that can be
reduced to 6 kW on single phase supplies. Model SBF-5E steamer comes equipped with a
standard 15.0 kW heating block that can be reduced to 10 kW on single phase supplies.

Your new steamer has been designed and manufactured to meet the toughest industry
standards. The best possible workmanship and materials along with laboratory tests have been
utilized in its design.

Proper installation, care and maintenance will give you years of reliable, trouble free operation.
The SBF-3E and SBF-5E are electric fired pressureless steam cookers. The cooking

compartments are equipped with a three-piece door with inner gasket plate isolated from the
exterior surface. Door latch operates by slam action for positive sealing of the door. Operating
controls are displayed on a front-mounted panel and include indicator lights for ready and
cooking modes, a timer to set cook times and an illuminated rocker mode selection switch for
TIMED COOKING, OFF and CONSTANT STEAM.

BASIC FUNCTIONING
The cooker is ready for operation when the READY light comes on.
At the end of the set interval, timer contacts switch to shut off the cooking operation and sounds

a signal buzzer and will maintain a safe food holding temperature at or above 150ΕF. The
buzzer is silenced by returning the timer dial to the OFF position. The READY light will be
illuminated.

within 15 days of delivery. File a claim regardless of extent of damage.

We cannot assume responsibility for damage or loss incurred in transit.
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.
LOCATING
Allow space for vent and electrical connection. Minimum clearances for proper air circulation is

2" on the sides and 6" on the back. Allow adequate access for servicing.

LEVELING

Using a spirit level, adjust the feet to level the unit, front to back and side to side. The unit must
be level for proper operation. Warranty will be void for improper installation.

ELECTRICAL CONNECTIONS

WARNING: The unit must be electrically grounded and comply with
local codes, or in the absence of local codes with the national
electrical code ANSI/NFPA to latest edition. Canadian installation

3.0 INSTALLATION (Continued)

PLUMBING CONNECTIONS

No plumbing connections are required as steamer is filled manually.

DRAIN CONNECTIONS
No drain connection is required.
WATER CONDITION
For best results, Blodgett recommends that the water supply meet the following specification:
Hardness: Less than 2 grains or 35 ppm.

Total Dissolved Solids (TDS): Less than 60 ppm.
PH Factor: 7.0 to 7.5

This degree of hardness can easily be obtained with the use of a properly maintained water
softener.

VENT HOOD
Some local codes may require the steamer to be located under an exhaust hood. It is

recommended that this steamer be located under an exhaust hood to remove excess steam
during cooking operations.

Information on the construction and installation of ventilating hood may be obtained from the
standard for “Vapor Removal for Cooking Equipment”, NFPA No. 96 (Latest Edition).

WARNING: For an appliance equipped with casters, the installation
shall be made with an adequate flexible electrical conduit; adequate
means must be provided to limit the movement of the appliance
without depending on or transmitting stress to the electrical conduit.
The location where restraining means may be attached is to the rear

Once the steamer has been installed, thoroughly test the steamer before operation.

1. Check that door opens and closes for proper operation.

2. Inspect the door gasket to ensure there is no damage.

3. Check without water in the steamer and with “CONTINUOUS” cooking mode selected, that

the “LOW WATER” indicator and alarm comes on within 10 minutes of a cold start.

4. Open compartment door and pour in water up to the “Water Level” mark located at back of

compartment.

5. Select TIMED COOKING mode with the power switch and set the timer to the OFF position.

6. Close door and wait approximately 10 minutes for the READY indicator to illuminate which

will indicate the unit is up to proper operating temperature.
