Congratulations on the purchase of your new
Rosko electric hot steam table.
Afin de maximiser l’usage et la durabilité de votre appareil, nous recommandons de suivre les instructions
se trouvant dans ce guide. Les procédures d’installation, d’opération et d’entretien doivent être respectées afin que
la protection offerte par la garantie s’applique.
2.1. CLEARANCE
It is essential to observe the following minimum clearance when planning the installation of the unit and during
the installation:
•Construction with combustible materials
◽1’’ (25 mm) at the back and on each side of the unit.
•Construction with non-combustible materials
◽0’’ (0 mm) at the back and on each side of the unit.
•Provide adequate space for the unit operation and maintenance.
2.2. RECEPTION AND INSPECTION
This unit has been inspected and verified before shipment. Upon receipt, check immediately for damage
with the delivery person present. If necessary, make your claim immediately.
The warranty is limited to the replacement of defective parts under normal use. No claims will be accepted
for breakage resulting from improper installation, improper operation, or unauthorized service before installation.
Before installation, make sure the specifications of the electric hot steam table match the type of gas supply.
Refer to the nameplate on the side of the unit.
Important: Make sure you have the included components supplied with the hot steam table when you receive it.
All Electric Floor Hot Food Table Models
Materials included:
•1 to 4 separator(s) (the number varies depending on the model)
•1 instruction guide

5RO-STFE_GUIDE (04/22)
2.3. LEVEL
CAUTIONS
Once the unit is in its final position, level the hot food table by adjusting the feet. Make sure the table is level
in the front-to-back and side-to-side axis. It is recommended to level the unit each time it is moved. Proper leveling
prevents accidents and ensures optimal cooking performance.
NOTE: Always handle the unit with someone else helping. Attempting to do so alone may result in injury.
CAUTIONS
In the case of a mobile installation on casters, the installation must meet the following standard requirements,
where applicable:
•In the United States, ANSI Z21.69 Mobile Gas Appliance Connector Standard
and ANSI Z21.41 Quick Disconnect Standard
•In Canada, CSA 6.16 Mobile Gas Appliance Connector Standard
and CSA 6.9 Quick Disconnect Standard
2.4. ATTACHMENT
CAUTIONS
The unit must be installed with restraints to counteract possible stress on the electrical connection.
Do not use the connector or power supply wire to restrict the unit movement. Fixing can be done by inserting
the hot steam table into a battery of equipment or by fixing the table to the back wall with a ring and a chain shorter
than the electrical wire supply.
NOTE: The fastening material is not included.
CAUTIONS
If the fastener needs to be removed, first turn off the hot steam table electric supply.

6RO-STFE_GUIDE (04/22)
2.5. ELECTRICAL CONNECTION
The wire entry for the connection is a ½” knockout hole located on the electrical junction box on the right side
of the unit. Use a ⁄” commercial electrical connector (not included) to insert the electric wire supply into the junction
box. The connection must be done by a certified technician or electrician.
NOTE: The wire connectors are included.
CAUTIONS
Installation must meet the requirements of the codes below, where applicable.
•State or local codes in the United States, or in the absence of local codes:
The National Electrical Code ANSI/NFPA 70;
•Local codes in Canada, or in the absence of local codes:
Canadian Electrical Code CSA C22.1.
1. Manually remove the ⁄” knockout located on the junction box. (Figure 1)
2. Remove the protective plate from the junction box by unscrewing the two (2) fixing screws. (Figure 2)
3. Install and secure the commercial electrical connector (not included) in the hole provided. (Figure 3)

4. Insert and secure the previously unsheathed wire of the correct length into the connector to join
the unit connecting wires.
CAUTIONS
Use a metal wire that can withstand a temperature of 400 °F (200 °C). The wire gauge must also support
the operational current (A) listed on the unit data sheet.
5. Make the electrical connections and grounding according to the electrical schematics.
NOTE: See figure 6, 7, and 8 for details on electrical connections.
6. Replace the protective plate in its original position by screwing the two (2) fixing screws on the junction box.
2.6. 1.6. WATER CONNECTION
This unit is designed to be connected to the water system (filling), using a 1/4'' connector and to the sewerage
(drainage), using a 1” connector. The water connection must be done by a certified technician or plumber. (Figure 4)
