SM-GSSP BOILERLESS STEAMER

ASSEMBLY / DISASSEMBLY

WARNING: AFTER SERVICING GAS PIPING ON GAS MODELS, CHECK FOR GAS LEAKS

BEFORE PUTTING UNIT BACK IN SERVICE.

WARNING: DISCONNECT THE STEAMER FROM ELECTRIC POWER BEFORE BEGINNING

ANY SERVICE PROCEDURES.

GENERAL INFORMATION

This section provides common removal and installation procedures for parts.
The following procedures are based upon having access to the steamer on all
four sides. If the steamer is installed between other appliances and there is not
enough room on the sides for access, the steamer must be pulled out from its
position to gain proper access.
Care should be taken in moving the steamer so as not to stress or pull on the
electrical, gas and water connections.

CAVITY COMPARTMENT SIDE PANELS

For part number, see section on the steamer model parts list.

REMOVAL

1. With a Phillips screw driver remove the two 10-32 screws on the lower

edge of the panel and one at the top edge (at the center of the top panel
overhang). The panel is retained to the steamer by these three screws and
three spring-like clips at the rear edge.

2. Once the screws are removed, the panel can be pulled forward about 1 inch,

then lowered from behind the top panel overhang.

TOP COVER

For part number, see section on the steamer model parts list.

NOTE

: Under normal conditions the top should never have to be removed. The

most likely reason for removing it is if the panel itself has been damaged by a
falling object.
1. Remove right side and left side panels.
2. At the front on each side, remove the #10-32 screw securing the top to the

front panel (see illustration).

STEAMER DISPLAY CONTROL

1. Unplug the display control harness from I/O board.
2. Using Phillips screw driver, carefully remove the four or five screws (number

depends on model) holding the control display enclosure to the front panel.
Carefully make sure harness and USB cable passes through hole in front
panel.

3. Using a Phillips screw driver, remove the four M3 screws and carefully

remove board. Disconnect control harness and USB cable from board.

INSTALLATION

1. Position the board on four studs on control enclosure.
2. Secure the board to control enclosure with four 3M screw and tighten with

Phillips screw driver.

3. Connect harness and USB cable to control board. Install control enclosure

housing while carefully inserting harness and cable through the holes in the
front panel and securing with #10-32 screws.

4. Connect control harness to I/O board.

I/O BOARD

REMOVAL

1. Unplug all connectors.
2. Using a 5/26” socket, remove fout 6/32” lock nuts and remove the board

from four studs on the high voltage panel.

INSTALLATION

1. Position the board on four studs on the high voltage panel.
2. Install 6/32” lock nuts onto the studs and tighten in place using a 5/16”

socket.

3. Insert all jacks in the same connector locations as per removal. Press firmly

to make sure the jack is fully seated on the board.

STEAM RESERVOIR DRAIN VALVE

When the steam reservoir drain valve is de energized or (OPEN) the silicone hose
can freely slide through the valve housing. The steam reservoir drain valve is
located to the right of the steamer cavity.

REMOVAL

1. Turn off power and disconnect steamer from the branch circuit. Remove

right side panel. Let steamer drain completely.

2. Using spring clamp pliers, disconnect ONE END of the silicone drain hose by

loosening the drain hose clamp from the drain fitting coming from the cavity
drain. Remove clamp.

3. Unplug the valve electrical wires.
4. With a 5/16 inch nutdriver, remove the two 10-32 screws holding the drain

valve to the bracket steamer base.

5. Remove the two 10-32 screws and remove the valve from the bracket.
6. Loosen the clamp and remove the other end of the silicone hose from the

drain box. Inspect the hose for any damages or lime buildup. Clean or replace
the hose of required, then reattach to the steam reservoir drain fitting.

INSTALLATION

1. Attach new drain valve to valve bracket. Slide the silicone hose through the

drain valve housing and install hose clamp over the exposed end of the hose.
Check that the hose is straight and not twisted.

2. Fit the exposed end of the silicone hose onto the elbow of the cavity drain.

Using spring clamp pliers, position and tighten the hose clamp.

3. Plug the electrical leads of the valve into the wiring harness. Connect

steamer to branch circuit, and turn on power.

TESTING

drain valve fully closes. Turn off steamer and observe that drain valve opens and
the steam reservoir drains.
1. Reinstall right side panel.
