6. Position the valve over the valve mounting threaded
studs and connect both ends of the hose to the drain
box and steam generator.
7. Position the spring clamps about 3 mm (1/8") from
the end of the hose.
8. Install and tighten valve mounting 10-32 cap nuts.
9. Plug valve electrical leads into the wiring harness.

steam generator drains. Install back cover.
10.6 Water Inlet Valve - Three Way
P/N 090827
1. Turn off power to the steamer. Turn off the water
supply to the steamer. Remove the water supply
hose connection on the rear of the steamer.
2. As viewed from the rear, remove the back panel and
the right panel.
3. The water inlet of the valve branches to three
individual solenoid activated valves within a single
housing, with the following sets of wires:
Solenoid Wires
Top Steam Generator Fill: Green and Blue
Bottom Steam Generator Fill: Violet and Gray
Condensate Spray: Black and White
4. Slide the hose clamps down the hose until needed
for reassembly. Loosen and remove the hoses using
a gentle rocking motion.
5. From the back of the steamer, remove the two
screws holding the valve assembly in place. Then
lower the valve WITH THE WIRES STILL
ATTACHED.
6. From the back of the steamer, remove the two 8-32
screws holding the valve assembly in place. Lower
the valve.
7. Carefully unplug the connectors, one at a time and
attach to the new valve.
8. To install a new valve, reverse the procedures and
first install the six wires (three sets) as listed in Item 3
of this Section. Fasten the valve to the steamer with
the two screws. Make sure that the valve is NOT
installed upside down.
9. Re-attach the hoses to the valve. Slide the hoses all
the way so that the end of the hose is flush against
the face of the valve.
IMPORTANT. Make sure that the correct steam
generator hose is connected to the corresponding valve
outlet. Slide the hose clamps back into position around
the end of the hose and tighten the clamps.
Slide the hose clamps so that they are within 3 mm (1/8
inch) from the end of the hose.
TOP hose — to the TOP Steam Generator
MIDDLE hose — to the BOTTOM Steam Generator
BOTTOM hose — to the DRAIN Box
11. Attach the three sets of wires to the valve making
sure that the proper wires are connected to the
corresponding terminals.
To Test:
With power ON, turn on the power switch to one cavity.
The fill solenoid for that steam generator should energize
allowing water to enter the steam generator. When
READY light is ON, spray valve solenoid should energize
and water should enter the drain box.
10.7 Water Inlet Valve Coil
If a solenoid coil on the water inlet valve is defective,
replace the entire valve in accordance with Section 10.6.
10.8 Drain Box Spray Nozzle
P/N 081670
1. Raise the stainless steel vent pipe to remove it from
the drain box. Do not loosen the hose clamp around
the vent pipe. The hose clamp serves to prevent the
pipe from going too far into the drain box. Secure the
vent pipe in the raised position.
2. Lift the cover of the drain box. There are no fasteners
holding the cover on the drain box.
3. Tip the cover and note there is a circular hole in the
middle and the spray nozzle (with a hex head) is in
the center of the hole.
4. With a socket wrench, turn the spray nozzle in the
counter-clockwise direction to remove.
5. To install new nozzle, place pipe compound on the
nozzle threads, insert nozzle in socket wrench and
start the nozzle in the hole. Tighten nozzle.
