5.Attach new drain valve to valve bracket. Pull silicone hose through drain valve and loosely install hose clamps over both ends of the hose. Be sure silicone hose is properly aligned and does not have any kinks, bends and/or twists.
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 clamps so that the worm screw may be easily tightened. Using a 7mm nutdriver, tighten both hose clamps. Be careful not to overtighten clamps as it may cut hose.
8.Install and tighten valve mounting
9.Plug valve electrical leads into the wiring harness.
To Test:
Operate steamer and allow steam generator to fill. Check for leaks and observe if drain valve fully closes. Turn off steamer and observe that drain valve opens and the steam generator drains. Install back cover.
10.6Water 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.Using a 7mm nutdriver, loosen the three hose clamps on the water inlet valve.
5.Slide the hose clamps down the hose until needed for reassembly. Loosen and remove the hoses using a gentle rocking motion.
6.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.
7.From the back of the steamer, remove the two
8.Carefully unplug the connectors, one at a time and attach to the new valve.
9.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.
10.
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.
CAUTION: Do not overtighten these clamps as that may damage the valve.
Slide the hose clamps so that they are within 1/8 inch (3 mm) 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.
10.8Drain 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.
