MANIFOLD ASSEMBLY
 DANGER
Topreventelectricalshock,ALWAYSdisconnectconcentratorfromelectricaloutlet
beforeservicing.
CAUTION
Thisisamaintenancefreevalve.Openingthevalvewillvoidanyandallwarranties
applicabletothevalve.
Replacing 4-Way Valve and/or Manifold Assembly
NOTE:Forthisprocedure,refertoFIGURE 20.1onpage 67.
1. Unplugunit.
2. Removecabinet.RefertoRemovingCabinetonpage 23.
3. Cuttheonetiewrapthatsecuresthemanifoldexhausttubetothe“F”tube.
4. Removethemanifoldexhausttubefromthe“F”tube.
5. Cutthetwotiewrapsthatsecurethe“F”tubetothe4wayvalve/manifoldassembly.
6. Removethe“F”tubefromthe4wayvalve/manifoldassembly.
7. Usingahoseclamptool,removetheclampsthatsecurethevinyltubestothe4‐way
valve/manifoldassembly.
8. Removethevinyltubesfrombothsidesofthe4wayvalve/manifoldassembly.
9. Notetheorientationofthe4‐wayvalve/manifoldassemblybeforeremovingfor
correctre‐installation.
10. Lift4‐wayvalve/manifoldassemblyup
andoutofthebaseoftheconcentrator.
11. Disconnectspadeconnectorslocatedonthesideofthe4‐wayvalveassembly(Not
shown).
12. Removethefourmountingscrewsthatsecurethe4‐wayvalve/manifoldassembly
together(Detail“A”).
13. Replacethenecessarycomponent(s).(i.e.‐4‐wayvalve,manifoldorboth).
14. Looselyinstall
mountingscrewsthrough4‐wayvalveandintomanifoldassembly.
NOTE:Ensurethemanifoldgasketisinplaceon4‐wayvalvebeforeinstalling.
