1. Beforeconnectingthevalvetoinletandoutletpipes,makesurethatthereisnodirtintubesandcouplingofthevalve.
2. Beforefirstuseofthevalve,checkitanditsfunctionfollowingnextsteps:
‐ Connectthevalvewithasuitablesupplypressure.Neverexceedthemaximumpressureallowed.
‐ Check the working of the valve (outlet couplers or plugs must be properly closed). Move the handle backward (filling) to let the
compressedairgothroughthevalvetotheoutletcoupler.
‐ Movethehandleforwardtostoppressuresupply.Youcanreadthepressureonthegauge.
‐ Toreleasethecompressedairfromthevalve,unscrewtheknurlingnutonthereleasevalveuntilthereadinginthegaugeis0bar.

Amaximumof2cushionscanbestacked.Toperformtheraisingoperation,thelowercushion,whichisusedasabase,mustbefullyinflated
first,andthentheuppercushionshouldbeinflatedcarefully.Neverstartinflatingtheuppercushionifthelowercushionisdeflated.
To deflate the cushions, make the process in reverse order: first deflate the upper cushion before start deflating the upper cushion. Never
deflatethelowercushionbeforeoratthesametimethanuppercushion.
4.MAINTENANCE

After each use, clean the cushion using slightly soapy water without detergent, rinse and dry the cushion. Then, check the integrity of the
externalsurfaceandanyexcessivedeformation(creases,bubbles,cuts).Incaseofdoubt,donotusetheproductandcontactLARZEP.

Beforeanyintervention(changespareparts),makesurethatthevalveorsystemisnotunderpressure.
PROBLEMS DAMAGES SOLUTION
‐Itdoesnotmaintaintheload. ‐ Dirt in the air connection, that finishes
stagnatinginthecheckvalve.
‐ Make sure that the hose; or the device to
connectthey,arecleaned.
‐Thecushiondoesnotloosepressure. ‐ The air does not return because the filter of
thesilencerisdirty.
‐ Unscrew the silencer and clean/replace
filter.
‐Thecushiondoesnotinflatecompletely. ‐Theinletairpressureofthecushionissmaller

‐Verifytheworkingpressure,itmustbe8bar.
