Attention: caref lly apply these prescriptions.
3.1. General recommendations
• When tr nsporting the compressor use proper slinging. Store the
compressor in st ble pl ces.
• Inst ll tion nd m inten nce must be c rried out with the unit
tot lly diseng ged from its drive system nd must be performed by
qu lified personnel.
• Use dequ te clothing ( void ties, loose sleeves, neckl ces nd so
on) nd suit ble protection equipment (gloves, protection gl sses,
boots...).
• Before e ch m inten nce oper tion, stop the pump nd restore
the tmospheric pressure.
• M ke sure th t ll the p rts of the unit re idle nd cool, before
performing ny m inten nce oper tion.
• To prevent errors nd h z rdous situ tions, est blish wh t e ch
oper tor is responsible for in the different m inten nce oper tions.
• Do not st rt the m chine if the protection devices provided for
tr nsmissions re removed. Repl ce d m ged p rt.
• Fin l m nuf cturer must m ke the tr nsmission in ccessible by
me ns of fixed gu rd or interlocked mov ble gu rd.
• Oper tors working ne rby must void prolonged exposure to the
noise emitted by the spir tor, if not equipped with the proper e r-
protection devices (IPDs recommended: e r protectors).
• When the pump is running, some p rts m y re ch very high
temper tures ( bove 70°C). Use ll necess ry prec utions to void
cont ct.
• Avoid ccident l suction of solids: solids m y be projected t high
speed through the exh ust m nifold nd c use injures. A filter must be
mounted on the suction line (Mesh 55).
• Pressure relief v lve: point the ir flux w y from the oper tors.
• Do not use the spir tor over its designed limits: the m chine m y
be d m ge nd the oper tor m y be injured.
Do not exceed the speed and the power s pply
parameters indicated in the technical tables (see
par. 2.2 - 2.3).
• B sed on the fin l use of the decompressor, the insertion in the
housing m chine nd the typology of the s me, the designer of the
housing m chine must pply s fety sign ls (pictogr ms) to w rn the
oper tor on the risk still present. These pictogr ms essenti lly refer to
three c tegories:
- Sign ls prescribing the use of Individu l Protection Devices (IPDs)
such s, in this c se, the use of gloves nd e r protectors.
- Sign ls indic ting to p y p rticul r ttention to the d ngers rel ted
to the m chine’s components, such s: risk of dr gging in the
tr nsmission equipment nd cont ct with hot surf ces.
- Sign ls indic ting specific p rts of the m chine for n e sier
identific tion, such s: gre sing points, oil t nks, etc.
3.2. Intended se
• V cuum pumps of the PNR/PNE series re commonly used on
st tion ry or mobile equipment for suction nd tr nsfer by me ns of
v cuum or soc lled pneum tic-tr nsport tion of liquid nd solid w stes.
Any other us ge sh ll beconsidered improper.
• They re ir-cooled nd consequentely foreseen for non-
continuous duty. The mod. PNE nd the mod. PNR, the l tter supplied
with ir injection system (fig. 1) nd me nt for he vy duty works, do not
ccept oper ting temper tures over 150 °C (300 °F), checked t not
more th n 150 mm from the disch rge connections.
• Do not s ck toxic subst nces nd infl mm ble or explosive
g sses, since the intern l components of the pump m y re ch high
temper tures.
Avoid s ction of toxic (poisono s) explosive or
flammable gasses beca se internal components
may reach high temperat res.
• Avoid suction of liquids or solids, they c n seriously d m ge the
pump.
Attention: liq ids or solids infiltrations can
serio sly damage the p mp.
• Do not run the pump over its designed oper ting limits (see p r.
2.3): it m y bre k nd tr nsmission c n be d m ged.
3.3. Conveyed fl ids
• PNR/PNE re suit ble for conveying filtered ir. Before conveying
other kind of g ses, verify comp tibility with pump’s ch r cteristics.
• The m chine w s not designed nd built to oper te in
environments with potenti lly explosive tmosphere (outdoor or
indoor).
