2 SAFETY
2.1 GENERAL WARNINGS
It is important to r ad this manual b for p rforming any op ration on th pump. Complianc with th saf ty
standards of th country in which th pump is install d and r quir m nts of qualifi d p rsonn l for various
maint nanc , us , installation, tc. ar r comm nd d throughout th lif of th pump.
Th main rul s of conduct to b obs rv d for op ration at a suitabl l v l of s curity ar th following:
• Installation, op ration, maint nanc , tc. op rations should always b p rform d by qualifi d, train d p rsonn l.
• Without xc ption, always w ar n c ssary p rsonal prot ctiv quipm nt.
• Always p rform all cl aning, adjustm nt and maint nanc op rations with all pow r quipm nt cut off.
• Do not dir ct wat r j ts toward l ctrical parts, v n if th y ar prot ct d by nclosur s.
• Do not smok during work or maint nanc , sp cially wh r solv nts or flammabl mat rials ar b ing us d.
• Do not damag symbol plaqu s or pictograms on th pump. If th y should accid ntally b com damag d,
imm diat ly r plac th m with oth r id ntification plaqu s.
D.V.P. Vacuum T chnology s.p.a. disclaims any liability for damag to p rsons or prop rty r sulting from improp r
us of th pump, from tamp ring with its saf ty apparatus or failur to obs rv op rational saf ty standards.
2.2 RESIDUAL RISKS
HAZARD
This pump has been designed to minimise residual risks to personnel. We urge you, however, to
take the utmost care and attention in carrying out maintenance operations. The confidence gained
with frequent contact with the pump too often leads users to forget or underestimate risks.
High temperature hazard
Pump surfac s can xc d a t mp ratur of 70°C. Install th pump in a prot ct d ar a that is acc ssibl only by
authoris d p rsonn l and only p rform op rations wh n th pump is stopp d and cool d.
Hazard generated by low pressure
Avoid contact with pump intak attachm nt during op ration. Introduc air into th suction circuit b for any
int rv ntion. Contact with low pr ssur points can caus accid nts.
Hazard generated by pressure
Th pump tank is pr ssuris d. Do not op n and do not l av oil fill r or drain plugs op n during op ration.
Danger from the emission of harmful substances
Pump outl t air contains trac s of oil mist. Ensur compatibility with th working nvironm nt.
Faults or w aring of s als may caus oil lubricant l aks. Avoid disp rsion in soil and pollution of oth r mat rials.
Wh n v r air containing hazardous substanc s ar suck d in (i. . biological or microbiological ag nts), us
abat m nt syst ms plac d b for th vacuum pump. Us d oil must b dispos d of according to applicabl
r gulations in th country of pump us .

Electrical hazard
El ctrical quipm nt in th pump includ s liv parts which, upon contact, can caus s rious damag to p rsons and
prop rty. Any kind of int rv ntion on th l ctrical syst m must b p rform d by qualifi d p rsonn l.
Fire hazard
Us of th pump for any us s not provid d for or prohibit d by this manual as w ll as a lack of prop r maint nanc
can caus malfunction with a risk of ov rh ating and fir .
In cas of fir , do not us wat r to xtinguish th flam s, but us dry ch mical or CO2 or oth r m ans compatibl
with th pr s nc of l ctrical quipm nt and lubricants.
Slip and fall hazards
Th “L” s ri s vacuum pumps us lubricant to op rat . A simpl maint nanc or improp r us not complying with
th instructions includ d in this manual can damag th gask ts and/or s als and caus th lubricant to spill on th
floor constituting slip and/or fall hazards for p rsonn l.
Entanglement hazard
Th r is a p rman nt imp nding hazard of ntangling or ntrapping hair and clothing in th cool r fan insid th
guard n ar th fan casing on th l ctric motor. Ti long hair up and do not w ar baggy clothing, long lac s or oth r
it ms that could g t caught up.
Part projection hazard
Install th pump in ord r to avoid thos in charg of works b ing dir ctly hit by parts or bits of parts flying through
th fan cov r casing du to th cooling fan br aking.
2.3 PICTOGRAMS
Pictographs with th warning symbols and saf ty symbols for op rators hav b n appli d to th pump. R ad
car fully and tak not of th symbols and th ir m ssag s b for using th pump.
ELECTRICAL HAZARD
The pump is near electrical connections (protected) but where accidental contact can cause
electric shock and death.
HOT SURFACE HAZARD
The pump is close to surfaces with temperatures exceeding 70°C which may lead to burns of
medium severity.
REFER TO INSTRUCTION MANUAL/ OOKLET
efore use read the instructions in the operating manual.

3 PUMP DESCRIPTION
3.1 INTENTED USE AND CONTRAINDICATIONS
3.1.1 INTENTED USE
Th pumps d scrib d in this manual ar oil r circulating rotary van pumps. Th s vacuum pumps hav b n
sp cifically d sign d to work with cl an air, in rt gas or small amounts of wat r vapour, having a t mp ratur
b tw n 12 and 40 °C at th intak .
Th s pumps ar suitabl to vacuat small clos d v ss ls or, in cas of som mod ls, to work continuously at
sp cific final pr ssur , as xplain d in paragraph 3.3 “Dim nsions and charact ristics “.
Any oth r us is prohibit d. Th Manufactur r is not liabl for any damag to p rsons and/or prop rty caus d by
improp r us or not allow d us of th pump.
3.1.2 CONTRAINDICATIONS
Any use other than that for which the pump was constructed is to be considered an
abnormal condition and therefore can cause damage to the pump and pose a serious
danger to the operator.
B low is a s ri s of op rations involving improp r us of th pump, which ar not p rmitt d und r any
circumstanc s.
• Do not us th pump in an xplosiv or aggr ssiv atmosph r or in an atmosph r with a high conc ntration of
dust or oily substanc s in th air and do not us th pump to pump xplosiv , flammabl or corrosiv gas s or
gas that form particl s. Using th pump in th s atmosph r s and with th s typ s of gas s can caus injury,
xplosion, fir or s rious damag to th pump.
• Do not us non-original spar parts or parts not provid d by th manufactur r.
• Do not us th unit to pump solid mat rials, ch micals, powd rs, solv nts or oth r substanc s diff ring from
thos p rmitt d Th s typ s of mat rials may damag th unit, d grad its p rformanc or r duc its lif .
• do not xpos th pump to rain, st am or xc ssiv humidity.
• Do not plac or stor n ar in th proximity of flammabl or combustibl mat rials or substanc s.
• Do not us th pump as a compr ssor.
3.2 FKM VERSION
This v rsion of th pump is quipp d with sp cial t chnical d vic s, such FKM s als that allow for us v n in th
pr s nc of som aggr ssiv gas s.
WARNING
Contact the seller to make sure that the pump is suitable for use with a given aggressive gas.
