Preface
Destination of use
DPH 35 is a flotation bath an it is compose of a removable tank in glass an a regulate resistance.
The flotation bath has been projecte to optimize the collection proce ures of histological sections obtaine
with the microtome.
The DPH 35 facilitate the sections flotation an isposition in or er to a here perfectly to the sli e.
In this instrument there is the possibility to set up the maximum an minimum level of the set point, the
water temperature, the minimum time in which the relay 1 is off, the relay status in case of anomalies, the
offset an the hysteresis regulation.
This manual escribes DPH35 operation, safety information an maintenance.
The first section eals with “Safety Information”, in which are escribe the a opte symbols, the
instructions an precautions.
The following section “Specifics an Installation” contains all information concerning the installation place
features an mo alities.
In the “Maintenance” section there are information about cleaning perio ic requirements, isinfection an
system controls. The maintenance is very important; for this reason we suggest to rea , un erstan an
follow them carefully.
The users might be a equately traine about its use an they might respect all safety requirements an the
instrument use limits.
The instrument maintenance concerning the electronic parts shoul be performe only by traine an
authorize staff of Diapath S.p.A.
The instrument has been projecte accor ing to the ex D.lgs. 332/00 of 8 September 2000 “ irective
actuation 98/79/CE of 27 October 1998 accor ing to iagnostic in vitro evices irective”.

Quality control
Diapath S.p.A. a optes quality management system ISO 9001(*) an ISO 13485(*) to project, make an
improve the technical-scientific solution for the customer in me ical an iagnostic in vitro systems, assuring
high quality services with the help of an highly qualifie an motivate staff to contribute to the
improvement of Diapath S.p.A. pro ucts.
Diapath S.p.A. constantly looks for customer’s satisfaction, tries to perceive their expectations an to treat
the customer without any iscrimination. Diapath S.p.A. assures the application of normative requirements.
Quality assurance of ata furnishe by Diapath S.p.A. is obtaine through these activities:
•Use only reference material
•Execution of proofs of the whole pro uction
•Correlation of ifferent results
The internal quality control foresees to monitor the most ifficult passages of an analytic process so as to
verify their stability, to assure that quality parameters estimate uring the vali ation or check of the
metho are vali also for real instruments an that they won’t get worse in the course of the time.
Diapath S.p.A. tests its own pro ucts in accor ance with some internal proce ures, to re uce possibility of
anomalies uring the operation.
To i entify an to fin out its own instruments, Diapath S.p.A. uses some internal proce ures in which we
can fin pro uction recor ing, assembling recor ing, tests recor ing, serial number or batch co e an
configuration recor ing.

WEEE irective
7.1 Uninstallation an isposal
Before uninstalling the instrument, perform its econtamination, accor ing to current laboratory stan ar s.
Before transporting the instrument, insert it into a suitable packaging to minimize the risk of contact with the
parts of the instrument.
In compliance with EU Directive 2002/96/EC or waste electrical an electronic equipment (RAEE), this
electrical pro uct must not be ispose of as unsorte municipal waste. Please ispose of this pro uct by
returning it to the point of sale or to your local collection or recycling point.
The irective gives measures to prevent pro uction of electronic an electrical equipment waste an their
re-employment, recycling an other way of collection to re uce isposal waste volume.
The Directive RAEE/WEEE (electronic an electrical equipment waste) assists the ifferent collecting of
technological waste coming from the isuse of electric equipment malfunctione , broken or not repairable.
This irective RAEE (electronic an electrical equipment waste) intro uces the concept of “empty to return”
for the electronic an electrical waste, or rather the ol equipment with rawal when you buy a new one.
Diapath S.p.A. is an ecor’it member, global system of WEEE management (electronic and electrical
equipment waste) home and professional in the Italian territory.
To guarantee an efficient and effective system of separated collection of WEEE for the Italian territory, in
accordance with the law device, ecor’it uses suppliers that are the better of existent reality concerning
disposable technique, withdrawal and recycle.
In the European territory the RAEE responsible (electronic an electrical equipment waste) is the
manufacturer.
The European irective 2002/96/CE of European Parliament an council of 27
th
January 2003 on “electrical
an electronic equipment waste WEEE” efines manufacturer who:
i. Pro uce or sell electronic an electrical equipment un er its bran ;
ii. Sell un er its bran equipment pro uce by other suppliers. The reseller is not consi ere
as “the manufacturer” if the equipment has manufacturer’s tra emark accor ing to the point
I;
iii. Imports or exports electronic or electrical equipment to a member state concerning a
