Section 1
GENERAL
1.1 The VP35 is a high vacuum, high flow suction unit designed to conform with British
and International Standards EN 60601-1:1990+A1:1993+A2:1995, ISO 10079-1:1991,
BS 5724:Part 1:1979, IEC 601-1:1977, IEC 601-1-2:1993.
1.2 The suction unit can be supplied in three ways; either with a reusable jar and
disposable liner system as illustrated below in Fig. 1, or with T raditional Jars (see appendix
A), or with Eschmann Suction Jars (see Appendix B), or without jars and liners but
incorporating brackets to receive ‘Abbott Receptal’ style disposable items.
PUMP AND MOTOR
1.3 The vacuum pump is an oil lubricated electrically driven pump/motor unit of the rotary
vane type, with replaceable blades. The motor unit is designed to operate from the mains
electrical supply (see serial plate for unit voltage).
1.4 The pump/motor unit, its associated pipework and electrical connections are all
contained within a durable, hygienic plastic case. Controls are mounted on the top of the
case and comprise an illuminated* on/off power switch, a vacuum control valve and gauge.

1. INTRODUCTION
(* On later units the switch is not illuminated.)
1.5 A silencer unit in the pump exhaust line ensures that the pump operates with the
minimum of noise, while the pump inlet is protected by an externally mounted sealed
bacterial or combined hydrophobic/bacterial filter, both of which are disposable.
1.6 All the information necessary to maintain the VP35 portable suction unit in a
serviceable condition will be found in this Service Manual.

2. SAFETY NOTES
When servicing or maintaining the ESCHMANN VP35 SUCTION UNIT,
attention to the following points will prolong the life of the unit.
Section 2 & 3
DO clean and disinfect all suction equipment
and the unit thoroughly after use.
DO change the disposable filter after each
day’s use, or, IMMEDIATELY if wetted,
or, after aspiration of infective fluids.
DO unplug and/or isolate power lead before
cleaning suction unit and when not in use.
DO treat receiver jars carefully, avoiding
mechanical or thermal shock.
DO examine condition of jars, lids (including
float function) and suction tubing
regularly, replace if worn or damaged.
DO keep ‘sharps’ away from liners.
WARNING
The maintenance procedures described in this User Handbook should be made the
responsibility of the engineer in charge of services in the hospital. If maintenance is
neglected, suction performance could be found inadequate in an emergency situation.
It is also recommended that if placed on standby for emergency duty the unit is
tested by switching on, at regular intervals. Also consult the Instructions for Use for
additional warnings on safe use and the disposal of potentially contaminated liquid,
or solid, waste.
DON’T start unit without removing the
transit bolt and washer.
DON’T use substitute accessories (see
available parts list).
DON’T continue to use unit, without
attention, if vacuum or suction rate
is low.
DON’T use the mains lead or suction tubing
as a tow rope, use the unit’s handle.
DON’T use phenols or solvent based
disinfectants to clean receiver jar,
use Savlon, Hibitane or similar
(also see sections 4.1 - 4.3).

4. GENERAL CARE
CLEANING
WARNING
The equipment must be disconnected
from the mains electrical supply prior
to cleaning and disinfection.
4.1 The following routine should be carried
out immediately after each period of use:
i. Disposable filters must be changed after
each day's use, or IMMEDIATELY if
wetted, or after aspiration of infective fluids.
ii. All components likely to be in contact with
aspirated body fluids should be thoroughly
cleaned and sterilized after use, or
whenever it is suspected that infective
fluids have been in contact with the unit.
iii. The outside of the suction unit should be
washed with hot (55°C) detergent
solution, e.g. 0.1% Teepol or equivalent,
rinsed with clean water, and wiped dry.
iv. The jar inlet tube can be cleaned by
removing the jar lid and flushing the tube
through with water under pressure.
v. In case of undue frothing, for example,
moisture could be sucked past the cutoff
valve. If wetting of the filter indicates that
this has happened, the cutoff valve
assembly must be disinfected.
vi. Should the float cage, or rubber valve seat
be damaged in any way, the complete
cutoff valve assembly must be renewed.
vii. Phenol based disinfectants and solvent-
based liquids should not be used for
cleaning receiver jars, use aqueous
based liquids at all times.
STERILIZATION
method of sterilization for the jars is steam
autoclaving, if chemical techniques are to
be used only use aqueous based systems.
4.3 Jars and lids should be thoroughly
cleaned before autoclaving and all traces
of cleaning liquids removed by adequate
rinsing in water. (Also see section ‘vii’ of
section 4.1).
SUCTION UNIT DISINFECTION
4.4 The suction unit should be moved to a
well-ventilated area designed and used as
the disinfection area. Access to the area
should be restricted to those people involved
in the disinfection process. Initially the unit
should be cleaned as detailed above [4.1(iii)] and then disinfected as below:
i Wash down all surfaces and crevices with
a 70% solution of industrial methylated
spirit and water. Allow drying by
evaporation at room temperature.
ii All infected or soiled cleaning materials
should be disposed of safely and carefully ,
taking into account any National, Local or
Hospital procedures covering the disposal
of potentially contaminated waste.
DAILY CHECKS
4.5 To ensure the VP35 Suction Unit
operates efficiently in an emergency, the
following checks should be carried out daily:
i. Check jar cutoff valve for free movement.
If valve action is faulty , rectify or renew lid
assembly .
ii. Check jar for cracks or chips in rim. Renew
if damaged. Renew rubber bung if
hardened, split or damaged.
CAUTION
To avoid cracking the jar by thermal
shock, place it towards the rear of the
autoclave shelf and open the door
slowly. Do not use phenols or solvent
based disinfectants to sterilise jars.
4.2 The jar lid assembly can be sterilized
by all normal methods including high
pressure autoclaving. The most suitable
iv. With suction unit switched ‘on’, vacuum
control valve turned up to maximum and
suction line blocked off, check reading on
vacuum gauge moves quickly to at least
600mm Hg (atmosphere at 760mm Hg).
Service unit if vacuum value low .
Note: Disposable filters, suction
tubing, jars and disposable liners are
relatively inexpensive items, and a stock of
spares should always be readily available.
