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.

VP35 Suction Unit - Service Manual
5. MAINTENANCE
WARNING
Maintenance of the vacuum pump/motor
unit and associated components will
necessitate removal of the suction unit
cover. SWITCH OFF AND DISCONNECT
electrical supply to suction unit before
removing cover.
GENERAL
5.1 Apart from cleaning and filter
replacement, the suction unit does not
require frequent in-depth maintenance. The
pump oil level and condition need only be
checked after every 500 hours or 3 months,
unless contamination is suspected - in which
case the unit must be removed from service
immediately, cleaned and replenished with
fresh oil (see section 5.7). Also the pump
rotor blades should be examined for wear
every three months.
5.2 Should suction performance
deteriorate, it is strongly recommended that
an Eschmann service engineer be called to
deal with the problem (see inside front cover
for details). If this is not possible, then
provided that a competent engineer is
available, items such as blades, oil seal
gasket, oil wick and exhaust filter/silencer
can be examined and, if necessary , renewed
by hospital equipment maintenance staff.
CHECKING SUCTION PERFORMANCE
5.3 If at any time suction performance is poor
this can be due to an air leakage in the system
(e.g. split tubing, poor connection, worn or illfitting jar lids, chipped jar rims), blockage of
the disposable filter or exhaust filter/silencer,
or wear in pump blades or stator.
5.4 If deterioration of suction performance
is due to a blocked filter, the pump will still
produce a satisfactory reading on the
vacuum gauge, but if it is due to leakage in
the system or mechanical wear the vacuum
reading will also be poor. To check vacuum
performance of the suction unit, block off the
suction line by placing a finger over jar lid or
liner inlet nozzle and check the reading

3. Inlet non-return valve/adapter
4. Exhaust tube
5. Exhaust filter/silencer
6. Oil reservoir end cover
7. Oil filler plug

on vacuum gauge. Vacuum reading should
be 600mm Hg (at least) (atmosphere at
760mm Hg) with vacuum control valve
turned to maximum position.
Note: A low indicated vacuum could
also be due to a faulty vacuum gauge. If
there are no leaks and oil condition is
satisfactory, check gauge before assuming
pump mechanical failure.
CHECKING PUMP OIL
5.5 After 500 hours/3 months or if at any
time pump performance deteriorates,
proceed as follows:
i. Switch off pump, remove oil filler plug
(item 7, Fig. 2) and observe level and
condition of pump oil.
ii. If the level of the oil has fallen appreciably ,
add more of the high vacuum oil supplied
until the oil reaches the oil filler hole, then
install the oil filler plug securely. If the oil
appears dirty or contaminated, the oil
reservoir should be disassembled,
cleaned out and replenished with fresh
oil (see under ‘Pump blade replacement
and pump cleaning’ section 5.7).
S-SM02e Page 7 of 16

Section 5
VP 35 Suction Unit - Service Manual
5. MAINTENANCE
5.6 After 12 months use, the pump oil
reservoir should as a matter of routine
servicing, be disassembled, cleaned and
replenished with fresh oil.
PUMP BLADE REPLACEMENT and
PUMP CLEANING
CAUTION
The pump oil reservoir (item 10, Fig. 3)
and its front cover (item 1, Fig. 3) can be
removed for cleaning and blade
replacement purposes. Beyond this
point, disassembly should only be
undertaken by an Eschmann Service
Engineer. If a situation occurs where this
is necessary, in the absence of
Eschmann personnel, advice should first
be sought from Eschmann Equipment
or their local representative.
5.7 T o gain access to the pump/motor unit,
disconnect the electrical supply to the unit
and remove the suction unit top cover. In
order to carry out pump disassembly the
pump/motor unit must be removed from the
suction unit baseboard by removing the
fixing screws from the motor feet. Now refer
to Fig. 3 and proceed as follows:
i. Remove the oil filler plug (4) and drain all
the oil from the pump.
ii. Mark with a file the relative fixed positions
of pump stator (12), oil reservoir (10) and
end cover (1).
iii. Release and extract the four long screws
(8) from the oil reservoir end cover (1),
then separate the end cover and oil
reservoir from the pump stator .
lubricate each blade with Eschmann
‘Universal’ high vacuum pump oil before
inserting blades into their slots.
v. If the oil was dirty or contaminated,
thoroughly rinse-out the interior of the oil
reservoir, the pump stator, the rotor slots
and the inside face of the end cover . Use
only disinfectant and warm water or mild
organic solvents. When making up a
disinfectant solution avoid the use of
hypochlorites, which could damage the
pump interior surfaces. If the pump interior
has been badly contaminated, it may be
necessary to carry out further
disassembly in order to gain access to all
internal surfaces; this should be the
responsibility of an Eschmann Service
engineer (see cautionary note above
section 5.7). Rinse and dry all washed
components thoroughly, before
reassembling.
vi. Apply a film of clean high vacuum pump
oil to the stator bore, then reassemble the
pump components, fitting a new cork
gasket (9) and, if necessary , a new oil wick
(1 1). Align oil reservoir (10) and end cover
(1) with stator (12) by means of the file
markings, insert the four long screws (8)
and tighten them evenly and securely.
vii. Finally , add a charge (25ml) of fresh oil to
the oil reservoir, via the oil filler hole in the
end cover, using Eschmann ‘Universal’
high vacuum pump oil (see spares list).
Install the oil filler plug securely.
EXHAUST FILTER/SILENCER
REPLACEMENT
iv . Pump blades will eventually wear after a
long period of use; the minimum root to
tip dimension which a blade should be
allowed to reach is 11mm (Fig. 4). Note
the facing positions of the four pump
blades then extract each one, examine it
for wear or signs of damage and if
replacement is necessary change all four
blades at the same time (refer to Fig. 3).
Clean out rotor slots then clean and
5.8 The exhaust filter/silencer (item 7,
Fig. 3) which serves the double purpose of
arresting oil mist and reducing exhaust noise
cannot be serviced. Whenever the pump is
disassembled for cleaning or blade
inspection, or if it is noted that the filter/
silencer has become choked or fouled, it
should be renewed as a complete item. If a
filter/silencer is allowed to remain in this
condition, this could also cause loss of flow.
