Space required (Zetasizer APS)
Provide enough space to allow easy access to all components and connections. This
diagram shows the recommended space for a system. Always place the (optional)
PTC-1 to the left of the instrument as the heat output is from the left side of the
PTC-1 and this will prevent hot air being directed towards the APS.

Positioning the Instrument
Warning!
Do not position the instrument such that the power cord, where it exits the
product, is unreachable for disconnection.
Warning!
Do not obstruct the ventilation slots underneath the instrument, nor the
fans on the rear panel. Restricting airflow can damage the instrument or
cause overheating.
Replacing the system fuse
Warning!
Fuses must not be replaced by the operator. Only the supervisor or a
Malvern representative should attempt to change the fuse.
If the instrument does not power up, check the system fuses. These are located in
the mains power switch on the rear panel.
Before changing a fuse, disconnect the instrument from the mains power.
Pull the fuse holders out and replace any faulty fuses with ones of the following
specification:
Positioning the Instrument - Read in place of relevant section on page 3-1 of
the Zetasizer μV and Zetasizer APS Essentials Manual.
Replacing the system fuse - Read in place of relevant section on page 4-3 of
the Zetasizer μV and on page 4-2 of the Zetasizer APS Essentials Manual.

Access to the instrument
Malvern personnel
Malvern personnel (service engineers, representatives, etc.) have full access to the
instrument and are the only people authorised to perform all service procedures
that may require the removal of the covers.
Warning!
Removal of the main covers by unauthorised personnel, even a supervisor,
will invalidate the warranty of the instrument.
Supervisor
The supervisor is responsible for the management and safety of the instrument and
its operation. The supervisor also trains the operators. They can perform all user
maintenance routines identified in Chapter 4.
The supervisor has access to a more detailed manual in English.
Operator
An operator is a person trained in the use of the system. The operator can perform
all user maintenance routines identified in Chapter 4, except changing the fuse.
Warning!
Failure to follow these guidelines could result in exposure to hazardous
voltages and laser radiation.

ruptible Power Supply (UPS) to remove any spikes or noise. The power require-
ments are:
Power cords and Power safety
The notes in this section indicate best practice. Adhere to these when connecting
the instrument to the power supply.

General requirements
The following requirements apply to all countries:
The power cord must be approved by an acceptable accredited agency respon-
sible for evaluation in the country where the power cord set will be installed.
The power cord set must have a minimum current capacity of 10A (7A in Japan
only) and a nominal voltage rating of 125 or 250 volts AC, as required by each
country's power system.
The area of the wire must be a minimum of 0.75mm2or 18AWG, and the
length of the cord must be less than 3m.
The power cord must be routed so it will not be walked on, pinched by items
placed on or against it, or become wet. Pay particular attention to the plug, the
electrical outlet and the point where the cord exits the product.
Computer specification
As with any software, running other software at the same time may affect the speed
of the Zetasizer software.
Minimum recommended specification
Pentium P4 PC 2.8GHz, 512MByte RAM, 160GByte hard disk drive, 1024 x 768
screen resolution, CD-ROM drive, USB port, Windows XP Pro (SP2) operating
system.
Note:
A laptop computer must have a free USB port to operate with the system.
Networks
The PC running the Zetasizer software can be connected to a network, but the
Zetasizer software must be run locally.

Additional services
Purge specification
If measuring samples at low temperatures there is a risk of condensation occurring
on the cell; this occurs when the measurement temperature is less than the ‘dew
point’ of the ambient air surrounding the cell being measured. This is particularly
likely in humid climates.
If this may be a problem the purge inlet port can be used to connect a dry air supply
i.e. a supply with a dew point below the target temperature. This removes any
moisture in the air immediately surrounding the cell and prevents condensation. If
using the purge inlet connector, the air or Nitrogen supply must conform to this
specification:
Compressed air to DIN 8573-1
Oil = Class 1
Water = Class 3
Particulate = Class 3
Pressure = 100 kPa g
Caution!
The purge air line supply must conform to the above specification. Failure
to meet this specification may result in permanent damage to the instru-
ment and invalidate the warranty.
Telephone socket specification
The telephone socket for remote support needs a direct Internet connection.
Laser safety
Zetasizer μV instruments are Class 1 laser products and as such, require no special
laser safety considerations during normal operation. However, during servicing
(which must be performed by a qualified Malvern representative), the servicing
engineer may be exposed to class 3b or above laser radiation. We therefore recom-
mend that the administrative controls recommendations of the Laser Safety Regu-
lations (IEC 60825-1(1993) +A1(1997)+A2(2001) are implemented.

Health and safety
General warnings and Safety regulations
Warning!
The instrument or samples to be measured may be hazardous if misused.
Read and fully understand this section before operating the system.
Warning!
Use of the system in a manner not specified by Malvern Instruments Ltd
may impair the protection provided by the system.
The instrument must only be stored or operated in environmental conditions con-
forming to Chapter 2.
Electrical warnings and Safety
regulations
Warning!
The Zetasizer μV contains high voltage components. Only Malvern
trained personnel are permitted to remove its main cover.
The instrument is mains powered and all power cables and electrical sockets should
be treated accordingly. Do not place cables where they may become wet.
Should the instrument become wet (e.g. sample or dispersant is spilt), switch it off
and disconnect it from the mains power supply immediately. Scrupulously clean
and dry the instrument before re-applying power.

The notes in this section indicate best practice. Follow these when connecting the
instrument to the power supply.
Warning!
Do not operate this product with a damaged power cord set. Replace a
damaged power cord set immediately.
Warning!
Do not use the supplied power cord on any other products.
Power cord set requirements
Power cord sets must meet the requirements of the country where the product is
used. For further information on the requirements, contact a Malvern
representative.
