WARNINGS

Follow local and national electrical regulations and procedures.

Do not defeat interlocks, remove connectors, disconnect equipment, open safety
covers, dismantle or modify equipment unless you are qualified and authorised to
do so and you are fully conversant with its operation and potential hazards or have
total assurance through your local electrical permit to work system that the
equipment has been made safe.

Make sure that the mains supply is fused at an appropriate rating and that it can
be isolated locally via a clearly labelled, clearly visible and easily accessible
isolating switch. Isolate the supply before carrying out any maintenance work.

WARNING

Do not attempt to administer first aid to someone who may have suffered electric
shock until the source of the shock has been isolated.
Mains voltages are present in the system. High voltages are used by the X-ray
tube and power supply. These can cause serious injury or death.
Only personnel qualified to work with high voltages and currents should perform
service or maintenance work on such equipment.

1. Safety Information

In normal operation the unit is designed to operate safely. All users of the KMW70
Water Cooler unit should be aware of potential hazards which exist in and around
equipment of this type and the ways of avoiding possible injury and equipment damage
which may result from inappropriate ways of working. A description of such potential
hazards and how to avoid them is given in this section.

1.1 Electrical safety

In normal use the user is protected from the dangers associated with the voltage,
current and power levels used by the equipment. Only suitably qualified personnel
should attempt to disconnect, dismantle or modify the equipment.

1.1.1 First Aid

1.2 Mechanical handling

The unit is heavy and requires careful handling. Use safe lifting procedures for heavy
items to prevent possible strain injury.

1.3 Modifications and service

The manufacturer will not be held responsible for the safety, reliability or performance
of the equipment unless assembly operations, extensions, re-adjustments, modifications
and repairs are carried out only by persons authorised by the manufacturer. It should be
stressed that those parts of the equipment which are interchangeable, and which are
subject to deterioration during operation, may significantly affect the safety of the
equipment.

2. Introduction

This manual applies to the KMW70 Water Cooler produced by Agilent Technologies.

2.1 Overview

The KMW70 Water Cooler has been designed to operate with the Nova microfocus X­ray source from Agilent Technologies, which is described in a separate manual.

2.2 Water-to-air and water-to-water modes

The KMW70 Water Cooler device can work with water-to-air or water-to-water heat
exchangers. To transfer the unit from one mode to another some extra parts are
required. They can be purchased from Agilent Technologies and will require assembly
by an Agilent Technologies engineer.

The KMW70 Water Cooler in water-to-air operation requires an external Air Cooler (see
Fig. 1a). This device transfers the heat to the environment and does not require an
external (ie.tap) water supply.

While operating in water-to-water mode the device contains a water Reservoir (see Fig.
1b) on the left-hand side of the electronic rack. It also needs an external water supply
(tap water, integrated building water circuit or additional water chiller, such as
Thermoflex 900) to cool the device.

2.3 Environmental parameters

The KMW70 Water Cooler is designed to operate indoors. In water-to-water mode the
air must have a temperature below 25 deg C. Sufficient air conditioning must be
installed in the room to ensure the correct air temperature.

To fill the KMW70 reservoirs use 1:10 solution of distilled water with glycol to prevent
the liquid and circuits from algae growth.
