Installation hints
This section provides information which may assist in the installation of the water cooler.
If the location of the water cooling system is more than three metres from the instrument, a
larger capacity water cooling system may be required. For every 1 metre that the cooling hoses
are lengthened, an extra 300 mL of cooling water will be required to fill the cooling system.
To minimize pressure build up in the water cooling system when lengthening the cooling hoses,
do not use hose/pipe which is smaller in diameter than the standard cooling hose supplied with
the instrument. Avoid sharp, restricting turns and angles (<90°) in all fittings and connections
used.
The maximum vertical rise from the water cooler to the instrument is 4.5 metres (15 feet). The
limiting factor is the cooling water flow interlock switch in the instrument.
At installation or re-commissioning, air may be introduced in the water cooling system lines.
Using lines longer than 4.5 metres may allow the introduction of large volumes of air into the
system. These trapped air pockets may cause the centrifugal pump to intermittently lose flow.
This may cause the flow switch to shut off the plasma during operation.
High ambient temperatures in a laboratory and high system water pressure can cause the
electrical current drawn by the water coolers to be higher than the typical figures quoted by the
manufacturer. Mains outlet supply connections should be as recommended in section 2 of this
manual.
Assembling and commissioning
1 Thoroughly inspect the water cooler for any visible sign of damage. If the unit shows any sign
of damage then steps should be taken to alert the customer who should notify the freight
forwarder, carrier or the local agent to lodge a transit damage claim.
2 Refer to the water cooler operation manual and check that all of the components listed are
supplied with the water cooling system.
3 Visually determine from the label fitted on the back of the water cooler that the water cooler
is configured for 50 Hz or 60 Hz as required.
4 Using the water cooler operation manual as a reference, complete the assembly of the water
cooler.
The Agilent 5110 ICP-OES instrument systems have a maximum water cooling inlet pressure of
440 kPa (58 psi). When using water cooling systems with a Positive Displacement pump, a
water pressure regulator should be fitted. These are often included within the cooler, but some
models may not have these regulators installed therefore an external pressure regulator should
be fitted. The water pressure regulator should always be set below 440 kPa (58 psi) before
attaching the water cooler to the Agilent 5110 ICP-OES instrument system.
