reservoirs and delivery systems that contain chemical
reagents and standards.

Take care if cleaning any spillages and observe all relevant
safety instructions. Wipe up any spillages using clean
water.

Perform general cleaning of the wet-section using a damp
cloth only – mild detergent can be used as a cleaning aid.
Do not use Acetone or any organic solvents.
ELECTRICAL

Isolate all high voltage supplies to the transmitter before
performing bottle / label replacement procedures.

The wet-section is vulnerable to electrostatic damage.
Wear an anti-static strap or dismantle the wet-section on
an anti-static workbench.

Ensure all electrical connections are kept dry at all times.
GENERAL

Shut off the external sample supply to the wet-section
before performing replacement procedures. When a
procedure is complete, restore power to the transmitter
