Working environment
The calibrator units are designed to work safely under the following conditions:
Ambient temperature range: 5°C/9°F to 40°C/104°F
Humidity: Up to 95% relative humidity, non-condensing

HIGH TEMPERATURES ARE DANGEROUS: They can cause serious burns to operators and ignite combustible
material. Omega has taken great care in the design of these units to protect operators from hazards, but
operators should pay attention to the following points:
• USE CARE AND WEAR PROTECTIVE GLOVES TO PROTECT HANDS
• DO NOT put hot objects on or near combustible objects
• DO NOT operate the unit close to inflammable liquids or gases
• DO NOT place any liquid directly in your unit
• At all times USE COMMON SENSE
Operator Safety
All operators of Omega Engineering equipment must have available the relevant literature needed to ensure their
safety. It is important that only suitably trained personnel operate this equipment in accordance with the
instructions contained in this manual and with general safety standards and procedures. If the equipment is used
in a manner not specified by Omega, the protection provided by the equipment to the operator may be impaired.
All Omega Engineering units have been designed to conform to international safety requirements and are fitted
with a preset over-temperature cutout. If a safety problem is encountered, switch off at the mains socket and
remove the plug from the supply.

Installation
1
. All Omega units are supplied with a power cable.
2
. Before connecting the mains supply, check the voltage against the rating plate. Connect the mains
cable to a suitable plug according to the table below. Note that the unit must be earth grounded
to ensure proper electrical safety.
Electrical connections:
220V-240V
110V-120V

The fused plug supplied with the mains lead for use in the UK is fitted with the following value fuse to
protect the cable: 230V UK 4 AMP
The fuse in the unit protects the unit and the operator
Note that units marked 230V on the rating plate work at 220V; units marked 120V work at 110V. In
both cases, however, the heating rate will degrade by approximately 8%. The rating plate is on the
rear of the unit.
3
. Plug the mains cable into the socket on the rear of the unit.
4
. Place the unit on a suitable bench or flat workspace, or in a fume cupboard if required, ensuring that
the air inlet vents on the underside are free from obstruction.
After use, when you have finished heating samples, remember that parts of the unit may be very hot.
Take the precautions listed earlier.
