SERVICE REQUIREMENTS
Electrical Supply Requirements
The Gas Controller must be connected to a mains power supply. A power cord is supplied to connect
the workstation to the mains supply. If an alternative power cord is used is must be rated appropriately
for the power requirements of the Gas Controller, refer to Table 2. The Gas Controller must be
connected to a protective earth.
To ensure safe operation of the system, it must be connected to a supply of the correct voltage and
frequency as stated on the rating label shown.
The mains supply voltage fluctuations must not /- 10% of the nominal mains voltage.

Gas Supply Requirements
The gas regulator should provide a minimum supply pressure of 2 bar gauge. The maximum supply
pressure permissible is 3 bar gauge. See Table 4 below. A supply pressure greater than this will damage
internal components of the gas mixer and will invalidate the warranty.

Table 3: Standard Gases
For the gas supply we recommend direct connections of the gas cylinder regulator to ensure minimal
pressure drops and flow rate restrictions. Only the above stated gases are to be used with the system.
Failure to comply with this may cause the product to become hazardous.
Only the above stated gases are to be used with the workstation. Failure to comply with this may
