UV-1 should be installed on a stable, flat surface away from all sources of vibration. The atmosphere should be free of both excess humidity and corrosive or contaminated vapours which may form deposits on the component in the optical path.

UV-1 can be installed either in a coldroom or at ambient temperature in the laboratory. To minimise drift, the temperature should be kept constant. UV-1 optical unit should be positioned away from all sources of draught, heat and direct sunlight. UV-1 should be placed away from any compressor and the fan stream from coldboxes and col- drooms.

The UV-1 may be operated ambient temperatures in the range 0-40 °C (20-30 °C at full specifications).

One mains power point is required to operate UV-1. Separate power points are required for all ancillary equipment, such as recorder.

The power consumption of the monitor is max 20 VA.

Note: It is important that the interference filters and flow cells should not be handled during unpacking. For protection of these items they should remain in their packing materials until required for use.

Carefully unpack the UV-1. Check the contents against the packing list supplied. Inspect for any damage that may have occurred during transit. Report any damage immediately to the local GE Healthcare representative and to the transport company concerned. Save

the packing material if future transport can be foreseen.

The instrument is supplied with mains cables and fuses for both 100-130 V and 220-240 V operation.

1.Ensure that the mains switch (Fig. 5:16) on the front panel of the control unit is in the OFF position.

2.Select the correct value of fuse from the fuse kits supplied. For 110-130 V operation, use the 250 mA fuse supplied. For 220-240 V operation, use the 125 mA fuse supplied.

Insert the fuse into the fuse cap, and then fit the fuse cap into the fuse holder on the rear panel (Fig. 6:18) of the instrument.

3.Check that the mains voltage selector (Fig. 6:17) on the rear panel of the control unit is set to the mains voltage in the laboratory. If necessary, turn with a thick bladed screwdriver the mains voltage setting until appropriate setting is indicated in the small window.

Note: Use the 220 V setting for a 230 V mains outlet.
