MAINTENANCE

4.1 GENERAL

The 6300 has been designed to give optimum performance with minimum maintenance. It is only necessary to keep the external surfaces clean and free from dust. The sample area should always be kept clean and any accidental spillage should be wiped away immediately. To give added protection when not in use, the unit should be disconnected from the mains supply and covered with the optional dust cover (630 028). For longer term storage or re-shipment it is recommended that the unit be returned to the original packing case.

NOTE:	The 6300 Monochromator is a non-serviceable unit and no attempt should be
	made to repair this item. Failure to observe this recommendation will result in
	the loss of any Warranty Claim on this product. In the unlikely event of the
	monochromator requiring service or calibration, it is essential that the
	Manufacturer or your local Distributor be contacted immediately for advice.

4.2 LIGHT SOURCE REPLACEMENT

The only routine maintenance which may be required is the replacement of the light source if this fails. Failure should be suspected if lamp failure indicator appears on the display. This can be confirmed by looking in the sample chamber. The Tungsten Halogen lamp is available from the Manufacturer or your local Distributor (refer Section 5.2, Spares).

WARNING: DISCONNECT THE UNIT FROM THE MAINS SUPPLY PRIOR TO REPLACING THE LAMP. CARE SHOULD BE TAKEN WHEN REMOVING THE LAMP FROM THE HOLDER. ENSURE THE LAMP IS COOL PRIOR TO HANDLING.

1.Access to the tungsten halogen lamp can be gained via the lamp access panel, located at the rear of the unit (refer Section 2.4).

2.Slacken off the thumbscrew from the lamp access panel located at the rear of the 6300.

3.Remove the old lamp from the holder. The lamp is a plug-in fit and should be removed by gently easing it from the holder.

IMPORTANT: WHEN FITTING THE REPLACEMENT LAMP IT IS ESSENTIAL THAT THE GLASS ENVELOPE IS NOT TOUCHED. FINGER MARKS WILL DAMAGE THE LAMP. SHOULD ACCIDENTAL DAMAGE WITH FINGERMARKS OCCUR, THE SURFACE OF THE LAMP MAY BE CLEANED USING ISO-PROPYL ALCHOHOL.

4.Carefully remove the replacement lamp from the packaging, ensuring the glass portion of the lamp is not touched.

5.Insert the lamp into the holder, as illustrated, ensuring that it is fully pushed home.
