Section 5 - Maintenance

5.1  

Calibration

This unit has been fine tuned at the factory and calibrated to give optimum 

performance of its full temperature range. It is recommended that the unit be 

returned annually for re-calibration.

5.2  

Cleaning

  

CAUTION:

Remove all electrical connections and power before  attempting any maintenance or 

cleaning.

 

5.2.1 

 Main  Body

 

Only a damp soft rag with a mild cleaning solution should be used to clean the 

main body of this unit.

 

5.2.2  

 Target Plate

 

Do not attempt to clean the target plate. The target plate has a special coating 

applied and cleaning may change the emissivity and performance of your unit.

 

5.2.3 

 Fan

 

The fan filter should be removed and cleaned as a minimum, monthly, by 

washing the filter with warm water and then blowing dry with air. It can 

be removed by firmly pulling the black plastic frame outward. The internal 

protective grill that is seated against the fan can be cleaned with a soft bristle 

brush.

5.3  

Fuse Replacement

 

 

WARNING:

Disconnect all power from source before attempting fuse replacement.
