AINTENANCE

 

Mechanical preventive maintenance consists of verifying all mechanical parts. Most of them are 
performed with the AC power switched off. Perform the following inspection: 
 

1.  With the AC power disconnected or switched off, check that all connectors and plugs are 

properly seated in their mating connectors and have not been damaged. Replace any bad 
connector plugs and reset any that are dislodged. 

 
2.  Inspect electrical wiring for signs of discolored, broken or bad insulation. Repair or 

replace as needed. 

 
3.  Inspects all waveguides for discoloration, cracks, loose connectors and improper sealing. 

Tighten or replace waveguides as required. 

 
4.  Check for other defects. These include, but are not limited to, wear, fungus, breakage, 

deterioration, excess moisture and mounting integrity. 

 

8.1.2 C

HECKING THE 

C

OOLING FAN

 

The cooling fan is located at the back of each unit. Verify that the fan is operating smoothly. Any 
suspect noise may indicate wear and fan will have to be replaced. Check for debris or dust in the 
fan intake and in all openings on the unit. This may reduce the efficiency of the cooling system.  

 

 

WARNING

: 

Do not come in contact with any electrical assembly while power is on.
