9. MAINTENANCE 

 

This Section describes scheduled maintenance procedure for the SSPA/system. 

 

 

CAUTION:

 Improper maintenance of the SSPA unit may void the warranty.

 

9.1 PREVENTIVE MAINTENANCE 

 

This product requires minimum maintenance, which consists of visual inspection and cleaning. 

 

 

WARNING:

 The person performing maintenance of this equipment must have training

and knowledge of both the product and safety requirements and safety issues related to the
equipment. Read and practice the safety guidelines at the beginning of this manual (

Section 1

SAFETY

 

at page 6). 

9.2  MECHANICAL PREVENTIVE MAINTENANCE 

 
Mechanical preventive maintenance consists of verifying the condition of all mechanical parts, with 
the AC power switched off.  Perform the following inspection: 

1.  Check all connectors and plugs for evidence of damage and improper seating.  Replace 

defective connector plugs and reset any that are dislodged. 

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

replace if necessary. 

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

Tighten or replace waveguides as required. 

4.  Check for other defects such as, wear, breakage, deterioration, fungus, excess moisture and 

mounting integrity. 

 

9.3 COOLING FANS CHECK 

 

The SSPA unit is forced-air cooled, using three fans. The cooling fans are located at the bottom 
shroud of the SSPA. Verify that the fans are operating smoothly. Any suspect noise may indicate 
wear and the fan will have to be replaced. Check for debris or dust in the fans intake and in all 
openings on the unit. This may reduce the efficiency of the cooling system. The fans should be 
replaced every two years, in order to ensure the proper cooling of the unit. 
 

 

WARNING:

 

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

applied.
