9. MAINTENANCE
This Section describes the scheduled maintenance procedure for the AWMT.
CAUTION!
Improper maintenance of the AWMT may void the warranty.
9.1 PREVENTIVE MAINTENANCE
This product requires minimal 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 the safety requirements and issues
related to the equipment. Read and practice the safety guidelines in
Section 1
9.2 MECHANICAL PREVENTIVE MAINTENANCE
Mechanical preventive maintenance consists of verifying the condition of all mechanical parts,
with the AC (or DC) 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 discoloured, 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 FAN CHECK
The AWMT is forced-air cooled, using a single fan. The cooling fan is located at the bottom
shroud. Verify that the fan is operating smoothly. Any suspect noise may indicate a worn fan
that must 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. The fan should be replaced every two
years, in order to ensure the proper cooling of the AWMT.
WARNING! Do not come in contact with any electrical assembly while power is applied.
