Adept PA-4 Air Filter Inspection and Cleaning
The air filter, located on the front of the chassis, should be
inspected regularly and cleaned
at
the first sign of dust or dirt buildup. The filter must be inspected and cleaned at least once
per month. Regular cleaning will prolong the life of the filter. If the filter becomes clogged
or unusable for any reason, order a new air filter. The PA-4 filter part number is
40330-11200.
1. Turn off the power to the power chassis and protect it against an unauthorized
return to service.
2. Open the front grill by loosening two screws and swinging the grill out.
3. Pull the air filter out and inspect it for dust or dirt particles. If cleaning is required,
use compressed air to clean the filter. (Follow all appropriate safety procedures
regarding the use of compressed air.)
4. Replace the cleaned air filter and secure the grill.
WARNING:
Dangerous voltages are present inside the
power chassis. Turn off the power to the power chassis
and protect it against an unauthorized return to service
before opening the front grill to inspect the air filter.
Failure to observe this warning could cause injury or
damage to your equipment.
