9.0 MAINTENANCE AND INSPECTION SCHEDULE 

 
 

It is recommended that maintenance and inspection be done on a scheduled basis, Maintenance 
requirements will naturally vary widely for each installation and specific operating conditions. It is 
suggested that a complete inspection be performed with necessary maintenance at the end of the 
first month, the first three months, and the first six months. These inspections will be indicative of 
how often future maintenance will be necessary.  
 

Every Month 

 
A. 

Inspect air filters. Clean or replace as required. Replace if cartridge is broken. The time 
interval for inspection should be shortened if experience indicates unusual dust loading.

those connections at contactors, motor starters, and heater elements. 

 

Once Every Year
