Section 8: Maintenance

8.1 Preventive Maintenance

1. Keep the pressure vessel lid bolts lubricated using an anti-seize  

     agent. Repeated insertion and extraction of stainless steel bolts  

     in a stainless steel vessel without using anti-seize paste can             

     cause galling. Lower speed insertion and extraction of bolts can  

     also help to prevent galling. Use ¼ to ½ the speed for   

 

     steel in steel.

2. Periodically lubricate the O-ring with silicone lubricant. The    

    O-ring is made of synthetic rubber and is located in the pressure  

    vessel flange. Damaged or worn O-rings should be replaced with  

    the same material.

8.2 Changing Fuses

1. Control Circuit Fuse: The control circuit fuse is a 2 amp, 250 volt  

    5 mm x 20 mm BUssmann GMA (or equivalent) fuse. It is located  

    at the left rear of the system.

2. Heater Circuit Fuse: The heater circuit fuse is a 10 amp, 250  

    volt semiconductor-type BUssman GMA 2A (or equivalent) fuse.  

    It is located inside the left control cabinet. If the heater circuit  

    fuse should malfunction, contact the ATS Service Department at  

    +1-724-283-1212 for instructions on how to service this fuse.
