SCHEDULED MAINTENANCE
DAILY...
Check the oil level in the Vacuum Pump while the pump is running. The Vacuum Pump Oil Level Sight Glass is visible
through vacuum pump sight glass on the rear of the AC880. The oil level should be at the “half-way” point of the glass. If oil
is not visible call Technical Support at 800-468-2321 extension 259.
MONTHLY...
Clean the Condenser to maintain high efficiency performance of the AC880. Disconnect power and remove the plastic front
cover and blow compressed air through the cooling fins of the Condenser to remove any debris. Do not bend the fins on the
Condenser coils. Air flow will be restricted causing damage to the AC880. Replace the panel before applying power to the
AC880.
FILTER MAINTENANCE
The AC880 automatically keeps track of Compressor Run Time. The Display will read “CHANGE FILTERS 5” after every 25
hours every time the program returns to the Main Menu or whenever the AC880 is turned on as a reminder to change the filters.
Press ENTER 5 to go to the Main Menu.
The “INLET” Combo Filter (left side) must be changed after every 25 hours of operation. RTI part number 026-80077-00.
The “OUTLET” Combo Filter (right side) must be changed after every 50 hours of operation. RTI part number 026-80069-00.
The Hours Counter is reset when the “CHANGE FILTERS 5” message is cleared. Record the filter changes performed to track
when only the “INLET” Combo Filter is changed versus when both are changed.
Change the filters as described below:
1. Disconnect Flare Fittings from top and bottom of filters.
2. Remove mounting nuts and filters.
3. Transfer filter insulation material to new filter as applicable.
4. Install new Combo Filters using hardware removed in Step 2.
5. Connect Flare Fittings to top and bottom of filters.
6. Check for leaks and repair as necessary.
7. Go to Page 12, Accessing Stored Data, for instructions on how to remove the “CHANGE FILTERS 5” message.
