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
a hole in the Lower Rear Panel 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 (Ext. 259).
MONTHLY...
Check the oil level in the Compressor while the motor is not running. The Compressor Oil Level Sight Tube is on the left side
of the lower section of the AC880 as viewed from the front. Remove the front panel from the AC880. The oil level should be
approximately one half inch high in the Sight Tube. If oil is not visible or is above the top of the Sight Tube call Technical
Support at 800-468-2321 (Ext. 259).
Clean the Condenser to maintain high efficiency performance of the AC880. Disconnect power and remove the lower rear
perforated panel 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 #” 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
# 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 Hour Counter is reset when the “CHANGE FILTERS
#” message is cleared. Record the filter changes performed to track
when only the “INLET” Combo Filter is changed versus when both are changed.
