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 RHS780. 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 RHS780. 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 RHS780. Replace the panel before applying power to
the RHS780.
FILTER MAINTENANCE
The RHS780 automatically keeps track of Compressor Run Time. The Display (6) will read “CHANGE FILTERS 5” after every 25
hours every time the program returns to the Main Menu or whenever the RHS780 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. Remove front panel to service the Combo Filters.
2. Disconnect Flare Fittings from top and bottom of filters.
3. Remove mounting nuts and filters.
4. Transfer filter insulation material to new filter as applicable.
5. Install new Combo Filters using hardware removed in Step 3.
6. Connect Flare Fittings to top and bottom of filters.
7. Check for leaks and repair as necessary.
8. Replace front panel.
