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 Left Side Panel of the RHS730. 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 RHS730. Disconnect power and remove the
panel below the filters on the rear of the RHS730. Blow compressed air through the cooling fins of the Condenser
(from inside of cabinet towards the vent slots in the side panel) to remove any debris. Do not bend the fins on the
Condenser coils. Air flow will be restricted causing damage to the RHS730. Replace the panel before applying
power to the RHS730.

FILTER MAINTENANCE

The RHS730 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 RHS730 is turned on as a reminder
to change the filters. Press ENTER to go to the Main Menu.

The INLET Combo Filter (left side on rear) must be changed after every 25 hours of operation.

RTI part number 026-80069-00.

The OUTLET Combo Filter (right side on rear) must be changed after every 50 hours of operation.

RTI part number 026-80077-00.

The Hours Counter is reset when the CHANGE FILTERS 5 message is cleared (refer to page 13). Record the filter
changes performed to track when only the INLET Combo Filter is changed versus when both are changed.
