SCHEDULED MAINTENANCE
BEFORE EACH USE...Check the oil level in the Compressor and Vacuum Pump
DAILY before using. The Compressor Oil Level Sight Glass is on the left side
of the lower section of the RRC770. The Vacuum Pump Oil Level Sight Glass is
on the end of the pump housing. The oil level should simply be visible in the
glass. If oil is not visible or is above the top of the glasses call Technical
Support at 800-468-2321.
MONTHLY...Clean the Condenser to maintain high efficiency performance of the
RRC770. Disconnect power and remove the lower front 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 and cause damage to the RRC770. Replace the panel before applying
power to the RRC770.
FILTER MAINTENANCE
Monitor the Moisture Indicator for a color change from BLUE to PINK. When
the RRC770 is new and immediately after changing Combo Filters, the Moisture
Indicators may show PINK. This is due to the exposure to air and does not
indicate inadequate filter performance. Combo Filters are located behind the
front (red) wrap around panel of the RRC770.
The “INLET” Combo Filter (front most of the two) must be changed every 25
hours of operation OR when the Moisture Indicator is Pink. RTI part number
026-80077-00. Hours are indicated on the Filter Change Meter.
The “OUTLET” Combo Filter (rear most of the two) must be changed every 50
hours of operation OR when the Moisture Indicator is Pink. RTI part number
026-80069-00. Hours are indicated on the Filter Change Meter.
1. Remove front (red) wrap around 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.
