SCHEDULED MAINTENANCE
BEFORE EACH USE...Check the oil level in the Compressors DAILY before using. The Oil Level
Sight Glasses can been seen through slots in the front lower section of the AC800. The oil levels
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 Condensers to maintain high efficiency performance of the AC800.
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 AC800. Replace the panel before applying
power to the AC800.
FILTER MAINTENANCE
Monitor the Moisture Indicators for a color change from BLUE to PINK. When the AC800 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 (two on
each side) are located behind access panels on either side if the AC800.
The “INLET” Combo Filter (right most of the two) must be changed every 25 hours of operation OR
when the Moisture Indicator is Pink. Hours are indicated on the Filter Change Meter.
The “OUTLET” Combo Filter (left most of the two) must be changed every 50 hours of operation
OR when the Moisture Indicator is Pink. Hours are indicated on the Filter Change Meter.
1. Remove side Access 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, repair as necessary.
8. Replace Access Panel.
