Replacement
1. Remove the FS nuts and bolts and then FS set from air
end.
2. Remove LP and HP tip seals from Fixed Scroll set and
Orbit scroll set. Using the tip of a ball-point pen at the
start will make it much easier to remove (See Figure 4).
3. Remove all dust from the Scroll wraps and tip seal groove
with clean cloth or compressed air before inserting the
new tip seals.
Maintenance (continued)
NOTE:
Replace tip seal on SLAE03EB and SLAE05EHP at 5,000
hours when operated at 145 psig.
The tip seal on the scroll compressor is self-lubricated
and allows the unit to operate effi ciently without oil and
expensive fi ltration. The tip seal should be replaced every
10,000 hours of operating @ 115 psig.
