Insert tip seal so that the lip of tip seal is on the bottom of seal groove and inner side of involute and the direction of lip
faces the center of involute (curving spiral). See Figure 5. This is to be done for both FS and OS sets.
Use caution not to tear or distort lip.
•
Insert new HP tip seal from the center section for OS or Orbit Scroll so that there will be no clearance at the tip
(start) section (See Figure 5 and 6).
•
Insert so that new LP tip seal will contact closely with HP tip seal inside Scroll Groove.
Insert approximately half of the LP tip seal and remove the tip seal to confirm
that a notch in the tip seal has been created. This will prevent movement
during installation (See Figure 8).
•
Repeat the same procedure for FS or Fixed Scroll tip seal set, remove both the dust seal and backup tube located
on outermost side FS set.
