7.2.1
Replace the nozzle when its diameter has
increased by 1/16", or when suction diminishes
noticeably. To change the nozzle, unscrew the holding
nut from the gun end, and pull the nozzle from the gun.
Inspect the nozzle and o-ring and replace if worn or
damaged. Inspect the air jet cover replacing it before it
wears through will prolong the life of the jet. Insert a new
o-ring and nozzle, placing the tapered end of the nozzle
toward the jet. Screw the holding nut onto the gun.

View Window Cover Lens
7.3.1
Rapid frosting of the view window can be
avoided by directing ricocheting media away from the
window, and by installing a cover lens on the inside
surface of the window. Using cover lenses prolongs the
life of the view window.
7.3.2
The best way to install a cover lens is to remove
the window from the cabinet. If, for some reason, it is not
practical to remove the window, the lens may be applied
with the window glass in place.
7.3.3
To install a cover lens, carefully remove the
adhesive backing making sure the adhesive remains on
the lens, and apply the lens to the clean, dry, inner
surface of the view window. When the cover lens
becomes pitted or frosted, replace it.

laminated replacement glass.
7.4.1
Remove the two window frame nuts located on
the upper edge of the window frame, and swing the
window frame open.
NOTE: Ergo models are not

If the frame
is to remain open, for cleaning or other reasons, remove
it per Section 7.6.
7.4.2
Remove the old window.
7.4.3
Inspect the window frame gaskets, both on the
window frame and on the cabinet. If either gasket is
damaged, replace it per section 7.5.
7.4.4
Install a view window cover lens per Section 7.3.
7.4.5

over the window opening, making sure that all edges of
the window are centered and overlapping the window
gasket, and that the window is resting on the window
support tabs.
7.4.6
Swing the window frame into place and tighten
the frame nuts.

Window Gasket Replacement, Figure 21

around the view window, or if gaskets are worn or
otherwise damaged.
7.5.2
Remove the window and window frame per
Section 7.7.
7.5.3
Remove all the old gasket material and clean
the surfaces of the cabinet and window frame.

Peel a short section of adhesive backing from
the 5/16
-thick strip gasket, and adhere the gasket to the
center of the top edge of the window opening, as shown
in Figure 21. Peel additional backing as needed, and
work the strip around the radius of each corner, pressing
it firmly to bond. Trim the gasket to fit and compress the
ends to seal.
