`
Completely read the General Installation Instructions and all other sections which pertain
to your project before starting work. These recommendations are for general erection
procedures only. For actual job conditions, see the details on the shop drawings. For
perimeter anchor types and spacing, refer to the approved shop drawings or consult the
project design professional.
Sash Removal
1. Remove both lower sash end caps.
2. Raise the lower sash so you can comfortably reach the
underside of the sash handle rail. If the sash travel has
been limited, the limit stops may have to be removed.
3. Remove the screws and come along bars from the bottom
of the lower sash handle rail.
4. The carrier body is located in the jamb pocket at the
bottom end of the sash side rails. A hook in the bottom of
the carrier body is held in place by a flex spring. Insert a
small screwdriver between the hook and the spring, giving
the screwdriver a slight prying motion. This will release
the hook.
5. Lower the sash slowly until the carrier body hook is below
the jamb hold down blocks. Raise the sash again until
the hooks engage the jamb hold down blocks. The carrier
body will be held in place when the sash is removed.
6. Lift the sash off the carrier body about two
inches and move the sash into one of the jamb
pockets as far as possible. Then swing the
opposite side of the sash inward.
7. After the sash has been removed, pull off the
HB00 tamper clips on the end of the balance,
just above the carrier body.
