Window Maintenance Manual
General Description
The FR7650TSH (True Single Hung) windows are constructed from cold rolled
steel sections. It is equipped with a self-closing mechanism. This mechanism is
contained in a vertical position on the exterior jambs of the window. Its purpose is
to close the window in case of fire. The mechanism consists of balancers held in
position by a 165˚ fusible link. The balance is connected to the frame and
underside of the operable sash. Once the fusible link releases, the balance
disengages releasing the sash into the closed position.

Glass Replacement
The glass on FR7650TSH Window is easily replaced by removal of the metal glazing beads.
Glass must be UL Certified to retain the 45 to 90 minute rating.
1) Start by removing all of the screws from the glazing beads and muntins.
2) Once the screws are removed begin removing all glazing beads beginning with the
muntins first. Carefully pry the glazing bead from the window starting with the interior
or shorter sections first. Once the interior items have been removed, such as the glazing
bead and muntins, score the silicone on the exterior and/or interior with a utility knife to
separate the glass from the frame.
3) Clean debris from the interior of the frame using a cleaning solution making sure to remove
all traces of old glazing tape. Apply new glazing tape to the perimeter of the frame.
4) The replacement glass must be ¼” wire or fire rated ceramic glass rated for use in the
application. Minimum size of the glass is 7/8” larger than daylight opening of the sash.
Glass may be up to 1” larger than daylight opening.
5) Next, add setting blocks and begin installation of glass.
6) Replace last perimeter glazing bead removed back into original position. Next, replace all
remaining glazing beads starting with the last bead removed, working backwards. If used,
replace muntins and finally seal the exterior of the frame with glazing sealant.
CAUTION: This window contains a fusible link triggered at 165°, releasing spring tension
and forcing the sash closed. Do not use a torch to remove glazing products or cause heat to
be applied to the fusible link. Doing so may cause rapid closing of the window, causing
severe injuries. (See warning page 4)

Procedure for Adjusting Balancers
Sashes should also be checked for smooth operation. If there is too much clearance from side to
side it may be adjusted at the corner of the sashes. There are guide blocks in the corners of the
sashes which move in and out to adjust the clearance (see Adjusting the sash clearance). Selfclosing windows have a fusible link at the top of the balancer which should be checked for
damage.
1) Determine which balancer is used. All sashes use Ultralift or similar type balancers. Ultralift
balancers casing is grey with hexagon shaped nylon spring retainer at lower end. Balancer
weight and length should be indicated via laser etching on casing surface.
2) Lift Sash to uppermost position to unload balancer as much as possible.
3) Prop up sash with sturdy board. CAUTION: Sash may weigh as much as 100 lbs. a falling
sash will easily break bones and amputate fingers.
Ultra-Lift
� RATED AAMA CLASS 5, LIFTS 70% OF
SASH WEIGHT. MAKES HEAVY SASH EASY TO LIFT
� FOR SASH WEIGHTS UP THROUGH 80 LBS
� 670" TUBE DIAMETER
� CUSTOM MADE FOR SPECIFIC WEIGHTS
Ultra-lift Balancers
Ultra-lift balancers are adjustable to about 5 lbs. higher and to about ten pounds lower. They are
pre-tensioned at the factory to have length and sash weight stamped near the bracket end.
Bracket must be removed to adjust Ultra-lift taking care not to let balancer rod spin. Remove
screw furthest away from balancer and grip the bracket with a pair of locking pliers. Balancer
rod must be pulled out of balancer several inches to disengage tension lock then it should turn
freely either CW to increase or CCW to decrease the tension.

Balance Replacement
CAUTION: SASHES MAY WEIGH UP TO 100 LBS. AND BALANCERS HAVE
SPRINGS WHICH ARE VERY POWERFUL. USE EXTREME CAUTION WHEN
REMOVING BALANCERS.
1) Remove screws on balancer covers on the interior face of the window. Most windows
also have screws at the center of the cover which can be accessed from behind the cover.
Remove the covers marking the top or bottom so that they may be installed in the same
way.
2) Open sash and prop up with a strong piece of wood (be aware that large sashes may
weigh up to one hundred pounds).
3) Release tension on the balancer by one of the methods outlined in Adjusting Balancers
procedure.
4) Remove balancer mounting at the sash by removing the screws holding the balancer
bracket. Remove screw at the top of window holding balancer to jamb. Balancer may
now be removed by letting the sash all the way down and pulling the balancer up
through the track.
5) Remove the four screws at the corners of the sash. Push the glide blocks toward the
center of the window. If the blocks do not move then lightly tap the top and bottom rails
of the sash to loosen up the tension on the plastic blocks.

WARNING
NOTICE TO USERS OF FUSIBLE LINKS: In ALL handling of fusible links, care must be
exercised to avoid any abuse or injury that could cause deformation, bending or mutilation,
such as by a hammer, sharp tool, etc. Such damage could affect adversely the proper "breakaway" of the fusible link and cause a malfunction. Any fusible link showing evidence of damage
MUST NOT BE USED. Care must be exercised to select the correct "break-away" temperature
fusible link in relation to the surrounding environment. For example, ordinary temperature
links could "break-away" if placed too close to a hot radiator.
