3.Installing
Balances |
Note
that the shorter pair of balances is normally for the top sash, given
sashes fo equal height. With the sashes lowered, insert the appropriate
pair of balances into the grooves (fig 8). In the case of unequal size
sashes it is possible to slightly bow the balance for the insertion
into the groove of the larger sash. In some cases, larger sashes may
have to be removed.
|
Fit
the top of the balances to the frame jamb at the centre of the groove
tight up against the frame head, with the flat of the foot atachment
against the jamb. Fix using woodscrews provided (Fig 9).
|
To
attach balances to sashes, firstly raise the sashes as high as possible
and prop in position. The foot attachment at the bottom of each balance
should now be visible. Using pliers or vice grips, pull the foot attachment
straight down, sufficiant to clear the spiral rod protruding from the
lower end of the balance. (fig 10)
|
Now
fold the foot attachment under the bottom rail of the sash and carefully
release the tension of the balance (Fig 11). |
Using the woodscrews
provided, fix the foot attachment to the underside of the bottem rail,
ensuring that the balance is kept tight to the sash. *Fig 12).
|
Alternative
method |
For unequal
sashes, very heavy sashes and/or sashes with horns.
Before
inserting balances into the grooves, tie a loop of strong cord or wire
around the foot attachment as shown (Fig 13)
Proceed as previously described, using this loop to pull the foot attachment
downwards and across under the bottom rail of the sash. Fix using woodscrews
provided, before fully tightening screws, remove the cord or wire from
the foot.
.For
sashes with horns, using standard horn channel attchments(pre fixed in
Section 1 Fig 4 and Fig 5) use the loop to pull the balance foot down
so that it can be located into the bottom of the channel and then carefully
released (Fig 14). Remove the loop of cord or wire
