HANDLING OF COMPONENTS
1.
Upon receipt, inspect the shipment to ensure it is in
good condition.
2. Make sure that the small cardboard box with the
hinge pins and other hardware does not get lost.
3. Store in a clean and dry location and protect against
defacement or damage, especially to the edges of
panels.
PREPARATION OF THE ROUGH OPENING
For necessary clearance and adjustment space, rough
opening is suggested to be 3/4
"
wider and 3/8
"
- 1
"
higher
than the outside frame size of the unit ordered (check to
comply with applicable codes for maximum shim space
allowed, especially in high windload areas). It is important
that the opening be the correct size. Note that the
outside frame height of the unit ordered is measured
from the bottom of the sill and not from the finished
floor. Allowance must be made in height for the portion
of the sill that is below the measured opening.
PLEASE NOTE
– Because of the large opening sizes and
the weight and movement of the panels, any application
should take into consideration the following:
1.
The structural integrity of the header is critical for
proper operation. Vertical deflection of the header
under full live and dead loads should be the lesser of
L/720th of the span and 1/4
"
. Structural support for
lateral loads (both windload and when the panels are
stacked open) must also be provided.
2.
A qualified engineer or architect should be used to
determine the proper construction details and header
to be used in your particular application.
3.
THE ROUGH OPENING SHOULD BE LEVEL, PLUMB
AND SQUARE AT ALL POINTS. THERE SHOULD
BE NO UNEVENNESS OR BOWING. MAKE SURE
THAT THE HEADER IS NOT TILTED OR TWISTED.
THERE SHOULD BE NO BUMPS ON THE FLOOR.
THE SIDES SHOULD BE IN THE SAME VERTICAL
PLANE AND NOT OFFSET OF EACH OTHER.
A TRANSIT AND OTHER SIMILAR PRECISE
MEASURING EQUIPMENT SHOULD BE USED.
4. With a recessed sill, if concrete is to be poured after
the installation of the unit, the sill has to be securely
attached to the construction. If the sill is to be cast
in concrete, then an expansion gap with appropriate
material has to be created next to the sill.
5. With a low profile saddle sill some resistance to
water infiltration may be achieved by installing drain
connections to the outside.
If any anchorage or drain connection holes are made
through these drain channels, make sure that they are
properly sealed to prevent any water leakage. The open
ends of these drain channels at each end of the sill
should also be properly sealed.
Alternative anchoring
systems for the sill (without using screws through the
drain channels) are using L brackets attached to both
sides of the sill.
6. For better performance and protection, any exterior
folding system should be installed under an overhang
or with other similar protection.
7.
For better performance it is recommended that
all dead loads such as upper levels, roof, etc. be
constructed before a unit is installed.
Properly flash and waterproof around the perimeter
of the opening, especially at the sill. Make sure you
seek proper professional advice for the appropriate
construction needed for your particular application.
Do not install unit in structures that do not allow for
proper management/drainage of moisture.
