Other components include:
• Push/pull handles, other handles
,
or other hardware,
as ordered may not be pre-attached to the panels
and will be in the hardware box or shipped
separately.
• The layout drawing of your unit shows the upper
track components consisting of the head track in the
opening, how they are labeled and how they have
to
be connected. The joints for the transitions are
indicated and necessary connectors for connecting
different upper track pieces are provided.
• The location of the removable head track (RHT)
portion to insert the rollers on panels is indicated on
the layout drawing.
• The overhead door closer will be in the hardware
box
and is not pre-attached to the top rail and has to
be
installed in the field after final adjustments were
made.
• Specified floor sockets, pivot points
,
and floor closers.
HANDLING OF COMPONENTS
1.
Upon receipt, inspect the shipment to ensure it is in
good condition.
2. Make sure that all components and hardware, which
might be shipped separately do 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 OPENING AND SUPPORT
STRUCTURE ABOVE
Make rough opening width at least 1/2
"
wider than the
outside unit frame width and rough opening height about
3
/4
"
taller than the total unit height depending on how
l
evel the support structure above is.
See Sheet 2 of the
Installation Manual.
It is important that the opening be
the correct size.
Product performance that includes operation, depends
on
having the gap between the bottom of the panel and
the top of the finish floor be maintained at 7 mm (1/4
"
)
and also the gap between the top of the panel and the
bottom of the head track to be maintained at a nominal
gap of 23 mm (7/8
"
). The running carriages can be
adjusted, if needed. The finish floor needs to be
absolutely level across the length of the opening.
The track length and layout have been supplied based on
the configuration and sizes chosen and approved. Please
refer to the layout drawing of your particular CSW75
project, to determine the correct location of the support
structure (by others) and for the support of the head
track in the plane of the opening. It is important that the
system is properly supported at the top.
IMPORTANT
: Any application should take into
consideration the following:
1.
As the CSW75 system is a top-hung system, it is
essential that a proper substrate with the proper
size and thickness be used for the support structure
above in order to support the head track in the
opening.
2.
The structural integrity of the support structure 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
"
. It should
be designed to accommodate the total weight of the
