Series 433 Triple Set Installation Instructions
SECTION IX: Glazing
(Includes Offset and Center-Set Glazing)
Step 3) Installing the Water Deflector
HWD1 - WATER DEFLECTOR
The HWD1 water deflector is designed to be universal. It may
need to be modified to fit certain glazing pockets. Install the
HWD1 at the ends of the intermediate horizontals only. It is
not required at heads or sills. Use a silicone type sealant to
adhere the HWD1 onto the intermediate horizontal. Ensure
that the HWD1 fits flush with the top of the intermediate
horizontal glazing pocket and smooth any excess silicone
sealant so water will flow easily over the water deflector.
Step 3A) Installing the Water Diverter
FW33 - WATER DIVERTER
Install the FW33 at the intermediate horizontals
only. It is not required at heads or sills. Use a
silicone type sealant to adhere the FW33 onto
the intermediate horizontal. Ensure that the
FW33 fits flush with the top of the intermediate
horizontal glazing pocket and smooth any
excess silicone sealant as shown in Figure 97
so water will flow easily over the water
deflector.
Step 3B) Installing SSG Horiz. Mullion
Bridge Assembly
K895 – SSG BRIDGE ASSEMBLY
Install K895 at the intermediate
horizontals only. It is not required at
heads or sills. Use a silicone type sealant
to adhere the K895 onto the intermediate
horizontal. Ensure that the K895 fits flat
on top of the intermediate horizontal
glazing pocket and smooth any excess
silicone sealant as shown in Figure 99 so
water will flow easily over the water
deflector.
Tool sealant smooth
and flat, as not to
interfere with glazing.
FW33
Apply silicone type sealant
across the horizontal mullions
before installing the FW33.
Press the water diverter into the
sealant and apply a bead of
sealant to the perimeter seam.
Tool into the horizontal and
vertical to achieve a watertight
seal at the diverter.
