Horizontal-Sliding Sash Installation for
the 8', 10', 12', & 16' Floor-Mounted
Hoods
The Floor-Mounted Hood with horizontal-sliding sashes is supplied with four
individual sash doors. These doors have been packaged separately during
shipment and require installation in the field. The doors should not be installed
until the lower sash track threshold has been properly installed. Each door
assembly is provided with two mounting brackets with nylon roller bearings. The
roller bearings have been positioned in the center location of each mounting
bracket to provide for maximum door adjustment. The upper header sash track
features two tracks that will support two of the door assemblies. Raise the door
panel up and into the upper track section on your hood and place the nylon roller
bearings directly in the track section. At the same time, position the bottom edge
of the door assembly into the corresponding lower track slot. As each door is
placed into position, slide the door the full length of the track assembly to assure
proper height adjustment. If the door drags in the lower track, adjust the nylon
roller bearing on the mounting bracket to raise the height of the door. Reverse the
movement of the bearing should the door assembly be too short and not fit in the
lower track properly. An average space of 1/4" to 5/16" should be left between
the bottom of each door and the bottom of the lower sash track for proper door
travel. Repeat this procedure for the four door assemblies and place two of the
doors on each of the front and rear track runners. Once proper door operation has
been achieved, the sash track threshold should be permanently attached to the
floor. Anchor bolts should be used in the holes provided in the lower sash track
threshold mounting. The anchor bolts are not supplied. RTV sealant can also be
used to hold the lower sash track threshold in position during normal operation.
See Figure 3-6 and Figure 1-2.
TIP: SHOULD YOU EXPERIENCE SLIGHT BINDING OF THE SASH
DOORS OR DOOR IN THE TRACK, SPRAY THE TWO SASH GLIDES ON
THE BOTTOM OF THE DOOR FRAME WITH SILICONE SPRAY.
