Original instructions
Sash Removal
There are two (2) sashes to be removed on the Pass-Through hoods. Please repeat the
procedure for each sash.
1. Remove the sash end stop brackets by removing the two (2) #10-24 screws on each
end stop bracket. The sash cables are attached through these end stop brackets.
2. Now the glass sash assembly can be removed by sliding it up and out.
Note - Sash weights are mounted in retention tracks on one side of the Pass-
Through hood. They do not need to be removed to remove the sash(es). If sash
weight removal is desired, see Chapter 3: Sash Weight Release.
Airfoil Removal
1. Remove lower corner post screw located under the airfoil.
2. Remove the airfoil by removing the rear screws located on top of the airfoil on each
side.
Transport and Reassembly
The various subassemblies are now ready to be transported and reassembled in the
opposite way the hood was disassembled. All hoods will require a minimum of five
people to lift the hood, two people on each side and one in front (for balance only). A
hydraulic lift table should be used as an aid in lifting. If in doubt about lifting the hood,
always reassemble the hood where it will be placed.
Sash Weight Reassembly
After the hood is assembled, the sash weights are easily installed before the hood is
installed in a wall, because the wall may reduce access to the side panel and the sash
weights behind the side panel. Please keep this in mind and install the sash weights
now.
Hood Replacement and Service Installation
The hood is now ready for placement and the HVAC, plumbing and electrical service can
be installed.
