FRAME GLASS AND CABLE REPLACEMENT
NOTE: Special parts, options, and accessories should be
maintained as required.
Sashes occasionally require service. The glass may fog due
to the condensation of chemical vapors, and such materials
should be removed promptly by washing with water and
detergent to prevent etching of the glass.
WARNING
If cable is frayed or damaged, it MUST be replaced to
avoid personal injury or damage to the fume hood
1. Hold the sash in the closed/down position by clamping the
sash counterbalance cable to the top structural frame
member. In some situations, access to the top of the fume
hood may be gained by:
• Removing end panel if end of hood is clear - See Page 4.
• Removing front louver panel - See Page 21 and 22.
• Removing blower enclosure panels- See Page 16–18.
2. Remove the outer portion of the sash moulding strip on all
four sides of the frame. Use a flat blade screwdriver to pry
away from inner portion of moulding. Dispose of broken and
both portions of the sash moulding strip.
3. Press the four (4) sections of the inner sash moulding strip
over the sash frame edge.
4. Place the new sash glass onto the inner sash moulding and
hold in place.
5. Press the outer moulding strip into the groove of the inner
strip.
6. Remove clamps holding the sash cable in place and test for
balance.
7. Sash counterbalance cable is replaced by removing front
corner post (See Page 22) for access. Field repairs can be
made on existing cable if the problem is an end fastening
device or disconnection. If cable is frayed or broken, order
replacement cable – describe hood type, size and cable
length.
