Important service note:
The Faucet Panel mounted fume hood fitting has been designed such that future servicing of the
fitting's cartridge can be done from the (user's) side of the fume hood. To do this, insure that the
main supply valve to the fitting has been completely turned off and then purged by completely
opening the fitting and releasing trapped material into the fume hood atmosphere. Then, support
the entire fitting by holding the hold-down nut in place with a wrench, before loosening the
cartridge's cap nut.
This Panel mounted fume hood valve has been shipped as shown below to ease installation. It is
designed to be installed in a 45
˚ angled fume hood equipped with 1-1/2" (38.1mm) diameter ˚
mounting holes. Before proceeding with the installation, identify and familiarize yourself with all
of the components.
Important Note: The front load fume hood fittings described in these installation instructions
are available in both right hand and left hand models. Right hand models are marked on both
sides of the body with an "R" and left hand models are similar marked with an "L". Due to the
use of these fittings in both right and left hand fume hoods, the bodies are marked on both
sides with directional flow arrows. Regardless of the model used, the fittings are designed to
be installed such that the inlet is on the bottom.
