Additional instructions on how to connect the duct detector testing
hose:
1. Connect the optional duct detector testing hose (connector-hose) to the hose fitting from your tester
as shown in the figure above. Do not connect any wands.
2. If the duct detector can be reached through an access panel door, extend the hose into the duct and
place it over the inlet tube of the detector (see figure on the previous page). If not, remove the duct
detector and perform the same procedure.
3. Turn the tester on. Adjust the dilution control knob to set the dilution LED indicator to green “OK”
position.
