6. Locate the alarm module in the electrical cutout in the corner cover or side
panel of your hood, being careful not to pinch either the electrical wiring
or sensor tube. Lock the bottom of the alarm module in place by sliding
the bottom edge of the assembly down over the edge of the cutout. Next,
secure the top of the alarm with the two #6-32 screws. Mounting holes for
these screws are located underneath the black label surrounding the
electrical cutout. Leave the label in place and secure directly through it to
the corner cover.
7. Route the wiring and plastic tubing up the backside of the corner posts and
attach as shown. Refer to Installation Drawings.
NOTE: Make sure to keep the tubing and wiring out of the travel area of
the sash weights.
Power Supply Module
1. Locate the power supply module on the top of the fume hood liner
assembly and use the supplied Velcro strips to secure in place.
2. Drill a 3/8" diameter hole in the hood exhaust collar or blower housing,
depending upon your specific model of fume hood. Refer to Installation
Drawings for exact locations.
3. Insert the velocity probe into the open end of the vinyl tubing and position
the probe in the 3/8" diameter hole drilled in Step 2. Place the end of the
airflow hose with the nozzle inside the hose near the exhaust duct as
the nozzle helps regulate airflow properly. RTV the probe in position
to complete your installation.
4. Locate caution label directly above the alarm on the appropriate corner
cover.
Electrical Connections
1. Note the separate green wire that is routed with the low voltage power
supply lead wires (gray colored cable) that come from the power supply
module. Route the separate green wire to the outlet box on the hood that
powers the hood lighting fixtures. Route the green wire noted above into
the rear connector on this outlet box and connect to a secure earth screw
inside the outlet box. This green wire provides earth ground to the alarm
module to make it less susceptible to electrical noise created by the
fluorescent lights.
2. Route the power supply module AC voltage lead wires (black and white
wires) down between the fume hood liner and outside wall to the back of
the header panel. On standard Protector Fume Hoods, run this wiring
inside the header panel through the access hole provided in the right side
corner post. Remove the header panel cover plate to gain access for
specific wiring connections. Instructions for wiring connections for each
style of hood is as follows:
