The exhaust connection should be installed by a qualified
HVAC contractor.
The exhaust connection on your hood has been designed for 12" nominal pipe
(12.75" OD) to allow for minimum static pressure loss with proper transport
velocities away from the hood. Consult Labconco Customer Service should you
require help sizing your blower for the exhaust volume and total system static
pressure loss.
The selected exhaust duct material should match the hood
procedures and chemicals used to ensure compatibility.
Connecting the Electrical Supply Source
to the Protector XLE Fume Hood
Prior to connecting any electrical wiring to the fume hood structure, refer to the
hood identification plate for the proper electrical requirements of your specific
model.
WARNING: The building electrical supply system for
Protector XLE Hoods should include overload protection. A
switch or circuit breaker should be in close proximity to the
equipment and within easy reach of the operator. The switch
or circuit breaker is to be marked as the disconnecting device
for the equipment. Consult the NEC-2002 for proper
installation.
The identification plate, model number, serial number, and electrical connection
boxes are accessible from the front of the fume hood by removing the front panel.
The Protector XLE Hood is normally wired for 115 Volt, 60 Hz, 20 Amp or
230Volt, 50 Hz, 10 Amp electrical service. Check the I.D. plate behind the front
panel for voltage verification. The number of circuits varies depending on the
model. All of the electrical connections are terminated at the single point internal
junction box for hook-up by a qualified electrician. The single point internal
junction box is used for the connection of the lights, blower, and duplex outlets.
Refer to the wiring diagram for your Protector in Appendix C: Protector XLE
