Original instructions
Proper Radioisotope blower selection can be determined from these exhaust
requirements and the total system static pressure loss. Contact Labconco
Customer Service for assistance in sizing a blower system.
Filter Pack Requirements
Contact your local EPA or NRC office to determine if exhaust filtration is
required. If required, these filter packs should be located as close as possible to
the hood to expose as little of the ductwork system as possible to the
radiochemicals being filtered. Consult your Safety Officer directly for specific
filter ratings on radiochemicals being used.
Electrical Requirements
The Protector Hood models feature internal wiring for the fluorescent light
assembly and light switch. All internal wiring is terminated at the single point
wiring junction box for hook-up by a qualified electrician. The blower switch,
and light switch wires are also terminated at the single point wiring junction box
for hook-up by a qualified electrician. Refer to Chapter 3: Getting Started and
Appendix C: Protector Radioisotope Specifications for the wiring diagram for
proper electrical installation.
