Chapter 2: Prerequisites
Electrical Requirements
Other than explosion proof models, the Fiberglass 30
Hood models feature internal wiring for the
incandescent light assembly, light switch and blower
switch. If your unit has an integral blower, then
internal wiring to the blower motor and blower switch
is included. Explosion Proof blowers require on site
wiring. All internal wiring is terminated at the single
point wiring junction box for hook-up by a qualified
electrician. Refer to Chapter 3: Getting Started and
Appendix C: Fiberglass 30 Specifications for the wiring
diagram for proper electrical installation.
Service Line Requirements
All service lines to the laboratory fume hood should be
¼ inch outside diameter, copper (brass for natural gas),
and equipped with an easily accessible shut-off valve,
should disconnection be required. If the service line
pressure exceeds 40 PSI, it must be equipped with a
pressure regulator to reduce the line pressure. Please
check with local codes for other requirements.
Space Requirements
The dimensions for the different models are shown in
Appendix B: Fiberglass 30 Hood Dimensions.
