Before you install your laboratory fume hood, you need
to prepare your site for installation. Carefully examine
the location where you intend to install your hood. You
must be certain that the area is level and of solid
construction. In addition, a dedicated source of
electrical power must be located near the installation
site.

Carefully read this chapter to learn:

• The location requirements for your installation
site.

• The support requirements for your installation
site.

• The exhaust requirements for your installation
site.

• The electrical power requirements for your
installation site.

• The service line requirements for your
installation site.

• The space requirements for your installation
site.

Refer to Appendix B: Protector ClassMate Dimensions
for complete fume hood dimensions.

Chapter 2: Prerequisites

Location Requirements

The Fume Hood should be located

!

away from traffic patterns, doors,
fans, ventilation registers, and any
other air-handling device that could
disrupt its airflow patterns. All
windows in the room should be closed.

Support Requirements

DO NOT locate the fume hood on a

!

cart, dolly, or mobile bench. ALL
Protector ClassMate installations
must be permanent and stationary.
The supporting structure usually
consists of a base cabinet and
chemically resistant work surface. See

Appendix D: Protector ClassMate
Accessories.

Exhaust Requirements

The exhaust duct connection has been designed for 8"
nominal pipe (8.625" O.D.) to allow for minimum static
pressure loss while operating at 100 fpm face velocities.
The 8" exhaust duct also allows for proper transport
velocities away from the hood in the 1000 fpm to 2500
fpm range. It is acceptable to combine the air from two
hoods with a transition coupling that would basically
have two 8" nominal exhaust inlets and one 12" (12.00"
O.D.) nominal exhaust outlet. See Appendix D
Protector ClassMate Accessories for transition
coupling. The proper exhaust volume and static
pressure loss are listed next for each hood model:

The following are instructions for mounting a 2 x 4
cross support:

1. Level the base cabinets and the work
surface.

2. Scribe a line on the wall or back of the base
cabinet to locate the support under the work
surface.

3. Mount the support by attaching it to the wall
or base cabinet.

4. Place the hood on top of the work surface
and cross support.

The work surface should be smooth and durable, and
made from a chemically resistant epoxy resin. The
surface should be nonporous and resistant to the acids,
solvents, and chemicals used in conjunction with the
Protector ClassMate Fume Hood. The work surface
should also contain a spillway for containing primary
spills.

See Appendix D: Protector ClassMate Accessories for
the work surfaces, and storage cabinets.

Chapter 3: Getting Started

The exhaust connection on your hood
has been designed for 8" nominal pipe
(8.62" O.D.) to allow for minimum static
pressure loss with proper transport
velocities away from the hood. It is
acceptable to combine the air from two
back to back hoods with a 12" x 8" x 8"
dual exhaust adapter that would
basically have two 8" nominal exhaust
inlets and one 12" (12.00" O.D.)
nominal exhaust outlet. See Appendix
D: Protector ClassMate Accessories for
dual exhaust adapter. Refer to exhaust
requirements in Chapter 3 Fume Hood
Components on exhaust volumes for
your model to properly size the blower.
Consult Labconco Sales Engineering
Team should you require help sizing
your blower for the exhaust volume and
total system static pressure loss.

Connecting the Electrical
Supply Source to the
Protector ClassMate Fume
Hood

Prior to connecting any electrical wiring to the fume
hood structure, refer to the hood identification plate for
the proper electrical characteristics of your specific
model.

!

WARNING: The building electrical supply
system for Protector ClassMate 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.

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 remote blower style Protector ClassMate Hood is
fully wired internally for 115 Volt, 60 Hz, 15 Amp
electrical service. The number of circuits varies
depending on the model. The Protector ClassMate
Hood models do not feature internal wiring or electrical
components excluding the fluorescent light assembly.
All of the hood’s electrical connections are terminated
at the internal boxes for hook-up by a qualified
electrician. The specific internal boxes for hook-up are
the lights, blower, and 115V, 60 Hz, 15A duplex
outlets. Refer to the wiring diagram for your Protector
ClassMate in Appendix C: Protector ClassMate Fume

Hood Specifications.

All wiring for the enclosure MUST be
performed by a licensed electrician
and conform to all local codes. In
most cases, the hood will require the
use of shielded conduit to protect the
wiring into the hood. The grounding
connection shall not be made to the
terminal box cover.

The fluorescent light has been mounted outside the top
liner panel assembly and is sealed from any vapors used
inside the hood structure. To change the fluorescent
light bulbs in your hood, you must first remove the
front panel from the hood. Next remove the screws
holding down the light reflectors. Remove the light
reflectors and slide them away temporarily.

The fluorescent light assembly is now fully exposed
and ready for service. While the fixture is in this
position, replace the defective bulbs, and reassemble.

Connecting the Service
Lines to the Protector
ClassMate Fume Hood

The hoods with service fixtures have been fully
plumbed for up to four valves on the hood for your
installation convenience. Supply tubing shall be
provided by the qualified contractor. Tubing is to
extend through the work surface to make connections to
the individual supply lines in your facility.

On standard models three of the fixtures are pre­plumbed using 1/4" copper tubing between the valve,
and hose connector. The upper right hand position
fixture is pre-plumbed using ¼" brass tubing between
the valve, and hose connector for use with natural gas.
