vapors found inside of stand-alone chemical safety cabinets. The Vent-Box serves as a modular ventilation and
ltration system for all chemical safety cabinets. At the heart of the product line is the innovative Air Science
Multiplex™Filtration Technology that creates a safe work environment over the widest range of applications in
the industry.

II. Unpacking Your Vent-Box
This chapter aims to provide relevant information on how to handle the Vent-Box properly upon receipt.
Failure to follow these instructions may damage the unit. We strongly advise you to read this chapter carefully
before proceeding further.
2.1 Step-By-Step Procedure
1. Inspecting the Crate, Pallet, Boxes.
»Upon receipt of your new Vent-Box, inspect all cartons. If there is any visible damage to the exterior
please refer to Damaged Freight Claim Information on our website.
2. Moving the Pallet.
»The pallet is designed to protect the Vent-Box from any foreseeable circumstances. However, excessive
impact onto the boxes or pallet may also damage the unit. Prevent any direct impact or hitting to the
pallet when moving.
»When lifting the pallet, always ensure that the oor jack or mechanical lift truck has fully entered under
the pallet in order to achieve stability. Failure to do so will increase the risk of the pallet falling off the
oor jack or mechanical lift truck during handling. Please use a suitable extension bar when necessary
3. Opening the Boxes.
»If you did not receive one or more of the parts listed on the packing checklist, or if any of the items are
damaged, please refer to the Damaged Freight Claim Information on our website.
4. Removing the Packaging Material.
»The Vent-Box is protected by Styrofoam, cardboard and/or shrink-wrap.
»If you nd any damage during this stage of unpacking please refer to the Damaged Freight Claim
Information on our website.
»We recommend leaving the unit secured with straps to the pallet until located in its approximate nal
position to facilitate ease and safety in handling.
Note: Choosing the best location for your Vent-Box in order to achieve optimum operating perfor-
mance is determined by a number of factors. Please refer to the next chapter for some guidelines.

5. Moving the Vent-Box.
»When lifting the pallet with the Vent-Box, always ensure that the oor jack or mechanical lift truck has fully
entered under the pallet. This is to increase stability and reduce the risk of the unit falling down. Please
use a suitable extension bar when necessary. During the moving of the Vent-Box, ensure there is enough
distance between the supports of the pallet and the ground. Dragging the pallet against the ground will
damage the pallet and possibly your new unit.
»When removing unit from pallet or placing onto pallet, use at least two people.
6. Removing the Strapping.
»Remove the strapping by cutting it at a safe position to prevent any scratching the surface of your
new Vent-Box.
»Do not discard the packaging material until you have checked all of the components, installed and
tested the unit.
Note:
»When installing the Vent-Box onto an existing work surface, ensure that the structure can safely support
the combined weight of the unit and any related equipment. Some modications to the work surface may
be necessary.
»The work surface should be smooth, non-porous and resistant to the disinfectants and chemicals used in
conjunction with the Vent-Box.

III. Installing Your Vent-Box
3.1 Choosing a Suitable Location
Location impacts the nature and extent of external airow disturbances, which may affect performance
of the Vent-Box when it is exposed to these disturbances.
When installing the unit, it should be located as far away as possible from sources of airow disturbance and in
an orientation which optimally shields the airow of the Vent-Box from all external airow disturbances. Please
note that the unit should not be placed close to another unit.
Please follow these guidelines when choosing a suitable location for your Vent-Box:
• The location must be far away from:
»Personnel trafc ows.
»Air vents (in and out).
»Doors and windows.
»Any other sources of disruptive air currents or air drafts.
• If drafts or other disruptive air currents exceed the face velocity of the lter, the potential exists for
contaminated air to enter the work zone of the Vent-Box.
• A minimum distance of 50 cm (20 in) to the top of the ceiling is recommended for blower changing
purposes.
• A clearance of 183 cm (6 ft) in front of the unit is strongly advised in order to maintain proper airow.
• Please permit adequate space for cleaning behind the Vent-Box.
• Unit is for xed installation.
3.2 Environmental / Electrical Conditions
The equipment is designed to be safe for at least the following conditions:
»Indoor use.
»Altitude < 2,000 m (6,562 ft).
»Temperature range 5ºC to 40ºC (41ºF to 104ºF) ambient.
»Relative humidity <80% up to 31ºC (88ºF) decreasing to <50% at 40ºC (104ºF).
»UL Installation Category II.
»UL Pollution Degree 2.
»Continuous operation.
»Electrical supply tolerance of –10% / +10%.
»120VAC, 60Hz, 10A or 230VAC, 50Hz, 5A.
»Fuse: 250V, 10A, Time Lag Low Breaking for 120VAC or Fuse: 250V, 5A, Time Lag Low Breaking
for 230VAC.
»Always ensure unit is connected to a reliable and properly grounded receptacle.
»Appliance inlet on this device is the disconnect device; appliance should not be positioned so that it is
difcult to operate it.

Power Cord:
»1) For units intended to be operated at 120 volts (North America): Use a UL-listed and CSA-certied cord
set consisting of a minimum 18 AWG, Type SVT or SJT, three-conductor cord, a maximum of 15 feet in
length and a parallel blade, grounding-type attachment plug rated 15 amperes, 125 volts.
»2) For units intended to be operated at 230 volts: Use a cord set with a grounding-type attachment plug.
The cord set should have the appropriate safety approvals for the country in which the equipment will be
installed.
3.3 Installing Your Vent-Box
1. Please refer to Unpacking Your Vent-Box - page 5.
2. Inspect your unit carefully. Should you nd any defect please refer to the our Legacy Warranty.
3. Wipe down the interior and exterior of the unit with water or a mild household detergent.
4. Connect Vent-Box to the main power supply and turn on the blower. Each unit requires its own
dedicated 13A (230V) or 15A (115V) power outlet which should not be shared with other appliances.
WARNING! Do not move the unit without observing the following precautions:
• Observe the necessary precautions when relocating the Vent-Box, as it is heavy.
• Warning - Tipping Hazard. Pushing high up on the unit may cause system to tip over. Be careful when
moving. Move with assistance only.

3.4 Set Up
1. Unpack the Vent-Box unit. In most cases the unit is
shipped with lters pre-installed at the factory.
2. Place the unit on the workbench in location
required. Please allow a minimum clearance of 6
inches (150 mm) between the right-hand side of the
unit and any adjacent wall to allow the detachable
power supply cord to be disconnected from the
power source.
3. Plug the unit into appropriate grounded wall
socket.
4. Install suitable chemical resistant hose from the
Vent-Box ange to the storage cabinet upper side
opening/vent port outlet. Note, the Vent-Box has
several ports to install the ange. Make sure that
the hose connection is tight. Hose clamps can be
used to hold hose in place.
5. Unscrew the lower cabinet vent port to allow
airow into the cabinet. Leave ame arrestors
installed.
6. If required, unit operation mode can be changed
from ductless to vented by optional duct connector
that is mounted over the exhaust air discharge.

3.5 Performance Validation / Certication
After installation and prior to use, product performance must be validated and certied to factory standards.
The following tests should be performed:
Airow Velocity
The testing methods and equipment required are specied on the test report. It is recommended that these
tests be performed only by a qualied technician who is familiar with the methods and procedures for certify-
ing these types of units.
3.6 Importance of Performance Validation / Certication
An airow velocity value that falls below the value specied inside the test report will not provide adequate
operator protection.
3.7 Disclaimer
The performance of the Vent-Box, while rigorously evaluated at the factory, cannot be guaranteed after transit
and installation. Therefore, on-site testing is always recommended.
