equipped with a HEPA filter.In the Class I configuration, the NU-813 provides personnel protection for handling low risk
aerosols and particulate matter.Room air enters the Enclosure, flowing past the operator into the work access opening
providing an air barrier which minimizes contaminants generated within the enclosure work zone from migrating into the
room. The air flows through the enclosure carrying contaminants with it, exiting through a HEPA filter.
1.2 Safety Instructions
These safety instructions describe the safety features of the LabGard® Model NU-813.
The CVE has been manufactured using the latest technological developments and has been thoroughly tested before
delivery. It may, however, present potential hazards if it is not used according to the intended purpose or outside of
operating parameters. Therefore, the following procedures must always be observed:
•The CVE must be operated only by trained and authorized personnel.
•For any operation of this unit, the operator must prepare clear and concise written instructions for operating and
cleaning, utilizing applicable safety data sheets, plant hygiene guidelines, and technical regulations, in particular.
oWhich decontamination measures are to be applied for the cabinet and accessories
oWhich protective measures apply while specific agents or materials that are used

3.0 Warranty
Details regarding product warranties can be found in the published warranty data separate from this manual and included
within the data packet sent with the unit.
4.0 Shipments
NuAire takes every reasonable precaution to assure that your LabGard® CVE arrives without damage. Motor carriers are
carefully selected and shipping cartons have been specially designed to insure your purchase. However, damage can occur in
any shipment and the following outlines the steps you should take on receipt of a NuAire LabGard® CVE to be sure that if
damage has occurred, the proper claims and actions are taken immediately.
4.1 Damaged Shipments
4.1.1 Terms are factory, unless stated otherwise. Therefore, it is important to check each shipment before acceptance.
4.1.2 If there is visible damage, the material can be accepted after the driver makes a notation on the consignee's copy
of the freight bill. Then an inspection must be made to verify the claim against the carrier. This inspection is the
basis of your filing the claim against the carrier.
4.1.3 If concealed damage is found, it is absolutely necessary to NOTIFY THE FREIGHT AGENT AT ONCE, and request an
inspection. Without this inspection, the transportation company may not accept a claim for loss or damage. If the
carrier will not perform the inspection, an affidavit must be prepared stating that he was contacted on a certain
date and that he failed to comply with the request. This along with other papers in the customer's possession will
support the claim.

5.0 Installation Instructions
5.1 Location
Within the laboratory, pharmacy, etc., the ideal location of the CVE is away from personnel traffic lanes, air vents (in or
out), doors and/or any other source of disruptive air currents.
If drafts or other disruptive air currents exceed the intake velocity of the cabinet through the access opening, the potential
exists for contaminated air to exit the cabinet. It depends on the severity of the air current. REMEMBER: A CONTAINMENT
CABINET IS NO SUBSTITUTE FOR GOOD LABORATORY TECHNIQUE.
Where space permits, a clear 6 inch (152mm) area should be permitted on each side of the enclosure for maintenance
purposes. The electrical outlet into which the CVE is connected should be readily accessible for maintenance purposes.
Do not position the cabinet to prevent access to the power cord. The power cord plug serves as the disconnect and
should remain readily accessible. If the outlet is inaccessible, such as a conduit (hardwired) connection, then an
appropriate warning label should be applied near the cabinets on/off switch to indicate the circuit breaker on the power
distribution panel to be used.
5.2 Electrical Services
The NU-813 Series CVE may be "hardwired" (optional) or connected via an electrical power cord which is standard. The unit
requires 115 VAC, 60 Hz or 230 VAC, 50 Hz depending upon model, single phase (current rating varies per cabinet size,
reference Electrical/Environmental Requirements). It is recommended that power to the unit be on its own branch circuit,
protected with a circuit breaker at the distribution panel.
Note: THIS UNIT CONTAINS ELECTRONIC BALLASTS FOR THE LIGHTING. ELECTRONIC BALLASTS
OPERATE WITH HIGH INRUSH CURRENT. IT IS NOT RECOMMENDED TO USE THIS PRODUCT WITH
GROUND
FAULT CIRCUIT INTERRUPTERS (GFCI'S) BECAUSE THE BALLASTS MAY CAUSE THE GFCI TO TRIP.
5.3 Final Assembly
REMOVE THE PROTECTIVE CARDBOARD COVER OVER THE EXHAUST OUTLET. The exterior surfaces are easily cleaned with
any mild household detergent cleaner using a soft cloth. Harsh chemicals, solvent-type cleaners and abrasive cleaners
should not be used.
Cabinet interior walls or work surface are easily cleaned with any mild household detergent cleaner using a soft cloth.
Turn the CVE on and let it operate for 60 minutes before using.

5.4 Certification Testing Methods and Equipment
After installation and prior to use, NuAire recommends that the CVE be certified or commissioned to factory standards. At
a minimum, the following tests should be performed.
1. HEPA filter leak test
2. Inflow velocity test
3. Airflow smoke patterns
The testing methods and equipment required are specified on the factory inspection report included with this manual (see
insert in back cover).
IT IS RECOMMENDED THAT THESE TESTS BE PERFORMED BY A QUALIFIED TECHNICIAN WHO IS
FAMILIAR WITH THE METHODS AND PROCEDURES FOR CERTIFYING LABORATORY CONTAINMENT EQUIPMENT
(SEE INSERT).
AFTER THE INITIAL CERTIFICATION, NUAIRE RECOMMENDS THAT THE CABINET BE RECERTIFIED AT A
MINIMUM ON AN ANNUAL BASIS AND AFTER EVERY FILTER CHANGE OR MAINTENANCE ACTION OR
ANY TIME THE OPERATOR FEELS IT IS NECESSARY.
Note!LabGard® CVE filters and seals provide premium performance; Quality Control in both design and
manufacturing assure superior reliability. However, protection to both product and operator is so vital that
certification to the performance requirements should be accomplished as stated to ensure safety
established by the factory standards.
