Before you install the Procedure Station, you need to prepare the site for
installation. Carefully examine the location where you intend to install the
cabinet. 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:

• Location requirements.

• Electrical power requirements.

• Exhaust requirements.

• Service utility requirements.

• Space requirements.

Refer to Appendix C: Specifications, for complete electrical and environmental
conditions, specifications and requirements.

Space Requirements

The dimensions for the different models are shown in Appendix B:
Dimensions.

Clearance

Procedure Stations that exhaust their filtered air back into the room should
have at least six inches (150 mm) clearance from any overhead obstructions
when the cabinet is in its final operating position. A clearance of at least 6
inches (150 mm) should be maintained on both sides of the cabinet, as well as
12 inches behind the unit.

Chapter 2: Prerequisites

Service Line Requirements

All utility service lines should be ¼ inch O.D., brass, copper, or stainless
steel, and equipped with an easily accessible shut-off valve. If the service
line pressure exceeds 100 PSI, it must be equipped with a pressure regulator
to reduce the line pressure.

Note: The use of flammable gases or solvents should be avoided in the
Procedure Station. Open flame in the cabinet will disrupt the laminar airflow
in the cabinet and may damage the HEPA filters. Flammable gases or
solvents may reach explosive concentrations in the cabinet or ductwork. If
you feel that the procedure requires the use of an open flame or flammable
materials, contact the institution’s safety office.

The use of air or gases under high pressure should be avoided as they may
seriously disrupt the airflow patterns in the cabinet.

these instructions are missing or unclear, contact Product Service at 800-821­5525 or 816-333-8811.

Installing the Procedure Station on an Existing
Work Surface

Note: The Procedure Station is very top heavy. Use caution when lifting or
moving it.

When installing onto an existing work surface or benchtop, ensure that the
structure can safely support the combined weight of the cabinet and any
related equipment. The work surface should be at least as wide as the cabinet
and 31 inches deep to properly support the unit.

The work surface should be level, smooth and durable. The surface should
be nonporous and resistant to the disinfectants and chemicals used in
conjunction with the Procedure Station. This will allow a proper seal to form
between the bottom of the cabinet and the work surface.

A hole or notch may be cut in the supporting surface in the right front corner
to accommodate the optional drain valve.

Installing the Cabinet on a Labconco Base Stand

Labconco offers accessory Base Stands in a variety of configurations to suit
the particular needs. Stands can be ordered with adjustable telescoping legs
or with a manually or electrically adjustable hydraulic lift.

Chapter 3: Getting Started

Note: When moving the cabinet on the hydraulic lift base stand, ensure that
the hydraulic lines and the electrical cord are clear before installing the
cabinet on the stand or operating the lift system.

Connecting the PuriCare Cabinet to Utility
Service Lines

The service lines (if any) should be connected to the tube fitting(s) on the
outside of the liner wall as shown in Figure 3-3. To install the tubing, follow
these steps:

1. Ensure that the tubing is ¼ inch O.D., soft metal, and that the end has
been deburred completely.

2. Route the tubing from the rear of the cabinet, ensuring that it will line up
with the slot in the back of the side panel.

Note: Make sure that the tube routing will not contact any electrical wires.
DO NOT loop service line tubing within the side panels of the Procedure
Station.

3. Make sure that the nut on the tube fitting is loose, but do not remove it.
Look inside the fitting to make sure the tube ferrule is there.

4. Push the tube into the fitting until it is properly seated. The tube will go
approximately ¾ inch into the fitting.

5. Tighten the tube fitting nut hand tight and then, using a 7/16-inch wrench,
tighten it at least ¾ turn more.

6. Close the service valve in the cabinet and then slowly open the shutoff
valve on the service valve. Test all fittings for leakage. Tighten the tube
nut slightly if needed.

Optional Exhaust System Connections

All Procedure Stations are shipped to recirculate their HEPA filtered exhaust
air back into the laboratory.

Certain applications such as working with odorous products or volatile toxic
materials will require the connection of the Procedure Stations to an exhaust
system.

Note: The canopy connection, also referred to as a thimble or air gap
connection, allows single or multiple biohazard cabinets to be connected to
an exhaust system. During operation, the exhaust system draws all of the
cabinet’s exhaust air, plus a volume of room air (through the slots in the
canopy) into the exhaust duct. Canopy connections function as a “shock
absorber” allowing the system to function properly during changes in room
air pressure.

For information on selecting a canopy connection, go to Chapter 7:

Accessorizing the Cabinet.

Warning: If the research involves the use of toxic compounds or volatile
materials, contact the facility’s safety officer or Labconco to ensure that the
Procedure Stations and its exhaust system are compatible with the materials
you will be working with.

Drain Valve Installation

In order to prevent damage during shipping, the drain valve assembly has not
been installed. If desired, the valve should be installed after the cabinet is in
its final location.

To install the valve assembly, follow these steps:

Note: The work surface is heavy. Use caution when handling it.

1. Lift the work surface out of the Procedure Station by lifting on the knobs
at the front of the work surface. Steady the work surface while pulling it
straight out the front of the cabinet.

2. Using a putty knife, remove and discard the stainless steel cover that is
sealed over the drain mounting holes. Scrape out remaining sealant that
is around the holes.

3. Apply a light coating of silicone sealant (user supplied) to the mounting
surface of the drain assembly. Attach the drain assembly under the
bottom of the cabinet as shown in Figure 3-4. Wipe off any excess sealant
from the cabinet bottom. Ensure that the center drain hole is
unobstructed.

4. Make sure the drain valve is in the closed position.

Initial Certification

Prior to use, a qualified certifier should certify all Procedure Stations. Under
normal operating conditions, the Procedure Station should be recertified at
least annually and when relocated or serviced. The certifier should perform
the following tests, as recommended in ANSI/NSF International Standard
Number 49 in effect when the cabinet was manufactured:

• Downflow Velocity Profile Test

• Inflow Velocity Test

All PuriCare Series Procedure Stations operate using the following
principles:

• Filtration and retention of particulates by High Efficiency Particulate

Air (HEPA) filter(s)

• Laminar airflow

• Directional airflow

The major components are:

• The HEPA filter(s)

• The motor/blower to force air through the cabinet

• Cabinet air intakes (grilles), ductwork and air balance controls

HEPA Filters

HEPA filters are disposable, dry-type particulate filters. The filter material or
media is typically made of borosilicate microfibers formed into a thin sheet,
in a process similar to the production of paper. This sheet is folded, or pleated
to increase its surface area. The pleats are held in place by aluminum
diffusers or by beads of glue that add rigidity to the media pack. The pack is
then set into a frame, and sealed as shown in Figure 4-1.

The HEPA filter manufacturer establishes the efficiency of the filter by
challenging it with an aerosol of known particle size. The number of particles
that penetrate the filter are quantified, and this establishes the efficiency of
the filter. Thus, the filters used in the PuriCare Series Procedure Stations are
at least 99.99% efficient in removing particles 0.3 micron.
