Introduction
Welcome to the Apex Premier Fume Hood Monitor Installation, Operation and Maintenance Manual. The
Apex Premier Monitor (APM) has been designed to provide accurate and reliable real-time monitoring of
fume hood face velocity on a wide variety of fume hoods including; variable air volume, constant air
volume, and high performance - low flow.

The revolutionary touch screen display allows the technician to easily calibrate and configure the APM
with no external tools or interfaces, yet remains completely invisible to the operator. Password protection
is utilized to prevent any unauthorized personnel from changing calibration or configuration items.
The APM utilizes 3 front-mounted push buttons that allow the operator to mute the alarm horn, enable
purge mode, and also view the internal settings of the APM. The mute and purge push buttons can also
be disabled if not required.
NOTE: The protection and performance provided by the APM may be impaired if used in a manner
not specified or contained in this manual.

Important Considerations
Prior to installing and calibrating your Accutrol APM , reference ANSI/ASHRAE STANDARD 110-
1995 for proper methods of testing performance of laboratory fume hoods.
Per ASHRAE guidelines, “The performance of a laboratory fume hood in providing protection for the
worker at the face of a hood is strongly influenced by the aerodynamic design of the hood, the ventilation
of the laboratory room, and by other features of the laboratory in which it is installed.”
The following items are identified by ASHRAE as being important factors contributing to the safe
operation of laboratory fume hoods:
1. Cross-drafts. Air currents may, by creating turbulent air pockets, draw contaminants from the hood.
Such cross-drafts could be caused by air supply diffusers or grilles, open windows or doors, or rapid
movements of people in front of the hood.
2. Work procedures. There is substantial evidence to suggest that all work in a hood should be
conducted as far back in the hood as practical. Typically, users have standardized the requirement that
all work should occur at least 6 inches behind the face of the hood. However, significantly improved
protection can be achieved by working farther than 6 inches from the face of the hood.
3. Internal obstructions. The location of too much laboratory equipment (bottles, glass, etc.) in the hood
will disturb airflow patterns into the hood.
4. The procedure being performed. The intrinsic hazard of the procedure being performed can affect
the level of safety required by the user.
5. Thermal challenge. Heat produced in the hood can cause significant disturbance in the hood
performance and even cause leakage of warm and possibly contaminated air from the top of the hood or
from behind the sash.
6. Rate of response. The transient state or interval required for a variable-air-volume hood to respond to
a rapid opening of the sash, or the time interval required for a hood to respond to a change in static
pressure in the main exhaust duct serving multiple hoods, may affect hood performance.

Standard Installation
Step 1: Choosing a Suitable Location
Care must be observed when choosing a suitable location for the APM if the internal reference is being
utilized (typical install). Locate a position on the fume hood pillar that is free from piping, electrical conduit
or obstacles. The APM requires at least 4” (10.2cm) of depth behind it for tubing and wiring clearance.
Care must be taken to stay away from external air influences such as air registers, diffusers, equipment
cooling fans, cross drafts, doors, windows, or anything influencing air flow. Reference Appendix K for
other available mounting options.
Figure 3 shows a typical location for mounting the APM. When possible, always install the APM above
the maximum height of the sash pane bottom to decrease the chances of a cross draft across the face of
the APM and into the fume hood.

Figure 3, Typical Fume Hood Installation Location
Step 2: Cutting the Mounting Hole
Use the template provided to aid in finding the best location (see Appendix A). Cut along the inner
dashed dimensions of the template and drill the two pilot holes. Slip the APM into the cutout to test fit the
unit and confirm the depth is correct. Do not attach the unit to the hood until all electrical connections and
the hood probe and tubing have been installed. Once all connections have been completed, use the two
screws provided to permanently mount the APM to the fume hood.
Step 3: (Optional) Locating the External Reference Probe
If the APM was ordered from the factory with an external reference probe in lieu of the internal reference,
observe the same precautions in choosing a good location for the external reference as previously stated
in step 1. Typical good locations are on the side of the hood casing or on the front pillar, above operator
height to avoid cross drafts developed by moving quickly in front of the hood.
Warning: Do not install the reference probe in a location that is not common with the hood to which it is
measuring. Unacceptable locations include; closets, inside the base cabinet, inside the hood chase,
corridors, ceilings, etc. Always keep the tubing length to a minimum (less then 5 feet) when possible.
Exercise care so tubing does not become kinked or pinched due to installation or moving internal parts of
the sash.

Standard Installation
Step 4: (Optional) Installing the External Reference Probe
Once a suitable location has been selected for the Room Reference Probe, drill a 7/16” diameter (11mm)
hole for mounting probe. Referencing Appendix D, feed the supplied clear tubing connected to the probe,
through the drilled hole. Carefully push the tubing over the room reference port located on the rear of the
APM enclosure (refer to Appendix B). Press the room reference probe firmly to seat properly into
location. Note: various sealants can be used but are not required.
Step 5: Locating the Hood Probe
The hood side wall probe is best located on the same side of the fume hood as the APM to keep tubing
length to a minimum. Due to the wide variety of fume hood types and configurations available, there is no
single standard hood probe location that will work for all fume hoods manufactured. Typical hood probe
locations are approximately 4” to 10” (10.2cm to 25.4cm) back from the rear of the sash panel and
approximately 2” to 8” (5.1cm to 20.3cm) above the highest vertical opening of the sash. Refer to Figure
4 for a diagram of approximate locations. If possible, contact the fume hood manufacturer for
optimum side wall probe location guidelines.

Step 6: Installing the Hood Probe
Once a suitable location has been selected for the Hood Probe, drill a 7/16” diameter (11mm) hole in the
side wall of the fume hood. Note: Reference fume hood manufacturer recommendations for best
method for drilling hood sidewall. Referencing Appendix D, feed the supplied clear tubing through the
drilled hole and carefully push it over the sensor port located on the rear of the APM enclosure (refer to
Appendix B). Press the hood probe firmly to seat it properly into the side of the fume hood. Note: various
sealants can be used but are not required. Contact the fume hood manufacturer for acceptable sealant
types and information.
