General

IMPORTANT

Failure to perform certain procedures or note certain conditions may impair the performance of this

product. For maximum safety and optimal performance, please read and understand the Ventis MX4

Product Manual available online at the Ventis MX4 Resource Center at

www.indsci.com/ VentisMX4resources.

Personnel

CAUTION: For safety reasons, this equipment must be operated and serviced by qualified personnel only.

Read and understand the product manual completely before operating or servicing.

Hazardous Conditions, Poisons, and Contaminants

WARNING: Servicing the unit, replacing or charging batteries, or using the communications port must only

be done in an area known to be nonhazardous. Not for use in oxygen-enriched atmospheres.

WARNING: Power-off the monitor before servicing the unit or replacing the battery.

WARNING: Substitution of components may impair intrinsic safety and may cause an unsafe condition.

CAUTION: High off-scale readings may indicate explosive gas concentration(s).

CAUTION: Any rapid up-scale reading followed by a declining or erratic reading may indicate gas

concentration(s) beyond the upper scale limit which may be hazardous.

Silicone compound vapors or other known contaminants may affect the combustible gas sensor and cause

readings of combustible gas to be lower than actual gas concentrations. If the monitor has been used in an

Ventis™ MX4 Product Manual

area where silicone vapors were present, always calibrate the monitor before next use to ensure accurate

measurements.

General Usage

Oxygen-deficient atmospheres may cause combustible gas readings to be lower than actual concentrations.

Oxygen-enriched atmospheres may cause combustible gas readings to be higher than actual

concentrations.

Sudden changes in atmospheric pressure may cause temporary fluctuations in the oxygen reading.

Verify the calibration of the combustible gas sensor after any incident where the combustible gas content has

caused the monitor to display an over-range condition.

Sensor openings, water barriers, and the pump inlet must be kept clean. Obstruction of the sensor openings

or pump inlet and/or contamination of the water barriers may cause readings to be lower than actual gas

concentrations.

To avoid the potential of liquid being pulled into the sample tubing and pump assembly, it is recommended

that Industrial Scientific filter (P/N 17027152) be used on the sample tubing when drawing samples using the

aspirated monitor.

WARNING: INSERT THE ALKALINE BATTERIES WITH THE CORRECT POSITIVE “+” AND NEGATIVE “-“

ORIENTATION. WARNING: The Ventis MX4 is only approved for use with AAA battery types Energizer

EN92 and Duracell MN2400. Do NOT mix battery types.

WARNING: The use of leather cases can produce inaccurate readings with diffusion (non-aspirated) gas

detection instruments for specific monitoring applications. Leather cases should be used ONLY as carrying

cases, and NOT for continuous monitoring, with diffusion instruments configured to measure gases other

than O2, CO, CO2, H2S, and combustible gases (LEL/CH4).

Agency-issued Conditions of Use and Warnings

Ensure all part-use restrictions (e.g., battery) meet any agency-mandated conditions of use.

Ensure all instrument-configurable settings (e.g., always-on setting) meet any agency-mandated conditions

of use. When using instrument-compatible Industrial Scientific docking stations, maintain mandated settings

through the software (e.g., iNet Control or Accessory Software) or by manually configuring the instrument

settings after docking.

The Ventis MX4 is CSA certified according to the Canadian Electrical Code for use in Class I, Division 1 and

Class I, Zone 1 Hazardous Locations within an ambient temperature range of Tamb: -20°C to +50°C. CSA

has assessed only the %LEL combustible gas detection portion of this instrument for performance according

to CSA Standard C22.2 No. 152. This is applicable only when the monitor is used in the diffusion mode and

has been calibrated to 50% LEL CH4, and when the monitor is used in the aspirated mode with an Extended

range lithium-ion battery and has been calibrated to 50% LEL CH4.

CAUTION: CSA C22.2 No. 152 requires before each day’s usage, sensitivity must be tested on a known

concentration of pentane or methane equivalent to 25% or 50% of full scale concentration. Accuracy must

be within -0% to +20% of actual concentration. Accuracy may be corrected by referring to the

zero/calibration section of the Product Manual.

The equipment complies with the standards IEC 60079-29-1 and EN 60079-29-1 for methane, propane, and

hexane with the following exception: as for the methane (mine) detector, the battery run time was verified to

be seven (7) hours rather than the eight (8) hours recommended by the standards, respectively.

MED-certified instruments may be used only when configured and maintained to disallow power-off when

the unit is in alarm.

The Mine Safety and Health Administration (MSHA) has approved the Ventis MX4 as a Permissible Multi-

Gas Monitor with the following warnings:

Ventis™ MX4 Product Manual

•MSHA approved for use with either the P/N 17134453-X2, 3.7 volt, Lithium-ion battery or P/N

17148313-2, 3.7 volt, lithium-ion Extended battery only. The battery pack is not user-replaceable. The

monitor battery and the lithium battery on the main PCB are technician replaceable only. Charge

rechargeable lithium-ion batteries with an ISC battery charger designed for use with this monitor in fresh

air locations only.

•The monitor is to be calibrated according to the procedures in the instruction manual only.

•The aspirated version of the Ventis MX4 is only approved for use with the Extended range battery only.

•The monitor must display methane in the percent-by-volume mode (0-5%) for compliance

determinations required by 30 CFR Part 75, subpart D.

SANS 1515-certified units may be used only as follows:

•Diffusion applications

•Configured and maintained to disallow power-off when the unit is in alarm

•The Methane alarms are set as follows: low alarm = 1%vol and high alarm =1.4%vol

•With approved Lithium-ion batteries (see Ventis MX4 Accessories and Parts in this manual).

Recommended Practices

Industrial Scientific Corporation recommends the monitor be fully charged (when equipped with a

rechargeable battery), configured, and calibrated before first time use. If the lithium-ion battery is deeply

discharged, it can take up to an hour for the instrument display to indicate that the battery is charging.

Monitors used infrequently should be fully charged every four months.

No part of the unit should be covered by any garment, part of a garment, or other item that would restrict the

flow of air to the sensors or impair the operator's access to the audible, visual, or vibration alarms.

Industrial Scientific Corporation recommends a full monitor calibration be performed monthly (at a minimum),

using a certified concentration(s) of Industrial Scientific calibration gas(es) to help ensure monitor accuracy.

Industrial Scientific Corporation recommends the monitor be zeroed and bump tested before each use with a

certified concentration(s) of Industrial Scientific calibration gas(es).

Battery contacts are exposed on batteries when they are removed from the monitor. Do not touch the battery

contacts and do not stack batteries on top of one another.

When reassembling the instrument or installing a battery pack, maintain ingress protection by tightening

each fastener to its stated torque value (see the “Ventis MX4 Monitor three-Dimensional Diagram” and its

key in this manual).

Contact your service representative immediately if you suspect that the Ventis MX4 is working abnormally.

►Ventis MX4 Capabilities

The Ventis MX4 is a portable multi-gas monitor. Offered as a diffusion monitor, it detects and measures gas(es)

present in open space. To enable monitor use within confined space locations, the Ventis MX4 is also offered as an

aspirated monitor. A pump module and battery accessories enable the conversion of either monitor for dedicated use

in either confined or open spaces.

Based on the customer’s monitor order, up to four sensors are factory installed enabling the monitor to continuously

and simultaneously detect and measure the presence of up to four specific gases.

Equipped with a multi-mode (audible, visual, and vibration) and multi-level alarm system, the Ventis MX4 monitor is

capable of notifying its user of potentially hazardous gas concentrations.

The monitor performs continuous data logging at 10 second intervals. It can store approximately 90 days of data for a

four-sensor configuration. Its date- and time-stamped event log records and stores data for the following: 60 alarm

events, 30 error events, and 250 manually performed calibrations or bump tests. The memory, when full, overwrites

the oldest data as the newest readings and events are logged.

The Ventis MX4 monitor functions as an independent device to monitor the environment for hazardous gas

concentrations. It is compatible with products that charge, calibrate, bump test, read and record instrument data,

protect, and otherwise enable or enhance use of the monitor and its data. For a complete list of these products,
