Chapter 5 - Maintenance
Maintenance Chapter Overview Introduction This chapter covers the routine maintenance procedures for the Haz-Dust EPAM-7500. In this chapter This chapter contains the following topics. Topic Checking the Calibration Span. (Optional Accessory). Checking the Flow Rate. Adjusting the Flow Rate. Battery Maintenance. Cleaning the Impactors Cleaning the Sensor Optics.
Checking the Calibration Span Introduction The Span Reference Insert Part Number CS-105 is a light scattering device that provides a constant value (termed a “k” factor). The Span Reference should be used as a reference to check factory calibration of the EPAM-7500 Monitor. When to check the calibration span The calibration span should be checked under the following conditions: • Once a month with normal usage. (Normal use is twice a week). • If the EPAM-7500 is dropped or otherwise damaged.
Checking the Calibration Span, Continued Checking Calibration Span Follow the steps in the table below to check the Span of the EPAM-7500 Monitor. Note: Failure to follow this procedure in its entirety may cause an incorrect “k” value reading. Step 1 2 3 5 6 7 Action Turn EPAM-7500 on. Press Monitor graphic. When the EPAM-7500 starts to begin monitoring, the instrument will run an auto zero one minute after beginning. Remove Auto Zero filter and impactor sleeve.
Checking the Flow Rate Introduction It is good technique to check the flow rate every time before and after a new gravimetric filter is used for sampling. Checking the flow rate Use the steps in the table below to check the flow rate. Notes: • When using an impactor, be sure the proper sampling inlet is attached to the sensor head. Step 1 2 3 Action Attach your airflow calibrator to the EPAM-7500 using the table below. If sampling... Then... PM-10, PM1. Attach one end of the calibration airflow 4.
Adjusting the Flow Rate Introduction The flow rate must be adjusted when it does not equal 2.0 LPM. Adjusting the flow rate Follow the steps in the table below to adjust the flow rate. 1 2 3 4 5 6 7 8 9 10 11 Press Settings from the main menu. Press the button until you are on the last screen. Press the Lock graphic to unlock the settings. Press the white box to enter the security code. Press HD7 on the keyboard. Press the Enter button on the keyboard. Press the Check Box next to the Force Pump On.
Battery Maintenance Introduction The battery pack is a 10.8-volt Li-Ion rechargeable battery. It is important to check the battery periodically and recharge when necessary. Checking the Battery The battery status can be checked from any screen on the EPAM-7500. The graphical icon is on the bottom middle of the screen. Recharging the battery Follow the steps in the table below to recharge the battery using the supplied charger. Note: If the battery is too low, the EPAM-7500 will turn off.
Battery Maintenance, Continued Removing and replacing the battery pack The battery pack can be removed and replaced whenever necessary. Removing the battery Follow the steps in the table below to remove the battery pack. Step 1 2 3 Action Loosen the two retaining pem screws from the top plate of the EPAM-7500.
Cleaning the Impactors Introduction Impactors should be disassembled and cleaned and greased at regular intervals. Example: You should clean impactors every thirtieth sample or once a month to start, but heavy loadings are observed on the target disk, as often as appropriate. Cleaning the Impactors Follow the Steps in the table below to clean the impactors. Step 1 2 Action Pushing with a pen from bottom remove the impactor through top of impactor sleeve into the palm of your free hand.
5 Put two or three drops of the solution on the impaction cup. The drops should saturate the disk, flowing freely to the edge. 6 Let the impaction cup “dry” by allowing the solvent to volatilize, leaving a thin film of grease on the impaction cup. 7 Replace the impaction cup onto the impactor jet. Re-insert the impactor into the impactor sleeve.
Cleaning the Sensor Optics Introduction Although the EPAM-7500 has an internal sensor purge it is important to keep the sensor optics of the EPAM-5000 clean to ensure the integrity of the optical sensor. The sensor optics needs to be checked every 2 months or on a weekly basis, when used in a 2 to 3 mg/m3 T.W.A. environment. Cleaning the Sensor Optics Follow the steps in the table below to clean the sensor optics. Figure 5-4. Picture of the cleaning kit.
Cleaning the Sensor Optics, Continued Step 1 2 3 Action Remove the screws located on sensor cover. Inspect internal sensor. Inspect cavities for residual dust. Blow the dust away with low-pressure air or wipe with foam tipped cotton swab. Inspect the glass lens covers for dust. Note: Use one of the following methods to clean the glass lens. • Blow the dust away with low pressure air, or, • Use a small amount of isopropyl alcohol and wipe with cotton swabs.
