Trion 147207-001, Air Boss ATS manual Routine Maintenance, Preventative Maintenance

Some dirt is more tenacious than others to remove and may require a stronger detergent solution. Average settings have been factory set. Best possible settings for any given installation, however, are determined through experience. Determination can be made by visually examining the collecting elements after the first few washings.

To adjust the volume of detergent used within the given time setting, loosen the knurled knob with an Allen wrench on the control valve located in the by-pass line. Refer to the Detergent System Outline, Figure 4. Turning the knob clockwise increases the volume and counter clockwise decreases the volume. When adjustment has been made, be sure to retighten the setscrew.

4. Routine Maintenance

A.Washing Frequency

The frequency that the collected dirt is to be washed from the unit depends upon the type and amount of dirt in the air to be cleaned. Dirt, which is greasy in nature, tends to harden after collection and should be washed away often. Likewise, units operating under extremely heavy dirt loads should be washed more often as a large build-up of collected material will have a tendency to “blow-off” if permitted to remain on the collecting elements for long periods of time. In that the type and amount of dirt varies geographically (and from one location to another in any given area) it is recommended to start operation with a washing frequency of at least once a week, for most applications except kitchen exhaust. Kitchen exhaust applications should be washed daily. Schedules may then be altered as needed after visual examinations of the collected material contained on the ionizing-collecting cells. Also, daily washing is not unusual for units operating on heavy welding fume, kitchen exhaust hoods or similar applications.

B.Detergent

Effective washing is dependent upon detergent. The detergent reservoir should be examined on a routine basis; a minimum tank level established and never permitted to empty. An empty tank not only means poor washing, but can also be detrimental to the pump. The inside of the tank should be kept clean, free from dirt and foreign objects. The detergent as supplied by Trion, Inc., is formulated specifically for electronic air cleaners and should not be diluted when charging the tank. If substitutes are used, they must be approved by Trion, so as to not void the warranty and should be safe for use in ventilation systems and non-caustic, as 95% of the ionizing-collecting cells are constructed of aluminum and special high voltage insulation and gasket seals.

C.Electrical Operation

The front panel of the control contains indicating lights for the power supplies, one or two depending on the size of the ATS unit. The lights should be observed on a daily basis to ensure that the electronic air cleaners are operating.

5. Preventative Maintenance

A.Washing frequency – as required.

The washing schedule and detergent reservoir level as outlined under routine maintenance is again referenced here as excessively large contaminant buildup on the collecting elements invites down time. Established routine washing is a preventative maintenance requirement. The frequencies suggested below should be altered if necessary.

B.Fire control system - Every 4 to 6 months or as required.

Inspection, cleaning and servicing of the fire extinguishing system and all listed exhaust hoods shall be completed by properly trained and qualified personnel. For a fire control system supplied with the ATS unit refer to Figure 7.

All actuation components, including remote manual pull stations, mechanical or electrical devices, detectors, fire-actuated dampers, etc., shall be checked for proper operation in accordance with the manufacturers listed procedures. In addition to these requirements, the specific inspection requirements of the applicable NFPA standard shall also be followed. If required, certificates of inspection and maintenance shall be forwarded to the authority having jurisdiction.

C.Grease removal devices and components – every 4 to 6 months

Hoods, impingers, metal mesh filters, ionizing- collecting cell(s) fan, ducts and other appurtenances shall be cleaned to bare metal at frequent intervals prior to surfaces becoming heavily contaminated with grease or oily sludge. It may be advantageous to clean readily removable items, such as impingers, metal mesh filters, ionizing-collecting cell(s) or other grease removal devices in a soak tank, with a pressure hose or pressure cleaner. After cleaning to the bare metal, components shall not be coated with powder, oils or other substance.

When a cleaning service is used, a certificate showing date of inspection and/or cleaning should be maintained on the premises. Areas not cleaned will be noted.

Flammable solvents or other flammable cleaning aids shall not be used.

At start of cleaning process, electrical switches that could be accidentally activated shall be locked out. Components of the fire suppression system shall
