Duracell 75 manual Routine Maintenance, Periodic Maintenance

2.Filter-equipped exhaust systems shall not be operated with filters removed.

3.The posted instructions for manually operating the fire extinguishing system shall be kept conspicuously posted in the kitchen and reviewed periodically with employees by the management.

4.Listed exhaust hoods shall be operated in accordance with the terms of their listings and the manufacture instructions.

5.Cooking equipment shall not be operated while its fire-extinguishing system or exhaust system is not operating or otherwise impaired.

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. This schedule may then be altered as needed after visual examinations of the collected material contained on the ionizing-collecting cells. Daily washing is not unusual for units operating on heavy welding fume, kitchen exhaust hoods or similar contaminants.

B.Detergent

Effective washing is dependent upon detergent. The detergent, as supplied by Trion, Inc., is formulated specifically for electronic air cleaners. 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 Air Boss controller (Optional) contains a digital LED display for kilovolt and milliampere readings. The milliammeter should be observed on a routine basis to be sure that it is reading within the prescribed operating range as marked on the data plate. For those units containing a voltmeter, the ionizer readings should be between 12.5 and 13.5 KV.

The ATS controller and remote PWM box both have LED indicating lights to show power to the PWM power supplies. Flickering or failed LED’s indicate electrical arcing and/or power failure.

5. Periodic Maintenance

A. Fire Suppression System (IF INSTALLED) –

Every 6 Months Properly trained and qualified personnel shall complete inspection, cleaning and servicing of the fire suppression system.

	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.
B.	Controller	-	Every 12 Months
	The inside of the controller cabinet should be
	examined for accumulated dirt and dust. If required,
	the components should be cleaned using a good
	brand of electrical contact cleaner. All terminal
	connections should be checked for securement and
	tightened or reworked as required.
C.	Ionizing-Collecting Cell –		Every 6 to 12 Months

Remove and inspect the ionizing-collecting cells for excessive dirt accumulations. Manually clean as required in a soak tank, commercial car wash, or with a pressure hose or pressure cleaner using a low pressure setting. At this time, particular care should be taken in cleaning each of the insulators.

WARNING:

DO NOT USE HIGH PRESSURE STEAM CLEANING EQUIPMENT TO CLEAN CELLS. THE EXCESSIVE HEAT AND PRESSURE WILL CAUSE THE PLATES TO WARP AND IN TURN POSSIBLY CAUSE EXCESSIVE ARCING.

D. Filter Devices –Every 4 to 6 Months

Hoods, impingers, metal mesh filters, ducts and other appurtenances shall be cleaned to bare metal at frequent intervals prior to surfaces becoming heavily contaminated with grease, oil or other contaminate. It may be advantageous to clean readily removable items, such as impingers, metal mesh filters or other permanent filter devices in a soak tank, with a pressure hose or pressure cleaner set low. After cleaning to bare metal, components shall not be coated with powder or other substance.
