[Refer to fig. 21]

Grease extractor modules are installed by sliding the top [narrow] part of the module into the upper retaining slot and then lowering the bottom part of the module into the grease trough slot.

NOTE: Handle faces towards capture area.

2.Grease Receptacles

Grease receptacles are located at each end of each ventilator section. These must be cleaned out periodically. The frequency of this cleaning is dependent upon the type of equipment used beneath the ventilator and the duration of its use. It is suggested that initially the grease receptacles be emptied daily.

C.Auto Wash Grease Extractors [AW

Models]

These type ventilators have an automatic wash cycle which requires only occasional wiping down of inside grease extractor.

1. Grease Extraction Chamber

The front panel is hinged to facilitate access to the nozzles and grease extraction baffles.

[Refer to fig.22]

fig. 22

To open, turn all front panel latches clockwise to the open [unlatched] position and swing the bottom of the front panel out. "Kickstands" are provided at each end of the

ventilator section to hold the front panel open.

2. Spray Nozzles

Spray nozzles for hot water wash and cold water mist are protected from clogging by wye-strainers located in the plumbing enclosure. However, scale and contaminants will accumulate in time and these will require occasional cleaning to assure proper wash down and spray distribution. A paper clip or other pointed object should be used to scrape contaminants from the nozzles.

D. Air Adjustment Baffle [Refer to fig. 23]

Some grease extractor models may be equipped with air adjustment baffles at the exhaust intake slot. These baffles may be adjusted to increase or decrease the intake slot, according to the cfm desired or required for varying pieces of cooking equipment underneath. The length of the baffles varies according to project design specifications and conditions. The standard opening of nominal 3" yields approximately 250 cfm/linear ft. and is used for most cooking appliances. Air flow may be reduced to a low as 150 cfm/linear ft. for ovens, steamers, etc. depending on local job conditions. Adjusting the slot to nominal 1-3/4" opening will yield approximately 150 cfm/linear ft.

The Thrift Island Series ventilators uses only one grease extraction chamber and is designed for 250-270 cfm/linear ft. on the cooking side and 150 cfm/linear ft. on the oven/steamer side. These units are provided with air adjustment baffles to "fine-tune" the balance of air from each side, and to change air velocity as job conditions dictate.
