INTRODUCTION Thank you for purchasing a Cadexair hood Stadium.The Sadium serie hood is ULC and UL listed for use in a commercial kitchen exhaust system and Exhaust Cleaning Assembly for Kitchen Exhaust Duct, such as the following articles: ULC-S646 ULC-S647 The primary function of a Stadium Serie hood is to filter the grease, lint and dust particles and remove the odor from the exhaust air. - Page 3 Filter Removed: Should the bag or box filters be removed during normal operation the Cadexair Stadium unit is automatically shutdown. A pressure transducer measuring static pressure across the bag filters and box filters monitors a minimum pressure drop of 0.05” W.C. When the filter is removed the pressure differential falls and the pressure switch is activated.
- Page 4 replaced rotate the OVERRIDE SWITCH to counter clock wise to resume normal operation. MXFLOW OPTION INCREASING FILTER LIFE MXFLOW is designed to increase filter life while maintaining maximum exhaust volume during the commercial kitchen cooking operation. Immediately after commissioning the Stadium unit the exhaust air volume is at the highest level.
- Page 5 In the example above the “No MXFLOW” Stadium unit exhaust volume (shown in BLUE) gradually drops as the filters become increasingly clogged. Even when the prefilters and bag filters are replace the exhaust volume does not return to maximum because the box filter continues to clog.

WHEN TO CHANGE THE KES FILTERS The Prefilter, Bag filter and Box filter must be changed on a regular basis to maintain the high grease extraction efficiency required by the UL/ULC listing. Once a filter clogged light comes on the filter has reached its grease holding capacity. Further use will restrict exhaust air flow causing hood smoke capture problems and/or cause the clogged filter to blow out into the next filter or the exhaust fan. - Page 7 2. Determine the number of days between the Startup date and the Bag filter Change No. Actual date. Subtract two days from this number. Add the this number of days to the last actual bag filter change and enter this new bag filter schedule date in the schedule under Filter Change No.

The Flow % is a value that need to be set at the start-up in the CC50 or CC200 controller. To have your exact Max. Value, you need to multiply the Max Value when the Flow % = 100, with the real Flow % of the operational system. EX : Flow % = 3200 CFM/ 4000 CFM = 80 %. -
Page 10: Kes Maintenance Schedule
KES MAINTENANCE SCHEDULE Every two weeks: Consult the CC50 or CC200 screen to check the pressure reading for each type of filter and check the difference with the maximum pressure differential for each filter (see table of max pressure filter operation). It is very important to maintain clean prefilter(s). Replacing the inexpensive prefilter(s) often extends the life of the bag and box filters and reduces unnecessary down time due to clogged filter shutdowns. - Page 11 4. Inspect all electrical connections. Tighten if necessary. 5. Test the filter-removed circuit. Open the prefilter access door while the STADIUM unit is in operation. The unit should shut down and indicate a filter-removed condition. Every Six Months: 1. Complete the two-week, monthly and three month check list. 2.

Re-greasing of motors depends on the application and is best left to trained service technicians. 3. Periodically check if motor is running hotter then normal. Centrifugal Exhaust Fan: 1.
