Brief Description: ADJUSTING THE DOOR SEAL INFLATION
INFLATION OF THE DOOR SEAL IS CONTROLLED BY THE PRESSURE SWITCH IN THE DOOR SEAL PRESSURIZATION SYSTEM. THE PRESSURE SWITCH CAN BE ADJUSTED USING A SCREW LOCATED BETWEEN THE ELECTRICAL CONNECTION PRONGS. ADJUSTMENT IS DONE WITH THE DOOR INSTALLED ON THE AIRCRAFT.
STEPS 1. FROM INSIDE THE AIRCRAFTS, CLOSE AND LATCH THE DOOR. 2. ACTIVATE THE DOOR SEAL SYSTEM. 3. ADJUST THE PRESSURE IN TEH DOOR SEAL BY USING THE SET SCREW ON THE PRESSURE SWITCH. INCREASE OR DEREASE THE PRESSURE AS REQUIRED TO FORM A TIGHT SEAAL BETWEEN THE DOOR AND FRAME. A SWITCH SETTING THT CAUSES THE PUMP TO RUN MOMENTARILY APPROXIMATELY EVERY 15 SECONDS USUALLY PROVIDES A GOOD SEAL. DO NOT OVER-PRESSURIZE THE SEAL.
note: normally not more than 1/2 turn of the screw in either direction is required to provide adequate pressure in the seal.
