2.6 Positioning of the ADTS 505
WARNING: IN AN ENCLOSED AREA WITH FUEL VAPOUR PRESENT THIS EQUIPMENT MUST BE
PLACED AT LEAST 0.5 METRES ABOVE FLOOR LEVEL. THIS EQUIPMENT CONTAINS A
D.C. MOTOR WITH BRUSHES THAT COULD CAUSE A SPARK.
C
AUTION:TO OPERATE, PLACE THE UNIT ON A HORIZONTAL SURFACE (FRONT PANEL UPPERMOST) OR VERTICALLY
(
POWER SUPPLY CONNECTOR UPPERMOST) THIS ALLOWS THE WATER IN THE WATER FILTER TO VENT.
W
ATER COULD CONTAMINATE THE CONTROLLER MANIFOLD AND AFFECT CONTROLLER PERFORMANCE.
Note: In control mode, the water drain, located at one end of the unit near the carrying handle, produces
a flow of air and some water. The amount of water depends on the humidity and the operating
time in control mode.
C
AUTION:BEFORE USE, CHECK THE WATER DRAIN PIPE, IT MUST BE FREE OF OBSTRUCTION. WHEN IN CONTROL
MODE CHECK THAT A SMALL FLOW OF AIR COMES OUT OF THE DRAIN PIPE.
Notes:
1 When checking for a small flow of air do not block the drain pipe completely this causes a back-
pressure in the pipe and controller instability.
2 If no air flows from the drain pipe, when in control mode, switch off and start again. If no air
flows after a re-start, switch off and do not use the ADTS 505, return the unit to the repair depot.
C
AUTION: THE SIDE VENTS MUST NOT BE OBSTRUCTED, THIS UNIT REQUIRES AN AIRFLOW FOR THE INTERNAL COOLING FANS.
It is important that the position of the ADTS 505 in relation to the aircraft altitude sensors is
known. An altitude correction must be made to allow for the difference in height between the
reference level and the aircraft's altitude sensors (Figures 2-2 and 2-3). The Reference section
contains details of altitude correction.
WARNING: OBSERVE THE APPROPRIATE SAFETY INSTRUCTIONS AND TESTING PROCEDURES
DETAILED IN THE AIRCRAFT MAINTENANCE MANUALS AND COMPONENT
MAINTENANCE MANUALS.
