Cleaning the Aerosol Inlet
Under normal operating conditions, the external aerosol inlet will
remain clean and unobstructed. Under very dirty conditions; however,
the inlet may become obstructed with vegetative debris or insects. To
ensure the inside of the aerosol inlet is clean, periodically remove
Omni-directional inlet and blow compressed air through the bottom of
the inlet.
C a u t i o n
Do not disassemble the Environmental Enclosure
aerosol inlet for any reason. It is not designed for
field service and reassembly.
Emptying the Water Trap
If any water or moisture has accumulated in the water trap,
unscrew the water trap from the Omni-directional inlet and empty
it.
The bottle must be securely hand tightened to seal against the
O-ring to prevent leaking. Make sure the tightly secured bottle is
oriented in the position shown in Figure 38
.
If water trap top is removed from fitting, re-apply Teflon
®
pipe tape
to fitting before installing cap to ensure a good seal is maintained.
