WARNING:
Be careful
not to over-depressurize
the housing. This will trigger the alarm and
require the sensor to be reset.
STEP 7:
Remove the pump by sliding the quick-disconnect collar (2) and put back the plug
(1) in the pressure valve.
If your housing fails to maintain a constant vacuum, proceed a thorough inspection of the
user serviceable O-rings of the housing. If unsuccessful in determining the source of the leak,
refrain from immersing the housing and return it to your authorized service center for
inspection.
NOTE:
Once your housing is under vacuum, it is important to pressurize it back to
ambient pressure before attempting to remove your port or open the housing. To
pressurize it back, insert the pump back into the valve (STEP 4) and remove
pressure release plug (#6). Once the hissing sound stops, you can remove the
pump (STEP 7). The housing is now back at ambient pressure.
