STEP 3:
Remove the valve plug (#1) by sliding the quick-disconnect collar (#2).
STEP 4:
Insert the pump stem (#5) in the pressure valve and release the quick
disconnect collar (#2).
STEP 5:
Make sure the pressure release plug (#6) is screwed all the way in
(clockwise).
STEP 6:
Build vacuum inside your housing by pumping the handle (#7). The
amount of pumping required will vary according to the housing
dimensions and the port configuration being used. However, the
proper amount of vacuum should always be attainable within a
reasonable delay. Refer to vacuum monitoring LED code table.
STEP 7:
Remove the pump by sliding the quick-disconnect collar (#2) and put
back the plug (#1) in the pressure valve.
Note:
Be careful
not to over-depressurize
the housing. This will trigger the
alarm and require opening the housing and starting the procedure
all over again.
