DEEP EPIC Setup

Seal Check
Seal Check Manual.
Follow the procedures in the Seal Check manual for verifying
integrity of the housing and monitor.
CAUTION.
DO NOT draw more than 6 in Hg vacuum on DEEP EPIC. More vacuum
can inhibit the transfer of heat away from the housing.
NOTE.
Pulling a vacuum on DEEP EPIC will take several minutes or more. Further,
the vacuum indication will take several minutes to ‘settle’ due to the size of DEEP
EPIC.
Seal Check both Housing and RED PRO Monitor.
The RED PRO monitor also
has a Seal Check fitting. After drawing a vacuum on the housing, note the vacuum
level on the gage.
Next, move the Seal Check hose to the RED PRO monitor. Draw a vacuum close
(within 1 in Hg) to that of the main housing. Remove and plug the Seal Check fitting
on the RED PRO monitor.
Move the Seal Check hose back to the main DEEP EPIC housing and start the
monitoring process.
Why do this?
The LCD cable, while waterblocked, is not air-blocked. After
drawing vacuum on the monitor, air passes from there to the main shell until the
vacuum is equalized between them. By drawing a vacuum on the monitor, very little
air must pass between the shells, so the ‘settling’ process and determination of
housing integrity takes far less time.
The Seal Check fitting is located
on the lower left of the shell.
The Seal Check fitting for the
External Monitor is located next
to the cable.
