Puritan Bennett™ 700 Series Ventilator System Service Manual
NOTE:
• When installing the male DISS fitting to the regulator body, first remove any PTFE
tape (if reusing existing fitting) and apply new tape (P/N G-060759-00) to the
threads. To prevent tape debris from coming loose and entering the pneumatic
system, do not wrap tape around the first two threads.
• After installing or assembling male DISS fitting or any oxygen adapters, test for
leaks. To leak test, apply leak test fluid (P/N 4-004489-00) with a suitable small brush
to all connections between where the hose attaches to the adapters and where the
male DISS fitting attaches to the regulator body. If new bubbles form, repair the
leak. Use a clean cloth to remove the leak detector.
