Maintenance:


The only maintenance required for the PPVS is that the front internal PTFE cone body
is kept clean and free from any resin build up. It is not normal that resin sticks and
builds up inside the PTFE Body. However should this occur and impact upon the PPVS
performance then the unit may be disassembled by removing the three body Screws
(0313) and Locking Ring (4521).


If the Diaphragm (6642) is removed take care to remove internal Spring (6643) and
keep safe. Remove any resin or dirt which might have accumulated in the PTFE body
top and reassemble the unit. Do not over tighten Locking Ring.


Once the PPVS is completely re-assembled, test its
function. If no test device is available, then connect air
supply and the output to the TAS whereupon it is
possible to suck* on the PPVS (clean end) to test if it
functions correctly.




















*Note Mouth suction vacuum is not normally higher than 500mb absolute
