If it not convenient to carry out this inspection immediately it is possible to postpone
it for a short time.
3.4.1
To Postpone the Sevice:
Press the reset button once:
The appropriate cylinder LED will change to constant “amber”
and the external alarm will be reset, allowing the unit to continue to run without an external
alarm for 168 hours run time.
When the alarm is repeated, it should be serviced immediately – and not postponed
further.
3.4.2
To Service the unit:
Press the reset button:
This will cause the appropriate LED to change to constant “amber”, the external alarm to be
reset.
Press the service button again:
(this should be within ten seconds of the first push).
This will cause a “service routine” to be implemented. Once this is complete,
Isolate the electrical supply:
Inspect the cylinder:
As described in the maintenance section of the operating and
maintenance manual.
Clean the cylinder:
As described in the maintenance section of the operating and
maintenance manual.
Power up the unit:
Press the reset button:
This will cause the appropriate cylinder LED will change to constant “amber” and the external
alarm will be reset, allowing the unit to continue to run without an external alarm for a further
168 run hours..
Press the reset button again:
(this should be within ten seconds of the first push).
This will reset all the relevant timers including the hours run timer.
NB if the button is not pressed a second time then the alarm will only be postponed,
and will quickly return.

Event in Progress:
This is a transitional state while the unit is actually performing a
particular routine. The LED indication is for information only and requires no user
intervention.
6
Event Completed:
If one of the above conditions have been implemented, when it has been
completed, the unit by default will continue to run, however it is possible to change this to
“stop” (via a display either fitted or hand held) if this is the case this condition will be
exhibited, and the unit will not run until the condition has been reset, by either:
i) Units fitted with an Alpha-numeric display:
Power the unit right off, using the local
isolator (not the unit on/off switch), waiting ten seconds, then re-applying power. When
the message “event complete” is once again displayed press the o.k. button, and the unit
will revert back to it’s operational state.
ii) Units not fitted with a display:
Power the unit right off, using the local isolator (not the
unit on/off switch), waiting ten seconds, then re-applying power. When the constant green
“event complete” indication is showing, press the unit “fault reset” button, which is located
on the fascia above the “Vapac” Logo.
7
Constant output:
i)
Units fitted with an Alpha-numeric display:
This is another transitional state, and
once the “constant output period” has expired, the unit will revert to normal “controlled”
operation. The LED indication will automatically revert to the cylinder’s “current state”.
ii)
Units not fitted with a display:
Once the testing of the unit is complete, the jumper J1
on the configuration PCB should be removed from the full output position and returned to
its normal operating position.
