Catalyst Changing
The catalyst used in the machine will need changing after after between 6 & 12
months use. Due to the restrictions imposed by Customs & Excise departments,
the Ventech Ripening Fluid contains de-naturants which will eventually poison the
catalyst causing reduced gas generation. We also recommend that if you are have
problems ripening, that you check the gas levels with a gas sampler such as
the GASTEC, details of which are at the end of the manual.
This is supplied by us, & it is possible that a group of ripeners in one area share the
cost of one kit, since it is only used infrequently.
We recommend that the user checks the catalyst once a month after the rst six
months operation from new or after a catalyst change, and examine the catalyst by
unscrewing the exhaust nozzle, when cold, and viewing the catalyst, which consists
of small white tubes lling the reactor. These should be loose & not welded together
by carbon. If left too long, it is difcult to remove the old catalyst, and will require an
exchange reactor. Once the catalyst starts getting heavily carbonated, it should be
emptied by turning the machine upside down and shaking out the old catalyst. It may
be necessary to loosen the catalyst with a long thin screwdriver or skewer. Once all
the catalyst is removed, the reactor can be relled with a new catalyst pack, taking
care not to over-tighten the exhaust nozzle when replacing. When relling, some of
the catalyst consist of triangular ceramic chips that should be put in rst, followed by
the tubular active catalyst.
Due to the low cost of the catalyst, it is better to change it sooner, rather than later.
This will be done automatically, if your machine is covered by a service contract, or
sent in for any service or repairs.
Before returning a machine for repair a few simple checks should be carried out,
which could save you the transport costs & downtime involved in sending a machine
in to your service centre.
Condition - No lights lit
First check the electrical supply to your machine, and if you have test-meter check
that you have mains supply across the two outside pins on the connector that plugs
into the socket.
