PRESERVE’ switch should be off at this time, the vent cycle will run automatically, then
will stop after 30 seconds and the Green LED labeled ‘OK TO OPEN’ will illuminate.
Section-9.1: General maintenance - preventing system leaks
9.1.1 The Coffee Freshness System operates above atmospheric pressure, therefore
it is important to keep the system leak tight in order to prevent the preservation gas from
leaking out of the Airtight Canister during Coffee preservation.
9.1.2 Cleaning the lid o-ring and top surface of the Airtight Canister.
a. The lid of the Coffee Freshness System has a rubber o-ring that seals
against the top surface of the Airtight Canister. It is important to keep this
o-ring and the top surface of the Airtight Canister free of coffee particles or
any other debris in order to prevent leaks.
b. It is recommended to clean the lid o-ring and top surface of the Airtight
Canister at each opening. At a minimum, these surfaced must be cleaned
anytime coffee particles or debris are noticed on these surfaces by wiping
them clean with a damp microfiber towel [Provided] (Figs-10, 11). Leave a
portion of the towel dry or use a separate dry microfiber towel to dry these
surfaces before closing the lid.
9.1.3 Cleaning the Base assembly o-ring and Airtight Canister check valve surface.
c. The Base assembly of the Coffee Freshness System has a rubber o-ring
located on the baseplate which interfaces with a sealing surface on the
check valve that is installed in the bottom of the Airtight Canister. It is
important to keep the o-ring and the check valve surface free of coffee
particles and debris in order to prevent leaks.
d. It is recommended to clean the o-ring on the baseplate and the Airtight
Canister check valve sealing surface once weekly or as needed if you
notice coffee particles or debris in these areas.
e. To clean the o-ring on the baseplate and the Airtight Canister check valve
sealing surface, remove the Airtight Canister from the Base assembly by
following steps 7.2 - 7.4 for a pressurized Airtight Canister or step 7.5 for a
vented Airtight Canister.
f. Clean the o-ring on the baseplate (Fig-12) and the Airtight Canister check
valve sealing surface (Fig-13) by wiping these surfaces clean with a damp
microfiber towel [Provided]. Leave a portion of the towel dry or use a
separate dry microfiber towel to dry these surfaces then reinstall the
Airtight Canister on the Base assembly by following steps 3.2, 3.8 - 3.9.
