In systems built with FMI Heavy Duty Piston-Type Circulation Pump, confirm
that the clearance at the bottom of the piston is greater than > 2mm. To
confirm this, first mark the piston at the bottom of its stroke while it is in the
pump drive. Then mark the piston when it is disconnected from the drive, with
the piston pressed fully into its housing. The difference should be greater than
or equal to >= 2mm. If it is less than < 2mm, clean the bottom of the housing
with acid. Replace the lip seals (see item L in service kit) and the gland washer
(see item M in the service kit) in the Circulation Pump. Grease piston drive
bearing (see item U in service kit). Verify that it is running smoothly. If there
are no HCl Water In and HCl Water Out ports on the BioTector, this item does
not apply.
In systems built with FMI Heavy Duty Piston-Type Circulation Pump, confirm
that the knurled nuts are tight. If there are no HCl Water In and HCl Water Out
ports on the BioTector, this item does not apply.
In systems built with flapper-valve (diaphragm) type Circulation Pump
(KNF100 or KNF300), follow the maintenance procedures in information
sheets “M007 Maintenance on the NF100 Pump” or “M008 Maintenance on
the NF300 Pump”. As the 6 and 12 month service components required for
these pumps are not part of the standard BioTector service kit, they should be
ordered separately.
Check the O

/O
3
inlet port in the reactor for build-up of salts. Clean the inlet
tube if necessary.
Confirm that the temperature of the ozone destructor has dropped to ambient
temperature level. Open the ozone destructor. The ozone destructor should
never be opened when it is hot as the threads may seize. Confirm that the
PTFE filters (discs) in the ozone destructor are clean. If there is any material
build up (e.g. white powder), wash the filters using DI Water or tap water and
dry. Do not use compressed air or any gas to clean the filters.
Replace the PTFE wool in the ozone destructor (see items AF and AG in
service kit. These items are included with item X in the 12
th
month service kit).
Replace the catalyst and the PTFE wool in the ozone destructor (see item X in
service kit, which includes items AF and AG). Note that in applications
containing HCl or HF, the ozone destructor catalyst may require more frequent
replacement.
Replace the o-ring in the Ozone Destructor (see item P in service kit).
Reconnect power to ozone destructor heater.
Remove the tapes, which are used to seal the ends of the supplied CO
2
filter
(see item W in service kit). Replace the CO
2
filter on the Base reagent
container. Seal the Base container tightly.
Check the pressure on the oxygen regulator. The pressure should be 350
mbar when the MFC flow is set to 20 l/h (liters per hour) in Oxidation Phase
Simulate menu.
Check the operation of the Mass Flow Controller.
