Removing the Squeeze Tube
At this time, the peristaltic pump squeeze tube either
needs to be lubricated or replaced as per the
instructions below.
The BioDoser monitors the running time of the
dosing pump and will display a reminder to replace
the squeeze tube when this time exceeds 50 hours.
PUMP SQUEEZE TUBE LUBRICATION AND
REPLACEMENT
!
Switch off the BioDoser and ensure that the pool
pump is also off.
!
Remove and inspect the squeeze tube. If it is
round and not flattened, and shows no visible
signs of wear, then it can simply be lubricated as
per the instructions in this section.
If the squeeze tube appears a little flattened and
has wear marks, then it is best to replace it. A new
squeeze tube can be ordered at bionizer.com.au.
Damage caused by acid leaking from a broken
squeeze tube is not covered by the warranty, so it
is your responsibility to check and replace it as
necessary.

Lubricating the Squeeze Tube
Refitting the Squeeze Tube
(Skip this step when replacing squeeze tube, as these
are supplied pre-lubricated.)
Apply a
THIN SMEAR
of Silicon grease to the
squeeze tube and pump rotor shaft as shown above.
DO NOT
over-lubricate, as this will attract dirt and
grit, which will cause premature wear of the squeeze
tube and rollers.
WARNING : Use only silicon grease. Petroleum gel
and other oil-based lubricants may cause the
squeeze tube to break down, resulting in leakage.
Pull out the pump rotor a little, and place the
squeeze tube between the pump body and the two
rollers.
Push the squeeze tube and rotor into the pump body.
Ensure that the inlet and outlet are seated in the
guides on each side of the pump body.
Refitting the Pump Cover
Re-fit the pump cover until it clips into place. There
should be no gaps anywhere between the pump
body and cover. Ensure that the squeeze tube is not
pinched on either side, after the cover is replaced.
Apply Silicon
grease here.
