Flotronic One-Nut - Maintenance

Maintenance
NO
TE:
Always disconnect the power supply from the control box before any maintenance
or cleaning operation is carried out.
Clean Sensors
In the event of a diaphragm failure the sensor housing will need to be cleaned to
remove all traces of product that may stop the system from resetting and thus the
pump from re-starting.
1. Unplug the sensors from the main control bo
x.
2
. Remove air domes from pump. (See pump IOM for de
tails)
3
. Clean the sensor port on the inside of the air dome to remove all traces of
product.
4. Dry the sensor port. Any cleaning solution left in the chamber m
ay be
de
tected as a failure upon system re-start.
5. Rebuild pump replacing failed compo
nents.
If
the contamination is difficult to remove from the port it is possible to unscrew the
PTFE sensor housing from the air dome to gain better access. If this is required
ensure that upon re-assembly the metal sealing ring is positioned over the external
thread of the PTFE housing to provide a seal between the air dome and the PTFE
sensor housing.
NOTE:
Ensure that the cleaning solution used is compatible with the items being cleaned.
Care should be taken not to apply harsh cleaning chemicals to the exposed sensor
section on the outside of the pump.
