pressing the Alarm Mute button for a minimum of 3
seconds (Refer to "Alarm Mute" on page 10).
The triangular Alarm symbol is displayed with one or
more of the following indicators:
• Low Pressure (refer to "Low Pressure" on page 11).
• High Pressure (refer to "High Pressure" on page 11).
• Pump Fault (refer to "Pump Fault" on page 12).
• Power (refer to "Power Fail" on page 12).

For all alarm conditions except Power Fail, once
the alarm condition has been detected and
displayed, it can only be cancelled by pressing and
holding the Run/Standby button to put the pump into
Standby.
Refer to Section 9, Page 24 "Troubleshooting and
Alarm Conditions" for possible causes of the above
alarm conditions.
The Pump Fault indicator is illuminated when an
internal pump malfunction is detected.
The fault can only be rectified by carrying out a service
on the pump.
The Power indicator will illuminate when a mains power
failure has been detected.
The alarm will continue until:
• The mains power is resumed, or
• You press and hold the Run/Standby button to put
the pump into Standby.
The Power Fail Alarm is powered by a rechargeable
battery. The duration of the alarm will depend on the
level of charge in the battery. The battery may have
become discharged or reached the end of its life; it is
therefore recommended that the alarm is tested before
the pump is used (refer to "Testing the Power Fail
Alarm" on page 8).

If the Power Fail Alarm does not operate after this
test and a service engineer has been called, the
pump can continue to be used with regular checks of
the Power-On status. All other alarms will continue
to function as normal.
The Service Indicator symbol will be illuminated after a
set number of running hours to indicate that the pump is
ready for a service. This service period is set to 12
months run time.

The pump will continue to operate normally even
when the Service Indicator symbol is illuminated.
