7.13 SMS Feedback:
In addition to the above commands all registered
phone numbers will receive advice in the event of the
pump responding to any input or command to action
(i.e. start or stop). This means all users are aware if
a pump is responding to an input or a command.
E.g. should a remote switch start or fire sensor start
event occur, then a SMS will be sent to all registered
phone numbers.
WARNING: Pump can only be stopped
with SMS command or manual
shutdown when start initiated by
Fire Sensors or Emergency Button(s).
7.14 Removal of Impeller:
WARNING: Before working on the
engine or pump ensure the battery is
disconnected from the engine and the
key switch is in the “OFF” position.
This pump has both automatic and
remote start capabilities which will
allow the engine to “crank” or turn
over, though not actually start, even if
the key switch has been turned to the
“OFF” position. Disconnect the red
coloured lead from the positive
(+ve) terminal first.
Single impeller models:
Pump impeller is screwed clockwise onto the engine
shaft. The impeller assembly is fixed together by
a setscrew. It can be disassembled in two halves
by removing the setscrew. This practice allows
the impeller to be cleaned without disrupting the
mechanical seal and potentially creating additional
service replacements.
Alternatively, the entire impeller assembly can be
removed. To remove the entire impeller assembly,
unscrew locking setscrew, or impeller/s anti-clockwise
using a socket in eye of impeller. If difficult to remove,
lock engine crankshaft at recoil starter end.
Twin impeller models:
Second stage pump impeller is screwed clockwise
onto the engine shaft. The complete impellers’
assembly is fixed together by a single setscrew. The
impellers can be disassembled in two halves by:
• unscrew locking setscrew;
• remove first impeller front and rear
• remove diffusers; and
• remove second impeller’s front half.
This practice allows the impellers to be cleaned
without disrupting the mechanical seal and
potentially creating additional service replacements.
Alternatively, the entire impeller assemblies can be
removed. To remove the entire impeller assembly:
• unscrew locking setscrew;
• remove first impeller front and rear
• remove diffusers; and
• remove second impeller anti-clockwise using a
socket in eye of impeller. If difficult to remove,
lock engine crankshaft at recoil starter end.
