Auto-retry and Water Return Modes
Should your Torrium2 ® detect a loss of prime, after stopping the pump, it will wait
five minutes before activating Auto-retry and Water Return modes. Auto-retry
automatically starts the pump to see if the pump is now primed. It does this after 5
mins, 30 mins, 1 hr, 2 hrs, 8 hrs, 16 hrs and 32 hrs. Water return mode will restart
the pump automatically if the Torrium2 ® detects water flow through it.
Electrical Power Surge Protection
An electrical power surge or spike can travel on the supply lines and cause serious
damage to your electrical equipment. The Torrium2 ® fitted to this pump has a metal
oxide varistor (MOV) fitted to help protect it’s circuit. This MOV is a “sacrificial”
device, meaning that it effectively is gradually damaged every time it takes a surge.
The MOV is not a lightning arrestor and may not protect the Torrium2 ® if lightning or
a very powerful surge hits the pump unit.
If the installation is subject to electrical power surges or lightning we strongly
recommend the use of suitable additional surge protection devices on ALL electrical
equipment.
Surge Protector Status Window
To allow you to check the status of the inbuilt MOV in the Torrium2 ® there is a
viewing window at the back of the Torrium2 ® above the power lead entry / exit
grommet. The MOV is the blue disc shaped component. Should it be consumed
due to power spikes it will almost always blacken the viewing port. This will indicate
a non-warrantable failure.
In accordance with AS/NZS 60335.2.41 we are obliged to inform you that this pump is
not to be used by children or infirm persons and must not be used as a toy by children.
Pipe Connections
For best performance use P.V.C. or
polythene pipes at least the same
diameter as the pump’s inlet and delivery
outlet openings. Larger diameter pipe
may be used to minimise resistance to
flow when pumping longer distances.
NOTE: For protection, the Davey pump motors are fitted with an automatic
reset thermal overload, constant tripping of this overload indicates a
problem e.g. low voltage at pump, excessive temperature (above 50°C) in
pump enclosure.
Power Connection
Connect lead to power supply designated on pump label. Do not use long
extension leads as they cause substantial voltage drop, poor pump performance
and may cause motor overload.
The Davey Torrium2 ® fitted to this pump has status indicator light mounted
on its front panel. These lights will only work when unit is connected to an
electrical supply.
The electrical connections and checks must be made by a qualified
electrician and comply with applicable local standards.
For Automatic Pressure Pumps Installed with a
Mains Pressure Hot Water System
To protect your system from damage caused by back
pressure from hot water systems. You should always
have installed on the hot water inlet an approved non-
return valve.
Connection of Mains Scheme or Town Water
Supply to either Suction or Discharge of Pumps &
Pressure Systems
Most Water Supply Authorities have strict regulations regarding direct connection of
pumps to mains water supplies. In most cases an isolating tank is required between
mains supply and pump. Davey also recommend this method. Directly applied
mains pressure can exceed pump operating pressure and damage pump.
Davey Water Products Pty Ltd can not
accept responsibility for loss or damage
resulting from incorrect or unauthorised
installations.
NOTE: Always ensure hot water
systems are installed in compliance with
manufacturers recommendations and in
accordance with all local regulations.
Priming and Operation
The Torrium2 ® module fitted to your HP or HS system is provided with a push
button “Prime” button. This button is used during initial priming of the pump and
also acts as a reset button if the Torrium2 ® switches out in pump protection mode.
1. Remove priming plug and fill
casing and suction line (on flooded
suction, simply open gate valve to
pump). When full, replace priming
plug.
2. Ensure outlet nearest
to pump is open.
3. Ensure all valves in suction line
are open.
4. Switch on power - The
status indicator light
will be illuminated
green and the pump
will run. A full flow
of water should be
discharged from the
open tap.
5. If the pump stops with the tap open
see troubleshooting checklist.
6. Close the open outlet or tap and
the pump should stop after a few
seconds (the status indicator light
should be illuminated red (constant).
If not, consult the troubleshooting
checklist.
To Reset if Pump switches out in
Pump Protection Mode
1. Make sure pump is primed.
2. Open tap, push prime button.
3. Close tap and pump will stop.
