Trouble Shooting Check List
a) PUMP HAS STOPPED OR MOTOR RUNS FOR SHORT PERIOD ONLY
WHEN SWITCHED ON OR PRIME BUTTON PUSHED, BUT DOES
NOT PUMP - YELLOW STATUS INDICATOR LIGHT ILLUMINATED.
1. Suction line and pump body not filled with water.
2. Air leaks in suction lines or suction pipe not under water.
3. Air trapped in suction lines (also possible with flooded suction due to uneven
rise in piping; eliminate humps and hollows).
4. No water at source or water level too low.
5. Valve on suction lines closed. Open valve & pump will restart automatically
or press “Prime” button.
b) PUMP SWITCHES ON AND OFF FREQUENTLY (CYCLING)
1. Cycling may occasionally be caused by float valves filling tanks.
2. Leaking taps, float valves etc. check plumbing.
3. Leaking check valve/foot valve.
c) MOTOR DOESN’T START WHEN SWITCHED ON - INDICATOR LIGHTS NOT
ILLUMINATED
1. Power not connected or no power available from supply outlet.
d) MOTOR STOPS - YELLOW STATUS INDICATOR LIGHT IS ILLUMINATED.
1. Motor ”over temperature” cut-out tripped. Consult Davey dealer.
2. Motor not free to turn - e.g. a jammed impeller. Consult Davey dealer.
3. Prime button has been held in for too long. Release prime button and
switch off power for 1 minute to allow unit to reset.
4. Your Torrium2 ® has detected high water temperature in the pump. Once the
water has cooled the Torrium2 ® will automatically restart the pump.
e) PUMP WILL NOT STOP
1. Water leaks on discharge side of pump.
f) PUMP WILL OPERATE NORMALLY INITIALLY BUT WILL NOT RESTART
ON WATER DEMAND - STATUS INDICATOR LIGHT NOT ILLUMINATED
1. Power supply problem - see c) 1.
g) PUMP WILL OPERATE NORMALLY INITIALLY BUT WILL NOT RESTART ON
WATER DEMAND - YELLOW STATUS INDICATOR LIGHT IS ILLUMINATED.
1. Suction air leak - pump has partially lost prime.
2. Blocked impellers or suction.
3. Discharge valve closed - open valve.
WARNING: Automatic reset thermal overloads may allow the pump to restart
without warning. Always disconnect the pump motor from the electrical
supply before maintenance or repairs.
WARNING: When servicing or attending pump and/or controllers, always
ensure power is switched off and lead unplugged. Electrical connections
should be serviced only by qualified persons. Choosing a Site
Choose a site with a firm base and as close to the water source as possible with
correct power supply. Make sure your pressure system is always connected to an
adequate, reliable source of clean water.
Housing your Davey Pressure System
To protect your pressure system from the weather, make sure the
pump house is both water proof, frost free and has adequate
ventilation. The pump should be horizontally mounted on a
firm base allowing for drainage, to avoid damage to flooring
etc., that over time may occur from leaking pipe joints or
pump seals. Do not mount the pump vertically.
Discharge Connections
The Torrrium2 ® offers the option of using one or both outlet options.
Use of the horizontal outlet only allows for either:
1. Easy access to prime the pump and / or the removal of the inbuilt Torrium check
valve
2. Fitment of a pressure tank (up to 20 litre capacity) onto the priming port / vertical
discharge port
If you use the vertical outlet instead or as well, you need to consider access to the
inbuilt check valve in the Torrium. Davey suggest you use a flexible connection and /
or union connection to allow for ease of access to the check valve.
Pressure Indicator Window
Torrium has an easy to read pressure indicator window on the side of the inbuilt
pressure vessel – see Figure 1 on page 3.
If the pressure is low the window will show mainly red. If the pressure is at
maximum (i.e. 450kPa for TT45 and 700kPa for TT70 models) the window will show
mainly green.
The window can also help analyse the occurrence of unwanted leaks. If the colour
band in the window is moving towards red, this shows that pressure is decreasing.
If the colour band in the window is moving towards green, this shows that pressure
is increasing.
WARNING: Some insects, such as small ants, find electrical devices
attractive for various reasons. If your pump enclosure is susceptible to
insect infestation you should implement a suitable pest control plan.
Maintenance
The only regular attention your new pressure system may require will be if you
have used an additional pressure tank. Depending on the tank used you may need
to check the pressure tank’s air charge every 6 months. Follow the instructions
applicable to each tank.
WARNING : Under no circumstances should Torrium2 ® controller be
disassembled. Failure to observe this warning will expose persons to the
possibility of personal injury and may also result in damage to other property.
Do not dismantle, no user serviceable parts, spring under pressure.
