Extra Draw-off Capacity
The Torrium2 controller has an in-built accumulator which will
accommodate small leaks. In some applications it may be appropriate to
install additional accumulator (Supercell pressure tank) capacity. These
applications includes:
• Long suction lines (see Suction Lines / Lift)
• Low flow appliances connected to the pump, such as evaporative air
conditioners, slow filling toilet cisterns, etc.
Any additional accumulators can be installed either in place of the priming
plug (see Figure 1) for tanks up to 20 litres total capacity, or for larger
tanks, downstream of the controller (ie. between the controller and the first
outlet).
Where extra draw-off capacity is utilised the additional pressure tank
should have a pre-charge of 70% of the maximum system (shut-off)
pressure.
Evaporative coolers, RO filters and extra draw-off
capacity
Where a Torrium2 equipped pump is required to supply water to an
evaporative cooler, reverse osmosis (R.O.) filter or similar low flow device,
the Torrium2 will detect the limited demand. This will result in the Torrium2
adapting to the slow demand. The pump start pressure will be allowed
to drop to a lower cut in pressure each time low flows are detected. To
provide the maximum draw-off from the additional pressure tank, the tank’s
pre-charge should be set at 45% of the pump shut-off pressure.
If normal flow is required from your system, Torrium2 will initiate instant start.
Fit the Supercell pressure tank (up to 20 litres total capacity) to the tank
connection/priming port
with thread tape and pipe socket
. Firmly
hand
tighten. For larger tanks, these should be installed downstream of the
controller.
NOTE: If fitting a tank to the priming port, you may require a 1”
BSP socket, since both Torrium2 prime port and tank are 1” male
threads.
DO NOT USE THREAD SEALING COMPOUNDS, HEMP OR PIPE DOPE!
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.
