for Davey BT Series

Pressure Systems with

Please pass these instructions on to the operator of this equipment.

WARNING : The Torrium2 controller, pump and associated pipework operate

under pressure. Under no circumstances should the Torrium2 controller,

pump or associated pipework be disassembled unless the internal pressure

of the unit has been relieved. Failure to observe this warning will expose

persons to the possibility of personal injury and may also result in damage

to the pump, pipework or other property.

WARNING: Failure to follow these instructions and comply with all applicable

codes may cause serious bodily injury and/or property damage.

NOTE: Prior to installation remove the inlet and outlet

pipe transport plugs & associated seals from the

suction and/or discharge ports.

Prior to using this pump you must ensure that:

• The pump is installed in a safe and dry environment

• The pump enclosure has adequate drainage in the event of leakage

• Any transport plugs are removed

• The pipe-work is correctly sealed and supported

• The pump is primed correctly

• The power supply is correctly connected

• All steps have been taken for safe operation

Appropriate details for all of these items are contained in the following Installation

and Operating Instructions. Read these in their entirety before switching on this

pump. If you are uncertain as to any of these Installation and Operating Instructions

please contact your Davey dealer or the appropriate Davey ofce as listed on the

back of this document.

Congratulations on your purchase of a high quality, Davey pressure system. All

components have been designed and manufactured to give trouble free, reliable

operation.

Your new pressure system incorporates ‘Torrium2’, electronic ow controller – a

Davey designed unit that enables the use of a highly efcient pump design and

offers the following benets:–

1. Enables the pump to deliver a constant ow of water particularly at low ow

rates – reducing the inconvenience of pressure variation in showers etc.

2. Provides automatic “cut-out” protection should the pump run out of water or

overheat*, should the pump fail to start due to low voltage or a blockage in the pump.

Provides an easy to understand visual representation of the system status.

4. Has adaptive pressure cut-in which allows the pump to start at approximately

80% of the maximum pressure at last shut-down. This allows the controller to

accommodate varying inlet pressures and pump performance.

5. Automatic retry functions in the event of a critical system fault.

6. Easy visual guide to the status of the inbuilt surge arrestor.

7. Choice of both vertical and horizontal outlets.

* Motor overload / overheat protection included. Motor has its own overload /

overheat protection.

Before installing your new pump, please read all instructions carefully as failures

caused by incorrect installation or operation are not covered by the guarantee. Your

Davey pressure system is designed to handle clean water. The system should not be

used for any other purpose without specic referral to Davey. The use of the system to

pump ammable, corrosive and other materials of a hazardous nature is specically

excluded.

NOTE: Prior to installation remove the red transport plugs from the suction and/or discharge.

Fitting the Torrium2 directly to the Pump

The Torrium2 is tted with a rotary coupling. This

coupling allows the pump controller to be tted

simply and easily to the pump discharge.

The coupling has an oring seal. The controller

adaptor nut is able to rotate independent of the

Torrium2 and the complete pump, this allows it

to be tightened onto the pump easily. For ease

of installation a tightening tool is included with

Torrium2 to tighten the controller nut to ensure a

rm connection to your controller.

The ability to rotate the adaptor nut also means that the complete controller, once

tted to the pump, can be rotated a full 360oin the horizontal plane, without causing

the coupling to unscrew from the pump outlet.

DO NOT USE TEFLON TAPE OR THREAD

SEALING COMPOUNDS WHEN FITTING

TORRIUM2 DIRECTLY TO THE PUMP

With Torrium2 you can connect the discharge pipework to the

discharge port and/or the vertical priming port. The priming port is

able to be used as a discharge port.

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 5 gallon capacity) onto the priming port /

vertical discharge port.

For optimal draw off, see section on “Extra Draw-off Capacity.”

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 the enclosed exible

connection to allow for ease of access to the check valve.

Choosing a Site

Choose a site with a rm 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 Booster System

To protect your pressure booster 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

rm base allowing for drainage, to avoid damage to ooring

etc., that over time may occur from leaking pipe joints or

pump seals. Do not mount the pump vertically. Never place

ammable materials on or near your pump.

WARNING: Some insects, such as small ants, nd electrical devices

attractive for various reasons. If your pump enclosure is susceptible to

insect infestation you should implement a suitable pest control plan.

FREEZING CONDITIONS: In situations subject to freezing, drain water from

pump, tank & pipework to avoid damage not covered under guarantee.

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.

BT14-30, BT20-30 and BT14-45 models are 115 volt 60Hz models, tted with

NEMA 5-15P plugs intended for direct connection to a three pin wall socket.

BT20-40 and BT30-30 models are 230 volt 60Hz only and are tted with NEMA 6-15P

plugs intended for direct connection to a 6-15R three pin wall socket. The color codes

are: Green = Ground/Earth, Black = Hot, Active or L1, White = Neutral or L2.

Ensure that the circuit including the breakers on the power supply have sufcient

capacity to accommodate pump starting amperage. Davey recommend a minimum

circuit capacity of 20 amps for 115 volt models and 10 amps for 230 volt models.

All wiring must conform to National (NEC), CSA, state, provincial, and local

codes. Power supply voltage, phase and controls must match motor.

Auto-retry and Water Return Modes

Should your Torrium2 detect a loss of prime, after stopping the pump, it will wait

ve 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 ow 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 tted to this pump has a metal

oxide varistor (MOV) tted to help protect it’s circuit. This MOV is a “sacricial”

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.

Always disconnect and lockout all electrical power when installing

or working on pumps, motor or switches. Insure the power supply

breaker is off or the disconnect (where used) is off.

The Davey Torrium2 tted 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 qualied

electrician and comply with applicable local standards.

Ensure wall socket is correctly grounded.

Grounding of the motor is essential for your

protection and the protection of the motor.

Failure to ground motor can cause severe or

fatal electrical shock hazard.

Do not ground to a gas supply line.

Supply voltage must be within +10% of

nameplate voltage. Incorrect voltage can

cause re or seriously damage motor and

voids warranty. If in doubt consult a licensed

electrician.

If possible, connect pump to a separate

branch circuit with no other appliances on it.

Use unions at pipe connections to

enable easy removal and servicing.

Use sufcient tape to ensure airtight

seal and hand tighten only. To prevent

strain on pump threads always support

heavy inlet and outlet pipes. If there

is a likelihood the water supply may

contain solid particles such as pieces of

plant or vegetable matter, a lter should

be installed before the pump to avoid

blocking of water ways. Lay suction pipe

at a constant gradient to avoid air pockets

which may reduce pump efciency.

NOTE: Suction leaks are the largest cause of poor pump performance and

are difcult to detect. Ensure all connections are completely sealed using

thread tape only.

Flexible pipe should be considered to allow for movement between

building, pump and/or water supply. Braided hose, reinforced hose or

polythene pipe are suitable.

Do not use pipe thread sealing compounds on any part of this pump. ONLY

use Teon sealing tape.

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 ow when pumping

longer distances.

NOTE: For protection, the Davey pump motors are tted with an automatic

reset thermal overload, constant tripping of this overload indicates a

problem e.g. low voltage at pump, excessive temperature (above 115°F) in

pump enclosure.

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 ow appliances connected to the pump, such as evaporative air

conditioners, slow lling toilet cisterns, etc.

Any additional accumulators can be installed downstream of the controller (ie.

between the controller and the rst 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, see table below.

6 7

Evaporative coolers, RO lters and extra draw-off capacity

Where a Torrium2 equipped pump is required to supply water to an evaporative cooler,

reverse osmosis (R.O.) lter or similar low ow 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

ows 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 ow is required from your system, Torrium2 will initiate instant start.

Fit the pressure tank downstream of the controller.

DO NOT USE THREAD SEALING COMPOUNDS, HEMP OR PIPE DOPE!

Where to use Check Valves and Foot Valves

The Torrium2 controller tted to BT Boosters has an inbuilt non-return (check) valve tted.

In ooded suction installations there is no need to have a suction non-return valve.

In some suction lift installations there may be good reason to modify the inbuilt

check valve to ensure that the discharge pressure is also applied to the suction line

and footvalve. This could be where the suction line was very long or where there

was concern regarding a leaking footvalve. This may not always be applicable and

it is acceptable to retain the inbuilt check valve in the Torrium2 on suction lifts with

good suction plumbing.

Should the inbuilt check valve be required to be modied though, an additional

accumulator should be tted to the discharge pipework, to ensure the pump is not

cycled on shut down. The size of this accumulator will depend on the size, length

and type of pipe used on the suction.

To modify the check valve for suction lift conditions, follow these simple steps: ➞

Torrium2 Check Valve Removal

Installations with ooded suction require

a gate or isolating valve so water supply

can be turned off for pump removal and

servicing.

1. Remove priming

cap and turn over

cap. Lugs on cap

will engage check

valve to unscrew

4. Tighten check

valve using

inverted priming

cap and replace

priming cap

2. Roll off o-rings

3. Re-install check

valve

Abrasive Materials

The pumping of abrasive materials will cause damage to the pressure

system which will then not be covered by the guarantee.

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. In some

cases an expansion tank may be

required. Please consult local codes

for expansion tank requirements.

NOTE: Always ensure hot water systems are installed in compliance with

manufacturers recommendations and in accordance with all local regulations.

Models Maximum Inlet Pressure

BT14-300 60 psi

BT30-30 & BT20-30 50 psi

BT14-45 40 psi

BT20-40 20 psi

NOTE: The above pressure

limits also apply to well

pump boosting.

Connection to your Water Source

FLOODED SUCTION - FROM CISTERN OR

STORAGE TANK

Installations with ooded suction require a gate

valve so water supply can be turned off for pump

removal and servicing.

FLOODED SUCTION - FROM MUNICIPAL

WATER SUPPLY OR WELL PUMP

Connection of Municipal Water Supply to

either Suction or Discharge of Pumps &

Pressure Systems

Most Water Supply Authorities have strict

regulations regarding direct connection of pumps to municipal water supplies. In

some cases an isolating tank is required between mains supply and pump. Directly

applied municipal pressure can exceed pump operating pressure and damage

pump (see table overleaf).

BELOW GROUND WATER SOURCES

Whenever the installation position of

the pump is higher than 3ft above the

lowest water level, a foot valve must

be used on the end of the suction pipe

as illustrated in (A). Ensure that the

foot valve is at least 11/2feet below

minimum water level.

A pressure reducing valve is required on the suction side of the pump when

the incoming pressure is greater than shown on the table above. In some

areas, local codes restrict maximum allowable home pressures, and in those

cases the pressure reducing valve will need to be set to lower pressures.

Note: The maximum System Pressure should not exceed 100psi.

damage resulting from incorrect or unauthorised installations.

Abrasive Materials

The pumping of abrasive materials will cause damage to the pressure

system which will then not be covered by the guarantee.

(DRIVEN) POINT INSTALLATIONS

When a Multistage Pressure Boosting System is installed on a (driven or well)

point, a check valve must be tted immediately on top of the driven point itself, as

shown in (B). DO NOT INSTALL THE CHECK VALVE AT THE PUMP OR AT THE

TOP OF THE WELL. DO NOT RUN THE PUMP WITHOUT WATER. NOTE: Be

certain to select the driven point to suit the well conditions and regulate the

ow rate from the pump accordingly.

DRIVEN SIZE MESH APPROX. MAX. CAPACITY OF DRIVEN POINT

11/4” 60 200 - 350 gal/hr

11/2” 60 350 - 600 gal/hr

2” 60 600 - 1150 gal/hr

Driven point ow capacities vary considerably. Check with the supplier to

ensure the pump and spear point are correctly matched.

After half an hour of constant running, Torrium2 will turn off the pump briey. This

momentary pause is completely normal and is the controller conrming that there’s

still water demand.

Priming and Operation

The Torrium2 module tted to your BT Booster 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 ll

casing and suction line (on ooded

suction or mains boosting, 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 ow

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.
