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

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.

3.

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 360o in 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.

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.

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.

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.
