Operating Instructions for

Davey Speedman Compact

Constant Water

Pressure Systems

NOTE: Prior to installation remove the inlet and outlet
pipe transport plugs & associated seals from the
suction and/or discharge ports.

WARNING : The Speedman Compact system and associated pipework operate
under pressure. Under no circumstances should the Speedman Compact
System 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.

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 constant
pressure water pressure system. All components have been designed and
manufactured to give trouble free, reliable operation.

Your new pressure system incorporates the Speedman Compact,

electronic ow controller – a 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 pressure of water particularly

across a wide range of ow rates – reducing the inconvenience of

pressure variation in showers etc.

2. Provides automatic “cut-out” protection should the pump run out of
water, should the pump fail to start due to low voltage or a blockage in
the pump.

3. Provides warning indications for system faults.

4. Has adjustable pressure setting to allow for various operating
conditions.

5. Automatic retry functions in the event of a variety of system faults.

6. Motor overload protection included.

Before installing your new pump system, 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 inlet and outlet pipe transport
plugs from the suction and/or discharge.

Preparing Your System

On removing your Speedman Compact system from the carton check
that the standard orientation of the pump inlet and controller is suitable. If
required, the inlet can be re-orientated 180 degrees.

To rotate the pump inlet to the alternate position, prior to installation, undo

the two motor mounting bolts (8), the four controller mounting screws

(9) and the two support bracket capscrews (10). The pump can then be

rotated relative to the controller by loosening the rotary coupling slightly
(7). Re-position the support bracket to the holes on the opposite end of the

mounting base and re-afx with the support bracket capscrews. Re-position

the pump and controller on the base, tightening all items (7, 8, 9 and 10)
carefully.

Only connect the discharge pipework to the discharge port. The
priming port is not a discharge port.

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 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 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.

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.

Power Connection

Connect lead to power supply (220-240V 1phase 50Hz) as designated
on controller label. Note that while the pump motor is rated three phase,

the single phase supply is inverted to suit in the controller. Do not use

long extension leads as they cause substantial voltage drop, poor pump

performance and may cause motor overload.

The Davey Speedman Compact tted to this pump has a status indicator
mounted on its front panel. This will be illuminated whenever the Speedman
Compact senses that there is electrical power available. It will only work
when unit is connected to the correct electrical supply.

The electrical connections and checks must be made by a

qualied electrician and comply with applicable local standards.

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 Speedman Compact
controller tted to this system 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 control unit 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.

In accordance with AS 3350.2.41 we are obliged to inform you that this

appliance is not intended for use by young children or inrm persons unless

they have been adequately supervised by a responsible person to ensure
that they can use the appliance safely.
Young children should be supervised to ensure that they do not play with
the appliance.

NOTE: For protection, the Davey Speedman Compact controller is
equipped with an automatic reset current sensing overload, constant
tripping of this overload indicates a problem e.g. low voltage at pump,
excessive temperature (above 50°C) in pump enclosure.

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.

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

pump. ONLY use Teon sealing tape.

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.

Extra Draw-off Capacity

The Speedman Compact 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.

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 15kPa below the system
pressure setting.
