Warnings & Safety

Installation

For electrical installation recycling requirements, consult your local electricity authority and conform to all

local and national regulations.

Disconnect and lock out electrical power before installing, servicing, or maintaining the unit.

Make sure that the unit is mechanically secure, and that it cannot roll or fall over and injure people or

damage property.

Rinse the unit thoroughly with clean water before working on it.

Rinse the components in water after dismantling.

Check the explosion risk before you weld or use electrical hand tools.

Allow all system and pump components to cool before you handle them.

Make sure that the product and its components have been thoroughly cleaned.

Do not open any vent or drain valves or remove any plugs while the system is pressurised. Make sure that

the pump is isolated from the system and that pressure is relieved before you disassemble the pump,

remove plugs, or disconnect piping.

Worn impeller and/or pump housing can have very sharp edges. Wear protective gloves.

Always perform a trial operation when starting the pump after a reassembly. If the pump was assembled

improperly, it may lead to abnormal operation, electrical error or water damage.

Use the pump dimensional drawing in order to ensure proper installation.

Provide a suitable barrier around the work area, for example, a guard rail.

The supply voltage variation

• Continuous running: max ±5% of the rated voltage.

• Intermittent running: max ±10% of the rated voltage.

To use the pump, the water temperature should be between 0°C and 40°C.

The pump should be used only for pumping water or water-based fluids. The pump should not be used to

pump fluids such as oil or organic solvents.

The pump must never be used to pump explosive liquids and should not be operated in an area where

explosive elements may be present.

The pump must not be used in a partially disassembled state.

Do not use the pump in an area where the water pressure exceeds the values given below, as it may

damage the pump, or cause a short or electrical shock.

If an excessive amount of sediment is drawn into the pump, it may cause the pump to wear, which can

lead to current leakage or electrical error.

Warnings & Safety

Make sure that all unused conductors are insulated.

You must ground all electrical equipment. This applies to the pump, all starting and running control

panel/s, and any monitoring equipment. Test the ground lead to verify that it is connected correctly.

If the motor cable is jerked loose by mistake, the ground conductor should be the last conductor to come

loose from its terminal. Make sure that the ground conductor is longer than the phase conductors. This

applies to both ends of the motor cable.

Risk of electrical shock or burn. You must connect an additional ground fault protection device to the

grounded connectors if persons may come into physical contact with the pump or pumped liquids.

If the pump is equipped with automatic level control and/or internal contactor, there is a risk of sudden

restart.

Do not insert your finger or any object into the pump’s inlet. Doing so may cause injury, and physical

damage.

Do not operate the pump below Continuous running Water Level (C.W.L) as doing so will damage the

pump, causing current leakage and electrical shock.

Personal injury hazard. Troubleshooting a live control panel exposes personnel to hazardous voltages.

Electrical troubleshooting must be done by a qualified electrician. Failure to follow these instructions will

result in serious personal injury, death, and/or property damage.

Always disconnect and lock out power before servicing to prevent unexpected start-up. Failure to do so

could result in death or serious injury.

Recycling Guidelines

Please recycle every worn and/or disused part and/or pump where possible. Local and national guidelines

must be followed. If local recycling facilities are not readily available, please contact your distributor to

obtain guidance.

Prior to Use

1. Inspect the product

a. Ensure that all items on the delivery note or packing list are present, and that no items are

damaged.

b. Unpack the goods and visually ensure that all parts are undamaged. Check that bolts and screws

have not come loose during transit.

c. If any issues are identified do not proceed further and immediately contact your Intrax dealer

from whom you purchased the product, or the nearest representative office. The delivery should

not be accepted or signed for prior to completion of all of the above checks.

2. Check the specification

a. Find the nameplate on the pump and verify that it is the one you have ordered.

b. Ensure that the voltage and frequency specifications match the original specification.

c. If any issues are identified do not proceed further and immediately contact your Intrax dealer

from whom you purchased the product, or the nearest representative office. The delivery should

not be accepted or signed for prior to completion of all of the above checks.

3. Method of starting

a. Ensure that the selected starting method is capable of driving your pump. Please note that

electrical motors are largely inductive, so the current may significantly spike on start-up. As a

general rule:

i. DOL (Direct On Line) start can create a current spike up to approximately 6 times the

rated current.

ii. Soft Start can create a current spike up to approximately 3 times the rated current.

iii. Inverter drive can create a current spike up to approximately 1.2 times the rated current.

b. If a starting method is yet to be chosen, always choose an inverter drive where budget allows,

followed by soft start, and only use DOL where necessary. It is highly recommended to avoid DOL

on all pumps over 18.5kW.

Installation Considerations

1. Considerations

a. Mounting

i. Audex pumps should be either suspended from provided lifting points or rings, or

suspended by purpose designed clamps around the pump.

ii. Audex pumps should never be stood on the base of a tank where silt or sand could build

up.

iii. Ensure that the cable has no sharp bends, is not pinched, and cannot be drawn into the

pump inlet.

iv. Ensure that the hose or pipework is firmly attached to the pump outlet

v. The pump should never be suspended by the cable or pipework.

b. Suction requirements

i. All Audex pumps require submersion up to the rated continuous working level as a

minimum. This information is in the data tables later in this manual.

ii. All Audex pumps have a maximum submersion pressure, this information is in the data

tables later in this manual.

iii. The pump strainer / inlet should never be blocked.

iv. The fluid should not contain particles with any dimensions larger than the rated pump

solids passage.

c. Ensure that the pump noise level is below the site / location permittable level.

Installation Preparation

1. Pre-installation

a. Recommended required install tools

i. AC voltmeter

ii. AC ammeter (non-contact CT type)

iii. Insulation resistance tester

iv. Spanners / wrenches

v. Screwdrivers

vi. Cable preparation tools as appropriate

vii. Electrical panel key

Installation Electrical

1. Electrical connection

a. Preparation

i. Ensure that the voltage and frequency of the supply match the requirements on the data

plate.

ii. Ensure that all circuit breakers and similar equipment are rated correctly, and set to the

appropriate level where applicable.

iii. Ensure that all cables and wires are of a sufficient specification for the required current

and voltage, and comply with all relevant regulations.

iv. Ensure that the pump cable sheath is completely undamaged. Any cuts or holes which

penetrate the outer sheath or further are not permitted, and the pump should not be used if

any such fault is present. Water can travel down the inside of the outer sheath and into the

motor.

v. If the pump will be running intermittently, ensure that the max start/stops of the pump are

complied with through the appropriate means.

vi. The cable gland on the pump is resin-filled to ensure weathertightness. If the cable is

strained in any direction this may be compromised and therefore the pump should be

returned to the dealer / manufacturer for the cable to be re-set in resin.

b. Connection

i. Ensure that control panel entry holes are suitably protected to prevent cable damage and

isolate accidental cable strain to outside the panel. In most cases this will be an IP rated cable

gland.

ii. Use cable crimps or ferrules where possible to ensure that all strands of each core are

used, remain undamaged, and are protected.

iii. Earth should always be connected to the earth terminal in the panel.

iv. With three phase pumps the three live connections are usually numbered 1 to 3, and most

commonly connected as follows for the correct phase rotation:

1. Normally Brown / Red

2. Normally Black

3. Normally Grey / Gray / Blue
