The Davey Speedman Compact fitted 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

qualified electrician and comply with applicable local standards.

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.

Choosing a Site

Choose a site with a firm 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 firm base

allowing for drainage, to avoid damage to flooring

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, find electrical
devices attractive for various reasons. If your pump enclosure is
susceptible to insect infestation you should implement a suitable
pest control plan.

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 fitted to this system has a metal oxide varistor (MOV) fitted to

help protect it’s circuit. This MOV is a “sacrificial” 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.
