Prior to using this system you must ensure that:

• The system is installed in a safe and dry environment

• The system 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

CHOOSING A SITE

Choose a site with a rm mounting position. Allow room for removal of the

lamp and sleeve during servicing. Leave a chamber lengths space above
the lamp cover & connector end for lamp removal.

To protect your system from the weather, make sure the site is ood proof,

water proof, frost free and has adequate ventilation. Allow for drainage, to

avoid damage due to ooding etc., that over time may occur from leaking
pipe joints or seals.

POWER CONNECTION

Connect lead to power supply designated on control box label. Check that

the earth is connected to the stainless steel chambers using bolt provided
on the chamber.

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

attractive for various reasons. If your site or enclosure is susceptible to
insect infestation you should implement a suitable pest control plan.

WARNING: When servicing or attending your Aquashield MAX, always ensure
power is switched off and lead unplugged. Electrical connections should be

serviced only by qualied persons. If the electrical supply lead of this system
is damaged, it must only be replaced by a qualied service personnel.

The Sterio® control box has a red LED alarm indicator light mounted on

its front panel, adjacent to the amber “power on” LED. This light will be

illuminated whenever the Sterio® control box senses no lamp current. There

is also an audible alarm in the event of lamp failure. The LED and/or alarm
will only work when unit is connected to the correct electrical supply.

NOTE:
a) For protection, the Davey® pump motor is tted with an automatic

“over temperature” cut-out. Constant tripping of this overload device
indicates a problem e.g. low voltage at pump, excessive ambient
temperature (above 50°C) in pump enclosure.

b) The Torrium® control device may have to be reset after rectifying any of

the above operating troubles. This is done by pushing in the “prime”
button and releasing it after 2 seconds, or switching the power supply
off then on.

This appliance is not intended for use by persons (including children) with
reduced physical, sensory or mental capabilities, or lack of experience
and knowledge, unless they have been given supervision or instruction
concerning use of the appliance by a person responsible for their safety.

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.

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.

Use unions at pipe connections to enable easy removal and servicing.

Use sufcient tape to ensure airtight seal and do not over tighten. To

prevent strain on unit threads always support heavy inlet and outlet pipes.

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.

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

use Teon sealing tape.

NOTE: Prior to installation remove the transport plugs from the inlet, outlet
and lamp end cap.

Do not use pipe thread sealing compounds (especially hemp) on any part

of this unit. ONLY use Teon sealing tape.

RainBank® controllers can only be connected to mains water, by a qualied
licensed plumber.

PUMP CONTROLLERS

TORRIUM

®

Your new system incorporates ‘Torrium®’, 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.

3. Provides warning indications for critical and noncritical system faults.

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.

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

Status Indicator

The Torrium® has a status indicator light on the front panel. This light will
enable you to understand what your pump is doing.

The electrical connections and checks must be made by a qualied

electrician and comply with applicable local standards.

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

Both the Red & Green Indicators are shown in the same window. It is

possible for the pump to be running (ie. Green indicator) and for a Red ash
sequence to happen at the same time. In that case the Red ash will show
as a Yellow or Amber ash.

Cistern Fill Mode

When your new HP or HS pressure system is used to ll toilet cisterns or

troughs, a special feature of the Torrium® controller may be activated. This
special feature is activated when the controller detects three quick stop start
sequences in a short period. When activated the status indicator will glow

“Amber”, and the pump will run on for two minutes before shutting down.
This allows the cistern to be lled with the minimum number of pump cycles.

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 Sterio® control box has

a 2 Amp fuse to protect the circuit. The fuse is not a lightning arrestor and

may not protect the Sterio® if lightning or a very powerful surge hits the

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.

We recommend the use of an RCD or earth leakage circuit breaker on
the power supply to your unit.

Only one fault condition will be indicated at once.
