Installation
Preparing your system
Before installing your new Aquashield Centurion, please read all instructions
carefully as failures caused by incorrect installation or operation are not
covered by the guarantee. Your Ultra Violet water treatment system is designed
to handle clean water. The system should not be used for any other purpose
without specic referral to Davey. The use of the system with ammable,
corrosive and other materials of a hazardous nature is specically excluded.
On removing your Aquashield Centurion system from its carton you should check all
components to ensure all are present and have not been damaged in transportation.
Choosing a Site
To protect your Davey Aquashield Centurion from the weather, make sure the site is
water proof, frost free and has adequate ventilation. Choose a site with a structurally
appropriate mounting position on the wall. Allow a chamber length space above the
unit for removal of the lamp and sleeve from the Sterio during servicing and 100mm
below the cartridges for maintenance.
The unit can be mounted with water ow from left to right, or right to left as
the plumbing requires. The Sterio control box may need to be moved. Allow
for drainage, to avoid damage to ooring etc. that over time may occur during
maintenance or from leaking pipe joints or seals.
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 Sterio control box has a fuse to protect
the circuit. The fuse is not a lightning arrestor and may not protect the Sterio 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.
Power Connection
Connect lead to power supply designated on control box label. Do not use long
extension leads as they may cause substantial voltage drop and/or poor lamp
performance. The stainless steel chamber is connected to earth as supplied and this
connection must always be used during operation.
The control box has a female power socket that can be used to power a pump. In the
event of a lamp failure, power to the pump will be shut off to ensure untreated water
is not delivered.
Ensure flow rate of the pump does not exceed rated flow of the UV
system or maximum rated current draw of 5.7A.
CAUTION: The supply cord is necessary for lamp changing. The three pin
supply plug must remain accessible after installation. If installed to xed
wiring without the plug a two pole switch must be tted and its ON and OFF
positions shall be marked.
