Never use PVC pipe directly connected to unit. PVC pipe and fittings can 
be used after 90º metal elbows are connected to the inlet and outlet of the 
chamber eg. brass fittings. Larger diameter pipe may be used to minimise 
resistance to flow, but maximum flow rates should not be exceeded, as 
correct water treatment cannot be assured at higher flows. If flows may 
exceed the design maximum, install a flow restriction device.

At no stage should the UV system be operating without water present inside the 
chamber. Damage to the system could result.
If the system is bypassed, the unit should be switched off to avoid over heating  
and alarming.

LED Indicators

The Steriflo 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 Steriflo 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.
Flashing of the red LED indicates normal operation and the lamp countdown timer  
is operating.

Should the unit alarm, power to the pump will be interrupted ensuring safe 
water is always supplied. Manual overriding of this feature is available by 
briefly pressing the reset button once for emergency water supply.

If pump outlet is not required retain plastic guard supplied on pump outlet.

Alarms

1. Intermittent beeping indicates that the lamp requires changing and can be silenced 

for 24 hours by pressing the reset button to allow for a new lamp to be obtained. It 
is good practice to have a spare lamp on hand to ensure a quick changeover.

2.  In the event of a system failure or bad connection, the alarm will continuously 

sound and the red LED will light up. Power to the pump connection (if used) will be 
disabled to ensure only treated water is delivered. For emergency water supply, 
the reset button can be pressed, but note that the water may be unsafe.

The alarm function or lamp can be checked as follows:
1.  Switch off mains power to the lamp power supply and remove plug from outlet.
2.  Disconnect the lamp.
3.  Allow one minute delay to reset the lamp ballast.
4.  Reconnect the existing or replacement lamp.
5.  Reconnect the power.
