Notes:
1) The addition of chlorine (bleach) to a hot water tank that has in the past been fed with untreated raw water
with high levels of other contaminants (iron, manganese, hydrogen sulphide, organics, etc.) will result in
oxidation of these contaminants and may require repeated flushing of the hot water tank. This contingency
must be dealt with independently under the start-up procedure for any other conditioners that may form a part
of the pre-treatment for the UV unit.
2) The above cleaning procedure will result in a massive chlorine residual far in excess of the 0.5 to 1.0 mg/L
typically present in municipally chlorinated water and of a magnitude consistent with the minimum 50 mg/L
chlorine solution recommended for the cleaning of distribution systems known to be contaminated. Do not
consume water until complete system has been flushed
.
3) As the monitored systems include a 254nm UV intensity monitor, note that the introduction of the bleach
solution required for cleaning will trigger a temporary low UV condition. This is due to the fact that the bleach
physically “clouds” the raw water. Once the bleach runs through the system, the alarm condition will return to
normal. During this sanitization process, the audible alarm condition on the controller can be temporarily
deferred by pressing the “RESET” switch for 5 seconds. By doing this, the audible alarm will be silenced. The
system will display
on the controller LED. This condition will remain for 12 hours unless the system is
manually reset as outlined on page 10 of this manual.

4.1 Replacing UV Lamp
Lamp replacement is a quick and simple procedure requiring no special tools. The UV lamp must be replaced after 9000
hours of continuous operation (approximately one year) in order to ensure adequate performance.
WA R N I N G
•
Always disconnect power before performing any work on the UV system.
•
Always shut-off water flow and release water pressure before servicing.
•
Regularly inspect your UV system to ensure that the power indicators are on and no alarms are present.
•
Replace the UV lamp annually (or biennially if seasonal home use) to ensure maximum performance.
•
Always drain the chamber when closing a seasonal home or leaving the unit in an area subject to freezing temperatures.
N O T I C E
•
Reset lamp life timer after lamp replacement. Refer to
Section 5.1.3
. Refer to
www.lamprecycle.org
for lamp disposal.
•
Do not use water during replacement of UV lamp.
