- Re-install the housings.
- Turn on the cold water
supply.
- Open each faucet and all
water openings until you
smell the bleach and then
close the faucets.
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 disinfection 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 disinfection of distribution sys-
tems 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 disinfection 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.
WARNING:
- Always disconnect power before performing any work on the disinfection system.
- Always shut-off water flow and release water pressure before servicing.
- Regularly inspect your disinfection 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
disinfection.
- Always drain the chamber when closing a seasonal home or leaving the unit in an area
subject to freezing temperatures.
