• Re-install the housing.
• 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 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 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
unless the system is manually reset as outlined on page 10 of this manual.
