Disinfection of Cold Supply
The Rada Outlook is able to disinfect
the cold supply pipes as well as the
digital mixing valve and each of the
outlets. In order for this to happen,
the cold supply must have a suitable
by-pass device to allow a feed from
the hot supply (to disinfect the entire
cold water supply of a building, the
by-pass should be located close
to the water meter or the stand
pipe). The by-pass diverts the hot
water flow through the cold supply
pipe temporarily for the disinfection
cycle. Once this by-pass is active,
the Rada Outlook can be set to
automatically disinfect through the
cold supply.
The thermal disinfection of cold
supply pipes is dependent upon local
or national legislation and may not
be required in every installation. The
cold supply disinfection is generally
required when the system is either used for the first time or has not been in use
for a prolonged period (to make sure that the cold supply pipes are free from high
levels of bacteria).
1.
Close cold supply isolator valve.
2.
Turn by-pass valve to allow hot water to flow into cold pipework.
3.
Operate Cold Supply Disinfection routine.
4.
Turn by-pass valve to stop water entering cold pipework.
5.
Open drain valve and remove residual hot water from cold pipework to valve.
6.
Close drain valve and re-open cold supply isolator valve.
7.
Allow up to 1 hr for Outlook valve brass material to cool.
8.
Operate as normal.
WARNING!
•
As with any type of thermal disinfection process, the feature is not to be used
unless adequate systems are in place to ensure that the area is clear of any
persons prior to and during the disinfection process. This includes any exposed
or uninsulated pipework that will reach an unsafe temperature.
