Fittings:
All fittings and pipework used to attach the water cooler to the mains water supply
must be approved to the relevant local standards. No standards apply in Ireland, so it
is recommended that fittings approved to the Water Supply (Water Fittings)
regulations in the UK are used. Such fittings will be approved by WRAS or KIWA.
These fittings can be purchased from OASIS or OASIS can refer you to reputable
suppliers of Point-of-Use parts in your market place.
Installation:
Each installation must include the following components
•
An isolating and non return valve must be fitted at the point of connection to
the water supply.
•
An anti leak device must be fitted at the point of connection to the water
supply downstream of the isolating and non return valves.
•
Pressure limiting devices should be installed to protect the cooler and feed
pipework from water pressure surges in locations where they may occur
•
Each cooler must have an independent isolating tap. This is intended so
that the cooler can be replaced without draining long lengths of piping
The following general guidelines apply to the pipework
•
Pipework should avoid light fittings and electrical and gas piping
•
Pipework in public view should be securely and neatly fixed.
•
All pipework should be accessible and clearly labeled.
•
Pipework should be lagged when necessary to avoid freezing or high
temperatures.
The customer should be informed in writing of the location of all isolation valves
Sanitisation:
EPDWA guidelines state:
•
All coolers must be sanitized before commissioning
•
When a customer signs up to the sanitisation program, the cooler should be
sanitized every 6 months
•
Sanitisation should be carried out in accordance with the manufacturer’s
instructions – see attached documents.
