Requirements
• Before starting installation the WARNINGS
6) should be read and fully understood. If in doubt, or in need of further guidance,
please call Zip Customer Service on 0345 6 005 005
•
Installations must comply fully with UK Water Regulations, Building regulations part G3
and any Local Authority requirements.
•
The electrical installation including earthing and cross bonding should comply with the
current IEE regulations and any Local Authority requirements.
•
The Zip Aquapoint III is designed for connection direct to the incoming mains water
supply and accommodation must be made for the expanded water that will occur
with each heating cycle. Regulations permit expanded hot water to be accommodated
within the supply pipe work provided that no check valve, stop valve with loose jumper
or other fitting can prevent reverse flow. [See diagram 1, (Fig.2) on page 12].
•
Where the expanded water cannot be accommodated in the pipe work and the static
water supply pressure is under 3.5 bar, fit accessory pack AQ2 (expansion vessel and
check valve). Where static water pressures are likely to exceed 3.5 bar fit accessory
pack AQ2 and AQ3 (pressure reducing valve and line strainer).[See diagrams 2&3
(Fig.2) page 12].
•
If required a temperature and pressure relief valve (accessory AQ1) can be used with any
installation by fitting securely into the locating point provided.
•
The 6 bar expansion relief valve must be fitted on the cold water supply.
Under no circumstances should the expansion relief valve be installed in an inverted
position as fouling of the seat caused by deposits may prevent it from operating correctly.
The safety relief valve connections should not be used for any other purpose and no
valve should be fitted between the expansion relief valve and the storage cylinder.
• The installations must comply fully with UK Water Regulations, Building regulations
part G3 and any Local Authority requirements. The point of discharge must be in a
safe and visible position. The connection should be made using 15mm pipe having a
continuous fall to a maximum length of 3 metres. It shall not have more than 3 right-
angled bends. If a waste connection in excess of 3 metres is necessary, the pipe
diameter should be 22mm with continuous fall and no more than 4 right-angled
bends with a maximum resistance to flow equivalent to 9 metres of straight pipe.
•
An isolating valve must be fitted to the cold water supply.
•
Valves and fittings must be of a type required by the Water Supply Regulations.
