6. If required a Temperature and Pressure relief valve (accessory AQ1) can be
used with any installation by fitting securely into the locating point provided.
7. 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.
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.
8. The drain connection from the expansion relief valve and the T&P valve, if
fitted, must be in accordance with Water Supply Regulations. 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.
9. An isolating valve must be fitted to the cold water supply.
10. Valves and fittings must be of a type required by Water Supply Regulations

base, but if additional support is required, securing screws are supplied that
locate to the rear of the casing.

maintenance.
5. The Zip Aquapoint is not recommended for installation above false ceilings.
