Plumbing Connections
The Storage Tank is installed and connected to the plumbing installation as normal and
detailed in the Conergy installation instructions supplied with the water heater. The
household plumbing connections should be made to the tank socket fittings on the left
side of the storage tank. This leaves the right side fittings free for connection to the solar
collector system.
7.2.1
Cold water connection
A check valve and a stop cock must be fitted to the cold water supply pipe work.
1.
The cold water connection is made at the
connection marked “Cold Water Inlet”.
2.
Where the water supply pressure is greater than or likely to exceed 550 kPa at
any time, a 500 kPa pressure reducing
valve must be fitted to limit the supply
pressure.
A breach of this requirement may void the warranty in the event of damage caused
by excessive pressure.
7.2.2
Cold water expansion relief valve
Fit the 600 kPa expansion control valve, supplied in the Parts Box, in the cold water
supply pipe after the check valve, stop cock and (if required) pressure limiting valve.
7.2.3
Hot water connection
Use the ¾” BSP fitting, supplied in the Parts Kit, to connect the hot water supply to the
storage tank outlet connection.
