This equipment is not suitable for pool or spa heating.
Water hardness may affect the water heater performance. It is important that the water
heater is installed in water conditions that are suitable for long term operation.
This is a water heating apparatus only and the delivered water quality is dependent upon the
quality of water supplied to this system.
The connection, attachment, integration or general association of other equipment or parts
not specified by the water heater which either directly or indirectly affect the operation or
performance of this equipment could void the warranty.
The manifold pressure is preset at the factory. It is computer controlled and should not need
adjustment.
Please follow the electrical earthing procedure outlined in AS/NZS3000 & AS/NZS3500
before cutting or uncoupling existing metallic pipework.
It should be as close as practical to the hot water outlets to minimise heat loss and cost.
The water heater does not require a fireproof back plate if installed on a timber wall.
