INSTALLATION

HOT WATER CONNECTIONS

Pressure reducing valve

If the mains water pressure is greater than 6 bar, a pressure reducing
valve must be fitted.

Expansion relief valve

The tank expansion relief valve must be ACV approved and
calibrated to a maximum of 7 bar. The valve discharge must be
connected to the drain.

Hot water expansion vessel

We recommend installing a hot water expansion vessel.

Hot water circulation

If the tank is situated a long way from the point of use, then installing
a recirculation loop can provide a faster supply of hot water to the
outlets.

Temperature and pressure relief valve

If using the HeatMaster as an unvented hot water unit, in some
countries, a temperature and pressure relief valve must be fitted -
consult your ACV stockist for assistance.

DANGER!
As a safety measure, we strongly advise
installing a thermostatic mixer to prevent the
risk of burns

Example of h storage connection

Recommended for applications requiring a high peak flow.

Example of series connection

Preferable for high temperature applications with up to three units.

Example of parallel connection

Recommended for applications with a high continuous flow.
