3. INSTALLATION - GENERAL
3.1. Suitability
The product is suitable for domestic hot water systems where the cold mains water supply
has a maximum supply pressure of 0.9 MPa. Reduced performance is available at lower
pressures, but the product is not suitable for pressures lower than 0.15 MPa and a flow rate
of 20 litres per minute. The neccessary safety equipment to comply with all national
legislation is available for purchase from Rointe.
3.2. Water supply
The water supply to the cylinder should be potable water direct from a public mains water
supply with any water treatment equipment functioning correctly. For optimum performance
the unit should be fed via a 15 mm or 22 mm diameter supply pipe direct from the mains
water entry point to the property and supplies a maximum pressure of 0.9 MPa. The unit
can operate with a minimum supply pressure of 0.15 MPa and a flow rate of at least 20 litres
per minute, but flow from the outlets will be low if several outlets are used simultaneously.
The cylinder control equipment is factory set to limit the system operating pressure to 0.3
MPa. The maximum supply pressure into the pressure-reducing valve is 0.9 MPa.
3.3. Taps and fittings
All taps and fittings incorporated in the unvented system should have a rated operating
pressure of 0.7 MPa or above.
