General Installation - Mira Activate Series Installation And User Manual

General Installation

All installations shall comply with the Water Supply (Water Fittings) Regulations 1999.
Safe and easy access to the product should be available at all times.
When installing the product in an area not regularly accessed, consideration for potential
leaks must be taken into account. While such events are unlikely, it is advisable to periodically
check the installation for traces of water on or around the product.
If possible, site the product in a location where any leak would be contained or routed to
avoid areas sensitive to water damage.
Isolating valves must be installed to both inlets (supplied) and it is recommended to fit isolators
on the outlet, close to the digital mixing valve for ease of maintenance.
The water supplies to this product must be isolated if the product is not to be used for a long
period of time. If the product or pipework is at risk of freezing during this period they should
also be drained of water.
Important Installation Considerations
• Ensure pumped/gravity digital mixing valves showers are not connected to any mains
water pressure e.g. stored gravity hot water and cold mains water.
• High pressure/combi digital mixing valves should not be fitted to a gravity system.
• The digital mixing valve should not be installed where it can become frozen or be subjected
to ambient temperatures in excess of 50ºC.
• Position the digital mixing valve and power supply so that there is enough room for
maintenance (e.g. removal of the valve lid and servicing filters through removing inlet
pipework) and make sure safe and easy access is available at all times.
Note: The inlet pipework must be flexible enough to allow 25 mm movement to
enable filters to be removed for cleaning and for maintenance of the internal
components. Failure to achieve this may result in service and repair not being
able to be carried out.
• Supply pipework layout must be arranged to minimize the effect of other outlet usage as
shared water supplies may reduce its flow performance upon the dynamic pressures at
the digital mixing valve inlets.
• Avoid installations where air locking could occur.
• Cold water cisterns should hold no less than 230 litres and hot water cylinders no less
than 210 litres (gravity system only).
• To eliminate pipe debris it is essential that water supply pipes must be flushed prior to
connecting the digital mixing valve to the system so debris cannot enter the digital mixing
valve internals.
