1. Before commencing, make sure that the installation conditions comply with the
information given in section: ‘Specifications’ . For Type 3 valves, refer to the
the TMV3 Requirements Manual.
2. Care must be taken during installation to prevent any risk of injury or
damage.
3. Layout and sizing of pipework MUST be such that nominally equal inlet supply
pressures are achieved and effects of other draw-offs are minimised.
4. The Rada Safetherm is suitable for installation as part of a gravity-fed plumbing
system. Minimum inlet pressures of 0.1 bar (1 metre head) are required,
though inlet pressures of 1 bar (10 metre head) are recommended for optimum
performance. If minimum inlet pressures are not available then it will be
necessary to install a pump.
5. When used with a high pressure system above 5 bar maintained pressure ,
a pressure reducing valve will be necessary. It is important that the system
pressures are within the range specified for the Safetherm.
If the system pressure is not known then the system pressure MUST be
measured.
Pressures are those present at the inlet to the appliance either whilst running
(maintained) or in the off state (static). Nearby hot and cold taps connected to
the same proposed feed pipes as the appliance can be used to measure the
static pressure. No other fitting or appliance should be in use at this time.
6. Conveniently situated isolating valves MUST be fitted to the supply
pipework.
7. If the control is to be used with a fully modulating multipoint water heater, fully
modulating combination boiler, thermal store or unvented system an expansion
vessel must be fitted to accommodate the expansion of water in the domestic
hot water supply (this may already be part of the system, check the details on
the boiler/heater or contact the boiler/heater manufacturer).
8. Supply pipes MUST be flushed to clear debris before connecting the control.
Note! The Rada Safetherm is supplied with hot left and cold right inlet
connections as standard.
