Installation InstructionsGENERAL INSTALLATIONThis shower valve is a mixing device so the inlet pressures must bereasonably balanced.For ease of maintenance it is recommended that isolation valves arefitted to the inlet feeds.All supply pipes MUST be thoroughly flushed to remove any debris priorto making any connection to the valve. Failure to do so could result indamage or low flow from the mixer unit.The valve is supplied with a cover plate as protection during fitting, thisshould remain in place until second fixing.Note: When pressure is higher than 5 bar a pressure reducer is required tobe fitted before the valve.3
