On InstallationFollow the installation and maintenance document671266 for ES-MEV, paying particular attention to;1.1. The chosen location for installation.a). Mounting the unit using the integral mountingbracket supplied.b). Mount the unit on a non reverberant surface.c). The unit can be mounted at any angle.d). Make sure that when the unit is mountedsufficient space is left around the unit formaintenance and the fixing of the ducting.e). If installed with flexible duct special care/consideration should be made to prevent theduct being closed off, cracked or twisted,introducing a high resistance on the system.1.2. Electrical.a). Pay particular attention to electricalconnections referring to the I&M for correctmethod.b). Isolation of the unit and any switched livecircuits should be achieved through the sameisolator.230V Switched live1.3 Setting to workWhen initially powered the ES-MEV will selfcalibrate, it will try to achieve the duties set bythe MAX and MIN set points.The calibration process can take around 2 minutesand is as follows:■ Unit runs to full speed. (Faster than the maxset point).■ The unit will slow down and eventually stop.■ A 10 second wait.■ It will restart and run at ¼ speed.■ The unit then settles to the MIN speed.If, during this process the red LED should illuminate,ensure there are no switched live or boost signalspresent.Upon completion of the calibration process apply aswitched live (SL), the fan speed and duty shouldincrease to that of the MAX set point.When testing a systema). The ‘dial a duty’ set points should be positionedwith the MAX at MAX and MIN at MIN, i.e.giving the widest possible speed control range.b). On an existing installation it is important toobserve and note these duty positions shouldit be necessary to return to them later.c). The SL run on should be set to minimum toreduce the run on time during test, it isimportant to note the position set should it benecessary to return to it later.Circuit board connections.
