LAE electronic MP1 Series Instructions For Installation And Use Manual

INSTRUCTIONS FOR INSTALLATION AND USE.
MP1
Thank you for having chosen an LAE electronic product. Before installing the instrument, please read this instruction booklet carefully in order to
ensure safe installation and optimum performance.
1. INSTALLATION
1.1 The MP1-15, size 77x35x77 mm (WxHxD), is inserted into the panel through a hole measuring 71x29 mm and is fixed by means
of the suitable clips, by pressing gently. If fitted, check that the rubber gasket adheres to the panel perfectly, in order to prevent debris
and moisture infiltration to the back of the instrument.
1.2 The instrument should work with room temperatures between -10°.. +50°C and relative humidity between 15%.. 80% inclusive.
Supply voltage, switched powers and connection set-up should scrupulously comply with the indications given on the container. To
reduce the effects of electromagnetic disturbance, keep the sensor and signal cables well separate from the power wires.
1.3 The sensor T1 measures the air temperature and activates in the thermostat control cycle; it should be placed inside the appliance
in a point that truly represents the temperature of the stored product. If fitted and enabled, (T2=YES), the sensor T2 measures the
evaporator temperature, and should be placed where there is the maximum formation of frost.
CAUTION: should the relays have to switch a heavy load frequently, it is advisable to contact the manufacturer for indications on the lifetime of
the contacts.
Whenever products must be kept within very severe specifications or the products have considerable value, the use of a second instrument is
recommended, which activates upon or warns of any malfunction.
