INSTALLATION LOCATE AND LEVELLING ted on the water supply machine. Fix a flexibile palstic pipe (with an inside diameter This icemaker is designed to be installed in rooms of 20 mm. and adequate lenght to reach and open with temperatures between 10°C and 40°C. vented drain) to the waste pipe fitting.
Check by means of a tester the continuity of the earth mass from the panels to the plug earth termi- nal board. Mod. N25S ÷ N140 FINAL CHECK a) Check that the supply means voltage corresponds to that stated on the plate of the machine.
