C. Location This icemaker is not intended for outdoor use. Normal operating ambient temperature should be within +45°F(7°C) to +100°F(38°C); Normal operating water temperature should be within +45°F (7°C) to +90°F (32°C). Operation of the icemaker, for extended periods, outside of these normal temperature ranges may affect production capacity.
Page 12: Electrical Connection
E. Electrical Connection 1. Electrical connection must be made in accordance with the instructions on a "WARNING" tag, provided with the pig tail leads in the junction box. 2. This icemaker requires a ground that meets the national and local electrical code requirements.
