A. Location

1. Icemaker

NOTICE

• This icemaker is not intended for outdoor use. Normal operating ambient temperature must be within 45°F to 100°F (7°C to 38°C); Normal operating water temperature must be within 45°F to 90°F (7°C to 32°C). Operation of the icemaker, for extended periods, outside of these normal temperature ranges may affect icemaker performance.

• This icemaker will not work at sub-freezing temperatures. To prevent damage to the water supply line, drain the icemaker if the air temperature is going to go below 32°F (0°C). See "IV. Preparing the Icemaker for Periods of Non-Use."

• The icemaker should not be located next to ovens, grills, or other high heat producing equipment.

• Allow 6" (15 cm) clearance at rear, right side, and top for proper air circulation and ease of maintenance and/or service should they be required. Allow 28" (71 cm) clearance on left

side for removal of cube guides.

• The location must provide a rm and level foundation for the equipment.

2. Remote Condensing Unit

NOTICE

• The remote condensing unit is intended for outdoor use. Normal operating ambient temperature must be within -20°F to 122°F (-29°C to 50°C). Operation of the remote condensing unit, for extended periods, outside of this normal temperature range may affect performance.

• The maximum line set length is 66' (20 m). No refrigerant charge adjustment is necessary.

• The maximum vertical distance between the remote condensing unit and icemaker is 33' (10 m) above or 10' (3 m) below the icemaker. These distances are measured tting to tting. See Fig. 1.

• If the vertical distance between the remote condensing unit and the icemaker is greater than 20' (6 m) (not to exceed 33' (10 m)), an "S" oil-trap (5/8"OD copper tubing) must be installed in the suction line. The "S" oil-trap must be located halfway between the icemaker and remote condensing unit. This ensures sufficient oil return to the compressor.

The remote condensing unit must be positioned in a permanent site under the following guidelines:

• A rm and at site.

• A dry and well ventilated area with 24" (61 cm) clearance in both front and rear for proper air circulation and ease of maintenance and/or service should they be required. See Fig. 2.
