2. Water & Drain Hookup (4-min video)

1. Shut off main water and bleed pressure.
2. Route 1/4″ line from cold-water tee to ice-maker valve; avoid kinks.
3. Hand-tighten compression nut, then add 1/4-turn with wrench.
4. For drains: maintain 1/4″ per-foot slope or mount pump per manual.

3. Electrical & GFCI Requirements

Indoor units pull 2–4 amps on a dedicated 120 V, 15 A circuit. NEC 210.8(B) mandates GFCI protection for outlets in wet-bar or kitchen bases. Test with a GFCI tester after wiring.

4. Ventilation & Fitment

Level the cabinet with adjustable feet to prevent ice-level sensor errors.

5. Testing & Initial Flush Cycle

1. Open water valve; check all joints for leaks.
2. Plug unit in, press Clean cycle—most brands take 20 min.
3. Discard the first full ice batch; it may taste metallic.
