2) Machine Placement
Before installation, use a level to ensure the machine is placed
horizontally. Visually check the top of the machine for level alignment.
a) Place the machine in a clean, well-ventilated indoor area. Avoid
outdoor placement, direct sunlight, or rain exposure.
b) Keep the machine away from heat sources.
c) Ambient temperature should be between 10°C (50°F) and 38°C ( 10
0.4° F). Ensure adequate clearance around the machine for optimal
ice production and heat dissipation.
d) Place the machine on a stable, level surface. Adjust the leveling
during installation.
e) Do not place any objects on top of the ice machine.
f) Maintain sufficient clearance on all sides for proper airflow and
maintenance access.

3) Water Line Connection
● Warning: Connect only to a potable water source that meets local
drinking water standards.
● If using tap water, install a filter to improve water quality. Do not connect
directly to unfiltered tap water. The manufacturer is not responsible for
malfunctions caused by water quality issues.
● Water pressure should be between 0.1–0.4MPa ( 14.5-58.02 Psi). If
pressure exceeds 0.4MPa (58.02 Psi), install a pressure-reducing valve.
● The drain hose relies on gravity flow. Ensure the drain hose has
sufficient elevation or drop.
