E. Water Supply and Drain Connections
WARNING
Water supply and drain connections must be installed in accordance with applicable
national, state, and local regulations.
NOTICE
• Normal operating water temperature must be within 45°F to 95°F (7°C to 35°C).
Operation of the ice machine, for extended periods, outside of this normal
temperature range may affect ice machine performance.
• To prevent damage to the ice machine, do not operate the ice machine when
the water supply is off, or if the pressure is below 10 PSIG. Do not run the ice
machine until the proper water pressure is reached.
• Connect to potable water supply only. Do not connect to a hot-water supply.
• In areas where water damage is a concern, install in a contained area with a oor
drain.
• Water line installation to the ice machine is not warranted by Hestan.
• Water-hammer issues must be resolved by a qualied plumber before installing
the ice machine. Water hammer can cause ice machine damage that may lead to
water leakage or ooding.
• If using the optional drain pump (AGDP), test its operation every time the ice
machine is cleaned and sanitized. See "IV.E. Optional Drain Pump AGDP" for
details. If the optional drain pump is not operating properly, water could back up
and overow, leading to costly water damage.
• A plumbing permit and services of a licensed plumber may be required in some areas.
• External lters, strainers, or softeners may be required depending on water quality.
Contact your local Hestan Certied Service Representative for recommendations.
• Water supply inlet is 1/2" female pipe thread (FPT).
