• 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 this normal
temperature range may affect icemaker performance.

supply is off, or if the pressure is below 7 PSIG. Do not run the icemaker until the
proper water pressure is reached.

• In areas where water damage is a concern, install in a contained area with a oor
drain.

• Water-hammer issues must be resolved by a qualied plumber before installing
the icemaker. Water hammer can cause icemaker damage that may lead to water
leakage or ooding.
• If using the optional drain pump (HS-0248), test its operation every time the
icemaker is cleaned and sanitized. See "IV.E. Optional Drain Pump" for details.
