WARNING

This icemaker should be destined only to the use for which it has been expressly conceived. Any other use should be considered improper and therefore dangerous. The manufacturer cannot be held responsible for injury or damage resulting from improper, incorrect, and unreasonable use.

To reduce the risk of death, electric shock, serious injury, or fire, follow basic precautions including the following:

•This unit should be disassembled or repaired only by qualified service personnel to reduce the risk of electric shock, injury, or fire.

•Move the power switch to the "OFF" position. Unplug the icemaker from the electrical outlet and turn off the power supply to the condensing unit before any servicing is undertaken. Place the disconnect (if applicable) in the off position. Lockout/Tagout to prevent the power supply from being turned back on inadvertently.

•Make sure the icemaker power switch is in the "OFF" position before plugging in or unplugging the icemaker to reduce the risk of electric shock.

•Do not make any alterations to the icemaker or condensing unit. Alterations could result in electric shock, injury, fire, or damage to the units.

For FS

•The icemaker requires an independent power supply of proper capacity. See the nameplate for electrical specifications. Failure to use a properly sized breaker or fuse can result in a tripped breaker, blown fuse, or damage to existing wiring. This could lead to heat generation or fire.

•THIS UNIT MUST BE GROUNDED. This unit is equipped with a 3‑prong grounding plug to reduce the risk of potential shock hazards. It must be plugged into a properly grounded, independent wall outlet. If the outlet is a

2-prong outlet, it is your personal responsibility to have a qualified electrician replace it with a properly grounded, independent 3-prong wall outlet. Do not remove the ground prong from the power cord and do not use an adapter plug.

•Do not use an extension cord.

•To reduce the risk of electric shock, make sure the power switch is in the "OFF" position before plugging in or unplugging the unit.
