Important Safety Information

Throughout this manual, notices appear to bring your attention to situations which could

result in death, serious injury, damage to the appliance, or damage to property.

WARNING Indicates a hazardous situation which could result in death or

serious injury.

NOTICE Indicates a situation which could result in damage to the

appliance or property.

IMPORTANT Indicates important information about the use and care of the

appliance.

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. Failure to service and maintain the icemaker in

accordance with this manual will adversely affect safety, performance, component life,

and warranty coverage and may result in costly water damage.

To reduce the risk of death, electric shock, serious injury, or re, follow basic

precautions including the following:

• Only qualied service technicians should install and service this icemaker.

• This icemaker must be installed in accordance with applicable national, state, and local

codes and regulations.

• This icemaker requires an independent power supply of proper capacity. See the

nameplate for electrical specications. Failure to use an independent power supply of

proper capacity can result in a tripped breaker, blown fuse, damage to existing wiring,

or component failure. This could lead to heat generation or re.

• THIS ICEMAKER MUST BE GROUNDED: This icemaker is equipped with a

NEMA5-15 three-prong grounding plug to reduce the risk of potential shock

hazards. It must be plugged into a properly grounded, independent 3-prong wall outlet.

If the outlet is a 2-prong outlet, it is your personal responsibility to have a qualied

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 icemaker.

• To reduce the risk of electric shock, do not touch the power switch or plug with damp

hands.

• Do not use an icemaker with a damaged power cord. The power cord should not be

altered, jerked, bundled, weighed down, pinched, or tangled. Such actions could result

in electric shock or re. To unplug the icemaker, be sure to pull the plug, not the cord,

and do not jerk the cord.

• Do not make any alterations to the icemaker. Alterations could result in electric shock,

injury, re, or damage to the icemaker.

• Do not place ngers or any other objects into the ice discharge opening.

6

WARNING, continued

• This appliance is not intended for use by persons (including children) with reduced

physical, sensory, or mental capabilities, or lack of experience and knowledge, unless

they have been given supervision or instruction concerning use of the appliance by a

person responsible for their safety.

• Young children should be properly supervised around this appliance.

• Do not climb, stand, or hang on the icemaker or icemaker door or allow children or

animals to do so. Serious injury could occur or the icemaker could be damaged.

• Be careful not to pinch ngers when opening and closing the door. Be careful when

opening and closing the door when children are in the area.

• Do not use combustible spray or place volatile or ammable substances near the

icemaker. They might catch re.

• Keep the area around the icemaker clean. Dirt, dust, or insects in the icemaker could

cause harm to individuals or damage to the icemaker.

NOTICE

• Protect the oor when moving the icemaker to prevent damage to the oor.

• Follow the instructions in this manual carefully to reduce the risk of costly water

damage.

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

• Install the icemaker in a location that stays above freezing. Normal operating ambient

temperature must be within 45°F to 100°F (7°C to 38°C).

• If using the optional drain pump (HS-0248), test its operation every time the icemaker is

cleaned and sanitized. See "IV.E.2. Drain Pump Check" for details. If the optional drain

pump is not operating properly, water could back up and overow, leading to costly

water damage.

• To help ensure that the storage bin drain remains clear, follow the instructions in "VI.C.

Storage Bin Drain" once every 3 months or as often as necessary for conditions. If

the storage bin drain becomes clogged, water could build up in the bin and overow,

leading to costly water damage.

• If water collects in the bin and will not drain, turn off the icemaker and close the water

supply line shut-off valve. Locate and resolve the issue.

• To help protect against unseen water issues, this icemaker features a drip tray and

emergency overow hose. See Fig. 1. If there is water in the drip tray, coming out of

the reservoir emergency overow hose, or seeping from the base of the icemaker, turn

off the icemaker and close the water supply line shut-off valve. Locate and resolve the

issue. Failure to do so could lead to costly water damage.

• Do not leave the icemaker on during extended periods of non-use, extended absences,

or in sub-freezing temperatures. To properly prepare the icemaker for these occasions,

follow the instructions in "VII. Preparing the Icemaker for Periods of Non-Use."

• Keep ventilation openings, in the appliance enclosure or in the built-in structure, clear

of obstruction.

• Do not place objects on top of the icemaker.

• The storage bin is for ice use only. Do not store anything else in the storage bin.

B. Sequence of Operation

1. Auxiliary Codes A-1 and Earlier

After the power switch is placed in the "ON" position, the steps in the sequence are as

outlined below.

a) Freeze Cycle

BCH, GM, FM, CR, and Comp energize. NOTICE! Some units contain a sticker that

states: "The bin control heater has been disconnected. DO NOT reconnect the

bin control heater." In this case, leave BCH disconnected or replace BC assembly

with 3A2561A03. Ice production starts 4 to 6minutes after Comp energizes depending

on ambient and water conditions. The freeze cycle continues until BC shuts down the

icemaker or power is turned off to the icemaker. Rell: The oat-operated WV allows

water into the reservoir as needed to continue the icemaking process. If the water supply

is cut off or GM stops during the freeze cycle, the cold evaporator temperature causes

STS to open and de-energize all components except BCH and optional drain pump

HS-0248.

b) Bin Control Thermostat Shutdown

Ice lls storage bin to level of BC. BC opens within 10 seconds after ice contact. When

BC opens, BCH remains energized. GM, FM, CR, and Comp de-energize. When ice level

lowers and BC closes, the icemaker starts operating again.

2. Auxiliary Codes A-2 and Later

After the power switch is placed in the "ON" position, the steps in the sequence are as

outlined below.

a) Fill Cycle

LF/S and UF/S open, BCH and WV energize. LF/S closes. Nothing happens at this time.

Reservoir continues to ll until UF/S closes.

b) Freeze Cycle

UF/S closes. BCH remains energized. WCR, TDR, GM, FM, CR, and Comp energize. WV

de-energizes. Ice production starts 4 to 6minutes after Comp energizes depending on

ambient and water conditions. F/S controls WV to rell as needed during the freeze cycle.

The freeze cycle continues until BC shuts down the icemaker or power is turned off to

the icemaker. Rell: As ice is produced, the water level in the reservoir drops and UF/S

opens. When UF/S opens, a latching circuit through LF/S and WCR keeps WCR, TDR,

GM, FM, CR, and Comp energized. When LF/S opens, WCR de-energizes, cutting power

to TDR terminal #5 (O wire) and starting FT. WV energizes. Water lls the reservoir, UF/S

closes. WCR energizes, restoring power to TDR terminal #5 (O wire) and resetting FT.

WV de-energizes. If UF/S remains open longer than 90 seconds, FT terminates, cutting

power to TDR terminal#9 (R wire). GM, FM, CR, and Comp de-energize. WV remains

energized until UF/S closes.

c) Bin Control Thermostat Shutdown

Ice lls storage bin to level of BC. BC opens within 10 seconds after ice contact. When

BC opens, BCH remains energized. WCR, TDR, GM, FM, CR, and Comp de-energize.

When ice level lowers and BC closes, the icemaker starts operating again.
