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 installation, use, and

care of the appliance.

WARNING

This appliance 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 install, operate, and
maintain the appliance 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 the appliance.

• The appliance must be installed in accordance with applicable national, state, and
local codes and regulations.

• To reduce the risk of electric shock, do not touch the control switch with damp
hands.

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

• Do not make any alterations to the appliance. Alterations could result in electric
shock, injury, re, or damage to the appliance.

• 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.

• Children should be properly supervised around this appliance.

• Do not climb, stand, or hang on the appliance or allow children or animals to do so.
Serious injury could occur or the appliance could be damaged.

• Do not use combustible spray or place volatile or ammable substances near the
appliance. They might catch re.

• Keep the area around the appliance clean. Dirt, dust, or insects in the appliance
could cause harm to individuals or damage to the appliance.

WARNING, continued

Icemaker

• Do not connect the icemaker to an external power source. Icemaker power supply
and ground connection are supplied from the remote condensing unit via the wire
bundle provided with the remote condensing unit.

• Wire bundle routing (conduit) and disconnect (if required) must meet national, state,
and local electrical code requirements. Failure to meet these code requirements
could result in death, electric shock, serious injury, re, or damage.

• THE ICEMAKER MUST BE GROUNDED. Failure to properly ground the icemaker
could result in death or serious injury.

Remote Condensing Unit

• Remote condensing unit electrical connection must be hard-wired and must meet
national, state, and local electrical code requirements. Failure to meet these code
requirements could result in death, electric shock, serious injury, re, or damage.

• The remote condensing unit 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.

• THE REMOTE CONDENSING UNIT MUST BE GROUNDED. Failure to properly
ground the remote condensing unit could result in death or serious injury.

NOTICE

• Follow the water supply, drain connection, and maintenance instructions 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).

• 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 "IV. Preparing the Icemaker for Periods of
Non-Use."

• Do not place objects on top of the appliance.

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

I. Specications

A. Electrical and Refrigerant Data

The rating label (KMS) and nameplate (KMS and SRK) provide electrical and refrigerant
data. The rating label can be seen by removing the front panel. The nameplate is located
on the rear panel of the icemaker and on the side panel of the remote condensing unit.
Forcertication marks, see the nameplate.
We reserve the right to make changes in specications and design without prior notice.

II. Installation and Operating Instructions

WARNING

• The icemaker and remote condensing unit must be installed in accordance with
applicable national, state, and local codes and regulations.

• Failure to install, operate, and maintain the appliance in accordance with this
manual will adversely affect safety, performance, component life, and warranty
coverage and may result in costly water damage.

• CHOKING HAZARD: Ensure all components, fasteners, and thumbscrews
are securely in place after installation. Make sure that none have fallen into the
dispenser unit/ice storage bin.

A. Location

1. Icemaker

NOTICE

• This icemaker is not intended for outdoor use. Normal operating ambient
temperature must be within 45°F to 100°F (7°C to 38°C); 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 these normal temperature ranges may
affect icemaker performance.

• This icemaker will not work at sub-freezing temperatures. To prevent damage
to the water supply line, drain the icemaker if the air temperature is going to go
below 32°F (0°C). See "IV. Preparing the Icemaker for Periods of Non-Use."

• The icemaker should not be located next to ovens, grills, or other high heat producing
equipment.

• Allow 6" (15 cm) clearance at rear, sides, and top for proper air circulation and ease of
maintenance and/or service should they be required.

• The location must provide a rm and level foundation for the equipment.

2. Remote Condensing Unit

NOTICE

• The remote condensing unit is intended for outdoor use. Normal operating ambient
temperature must be within -20°F to 122°F (-29°C to 50°C). Operation of the
remote condensing unit, for extended periods, outside of this normal temperature
range may affect performance.

• The maximum line set length is 66' (20 m). No refrigerant charge adjustment is
necessary.

• The maximum vertical distance between the remote condensing unit and icemaker
is 33' (10 m) above or 10' (3 m) below the icemaker. These distances are measured
tting to tting. See Fig. 1.

• If the vertical distance between the remote condensing unit and the icemaker
is greater than 20' (6 m) (not to exceed 33' (10 m)), an "S" oil-trap (5/8"OD
copper tubing) must be installed in the suction line. The "S" oil-trap must be
located halfway between the icemaker and remote condensing unit. This ensures
sufficient oil return to the compressor.

The remote condensing unit must be positioned in a permanent site under the following
guidelines:

• A rm and at site.

• A dry and well ventilated area with 24" (61 cm) clearance in both front and rear for proper
air circulation and ease of maintenance and/or service should they be required. See Fig. 2.
