Important Safety Information
Throughout this manual, notices appear to bring your attention to situations which could
result in death, serious injury, damage to the unit, 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 unit or
property.
IMPORTANT Indicates important information about the installation, use, and
care of the unit.
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 install, operate, and
maintain the equipment 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 qualied service technicians should install and service the icemaker.
• Move the control switch to the "OFF" position and turn off the power supply to the
SRK condensing unit before servicing the KMS or SRK. Place the KMS disconnect
(if applicable) in the "OFF" position. Lockout/Tagout to prevent the power supply
from being turned back on inadvertently.
• This icemaker 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 or service switch
with damp hands.
• Do not make any alterations to the unit. Alterations could result in electric shock,
injury, re, or damage to the unit.
• 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 allow children or animals to do so.
Serious injury could occur or the icemaker could be damaged.

WARNING, continued
• Power supply and ground connection are supplied from the SRK remote condensing
For KMS
unit via the wire harness provided. Do not connect the wire harness leads to an
external power source.
• Wire harness 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 severe
damage to equipment.
• THE ICEMAKER MUST BE GROUNDED. Failure to properly ground the icemaker
could result in death, serious injury, or damage to equipment.
For SRK
• 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 to equipment.
• The remote condensing unit requires an independent power supply of proper
capacity. See the nameplate for electrical specications. Failure to use an
independent power supply of proper capacity can result in a tripped breaker, blown
fuses, 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 "III.C. Preparing the Icemaker for Periods
of Non-Use."
• Do not place objects on top of the icemaker.
• The dispenser unit/storage bin is for ice use only. Do not store anything else in the
storage bin.

II. Installation and Operating Instructions
WARNING
• The icemaker and condensing unit must be installed in accordance with
applicable national, state, and local codes and regulations.
• Failure to install, operate, and maintain the equipment 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

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 "III.C. 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 and sides 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 icemaker performance.
The icemaker must be coupled with the appropriate remote condensing unit as listed
below.

• The maximum line set length is 66 feet.
• The maximum vertical distance between the remote condensing unit and icemaker is
33feet above or 10 feet below the icemaker. These distances are measured tting to tting.
See Fig. 2.
• If the vertical distance between the remote condensing unit and the icemaker is greater
than 20 feet (not to exceed 33 feet), an "S" oil-trap (3/4" 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.
