INSTALLATION INSTRUCTIONS
Overview
Remote condenser systems are comprised of three components: the
pre-charged remote condenser, the pre-charged ice maker, and the
pre-charged line set. For installation of the ice making head, reference
the installation instructions supplied with the ice maker.
Select a Location
The proper selection of a location for the remote condenser is critical to
the performance and longevity of the ice-making system. Please follow
these guidelines when choosing a location for your remote condenser:
• This product shall not be installed within 20 ft [6.1 m] of any building
opening. If this product is enclosed within a penthouse, lean-to,
or other open structure, natural or mechanical ventilation shall be
provided. Refrigerant circuit access ports located outdoors shall be
secured to prevent unauthorized access.
• The remote condenser shall not be used in areas where sucient
airow is not available. It shall not be installed in the same area where
the ice maker is installed.
• Choose a location which is protected from extremes of dirt, dust, rain,
hail, sun, and prevailing winds.
• Consider the eect of the heat being rejected into the condenser
installation area and ensure this additional heat is acceptable.
• Vertical air discharge requires at least 48 inches [1.2 m] clearance
above the condenser.
• Condenser must have a minimum clearance of 18 inches [457 mm] on
three sides. One side must be open for proper ventilation.
• Install condenser with included legs. Condenser must have a minimum
clearance of 15 inches [381 mm] between the mounting surface and
the condenser base.
• Condenser must be installed on a level surface.
• Condenser location higher than the ice maker is preferred.
• Installation location may be aected by local building codes. Be sure to
follow all applicable local, state, and national building, plumbing, and
electrical codes.
Location Rise and Run Limits
Use the following information for planning the placement of the remote
condenser relative to the ice machine.
The remote condenser location must not exceed ANY of the following.
Congurations that do not meet these requirements must receive written
authorization from the manufacturer.
• Maximum rise from the ice machine to the remote condenser: 35
physical feet [10.67 physical meters]
• Maximum drop from the ice machine to the remote condenser: 10
physical feet [3.05 physical meters]
• Maximum line set length: 75 physical feet [22.86 physical meters]
• Maximum calculated line set length: 100 feet [30.48 m]
Determine the calculated line set length using the formulas below:
Calculated line set length = Drop + Rise + Horizontal Run
Drop = dd x 6.6 where dd = drop distance in ft or m
Rise = rd x 1.7 where rd = rise distance in ft or m
Horizontal Run = horizontal distance in ft or m
IMPORTANT: Do not route a line set that rises, then falls, then rises. Do
not route a line set that falls, then rises, then falls. See diagram below.

Equivalent Run Calculation Example: Rise
Calculated line set length = (Rise x 1.7) + (Drop x 6.6) + Horizontal Run
Calculated line set length = (35 x 1.7) + (0 x 6.6) + 40
Calculated line set length = 99.5 ft
Calculated line set length must not exceed 100 ft
Equivalent Run Calculation Example: Drop
Calculated line set length = (Rise x 1.7) + (Drop x 6.6) + Horizontal Run
Calculated line set length = (0 x 1.7) + (10 x 6.6) + 34
Calculated line set length = 100 ft
Calculated line set length must not exceed 100 ft

Plan Refrigerant Tubing Route
Plan the route of the refrigeration tubing between the ice maker and the
remote condenser. Follow these guidelines to ensure proper performance
and longevity of the ice making system:
• IMPORTANT: Excess tubing shall be coiled inside the building in a
vertical spiral as shown below.
• All tubing routed outdoors shall be insulated to protect against external
ambient conditions.
• Tubing should follow straight line routing whenever possible.
• The lowest location in the tubing run should be the connection at the
rear of the ice maker.
Make Roof/Wall Openings for Tubing
Make openings in walls and/or roof as needed to route refrigerant tubing
through. Hole size shall be minimum 1.75 inch [44.5 mm] diameter.
Route Refrigerant Tubing
WARNING
Pre-charged Line Sets Under Pressure
Wear eye protection when handling pre-charged line sets.
Failure to do so can result in eye or other injury.
Each set of pre-charged refrigerant line sets consists of a 3/8 inch
diameter liquid line and a 1/2 inch diameter discharge line. Both ends
of the refrigerant lines have quick connect couplings and Schrader valve
service connections.
WARNING: When handling pre-charged refrigerant line sets, extreme
care should be taken to ensure tubing is not kinked or cracked. Kinked
tubing can result in a poorly performing ice making system. A cracked
tube will require repair by a qualied refrigeration technician.
Route Refrigerant Tubing
• Route refrigerant tubing as planned, following guidelines above
• Have a qualied technician seal holes in walls/roof following all
applicable building codes
Note: Do not connect the pre-charged tubing until all routing and forming
of the tubing is complete. Failure to do so may result in equipment
damage.
Make Refrigerant Tubing Connections to Remote
Condenser and Ice Maker
The couplings supplied with pre-charged line sets are self-sealing
when installed properly. To ensure a leak-free installation, follow these
instructions carefully.
• Preparation: Remove caps and plugs from the couplings when ready
to connect. Check the threads and seals for damage. Wipe away any
foreign material from the coupling threads and sealing surfaces with a
clean cloth.
• Lubricate: Apply POE (polyol ester) refrigerant oil to the surfaces of
the diaphragms, o-rings, and threaded areas of the couplings. Failure
to apply lubricant can result in damage and leaks. POE oil is included
with line sets and line set kits. Use a small applicator brush and
liberally apply lubricant.
• Hand Tighten: Ensure that the coupling halves are held in proper
alignment with each other prior to starting the threads. The coupling
end faces should be parallel with each other and visually in-line.
Tighten by hand for the initial 2-3 rotations of the swivel nut. If it is too
dicult to get started by hand, repositions the nut for proper alignment.
Do not force the connection as cross-threading may occur.
• Wrench Tighten: Using two appropriate sized wrenches (see table
below), tighten the swivel nut while preventing rotation of the coupling
body. As the swivel nut is tightened, the diaphragms will start to be
pierced and there will be an increase in resistance. Important: Do not
let the coupling bodies rotate during any portion of the installation or
damage will occur. Continue to tighten the swivel nut until there is a
denite increase in resistance and metal-to-metal contact occurs. At
this point, the swivel nut will have covered most of the threads.
• Final Tighten: A nal 1/4 turn (90° rotation) is necessary to ensure
the formation of a leak-free sealed connection between the couplings.
Using a marker or scribe, mark a line lengthwise from the coupling
swivel nut to either the bulkhead or coupling body. Then tighten an
additional 1/4 turn (90° rotation), using the marking on the swivel nut to
conrm. Do not over tighten.
• Leak Check: Once all connections have been made, check each
connection for leaks.

SERVICE
WARNING
Electrical Shock Hazard
Disconnect electrical supply from machine prior to performing
any adjustments or repairs.
Failure to do so can result in death, re, or electrical shock.
IMPORTANT: For proper and safe servicing, please read these
instructions completely. All service work must be performed by authorized
service personnel.
See the following Remote Condenser Refrigeration System Diagram and
the component descriptions.
Head Pressure Control Valve: The head pressure control valve (also
known as the Headmaster, Mixing Valve, or Low Ambient Control Valve)
serves as the head pressure regulating valve. When the temperature
of the condenser is above 70 °F [21 °C], the refrigerant ow from the
compressor is directed by the mixing valve through the condenser and
into the receiver. When the temperature at the condenser drops below
70 °F [21 °C], the pressure in the bellows of the mixing valve becomes
greater than the pressure of the liquid refrigerant in the condenser. This
change allows the valve to partially restrict the ow of refrigerant leaving
the condenser and allows discharge gas to bypass the condenser and
ow directly into the receiver, mixing with the liquid refrigerant from the
condenser. The amount of discharge gas that bypasses the condenser
increases as the ambient temperature decreases. This action of the
mixing valve allows the discharge pressure to be properly maintained
during low ambient conditions: for cube ice makers, discharge pressure is
maintained at approximately 210-240 psig [1.45-1.66 MPa]; for nugget/
flake ice makers, 170-200 psig [1.17-1.38 MPa]. If the refrigerant system
is undercharged and the ambient temperature is below 70 °F [21 °C], the
mixing valve will not work properly and allow too much refrigerant to
bypass the condenser.
Receiver: Stores liquid refrigerant discharged from the condenser. The
quantity of liquid refrigerant in the receiver will vary with the temperature
at the condenser coil.
Liquid Line Solenoid: Controls the flow of liquid refrigerant from the
receiver to the thermal expansion valve (TXV).
Pump Down Control: Low-pressure switch that has a opening pressure
of approximately 5-10 psig [34.4-68.9 kPa] that controls the contactor to
shut the compressor off during pumpdown. The low-pressure switch
resets (contacts close) when the low side pressure rises to approximately
25-35 psig [172.4-241.3 kPa].
Condenser Fan Motor: The condenser fan motor is a single speed and
should be wired according to the wiring diagram. The motor is
permanently lubricated for long-life.
DISPOSAL
IMPORTANT: This appliance contains refrigerant and must be disposed
of in accordance with applicable national, state, and local codes and
regulations. Refrigerant must be recovered by properly certified service
personnel.
