of the front of the ice machine. Refer to below for clearance requirements.
Ice Machine Head Section ClearanceRequirements

Ice Machine Heat of Rejection
Ice machines, like other refrigeration equipment, reject heat through the condenser. It is helpful to know the
amount of heat rejected by the ice machine when sizing the air conditioning equipment where self-contained aircooled
ice machines are installed. QF2300 ice machines add an insignificant amount of load to a conditioned space.
Location of Remote Condensing Unit
The location selected for the Remote Condensing Unit must meet the following criteria. If any of these criteria
are not met, select another location.
• The air temperature must be at least -20°F (-28.9°C) but must not exceed 120°F (49°C).
• The location must not allow exhaust fan heat and/or grease to enter the condenser.
• The location must not obstruct airflow through or around the condensing unit. Refer to the chart below
for clearance requirements.
CONDENSING UNIT CLEARANCE REQUIREMENTS

The ice machine head section must be protected if it will be subjected to temperatures below 32°F (0°C).
Failure caused by exposure to freezing temperatures is not covered by the warranty. See
“Removal from Service/Winterization”.

Electrical Service
VOLTAGE
The maximum allowable voltage variation is ±10% of the rated voltage on the ice machine model/serial number
plate at start-up (when the electrical load is highest).
GROUND FAULT INTERRUPTER CIRCUIT (GFIC)
Ground Fault Circuit Interrupter protection is a system that shuts down the electric circuit (opens it) when it
senses an unexpected loss of power, presumably to ground. Manitowoc Ice, Inc. does not recommend the
use of a GFCI/GFI circuit protection with our equipment. If code requires the use of a GFCI/GFI then you must
follow the local code. The circuit must be dedicated (accept QuietQubes), sized properly and there must be
a panel GFCI/GFI breaker. We do not recommend GFCI/GFI outlets as they are known for more intermittent
nuisance trips than panel breakers.
FUSE/CIRCUIT BREAKER
A separate fuse/circuit breaker must be provided for each ice machine. Circuit breakers must be H.A.C.R.
rated (does not apply in Canada). QF400 115/60/1 ice machines are factory pre-wired
with a power cord and 5-15P plug confirmation. QF400 230/50/1 ice machines are factory pre-wired
with a power cord, no plug is supplied. QF2300 with Remote Condensing Unit the ice
machine head section and remote condensing unit are wired independent of each other. A separate dedicated
fuse/circuit breaker must be provided for each section.Circuit breakers must be H.A.C.R. rated (does not apply
in Canada).
TOTAL CIRCUIT AMPACITY
QF400 Only
The total circuit ampacity is used to help select the wire size of the electrical supply.
The wire size (or gauge) is also dependent upon location, materials used, length of run, etc., so it must be
determined by a qualified electrician.
MINIMUM CIRCUIT AMPACITY
QC700/QF800/QF2300 Only
The minimum circuit ampacity is used to help select the wire size of the electrical supply. (Minimum circuit
ampacity is not the ice machine’s running amp load.) The wire size (or gauge) is also dependent upon
location, materials used, length of run, etc., so it must be determined by a qualified electrician.

All wiring must conform to local, state and nationalcodes.

The ice machine must be grounded in accordance with national and local electrical codes.

Water Supply and Drains
POTABLE WATER SUPPLY
Local water conditions may require treatment of the water to inhibit scale formation, filter sediment, and
remove chlorine odor and taste.
POTABLE WATER INLET LINES
Follow these guidelines to install water inlet lines:
• Do not connect the ice machine to a hot water supply. Be sure all hot water restrictors installed for
other equipment are working. (Check valves on sink faucets, dishwashers, etc.)
• If water pressure exceeds the maximum (80 psig 551.5 kPA) recommended pressure, obtain a water
pressure regulator from your Manitowoc distributor.
• Install a water shut-off valve and union for both the ice making and condenser water lines.
• Insulate water inlet lines to prevent condensation.
DRAIN CONNECTIONS
Follow these guidelines when installing drain lines to prevent drain water from flowing back into the ice
machine and storage bin:
• Drain lines must have a 1.5 inch drop per 5 feet of run (2.5 cm per meter), and must not create traps.
• The floor drain must be large enough to accommodate drainage from all drains.
• Run separate bin and water-cooled condenser drain lines. Insulate them to prevent condensation.
• Vent the bin and ice machine drain to the atmosphere. The ice machine drain requires an 18”
vent. Do not vent the condenser drain on watercooled models.
• Drains must have a union or other suitable means to allow in place disconnection from the ice machine
when servicing is required.
Cooling Tower Applications
(Water-Cooled Models)
A water cooling tower installation does not require modification of the ice machine. The water regulator
valve for the condenser continues to control the refrigeration discharge pressure.
It is necessary to know the amount of heat rejection, and the pressure drop through the condenser and water
valves (inlet and outlet) when using a cooling tower on an ice machine.
• Water entering the condenser must not exceed 90°F (32.2°C).
• Water flow through the condenser must not exceed 5 gallons (19 liters) per minute.
• Allow for a pressure drop of 7 psi (48 kPA) between the condenser water inlet and the outlet of the ice machine.
• Water exiting the condenser must no exceed 110°F (43.3°C).
Important
If you are installing a Manitowoc water filter system, refer to the Installation Instructions supplied with the
filter system for ice making water inlet connections.
Important
The Commonwealth of Massachusetts requires that all water-cooled models must be connected only to
a closed loop, cooling tower system.

(QF2300/RFC2385 ONLY)
USAGE WITH NON-MANITOWOC
CONDENSING UNITS
Manitowoc Condensing Units are specifically designed for usage with a Manitowoc Flake/Chiplet Ice Machine
Head Sections. Manitowoc Flake/Chiplet Ice Machines will not operate with non-Manitowoc condensing units.
Factory Equipment Refrigeration Amounts
ICE MACHINE HEAD SECTION
Each ice machine head section ships from the factory with a R-404A refrigerant charge appropriate for line
sets up to 50’ in length (12.5 lbs.). The serial tag on the ice machine indicates the refrigerant charge. Additional
refrigerant must be added for line set lengths between 50’ and 100’ (1.5 lbs.) see chart below.
REMOTE CONDENSING UNIT
Each condensing unit ships from the factory pressurized with 50/50 nitrogen helium mixture that must be
removed during the installation process (approximately 20 psig).
REFRIGERATION LINE SETS/TRAPS KIT
Refrigeration Rated Tubing and Trap Kits are shipped capped with atmospheric pressure.

Installation of a Remote Condensing Unit may require the use of special equipment for placement. Trained and
qualified personnel are required for proper rigging and lifting.

The 60-month compressor warranty (including the 24-month labor replacement warranty) will not apply if
the Manitowoc Ice Machine and remote Manitowoc Condensing Unit are not installed according to
specifications. This warranty also will not apply if the refrigeration system is modified with a condenser,
heat reclaim device, or other parts or assemblies not manufactured by Manitowoc Ice, Inc.
Series Charge QF2200/QF2300 RFC2085/ RFC2385
0’ to 50’ linesets 12.5 lbs (5.7 kg)
50’ to 100’ linesets 14.0 lbs (6.4 kg)

Never add more than nameplate charge to the refrigeration system for any application.

Potential Personal Injury Situation
The ice machine head section contains the refrigerant charge. Installation and brazing of the line sets must be
performed by a properly trained and EPA certified refrigeration technician aware of the dangers of dealing
with refrigerant charged equipment.

Refrigeration Line Set Installation
GENERAL
Refrigeration line set installations consist of vertical and horizontal line set distances between the ice machine
and the condensing unit. The following guidelines, drawings and calculation methods must be followed to
assure proper oil return and condensing unit/ice machine operation.
The refrigeration line set installer must be USA Government-Environmental Protection Agency (EPA)
certified in proper refrigerant handling and servicing procedures.
Step 1 Verify Ice Machine and Remote Condensing Unit Locations Are Within Guidelines.
Prior to installation of the ice machine and remote condensing unit be sure that the distance between then
is within the line set routing guidelines outlined in this manual.
Roof/Wall Penetration
If required, cut a 3-inch (76.2 mm) circular hole in the wall or roof for routing of refrigeration tubing. A qualified
person must perform all roof penetrations.
Step 2 Route Refrigeration Tubing
Properly route refrigeration tubing between the ice machine head section and the remote condensing unit.
A. LINE SET LENGTH
100 feet (30.5 m) Length: The maximum measured length the line set can be. The receiver is designed to hold a
charge sufficient to operate the ice machine in ambient temperatures between -20°F (-28.9°C) and 120°F (49°C),
with line setlengths of up to 100 feet (30.5 m).
B. LINE SET RISE OR DROP
35 feet (10.7 m) Rise: The maximum distance the remote condensing unit can be above the ice machine.
15 feet (4.5 m) Drop: The maximum distance the remote condensing unit can be below the ice machine.

Disconnect electrical power to the ice machine head section and the remote condensing unit before proceeding.

The ice machine head section contains refrigerant charge. The ice machine head section contains three
(3) refrigeration valves that must remain closed until proper installation of the line set is completed.
Important
The ice machines will not function with line sets greater than 100 feet (30.5 m). Do not attempt to go
beyond this distance and add refrigerant charge to compensate!

C. SUCTION LINE OIL TRAPS
0 to 20 feet (0 to 6.1 m) Rise: The ice machine head section has one oil trap built in which allows for a
maximum condenser rise of 20 feet (6.1 m) without additional traps in the suction line.
21 to 35 feet (6.4 to 10.7 m) Rise: The suction line requires an additional Oil Trap (“S” type) to be installed.
Install the trap as close as possible to midpoint between the ice machine head section and remote condensing
unit. S-Trap Kits are available from Manitowoc (refer to chart).
Manitowoc S-Trap Kit
Service Loop
A service loop in the line set permits easy access to the ice machine for cleaning and service.
• The supplied service loop is an installation requirement.
• A service loop is not considered an oil trap.
• The service loop is not included when calculating length, rise or drop of the tubing run.
• Do not use hard rigid copper for the service loop.
Step 3 Lengthening or Reducing Line Set Lengths
When the line set required shortening or lengthening, do so before connecting the line set to the ice machine
head section or the remote condensing unit. Do not form unwanted traps in refrigeration lines.
Never coil excess refrigeration tubing.
Model S-Trap Kit Number Tubing Size QF2300 K00166

If a line set has a rise followed by a drop, another rise cannot be made. Likewise, if a line set has a drop
followed by a rise, another drop cannot be made. Do not form unwanted traps in refrigeration lines.
Never coil excess refrigeration tubing.

Step 4 Connecting the line set.
To prevent oxidation of the copper, purge line set and condensing unit with dry nitrogen while brazing.
Connect The Line Set To The Ice Machine Head Section
The line set shut off valves at the back of the ice machine must remain closed and be protected from heat
during the brazing process. Wrap the valves in a wet rag or other type of heat sink prior to brazing. Cool braze
joint with water immediately after brazing to prevent heat migration to the valve.
Connect The Line Set To The Remote Condensing Unit
The compressor oil rapidly absorbs moisture. Be prepared to complete line set installation and start your
evacuation process in order to minimize the time the compressor is exposed to the atmosphere. (Maximum
amount of time the system can be exposed to the atmosphere is 15 minutes).
The line set can be routed for entry through the front or left side of the condensing unit.
• Remove knockout for preferred location.
• Insert supplied plastic bushings in knockout holes to prevent tubing from contacting sheet metal.
• Use the supplied 90° elbows to route tubing.
• Cut the tubing ends of the suction and liquid lines and braze the line sets to the condensing unit.

The ice machine head section contains refrigerant charge. The ice machine head section contains three
(3) refrigeration valves that must remain closed until proper installation of the line sets is completed.

The condensing unit ships from the factory pressurized with a 50/50 mixture of nitrogen/helium.
Bleed off pressure from both suction and liquid line access ports prior to cutting into refrigeration lines.
VALVES MUST REMAIN CLOSED AND BE PROTECTED FROM HEAT WHEN BRAZING
(WRAP WITH WET RAG)

MINIMIZE THE TIME THE REFRIGERATION SYSTEM IS EXPOSED TO THE ATMOSPHERE
(15 MINUTES MAXIMUM)

Step 5 Pressure Test and Evacuate The Line Set and Remote Condensing Unit
Schrader valve core removal tools that allow for removal and installation of the valve cores without removing
manifold gauge set hoses are recommended to decrease the evacuation time.
Leave the line set shut off valves closed (front seated). Pressure test the line sets and remote condensing unit
with 150 psig of dry nitrogen. Add nitrogen at the line set shut off valves located at the back of the ice machine.
Complete the pressure test, verify no leaks are present and remove the nitrogen from the system before
connecting the vacuum pump. Connect a vacuum pump to both of the line set shut off valves located at the back
of the ice machine head section. Evacuate to 250 microns (or less). To completely evacuate the Remote
condensing unit, continue the evacuation for 30 minutes after reaching the 500 micron point.
If required, the line set and condensing unit can be evacuated from the schrader valves located in the
remote condensing unit. Schrader valve core removal tools (that allow for putting the cores back in without
removing vacuum pump hoses) must be used if evacuating from the condensing unit side.
Isolate the vacuum pump from the line set shut off valves and/or condensing unit access ports prior to
proceeding. Open refrigeration system shut off valves. The suction line, liquid line and receiver service valves
are closed during shipment and installation.
Step 6 Open The Valves Prior To Starting The Ice Machine.
A. Slowly backseat (open-turn counterclockwise) the suction line shut off valve.
B. Slowly backseat (open-turn counterclockwise) the liquid line shut off valve.
C. Slowly backseat (open-turn counterclockwise) the receiver service valve.
NOTE: You will not hear refrigerant flow when the valves are opened. Refrigerant will not flow until the toggle
switch is placed in the ice position and the liquid line solenoid valve opens.
OPEN SUCTION AND LIQUID LINE SHUT OFF VALVES
Verify O-ring in schrader valve caps are intact and reinstall on shut off valves to prevent refrigerant leakage.
Replace shut off valve access caps and torque to the following specifications.
Torque Value’s CONNECT VACUUM PUMP TO LINE SET SHUT OFF VALVES SV1757
ALTERNATE CONNECTIONS AT CONDENSING UNIT SCHRADER VALVES SV2085
! Caution
After opening suction, discharge and receiver service valves, refrigerant pressure will not be detected until
the toggle switch is placed in the ICE position and the liquid line solenoid valve energizes.

USE ALLEN WRENCH TO OPEN (TURN COUNTERCLOCKWISE) LIQUID AND SUCTION LINE
SHUT-OFF VALVES

Replace cap on receiver service valve and tighten.
Open Receiver Service Valve
There is a liquid line solenoid valve at the outlet of the receiver; refrigerant will not flow to the condensing unit
until the ice machine head section is started. Connect power to both the ice machine head section and the
Remote condensing unit. Place the ICE/OFF/CLEAN toggle switch into the ICE position, this will allow
refrigerant to enter the line set and condensing unit. Step 7 Leak Check The Refrigeration System
Leak check the new line set connections at the ice machine head section, condensing unit and S trap as
well as all factory joints throughout the entire system. Disconnect power to the remote condensing unit. Place
the ICE/OFF/CLEAN toggle switch into the ICE position. This allows the low side and high side pressures to
equalize. Place the ICE/OFF/CLEAN toggle switch in the OFF position. Connect power to the remote condensing
unit and allow system to pump down.
Step 8 Insulation Requirements
To prevent condensation the entire suction line including the shut-off valve must be insulated. All insulation must
be airtight and sealed at both ends. The following insulation requirements prevent
condensation at 90°F (32.2°C) ambient 70% Relative Humidity. If higher humidity is expected, increase
insulation thickness. The entire line set, including the suction service valve located on the back of the ice machine requires:
Important
All refrigeration valve caps must be reinstalled to prevent future refrigeration leaks.
TURN COUNTERCLOCKWISE SV1756 RECEIVER SERVICE VALVE CAP (TURN COUNTERCLOCKWISE
TO REMOVE)

Important
To prevent condensation the entire suction line including the shut off valve must be insulated. All
insulation must be airtight and sealed at both ends. The minimum requirements are for conditions at or
below 70% humidity and 90°F (32.2°C) ambient. When higher humidity will be experienced, insulation
wall thickness will need to be increased.

Suction Shut Off Valve Insulation
The pre-formed suction shut-off valve insulation is located in the plastic bag taped to the water curtain.
A. Verify valve and schrader caps are tightened to specifications (see Step 6).
B. Place insulation over schrader valve cap and left side of valve. Position the tab between the
mounting bracket and rear panel.
C. Fold insulation and hold against right hand side of valve while securing with electrical tape. Seal
the line set insulation to the shut off valve insulation with electrical tape.
