3. Line Set Installation
WARNING
• R-404A itself is not ammable at atmospheric pressure and temperatures up to
176°F (80°C).
• R-404A itself is not explosive or poisonous. However, when exposed to high
temperatures (open ames), R-404A can be decomposed to form hydrouoric
acid and carbonyl uoride both of which are hazardous.
• Do not use silver alloy or copper alloy containing arsenic.
• Do not open any service valve until the line set installation is complete and leak
tested.
• Ensure that there are no unnecessary traps and no kinks in the line set.
• Do not coil extra line set.
• Use an electronic leak detector or soap bubbles to check for leaks. Add a trace of
refrigerant to the line set tubing through the service valve access ports (ifusing
an electronic leak detector), and then raise the pressure using nitrogen gas
(140PSIG). Do not use R-404A as a mixture with pressurized air for leak testing.
1) Route the factory line set or appropriate size copper tubing. When eld fabricating,
insulate the copper tubes separately. Leave a service loop behind the icemaker to
allow the icemaker to be pulled out for service. See Fig. 9. Note: The service loop is not
considered an oil trap.
2) Remove any extra line set length.
3) NOTICE! Before brazing, remove the Schrader valve cores from the service valve
access ports. When brazing, protect the service valve by using a wet cloth to
prevent the service valve from overheating.
4) Braze the line set to the icemaker service valves rst, then to the remote condensing
unit service valves.
5) Allow the service valves to cool, then replace the Schrader valve cores.
6) Use an electronic leak detector or soap bubbles to check for leaks. Add a trace of
refrigerant to the line set tubing through the service valve access ports (if using an
electronic leak detector), and then raise the pressure using nitrogen gas (140 PSIG).
WARNING! Do not use R-404A as a mixture with pressurized air for leak testing.
7) Attach the gauge manifold hoses to the service valve access ports and evacuate the
line set tubing. Allow the vacuum pump to pull down to a 29.9" Hg vacuum. Evacuating
period depends on pump capacity. Next, charge each line set tube with R-404A vapor
to a pressure of 15 to 30 PSIG.
8) Close both gauge manifold valves.
9) Disconnect the gauge manifold hoses.
10) Replace the service valve access port caps and tighten.
11) Open the icemaker service valves rst, then open the remote condensing unit service

WARNING
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. If fabricating a wire bundle, use wire of an
appropriate gage and outdoor rating. 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.
• To reduce the risk of electric shock, do not connect the remote condensing unit
power supply until after all wire bundle connections have been made.
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.
• Remote condensing unit electrical connection must be made in accordance with
the instructions on the "WARNING" tag provided with the pig tail leads in the
remote condensing unit's power supply junction box. See Fig. 10.
NOTICE
The remote condensing unit must have power for a minimum of 4 hours prior to
startup to prevent compressor damage.
• Usually an electrical permit and services of a licensed electrician are required.
• The maximum allowable voltage variation is ±10 percent of the nameplate rating.
• The openings for the power supply and wire bundle connections are 7/8" DIA to t a
1/2" trade size conduit.

1) Route the wire bundle between the icemaker and remote condensing unit. Use the wire
bundle supplied with the remote condensing unit, or fabricate a wire bundle using wire
of an appropriate gage and outdoor rating. Use the wiring label or Fig. 11 as a reference.
2a) Icemaker: Connect the wire bundle ground wire to the icemaker ground screw, then
connect the rest of the wire bundle wires to the icemaker terminal block.
WARNING! Do not connect the wire bundle ground wire to the icemaker terminal
block.
2b) Remote Condensing Unit: Connect the wire bundle ground wire to the remote
condensing unit ground screw (located next to the terminal block).
WARNING! Do not connect the wire bundle ground wire to the remote
condensing unit terminal block.
3) Connect the power supply from the disconnect or electrical panel to the leads in
the remote condensing unit's power supply junction box. This differs from KM style
installations. Connect a ground wire to the ground screw. See Fig. 11.
• The white lead must be connected to the neutral conductor of the power source.
NOTICE! Miswiring may result in severe damage to the icemaker.
4) Replace all removed parts and panels in their correct positions.
5) Turn on the power supply to the remote condensing unit. NOTICE! The remote
condensing unit must have power for a minimum of 4hours prior to startup to
prevent compressor damage.
