CME2086, CP2086, ERC2086
·
*ERC2086 may be substituted for by an approved central condenser coil & fan (coil must be without headmaster - headmaster is part of CP2086).
Note: The ice making section cannot be stacked vertically.
Accessories such as bin adapters and tubing kits are required to complete the installation.

Special Considerations
The ice making section’s footprint is 30” wide by 24” deep. The refrigeration connections can be made out the top panel or out the back. The electrical power cord and the water inlet line can also be routed through either of those areas. The drain may be routed out the back or to the left side.
The bin thermostat, when deployed, will be about 5” below the bottom of the cabinet, and that is where the ice will fill to. This ice level maximizes ice storage without overfilling the bin or dispenser.
Water
Pure water does not exist. All water supplies contain some amounts of impurities, although potable water is, by definition, fit for human consumption. Because the contents of the water to an ice machine directly impact its performance, consideration should be given to improving the water’s quality.
There are two ways water can contain impurities: in suspension or in solution. Suspended solids can be filtered out of the water. In solution or dissolved solids must be diluted or treated. Water filters are recommended to remove the suspended solids. Some filters or filter systems have treatment chemicals in them for treating the suspended solids.
This ice machine has an adjustment for the amount of water rinsed or purged. Water use adjustments are customer convenience adjustments; they are not factory defects and are not covered by warranty.

Create the System
Plan the installation. The system consists of four parts: the ice making section, the compressor package, the interconnecting tubing and the remote condenser. Of these, the biggest variable is the interconnecting tubing.
Tubing: The tubing consists of three pre-charged, insulated and sealed soft copper tubes. They each contain a small holding charge of R-404A. One tube, the liquid line, is 3/8” OD. The vapor tube is ½” OD and the suction tube is ¾” OD. A site inspection will determine what length of tubing is required for the installation.
Excess tubing must be either shortened at the job site (recovering the holding charge, purging with nitrogen when brazing and evacuating to 200 microns) or coiled up inside the building.
Installations where the ice making head is more than 20 feet below the compressor package require a suction line trap. The suction line requires careful handling and large radius bends to prevent kinking.
Roof mounting: To make installation easier the compressor and condenser are designed to be assembled together on the roof. Some installations will require the use of a hoist to lift the components to the roof.
Pad mounting: The compressor and condenser may be located below the ice making section, up to a limit of 15 feet.
Distance from unit: Limited to the length of the available pre-charged tubing.
Interconnecting wires: An interconnecting wire harness is included with the CP unit. One end plugs into the ice making section and the other into the compressor package. The system will NOT operate without this harness.
Exposed tubing: Minimize the amount of tubing exposed outdoors.

Note: Only these condensers may be used. They do NOT contain a headmaster valve. That valve is in the Compressor Package. Do NOT use any other Scotsman condenser. Do NOT use these condensers on any other Scotsman remote product.
Interconnecting tubing kit
·
Note: Check tubing integrity before assembly by attaching a refrigeration compound gauge onto one of each tube’s schrader valves. If there is pressure, the tube is OK, if not it should be checked for damage and leaks.
·
Bin or dispenser adapter
Elevation: CP unit limited to 35 feet above the ice making section.
Compressor package: Electrical power must be supplied to the compressor package. The remote condenser fan motor takes its power from the compressor package.
Ice making section location and attachment:
The 115/60 Hz ice making section is cord connected and requires an outlet within 6 feet of the installation.

System Examples
A variation of the typical system set up is one that uses a non-Scotsman condenser. In that case the CP unit is NOT bolted to the condenser and a RTE10 line set is used to connect the CP’s refrigeration system to the condenser’s.

Place Remote System
Eclipseä 2000
Roof preparation
Most installations of this system will place the compressor package and condenser on the roof of a building. The roof must be physically stout enough to accept the load of the equipment and the roofing material must be prepared to prevent water leaks.
Follow local codes for the placement and attachment of the equipment.
Location
The condensing unit assembly requires unobstructed air flow to operate efficiently. A four foot space between each intake side and a wall or other cabinet is recommended.
Do not place where it will pick up hot discharged air from an air conditioner or other refrigeration system condensing unit.
Space must also be reserved for service on the compressor package. If using the ER2C6810 condenser, save space for the second CP unit to be attached to the other end of the condenser.
Roof Piercing:
The roof (or wall) must have a passage large enough for the three pre-charged, pre-bent tubes and the control wire to pass through. The minimum recommended size is 4” ID. In most areas the power supply may also pass through the same passage. If there isn’t a passage one must be created. In most cases this must be done by a licensed and bonded roofer in order to maintain the roof’s integrity.
Suggestions:
Hoist the compressor package and condenser to the roof in separate loads.
Note: In most cases a mechanical lift, boom truck or crane will be required to hoist the condensing unit components.
Assemble the compressor package to the condenser and mount both to either roof rails or pressure treated4x4s.
Orient the assembled unit so that the unit’s mounts are parallel to the pitch of the roof to allow water to drain freely.

Do NOT place the unit directly onto roof rock.

Route Tubing
Eclipseä 2000
Scotsman’s pre-charged tubing kits are pre-bent to fit the connection path at the ice making section.
If the tubing is to be routed straight out the
·
back, use the double-bend ends.
Suction
Vapor
Liquid
If the tubing is to be routed out the back and
·
then up, use the ends with the single 90 degree bends.
Suction
Select the correct end to send to the roof.
The method or technique used to route the tube is left to the installer. However, in many cases it is easier to position the tubing inside the building first, then feed the outside portion through the tubing passage (pitch pot). Installation of tubing will be easier if the suction line is run first, followed by the liquid and vapor lines. Use of two persons is suggested to prevent kinking of the tubing, long runs may require three people.
Allow enough tubing to make large radius bends
·
from the roof passage to the compressor unit. Do NOT leave excess tubing on the roof.
If a trap must be installed, the suction line
·
tubing must be cut apart to install it.
Identify the ice machine end of the tubing. Each
·
tube has one end formed to route through the hole in the unit’s top.
Tape the ends of the vapor and liquid line tubes
·
together along with the interconnecting wire. Extend the end of the interconnecting wire about 2 feet beyond the end of the precharged tubes and then tape it back onto the tubes.
·
Route the three tubes and the wire from the roof, or other entrance, to the ice making section’s planned position. Avoid uncoiling and recoiling the tubing, as that can lead to kinks.
Vapor
Liquid
Note: Units mounted flush against the wall require refrigerant connections out the top, water supply in from the top, power supply routed through the top and drain routed to the left side.
·
Support long runs of tubing with hangers.
·
Repair any tears in the tubing insulation, especially those on the suction line that are inside the building.
Shortening Tubing
The precharged tubing kits are available in a variety of lengths, they should only be shortened if absolutely necessary.
To Shorten Tubes:
1. Recover the 3 ounce R-404A holding charge from each tube.
2. Cut out the required length of tubing, do not cut the tubing right at the quick connects.
3. Attach nitrogen bottle to one quick connect and a hose with a depressor to the other end, purge nitrogen through each tube while brazing.
4. Remove nitrogen, evacuate to 200 microns.
Note: If tubes are connected to the IMS, evacuate the vapor & suction lines to get the entire system.
