Eclipse 800 System: CME810, CP886, ERC680*
Eclipse 1000 System: CME810, CP1086,
ERC1086*
*ERC680 or ERC1086 may be substituted for by
an approved central condenser coil & fan (coil
must be without headmaster - headmaster is part
of CP680 or CP1086).
Note: The ice making section cannot be stacked

Special Considerations
The ice making section’s footprint is 22” wide by
16.5” 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 at any position
left to right; it may also be routed to either side.
The ice sensors, used for determining if the bin is
full or not, are located in housings that extend
below the bottom of the unit. As ice is made, it will
build up in the bin or dispenser until the top of the
ice pile is between the sensors. At that point, about
3” below the bottom of the cabinet, the ice machine
will shut off. 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 discharge 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 50
microns) or coiled up inside the building.
Installations with greater than 20 feet of vertical lift
between ice machine and the compressor 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.
Confirm Component Availability:

·
CP686 or CP886 or CP1086
·
ERC680 or ERC1086 or ER2C6810 unless
·
connecting to an approved condenser coil.
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 unique footprint of the CME686 and CME810
require adapter kits to allow placement on
dispensers and bins. The remote tubing
connections must be made from the right side of
the machine, and connections should not be made
until the machine is nearly in its final installed
position. The 115/60 Hz ice making section is cord
connected and requires an outlet within 6 feet of
the installation.

Eclipseä 600, 800, 1000
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.

Route Tubing
Eclipseä 600, 800, 1000
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 out the top, use the
·
double-bend ends.
Liquid
Vapor
Suction
If the tubing is to be routed out the back, use
·
the ends with the single 90 degree bends.
Liquid
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
Suction
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 a 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.
