For The Installer: Remote Condenser
Locate the condenser as near as possible to the
interior location of the ice maker.
Note: The location of the condenser relative to the
ice machine is LIMITED by the specification on the
following page.
Select the best available location, one that protects
the condenser from excessive dust, grease & sun.
Meet all applicable building codes.
Roof Attachment
Install and attach the remote condenser to the roof
of the building, using the methods and practices of
construction that conform to the local building
codes, including having a roofing contractor secure
the condenser to the roof.
Note: If using any other condenser besides the
ERC111 or ERC211, its use must be approved by
Scotsman, and a head pressure control valve must
be connected to the condenser coil.
Line Routing
Do not connect the tubing until all routing
and forming of the tubing is complete.
See the Coupling Instructions for final
connections.
If two CME456R ice machines are to be
installed, mark one as Ice Machine #1
and the other as Ice Machine #2. Tag
their refrigerant lines the same way.
1. Each set of pre-charged tubing lines
contains a
" diameter liquid line, and a
3
8
" diameter discharge line. Both ends of
1
2
each line have quick connect couplings,
the end without access valves goes to
the ice maker.
Note: The openings in the building ceiling
or wall, listed in the next step, are the
minimum sizes recommended for
passing the refrigerant lines through.
2. Have the roofing contractor cut a
minimum hole for the refrigerant lines of
2". Check local codes, a separate hole
may be required for the electrical power
supply to the condenser.
Caution: Do NOT kink the refrigerant
tubing while routing it.
3. Route the refrigerant tubes thru the roof
opening. Follow straight line routing whenever
possible.
If connecting two ice machines, be sure that the
tubes from ice machine #1 are connected to one
circuit of the condenser and the tubes from ice
machine #2 are connected to the other.
Note: Excess tubing may EITHER be coiled up
INSIDE the building OR cut out prior to connection
to the ice maker and condenser.
If the excess tubing is cut out, after re-brazing the
tubing must be evacuated prior to connection to
the ice maker or condenser.
If the excess tubing is to be coiled, spiral it
horizontally to avoid excess trapping in the lines.
Note: A 36" service loop may be placed behind the
ice machine.
5. Have the roofing contractor seal the holes in the
roof per local codes.
