FOR THE INSTALLER: Scotsman Remote Condenser
Locate the condenser as near as possible to
the interior location of the ice maker.
Location of the condenser is limited by the specific
length of precharged refrigerant tubing supplied for
the application. The pre-charged tubing connects
the icemaker to the remote condenser. The
condenser must be above the ice maker.
Select the best available location, protecting the
condenser from extremes of dirt, dust, and sun.
Meet all applicable building codes.
Roof Attachment:
Install and attach the remote condenser unit 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.

Precharged Line Routing
/////////////////////////////CAUTION///////////////////////////////
Do not connect precharged tubing until all routing
and forming of the tubing is complete. See the
coupling instructions for connecting instructions.
////////////////////////////////////////////////////////////////////////////
1. Each set of precharged refrigerant lines consists
of a 3/8 inch diameter liquid line, and a 1/2 inch
diameter discharge line. Both ends of each line
have quick connect couplings, the end without
access valves goes to the icemaker.
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 1.75". Check local
codes, a separate hole may be required for the
electrical power to the condenser.
/////////////////////////////CAUTION////////////////////////////////
DO NOT KINK OR CRIMP REFRIGERANT
TUBING WHEN INSTALLING IT.
////////////////////////////////////////////////////////////////////////////
3. Route the refrigerant lines through the roof
opening.
Follow straight line routing whenever possible.
Any excess tubing MUST be retained within the
building.

4. Spiral any excess length of
pre charged tubing inside the
building. Use a horizontal spiral
to avoid any traps in the lines.
5. Have the roofing contractor
seal the holes in the roof per
local codes.
6. The flexible end of the tubing
must be installed behind the
icemaker; it is to be looped
down from the ice machine
connection area then back up
the wall behind the ice machine.
This allows un-stacked units to
be pulled out for service.
