FOR THE INSTALLER: Remote Condenser (Scotsman)
Pre-charged Line Routing
/////////////////////////////CAUTION///////////////////////////////
Do not connect pre-charged 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, one end has flexible
tubing: that end 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 (as
illustrated) to avoid any traps in the lines.
5. Have the roofing contractor seal the holes in the
roof per local codes.
6. The flexible line end must be installed behind
the icemaker, it is to be looped down from the ice
machine connection area then back up to the wall
behind the ice machine. This allows the ice
machine to be pulled out for service.
