Route Tubing
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 up, use the
straight ends.
Vapor
·
If the tubing is to be routed to the back, use
the ends with the single 90 degree bends.
Liquid
Vapor
Suction
Note: Water inlet, power, interconnecting control
wire and refrigerant connections are located at the
back of the top panel. Drain may be routed back,
left or right.

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
Liquid
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.
Suction
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 50 microns.
Note: If tubes are connected to the IMS, evacuate
the vapor & suction lines to get the entire system.

·
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.
·
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.
