SPECIFICATIONS
The term “Refreshment Stand” means a machine
that stores ice in an insulated, sanitary container;
upon demand it dispenses that ice into a cup or
glass; it cools beverages using ice falling from the
hopper onto a cold plate at the base of the hopper;
and it dispenses beverages via post-mix or pre mix
valves. Some of the valves are not carbonated;
they may be changed to carbonated if desired.
Power to operate the valves may be shut off by a
key switch.*
* Premix is not electrically powered.
The RS requires additional equipment to be
functional:
An ice machine or source of sanitary ice; a
carbonator for post mix (and potable water); a
syrup delivery system, either pressurized syrup
cans or bag-in-a-box; and CO
must also be connected to a drain.
NOTE: This Refreshment Stand is designed to

FOR THE INSTALLER: Tubing Installation
1. Locate the dispenser on the counter. Allow
vertical clearance above unit for the removal of the
cover, and for pouring ice into the hopper.
Note: If installing an ice cube machine on top,
check for proper total cabinet clearance, including
adapter kit.
The syrup and carbonated water connections need
to be made at the cold plate’s stub lines. The cold
plate stub lines are behind the splash panel.
Tubing routing to the cold plate is from either the
back of the unit, or through openings in the base.
A plumbing circuit schematic diagram is on the
back of the cabinet, refer to it for cold plate
connections.
2. Plan the routing of the tubing (drain and soda).
If the tubing will pass through the base, a hole
in the counter top must be made prior to
sealing the unit to the counter.
The tubing may also be routed through the back.
3. Connect the drain system. There are two drains
to connect: The sink (or drip tray) drain and the
cold plate drain. They must be routed separately.
The tubes may drain the unit through the back or
through the openings in the base.
Drip Tray/Grill
1. Remove splash panel from unit.
2. Connect the sink drain hose to the sink drain
fitting and secure it with a hose clamp. Route the
tube to the building drain. Follow all local plumbing
codes.
4. Hang the drip tray onto the metal tabs on the
base of the unit.
5. Replace the splash panel.
Note: If the cabinet has been sealed to the
countertop, add sealant around the sink and
counter top to provide a seal with a radius of 1/2".
Follow the sealant manufacturer’s instructions on
the package for working with the sealant, and
cleaning up.

FOR THE INSTALLER: Sealing of Cabinet
In order to comply with National Sanitation
Foundation (NSF) requirements, this unit must be
either elevated above the counter top sufficiently to
provide space for cleaning under the unit or
sealed to the counter top.
Elevating the unit may be accomplished by using
the leg kit. Legs screw into threaded holes in the
base of the unit.
If the unit is to be sealed to the counter top, the
soda tubing installation should be planned such
that its connections may be finished after the unit
has been sealed to the counter.
Seal the unit by the use of room temperature
vulcanizing (RTV) rubber sealant such as General
Electric IS 808 Industrial Sealant, Dow Corning
731 or the equivalent.
With the unit located on the counter as desired:
A. Tilt or lift the unit to expose the bottom flanges
of the base frame.

B. Apply the sealant to cover the bottom flanges of
the base frame.
C. Return the unit to the desired position on the
counter top.
D. Add sealant around the base frame and counter
top to provide a seal with a radius of 1/2". Follow
the sealant manufacturer’s instructions on the
package for working with the sealant, and cleaning
up.
E. Seal around all access holes in the counter top
with Permagum or Mortite caulk or an equivalent
material.

FOR THE INSTALLER
1. If installing a carbonator, locate it nearby.
2. Route the drain lines to the building drain. Vent
the drain tubes if installing at the back of the
cabinet.
3. Locate electrical supply (for cord - 115v outlet).
The outlet must be properly grounded. The
circuit must be fused and no other electrical
appliance should be on the circuit.
ALL ELECTRICAL WIRING MUST CONFORM
TO NATIONAL AND LOCAL CODES
4. Remove splash panel.
Refer to the plumbing schematic on the back of
the cabinet (all stub lines are labeled) and:
Typical Installation
A. Connect carbonated water supply lines (field
supplied) from the remote carbonator to the
carbonated water stub line at the dispenser cold
plate.
B. Connect water supply lines (field supplied)
from building source to carbonator (filtered water
is recommended).
C. Connect water supply line(s) to the plain
water stub line(s) on the cold plate for use with
the non-carbonated valve.
NOTE: If ALL valves need carbonation, connect
an additional carbonated water line from the
carbonator to the plain water stub line on the
cold plate.
D. Connect syrup lines from the syrup supply to
the cold plate syrup stub lines.

Installation: Scotsman Slim Line Cuber
Assembly:
The assembly of the ice machine onto the
dispenser requires two additional parts: an adapter
and a thermostat stand off kit.
1. Mark two spots on the inside left liner of the
dispenser: 2" down from the top, 4" from the back,
and 4" apart.
2. At the two marked spots, drill two 1/4" holes thru
the plastic liner only.
3. From the stand off kit, locate the stand offs and
plastic anchors. Thread the stand offs partially into
the plastic anchors.
4. Push the anchors/stand offs into the holes
5. Screw the stand offs all the way into the
anchors. Be sure that the holes in the stand offs
are horizontal.
6. Place a bead of silastic (from the kit) around the
stand offs.
7. From the adapter kit, place the stainless steel
adapter onto the top of the dispenser. Follow all
directions included with the kit.
8. After the ice machine has been placed on the
dispenser, remove the front panel and uncoil all of
the bin thermostat capillary tube.
9. Route the capillary tube thru the front hole in the
base of the ice machine, to the left side if the
dispenser towards the stand offs.
10. Route the end of capillary tube thru the
stand-offs, bend the tube around the stand offs so
that it does not fall off.
11. Check that the routing of the capillary tube is
away from the ice chute and up high enough near
the base of the ice machine.
