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 below the hopper; and it
dispenses beverages via post-mix or pre mix
valves. One of the valves (2nd from left) is not
carbonated; it may be changed to carbonated if
desired. Power to operate the valves may be shut
off by a key switch.*

An important feature of this dispenser is that the
ice on the cold plate is not dispensed.
* 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
dispense cubed or Nugget ice only. Flaked ice will

not work.

THE CABINET MUST BE

LEVELED LEFT TO RIGHT

AND FRONT TO BACK

RS100 and RS150

FOR THE INSTALLER

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.

The syrup and carbonated water connections need
to be made at the cold plate’s stub lines. The cold
plate is located under the hopper; stub lines are at
the back of the cabinet.

Note: Beginning with RS100, sn 594922-06Y and
RS150, sn 594966-067, cold plate connections are
at the front of the unit, behind the splash panel.

Tubing routing to the cold plate is from either the
back of the unit, or through any of the 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.
A. If no legs are to be used, and the tubing must

pass through the base, a hole in the counter top
must be made prior to sealing the unit to the
counter.

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.

B. If using legs, the tubing may be routed through
the bottom, or through the back as desired.

3. Plan the unit drain. Two

3

⁄4" I.D. drain tubes are

located at the back inside of the cabinet. The tubes
may drain the unit through the back or through the
openings in the base. There are several different
fittings shipped with the unit to allow different drain
tube configurations.

4. 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 optional leg kit (KLP5). They will screw into
threaded holes in the base of the unit.

If the unit is to be sealed to the counter top, the
drain and soda tubing should be available and
planned such that the connections may be finished
after the unit has been sealed to the counter.
Sealing may be accomplished by the use of room
temperature vulcanizing (RTV) rubber sealant
such as General Electric IS 808 Industrial Sealant,
Dow Corning 731 or the equivalent.

FOR THE INSTALLER

RS100 and RS150

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 any shipping materials.

INSTALLING DRAIN AND SODA LINES

Refer to the plumbing schematic on the back of
the cabinet (all stub lines are labeled) and:

A. Connect three (for 6 Valve Units) or two (for
8 valve units) 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 line (field supplied)
from building source to carbonator (filtered water
is recommended).

C. Connect a water supply line to the plain water
stub line 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 to the cold
plate syrup stub lines.
