FOR THE INSTALLER

1. Locate the Ice Station on the counter.
Allow vertical clearance above unit for the
removal of the cover, and for pouring ice
into the hopper.

2. Plan the unit drain. Two tubes (5/8" and
3/4" I.D.) are located at the back of the
cabinet. Routing is either thru the back or
base. Sufficient fittings are indluded with
the unit to install in most cases.

3. 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 legs. They will screw
into threaded holes in the base of the unit.

CABINET DRAIN

TUBES

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 (Scotsman part number 19-0529-01)
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.

INITIAL START UP

IS100 and IS150

1. Sanitize the ice storage system as instructed on
page 8.

2. Fill hopper with sanitary ice.

Ice hopper contains parts
that can move at any
time, and will cause
injury if hands are in the
way.

Do

not remove cover

until the unit has been
unplugged from the
electrical power.

3. Plug the unit’s power cord into an electrical
outlet, if the unit has a lighted sign, it should come
on. Dispense several containers of ice.

FOR THE OPERATOR

This section covers operating controls, daily
pre-operation check, and unit operation.

Note: there is a timer in the control box that will
activate the rotor in the ice bin every two hours.
The amount of time that the rotor turns is factory
set at 2 seconds, and is adjustable between one
tenth of a second and 4 seconds. Agitation of the
ice keeps it from fusing together after long periods
in the bin.

The dispenser must always contain ice to have ice
available for use.

OPERATING CONTROLS - Units have either a
lever or a push button.

Lever: Ice will continue to be dispensed for as long
as the lever is held in, or until the hopper is empty.

Push Button: When the ice dispense button is
pushed, ice will be dispensed for as long as the
button is held in or until the hopper is empty.

Daily Check

1. Make sure drip tray and grill are clean.

2. Remove cover and pour sanitary ice into the
hopper.

Do NOT use bagged ice directly from a freezer.
The ice must be broken up in the bags first before
adding to the hopper.

Large chunks of ice can NOT be dispensed.

Keep the cover in place, and check the ice supply
regularly during operating hours.

3. Keep sink clear of spilled ice.

4. At the end of the day:
Remove the grill from the sink, clean the sink, grill

and splash panel, make sure the sink drain is open
by pouring hot water into the sink. Return the grill
to the sink.

HOW IT WORKS

The ice is stored in a hopper, and the hopper is
sloped towards the front. At the front there is an
angled rotor: when that rotor turns, it scoops the
ice, lifts it to the top of the ice chute and drops it
through that chute into the user’s container.

CLEANING AND SANITIZING

The sink, grill and splash panel area should be
cleaned daily.

The ice storage system should be sanitized
monthly.

Daily:

1. Lift up and remove grill from sink.

2. Use soap, hot water, and a clean cloth to wash
sink and splash panel; rinse with hot water,
allowing plenty of hot water to run down the drain.

3. Wash the grill, then rinse with clean water. Place
back in sink.

4. Clean all exterior surfaces of the unit with warm
water and a sponge. Rinse out the sponge with
clean water, wring excess water out of the sponge,
and wipe off external surfaces of the unit. Wipe unit
with a clean soft cloth. Do NOT use abrasive type
cleaners.

CLEANING AND SANITIZING

MONTHLY & INITIAL START UP:
Sanitize the Ice Storage System.

Note: this should only be done by qualified
personnel.

1. Unplug the Ice Stand’s electrical cord from the
electrical power.

Ice hopper contains parts
that can move at any
time, and will cause
injury if hands are in the
way.

Do

not remove cover

until the unit has been
unplugged from the
electrical power.

2. Remove cover and discard all remaining ice.

3. Mix a solution of 1 ounce of household bleach to
2 gallons of potable water, or: mix a solution of any
approved sanitizer, following the directions for
mixing and applying that sanitizer.

A. Twist the clear ice chute 1/3 turn, and pull down
to remove.

B. Locate the two
thumbscrews holding
the lower brace.
Remove them and the
brace.

C. Locate the three
thumb screws holding
the upper ice chute;
remove them (1 on

CLEAR
CHUTE

top and 2 below).
Remove the upper ice
chute from the
machine.

Thoroughly wipe the surfaces of the bin door and
both ice chutes with the sanitizing solution, and
allow to air dry.

4. Remove the ice chute (if used) by lifting one end
and pulling out of the slots. Unscrew the sweep
arm (plus shield and bearing if used) from the rotor
shaft, and pull the rotor from hopper.

Place the upper front panel back onto the machine.

8. Wipe the inside surface of the cover with the
sanitizing solution, and allow to air dry.

9. Reassemble the rotor and hopper (plus ice
chute, shield and bearing if used, re-wipe the
surfaces of the rotor and allow to air dry.

10. Wipe the top edge of the ice hopper with the
sanitizing solution, allow to air dry.

SERVICE DIAGNOSIS

PROBLEM PROBABLE CAUSE CORRECTION

Will not dispense ice 1. No ice in hopper 1. Fill hopper with ice

2. Vend switch does not close 2. Check vend switch, replace if
open

3. Drive motor will not run 3. Check drive motor, replace if
not working

4. Door solenoid will not open

door

5. Rotor will not turn 5. Check hub of rotor

6. Relay for vend switch does

not close during operation.

ELECTRICAL SEQUENCE

Refer to the wiring diagram.

Ice Vending:

Ice is dispensed as long as the ice vend lever or
push button is pushed, or until the hopper is empty
of ice.

••When the ice vend lever or push button is

pushed, the vend switch closes, and makes a
circuit to the coil of relay A.

••When relay A is energized, relay A’s contacts

6-9 and 7-4 close. Relay A’s contacts 7-1 open.

••When relay A’s contacts 6-9 close, they make a

circuit to the door solenoid, which opens the ice
door.

••When relay A’s contacts 7-4 close, they make a

circuit to the coil of relay B.

••When relay A’s contacts 7-1 open, the circuit to

the timer is opened.

••When relay B’s coil is energized, it closes a

circuit to the gearmotor, and the motor turns the
rotor.

4. Check/replace door and
solenoid

6. Check relays, replace if
necessary.

Stand By:

••Relay A’s contacts 7-1 are closed and make a

circuit to the timer.

••The timer is energized when the unit is not

dispensing. The timer switch will close for a few
seconds every two hours.

••When the timer switch is closed, it makes a

circuit to relay B’s coil.

••When relay B is energized, it powers the

gearmotor, and the rotor is turned.
