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
1
1 ⁄
4
" I.D.) are required for draining.
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 legs. They will screw into threaded holes in the base of the unit.

Installation: Sealing Unit
If the unit is to be sealed to the counter top, the drain 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
1. Sanitize the ice storage system as instructed on page 9.
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 and the lighted sign should come on.
Dispense several containers of ice.
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.

FOR THE OPERATOR
This section covers operating controls, daily pre-operation check, and unit operation.
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.
The dispenser must always contain ice to have ice available for use.
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. At the front of the hopper 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.
Note: Ice On The Bottom of The
Hopper Will Not Be Dispensed.

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.
4. Remove the ice chute (if used) by lifting one end and pulling out of the slots. Unscrew the sweep arm from the rotor shaft, and pull the rotor from hopper.
7. Lift up & out and remove the upper front panel.
A. Twist the clear ice chute 1/3 turn, and pull down to remove.
B. Locate the two thumb screws holding the upper ice chute; remove them (1 on top and 1 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.

Place the clear ice chute back onto dispenser.
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, 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.
11. Pour in fresh, sanitary ice and replace the cover. Plug the unit in, and it is now ready to dispense ice.

SERVICE DIAGNOSIS
PROBLEM
Will not dispense ice
PROBABLE CAUSE
1. No ice in hopper
2. Vend switch does not close
3. Drive motor will not run
4. Door solenoid will not open door
5. Rotor will not turn
6. Relay for vend switch does not close during operation.
CORRECTION
1. Fill hopper with ice
2. Check vend switch, replace if open
3. Check drive motor, replace if not working
4. Check/replace door and solenoid
5. Check hub of rotor
6. Check relays, replace if necessary.
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.
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.
