The operation of the Q Series ice dispenser can be
divided into three main operations. They are Dispenser
Activation, Ice Pick-Up and Ice Delivery.
Dispenser Activation
Dispenser activation can be accomplished with a
number of different mechanisms.
• Rocking Chute (Push for Ice) Activation –User
pushes the Rocking Chute, which energizes a
microswitch. The energized microswitch engages
the gearmotor.
• Room Key Card Activation – User places their
hotel room key card into a slot on the dispenser.
The room key card activates the microswitch. The
user then presses the Rocking Chute (Push for Ice)
for ice dispense. This action activates the
gearmotor.
• Coin Operated Activation – User places one
quarter into dispenser. The quarter activates the
coin mechanism. The user then presses the Rocking
Chute (Push for Ice) for ice dispense. This action
activates the gearmotor.
Ice Pick-Up
When the customer activates the dispenser, the
gearmotor inside the dispenser begins to turn.
The gearmotor shaft is attached to the paddle wheel
inside the bin of the dispenser. As the paddle wheel
turns it picks up ice from the dispenser bin. The paddle
wheel will bring the pocket containing the ice to the top
of the travel area.
Ice Delivery
When the paddle wheel pocket reaches the top of its
travel, the ice falls from the paddle wheel to the ice
chute opening of the dispenser bin. The bin chute then
directs the ice to the door assembly.
If the door closes before all the ice is dispensed, some
ice may be held back by the door assembly. If the door
is open, the ice will fall through the door and the ice
chute. The ice chute will direct the ice into the
customer’s container.
Model QFA-291 is equipped with an optional water
valve. When the water valve lever is pressed, water
flows through the system to the water valve nozzle.

General Information Section 1
Room Key Card Activation
Coin Operated Activation
1. User places ice bucket under ice chute.
2. User places their hotel room key card into a slot
on the dispenser which is labeled “Insert Room
Key Card”. The room key activates the
microswitch.
3. The user then presses the Rocking Chute (Push
for Ice) for ice dispense. Pushing the ice chute
activates the gearmotor.
The room key card must stay in the slot for the
microswitch to remain activated.
1. User places ice bucket under ice chute.
2. User places one quarter (U.S. currency only) into
dispenser.
3. The user then presses the Rocking Chute (Push for
Ice) for ice dispense.
Pushing the ice chute activates the gearmotor. Ice
will dispense for up to one minute for each 25 cent
activation per factory setting.
Important
Coin Operated Activation will accept U.S. quarters
only. No other coin is accepted and no change is
returned to the user. To allow use of Canadian
coins, please contact your local dealer.

Section 1 General Information
Adjusting the Coin Mechanism Timer
1. Remove the control box cover. On the inside of
the control box there is a white instruction label
which shows how to set intervals for coin
mechanism dispense times.
2. Inside the control box, the coin mechanism timer
is to the left. The ice agitation timer is to the
right.
3. With a small Phillips head screwdriver, adjust the
coin mechanism timer. For timer adjustment
reference information, see below or refer to the
white instruction label inside the control box
cover.
4. The timer is factory set at the midpoint (as shown
above) for 60 seconds of dispense time.
The adjustment pot can be set (counterclockwise)
for as low as 12 seconds of dispense time.
The adjustment pot can be set (clockwise) for as
high as 120 seconds of dispense time.

General Information Section 1
Adjusting the Coin Mechanism for Canadian Coins
Important
Canadian quarters are magnetic. Therefore the
magnet inside the coin mechanism must be
removed so Canadian quarters will drop through
the coin mechanism.
1. Remove the front panel of the dispenser. The
coin mechanism can be changed while in place in
the dispenser door, as shown above.
2. Pivot the coin magnet housing section away from
the rest of the coin mechanism.
3. Using a small screwdriver, loosen the set screw
which holds an aluminum plate in the coin
magnet housing.
4. Remove the aluminum plate.
5. Using a metal screwdriver tip, pull out the magnet
from the magnet housing. (The backside of the
magnet has the stronger magnetic attraction.)
6. The aluminum plate and magnet have now been
removed from the coin magnet housing. Pivot the
empty coin magnet housing section back into
place.
7. Reinstall the front door of the dispenser.

Installation Section 2
Pre-Installation Checks
1. Location: Floor drain available - A floor drain
for the dispenser should be available. We
recommend that you vent the drain at the back of
the dispenser to reduce buildup of algae and
improve drainage. Drain tubing should be ½” I.D.
at minimum.
2. Location: Avoid heat sources – Avoid placing
the ice machine near heat sources such as
radiators, heating vents and direct sunlight. Avoid
placing air-cooled ice machines in kitchens, due to
grease, flour, or other particles, which can collect
on the condenser and fan blade, increasing ice
machine maintenance and reducing ice machine
efficiency.
3. Location: On a solid floor – The dispenser and
ice maker should be sitting on a good, solid, level
floor or surface.
4. Location: Do not obstruct traffic – The
dispenser should not extend from the wall in a
way that obstructs traffic through the area.
5. Electrical – Proper electrical voltage is available.
Receptacle is available and
within six feet.
The dispenser must be grounded in accordance with
all local and national electrical codes.
WARNING
Never use an extension cord. If an electrical outlet is
not within six feet, have proper amperage outlet
installed.
6. Clearances for top and both sides of ice
machine – Use clearances specified in the ice
machine’s Installation and Use & Care Guide.
7. Clearance behind ice machine for dispenser
and drains – The location must allow enough
clearance for the water and drain connection at the
rear of the dispenser.
8. Back of ice machine to be flush with back of
dispenser – This allows easy removal of dispenser
front panel.
9. Separate drains – a separate drain line is required
for the ice machine, in addition to a drain line for
the Q Series Dispenser. Vent all drain lines.
10. Water filtration – Water filtration is strongly
recommended in order to increase the performance
of the ice machine and reduce maintenance costs.

including plumbing lines, connections and electrical
requirements, see the ice machine installation manual.
