IN STAL LA TION
To properly make and store ice, the DCE33
requires access to air, potable water, 115 volt
electricity and a drain. The machine must be
installed indoors, in a controlled environment.
Air: The ice machine uses a fan to take in room air
at the front of the machine through the right side of
the kick plate. It discharges warm air out the left
side of the kick plate. Anything placed in front of
the kick plate will restrict air flow and cause a
decrease in performance and efficiency. The
minimum air temperature the machine will operate
in is 50
Water Supply: The ice machine requires a
continuous supply of potable water at no less than
20 p.s.i.g. of flowing pressure. Static water
pressure should not exceed 80 p.s.i.g. The
minimum water temperature the machine will
operate in is 40
Water Quality:
There is no such thing as “pure” water; all water,
including potable water supplied by municipalities,
contains some “impurities”. Water absorbs
impurities from the air as rain and/or as it flows
through the ground. Some of the impurities are
solid particles, these are known as suspended
solids, and a fine particle filter will remove them.
Other impurities are chemically bonded to the
water molecules, and cannot be filtered out, these
are called dissolved solids.
Ice made by the DCE33 will have a lower mineral
content than the water it was made from.
Purer water will freeze first in the ice making
molds. The reason for this is that anything
dissolved in water lowers the water’s freezing
temperature.
This concentrates most of the impurities in the ice
machine water reservoir where they may form hard
deposits known as scale. The DCE33 dilutes the
concentration of minerals by over-filling the
reservoir during the harvest cycle (with the excess
water flowing down the drain). About 3 quarts of
water flow into the unit each cycle. About 1 quart
of that rinses the reservoir and goes down the
drain.
0
F., and the maximum is 1000 F.
0
F., and the maximum is 1000 F.
To keep the machine operating properly, these
impurities or minerals will have to be regularly
dissolved by an acid cleaning, using Scotsman Ice
Machine Cleaner. Directions for this may be found
in the section under cleaning.
In general, it is always a good idea to filter the
water. A water filter, if it is of the proper type, can
remove taste and odors as well as particles. Some
methods of water treatment for dissolved solids
include reverse osmosis, and polyphosphate
feeders. A reverse osmosis system should include
post treatment to satisfy the R.O. water’s
“aggressiveness”.
Deionized water is not recommended.
Because water softeners exchange one mineral for
another, Scotsman does not recommend their use
for ice machines. Where water is very hard,
softened water may result in white, mushy cubes
that stick together.
Scotsman suggests, that if in doubt about the
water, that a local point of use water specialist be
contacted for recommendations on water
treatment.
Electricity: The machine is supplied with a cord,
and may be plugged into a wall outlet. The ice
machine should be the only device using that
circuit.
The fuse (or circuit breaker) size should be 15
amps.
Drain: There are two DCE33 models:
The DCE33A-1 is a gravity drain model that
requires a drain tube that’s pitched down from the
outlet at the back of the cabinet to the connection
to the sanitary sewer.
The DCE33PA-1 has a built in drain pump that will
pump water up to a drain point, such as a nearby
sink.
Some impurities will inevitably remain, and will
stick to the parts in the machine, and will cause
malformed ice cubes. Eventually, built up mineral
scale can shorten machine life.

The water supply and drain should be roughed in
and ready at the point of installation. A wall outlet
directly behind the ice machine will make
undercounter installation easier. All electrical,
water and drain connections must conform to local
codes.
Installation Cautions: Although the DCE33 has
been designed to be serviced in place, in some
cases it may be necessary to pull the unit out for
service. For that reason do not restrict access to
the cabinet at the front - top and bottom.
Install Unit
Flush With Floor
Installations on a slab: Use a pump
(DCE33PA-1) model and pump the water to the
point of drainage. Pump models will pump 1 story
high.
Installations over a crawl space or basement:
Either gravity drain or pump model units may be
used, if there is not enough room behind the
machine for a drain/waste receptacle, the drain will
have to be below the floor.
ALL PLUMBING MUST MEET LOCAL CODES
Note: When installed in a corner, the door
swing may be limited due to handle contact
with the wall or cabinet face.
Shims
If a floor is to be installed after the ice machine,
shims the thickness of the floor should be installed
under the DCE33 to keep the machine level with
the floor. Also, allow 1/8" clearance on each side of
the cabinet.

Final Check List
1. Has the machine been properly uncrated, and
have all packing materials and tape been removed
from inside the bin?
2. Have the installation instructions been followed,
including connecting the machine to water, drain
and electricity?
3. Has the machine been leveled?
Initial Start Up
1. Turn on water supply.
2. With unit plugged in, rotate ice machine control
knob to the ON position.
3. Allow the unit to operate for 1 hour, and check
the size of the cubes, if they are not correct, adjust
as recommended on page 18.
4. After the cubes are confirmed to be the correct
size, replace all panels.
5. Locate the nameplate on the control box cover.
Record the serial number and date of start up here
in the manual. Keep the manual handy for future
reference.
Serial Number:___________________________
Date of initial start up:_____________________
6. Fill out and mail the Warranty Registration.
How To Use:
The ice machine is extremely simple to use, just
turn the ice machine control knob to the on
position. The DCE33 will automatically begin to
freeze ice and will continue to do so until the bin is
full. A new machine, warm out of the box, could
take as long as 48 hours to fill and shut off.
Use the scoop to remove ice and place the ice
scoop in the holder provided (do not leave the
scoop on the ice, as it will gradually disappear into
the ice).
What to expect from the DCE33
The DCE33 will release a batch of 8 ice cubes
about every 30 minutes. At the same time the
cubes fall into the storage bin, water will be
entering the ice machine and draining out.
Ice: The ice cubes are tapered cylinders about 1
in diameter at the widest end; taper down to 1"
wide at the top; and are 1
1
" high. When the
8
machine is adjusted properly, there should be a
indent in the base of the cube. The ice will appear
wet when fresh, this is normal. It may also develop
frost on the outside and look cloudy - this is also
normal (the frost will disappear when liquid is
poured over the ice).
Storage: All restaurant type ice machine operate
on this principal: The ice storage bin is not
refrigerated; instead it’s heavily insulated, much
like a picnic cooler or ice chest. If the ice bin were
to be refrigerated, the ice would freeze together
into one very large cluster of ice, and would begin
to evaporate. This would yield ice that is very poor
in quality, and difficult to remove from the machine.
1
4
1
"
4
"
The DCE33 will continue to operate until ice builds
up high enough to contact the bin thermostat
sensor tube, then it will shut off. Models with a
drain pump will occasionally pump out melt water
when the machine is off. The pump will only be on
for a few seconds.
Run Time: The amount of time the DCE33 will run
to replace melted ice is about 6 hours per day. The
amount of time the ice machine will run to replace
ice removed is dependent upon how much is
removed, how clean the ice machine is, and how
hot the air and water supplied to the machine are.
A machine that has been emptied will usually take
about 24-36 hours to re-fill.

MAIN TE NANCE AND CLEAN ING
What shouldn’t be done?
Never keep anything in the ice storage bin that is
not ice; objects like wine or beer bottles are not
only unsanitary, but the labels may slip off and plug
up the drain.
Never allow the machine to operate without regular
cleaning. The machine will last longer if it is kept
clean. Regular cleaning should happen at least
once per year, and preferably twice. Some water
conditions will dictate even more frequent cleaning
of the ice making section, and some carpets or
pets will dictate more frequent cleaning of the
condenser.
What should be kept clean?
There are 5 things to keep clean:
1. The outside cabinet & door.
2. The ice storage bin.
3. The condenser.
4. The ice making system.
5. The ice scoop.
How to clean the condenser.
The condenser is like the radiator on a car, it has
fins and tubes that can become clogged. To clean:
1. Remove the kickplate.
2. Locate the condenser surface.
3. Vacuum the surface, removing all dust and lint.
Caution: Do not dent the fins.
Condenser
Surface
4. Replace the kickplate.
Winterizing
1. Clean the machine as explained on the next
page.
How to clean the cabinet.
Wipe off any spills on the surface of the door and
handle as they occur. If anything spilled on the
door or gasket dries onto the surface, wash with
soap and warm water to remove.
How to clean the ice storage bin.
The ice storage bin should be sanitized
occasionally. It is usually convenient to sanitize the
bin after the ice making system has been cleaned,
and the storage bin is empty.
A sanitizing solution can be made of 1 ounce of
household bleach and two gallons of hot (950F. 1150F.) water. Use a clean cloth and wipe the
interior of the ice storage bin with the sanitizing
solution, pour some of the solution down the drain.
Allow to air dry.
Note: To use after winterizing,
reconnect pump hose and water line.
Repeat Initial Start Up.

2. Turn off the water supply.
3. Drain the water reservoir. See page 24, Spray
Pump Repair and follow the instructions to remove
the pump hose (step 2, bottom hose only).
4. Disconnect the incoming water line at the inlet
water valve.

How to clean the ice making system.
1. Open the door and
turn the ice machine
control knob to off.
2. Scoop out all of the ice, either discard it or save
it in a ice chest or cooler.
3. Pour 4 ounces of Scotsman Clear 1 Ice Machine
Cleaner (available from a local Scotsman
Distributor or Dealer), into the ice machine
reservoir.
4. Turn the ice machine control to ON.
5. Allow the machine to operate for about 2 hours.
6. Pour hot (950F. - 11 50F.) water into the bin to
melt the ice that has formed. That ice will likely be
white and frosty looking.
7. Clean the bin liner of mineral scale by mixing
some ice machine cleaner and hot water, and
using that solution to scrub the scale off of the
liner.
8. Rinse the liner with hot water.
9. Sanitize the bin interior.
10. Replace the ice removed in step 2.
The ice scoop should be washed regularly, wash it
just like any other food container.
Scotsman Ice Machine
Cleaner contains acids.
These compounds may
cause burns.
If swallowed, DO NOT
induce vomiting. Give
large amounts of water or
milk. Call Physician
immediately. In case of
skin contact, flush with
water. Keep out of the
reach of children.
Note: Over time biofilm can grow inside the drain
system which can affect the ability for the drain
system to evacuate the drain water. On the pump
models this can also drive a erratic pump
operation. Including the pump cycling rapidly or
running all the time. Biofilm and pump cycling
issues will eventually lead to low production and
standing water in the bin. To ensure that this does
not become an issue frequent bin sanitizing may
be required.

Bin’s ice level.
When the ice machine shuts off the ice level in the
bin should be even with the metal tube inside the
bin. If the ice in the bin is too high or low, turn the
ice machine control knob to adjust the bin
thermostat.
1. To lower the ice level, turn the knob
counterclockwise. Usually a 1/8 turn will be
enough.
2. To increase the ice level, turn the knob
clockwise. Usually a 1/8 turn will be enough.
Harvest Time Adjustment
The harvest time can be adjusted so that all the ice
is released during the harvest period, with a few
seconds extra for a safety margin. The adjustment
range is between 2 to 5 minutes.
There is an adjustment screw on the surface of the
electronic timer. Rotate the screw CCW to reduce
harvest time, and CW to increase it. It should be set
to match the machine's performance. If the machine
takes 2 and a half minutes to release the ice, the
harvest time should be set to about 3 minutes.
