INTRODUCTION
DCE33
The Scotsman DCE33 is a restaurant type ice
machine designed for home use. It produces the
same high quality ice as large Scotsman
commercial ice cube machines, and stores that ice
in a heavily insulated storage bin.
This service manual is intended as a resource for
people installing, using, and servicing the DCE33.
Because it contains information on safety and
maintenance, Scotsman strongly recommends that
this manual be kept where it is readily available.

INSTALLATION
DOE33
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 500 F., and the maximum is 100 ° F.
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 400 F., and the maximum is 100 ° F.
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 witl 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 witl 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.
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.

DCE33
TO INSTALL: Plumbing
The water supply and drain should be roughed in
and ready at the point of installation. A walt 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
lush With Floor
Installations on a slab: Use a pump
(DCE33PA-1 B) model and pump the water to the
point of drainage. Pump models wilt 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.

Model:
All horizontal runs of drain lines must have a 1/4"
per foot fall. An air gap wilt likely be required
between the ice machine drain tube and the
drain/waste receptacle. A stand pipe with a trap
below it would be acceptable for the drain/waste
receptacle. A floor drain is also acceptable.
FOLLOW ALL LOCAL PLUMBING CODES
Poor draining will cause a high rate of ice
melting in the bin.
1. Remove the kick plate and the access cover
above it.
2. Route the water supply, which should be a 1/4"
O.D. copper tube through the back of the cabinet
to the front.
3. Install a flare nut and flare the end of the tube.
4. Flush the water line and fasten the flare nut to
the male flare on the inlet water valve.
5. Route a 5/8" ID (7/8" OD) drain tube through the
back panel of the machine and connect to the bin
drain fitting at the bottom of the bin. Secure with
hose clamps.
Be certain that the drain tube is pushed up well
past the barbs on the drain fitting. If needed to
ease installation, soak the drain hose in hot water
just before connecting to the fitting.
6. Route the drain tube from the ice machine to the
drain/waste receptacle. Note: if using a long
horizontal run (more than 5') the drain should be
vented at back of cabinet.
7. Turn on the water supply and check for leaks.
8. Replace the kick plate and the access cover
above it.
9. Level the unit using the leg levelers.
