INSTALLATION

DCE33

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

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.

F., and the maximum is 1000F.

Water Quality:

Ice made by the DCE33 will have a lower mineral content than the water it was made from.

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:

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.

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 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.

Page 4

TO INSTALL: Plumbing

DCE33

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.

TO INSTALL: Plumbing

Free Standing Cabinet, Gravity Drain Model:

All horizontal runs of drain lines must have a 1/4" per foot fall. An air gap will 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

" 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.

Reversing Door Swing:

The hinged side of the door may be reversed to the other side if desired:

The DCE33 was shipped with the door hinged at the right. The door and hinges are designed for placing the hinges on either the right or the left side of the cabinet. Moving the hinges to the left allows the door to pivot from the left side.

Note: There is a part, packed with the machine, that is required for this procedure.

1. Open the door and remove the three screws holding the lower hinge to the cabinet.

2. With the door open enough to see both screws at the top door hinge, remove the two screws. The door is now free of the cabinet.

3. Remove the single screw and the hinge filler plate from the top of the door.

4. Install the other filler plate (shipped inside refrigerator compartment) onto the top corner of the door where the hinge was.

5. Remove the three plastic plugs from the top front corner where the hinge will mount.

6. Remove the three plastic plugs from the lower front corner where that hinge will mount.

7. Remove the three screws holding the top hinge to the cabinet. Remove that hinge from the top and, flipping it upside down, install it onto the bottom of the door, on the opposite side using the original screws.

Initial Start Up - DCE33A-1BD, DCE33PA-1BD, DCE33A-1SSD or DCE33PA-1SSD

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

" high. When the

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.

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.
