SLD150
Introduction
To the owner or user: This product manual is a source of information about the installation, start up, cleaning, maintenance and repair of the product.
The SLD150 is a Slim Line® brand hotel/motel ice dispenser. It is designed to use a Scotsman Slim
Line SLE300 or SLE400 ice machine as the source for ice.
Ice from the cuber falls into the insulated hopper, where it is stored until needed. When a user pushes the dispense button a rotating wheel scoops the ice up to the top front of the hopper where there is an outlet to the ice chute.

Installation: General
After the carton has been removed from the dispenser, the legs may be installed.
Place flat portions of the carton on the floor behind the dispenser and lay the dispenser down on its back.
Thread the legs into the base of the dispenser. Be sure that the legs are screwed in all the way. Turn the leg levelers in all the way.
Move the dispenser to an upright position and set it in the location where it will be installed. Note where drain lines and electrical connections will be made.
Drain:
The dispenser has a 3/4" FPT drain fitting at the bottom center of the back panel. Connect 3/4" rigid tubing to this connection, a vent is recommended for most installations. Route the drain tubing to the building drain. Follow all applicable plumbing codes.
Because the drain tubing will be very cold, insulation is recommenced.
Electrical:
There is an electrical junction box on the lower back panel
Make the electrical connections there. Follow all applicable electrical codes. Use a licensed electrician.
The dispenser must be installed so that it is a separate piece of equipment from the ice machine.
The drains and electrical supply must be separate.
Note
Remove any packing material from inside the storage bin. Retain keys for later use.
Check that gasket tape is on the top outside edge of the dispenser where the ice machine will rest.

Installation: Ice Machine
Check that gasket tape has been placed at the outside edge of the dispenser top.
Place corner posts from the carton on top of the dispenser, at the left and right front corners.
Locate bin thermostat bracket entrance hole, its found at the right side of the hole in the top of the dispenser. Make sure the hole is open.
Place the ice machine onto the dispenser. The ice machine is heavy, use of a mechanical hoist is recommended.
The ice machine should be tilted up slightly. Uncoil about 18" of bin thermostat capillary tube.
Push the end of the capillary tube thru the plastic tube located to the left of the compressor.
Observe the tube as it pushes down out of the base. Adjust the position of the ice machine so that the capillary tube enters the hole for the dispenser’s bin thermostat bracket.
Carefully remove cardboard supports and allow ice machine to rest on dispenser gasket.
Caution: Bin thermostat capillary tube must not be kinked or broken during installation.
Follow all instructions for installation of the ice machine.

Final Check List/Initial Start Up
1. Check that electrical power has been supplied.
2. Check that a drain, separate from the ice machine, insulated and made of rigid tubing, has been connected to the dispenser.
3. Check that the ice machine has been properly installed per the ice machines installation directions.
4. Check that the ice machine/dispenser assembly is level front to back and left to right.
5. Check that optional kits, if any, have been correctly installed.
6. Check that the sink key, and coin box key if used, are available.
To Start:
1. Connect electrical power.
2. Go thru ice machine start up procedures. Let ice machine make two harvests.
3. Push vend switch button in.
4. Rotor should rotate 1/4 turn and stop.
5. Ice will be dispensed from ice chute.
6. Remove sink, and check drain area for leaks. If none, replace sink.
7. Fill out the warranty registration form and place it in the mail.
8. Give the operator the key(s) and instructions on the operation and maintenance of the product.
Check that the operator knows who to call for service, and has the product/service manuals for the machines.
Electrical Sequence
Pushing the vend button closes a contact to the gear motor (and to the ice door solenoid of
SLD150-1B models).
SLD150-1 model: When the gearmotor begins to turn, the cam switch on the gearmotor closes, so that the vend switch may be released without interrupting the vending, until the cam has moved
1/4 turn. The cam switch then opens to terminate the vend.
SLD150-1B model: The gearmotor and ice door solenoid will have power and the dispenser will continue to operate as long as the dispense switch is pushed in. This model also has a agitation cycle of 3 seconds every 2 hours. The solenoid does not engage during agitation and no ice is dispensed.
