Location:

Ice-O-Matic ice machines are designed to be installed indoors in a controlled environment. Install the ice
machine in a location where it has enough space around it to be accessible for service. A minimum of 6 inches
must be allowed at the back for air circulation on air cooled models. Try to avoid hot, dirty and crowded
locations. Be sure that the location of the machine is within the environmental limitations.

Storage Bin:

Remove the bin packaging. Tip the storage bin on its back, using parts of the packaging to protect the exterior
finish. Remove the skid and install the legs into the threaded holes in the bottom of the bin. Turn the leg
levelers all the way in preparation for leveling later. Return the bin to the upright position.
Note: Do not push the bin into position, but lift it there. Pushing a bin, especially one with ice in it, can cause
damage to the bin legs and mounts.
Install the appropriate bin top according to the instructions provided with the bin top.

Ice machine:

The ice machine is heavy, so the use of a mechanical lift is recommended for lifting the machine high enough
to install on top of the bin. After the unit is placed on the bin, line it up so it is even with the back side. Secure
the ice machine to the bin with the hardware provided with the ice machine. Remove the front panel and
remove any shipping blocks or packaging material.

Proper functioning of the bin door requires the bin door, when it is opened, to be in a stable position. If the ice
machine is too far forward on the bin, the opened door may not be stable, resulting in an unexpected closing of
the bin door.

If the ice machine is to be mounted on a bin or dispenser other than an Ice-O-Matic, refer to the manufacturer’s
instructions for machine mounting. Ice-O-Matic will not be responsible for damage or injury that results from
unexpected closing of the bin door as a result of the ice machine being too far forward on the bin.

Water Limitations:

An ice machine is a food manufacturing plant: it takes a raw material, water and transforms it into a food
product, ice. The purity of the water is very important in obtaining pure ice and maximizing product life. This
section is not intended as a complete resource for water related questions, but it does offer these general
recommendations:

●Check with a water treatment specialist for a water test and recommendations regarding water filters and
treatment.

●In most cases, the water used to make ice should be filtered or treated, depending upon the water.

There is no one type of water filter that is effective in all situations. That is why a water test is important.

RO Water Limitations:

Water conductivity must be no less that 35 microSiemens/cm.

Notice:

Ice-O-Matic ice machines are designed and manufactured with the highest regard for safety and performance
and meet or exceed the standards of UL, NSF and CUL.

Ice-O-Matic assumes no liability or responsibility of any kind for products manufactured by Ice-O-Matic that
have been altered in any way, including the use of any part and/or other components not specifically approved
by Ice-O-Matic.

Ice-O-Matic reserves the right to make design changes and/or improvements at anytime. Specifications and
design are subject to change without notice.

GEM0650/0956/1256 Remote Remote Condenser Location

Use the following for planning the placement of the remote condenser relative to the ice machine.
Location Limits: Remote condenser location must not exceed ANY of the following:

● Maximum rise from the ice machine to the remote condenser is 35 physical feet.

● Maximum drop from the ice machine to the remote condenser is 15 physical feet.

● Physical line set maximum length is 100 feet.

● Calculated

Calculation Formula

● Drop = dd x 6.6 (dd= distance in feet)

● Rise = rd x 1.7 (rd = distance in feet)

● Horizonal Run = hd x 1 (hd = distance in feet)

● Calculation: Drop(s) + Rise(s) + Horizontal Run = dd+rd+hd=Calculated Line Length

Configurations that do NOT meet these requirements must receive written authorization from
Ice-O-Matic. This includes multipass or rack system remote condensers.

Do NOT:

● Route a line set that rises, then falls, then rises.

● Route a line set that falls, then rises, then falls.

Calculation Example 1:

The remote condenser is to be located 5 feet below the ice machine and then 20 feet away horizontally.
(5 feet x 6.6=33 feet) + (20 feet) = 53 feet. This location would be acceptable.

Calculation Example 2:
The remote condenser is to be located 35 feet above the ice machine and then 100 feet away horizontally.
(35 feet x 1.7=59.5 feet) + (100 feet) = 159.5 feet. 159.5 feet is greater than the 150 maximum is NOT
acceptable.

line set length maximum is 150 feet.

Page 7

GEM0650/0956/1256 Remote For the Installer

Remote Condenser Location:

Limited to a 25 foot or a 40 foot length of precharged refrigerant tubing connecting the ice machine to the
remote condenser. The remote condenser must be above or level with the ice machine. Select the best
available location, protecting the remote condenser from extremes of dirt, dust and sun. Meet all applicable
building codes. Usually the services of a licensed electrician are required.

Roof Attachment:

1. Install and attach the remote condenser to the roof of the building, using the methods and practices of

construction that conform to the local building codes, including having a roofing contractor secure the
remote condenser to the roof.

2. Have an electrician connect the remote condenser fan motor wires to the ice machine, using the junction

box at the back of the ice machine.

Precharged Line Set Routing
CAUTION: Do not connect the precharged

tubing until all routing and forming of the
tubing is complete. See the coupling
instructions for connecting information.

1. Each set of precharged tubing refrigerant lines

consists of a 3/8 diameter liquid line and a 1/2
inch diameter discharge line. Both ends of
each line have quick connect couplings, one
end has a Schrader valve connection, that end
goes to the condenser.

Note: The openings in the building ceiling or

wall, listed in the next step, are the minimum
sizes recommended for passing the refrigerant
lines through.

2. Have the roofing contractor cut a minimum

hole for the refrigerant lines of 1.750 inch.
Check local codes, a separate hole may be
required for the electrical power to the
condenser.

CAUTION: DO NOT KINK OR CRIMP

REFRIGERANT TUBING WHEN
INSTALLING IT.

3. Route the refrigerant lines through the roof

opening. Follow straight line routing whenever
possible. Any excess tubing MUST remain
within the building.

4. Spiral the excess length of precharged tubing

inside the building. Use a horizontal spiral
(does not need to be as tight as illustrated) to
avoid any traps in the lines.

5. Have the roofing contractor seal the holes in

the roof per local codes.

CAUTION: The couplings on the sets of

precharged lines are self sealing when
installed properly. Carefully follow the
instructions:
