wherever a continuous supply of clear, sanitary ice,
cubed or crushed, is a tangible business asset. The
Carrier Icemaker freezes and delivers up to 200 pounds
of ice per day, at 90° ambient air and 70° entering
water. Quietly, without complicated cutting or chop
ping mechanism, it provides hard, sparkling cubes
or varied grades of crushed ice. The cube, too, is
designed for highest efficiency ... its unique shape
provides more-than-ordinary cooling surface.
COMPACT, ATTRACTIVE CABINET . . . takes up
only 4 square feet of floor area. Smart, modern design,
featuring rounded corners, o bonder!zed, boked-on
sea spray green or white finish, richly trimmed in
stainless steel and chrome . . . complements any
and all furnishings.
ICE CRUSHER. Entirely automatic, electric-motor
driven unit. Delivers crushed ice in three grades —coarse,
medium, or fine. User sets one control knob to "crushed"
and the other to grade as dictated by needs.
REMOVABLE PANELS provide easy access to working
parts. Access for all normal service through removable
front panel.
WELDED-TYPE HERMETIC COMPRESSOR. Quiet,
efficient, permanently oiled and vibrationless. Designed
for long life and trouble-free operation.
EXCLUSIVE DESIGN ICE-MAKING SYSTEM. NO
MOVING PARTS. Freezing coils are soldered to copper
bands and attached, at 8 different points, to each of 13
stainless steel freezing tubes. In operation, ice builds up
on inside wall of tube at these 8 separate points to form
8 cubes in each tube. Freezing completed, automatic
controls reverse cycle, releasing cubes which simply
"gravity drop" into bin or crusher, as “dialed" by user.
COMPLETELY AUTOMATIC. A simple rotary switch
starts the machine, from then on it produces ice auto
matically. When storage bin fills with cubes, or crushed
ice, the machine shuts off automatically, starting again
whenever some ice is used.
STORAGE BIN (bottom section) available in four
sizes — TOO, 160, 240 and 500 pounds capacity. It
has baked-on finish, stainless steel liner and 2 in
ches of insulation on sides. Partition separates
cubes and crushed ice.
SIPHON-INTERCHANGER. Automatically replaces
the water in the Icemaker system at the end of each
freezing cycle. Pure, crystal clear ice is assured, even in
hard water areas, with a minimum of cleaning and maxi
mum productive capacity.

2. SELECT PROPER LOCATION
Select a location for the unit before delivery. The
following should be considered:
1. Convenience - Select a clean dry place as
close as possible to the point of ice consump
tion. Consult the user before deciding.
2. Room Temperatures
Minimum 50 F - Room temperatures below this
may cause erratic control operation.
Maximum 100 F - Room temperatures above
this overload the compressor and reduce unit
capacity.

FIG. 14 - CORRECT WATER LEVEL
Turn on the water and set the float valve to main
tain a water level 3/8 " below the top of the siphon
stcujdpipe for the 26H3 and 1/2" below for the 26H5.
See Fig. 14.
The water level should be set with the pump off,
and checked again with the pump running, after the
water level has settled. To check the Siphon action
let the unit run on "Pump" until the float shuts ofi
the water to the pan. Turn the selector switch to
"Off". The water in the header and the water pipes
will drop down and raise the water pan level until
the Siphon action begins and the water pan is si
phoned out.
If the water pan fails to siphon out, the water level
has been set too low. If the water siphons or over
flows the inner standpipe when the pump is running,
the water level has been set too high.
FLOAT ASSEMBLY
17. REPLACE THE ICE DEFLECTOR
After the float is set, tighten the wing nut on the
float arm and the setscrew to the flat on the float
arm. See Fig. 15.
The bottom of the deflector sets in two clips fas
tened to the inside front wall of the water pan. The
back of the ice deflector rests against the front of
the evaporator shroud. See Fig. 14.

20. CHECK OPERATION
The operation should be as follows:
(a) Freezing for 30 or 40 minutes - compressor
operating, pump operating and hot gas so
lenoid closed. A longer freezing period may
occur where the water supply temperature is
high.
(b) Defrosting for approximately 6 minutes - com
pressor operating, hot gas solenoid open and
water pump off.
(c) Overrun - Time, which is the time between the
falling of the last cube and the start of the
next freezing cycle, should be about 1/2 a
minute to 1-1/2 minutes, to increase overrun
time, raise the setting of the righthand ele
ment (cut in) of the Main Control Thermostat.
(d) The hole in the average ice cube should be
about 3/16" diameter. Run two or three batch
es, since the first harvest will produce-cubes
with larger than overage holes.
21. FINAL CHECK LIST
3. Has the overrun time (par 20C) been set?
4. Have all the controls been checked?
5. Has the voltage been load tested and checked
against nameplate voltage?
6. Have the compressor hold-down bolts been loos
ened so that the compressor rides freely on its
mounting springs?
7. Has the float been set so water will siphon out
at the end of each freezing cycle?
8. Operate the unit for at least two or three cycles.
Is it operating properly?
9. Is the unit quiet?
10. Is the unit clean?
11. Have the installation and warranty cards been
filled out?

1. HOW THE AUTOMATIC ICE MAKER WORKS
The Ice Cube Maker is fully automatic and operates in two alternate cycles - first the freezing cycle, then the
harvesting cycle. The compressor operates continuously during both cycles
SERVICE
26H
FREEZING CYCLE (SEE FIG. 1)
During the freezing cycle water is pumped from the
water pan (13) to a water header (16) at the top of
the unit. From, the water header it flows over individ
ual spreader plates, down the four inside surfaces
of each of the square, stainless steel freezing col
umns (18). Here water is frozen into individual
cubes. This is accomplished by unique evaporator
design. Copper sleeves are bonded to the outside
of each stainless steel column at eight points
spaced along its vertical dimension. Sections of
the evaporator coils are in turn soldered to these
copper bands. Because of the high rate of heat
transfer through the copper and the low conductiv
ity of the stainless steel, individual cubes start
to form inside the columns opposite each copper
band and grow from this point. The hole in the cen
ter is due to continuous water flow - necessary to
form clear cubes.
DEFROST CYCLE (SEE FIG. 2)
When the passage through any one of the columns
becomes restricted because of ice formation, water
backs into the overflow trough, (19), and drops into
the thermostat well,. (21). Here the cold water acti
vates the cut-out side of the Ranco two-bulb con
trol, (35A). This starts the harvest cycle by stop
ping the water pump (14), and opening the hot gas
solenoid valve, (33). The solenoid valve allows hot
gas to pass directly from the condenser, (2), to the
evaporator coil, (6). The cubes are melted loose
and allowed to drop through the ice chute into the
storage compartment, or bin, (37). If the cubes fail
to drop, the water will continue to build up in the
overflow trough and will flow into the safety over
flow well'(23). This actuates a safety switch (24)
and shuts the machine off.
The hot gas passing from the evaporator coil through
the suction line, warms the capillary bulb (35B)
attached to the vertical portion of the suction line
leading from the first accumulator. The warming of
this_ bulb activates the cut-in side of the Ranco
two-bulb control, which starts the machine on the
freezing cycle. As soon as the Ranco control moves
the machine into the freezing cycle, the water pump
is automatically started and the solenoid valve
closes.
