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.

13. MAKE ELECTRICAL CONNECTIONS

 

Obtain a voltmeter or the special portable line vol­ tage tester recommended in the Carrier Product Information Book. For satisfactory results, the vol­ tage when the unit is running must always remain within 10 percent of the rated nameplate voltage. Check the current supply at the customer's prem­ ises and resolve any wiring problems before pro­ ceeding with the installation. See Table 4 for nec­ essary electrical data.

208V APPLICATION "BUCK AND BOOST"

TRANSFORMER

For application on 208 volt circuits, a transformer is recommended to boost the voltage from 208 volts to 230 volts. The information in Table 5 should be helpful in selecting the transformers. It is selected on the basis of making a 10% voltage boost from 205 volts to 225 volts.

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.

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.

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.

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?

(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.

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?

(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

1.Is the unit level?

2.Have all electrical and piping connections been made?

9. Is the unit quiet?

10.Is the unit clean?

11.Have the installation and warranty cards been filled out?

12.Has the owner been given the Operating Instruc­ tion booklet and has he been instructed on how to operate the machine?

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

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.
