Ampacity: Minimum ampacity does not indicate typical running current value. Refer to
equipment NAME PLATE data. Use minimum ampacity value for sizi ng branch circuit
conductors up to 25 feet length. For conductor length over 25 feet up to 100 feet,
increase 1 AWG size. Over 100 feet requires 2 or more AWG size increase.
508103901

Branch circuit protection: Proper protection must be provided by either fuse(s) or
HACR type circuit breaker(s). Each ice maker must be provided with a separately
protected circuit with no other load(s). A fused disconnect installed adjacent to each
ice maker is recommended (must be supplied by the installer), and may be required by
local codes. NORMAL protector size is based on rated vol tage and operati on at lower
than extreme temperature li mits. When branch circui t conductors are sized to permit,
increasing the protector size (up to the specified maximum) may avoid nuisance
protector opening under harsh operating conditi ons.
Water supply: Minimum 30 psig supply pressure while the ice maker is filling is
required. Maximum supply pressure is 100 psig. The water fill flow rate is 1 GPM for
each MGB654W machine. Backflow/backsiphonage protection is provided by an
internal air gap (accepted by NSF). If additional protection is requi red by local codes
or authorities, any device(s) and installation of the same, including specification and
cost, are the responsibility of the installation specifier.
Ice maker drain: The size of the gravity drain for the ice maker purge and rinse water
must not be reduced. Individual drains from stacked ice makers may be discharged
into a standpipe or manifold with a minimum 1-1/2 inch air gap at each ice maker
connection.
Liquid condenser cool ant pressure drop: Condenser cool ant pressure drop may reach
20 psig during peak load with 85`F. coolant temperature at recommended refrigerant
high-side pressure. The condenser coolant (water) regulating valve may require
adjustment due to variations in the coolant supply characteristics to provide opti mum
efficiency.
All models are intended FOR INDOOR USE ONLY with PERMANENT CONNECTION
TO THE F IELD ELECTRICAL SUPPLY.
Other operating condition requirements:
Ice maker ambient air temperature: MINIMUM 45°F.; MAXIMUM 90°F.
Potable water and condenser liquid supply:
Temperature: MINIMUM 45°F.; MAXIMUM 90°F.
Pressure: MINIMUM 30 psig; MAXIMUM 100 psig*
*If regulator is used, recommended setti ng is 30 to 50 psig.
KOLD-DRAFT supports all efforts to preserve our environment.

*Approximate cycle time, min. 18
Refrigerant charge (R-404a), oz. 23
Approximate harvest weight, l b . 7.1
* Values are at 90°F. air/70°F. water temperatures with cuber adjusted to produce
fully-formed ice. Greater capacity can be obtained by reducing the water fill level
(lowering the high-level probe) to produce i ce with larger dimples. A slight adjustment
of the probe will result in a noticeable effect on dimple size. The control stream will not
rise over the dam with lower water fill levels than indicated above.
CAUTION: REFRIGERANT CHARGES MUST BE ACCURATELY WEIGHED.
Consult the specification and troubleshooting guide if variations from the following
description of operation are noti ced:
1. Remove the top and front cabinet panels.
2. Be sure that the "ICE-OFF-WASH" switch is in the center (OFF) position.
3. Turn on supply water and power. Be sure that condenser liquid are ready for
use before turning power on. Check for leaks in water/liquid supply
connections.
4. Be sure that pump hoses are connected, then put about one pi nt of clean tap
water into the circulation system to lubricate the pump seal.
5. Move the "ICE-OFF-WASH" switch to the right "WASH" position and observe
the water fill cycle and the pump running. If all water distributor holes do not
produce full streams and the appearance of air i s evident i n the tube, pi nch the
plastic tube connected to the water solenoid valve outlet while water is running
until the streams are full all the way across the distributor tube. Water fill is
complete when the water in the liquid level control tube reaches the high-level
probe. At this time observe that the water shuts off and that there are no water
leaks (dripping i nto the drain pan).
6. Pull the right end of the water plate down, stretching the springs until the pump
stops, and hold until the pump does not re-start when released. The water plate
will open fully to dump the batch of water previously taken in, then close
508103901
-6-
immedi ately. The water pl ate should stop when it is fully closed, and the water
fill cycle will repeat.
7. After the water fill is complete, move the "ICE-OFF-WASH" switch to the left
"ICE" position and observe that the compressor starts, and the water pump
continues to run. T he refrigeration system operation should be checked during
the first few cycles, and any adjustments should be made at this time. Consult
the "adjustments" section in the service manual. Initial i ce making cycles may
exhibit super-cooling of the circulating water so that ice crystals form in the
circulating water ("slush"), possibly stopping the flow momentarily. If water
goes over the control stream dam when circulation resumes after two (2) cycles
AND with all skin panels installed, consult the Factory.
8. Test the bin thermostats by holding some ice against the capillary tubes. If
necessary, adjust the thermostats so that the ice makers shut off within 30
seconds after ice contacts the capillary tubes.
9. Be sure that the drain pans i ce chutes and deflectors are i n place, and that the
electrical control box covers are secured, then replace the cabinet panels
(skins). Start with the SIDE panels, then the FRONT panel, secure the FRONT
panel with (3) screws along the bottom edge, replace the TOP panel and finall y
secure all the panels with (2) screws in the TOP-SIDES of the machine.
10. Discard ice from start-up cycles, then clean and sanitize the bin following the
instructions provided with the bin.
11. Complete and mail the Registrati on Certificate and leave this manual with the
owner/user. Emphasize the "CAUTION: RISK OF PERSONAL INJURY..."
NOTICE ON THE FRONT PAGE, and the importance of the PREVENTATIVE
MAINTENANCE recommendations below.
PREVENTATIVE MAINTENANCE
CLEANING: Usually at 3 to 6 month intervals, depending on water conditions.
INSPECTIONS: During cleaning - at least twice a year.
SERVICE: All such equi pment will require service at some time. Service requirements
will be minimized with faithful preventative maintenance incl uding good housekeeping
at the installation site. A CALL FOR SERVICE AS SOON AS A PO SSIBLE PROBLEM
IS NOTICED MAY AVOID EXTENSIVE REPAIRS.

ICE CUBER CLEANING INST RUCTIONS
CAUTION:
{ RISK OF PERSONAL INJURY OR PROPERTY DAMAGE.
{ Do not use ammonia solutions in cleani ng any part of the ice maker.
{ Do not mix ice machine cl eaner and sanitizer together.
{ Use rubber gloves, eye protection and an apron.
{ Clean up splashes or spillage immediately.
{ Follow these instructions exactly.
1. Mix one bag of KOLD-DRAFT ice machine cleaner (55R-01000-B) in two (2)
quarts of clean, warm water (180°F. MAX.) for each evaporator/water plate
assembly to be cleaned.
2. If the cuber is operating, wait until a harvest cycle occurs then trip the
"ICE-OFF-WASH" switch to "WASH" as soon as the water plate begins to close.
3. Empty all ice from the storage bin and shut off other i ce makers on the same
bin.
4. After the water fill is completed, switch the "ICE-OFF-WASH" to "OFF". While
pinching water level control hose, carefully remove the water level control tube
from the cap. HOLD T HE TUBE HIGH ENOUGH SO THAT THE TUBE DOES
NOT OVERFLOW. Release the hose and pour about hal f of the mixed cleaner
into the tube. Replace the tube on the cap, while pinching water level control
hose, then pour the remaining cleaner into the control stream box.
5. Switch the "ICE-OFF-WASH" to "WASH" and allow the cleaner to circulate for
approximately 15 minutes, then pull the right side of the water plate down until
the pump stops and hold it until the pump will not re-start when released.
6. The water plate will open and dump the cleaner then close immediately, and the
water system will refill. Repeat this dumping and refilling three (3) times to rinse
out all of the cleaning solution.
7. Mix a sanitizing soluti on of two (2) oz. 5-1/4% sodium hypochlorite (household
bleach, or equivalent) and one (1) quart of cl ean water.
8. As in step #4, pour about half of the sanitizing solution into the water level
control tube and the remaining sanitizer into the control stream box.
9. Allow the sanitizing solution to circulate AT LEAST 15 MINUTES, then dump
and rinse two (2) times as described above. If necessary, reset the water level
probes to the proper levels.
10. While the cleaning and sanitizing solutions are circulating, clean, rinse, and
sanitize all accessible parts of the ice-making compartment of the cuber with
clean cloths. Use a cleaning solution of 8 tablespoons (1/2 cup) baking soda
per gallon of warm water, and a sanitizing soluti on of no less than 1 teaspoonful
(5 ml) 5-1/4% sodium hypochl orite per quart of clean water.
11. After cleaning has been completed, trip the "ICE-OFF-WASH" switch to "ICE"
and check to be sure that the cuber is operati ng properly, parti cularly the water
level probes. Then re-assemble and secure all cabinet enclosure panels.
